Lessons learned from stomal complications in children with cutaneous catheterizable continent stomas

OBJECTIVE To evaluate the impact of various factors that might ultimately influence the stoma complication rate associated with the construction of a continent catheterizable urinary (CCU) and Malone antegrade colonic enema (MACE) stoma in children. PATIENTS AND METHODS Retrospectively, we reviewed our experience in patients who had a CCU and/or MACE stoma reconstructed at our institution from 1992 to 2003. Diagnosis, type of stoma constructed (CCU vs MACE), single vs dual stomas, stomal site, conduit material (appendix, split appendix, Monti‐Yang or ureter), sex, age, patient mobility and body mass index, race and concomitant surgery (e.g. bladder augmentation with or without bladder neck reconstruction) were evaluated for stoma‐related complications. In all, 109 patients (64 males and 45 female), with a mean (sd, range) age of 8.6 (5.7, 2–37) years, had 151 stomas constructed during the period of analysis, comprising 56 CCU only, 11 MACE only and 42 (84 stomas) both simultaneously. RESULTS The mean (range) follow‐up was 48 (6–144) months. The primary diagnoses were neurogenic bladder in 60 (55%), bladder exstrophy/epispadias in 17 (16%) and posterior urethral valves in 11 (9%) patients. The umbilicus was the primary site for the CCU stoma in 88 of 98 (90%) cases, while the right lower quadrant was the primary site for MACE in 46 of 53 (87%). After surgery complete stomal continence was provided in 95 of 98 (97%) CCU stoma, whereas the MACE was successful in 52 of 53 (99%). The stoma‐related complications included stenosis in 27, leakage in eight, false passage in four, atrophy in two, keloid in one, and breakdown of the stoma in two. Individually, only greater age and a primary diagnosis of neurogenic bladder were independent risk factors associated with an increased rate of stomal complications and higher incidence of revision (P
