Abstract

According to their function, all devices/techniques for liver transection may be classified into two groups: (I) for precise dissection (of the ductal system across the transection plane) and (II) for precoagulation (of the liver parenchymal plane). Precise dissection and precoagulation are two different functions. By using instruments belonging to group I, all vessels/bile ducts along the transection plane can be isolated and dealt with individually so as to achieve precise dissection. By using instruments belonging to group II, the transection plane is precoagulated or prestapled before the transection plane is directly cut into. This may be called blind transection, which is very good for peripheral liver resection yet not good for central liver resection that requires precise dissection. Essentially, all the above-mentioned devices can perform only one of the functions, i.e., either dissection or precoagulation (clip-close the vessels when it comes to the the vascular stapler technique). On the other hand, Peng’s multifunction operative dissector (PMOD) is the only instrument that possesses four functions, beyond the above two functions. Being a versatile device, it is called a multifunction operative dissector. The best aspect of PMOD is that it can delineate all the vessels and ductal system so that the intrahepatic ductal structures can be easily and clearly identified, isolated, and treated individually.
