[Tube-preserving endoscopic surgical procedures in unruptured tubal pregnancy. What significance does laser use have?].
Between 1985 and 1989 115 non-ruptured tubal pregnancies were operated upon, using a pelviscope and preserving of the tube. For the purpose of prophylactic haemostasis 2,5 I.U. ornipressin (Por 8) were injected into the mesosalpinx. The tube was opened (linear salpingotomy) by using various instruments. This method was used in 49 patients by means of the thermocoagulator and hooked scissors; with the remaining 66 patients the following laser systems were employed: CO2-laser (n = 13); Nd: YAG-laser by the contact method (n = 22); argon-laser (n = 31). No intraoperative complications were noted. Postoperative rebleeding occurred in three patients requiring subsequent treatment, and pelviscopy had to be repeated in two patients, because of incompletely removed trophoblastic tissue. The tubal condition (patency; occurrence of adhesion) was checked in 53 (47%) of the patients by means of hysterosalpingography (n = 15) or second-look pelviscopy (n = 38). Tubal patency/peritubal adhesion were found after conventional surgery in 64%/55% of the controlled cases and after laser salpingotomy in 90%/11%, respectively. Summing up, we can say, that the various laser systems are suitable for operating non-ruptured pregnancies due to their accurate incision and simultaneously coagulating effect. Due to the lower postoperative tubal occlusion rate and lower tendency to adhesion, it appears, that the laser systems are superior to the conventional endoscopy instruments, although the rate of complications was highest after CO2-laser application.
