A <\/span>coccyx fistula<\/b> (medically <\/span>pilonidal sinus<\/span><\/i>(also known colloquially as “coccyx abscess” or “hair fistula”) is a chronic inflammation in the gluteal fold that is usually caused by ingrown hairs. It typically affects young adults (often men) between the ages of 15 and 35. In Germany, around 48 out of every 100,000 people are newly diagnosed with coccyx fistula every year – and the trend is rising. <\/span><\/p>\n

Initially, the disease often goes unnoticed or is underestimated, but if left untreated it can lead to severe pain, recurring abscesses and persistent discharge. Many sufferers ask themselves, <\/span>whether a major operation is really always necessary<\/b> or whether there are also <\/span>gentler, minimally invasive treatment methods<\/b> are available.<\/span><\/p>\n

At the VenaZiel Proctology Center Berlin (DayClinic)<\/b> we specialize in the diagnosis and treatment of coccyx fistula. We offer modern, <\/span>gentle therapy methods<\/b>so that you can recover quickly. <\/span> <\/p>\n

In the following you will learn <\/span>how you can recognize a Pilonidal Sinus<\/b>the causes behind it, <\/span>how the diagnosis is made<\/b>what <\/span>treatment options<\/b> – from conventional to minimally invasive – are available and <\/span>why you are in the best hands with us in Berlin<\/b>.<\/span><\/p>\n

What is a Pilonidal Sinus?<\/strong><\/h2>\n

A coccyx fistula is an inflammation of the subcutaneous fatty tissue in the gluteal fold in which a small cavity forms under the skin. This cavity usually contains <\/span>Hair, dead skin cells and dirt particles<\/b>which the body perceives as foreign bodies. <\/span> <\/p>\n

The name <\/span>Pilonidal sinus<\/span><\/i> means “hair nest cavity” – a reference to the fact that <\/span>ingrown or penetrated hairs<\/b> play a central role in its formation. From this cavity, fine <\/span>Fistulous tracts<\/b> (small tubular connections) that lead to the surface of the skin. <\/span> <\/p>\n

Visible are often <\/span>small punctiform openings<\/b> or pores in the gluteal fold, from which hair or secretions can escape when pressure is applied.<\/span><\/p>\n

Although the term <\/span>coccyx fistula<\/span><\/i> suggests that it is a fistula on the coccyx, in fact only the skin and underlying <\/span>only the skin and underlying tissue are affected<\/b>, not the bone itself. Typically, the sinus occurs above the coccyx in the gluteal cleft. In rare exceptional cases, similar hair nest sinuses have been observed in other parts of the body (e.g., in the navel, groin region, or between the fingers in hairdressers). However, <\/span>Over 90 % of all pilonidal cysts occur in the gluteal fold<\/b>where hair can penetrate the skin particularly easily due to friction and pressure.<\/span><\/p>\n

Causes and risk factors<\/strong><\/h2>\n

The exact cause of coccyx fistula is <\/span>ingrown hair<\/b> or the penetration of hair into the skin of the gluteal fold. The hair bores into the skin through mechanical friction (e.g. when sitting) and triggers a <\/span>Foreign body reaction<\/b> from: The body recognizes the hair as an intruder and reacts with inflammation in order to encapsulate it. <\/span> <\/p>\n

A chronic inflammatory duct (fistula) develops under the skin, which can fill with more hair and sebum. An older theory assumed that this was a congenital malformation, but today the <\/span>Acquired development through hair “nest”<\/b> as the main cause. The following factors favor the development of a coccyx fistula: <\/span><\/p>\n

