Traumatic perineal injuries are rare but can result in significant morbidity, particularly when the anal sphincter is injured. The management of such injuries in the pediatric population is rarely noted in the literature. We aimed to describe reconstruction in such patients using lessons learned in reoperative anorectal malformation surgery. This is a single-institution retrospective case series of three pediatric patients who were referred to our institution with pelvic trauma who underwent anal sphincter reconstruction. Three patients aged 5 (female), 12 (male), and 13 (female) years were referred for reconstruction following pelvic trauma involving the anal sphincter, perineal body, and genitourinary system. All three underwent multidisciplinary evaluation with urology and gynecology (for females) and a subsequent repair with anal sphincter reconstruction utilizing a posterior sagittal approach. Two patients had ostomy reversal with appendicostomy for antegrade continence enemas and regained voluntary fecal control. The third patient is awaiting colostomy reversal but has regained volitional urinary control after urethral reconstruction. The experience gained from using the posterior sagittal anorectoplasty approach in reoperations for patients with anorectal malformations can be applied to cases of rectal trauma. Key aspects include mobilizing the rectum, repairing the sphincters, and placing them around the anus, and in females, reconstructing the perineal body. Pediatric pelvic trauma can cause devastating disruptions of physiology and are difficult to treat. Experience from reoperations for anorectal malformations can be applied to these cases, including the use of a multidisciplinary team and posterior sagittal approach.
