[Current status and considerations on clinical application of function-preserving pancreatic surgery]

For pancreatic neoplasms, the current clinical treatment strategy is mainly using standard surgical methods, including pancreaticoduodenectomy, distal pancreatectomy with splenectomy, and total pancreatectomy. Standard surgical methods require a larger resection, including resection of some surrounding organs and a large amount of pancreatic parenchyma. The endocrine and exocrine functions of the pancreas are easily damaged. Moreover, since the standard surgical procedure involves the reconstruction of the digestive tract at multiple anastomoses, there is a high risk of pancreatic, biliary, and intestinal fistulas occurring postoperatively. Therefore, function-preserving pancreatic surgery is recommended for some benign and low-grade pancreatic neoplasms. This type of surgery can treat pancreatic diseases while preserving more peripancreatic organs, pancreatic parenchyma and relatively complete digestive tract continuity, thereby improving the patient's short-term and long-term quality of life. In addition, with the development of laparoscopy and da Vinci robotic technology, minimally invasive technology-assisted pancreatic surgery has been carried out in clinical practice. They have been shown to be sufficiently safe and effective. This article reviews several common clinical pancreatic function-preserving surgical methods and their corresponding clinical applications and technical development status from the perspectives of preserving more peripancreatic organs, preserving more pancreatic parenchyma, and promoting pancreatic function recovery.
