The current study aimed to evaluate the therapeutic features and complications of liver hydatid cyst in patients who underwent surgery for CE in Fars province, southern Iran.

A total of 293 patients who underwent surgery for liver hydatid cyst from 2004 to 2018 in Fars Province, southern Iran, were retrospectively evaluated. The clinical records of patients were reviewed and the demographic and clinical characteristics of each patient were assessed.

Fars province with the capital of Shiraz in one of the thirty-one provinces of Iran located in the southwest part of the country with a population of more than 4.6 million people of which 67.6% living in urban areas, 32.2% in rural areas and 0.3% live as nomad tribes.