    \n
  • Heavy body hair:<\/b> Dense, coarse hair growth in the coccygeal region increases the risk of hairs growing into the skin. In fact, most patients have strong hair growth in the gluteal area. (However, people with rather fine body hair can also be affected\u2014the hair factor often plays a role.) <\/span><\/li>\n
  • Young age and male gender:<\/b> Young men between puberty and approximately 35 years of age are most commonly affected. Overall, men are affected approximately 2 to 4 times more frequently than women. Hormonal differences (e.g., testosterone, hair growth distribution) likely contribute to this. However, women can also develop a pilonidal sinus, especially with a corresponding predisposition. <\/span><\/li>\n
  • Prolonged sitting and friction:<\/b> People with predominantly sedentary jobs (office work, frequent drivers such as truck drivers or students) are disproportionately often affected. Sitting for long periods of time <\/span>Pressure and friction<\/b> in the fold of the buttocks, making it easier for hair to be rubbed into the skin. During the Second World War, an unusually large number of American Jeep drivers suffered from pilonidal cysts, which is why the disease is also known colloquially as ” <\/span>Jeep disease<\/b>“Today, however, we know that driving alone is not the cause, but rather the general mechanism of hair and friction.<\/span><\/li>\n
  • Sweating and hygiene:<\/b> Moist, softened skin favors the penetration of hair. Heavy sweating in the crease of the buttocks and insufficient ventilation of the skin (tight clothing) create an environment in which hair and skin flakes stick. <\/span>Poor hygiene<\/b> is controversially discussed as a direct risk factor – scientifically, lack of hygiene is not considered to be the main cause. However, good anal hygiene can help to reduce the risk, while very poor hygiene can promote the development or recurrence of a fistula (empirical value). <\/span><\/li>\n
  • Overweight:<\/b> Many patients with pilonidal sinus are overweight. Higher weight leads to a deeper gluteal cleft and increased sweating, which in turn promotes hair breakage and skin irritation. The skin fold is also subjected to greater pressure when overweight. This increases the risk of sinuses. <\/span><\/li>\n
  • Familial predisposition:<\/b> Occasionally there appears to be a <\/span>genetic component<\/b> There is a family history of pilonidal sinus. It is possible that certain skin or hair conditions are inherited that are more susceptible to ingrown hairs. <\/span><\/li>\n
  • Smoking:<\/b> Although smoking is not a directly proven trigger for coccyx fistulas, nicotine worsens blood circulation and wound healing. <\/span>blood circulation and wound healing<\/b>. Smokers have a higher risk of healing disorders and possibly also recurrences after surgery. It is therefore better to avoid nicotine, especially before and after surgery. <\/span><\/li>\n<\/ul>\n

    The main cause is a combination of hair and mechanical stress. The more risk factors come together (e.g. young, very hairy man with a sedentary job and sweaty skin), the greater the likelihood of developing a Pilonidal Sinus. <\/span><\/p>\n

    Symptoms: How can you recognize a coccyx fistula?<\/strong><\/h2>\n

    The symptoms of a coccyx fistula can vary greatly – from almost unnoticed to highly acute. There are basically three different forms: <\/span><\/p>\n

      \n
    • Asymptomatic fistula:<\/b> In the early stages, the coccyx fistula often causes <\/span>no pain<\/b> and goes unnoticed. Small <\/span>Skin dimples or punctiform openings<\/b> (pits) may be visible in the gluteal cleft, which are noticed incidentally while washing or showering. As long as there is no inflammation, there are no acute symptoms. However, even an asymptomatic sinus can transition to the acute or chronic form at any time. <\/span><\/li>\n
    • Acute pilonidal sinus (abscess):<\/b> This acute form – often referred to colloquially as <\/span>coccyx abscess<\/b> – is characterized by <\/span>sudden severe pain<\/b> noticeable. A <\/span>painful, reddened lump<\/b> above the coccyx, which reacts very sensitively to pressure. Often occurs <\/span>Pus<\/b> from one or more openings, the skin is warm and swollen. The pain intensifies when sitting or sitting down\/standing up. Sometimes it comes to <\/span>Fever and fatigue<\/b>if the inflammation is severe. An acute abscess is a <\/span>urgent situation<\/span><\/i> – medical help is needed quickly to relieve the pus (see treatment).<\/span><\/li>\n
    • Chronic coccyx fistula:<\/b> In many cases, the disease progresses to a chronic stage. Typical symptoms are then <\/span>Persistent or recurring complaints<\/b> over weeks, months or years. Patients report a <\/span>Feeling of pressure or pulling pain<\/b> in the breech area, which occurs particularly when sitting. There is often <\/span>Constant discharge of secretions<\/b>: From small fistula openings a clear yellowish <\/span>clear-yellowish fluid secretion, blood or<\/span><\/i> or <\/span>pus<\/span><\/i> in small amounts, which can lead to soiling of underwear. The skin around the openings is often reddened and itches or burns slightly. Chronic courses occur in episodes\u2014there may be phases with few symptoms in between, but without treatment, the inflammation flares up repeatedly. Unlike an acute abscess, the pain is usually less intense but can impair quality of life over the long term. <\/span><\/li>\n<\/ul>\n

