Surgical treatment for cryptoglandular and Crohn's perianal fistulas: Protocol of an umbrella review.

ABSTRACT:

Introduction

A high prevalence of cryptoglandular and Crohn's perianal fistulas has been reported worldwide, and several surgical options are available for the management of anal fistula, with varying clinical efficacy. However, currently, the available evidence for the effectiveness of these surgical approaches are lacking and of concern in terms of the credibility and strength. The purpose of this study is to evaluate the credibility of the published systematic reviews and meta-analyses that assess the efficacy and safety of the surgical options for cryptoglandular and Crohn's perianal fistulas through an umbrella review.
