Preliminary results of Polish national multicenter LILEO study on ileostomy reversal

Introduction: Ileostomy reversal is a common surgical procedure and currently standardized perioperative and surgical protocols are lacking. Aim: LILEO study was designed to perform a multicenter analysis on numerous perioperative parameters and estimation of the incidence of postoperative complications. Materials and methods: The study is an open multicenter prospective cohort study. Preliminary results of the LILEO study after 3 months were available from 18 Polish surgical centers comprising full data of 59 patients who underwent ileostomy reversal. Results: Parameters such as preoperative care, surgical technique, postoperative course and complications were analyzed. Preoperative fasting was used in 49.1% of patients. Fifty nine percent of anastomosis were handsewn and in 72.9% of patients had primary single suture wound closure. Mean length of hospital stay was 7.9 days (min 2 days, max 26 days). Complications occurred overall in 20 patients (33.9%). In 11.9% of patient's complications had grade III A/B in Clavien-Dindo classification. Discussion: The perioperative care in the group of patients undergoing ileostomy reversal still lacks standardized and optimized treatment. Conclusions: Ileostomy removal is a procedure with high risk of postoperative complications. Standardization of perioperative care based on further multicenter national study could result in a decrease of complications rate.
