The excellent results experienced with the use of seromuscular intestinal grafts in certain types of urological plastic operations encouraged us to use it (as a patch) also in the surgical management of vesicovaginal and rectovaginal fistulas. With this method, we treated 4 patients with post-irradiation fistulas who had previously undergone 1 or 2 operations. The seromuscular intestinal graft served as a direct partial wall replacement of the bladder or rectum. At the same time, it also supported the nutrition of the compromised tissues surrounding the fistula. There were no complications with epithelialization of the denuded muscular surface of the seromuscular intestinal graft (patch) facing into the bladder.
As demonstrated in animal experiments and in five patients with atonic bladders, "vesical cap" surgery causally solves detrusor impairment by functionally reinforcing it with a vital muscle layer from an ileal seromuscular flap. All other genuine components of the bladder are kept intact, which is very beneficial for bladder function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