      Note:<\/b> If left untreated, a chronic coccyx fistula can repeatedly become inflamed and encapsulated. Over time <\/span>more and more ducts (fistulas) branch out<\/b>sometimes also laterally outside the gluteal fold. The surrounding skin becomes increasingly scarred. In <\/span>very rare cases<\/b> – In the case of chronically inflamed fistulas that have existed for years, it can even lead to malignant changes in the skin (development of squamous cell carcinoma). A coccyx fistula should therefore be <\/span>never be trivialized<\/span><\/i> or postponed forever, but treated at an early stage.<\/span><\/p>\n

      Diagnosis: How is a Pilonidal Sinus diagnosed?<\/strong><\/h2>\n

      The diagnosis of a coccyx fistula is usually uncomplicated and is made by a specialist (e.g. proctologist or surgeon) based on the typical clinical signs. <\/span>typical clinical signs<\/b>. This is often a <\/span>Visual diagnosis<\/b>The doctor will already recognize the characteristic small fistula openings in the midline, possibly scars from old inflammations, swellings or leaking secretions when examining the gluteal fold. In addition, a thorough <\/span>Medical history<\/b> The patient reports their symptoms (pain, discharge, swelling, fever), the duration of the symptoms and any previous episodes. Questions are also asked about professional activity (prolonged sitting?), hair growth, family history and previous treatments. <\/span><\/p>\n

      During the physical <\/span>examination<\/b> the doctor looks for the following features:<\/span><\/p>\n

        \n
      • Fistula openings (pits):<\/b> Usually, one or more small holes or pores are found precisely in the gluteal cleft on the midline. With gentle pressure, discharge or a tuft of hair can sometimes be expressed. Laterally offset openings also indicate branched fistulas. <\/span><\/li>\n
      • Swelling or hardened lump:<\/b> A bulging, painful swelling can be felt just above the coccyx, especially in the case of an acute abscess. In chronic fistulas, scarred strands can be felt under the skin. <\/span><\/li>\n
      • Pressure pain and redness:<\/b> The area is usually sensitive to pressure. Redness and overheating indicate active inflammation. <\/span><\/li>\n
      • Secretion:<\/b> Purulent, bloody or watery secretion at the openings or in the underwear is a clear sign of an open fistula.<\/span><\/li>\n<\/ul>\n

        Imaging procedures are not always necessary in uncomplicated cases <\/span>not always necessary<\/b>. In <\/span>complex or unclear cases<\/b> however, a <\/span>sonography (ultrasound)<\/b> can be helpful to visualize the extent of fistula tracts and any abscess cavities in the tissue. Particularly before surgical interventions for recurrent fistulas, some centers also use <\/span>MRI<\/b>-examinations in order to obtain a more precise “map” of the fistula tract. Imaging is particularly useful if there is a suspicion of <\/span>Recurrences<\/b> (repeated fistulas after previous operations) or if very extensive courses are suspected. In most cases, however, a clinical examination is sufficient: The coccyx fistula can – for the experienced proctologist – be recognized quite clearly. <\/span><\/p>\n

        Differentiate differential diagnoses<\/strong><\/h3>\n

        It is important to rule out other diseases that can cause similar symptoms in the coccyx region:<\/span><\/p>\n

          \n
        • Anal fistula:<\/b> A fistula originating from the anal canal (e.g. as a result of an anal abscess) can sometimes be confused with a coccyx fistula. However, openings are typical for anal fistulas <\/span>near the anus<\/b> (not on the coccyx) and a connection with rectal complaints. In the case of lateral fistula tracts near the coccyx, the doctor will always check whether an anal fistula is present, as this requires a different treatment. <\/span><\/li>\n
        • Hidradenitis suppurativa (acne inversa):<\/b> This is a chronic skin disease that causes recurring painful lumps and abscesses in body folds (armpit, groin, buttocks). In the chronic stage, fistulas can also develop here. In contrast to coccyx fistula, however, these are usually <\/span>several jobs<\/b> and <\/span>bilateral<\/b> changes are present and it is a systemic skin gland disease.<\/span><\/li>\n
        • Abscesses of other causes:<\/b> An abscess in the gluteal region could theoretically also be caused by a penetrating <\/span>foreign body injury<\/b> or a skin infection. However, the classic coccyx fistula is characterized by the typical pori in the midline mentioned above. <\/span><\/li>\n
        • Cracked skin or fungus:<\/b> Small tears in the skin (rhagades) or psoriasis can cause superficial inflammation and redness in the buttock crease, but without the deep ducts and abscesses of a coccyx fistula. These more harmless findings usually do not require surgical treatment. <\/span><\/li>\n<\/ul>\n

