A Case of Primary Cancer of the Small Intestine Treated by Complete Laparoscopic Resection with Intracorporeal Anastomosis

Abstract

A 76-year-old male visited to the clinic because of his black stools and anemia. As the administration of chalybeate was not effective for him, he was referred to our hospital. A double-balloon enteroscopy showed a tumor with ulcer of the ileum, and a biopsy specimen suggested adenocarcinoma. Laparoscopic partial resection of the ileum with intracorporeal anastomosis was performed successfully. The resected specimen revealed a type Ⅱ tumor, measuring 20×22mm. The histopathological examination revealed tubular adenocarcinoma with muscularis propria invasion, but there was no lymphovascular invasion. The incidence of primary small intestinal cancer is relatively rare. This patientʼs postoperative course went well, and there were no complications. The complete laparoscopic resection with intracorporeal anastomosis was a less invasive method and is useful for the small neoplasms of the small intestine.
