Introduction:
Bladder exstrophy (BE) is a rare, complex malformation. There are three major approaches to closure. Despite this choice, abdominal wall closure in such patients is usually a challenging procedure specially in large defects and redo cases.
Objective:
Our aim is to present our ten first cases' results, using Anterior Component Separation (ACS) to abdominal wall closure in BE patients.
Study Design:
Ten male patients with BE (median age 7 months, range from 3 to 24 months) were operated from March 2020 to March 2021 by a multi-institutional Brazilian group using the Kelly technique. In addition to BE correction, anterior component separation was performed for abdominal closure.
Results:
Postoperative suprapubic fistulae occurred in two of ten patients, but both closed spontaneously. No evisceration, abdominal wall dehiscence, or herniation was observed at a mean follow-up time of 14 months (range from 10 to 22 months). A 3 cm extent of advancement is achievable upon traction in each side (Fig. 3).
Conclusion:
We proposed the use of anterior component separation as an alternative for abdominal closure after BE correction using the Kelly procedure. This new technique avoids mesh usage, loosens the abdominal wall tension, and reduces complications. Even However, further studies are required.