          The specialist will consider all these possibilities. However, in the vast majority of cases <\/span>Medical history and clinical findings<\/b> clearly the diagnosis <\/span>pilonidal sinus<\/span><\/i>. Once the diagnosis has been established, the optimal treatment plan must be determined – the extent of the fistula and the stage (acute vs. chronic) play a decisive role here.<\/span><\/p>\n

          Treatment: What therapies are available?<\/strong><\/h2>\n

          Basically:<\/b> A pronounced coccyx fistula <\/span>does not heal by itself<\/b>. Without adequate treatment, the disease usually progresses – the inflammation remains active and new abscesses can form again and again. <\/span>Conservative measures<\/b> such as ointments, antibiotics or sitz baths can at best provide temporary relief, but do not eliminate the actual cause (the fistula tract). The therapy is therefore <\/span>in most cases involves a surgical procedure<\/span><\/i>. The good news is that today there are various <\/span>Surgical methods<\/b>The treatment options range from classic to minimally invasive and can be selected depending on the findings. Even an acute abscess requires a minor surgical procedure before definitive treatment is carried out. <\/span><\/p>\n

          In the following we present the <\/span>different treatment steps<\/b> and methods – from short-term measures for acute abscesses to the modern minimally invasive techniques that we use in our clinic as a gentle alternative. <\/span>gentle alternative<\/span><\/i> to major operations.<\/span><\/p>\n

          First aid for acute abscess<\/strong><\/h3>\n

          If the coccyx fistula is in an acute <\/span>acute inflammatory episode<\/b> with abscess formation, the first priority is <\/span>rapid relief<\/span><\/i> in the foreground. A bulging pus-filled abscess is treated in a <\/span>minor procedure<\/b> under local anesthesia <\/span>incised<\/b> (cut open) and <\/span>drained<\/b>. The surgeon opens the abscess with an incision (preferably lateral to the midline to promote wound healing) and drains the pus. The severe pressure pain immediately subsides, and the healing process can begin. The resulting cavity is irrigated and possibly provided with a small drain or gauze strip so that it remains open and can continue to heal. This <\/span>Intervention for emergency relief<\/b> is relatively small and can usually be performed on an outpatient basis. However, this <\/span>only the acute danger is averted<\/b>the actual fistula initially remains. Without further treatment, an abscess would soon form again in most cases. For this reason, definitive surgery on the fistula is planned after the abscess has been relieved – as soon as the acute inflammation has subsided and the tissue has calmed down (typically after around 4-6 weeks). <\/span><\/p>\n

          Important: <\/span>Antibiotics<\/b> are usually not a permanent solution for coccyx fistulas <\/span>not a permanent solution<\/span><\/i>. In the case of a large abscess, antibiotics hardly penetrate the area of pus; at most, they can temporarily contain the surrounding infection. Antibiotics are therefore only used <\/span>Short-term bridging<\/b> (e.g. if immediate surgery is not possible). However, complete healing can only be achieved by removing or destroying the fistula tract. <\/span><\/p>\n

          Conservative measures and prevention<\/strong><\/h3>\n

          In early or very mild cases – e.g. if an asymptomatic coccyx fistula is discovered by chance that is not (yet) causing any symptoms – conservative measures can be tried first. These are aimed at <\/span>Minimize risk factors<\/b> and prevent further inflammation:<\/span><\/p>\n

