Abdominal wall closure in adult patients with untreated exstrophy of bladder

Bladder exstrophy is an anomaly, which if not treated early in the age, poses a surgical challenge in providing an adequate abdominal wall closure. We report our experience in patients with untreated exstrophy of the bladder, who underwent cystectomy, ileal conduit, and abdominal reconstruction using the anterior rectus sheath turndown flap and paired inguinal skin flaps.

Ten previously unoperated adult patients with exstrophy with epispadias, who underwent surgery at our institute from January 2010 till January 2021, were included in this study to evaluate the adequacy of abdominal wall closure with our technique of retrograde turndown anterior rectus sheath flap with paired inguinal flap, and to document immediate and delayed complications, especially incisional hernia.

The mean follow-up period of the study was 16.5 months. We found that our technique provided adequate local tissue for a sturdy two-layered closure of the lower abdominal wall defect. Out of the ten patients, only one required an additional flap for abdominal wound closure. There were no stoma-related complications or incisional hernia.

Abdominal wall reconstruction, for skin and fascial defects, in such complex cases can be performed by local skin and fascia using a relatively simple, safe, easy, and affordable technique as we have described. Our technique avoids the use of synthetic mesh, thereby reducing the chances of infection in such chronic open wounds.
