| Popis: | Objective To evaluate human acellular dermis (HAD) as an adjunct during bladder neck transection (BNT) by comparing surgical outcomes with other types of tissue interposition. Methods A prospectively maintained institutional database of exstrophy-epispadias complex (EEC) patients was reviewed for those who underwent a BNT with at least 6 months follow-up. The primary outcome was the occurrence of BNT-related fistulas. Results In total, 147 EEC patients underwent a BNT with a mean follow-up time of 6.9 years (range 0.52-23.35 years). There were 124 (84.4%) classic exstrophy patients, 22 (15.0%) cloacal exstrophy patients, and 1 (0.7%) penopubic epispadias patient. A total of 12 (8.2%) BNTs resulted in fistulization, including 4 vesicoperineal fistulas, 7 vesicourethral fistulas, and 1 vesicovaginal fistula. There were 5 (22.7%) fistulas in the cloacal exstrophy cohort and 7 (5.6%) fistulas in the classic bladder exstrophy cohort (P = .019). Using either HAD or native tissue flaps resulted in a lower fistulization rate than using no interposed layers (5.8% vs 20.8%; P = .039). Of those with HAD, the use of a fibrin sealant did not decrease fistulization rates when compared to HAD alone (6.5% vs 8.8%, P = .695). There was no statistical difference in surgical complications between the use of HAD and native flaps (8.6% vs 5%, P = .716). Conclusion Use of soft tissue flaps and HAD is associated with decreased fistulization rates after BNT. HAD is a simple option and an effective adjunct that does not require harvesting of tissues in patients where a native flap is not feasible. |
