The cervical polyp: a new diagnostic and therapeutic approach with CO2 hysteroscopy.

CO2 hysteroscopy for diagnosis of cervical polyps was performed in 36 patients. The polyps could be located under direct vision and their attachments were found to be deeper than what is seen in regular inspection. A relatively high number of endometrial polyps were found. It is advised that the polyps be surgically removed by cutting the stem at its attachment followed by a curettage.

Tissue-puncher and loop-ligation--new aids for surgical-therapeutic pelviscopy (laparoscopy) = endoscopic intraabdominal surgery.

The optimal development of the pelviscopic instruments for diagnostic purposes provides us with the start in the field of surgical therapeutic pelviscopy. Newly developed instruments: Loop ligation-applicator, Tissue-Puncher (morcellation-forceps), Aqua-Purator and the new CO2-PNEUS-AUTOMATIC (S = security) have enabled us to replace some of the prior operations requiring classic gynecologic laparotomy with surgical-therapeutic pelviscopy: Ovarectomy, adnectomy, myomectomy, cystectomy, resection of the tube-pregnancy. After more than 2,200 smaller surgical interventions were performed successfully since 1973 via pelviscopy with the hemostasis aided by 100 degrees C destructive heat (Endocoagulatory, Crocodile-Forceps and Point-Coagulator) more than 50 ovarectomies etc, could be performed in 1977 via pelviscopy without intra- or postoperative complications.

[Postpartum contraception: effect of lynestrenol during the lactation period (author's transl)].

167 women were treated with 0.5 mg lynestrenol/day for a period of 8-32 weeks immediately postpartum. The lactation periods of 67 of the women were observed during the stay in hospital (maximum 7 days) in comparison with a control group (n = 20) of untreated women in the puerperium. There was no quantitative difference in milk production between the lynestrenol-treated women and the control group. In order to exclude a possible thromboembolic effect the lynestrenol the thrombocyte aggregation was determined in all women at 4-weekly intervals as a measure of a thrombotic tendency. During the entire period of the investigation the mean PAT rating remained between I and II. Among the clinical parameters a raised amenorrhea rate of 21% and a larger proportion (39%) of breakthrough bleedings were notable. The responded easily to treatment.

Hysteroscopic sterilization--a routine method?

Our intention was to sterilize 50 women by means of hysteroscopic sterilization, and we were unsuccessful in 60% of these cases. All these women ran the risk of another pregnancy with hysteroscopic sterilization alone. Therefore--in our opinion--the method of hysteroscopic sterilization by thermocoagulation of the intramural part of the tubes is not yet a routine method, at least not before another modification of this method or instruments makes it possible to obtain better results.

Endocoagulation: a new and completely safe medical current for sterilization.

Tubal sterilization via pelviscopy with low current represents a unique method: the risk of high-frequency is thereby eliminated, and the application of the Crocodile-Forceps is relatively simple. The mouth of the Crocodile-Forceps grasps the tube under pelviscopic control. Tubal coagulation succeeds under electronic control at 100 degrees C and the area of coagulation measures 6-8 mm in length. In case additional separation of the tube is desired it may be performed bloodlessly with a scissor-like movement. The Crocodile-Clamp is electronically monitored by the "Tube-Coagulator" or the universal endoscopic "Endo-Coagulator." Since 1973 964 tubal coagulations by means of cutting have been performed without postoperative hemorrhage or other complications (pregnancy rate 0).

[Two-phase respiration of apnoeic newborn, basic research and clinical value (author's transl)].

