Total lumpectomy pancreaticoduodenectomy (TLPD) Tips: 1. Strictly grasp the surgical indications, for duodenal tumors, peri-potty cancer and early pancreatic head tumors, performing total lumpectomy pancreaticoduodenectomy is technically feasible; 2. Reconstruction is the difficult point of the whole operation. For pancreatic-intestinal and biliary-intestinal anastomosis, intracavitary continuous suturing with knot-free sutures can be considered, which can significantly shorten the operation time, and gastrointestinal anastomosis is relatively simple, and Endocutter conventional anastomosis can be chosen.
