Abstract
PURPOSE OF REVIEW: Cystic echinococcosis is a zoonotic infection frequently involving the liver. Treatment options, including surgery, are decided based on the staging of the disease. RECENT FINDINGS: Ultrasound is the cornerstone for diagnosis, staging, and follow-up of cystic echinococcosis. MRI can help to evaluate for cystobiliary complications and planning of the surgery. The two main surgical approaches for cystic echinococcosis include a radical approach, which entails a partial hepatectomy and total pericystectomy, and a conservative approach or endocystectomy. Recent data suggest a conservative approach is well tolerated with acceptable morbidity and no mortality. Recurrences in centers with experience are rare. Data on laparoscopic surgery is emerging, but long-term follow-up still needs to be improved. SUMMARY: Surgical treatment options should be carefully evaluated according to the cystic echinococcosis disease staging. A multidisciplinary approach, including diagnostic and interventional radiology, abdominal and liver surgery, and infectious diseases, results in better outcomes.
