Abstract

Purpose of Review

Small bowel diverticulosis is a well-known clinical entity whose diagnosis and management has evolved in recent years. This review covers pathophysiology, incidence, and prevalence, and it also provides an update on modern diagnosis and management. Meckel’s diverticula are covered elsewhere in this volume.

Recent Findings

CT scan and MRI have largely supplanted barium follow-through for diagnosis. No intervention is needed in asymptomatic individuals. Endoscopic management is playing an increasing role for both bleeding and resection of intraduodenal diverticula, but surgical intervention remains the only definitive intervention for other complications like diverticulitis and small bowel obstruction.

Summary

Small bowel diverticulosis is an uncommon condition which is associated with numerous possible complications. While endoscopy is playing an increasingly large role in management, surgical resection remains the treatment of choice for most complications. A high index of suspicion is needed in order to diagnose this entity.
