Influence of the water jet system

Several methods, such as finger fracture, Pean crush, cavitron ultrasonic surgical aspirator (CUSA), and water jet (WJ), are used for hepatic parenchymal dissection in liver surgery. CUSA is the conventional method in Japan. WJ is a relatively novel method for parenchymal dissection. Although it has several advantages, such as lower volume of blood loss and shorter operative time, the effect of the WJ system for hepatic dissection on the remnant liver has not yet been investigated.To investigate and compare the effect of the WJ methodThis observational study compared the two types of parenchymal transection methods (WJOn CT scan, the median areas of denaturation in the liver dissection planes were 522 (range: 109.5-1242) mmThe WJ group had significantly thinner contrast-enhanced areas in the post hepatectomy detached section than the CUSA group.
