Laparoscopic Surgery in Nonparasitic Cysts of the Liver: Results Observed in a Series of Consecutive Cases.

The purpose of this study was to report the results of laparoscopic treatment of nonparasitic cysts of the liver (NPCL) in terms of postoperative morbidity (POM) and recurrence. Prospective case series of patients operated on for NPCL at the Clínica Mayor in Temuco, Chile (2008 to 2015). The preoperative study consisted of general examinations, abdominal ultrasound or computed tomographic scan. The outcome variable was POM. Other variables of interest were surgical time, need for conversion, hospital stay, mortality, and recurrence. In the study period, 41 patients with NPCL underwent surgery. Median age of the series was 58 years, and 75.6% of the cases were female. The median ultrasound diameter of the lesions was 10 cm and surgical time was 50 minutes. All patients underwent a cystectomy. There was no conversion, no record of POM, mortality or recurrence. The treatment applied in this series of NPCL is associated with an adequate postoperative evolution.
