A Case Report of Laparoscopic Surgery for Metachronous Adenocarcinoma Occurring at the Site of Colostomy after Hartmann's Procedure forRectal Carcinoma

Abstract

The patient was a 77-year-old male with a history of laparoscopic Hartmann's procedure for rectal cancer. Colonoscopy for postoperative follow-up diagnosed a 25mm Borrmann type-2 adenocarcinoma occurring at the site of colostomy. On CT scan, neither direct invasion to the abdominal wall, lymph node metastasis nor distant metastasis was detected. A partial resection of the colon, including the stoma and surrounding skin, was performed laparoscopically. Carcinoma occurring at the site of colostomy is rare, and a case resected by laparoscopic surgery has not been previously reported.
