Quote from "ESPES Manual of Pediatric Minimally Invasive Surgery" by Ciro Esposito, François Becmeur, Henri Steyaert, Philipp Szavay -
"Careful selection of the approach on anorectal malformations reconstruction cannot be stressed enough. A purely posterior sagittal approach only in those patients with high rectum can pose dangerous. First, the dissection travels deep into the pelvis often requiring a coccygectomy in order to reach the peritoneal reflection. Second, if the rectum in high, the bladder can be easily confused with the rectum and leading to misidentification and injury to the urinary tract."
