Percutaneous Endoscopic Sigmoid Colostomy

Or commonly known as PEC; This procedure is performed for a number of different indications, with variable research evidence and clinical experience. It is technically similar to percutaneous endoscopic gastrostomy but poses greater risks because large bowel contents are not sterile. However, most patients treated are very frail and the alternative of major surgery carries still higher risks. Evidence on safety and efficacy is sparse, but the procedure has become established practice for carefully selected patients with recurrent sigmoid volvulus and colonic pseudo-obstruction.
