Percutaneous cholecystostomy… why, when, what next? A systematic review of past decade.

INTRODUCTION

Percutaneous cholecystostomy tube drainage has played a vital role in management of cholecystitis in patients where surgery is not appropriate. However, management differs from unit to unit and even between different consultants in the same unit. We conducted this systematic review to understand which of these resulted in the best patient outcomes.

METHODS

We conducted a systematic review using the PubMed database for publication between January 2006 to December 2016. Keyword variants of 'cholecystostomy' and 'cholecystitis' were combined to identify potential relevant papers for inclusion.

FINDINGS

We identified 46 studies comprising a total of 312,085 patients from 20 different countries. These papers were reviewed, critically appraised and summarised in table format. Percutaneous cholecystostomy tube drainage is an important treatment modality with an excellent safety profile. It has been used successfully both as a definitive procedure and as a bridge to surgery. There continues to be great variation, however, when it comes to the indications, timing and management of these drains. As far as we are aware, this is the only systematic review to cover the past 10 years. It provides a much-needed update, considering all the technological development and new treatment options in laparoscopic surgery and interventional radiology.
