An experimental model for pelviscopic tubal anastomoses

An endoscopic technique for tubal anastomosis has been developed in a rat uterine horn model. Uterine segments were anastomosed endoscopically in a training device for surgical pelviscopy ('Pelvitrainer') by fibrin glue, using an inlaying splint as a guide. The anastomoses were accomplished by a seromuscular 6-0 suture at the anti-mesenteric border. Morphological studies revealed good patency of the anastomosed segments without stenoses or occlusions. The tissue continuity was good. In only two cases out of the 20 studied was a tapering of the uterine wall found adjacent to the anastomosis. It is concluded that this endoscopic technique for tubal anastomosis presents a useful alternative to classical microsurgical reversal of sterilization by laparotomy.
