The mortality and morbidity in major hepatic resection is often related to hemorrhage. A high pressure, high velocity water jet has been developed and has been utilized to assist in hepatic parenchymal transection. Sixty-seven major hepatic resections were performed for solid hepatic tumors. The tissue fracture technique was used in 51 patients (76%), and the water jet dissector was used predominantly in 16 patients (24%). The extent of hepatic resection using each technique was similar. The results showed no difference in operative duration (p = .499). The mean estimated blood loss using the water jet was 1386 ml, and tissue fracture technique 2450 ml (p = .217). Transfusion requirements were less in the water jet group (mean 2.0 units) compared to the tissue fracture group (mean 5.2 units); (p = .023). Results obtained with the new water dissector are encouraging. The preliminary results suggest that blood loss may be diminished.
肝大部切除术中的死亡率和发病率常与出血有关。一种高压、高速水刀已被研发出来，并用于辅助肝实质离断。对67例肝脏实性肿瘤患者实施了肝大部切除术。51例患者（76%）采用了组织破碎技术，16例患者（24%）主要使用了水刀分离器。两种技术的肝切除范围相似。结果显示手术时间无差异（p = 0.499）。使用水刀的平均估计失血量为1386 ml，组织破碎技术为2450 ml（p = 0.217）。与组织破碎组（平均5.2单位）相比，水刀组的输血需求量较少（平均2.0单位）；（p = 0.023）。新型水刀分离器取得的结果令人鼓舞。初步结果表明失血量可能会减少。
