Percutaneous endoscopic sigmoidopexy using T-fasteners for management of sigmoid volvulus.

Abstract

Sigmoid volvulus (SV) is the third leading cause of large bowel obstruction after colonic neoplasms and diverticular disease. SV has traditionally been managed via endoscopic detorsion and decompression followed by non-emergent surgical resection owing to the high risk of recurrence. Most cases of SV occur in elderly debilitated patients with multiple comorbidities and may not be candidates for surgical resection. Endoscopic sigmoidopexy has been described as an alternative to surgical resection. Here, we describe our experience with endoscopic sigmoidopexy using T-fasteners. Three patients with recurrent SV that were identified as poor surgical candidates by our colorectal surgery team underwent endoscopic sigmoidopexy. The patients received preoperative bowel preparation. A colonoscope was inserted and the site of the volvulus was visualized and assessed for adequate decompression. Subsequently, four points of fixation were identified and T-fasteners were deployed. Two patients underwent successful sigmoidopexy without any complications or recurrence on follow-up. One patient developed post procedure pneumoperitoneum that was successfully treated conservatively; however, he passed away from their underlying comorbidities. Overall, preliminary results for sigmoidopexy using T-fasteners have been promising, offering a potential option to prevent recurrence in high risk patients unsuitable for surgical intervention.
