Jejuno–ileal diverticulitis: Etiopathogenicity, diagnosis and management

Highlights • Diagnosis is often difficult and delayed because clinical symptoms are not specific.• The etiopathogenesis of jejuno–ileal diverticulosis is unclear.• Flatulent dyspepsia = epigastric pain abdominal discomfort, flatulence one or two hours after meals.• The extraluminal air develops an arrowhead-like shape surrounded by inflammatory tissue when the diverticulum is perforated.• In the presence of complications, surgical resection with reestablishment of the bowel continuity is the preferred treatment option.
