Rectopexy for paediatric rectal prolapse: good outcomes but not without postoperative problems.

PURPOSE: Rectopexy is a simple treatment of persisting complete rectal prolapse (RP) or related functional disorders in children. The results of rectopexy have been encouraging with few complications. We describe the postoperative complications and outcome of rectopexy in our institution from 2002 to 2013.
METHODS: Ethical committee accepted the study. Hospital records of 27 successive patients (16 males), median age 7.2 (range 2.8-17) years, who underwent rectopexy (25 laparoscopic, 2 open) were reviewed. Indication for rectopexy included RP (n = 24), solitary rectal ulcer with enterocele (n = 2) and rectocele (n = 1). Nine patients (39 %) were healthy. In the remaining 14 patients, RP was secondary to anorectal malformation (n = 2), bladder exstrophy (n = 1), sacrococcygeal teratoma (n = 1) and myelomeningocele (n = 1) or associated with mental retardation (n = 8) and Asperger's syndrome (n = 1). Five (18 %) patients had constipation. Unexpected postoperative events and complications were rated by Clavien-Dindo classification (Grades I-V).
RESULTS: Seventeen (61 %) patients had postoperative complications (Grade I n = 5, II n = 2 and III n = 7). Readmission was required in 11 (41 %) and reoperation, endoscopy or other surgical procedure in 9 (33 %) patients. Complications included severe faecal obstruction (n = 2), constipation (n = 3), faecal soiling (n = 1) urinary retention (n = 2), enuresis (n = 1), infection (n = 2), residual mucosal prolapse (n = 5), discomfort at defecation (n = 1) and recurrent RP (n = 2). Reoperations included sigmoid resection with re-rectopexy (n = 1), resection of mucosal prolapse (n = 1), suprapubic urinary catheter (n = 2), evacuation of faecal impaction (n = 2), colonoscopy (n = 3), appendicostomy for antegrade continence enema (n = 1). Mental retardation or behavioural disorder increased the risk of postoperative faecal obstruction and constipation RR = 84 (95 % CI 4.3-1600), p = 0.0035. After median follow-up of 4.1 (range 0.6-11) years RP or related condition was cured in 26 patients. Constipation and faecal soiling require management in a total of seven patients.
CONCLUSIONS: Long-term results of rectopexy were good. Postoperative complications from mild to moderate grade were unexpectedly frequent. Preoperative neurobehavioural disorder and constipation increase the risk of postoperative problems and should be mentioned in patient counselling.
