The surgical treatment of chronic pancreatitis, benign, borderline and low-grade malignant tumors of the pancreatic head is definite in effect. How to preserve more functional organs is the focus of such surgeries. The duodenum, common bile duct and Oddi’s sphincter-preserving pancreatic head total resection (DCOPPHTR) surgical method pioneered by the author team has theoretical advantages compared to other surgical methods. However, due to the difficulty of surgical operation and higher requirements for surgeons, its widespread application is limited. By elaborating on the invention principle and evolution process of this surgery, analyzing the key steps in detail and showing the clinical effects, the author proves that DCOPPHTR is safe and effective and has higher clinical application value.