            \n
          • Hair removal:<\/b> To reduce the “regrowth” problem, the hair in the crease of the buttocks can be removed regularly. This is traditionally done by shaving or trimming. However, caution is advised: <\/span>Daily shaving<\/b> can irritate the skin and even promote new hair growths. In fact, constant shaving of the coccyx region is nowadays <\/span>no longer generally recommended<\/span><\/i>as studies have shown no lasting benefit and rather <\/span>increased recurrences<\/span><\/i> have been observed. An alternative is the <\/span>Laser hair removal<\/b> (laser epilation), which has a more permanent effect. However, scientific evidence of improved success is not clear for this either. Some specialists nevertheless rely on laser epilation for recurrent fistulas because it results in less hair regrowth in the long term, but statutory health insurance in Germany usually does not cover the costs. In summary: Careful hair removal <\/span>can<\/span><\/i> be part of prevention (especially in the healing phase after surgery, it is often recommended to keep the wound edge shaved), but should not be exaggerated. <\/span>Important:<\/b> If shaving is carried out, only <\/span>wet and carefully<\/span><\/i> to avoid skin irritation or consider professional hair removal methods.<\/span><\/span> <\/li>\n
          • Hygiene and skin care:<\/b> A <\/span>thorough anal and buttock hygiene<\/b> is the simplest preventive measure. Daily washing of the gluteal cleft with water (and mild, pH-neutral soaps) keeps the pores free of hair and sebum. Afterward, the cleft should be dried well (gentle patting, no rough rubbing). Powder or zinc-containing ointments can help reduce moisture if heavy sweating is a problem. Overall, good hygiene reduces the bacterial load on the skin and could thereby prevent inflammation. While this cannot heal an existing fistula, it helps prevent new abscesses as much as possible. <\/span><\/span> <\/li>\n
          • Weight reduction:<\/b> Overweight patients benefit from <\/span>weight loss<\/b>as this reduces the mechanical stress and moisture in the gluteal fold. A slimmer figure can reduce the recurrence rate and also makes any upcoming operations and wound care easier. <\/span><\/span> <\/li>\n
          • Behavioral changes:<\/b> Prolonged, uninterrupted sitting should be avoided or interrupted more often. If you sit a lot at work, you should take regular breaks to stand up or work standing up in between. Special <\/span>Seat cushion<\/b> (donut cushions with a hole) relieve the coccyx. Very tight-fitting clothing that could chafe should also be avoided. While these measures are not a guarantee, they reduce mechanical irritation. <\/span><\/span> <\/li>\n
          • Stop smoking:<\/b> As mentioned, smoking worsens wound healing. A <\/span>Abstaining from nicotine<\/b> is particularly advisable before and after surgical treatment to ensure optimal healing.<\/span><\/li>\n<\/ul>\n

            Important:<\/b> Conservative measures can possibly slow down the progression or keep smaller, not yet inflamed fistulas stable. <\/span>Healing<\/b> However, they cannot correct an established coccyx fistula, as the duct remains deep. Sooner or later, surgery is therefore usually necessary, especially if symptoms occur. Nevertheless, hygiene, hair removal and co. <\/span>Accompanying measures<\/span><\/i> – both to prevent recurrence after surgery and to generally reduce the risk of inflammation.<\/span><\/p>\n

            Minimally invasive procedures<\/b>: Modern procedures such as pit-picking surgery or endoscopic fistula therapy make it possible to remove a pilonidal sinus through tiny incisions or using camera technology. The patient can often be treated on an outpatient basis in a comfortable supine position. The procedures cause <\/span>Less wound pain<\/b> and heal faster, allowing patients to return to their everyday lives more quickly. The picture demonstrates how a gentle proctological procedure is prepared in our clinic – the focus is on putting as little strain as possible on the tissue. <\/span><\/p>\n

            Surgical treatment methods: classic vs. minimally invasive<\/strong><\/h3>\n

            Coccyx fistulas have been treated surgically since time immemorial, but the <\/span>surgical procedures<\/b> have developed significantly in recent years. There are <\/span>conventional operations<\/b>in which the diseased tissue is generously excised, and <\/span>modern minimally invasive techniques<\/b>that require minimal incisions. Which method is used depends on the extent of the fistula, the stage, and also the surgeon’s experience. Often the rule is: <\/span>As radical as necessary, as gentle as possible.<\/span><\/i> Below we compare the most important procedures:<\/span><\/p>\n

            Conventional surgical procedures (excision)<\/strong><\/h3>\n

            For a long time, the classic standard treatment for coccyx fistula was <\/span>excision<\/b>This is the complete surgical excision of the fistula system including all inflammatory tissue. In the process – usually under general anesthesia – a <\/span>oval area<\/b> around the fistula. There are two basic procedures after excision: <\/span><\/p>\n

