title: Anastomotic suture line recurrence of early rectal carcinomas that had been resected by laparoscopic surgery.
abstract: We report herein a case of a 64-year-old woman found to have anastomotic suture line recurrence of an early rectal carcinoma. The patient had undergone laparoscopy-assisted low anterior rectal resection for an early rectal carcinoma 2 years before the anastomotic site recurrence. A follow-up colonoscopy revealed an elevated lesion on the anastomotic suture line. The diagnosis of adenocarcinoma was confirmed by biopsy. The patient underwent a resection of the remnant rectum. Histological examination of the resected specimen showed that the anastomotic site recurrence might have been caused by intraluminal implantation from the primary rectal cancer. We speculate that intraluminal implantation might be caused by insufficient intraoperative rectal irrigation because of limited access often encountered in laparoscopic surgery. We propose that it is necessary to devise a method with which to perform sufficient intraoperative rectal irrigation in laparoscopic surgery for rectal carcinoma.
