Prevention of perineal hernia after laparoscopic and robotic abdominoperineal resection: review with illustrative case series of internal hernia through pelvic mesh.

This review is intended to raise awareness of placing a pelvic mesh to prevent perineal hernias in cases of minimally invasive (MIS) abdominoperineal resections (APR) and, in doing so, causing internal hernias through the mesh. In this article, we review the published literature and present an illustrative series of 4 consecutive cases of early internal hernia through a pelvic mesh defect. These meshes were placed to prevent perineal hernias after laparoscopic or robotic APRs.
