[Experience with the trans-uterine tubal coagulation with high frequency current and the thermo method under hysteroscopic control (author's transl)].

With the aid of the carbon dioxide hysteroscope, 152 patients underwent transuterine tubal sterilization. 106 women had high frequency current coagulations of the tubes. At follow-up examinations 62 tubes were occluded and 30 showed a unilateral tubal occlusion. These results did not improve by using the thermo coagulation method since only 10 out of 24 patients showed bilateral tubal occlusion and two unilateral tubal occlusions. Up to 20 months following the transuterine tubal sterilization, 28 of the 152 women became pregnant. Of these, 16 became pregnant in spite of hysterosalpingographic evidence of bilateral tubal occlusion. Two patients required emegency laparotomies because of small bowel injuries. Within the coagulation times and temperature ranges used in this series, the results of trans-uterine tubal sterilization are unsatisfactory. It is possible that other types of hysteroscopic tubal sterilizations which are now being developed will be more successful.
