Abstract
AIM: Avoiding 'mini-laparotomy' to extract a colectomy specimen may decrease wound complications and further improve recovery after laparoscopic surgery. The aim of this study was to develop a new technique for transrectal specimen extraction (TRSE) and to compare it with conventional laparoscopy (CL) for left sided colectomy. METHOD: Eleven patients with benign disease requiring either sigmoid or left colon resection underwent TRSE. The unfired circular stapler was inserted transanally and used as a guide to suture-close the recto-sigmoid junction laparoscopically and as a handle to pull the sutured sigmoid through the opened rectum inside a laparoscopic camera bag. The anvil was inserted into the lumen of the intussuscepted sigmoid and pushed to the level of the anastomosis. The anastomosis was fashioned end-to-end in the first patients and side-to-end in the following patients to improve safety. Intra-operative and postoperative outcomes of patients undergoing TRSE were compared with those of a group of 20 patients undergoing CL, who were matched for type of resection, body mass index and age. RESULTS: The procedure was successful in all but the first patient who was converted to conventional laparoscopic colectomy without any additional morbidity. Two patients in the end-to-end anastomosis group, but none in the side-to-end group, developed peri-anastomotic sepsis. Compared with CL, patients undergoing TRSE did not show any significant differences in operative time, recovery or morbidity. CONCLUSION: Transrectal specimen extraction after left colectomy using the circular stapler technique is feasible. A side-to-end anastomosis appears safer than an end-to-end anastomosis. Further studies are needed to explore the potential advantages of this procedure over CL.
