Jejunal diverticulosis: complications and management - a case series

Jejunal diverticulosis (JD) is rare (incidence of 0.5%-6%), more common in the elderly, and often asymptomatic. However, complications like diverticulitis, perforation, obstruction and gastrointestinal bleeding pose diagnostic and management challenges. This case series describes five patients with complicated JD. Four had jejunal diverticulitis, two with free perforation requiring emergency surgery, two with chronic inflammation. The fifth patient had severe gastrointestinal bleeding undetected by conventional endoscopy requiring advanced diagnostics. Three patients with diverticulitis underwent successful segmental resection, one was managed conservatively. The patient with gastrointestinal bleeding responded to conservative management without a surgical intervention. JD can cause life threatening complications. Clinicians should suspect it in elderly patients with acute abdominal symptoms or obscure gastrointestinal bleeding. Prompt imaging and individualized management are crucial for optimizing outcomes. This report highlights the need for greater awareness of JD as a differential diagnosis in abdominal pain and gastrointestinal hemorrhage.
