Following the invention by Hans G. Beger of the procedure of duodenum-preserving pancreatic head resection (DPPHR) combined with Roux-en-Y pancreatic–enteral reconstruction for chronic pancreatitis in 1972, a singlecenter 26-year experience of how DPPHR changed the natural course of the disease and affected shortand longterm clinical efficacy was analyzed and evaluated by Beger in 1999. The results included low incidence of postoperative complication and mortality as well as the advantages of maintaining the endocrine and exocrine functions of the pancreas and high remission rate (91.3%) of abdominal pain. Three prospective randomized controlled studies showed that DPPHR had significantly better short-term clinical efficacy compared with pancreaticoduodenectomy, which was also a conventional surgical procedure for chronic pancreatitis. Moreover, DPPHR offered the obvious advantages of stomach, duodenum, and biliary tree preservation, high long-term quality of life, and good exocrine functions. With the rapid progress in laparoscopic pancreatic surgery over the last decade, laparoscopic duodenum-preserving pancreatic head resection (LDPPHR) still remains a challenging surgery due to the requirement for complicated pancreaticojejunostomy (PJ) and ensuring sufficient blood supply to the duodenum and common bile duct (CBD) and their preservation.
