Complicated duodenal-jejunal diverticulosis: case report.

Background: Bleedings such as melaena are related to diseases in the upper gastrointestinal tract. In 0.06% - 5% of cases these incidents are due to the presence of diverticula of the small intestine, which are asymptomatic and unrecognized in most patients and are only fully diagnosed in cases when complications occur.

Case Report: An 88-year old male patient presented with severe anaemia, asthenia and melaena in the previous days. An esophagogastroduodenoscopy (EGDS) was performed with evidence of stenosis in the second part of the duodenum and a blood clot in the posterior wall without signs of active bleeding. A complete CT scan was carried out of the thorax, abdomen and pelvis using a contrast medium, which revealed a dilation of the stomach and of the first part of the duodenum with a diverticulum of the second. On the fourth day following admission the patient suffered a haemorrhagic shock and underwent an emergency surgical procedure with a bleeding diverticulum on the posterior wall of the duodenum tightly adhering to the pancreas being found. Therefore an atypical duodenal-jejunal resection was performed using a gastrojejunal Roux-en-Y bypass and the closure of the duodenal stump.

Conclusion: Diverticulosis of the duodenum and small intestine is considered a rare disease. According to the literature, treatment should be conservative, and surgical options considered only in those very rare cases of complicated and life-threatening diverticulosis.
