[Complications and psychosomatic problems after tubal sterilization].

From 1969 to 1974, 2080 patients were sterilized, 1702 by the pelviscopic method (electrocoagulation), 375 by laparotomy, and 3 vaginally. About two thirds of the sterilisations by laparotomy were carried out after delivery or during other surgical procedures. 15% of all women were sterilized for medical reasons; the other cases had to be 35 years of age or at least 30 if they had more than 3 children. The overall complication rate was 5% with both methods. Complications during pelviscopy included hemorrhage, bowel injury and burns. Postoperative complications after laparotomy were hemorrhage, thrombosis and wound dehiscence. Only half of the patients could be followed up; there were 4 pregnancies among 1308 women. In more than 50% the sexual relations had improved, in only 3% they had worsened. About 97% of the pelviscopically sterilized patients were satisfied with surgical method chosen and with their present status. It is recommended to allow sufficient time to think the decision over prior to the operation.

Radio frequency leakage current from unipolar laparoscopic electrocoagulators.

Radio frequency (RF) leakage current has been suspected of causing accidental tissue burns associated with laparoscopic electrocoagulation used for tubal sterilization. A study was done to determine the levels of capacitively coupled RF leakage current from six unipolar laparoscopes manufactured by five companies. Leakage current values ranging from less than 100 mA to over 550 mA were measured at electrosurgical unit power settings of up to 150 w into 1,000 ohms. These levels represent 24-62% of the total electrosurgical current generated by the electrosurgical units. Using a criterion for tissue injury of 100 mA/sq cm applied for ten seconds, leakage current levels exceeding 400 mA are capable of producing burns either at the abdominal wall or to internal organs that accidentally come into contact with the body of the laparoscope. One of the six devices tested had leakage current levels higher than 400 mA at power settings lower than 100 w. Capacitance measurements between the unipolar laparoscope body and the forceps ranged from 53 to 140 picofarads.

The bipolar needle for vasectomy. I. Experience with the first 1000 cases.

A battery-powered, bipolar electrocoagulator has been specifically developed for sealing the cut ends of the divided vas at vasectomy. With a minimum of electric power, the electrocoagulator destroys only the mucosa and one or two muscle cell layers of the vas, which leads to optimal fibrosis of the cut ends. This instrument has been used in more than 1000 vasectomies without a known failure and with a minimum of complications. An analysis of these cases is reported with emphasis upon the method's success in sealing the vas.

Evaluation of ovarian function after tubal sterilization.

Many women appear to experience menstrual disturbances after tubal sterilization. In this study the ovarian function in such women was investigated. Serial measurements of FSH, LH, estradiol and progesterone were performed throughout the study cycle in 23 previously sterilized patients, 14 with menstrual disturbances (group I--symptomatic) and 9 with normal cycles (group II--asymptomatic). A group of 28 parous women served as controls. Among 23 patients, luteal phase progesterone was elevated in 19, and in 4 it was undetectable (anovulatory). All four anovulatory patients belonged to group I. Anovulatory cycles were also characterized by tonic elevated LH levels. Mean midluteal progesterone values were lower in group I (8.5 ng/ml) than in group II (13.8 ng/ml) and in the controls (16.5 ng/ml). Mean midluteal progesterone was lower than 10 ng/ml in 78% of group I, 44% of group II and 15% of the control patients.

[Microscopic study of human fallopian tubes after laparoscopic sterilization (author's transl)].

Histological study was carried out on human fallopian tubes one hour and one month after various methods of laparoscopic sterilization (unipolar electrocoagulation, bipolar electrocoagulation, silicone ring and Hulka-Clemens clip). Microscopic lesions were observed. Ciliated cells were counted. Deciliation is proved at a distance from the site of sterilization. It has been possible to display the substance loss of the tubal tissues which have to be taken into consideration in case of surgical reanastomosis.
