Reduced port versus conventional laparoscopic total proctocolectomy and ileal J pouch-anal anastomosis

摘要

Background: The feasibility and safety of single-incision laparoscopic total proctocolectomy (TPC) and ileal pouch anal anastomosis (IPAA) were first reported in 2010. To improve accuracy and efficiency while maintaining the cosmetic advantages of single-incision laparoscopic surgery, we have since modified the technique to include the use of a 5-mm instrument placed through the eventual drain site. The aim of this study is to compare reduced port laparoscopic (RPL) IPAA with conventional laparoscopic IPAA with respect to short-term outcomes to assess safety. Methods: RPL cases were matched to conventional laparoscopy cases for patient age (±5 years), body mass index, gender, diagnosis, type and number of stages of surgical procedure, American Society of Anesthesiologists (ASA) classification, and year of surgery (±3 years). Groups were compared using χ2 or Fisher exact tests for categorical and Wilcoxon rank-sum test for quantitative data. Results: Twenty-four RPL patients were case-matched to an equal number of patients who underwent conventional laparoscopic IPAA. Short-term outcomes including postoperative complications, length of hospital stay, and time to first bowel movement were similar between groups. Despite similar diagnosis, previous surgery, and comorbidity, operative blood loss (p 0.001) and operating time (p = 0.02) were lower for the RPL group. Conclusion RPL IPAA can be safely performed with shortterm outcomes comparable to conventional laparoscopy.
