Long-term Outcome of Radical Excision Versus Phenolization of the Sinus Tract in Primary Sacrococcygeal Pilonidal Sinus Disease: A Randomized Controlled Trial.

Background: Phenolization of pilonidal sinus disease has been shown to have advantages over radical excision with regard to short-term outcome; however, long-term outcomes are essentially lacking.

Objective: The aim of this randomized controlled trial was to compare the long-term outcome of pit excision and phenolization of the sinus tracts vs radical excision with primary wound closure in pilonidal sinus disease.

Design: Single-center, randomized controlled trial.
