NONPARASITIC LIVER CYSTS - LAPAROSCOPIC A ND CONVENTIONAL FENESTRATION

From 1992 till 1997 10 patients with solitary nonparasitic liver cysts were treated by laparoscopically fenestration of the cysts. The size of the cysts varied between 8 and 16 cm (median 13.5). Conversion to l aparotomy tvas required in one patient because of intraoperative bleed ing. In nine patients the laparoscopic procedure was finished successf ully. In these cases we observed no intraoperative complications (9/10 ), intraoperative blood loss amounted up to 100 ml. Median operative t ime amounted to 82,5 minutes (55-155). No postoperative complications were observed. In two patients a cystadenoma was proven by postoperati ve histology, in both cases a liver resection was performed. During a median follow-up of 33 (2-43) months 2 of 7 patients treated with lapa roscopically fenestration developed a recurrence (28 %).
