Percutaneous endoscopic colostomy: a useful technique when surgery is not an option.

Percutaneous endoscopic colostomy (PEC) is a minimally invasive endoscopic procedure that offers an alternative treatment for high-risk patients with sigmoid volvulus or intestinal pseudo-obstruction who have tried conventional treatment options without success or those who are unfit for surgery. The procedure acts as an irrigation or decompressing channel and provides colonic 'fixation' to the anterior abdominal wall. The risk of complications highlights the importance of informed consent for patients and relatives.
