Sacroperineal Reconstruction With Inferior Gluteal Artery Perforator Flaps After Resection of Locally Advanced...

Modern interdisciplinary concepts with involvement of various surgical specialties can considerably reduce perioperative morbidity after sacroperineal resection of locally advanced primary or recurrent anorectal malignancies. Resultant defects can represent a major challenge for reconstruction particularly with chemoradiotherapy. The aim is to assess the long-term outcomes of sacroperineal reconstruction using inferior gluteal artery perforator flaps.We performed a retrospective data analysis on 31 patients who were treated with inferior gluteal artery perforator flaps (n = 61) over the period 2009-2021. The demographic data, comorbidities, operative details, and outcomes with special focus on wound infection and dehiscence were recorded.The median age was 42 year (range, 25-82 years) with preponderance of males (n = 21). The follow-up period ranged from 6 to 80 months. Early minor complications included superficial wound dehiscence (3), which was managed conservatively, whereas the major (2) included deep wound collection and infection (1), which required surgical drainage, and perineal hernia, which required repair. All flaps survived completely.Inferior gluteal artery perforator flaps are safe, robust, and reliable with less donor side morbidity and positive impact on quality of life. It should be considered as a valuable tool in the reconstructive armamentarium of sacroperineal defects within a multidisciplinary setting.
