Research highlight: surgical outcomes of gluteal VY plasty after extensive abdominoperineal resection or total pelvic exenteration.

Objective: To describe a suitable alternative technique for reconstruction of the pelvic floor after extensive resection. To review our outcomes of gluteal VY plasty in the reconstruction of the pelvic floor after extensive abdominoperineal resection (conventional or extralevator abdominoperineal resection, total pelvic exenteration, or salvage surgery).

Design: Retrospective cohort study.

Setting: An academic hospital and tertiary referral centre for the treatment of locally advanced or locally recurrent rectal cancer, and salvage surgery in The Netherlands.

Patients: Forty-one consecutive patients who underwent a pelvic floor reconstruction with gluteal VY plasty at Maastricht University Medical Centre between January 2017 and February 2021 were included. The minimum duration of follow-up was 2 years.

Main Outcome Measures: Perineal herniation is the primary outcome measure. Furthermore, the occurrence of minor and major postoperative complications and long-term outcomes were retrospectively assessed.

Results: Thirty-five patients (85.4%) developed one or more complications of whom twenty-one patients experienced minor complications and fourteen patients developed major complications. Fifty-seven percent of complications was not related to the VY reconstruction. Six patients (14.6%) recovered without any postoperative complications during follow-up. Three patients developed a perineal hernia.

Conclusions: A gluteal VY plasty is a suitable technique for reconstruction of the pelvic floor after extensive perineal resections resulting in a low perineal hernia rate, albeit the complication rate remains high in this challenging group of patients.
