Background:
Pancreatoenterostomic leakage after pancreatoduodenectomy may be caused partly by pancreatic juice leakage from transected branch pancreatic ducts on the pancreatic cut surface that do not drain into the main pancreatic duct after pancreatectomy.
Methods:
We devised a new technique of pancreatic transection using an ultrasonic dissector followed by duct-to-mucosa pancreatojejunostomy, in order to prevent pancreatoenterostomic leakage after pancreatoduodenectomy in patients with a soft pancreas and a small main pancreatic duct. During pancreatic transection, branch pancreatic ducts and blood vessels are adequately skeletonized and securely ligated. The pancreatic duct is anastomosed to the full thickness of the jejunum with four to six interrupted sutures.
Results:
Ten patients with a nondilated pancreatic duct (2 to 3 mm) underwent pancreatoduodenectomy by the present method. During pancreatic transection, 24 to 35 ducts including the pancreatic ducts and blood vessels were skeletonized and ligated. Postoperatively, no patients developed pancreatojejunostomic leakage. The present method may prevent pancreatoenterostomic leakage after pancreatoduodenectomy.