              \n
            • Open wound healing (secondary healing):<\/b> Here the wound is left <\/span>open<\/span><\/i>without suturing it. The wound cavity heals from bottom to top as new tissue grows in. The advantage of this method: The recurrence risk is relatively low, as all fistula tracts have truly been removed and there is no tension on a fresh suture. Studies show that with open wound healing the <\/span>recurrence rate can be less than 10 %.<\/b> can be less than 10%.
              \nThe disadvantage is the <\/span>long healing time<\/b>Depending on the size of the wound, it can take 4-8 weeks (sometimes longer) for the wound to completely heal. During this time, daily wound care is necessary (irrigation, dressing changes) and the patient must take it easy. Many people find the open wound psychologically stressful. Nevertheless, this procedure is recommended above all for complex, extensive fistulas because it heals most reliably. <\/span><\/span> <\/li>\n
            • Primary wound closure (direct suturing):<\/b> Here, after excising the fistula, the wound is immediately sutured closed. This closes the wound cavity and healing occurs faster (often in 2\u20133 weeks). Patients are able to work again more quickly and care is easier, as there is no deep open wound to manage. However, with this approach the <\/span>Higher risk of relapse<\/b> – Depending on the study, fistulas recur in up to 15-20% of cases. In particular, an occlusion <\/span>exactly in the gluteal fold (in the middle)<\/span><\/i> is considered unfavorable, as high tension and moisture prevail there, which favors healing disorders. <\/span>Important:<\/b> Modern guidelines advise against treating a coccyx fistula with a <\/span>central suture<\/span><\/i> to close. Instead, techniques have been developed in which the closure <\/span>laterally offset<\/b> to relieve the load on the loaded pore tip.<\/span><\/span> <\/li>\n
            • Plastic flap procedure (off-midline closure):<\/b> In order to combine the advantages of rapid healing and a low recurrence rate, many surgeons now use plastic surgery methods. After the excision, a <\/span>Tissue flap<\/b> to close the wound, leaving the new scar outside the gluteal fold. <\/span>outside the gluteal fold<\/b> comes to rest. Examples are the <\/span>Karydakis operation<\/b> or the <\/span>Limberg flap surgery<\/b>. Here, the wound is closed obliquely or asymmetrically, sometimes with removal of a small skin spindle, so that the former gluteal furrow is flattened. Result: better ventilation, less hair accumulation, and less tension on the scar. Off-midline procedures show in studies <\/span>excellent healing rates<\/b> and significantly <\/span>shorter wound healing times<\/b> compared to open healing.
              \nIn a meta-analysis, the healing time according to Karydakis\/Limberg was significantly shorter, and these techniques are used especially for larger findings or after recurrences. <\/span>larger findings or after recurrences<\/b> recommended. Recurrence rates are usually below 5\u201310% depending on the technique. The disadvantage is, of course, a somewhat larger procedure with general anesthesia and the need for some bed rest until the flap sutures have held securely. Overall, however, plastic coverage is considered <\/span>State-of-the-art<\/b> for recurring or severe cases to achieve a permanent solution.<\/span><\/li>\n<\/ul>\n

              In summary, conventional operations are sometimes unavoidable – especially if the fistula is very extensive or has already occurred several times (recurrence) and is scarred. They offer the <\/span>Highest probability of success<\/b>but are sometimes accompanied by prolonged healing and scarring. Fortunately, there are now <\/span>suitable cases<\/b> less invasive alternatives.<\/span><\/p>\n

              Minimally invasive techniques<\/b><\/p>\n

              In recent years, several minimally <\/span>minimally invasive procedures<\/b> have been developed with the aim of treating the coccyx fistula <\/span>with as little trauma as possible<\/span><\/i> to treat. These methods are particularly suitable for <\/span>Smaller fistulas that have not yet been operated on<\/b> often very successful. The advantages are obvious: <\/span>Minor wounds<\/b>less pain, shorter downtimes – many patients can be treated with virtually no interruption to work. However, studies show that minimally invasive procedures tend to have a <\/span>Slightly higher relapse rate<\/b> than radical excision. Nevertheless, they are an attractive option due to their gentleness and repeatability. The most important techniques include: <\/span><\/p>\n

