Abstract:
1. A method for gastrointestinal anastomosis leak testing, comprising: providing an anastomosis leak tester comprising: submersing the anastomosis in fluid; placing the conduit part in communication with the gastrointestinal tract and directing air into the interior space of the conduit part such that the air flows out of the interior space of the conduit part through the opening of the conduit part into the gastrointestinal tract to thereby distend the anastomosis; continuing to direct air into the interior space of the conduit part until air is caused to pass through the pressure relief valve and moves the indicator pin from the first position to the second position thereby allowing air flow from the pressure relief valve to escape to the ambient atmosphere through the aperture and providing pressure release from the interior space of the conduit part; and then checking for anastomotic leaks based on the presence of air bubbles in the fluid around the anastomosis.
