[Incidence distribution of postoperative adhesions after using different coagulation techniques. An animal experiment...

This study compares the incidence of adhesions after using the Endocoagulator by Semm with the incidence of adhesions after using the Nd-YAG-laser with 30 watts and 100 watts. At a total of 100 female Wistar-rats both, the uterine-horns and 2 correspondent spots at the ventral abdominal-walls were coagulatet. resp. vaporized. After 14 resp. 28 days a relaparotomie was made: 1. With the Nd-YAG-laser (30 and 100 watts) (significant) adhesions were found, at the uterine-horns in 100% of all cases with the Endokoagulator in 50%. At the peritoneal spots with the Nd-YAG-laser (30 and 100 watts) (not significant) adhesions were found in 10% of all cases, with the Endokoagulator 5% were found. 2. In addition to the macroscopic results histologic researches were also made: It was shown, that the treatment with Nd-YAG-laser develops a high grade of carbonisation-waste, which is known to be a main cause for the development of adhesions. 3. The division in 14- and 28-day-groups showed no significant differences in the incidence of adhesions. 4. There were found more significant adhesions at the uterine-horns than at the peritoneal-spots.
