RESUMEN

INTRODUCTION: To decide treatment of hepatic cysts diagnosis between simple hepatic cyst (SHC) and cystic mucinous neoplasm (CMN). Radiological features are not patognomonic. Some studies have suggested the utility of intracystic tumor markers. METHODS: Retrospective analysis of our prospective database including patients treated due to symptomatic SHC from 2003 to 2021. The aim of the study was to evaluate the results of treatment of symptomatic SHC and the usefulness of the determination of intracystic "carcinoembryonic antigen" (CEA) and "carbohydrate antigen" CA 19.9. RESULTS: 50 patients diagnosed and treated for symptomatic SHC were included. In 15 patients the first treatment was percutaneous drainage. In 35 patients the first treatment was laparoscopic fenestration. Four patients were diagnosed of premalignant or malignant liver cystic lesions (MCN, IPMN, lymphoma B); three of them required surgery after initial fenestration and pathological diagnosis. Median CEA and CA 19-9 were 196 µg/L and 227.321 U/mL respectively. Patients with malignant or premalignant pathology did not have higher levels of intracystic tumor markers. Positive predictive value was 0% for both markers, and negative predictive value was 89% and 91% respectively. CONCLUSION: Values of intracystic tumor markers CEA and CA 19-9 do not allow distinguishing simple cysts from cystic liver neoplasms. The most effective treatment for symptomatic simple liver cysts is surgical fenestration. The pathological analysis of the wall of the cysts enables the correct diagnosis, allowing to indicate a surgical reintervention in cases of hepatic cyst neoplasia.

RESUMEN

The advent of enhanced radiological imaging techniques has facilitated the diagnosis of cystic liver lesions. Concomitantly, the evidence base supporting the management of these diseases has matured over the last decades. As a result, comprehensive clinical guidance on the subject matter is warranted. This guideline covers the diagnosis and management of hepatic cysts, mucinous cystic neoplasms of the liver, polycystic liver disease, caroli disease, caroli syndrome, biliary hamartomas and peribiliary cysts. On the basis of in⁃depth review of the relevant literature, this guideline provides recommendations to navigate clinical dilemmas followed by supporting text. The recommendations are graded according to the Oxford Centre for Evidence⁃based Medicine system and categorized as "weak" or "strong". This guideline aims to provide the best available evidence to aid the clinical decision⁃making process in the diagnosis and treatment of patients with cystic liver diseases, and presents the readers with translations and summarizations of the above mentioned recommendations.
