Laparoscopic sigmoid resection for a giant colonic diverticulum - A video vignette.

A Giant Colonic Diverticulum (GCD) is a rare manifestiation of colonic diverticular disease. It is more often located in the sigmoid colon. It is defined by a colonic diverticulum greater than 4cm in diameter (medium size 4-9cm). It is usually located at the anti-mesenteric border of the sigmoid colon. It was first described in 1946, although less than 200 cases are reported in the literature, mostly as case reports. While GCD pathophysiology remains unclear, the "Ball-valve" theory is the most accepted. GCD should be managed with surgical excision. If it presents as acute diverticulitis, it should be treated according to clinical guidelines.
