Bleeding jejunal diverticulum, a challenging case with a review of the literature
Asymptomatic, rare and incidental are the most common words in the literature describing jejunal diverticulosis, yet this disease might be fatal if not anticipated and treated when presenting acutely with massive haemorrhage. Of the pulsion type, and present on the mesenteric side of the small bowel at the entrance site of arteries, jejunal diverticula account for about 80% of small bowel diverticula (another 15% occur on the ileum and the other 5% manifest at both sites). We report a case of symptomatic proximal jejunal diverticulosis in a 66-year-old patient who presented with abdominal pain and melaena. The clinical significance, diagnostic evaluation and treatment of jejunal diverticulosis are reviewed.
