Clinical Trial Summary

LLR was applied for tumors located at the lower edge and lateral segments of the liver that could be resected more easily than posterosuperior segments. With the development of technology and the growing experience of hepatobiliary surgeons, LLR has been expanded to major liver resections, anatomical resections, and donor hepatectomies by skilled surgeons. However, postoperative mortality, mobility and recovery of liver function are associated with major blood loss which is always the main cause of conversion to laparotomy and remains a challenge for surgeons. Pringle first described the method to arrest the hepatic hemorrhage by compression of the porta hepatis and this procedure was widely spread as well as in laparoscopic feild currently. Here, we described a new modified of Pringle maneuver using Bulldog to block vascular during LLR, and compared its effects with traditional pringle maneuver.


Description:

With the innovations of laparoscopic technique and specialized equipment , laparoscopic liver resection became the dominating resection surgery approach. December of 2014, laparoscopic hepatectomy was carried out in our department, extracorporeal Pringle maneuver has been applied in most laparoscopic liver resections which need to block the hepatic inflow, cotton tape was the frequently used tourniquet. We used to blocked the hepatic inflow by extracorporeal Pringle maneuver method with cotton tape for its validity , softness and no visible damages for vessel, but it was always difficult for clamping in a two-dimensional view to encircle the hepatoduodenal ligament , and it delayed operation time for freshmen. Bulldog has been widely used in urinary surgery for vascular occlusion, but bulldog in hepatic surgery has rarely been mentioned, this is the first report to formally demonstrate the clinical application in hepatic surgery. However, it is not clear that whether the bulldog for vascular occlusion is useful and easy to implement in laparoscopic hepatectomy. In this study, we will compare the cotton and the bulldog for vascular occlusion during laparoscopic hepatectomy
