Management of sigmoid volvulus using percutaneous endoscopic colostomy.

INTRODUCTION

The aim of this systematic review was to appraise the current literature on the use of percutaneous endoscopic colostomy (PEC) as an alternative to major surgery and endoscopic decompression alone for treating sigmoid volvulus in frail, comorbid patients.

METHODS

A systematic literature search of literature published between April 2000 and January 2017 was carried out using the MEDLINE, Embase™ and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. The search terms were "percutaneous endoscopic colostomy", "PEC", "sigmoidopexy", "sigmoidostomy" and "sigmoid volvulus". The studies identified were screened and those that did not fulfil the inclusion criteria were excluded.

FINDINGS

Seven observational studies and seven case reports (comprising eighty-one patients) were found to match our inclusion criteria. All patients had recurrent sigmoid volvulus and were treated with PEC either with a single PEC tube or with two PEC tubes inserted. Sigmoid volvulus recurred in 10 of the 81 patients; 3 of these individuals developed recurrence with PEC tubes in situ and 7 following tube removal. There were seven deaths after the procedure. The most frequent morbidity associated with PEC tube insertion was site infection (=6).

CONCLUSIONS

Our systematic review highlights the use of PEC as an alternative in managing recurrent sigmoid volvulus in frail, comorbid patients unfit for or refusing surgery, with the best outcomes seen in those patients where two PEC tubes were inserted and remained in situ indefinitely. Further studies are needed to improve the safety and efficacy of the procedure as well as post-procedure care.
