title: Navigation liver surgery for complex hydatid cyst with biliary tree communication.
abstract: BACKGROUND
  Today, liver surgery navigation is utilized only in high-specialized centers for patients affected by malignant diseases. However, navigated surgery may also be of great interest for benign diseases such as hydatidosis in particular if the hydatid cyst is communicating with the biliary tree. With navigation we know exactly in each moment during the surgery the relationship of the cyst with the vascular/biliary structures around it.
  
  
  METHODS
  Herein, we report a case of a 20-year-old W/M affected by hepatic hydatid cyst communicating with the right bile duct, causing recurrent cholangitis. The diagnosis was confirmed by endoscopic retrograde cholangiography and magnetic resonance imaging. The liver cystectomy was easily performed using a navigation system incorporating instrument tracking and three-dimensional CT-reconstruction, thus permitting a selective suture of the bile duct communicating with the cyst.
  
  
  CONCLUSIONS
  The navigated system may guide the surgeon in patients with severe and complicated hydatid cysts.
