Macroscopic and microscopic studies of fallopian tube after laparoscopic sterilization.

Histological study was carried out on human fallopian tubes one hour and one month after various methods of laparoscopic sterilization. Ciliated cells were counted and histological lesions were observed. Deciliation is proved at a distance from the site of sterilization. Taking into account these two data, it has been possible to display the substance loss provoked by each of the usual sterilization methods (unipolar electro-coagulation, bipolar electrocoagulation, silicone ring and Hulka-Clements clip) which have to be taken into consideration in case of surgical re-anastomosis.
