Laparoscopic sutured anastomosis of the bowel

Background: Even though the safety and efficacy of sutured anastomosis have been proved in open surgery, laparoscopic sutured anastomosis is rarely performed because it is difficult and time-consuming. We aim at description of a standardized technique for laparoscopic sutured anastomosis of the bowel and definition of its learning curve. Methods: Fifty-six laparoscopic sutured anastomoses of cow small intestine were performed in a laparoscopic simulator. In a survival animal trial, 10 end-to-end, 2 gastrojejunostomy, 2 cholecystojejunostomy, 2 colocolic, and one side-to-side anastomoses were performed, using the same technique. Results: In the survival cases, we had no leaks or obstruction, minimal adhesions, and only one stenotic gastrojejunostomy. The mean end-to-end anastomotic time was 50 min. The technique was suitable for most sites in the GIT. The learning phase required 40 anastomoses in the simulator. Conclusions: The described technique seems relatively fast, safe, and universal, and it needs about 40 anastomoses to be mastered.
