Application of "papillary-like main pancreatic duct invaginated" pancreaticojejunostomy for normal soft pancreas cases.

ABSTRACT: Pancreaticojejunostomy is the key procedure of pancreaticoduodenectomy. Our study introduced a new pancreaticojejunal (PJ) anastomosis named "papillary-like main pancreatic duct invaginated" pancreaticojejunostomy. Nighty-two patients underwent pancreaticojejunostomy with either conventional duct-to-mucosa pancreaticojejunostomy or the new "papillary-like main pancreatic duct invaginated" techniques were analyzed retrospectively from January 2010 to September 2012. The incidence of pancreatic fistula was 15.7% (8/51) for the "papillary-like main pancreatic duct invaginated" group and 19.5% (8/41) for the duct-to-mucosa fashion respectively. It is noteworthy that the rate of grade B/C postoperative pancreatic fistula (POPF) in the "papillary-like main pancreatic duct invaginated" group was significantly lower than that of the duct-to-mucosa group (P = 0.039). There were no differences in the incidence of postoperative morbidity and mortality such as postoperative hemorrhage, delayed gastric emptying or remnant pancreatitis. The "papillary-like main pancreatic duct invaginated" pancreaticojejunostomy could provide a feasible option to pancreatic surgeons for patients with normal soft pancreas.

Project description:BACKGROUND:Partial pancreatoduodenectomy is performed for malignant and benign diseases of the pancreatic head region. The procedure is considered highly difficult and highly invasive. Postoperative pancreatic fistula (POPF) is an important complication because of several consequent complications, including intraabdominal haemorrhage, often increasing hospital stays and surgical mortality. Although many kinds of pancreaticojejunostomy aimed at reducing POPF have been examined to date, the technique has not yet been standardized. We devised a new method using double-coated polyglycolic acid felt after pancreaticojejunostomy. The aim of the PLANET-PJ trial is to evaluate the superiority of polyglycolic acid felt reinforcement in preventing POPF after pancreaticojejunostomy in patients undergoing partial pancreatoduodenectomy to previous anastomosis methods. METHODS:Patients diagnosed with pancreatic or periampullary lesions in whom it is judged that the main pancreatic duct diameter was 3?mm or less on the left side of the portal vein without pancreatic parenchymal atrophy due to obstructive pancreatitis are considered eligible for inclusion. This study is designed as a multicentre randomized phase III trial in Japan and the Republic of Korea. Eligible patients will be centrally randomized to either group A (polyglycolic acid felt reinforcement) or group B (control). In total, 514 patients will be randomized in 31 high-volume centres in Japan and Republic of Korea. The primary endpoint is the incidence of POPF (International Study Group of Pancreatic Surgery grade B/C). DISCUSSION:The PLANET-PJ trial evaluates the efficacy of a new method using double-coated polyglycolic acid felt reinforcement for preventing POPF after pancreaticojejunostomy. This new method may reduce POPF. TRIAL REGISTRATION:ClinicalTrials.gov, NCT03331718 . University Hospital Medical Information Network Clinical Trials Registry, UMIN000029647.
