Method and system for detecting leaks and/or verifying adequate closure following a medical procedure

摘要

Method for detecting leaks and/or verifying adequate closure following a medical procedure, on a hollow or tubular organ of a subject, wherein a leak test is performed by injecting or insufflating, in the concerned organ, a specific test gas which is not commonly produced or naturally present within the body of the subject, or which is present or produced in a precisely known amount or concentration, and by analyzing percutaneously the gas or gas mixture present locally within the body cavity in which the organ is situated, and then verifying the presence, and preferably determining the concentration, of the injected or insufflated test gas in the local gas or gas mixture of the body cavity and indicating whether the concerned organ or a lumen defined by the latter is leak-free or not.
