Case-Matched Comparison of Long-Term Functional and Quality of Life Outcomes Following Laparoscopic Versus Open Ileal Pouch-Anal Anastomosis.

Abstract

Laparoscopic ileal pouch-anal anastomosis (IPAA) is associated with recovery benefits when compared with open IPAA. There is limited data on long-term quality of life and functional outcomes, which this study aimed to assess. An IRB-approved, prospectively maintained database was queried to identify patients undergoing laparoscopic IPAA (L), case-matched with open IPAA (O) based on age ± 5years, gender, body mass index (BMI) ± 5kg/m2, diagnosis, date of surgery ± 3years, stapled/handsewn anastomosis, omission of diverting loop ileostomy and length of follow-up ± 3years. We assessed functional results, dietary, social, work, sexual restrictions and the Cleveland Clinic global quality of life score (CGQoL) at 1, 2, 3, 4, 5 and 10years postoperatively. Functional outcomes were assessed based on number of stools (day/night) and seepage protection use (day/night). Variables were evaluated with Kaplan-Meier survival curves, uni- and multivariable analyses. Out of 4595 IPAAs, 529 patients underwent L, of whom 404 patients were well matched 1:1 to an equivalent number of O based on all criteria. Median follow-ups were 2 (0.5-17.8) versus 2.4 (0.5-22.2) years in L versus O, respectively (p = 0.18). L was associated with significantly decreased number of stools at night and less frequent pad usage at 1year, both during the day and at night. Functional outcomes became similar during further follow-up. L was also associated with improved overall CGQoL, and energy scores at 1year postoperatively, and decreased social restrictions for 1-2years. There were no significant differences in quality of health, dietary, work or sexual restrictions. Laparoscopy was not associated with increased risk of pouch failure (p = 0.07) or significantly different causes of pouch failure when compared to O. Laparoscopic and open IPAA are associated with equivalent long-term functional outcomes, quality of life and pouch survival rates. Laparoscopic technique is associated with temporary benefits lasting 1 or 2years.
