Abstract
BACKGROUND: While diverticular disease is prevalent in the West, the formation of giant colonic diverticula is rare. To date, approximately 200 cases have been reported, with only a handful treated surgically using a minimally invasive approach. Furthermore, the natural history of giant colonic diverticula is not well documented. CASE SUMMARY: This report describes the case of a 66-year-old man who developed a giant colonic diverticulum with primary symptoms including dull and chronic pain in the right lower quadrant at presentation. The patient had undergone several computed tomography scans of the abdomen and pelvis over the previous two years, through which the natural history of this rare entity could be retrospectively observed. The patient was successfully treated with a robot-assisted sigmoid colectomy and had an uneventful recovery with resolution of symptoms during the follow-up. CONCLUSION: This rare case demonstrates the natural history of giant colonic diverticulum formation and supports the feasibility of robot-assisted surgery.
