Resection and primary anastomosis should be the treatment of choice for colovesical fistulae, with an acceptable risk of anastomotic leak and mortality. Barium enema, colonic endoscopy and CT should be routine in the investigation of colovesical fistulae.
These results suggest that movement of cells throughout the peritoneal cavity during laparoscopy is via contaminated instruments, but local cell movement by dispersion possibly within water vapor from the port may also occur.
Patients who develop cardiac symptoms following restorative colorectal resection for carcinoma should have a water soluble enema as there is a 40% chance that they will have an anastomotic leak.
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.
