A Case of Jejunal Duplication in an Adult Undergone Laparoscopic Resection with a Preoperative Diagnosis of Jejunal Diverticula

Abstract

A 67-year-old woman presented with recurrent bouts of abdominal distension and abdominal pain after the meal. An abdominal contrast-enhanced CT scan revealed a localized dilatation at the small intestine in the left upper quadrant of abdomen. Intestinal fluoroscopy demonstrated a cystic dilatation and retention of contrast material in the middle part of the small intestine. Double-balloon enteroscopy revealed dilatation of the lumen at the jejunum, but no obvious point of the obstruction was demonstrated. We performed laparoscopic-assisted partial resection of the small intestine with the preoperative diagnosis of jejunal diverticula. Based on histopathological findings, the lesion was diagnosed as jejunal duplication. Her postoperative course was uneventful and she was discharged from our hospital on the 5^th postoperative day. Abdominal distention and abdominal pain after the meal, of which she had complained before surgery, improved after the operation.

Intestinal duplications are often detected in childhood and the site involved most frequently is the ileocecal region. Jejunal duplication that is diagnosed in adults is rare. We herein report a case which had been undiagnosed with jejunal duplication, until adultfood and was treated by laparoscopic-assisted small bowel resection. Although jejunal duplication is a rare entity, it may have a malignant potential. Laparoscopic resection should be considered if the patient is preoperatively diagnosed. As having jejunal diverticulum.
