Comparison between tubouterine implantation and tubouterine anastomosis for repair of cornual occlusion.

Forty-four patients with partial or complete cornual occlusion of their tubes had undergone microsurgical repair in the form of either tubouterine implantation or tubouterine anastomosis. Eighteen of these patients had undergone the implantation procedure and 26 the anastomosis procedure. None of the patients in the implantation group had previous tubal sterilization, while in the anastomosis group 16 had tubal cauterization and 10 had other causes blocking the cornual end of their tubes. The patency rate in the implantation group was 70% and the pregnancy rate was 39%, while in the anastomosis group the rates were 94% and 69%, respectively. It is concluded that, when feasible, tubouterine anastomosis should be the procedure of choice for the repair of the cornual occlusion of the tube irrespective of the cause of obstruction.
