Diverticula are small sacs located in which part of the GI tract?

• A. Colon wall
• B. Stomach
• C. Duodenum
• D. Esophagus

Answer: (A)

Diverticula are outpouchings formed when mucosa and submucosa herniate through weak spots in the muscular wall of the colon, most often in the sigmoid colon. This makes the colon wall the correct location. Stomach or duodenum diverticula are uncommon, and esophageal diverticula (like Zenker) are a different entity located higher up in the GI tract. In practice, diverticular disease refers to diverticula in the colon, with possible inflammation called diverticulitis if they become irritated.
