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

Abstract

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.

Symptomatic giant solitary bile cyst with intracystic bleeding in a 13-year-old girl: a case report and literature review

“…It had welldefined limits, encapsulated, regular contours, heterogeneous content of cystic predominance, and no evidence of calcifications or fats inside. The estimated size and volume were 25 cm × 22 cm × 12.5 cm and 3595 cm 3 , respectively. At magnetic resonance imaging (MRI) of the abdomen, the lesion presented predominantly high signal intensity on T2-weighted sequences, with heterogeneous hypersignal content on T1-weighted sequences, with no evidence of contrast enhancement, suggesting cystic lesion with hematic content due to intracystic bleeding.…”

“…Simple hepatic cyst is a congenital biliary malformation, its origin is derived in aberrant bile ducts that have lost communication with the biliary tree and continue to secrete intraluminal fluid [1,2]. Numerous terms have been used to designate this cystic lesion in the literature, including biliary cyst, nonparasitic hepatic cysts, benign hepatic cyst, congenital liver cyst, unilocular cyst of the liver, and solitary liver cyst [1,3]. They occur in the general population with a prevalence of up to 5% and are increasingly diagnosed due to the increased use of imaging methods [3][4][5].…”

They occur in the general population with a prevalence of up to 5% and are increasingly diagnosed due to the increased use of imaging methods [3][4][5]. Female-to-male ratio is 1.5:1 for all simple cysts shown at imaging or necropsy, while for symptomatic or complicated simple cysts is 9:1 [2].…”
