PILO - Comparison of the Effectiveness of the Simple Puncture Compared to the Incision of an Abscess on the piLOnidal Sinus
Pilonidal disease is a common disease characterized by the presence of abscess in the intergluteal groove. During periods of abscess, current recommendations are to make a simple incision with daily wicking of the abscess. Direct excision at this time is not recommended because there is a risk of incomplete excision. The principle of directed healing after incision of the abscess results in an average dressing period of 21 days. A definitive resection is recommended after 4 to 6 weeks, when healing has been achieved, in order to limit the risk of infectious recurrence.
An alternative has recently been proposed, consisting of a puncture of the abscess, aimed at emptying it under antibiotic coverage. The major advantage of this treatment is that patients no longer need general anesthesia to flatten the abscess. Although this technique is promising, it is currently not the subject of any published or ongoing randomized controlled study registered on Clinicaltrials.gov.
The research hypothesis is that the two techniques have the same results in terms of recurrence before definitive surgical treatment but that drainage puncture would imply a faster healing time, a lower cost of treatment, a quality of superior support, reduced support time and reduced work stoppage.
This is a single-center, prospective, open-label, randomized study. Patients are screened and included during the emergency room consultation or a scheduled consultation. After verification of the selection criteria and provision of clear, fair and appropriate information, patients are offered to participate in the study. If they accept, consent is signed and randomization is carried out.
The procedure under study is puncture/aspiration. Local anesthesia is previously carried out with 2-5 cc of 1% lidocaine. The puncture is then carried out using a 16 gauge needle. Antibiotic coverage will be offered. A work stoppage is recommended until the day after the puncture/aspiration but the duration is left to the discretion of the surgeon. The patient is systematically reviewed 15 days after the puncture/aspiration with a recommendation for earlier consultation in the event of persistence of redness, discharge, pain or onset of fever. If these symptoms recur or persist, it is recommended to make an incision with packing. In the event of fistulization following the puncture, associated with discharge and skin necrosis, local nursing care is recommended. The definitive resection procedure is then planned 4 to 6 weeks after the puncture/aspiration if the evolution is favorable.
The gold standard procedure is incision of the abscess. This is carried out according to the habits of the department: in the operating room under general or local anesthesia or in consultation (or emergencies) under local anesthesia. The procedure is carried out on an outpatient basis but, if necessary, short-term hospitalization is carried out. Daily wicking is then carried out with nursing care at home until healing. A work stoppage is recommended for a period of approximately 10 days. The patient is systematically reviewed at 15 days with a recommendation for earlier consultation in the event of persistence of redness, discharge, pain or onset of fever. If these symptoms recur or persist, it is recommended to make an incision with packing. The definitive resection procedure is then planned 4 to 6 weeks after the initial operation if the evolution is favorable.
The definitive resection procedure is carried out after the flattening of the abscess has healed. It is recommended to perform resection without closure with nursing-care healing at home with daily packings for 15 days. After the 15-day visit, changing the dressings by wicking is recommended daily until healing.
