Primary analysis of pedicle rectus abdominis muscular flap for pelvic floor reconstruction afterpelvic exenteration

Objective?To explore the feasibility and short-term effectiveness of pelvic floor reconstruction by pedicle rectus abdominis muscular flap after pelvic exenteration. Methods?Eight patients with pelvic floor reconstruction by pedicle rectus abdominis muscular flap after pelvic exenteration between October 2019 and June 2021 were reviewed and analysed retrospectively. Results?The patients were from 39 to 68 years old(median age 57.5), 2 pelvic floor reconstructions with partial pedicle rectus abdominis muscular flap, 6 pelvic floor reconstructions with whole pedicle rectus abdominis muscular flap, the reconstruction time were 60 to 90 minutes. 1 case had ureteral fistula and underwent further surgical repair. 2 cases complained of increased vaginal discharge, they were all improved with anti infection therapy after 1 month and without any further surgical intervention. Abdominal incision infection occurred in 2 cases, and the wound healed after debridement. The patients were followed up 2 to 13 months (median 6.5 months), 1 case died of tumor recurrece 4 months after surgery, and 7 patients survived. There was no late complication, such as bowel obstruction, bowel perforation and fistulas. There was no early and late muscular flap related complications. Conclusion?The pedicled rectus abdominis muscular flap is a safe, effective, simple and rapid method for pelvic floor reconstruction after pelvic exenteration.
