End-to end colorectal anastomosis with the ColonRing is feasible and safe procedure with fast learning curve. To date, this type of anastomosis is possible in left sided colon lesions where anastomosis is contemplated below the promontory. We find the device easy to use with high level of confidence. Further prospective studies including comparison between the ColonRing device and the conventional staplers evaluating long-term anastomotic complications (i.e., leak or stricture) are needed to evaluate the benefits and limitations of this device.
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.
