Summary

Background: Extralevator abdominoperineal excision (ELAPE) may cause various surgical complications including disruption of perineal wound, perineal hernia and adhesive small-bowel obstruction. Pelvic peritoneum reconstruction could prevent those complications, but it may not always be achievable, especially in patients with severe pelvic fibrosis after neoadjuvant radiotherapy. Previous study has reported the application of the pelvic peritoneum reconstruction using the bladder peritoneum flap in laparoscopic ELAPE. The aim of the study is to evaluate the short-term clinical, technical and safety outcomes of pelvic peritoneum reconstruction using the bladder peritoneum flap in laparoscopic ELAPE.

Methods/Design: This is a single -center prospective cohort study and fulfill the IDEAL 2A stage principle. Rectal cancer patients after neoadjuvant radiotherapy and about to undergo laparoscopic ELAPE will be included. Main exclusion criteria are being complicated with urgent complications, ASA grade \> 3 and accompanied with mental illness. Patients suffering rigid pelvis or huge perineal peritoneum defect, and having difficulty in primary perineal wound closure will be considered eligible for the baldder peritoneum flap (BPF) group; corresponding rectal cancer patients will be allocated to the control group. After informed consent, 10 patients are planned to be included in the BPF group. Standard laparoscopic ELAPE with pelvic peritoneal floor reconstruction using BPF are to be performed. The surgical safety is to be evaluated after one-year follow-up. Primary endpoints are the occurrence of intraoperative and postoperative complications of pelvic peritoneum reconstruction after ELAPE. Second endpoints are overall complication rate within 30 days after surgery, extent of small intestine falling down to pelvic cavity, and other follow-up consequences within 1 year after surgery.
