Study population: Patients with liver hydatidosis carried out at our Hepato-Pancreato-Biliary Surgery Unit

Brief summary: Cystic echinococcosis is a clinically complex chronic parasitic disease and a major socioeconomic problem in endemic areas. The safety of liver resection in elderly patients is often debated among medical professionals. The investigators analyzed the postoperative morbidity and mortality rates of elderly patients who underwent surgery at our unit.

Detailed description: Retrospective observational study from prospective database focused on liver hydatidosis carried out at our Hepato-Pancreato-Biliary Surgery Unit. The study period spanned from January 2006 to October 2020. The study was approved by the Research Ethics Committee of our hospital. An informed consent from the patient was not required since the study was retrospective and observational, and entailed no risk. Seventy years of age was the cutoff age to consider patients as elderly.

Inclusion criteria of patients: liver hydatid cyst (LHC) diagnosed by preoperative computed tomography (CT) or magnetic resonance imaging (MRI) and pathological diagnosis after surgery, and LHC treated by total or partial pericystectomy.

Exclusion criteria of patients: emergency surgery and simple drainage of cyst.

Eligibility criteria: Inclusion Criteria:

* liver hydatid cyst (LHC)
* pathological diagnosis after surgery
* LHC treated by total or partial pericystectomy

Exclusion Criteria:

* emergency surgery and simple drainage of cyst