                \n
              • Pit-picking (also known as “sensory clearing”):<\/b> This method goes back to the surgeon John Bascom. It involves <\/span>local anesthesia<\/b> only the small visible fistula openings (<\/span>pits<\/span><\/i>) together with the fistula tract behind them <\/span>punched out<\/b> or scraped out. Only a few <\/span>Tiny incisions (approx. 5 mm)<\/b>through which the surgeon removes the tufts of hair and inflammatory tissue. The resulting mini-holes are left open to heal or sutured with 1-2 stitches. Pit picking can usually be performed on an outpatient basis.
                \nThe wounds heal in 1-2 weeks and the patient has hardly any pain or restrictions – they can often walk, sit and work normally again the very next day.
                \n<\/span>Disadvantage:<\/b> Pit picking is only suitable if the fistula tracts are <\/span>superficial and not very branched<\/span><\/i> are (ideally only a few pits present). In very extensive or chronic findings, it is often not sufficient. Additionally, it should be noted that the recurrence rate with pit-picking is higher; studies indicate recurrence rates around 20\u201330%. However, pit-picking can be relatively easily <\/span>Perform again<\/span><\/i>as there is hardly any scarring. It is therefore a gentle first attempt for early cases. <\/span><\/span> <\/li>\n
              • Endoscopic fistula therapy (EPSiT – Endoscopic Pilonidal Sinus Treatment):<\/b> This is an innovative procedure that uses a fine endoscope to <\/span>fine endoscope<\/b> is performed. Under spinal or short general anaesthesia, the surgeon inserts a miniaturized camera system directly into the fistula tract. Under visualization, the <\/span>Hair, pus and deposits<\/b> in the duct <\/span>cleared out<\/b> and the fistula tracts are burned out from the inside or cut out with mini probe scissors. So you work <\/span>from the inside out<\/span><\/i>without a large skin incision. At the end, the inner fistula wall is cauterized, e.g., with a coagulation probe. The external skin openings remain very small. Advantage: The physician can <\/span>Targeted all ramifications<\/b> under camera vision and treat them; healthy tissue is hardly injured.
                \nHealing proceeds with minimal pain. After a few days, the patient can often sit again almost without discomfort. Initial studies on EPSiT also show recurrence rates in the range of 15\u201320%, sometimes even lower when the technique is correctly applied. However, EPSiT is somewhat more complex (requires special equipment and experience) and is not available in all clinics. At our VenaZiel DayKlinik, we rely on such modern technologies to offer our patients the <\/span>most gentle treatment<\/span><\/i> possible.<\/span><\/span> <\/li>\n
              • Laser therapy (FiLaC\u00ae\/SiLaC):<\/b> Similar to the endoscopic method, the fistula tract is treated from the inside – but using <\/span>laser fibers<\/b>. With the FiLaC method (<\/span>Fistula Tract Laser Closure<\/span><\/i>), a flexible laser fiber is inserted into the duct. By slowly retracting the fiber, the inner wall of the fistula is <\/span>Scabbed and sealed using laser energy<\/b>. The surrounding tissue contracts and the canal should heal. This procedure is performed under local anesthesia or brief anesthesia. The outer openings are often scraped out beforehand (similar to pit-picking) and then also closed with a laser if necessary.
                \nAdvantages:<\/strong> again minimal tissue damage and relatively rapid recovery. Initial experience shows success rates comparable to other minimally invasive methods. Official long-term data are still pending, so laser is currently considered <\/span>Supplementary option<\/span><\/i>. However, it may be worth a try for patients who do not want major surgery, as the stress involved is low. If a laser attempt is unsuccessful, surgery can still be performed. <\/span><\/span> <\/li>\n
              • Other procedures:<\/b> In some cases <\/span>Chemicals (phenol)<\/b> for obliteration of the fistula tract. Crystalline phenol is introduced into the cleaned fistula, which is intended to cause hardening and scarring. However, this method is hardly used today, as it is unreliable and phenol can also have side effects on the open wound. Also experimental are <\/span>Bonding techniques<\/b> (e.g. fibrin glue) to close the duct – their success is limited. Overall, pit-picking, endoscopic and laser methods have emerged as the most common minimally invasive options. <\/span><\/li>\n<\/ul>\n

                Success rate and selection:<\/b> In general, classic procedures (complete excision with open or flap closure) have the lowest recurrence rates, while minimally invasive procedures have the higher <\/span>Patient protection<\/span><\/i> but need to be repeated somewhat more often. The choice of method should be made on an individual basis. <\/span>Small, first-time fistulas<\/b> – especially in patients who are reluctant to have a long downtime – can initially be treated using a minimally invasive approach. <\/span>Larger or complex fistulas<\/b> and those that are already one or more recurrences are often better treated with a more extensive operation (possibly with flap plasty) to achieve definitive resolution. The experience of the treating surgeon with the respective techniques is also important. In specialized centers (such as our proctological DayKlinik), minimally invasive methods are routinely offered and mastered\u2014while in less specialized facilities, radical excision is sometimes performed immediately. <\/span><\/p>\n

