AbstractNonfibrotic pancreases with a nondilated duct are susceptible to pancreatic fistula or leakage following pancreaticoduodenectomy. We developed a novel pancreatic duct-invagination anastomosis using an ultrasonic dissector and applied this technique to 14 consecutive pancreaticoduodenectomies and 1 segmental pancreatectomy for otherwise normal pancreases. With the aid of an ultrasonic dissector, even branch pancreatic ducts were skeletonized, ligated securely, and divided during pancreatic transection. Moreover, the main duct was exposed (> 1 cm) easily by ultrasonic dissection and a small-caliber pancreatic tube was inserted into the duct on the stump. Subsequently, pancreatic duct invagination could be easily done through a 10 G intravenous catheter passed through the gastrointestinal tract. The main duct was anchored to the adjacent serosa, but any pancreatic parenchymal sutures, possibly leading to internal laceration and/or parenchymal ischemia particularly in soft nonfibrotic pancreases, were avoidable during the procedures. All the anastomoses were done within 10 minutes. Only 1 patient (6.7%)developed pancreatic fistula, which resolved spontaneously in 21 days postoperatively. Neither anastomotic leakage nor remnant pancreatitis was seen in this series. Although a prospective, randomized study is needed, this technique may contribute to reduced morbidity after pancreaticoduodenectomy for a nonfibrotic pancreas with a nondilated main duct.
