Combined Robotic-Assisted Bio-absorbable Mesh Placement and Gluteal Fasciocutaneous Flap Reconstruction: a Novel Technique for the Repair of a Symptomatic Perineal Hernia Following Extralevator Abdominoperineal Resection for Rectal Cancer

Abstract

Extralevator abdominoperineal resection for rectal cancer has predominated over the common technique during recent years providing better oncologic results. However, extralevator abdominoperineal resection has been associated to a higher incidence of wound complications and perineal hernia. Several risk factors including preoperative pelvic radiotherapy, laparoscopic abdominoperineal resection, women, previous hysterectomy, obesity, coccygectomy, long small bowel mesentery, postoperative wound infection, and open pelvic peritoneum have been correlated to increased perineal hernia rate. Despite the minor clinical manifestation of a perineal hernia, its effect on the quality of life remains remarkable. Therefore, the surgical management of a perineal hernia after abdominoperineal resection is still a challenge for colorectal surgeons. Several techniques have been used including biologic meshes and myocutaneous flaps. Nevertheless, the ideal technique has not yet been proved. During last years, colorectal surgeons have utilized minimally invasive techniques such as robotic repair of perineal hernias. We presented the first case in the literature of a combined approach of robotic-assisted repair using a bio-absorbable mesh and a gluteal fasciocutaneous flap reconstruction.
