Endoscopic pilonidal sinus treatment (EPSiT) in recurrent pilonidal disease: a prospective international multicenter study

Background Pilonidal disease (PD) is a common disease of the natal cleft, which can lead to complications including infection and abscess formation. Various operative management options are available, but the ideal technique is still debatable. Recurrent PD after surgical treatment is frequent event for the 25-30% of cases. The present study evaluated endoscopic pilonidal sinus treatment (EPSiT) in recurrent and multi-recurrent PD. Methods Of the consecutive prospective patients with recurrent PD, 122 were enrolled in a prospective international multicenter study conducted at a secondary and tertiary colorectal surgery centers. Primary endpoint was to evaluate short- and long-term outcomes: healing rate/time, morbidity rate, re-recurrence rate, and patient's quality of life (QoL). Results Complete wound healing rate was occurred in 95% of the patient, with a mean complete wound healing time of 29 +/- 12 days. The incomplete healing rate (5%) was significantly related to the number of external openings (p=0.008), and recurrence was reported in six cases (5.1%). Normal daily activity was established on the first postoperative day, and the mean duration before patients returned to work was 3 days. QoL significantly increased between the preoperative stage and 30 days after the EPSiT procedure (45.3 vs. 7.9; p<0.0001). Conclusions The EPSiT procedure seems to be a safe and effective technique in treating even complex recurrent PD. It enables excellent short- and long-term outcomes than various other techniques that are more invasive.