Studies on fetal human and calf lungs proved an 1: 2,5 increase rate of the transpulmonary blood-flow after inflation of the alveolar spaces. The extent of the inflation depends on the function pressure X time. Based on the rupture rate of the pulmonary tissue, the factor pressure is limited to 20-30 ch H2O. Consequently the inflation only can be obtained by increasing the factor time. Conditional on the flow resistance in the variably calibrated branches of the pulmonary system, the maximal pressure of 30 cm H2O has to act repeated continuously at least 10 seconds over an endotracheal tubus. Only then even the periphere alveoles will fully be inflated (phase I equals monotone inflation phase). An intermittend pressure breathing of maximal plus 30 cm H2O respectively-30 cm H2O will be supporting. After the total inflation short pressure waves of plus 30 cm H2O in physiological frequency (equals 30/minute) will do for further ventilation of the alveoles (phase II equals rhythmical ventilation phase).

[Microsurgery in gynaecology: endocoagulation, a new method for operations in pelvic endoscopy (author's transl)].

Hemostasis by high frequency current in the abdomen is too dangerous during pelvic endoscopy. Pelviscopy was therefore mainly a diagnostic procedure. Modern electronic coagulation instruments such as the Crocodile forceps and the point coagulator today permit the application of destructive heat without electrical risk for the patient in the peritoneal cavity. The electronic monitor for this coagulation instrument, the endocoagulator gives an optical and acoustical record of the coagulation temperature. The endocoagulation technique permits reorientation of gynaecological surgery to a new micorsurgical technique. Operations for sterilization the lysis of adhesions, the treatment of endometriosis and ovarian cysts in young people reduces the need for laparotomy by 40 to 50% when modern endocoagulation is used. Endocoagulation can now be recommended as routine technqiue for every pelvic endoscopic operation. In 2715 pelvic endoscopies, destructive heat was used in 47% of the cases and the complication rate was 1.3%.

[Pelviscopic surgery in gynaecology (author's transl)].

Surgery of the fallopian tubes has today developed into pelviscopic surgery. The development of suitable instruments such as the tube set, a new endocoagulation method were prerequisites for this development. Operative therapeutic pelviscopic surgery is a development past laparotomy. It is now possible to treat adhesions in the abdomen with this method, to coagulate and divide fallopian tubes for sterilization, to aspirate ovarian cysts and resect walls of ovarian cysts, to coagulate endometriosis and to perform salpingolysis and salpingostomy. In selected cases ovariectomy and myomectomy are possible through the pelviscope. Tables and statistics on 3300 pelviscopies are presented. The indications are discussed. The use of pelviscopy following previous laparotomy (1831 cases) is discussed. The complication rate was 1.10% without death, without injury to large vessels, without embolic phenomenon. The operative risk is therefore less than that of laparotomy. The operative therapeutic pelviscopy can replace the classical laparotomy in about 25% of the cases. For the operation of tubal infertility, a laparotomy is eliminated in about 80% of the cases.

Results of diagnostic pelviscopy in cases of chronic recurrent pelvic disease.

During the last two years we have performed diagnostic pelviscopy in 90 patients suffering from a syndrome of chronic repeated pelvic disease. In 44 patients extragenital endometriosis was diagnosed as the causing factor. In 15 cases we found wide-spread adhesions in the region of the lower pelvis after preceeding laparotomies. Only in 12 patients pelvic-alterations caused by chronic inflammatory processes of the adnexa with peritubal adhesions were discovered. As these results show extragenital endometriosis represents in far more cases as generally believed the cause of gynecological pains. We want to give special emphasis to the diagnosis and treatment of this disease.

Endocoagulation: a new filed of endoscopic surgery.

Pelviscopy was predominantly concerned with diagnostic procedures until recent years. Modern electronically controlled coagulation instruments, such as the crocodile forceps and the point coagulator, permit the application of destructive heat without any risk of electric current within the abdominal cavity. The electronically regulated apparatus for these coagulation instruments is the Endo-Coagulator, which indicates the coagulation temperature optically and acoustically. The endocoagulation technique opens a new area of operative gynecology. In the field of sterility operations, adhesion cuttings and the treatment of endometriotic and juvenile ovarian cysts, the application of modern endocoagulation has reduced the frequency of laparotomy by about 30% to 40%.
