Laparoscopic Versus Open Restorative Proctocolectomy for Familial Adenomatous Polyposis

Abstract

This study compared outcomes after laparoscopic (LAP) or conventional (open) total proctocolectomy with outcomes after ileal J-pouch anal anastomosis (IPAA) at a single institution. Charts from 133 familial adenomatous polyposis patients (1997-2013) were reviewed. Demographic data (age, sex, color, American Society of Anesthesiologists [ASA] status, previous surgery, and body mass index) and surgical outcomes (length of stay, early and late morbidity, reoperation, and mortality rates) were compared among 63 patients undergoing IPAA. Demographic features were similar among patients (25 open and 38 LAP). Conversely, colorectal cancer at diagnosis prevailed in the open group (60% versus 31.6%; P = .02). Tumor stages (P = .65) and previous surgery index (20% versus 10.5%; P = .46) were similar. Surgical length was longer for LAP (374 versus 281 minutes, P = .003). Short-term complication rates (28% versus 28.9%), hospital stay (10.9 versus 8.9 days), and total long-term reoperations (28% versus 21%) were not statistically different. However, major late morbidity (16% versus 2.6%; P < .001) and late reoperation rates (16% versus 5.2%; P < .05) were greater among open patients. Both groups did not differ regarding pouch failure rates (8% versus 5.2%). There was no operative mortality in the present series. (1) LAP IPAA is a safe procedure associated with a low conversion rate, (2) short-term results showed no clear advantages for both approaches, and (3) a greater risk of major late complications and late reoperations should be expected after open procedures.
