Abstract

BACKGROUND AND OBJECTIVES: An experimental study was undertaken to evaluate whether a previously described technique for laparoscopic sigmoid resection with intracorporeal resection-anastomosis and specimen removal via a suprapubic incision could be facilitated and applied to the rectum.

METHODS: Ten domestic pigs (median weight 41 kg) underwent low anterior resection of the rectum, which was transected with an articulating endoscopic stapler. Pursestring sutures were fashioned intracorporeally with a laparoscopic pursestring clamp. The anvil of a circular stapler was inserted through a 33 mm port into the colon and pursestring tied intracorporeally. A circular gun with a spike fixed to its shaft was introduced per anum and a double-stapled anastomosis performed.

RESULTS: Complete doughnuts were obtained in all cases and anastomoses were all methylene blue tight. All porcine subjects had an uneventful 5-week postoperative course. The median anastomotic level from the anal verge was 5.2 cm. Histology of colorectal anastomoses revealed healing mucosa.

CONCLUSIONS: The use of articulating endoscopic stapler, laparoscopic pursestring clamp, and circular stapler with a spike fixed to its shaft seems to facilitate a previously described intracorporeal approach to sigmoid resection which was safely applied to the rectum in a porcine model.
