Outcomes of endoscopic pilonidal sinus treatment (EPSiT): a systematic review.

Abstract

Pilonidal sinus 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. More recently minimally invasive approaches have been described. Our aim was to review the current literature on endoscopic pilonidal sinus treatment (EPSiT) and its outcomes. A systematic literature review was conducted and reported in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of EMBASE, MEDLINE and Cochrane Library was conducted in November 2017. Full-text studies on the use of endoscopy for the treatment of pilonidal sinus were included in the review. Initial search results returned 52 articles. Eight studies (eight case series and one randomised control trial) were included in the final qualitative synthesis. These studies demonstrated that EPSiT has good complete healing rates and low recurrence rates. There was also a high level of patient satisfaction and little time taken off work. Two studies reported modifications to the original technique. The main limitation was the lack of comparative studies. Initial studies on EPSiT have shown promising results. However, there is a need for a standardised technique and more comparative studies to validate this novel procedure.
