Our experience in liver resection with intra-operative and laparoscopic ultrasound: Interest of ultrasonic shears for parenchymal transection

Objectives: Careful staging of hepatic tumors is mandatory for appropriate selection of patients for liver resection. Number and relationships of liver nodules are issues of utmost importance when evaluating resectability. Sensitivity of pre-operative imaging for secondary lesions has been reported between 60–75% with spiral contrast enhanced CT, 80–85% with MRI, 90–96% with intra-operative ultrasound (IOUS). Also for primary lesions IOUS has been reported to allow detection of further nodules in 17% and modify surgical strategy in 10%. The aim of this presentation is to point out the usefulness of open (IOUS) a…
