[Results of treating liver cysts].

In the years 1974-96, 27 patients aged 31-74 were treated for symptomatic pseudocysts. The duration of symptoms ranged from 3 months to 20 years. Patients were complaining for: pain in the upper abdomen (82%), feeling of fullness (59%), nausea and vomiting (41%), weight loss (23%). Diagnosis was confirmed by USG and CT except of two patients who were diagnosed during emergency surgery because of the cyst rupture. Multiple cysts were present in 4 patients others had single cysts. The treatment comprised: excision of the cyst in 13 patients, excision with partial right lobectomy in 4, fenestration in 5 (laparoscopically in two), marsupialisation of ruptured cyst in one and in remaining 4 puncturing or transcutaneous drainage. Good result of treatment was achieved in all cases. Histologic examination of the cysts revealed: serosal cyst in 18, echinococcal in 2, adenoma originating from bile ducts epithelium in the remaining. The follow up period is 3 months to 21 years. No recurrence of the cyst was noted.
