Analysis of clinical and patient-reported outcomes in post-ELAPE perineal reconstruction with IGAP flap – A 5-year review

Abstract

Background: Extralevator abdominoperineal excisions (ELAPE) are now the accepted treatment option for low rectal cancers, which result in large perineal defects necessitating reconstruction. The aim of our study was to assess the clinical outcomes as well as the quality-of-life parameters (QOLP) following these reconstructions. Methods: A series of 27 patients who underwent ELAPE and immediate reconstruction with inferior gluteal artery perforator flaps (IGAP) between December 2013 to December 2018 were retrospectively analysed on patient demographics, disease and treatment, complications, and QOLP. Results: With a mean age of 71.6 years, all patients had low rectal cancers and underwent ELAPE (24 open, 3 lap-assisted) and immediate IGAP flap reconstruction. The follow-up period was 1 year. The overall perineal early minor complication rate was 25.9% and the early major complication rate of 14.8%. QOLP, such as tolerance to sit, perineal pain, perineal aesthetics, showed high patient satisfaction of 77.7%, 40.74%, and 66.6%, respectively at 1 year. The perineal hernia rate was 14.8% with all patients being female (p 0.0407; significant). Conclusion: IGAP flaps are a reliable option for reconstructing post-ELAPE defects with good patient satisfaction and outcomes.
