全胃幽門輪温存膵頭十二指腸切除術（PpPD）4年後に繰り返す膵炎に対して膵管チューブ抜去が奏功した1例

A 54-year-old man had repeated pancreatitis since three years after pylorus-preserving pancreatoduodenectomy (PpPD) and reconstruction by the modified Child method. Since abdominal pain appeared after meals, a pancreatic duct tube was removed endoscopically, which resulted in an improvement. It has been postulated that a pancreatic duct tube, used at the anastomosis between the pancreas and gastrointestinal tract, is spontaneously dislodged or creates a spatial gap with the wall of the main pancreatic duct enough to let the pancreatic juice outflow. However, endoscopic removal of the tube remained in place was significantly effective. We here discussed this case with reference of previous published reports.
