We produced experimental models of pancreatic end‐to‐end anastomosis, including ductal end‐to‐end anastomosis (with or without stent) and pancreaticojejunostomy, using mongrel dogs, with a view to evaluating reconstructive procedures after segmental pancreatectomy. We examined macroscopic findings, pancreatograms, and microangiographic and histopathological findings to determine whether pancreatic end‐to‐end anastomosis was as practicable as pancreaticojejunostomy. Macroscopic findings showed no suture failure in any animal in the end‐to‐end anastomosis group. Pancreatography revealed obstruction of the stent tube in the stent subgroup, but good patency in the no‐stent subgroup. On the imaging of the microvasculature in the end‐to‐end anastomosis group, proliferation of neovascular vessels and formation of communicating vessels were detected. Histopathologically, no suture failure was detected, and the viability of the pancreatic end‐to‐end anastomosis was confirmed. From this experiment, we concluded it that it was possible to employ pancreatic end‐to‐end anastomosis after segmental pancreatectomy in the clinical situation.
