Summary

Diverticular disease affecting the small bowel, specifically the jejunum, is rare with an incidence of 1–2% in the general population. We report a case of a 67-year-old man who presented with clinical signs and symptoms suggesting peptic ulcer disease, but complications resulting from small bowel diverticular disease should be borne in mind as they may mimic the above pathology. The diagnosis of small bowel diverticulosis can often be challenging in someone who presents or develops massive gastrointestinal bleed, and in these cases a prompt diagnosis is of the utmost importance. The best line of treatment in these cases would be a laparascopic assisted exploration or an exploratory laparotomy with resection of the lesion and primary anastomosis.