                Aftercare, healing and prognosis<\/strong><\/h3>\n

                Regardless of the procedure chosen, the <\/span>aftercare<\/b> of a coccyx fistula is crucial for successful healing. After an operation – whether large or small – patients receive precise instructions: <\/span><\/p>\n

                  \n
                • The wound (or wounds in the case of multiple cuts) must be <\/span>kept clean<\/b> become. Daily careful <\/span>Showers<\/b> rinsing the wound area with clear water is usually recommended to rinse off secretions. Sitz baths with disinfectant additives can provide relief for open wounds (seek medical advice). <\/span><\/li>\n
                • Wound checks<\/b> with the physician at regular intervals are important. For open wounds, dressing changes are initially performed frequently by medical personnel to monitor healing. For sutured wounds, stitches are removed after approximately 10\u201314 days (if not absorbable). <\/span><\/li>\n
                • Pressure relief:<\/b> Especially with fresh sutures, pressure on the coccygeal region should be avoided. Patients are advised to sit laterally as much as possible or use a soft cushion. Strong straining (during bowel movements) and heavy physical work should be avoided in the first two weeks to prevent wound dehiscence. <\/span><\/li>\n
                • Hygiene & hair removal:<\/b> Once the wound has healed, it is advisable to keep the area <\/span>keep the area free of hair<\/b> (as discussed above, preferably using moderate methods). Care should also be taken to ensure meticulous cleanliness – a daily shower is essential to prevent hair and dirt nests from forming in the first place. <\/span><\/li>\n
                • Check-ups:<\/b> Many surgeons ask for a follow-up visit after a few months, as recurrences often appear within the first year. An inspection of the coccyx region some time after healing can detect any neoplasms at an early stage so that countermeasures can be taken in good time. <\/span><\/li>\n<\/ul>\n

                  The <\/span>healing time<\/b> varies greatly depending on the procedure:<\/span><\/p>\n

                    \n
                  • After <\/span>pit-picking<\/b> or minor operations, patients are often fit again after just a few days. The wounds close within 1-3 weeks. <\/span><\/li>\n
                  • After <\/span>major excision with suture<\/b> After an operation, a recovery period of around 2-4 weeks is expected (until stitches are removed and the wound is stable). Office activities are often possible again earlier, physically strenuous activities a little later. <\/span><\/li>\n
                  • For <\/span>open wound healing<\/b> complete epithelialization can take 6\u20138 weeks or more, as mentioned. Here, one must be more patient and consistently perform wound care. However, absences of several months are rather rare\u2014often, at least limited activity is possible again after a few weeks, as long as the wound is cared for. <\/span><\/li>\n<\/ul>\n

                    The <\/span>forecast<\/b> is overall <\/span>good<\/span><\/i>provided the fistula has been treated correctly. A coccyx fistula is annoying and can flare up again and again, but it is <\/span>benign<\/span><\/i> and – properly addressed – also <\/span>curable<\/span><\/i>. As discussed, the recurrence rates depend heavily on the method. Open procedures sometimes offer recurrence rates of less than 10 %, while primary central occlusions have higher rates of around 15-20 %. Minimally invasive methods are roughly in between or sometimes higher (e.g. ~20-30 % with a pure pit-picking strategy). <\/span><\/p>\n

                    Important to know: <\/span>A relapse (recurrence)<\/b> does not necessarily mean failure\u2014sometimes one simply needs to “step it up” and apply the next therapy level. Thus, after an unsuccessful pit-picking, a classic operation can still be performed, or the minimally invasive procedure can be repeated. Experience shows that with increasing consistency, definitive healing is usually achieved at some point. <\/span><\/p>\n

                    Conclusion: Modern treatment of coccyx fistula in Berlin<\/strong><\/h2>\n

                    The Pilonidal Sinus (<\/span>pilonidal sinus<\/span><\/i>) is a common but easily treatable disease in the field of proctology. The decisive factor is, <\/span>See a specialist in good time<\/b> instead of waiting a long time – because early interventions can often be smaller than late operations. Thanks to modern techniques, it is now possible to treat many coccyx fistulas <\/span>Minimally invasive and outpatient<\/b> which enables patients to recover quickly. Conservative measures such as hygiene and hair removal can help, but are no substitute for surgery once a fistula has developed. <\/span><\/p>\n
