Application value of TRIANGLE operation in radical resection of pancreatic cancer

摘要: Objective:To investigate the application value of TRIANGLE operation in radical resection of pancreatic cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 30 patients with pancreatic cancer who underwent TRIANGLE operation in the First Affiliated Hospital of Nanjing Medical University from March 2020 to July 2020 were collected. There were 18 females and 12 males, aged from 41 to 79 years, with a median age of 65 years. After assessment of the resectability and dissection of the hepatoduodenal ligament, the superior mesenteric artery, celiac axis, common hepatic artery, portal vein and superior mesenteric vein of patients were exposed. According to the location of tumor, patients were performed pancreaticoduodenectomy, distal pancreatectomy or total pancreatectomy combined with dissection of putatively tumor-infiltrated lymphatic and neural tissue from the triangular space. During the TRIANGLE operation, it required to at least finish the skeletonization of right semi-circumference of the superior mesenteric artery and celiac axis in cases of pancreatico-duodenectomy, whereas the left semi-circumference in cases of distal pancreatectomy. In principle, both of the superior mesenteric artery and celiac axis were circumferentially skeletonized for cases of total pancreatectomy. Lymphatic, neural and fibrous tissues between the superior mesenteric artery and the celiac artery were completely dissected in all patients. Observation indicators (1) surgical conditions and postoperative histopathological examination;(2) postoperative recovery situations;(3) follow-up. Regular follow-up was …
