    Abstract:
    BACKGROUND: The high incidence of anastomotic stenosis after gastrointestinal surgery using circular staplers is a major problem. In response, we have developed a new technique that uses a linear stapler to enlarge an anastomotic opening made using a circular stapler. METHODS: Anastomoses were created by the new technique or by the conventional approach using a circular stapler in pig small intestine. The method was also applied in treatment of a colon cancer patient. RESULTS: The area of the anastomotic opening obtained with the new technique was more than 3 times that in the control (p < 0.001), with no significant difference between the methods in a leak test. Follow-up of the patient undergoing surgery with this approach revealed an uneventful course with a widely patent anastomosis confirmed after 3 months. CONCLUSIONS: This procedure provides a larger anastomotic opening than conventional anastomosis with circular staplers, without impairing the integrity of the anastomosis.
