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.
