Introduction: Our institution first reported the feasibility and safety of single-incision (SILS) laparoscopic total proctocolectomy and ileal pouch anal anastomosis (TPC/IPAA). In order to improve efficiency while maintaining the cosmetic advantages of SILS even for such technically complex procedures as TPC/IPAA, we have since modified the technique to include the use of a 5mm instrument for retraction placed through the eventual drain site, making this a reduced port technique. The aim of this study was to compare our reduced port laparoscopic (RPL) IPAA with conventional laparoscopic IPAA with respect to short-term outcomes.

Methods: RPL cases were computer-matched to conventional laparocopy 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 with chi-square or Fisher exact tests for categorical and Wilcoxon rank sum test for quantitative data.

Results: 24 RPL patients were case-matched to an equal number of patients who underwent conventional laparoscopic IPAA. The two groups were well-matched for the chosen characteristics (Table 1). Short term outcomes including postoperative complications, length of hospital stay and time to bowel movement were similar between groups. Despite similar diagnosis, previous surgery and comorbidity, operative blood loss (p=0.0001) and operating time (p=0.0215) were significantly lower for the RPL group (Table 1).

Conclusion: RPL IPAA can be performed with comparative short term outcomes as conventional laparoscopy. Further, when performed by surgeons well trained in the laparoscopic technique, RPL IPAA may potentially be associated with intraoperative advantages such as shorter operating time and lower blood loss.
