ObjectiveTo explore the application value of “enfolded pancreatic duct”pancreaticojejunostomy (PJ) during laparoscopic pancreaticoduodenectomy (LPD). MethodsThe clinicopathologic data of patients underwent LPD and “enfolded pancreatic duct” PJ from May 2020 to March 2022 were collected retrospectively. The time of PJ was recorded. And the pancreatic leakage, biliary leakage, chyle leakage, bleeding and infection, and death within 30 d after the operation were observed. ResultsA total of 132 patients were collected, including 60 males and 72 females. The age of patients was (58.6±10.9) years old. There were 38 cases of pancreatic head cancer, 17 cases of duodenum carcinoma, 17 cases of inferior segment cholangiocarcinoma, and 23 cases of duodenal papilla carcinoma, 7 cases of pancreatic neuroendocrine tumor, 11 cases of pancreatic intraductal papilloma, 5 cases of duodenal stromal tumor, 5 cases of duodenal papillary adenoma, 6 cases of pancreatic cyst adenoma, and 3 cases of pancreatic head stone. None of the patients was converted to open surgery. The diameter of pancreatic duct before operation was (3.43±2.11) mm, which were <3 mm in 31 cases. The time of PJ was (20.61±3.16) min. The pancreatic leakage occurred in 17 cases, including 11 cases of grade A leakage, 6 cases of grade B leakage, and none of grade C leakage. There was 1 case of bile leakage, 6 cases of chyle leakage, 5 cases of postoperative bleeding (2 cases of intraabdominal bleeding and 3 cases of gastrointestinal anastomotic bleeding), 3 cases of intraabdominal infection, and no death. None of the patients was readmission due to complications after 90 d of follow-up. ConclusionsFrom summary results of this group of cases, compared with the traditional PJ method, “enfolded pancreatic duct” PJ is less difficult and simpler to operate, which can obviously shorten the PJ time during LPD and reduce the incidence of pancreatic leakage. It is especially suitable for laparoscopic application.
Objective To analyze the difference in the incidence of postoperative pancreatic leakage and anasto-motic bleeding complications in various methods of pancreaticojejunostomy after pancreaticoduodenectomy （PD）. Methods The clinical data of 526 patients underwent pancreaticojejunostomy from January 2008 to September 2012 in this hospital were analyzed retrospectively. End-to-side “pancreatic duct to jejunum mucosa-to-mucosa” anastomosis （abbreviation：mucosa-to-mucosa anastomosis） was performed in 359 patients， which contained 149 patients with internal drainage， 130 patients with external drainage， and 80 patients with no drainage. End-to-side invaginated anastomosis was performedin 165 patients without drainage. In addition， side-to-side anastomosis was performed in 2 patients without drainage.Results There were 34 cases （6.46%） of pancreatic leakage， 8 cases （1.52%） of anastomotic bleeding in pancreaticoje-junostomy， and 32 cases of death （6.08%）. ① The pancreatic leakage rate of mucosa-to-mucosa anastomosis was signi-ficantly lower than that of end-to-side invaginated anastomosis 〔4.18% （15/359） versus 11.52% （19/165）， χ2=10.029， P=0.002〕. There was no significant difference of the anastomotic bleeding incidence between mucosa-to-mucosa anasto-mosis and end-to-side invaginated anastomosis 〔1.67% （6/359） versus 1.21% （2/165）， χ2=0.159， P=0.691〕. ② In the mucosa-to-mucosa anastomosis group， the pancreatic leakage rates in the ones with internal drainage and external drainage were lower than those in the ones without drainage， respectively （2.68% （4/149） versus 11.25% （9/80）， χ2=7.132， P=0.008；1.54% （2/130） versus 11.25% （9/80）， χ2=9.410， P=0.002）；which was no significant difference between the ones with internal drainage and external drainage 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕. But there were no significant differences for both the pancreatic leakage 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕and anastomotic bleeding incidence 〔2.68% （4/149） versus 1.54% （2/130）， χ2=0.433， P=0.510〕 between the ones with internal drainage and external drainage. Conclusions Mucosa-to-mucosa anastomosis has a lower pancreatic leakage incidence as compared with end-to-side invaginated anastomosis. However， there is no significant difference of the anast-omotic bleeding incidence. Internal or external drainage could reduce the incidence of pancreatic leakage， but have no obvious effect to the anastomotic bleeding incidence.
