A Case of Primary Jejunal Cancer Located Near the Treitz Ligament Treated by Laparoscopic-Assisted Partial Small Bowel Resection

Abstract

We report a case of primary jejunal cancer located near the Treitz ligament that was treated by laparoscopic-assisted surgery, along with a review of the pertinent literature. An 80-year old woman visited our hospital with the complaints of melena and anemia. Although we could not detect the cause of the anemia by upper and lower gastrointestinal endoscopy, capsule endoscopy revealed a lesion with slight bleeding in the jejunum. Enteroscopy revealed a tumor measuring about 20 mm in diameter at a site approximately 5 cm anal to the Treitz ligament. Under a preoperative diagnosis of primary jejunal adenocarcinoma, we performed laparoscopic-assisted surgery. After mobilization of the duodenum by a laparoscopic-assisted procedure, tumor resection with lymph node dissection and duodenojejunostomy were performed via a mini-laparotomy. The histopathological diagnosis of the tumor was well-differentiated jejunal adenocarcinoma (StageⅠ). At present, 3 months since the surgery, the patient survives, without any evidence of recurrence.
