Laparoscopic deroofing of nonparasitic liver cysts. Comparison different methods

Between 1982 and 1995 116 patients underwent operations because of NC of the liver, 18 of them were operated on by laparoscopic way. There were 94 male (mean age: 51.9 years) and 66 female (mean age: 54.6 years) patients. The mean size of the cysts were 57.4 mm in diameter (20-140 mm), In 94 cases they were solitary and in 11 they were multiple. In 31 cases we performed an enucleation, in 60 cases a fenestration and in one case a punction of the cysts. A liver resection had to be carried out in two cases. In 18 cases the fenestration of the cysts was performed by laparoscopy and in 10 cases cholecystectomy was simultaneously carried out. The most common complications were fever and wound suppuration. There was no mortality. Another 26 patients with NC have been treated with ultrasound guided puntion of the liver cysts. The cysts were solitary in twenty-three cases and multiple in three other cases. The number of the cysts were thirty-two. One case had to be operated on because of recurrence of the cyst. Mortality could not be observed. In the laparotomized group the average time of the hospitalisation was 14.3 days, and among the patients who were operated on by laparoscopic way 7.0 days. An intervention is indicated only in case of severe complaints or the growing of the lesion. Recently we prefer the ultrasound guided punction or the fenestration of the liver cysts by means of the laparoscopic way.
