Laparoscopic restorative proctectomy - hybrid approach or totally laparoscopic?

Laparoscopic rectal resection is now a technique that is emerging from experience with laparoscopic colonic resection. We review and present our experience with restorative proctectomy for cancer and compare those performed with a hybrid technique with those performed totally laparoscopically.

A total of 177 patients have undergone laparoscopic restorative proctectomy. All of the patients were planned to have the abdominal portion of their surgery performed laparoscopically and to convert to open for the rectal dissection as required. They were then stratified into those that had their surgery performed completely laparoscopically (laparoscopic group - LG), and to those who had their rectal dissection and or transection performed with an open incision (hybrid group - HG).

Short-term outcomes were compared between the LG (n=103) and the HG (n=74). The overall complication rate was higher in the HG (12% versus 35% P<0.001), mainly with a significantly higher pelvic abscess rate and higher rate of post-operative ileus. There were no intraoperative or post-operative deaths. Length of stay was equivalent in both groups (five days). To date, distal recurrence has occurred in 7.7% of the patients, eight in the LG and four in the HG (NS). Two patients, one in each group, have had local recurrence only.

Laparoscopic open or laparoscopic hybrid approaches are techniques that can be used in suitable patients. Both have acceptable morbidity and mortality.
