Experimental study on operative methods of pancreaticojejunostomy with reference to anastomotic patency and postoperative pancreatic exocrine function

Figure 1 A: Pancreatic duct and jejunal mucosa are sutured, and stitch is only inserted to the submucosal layer of the jejunal wall; B: A piece of unabsorbable thread (7/0 silk) is used to bind together circumferentially the jejunal seromuscular sheath and pancreatic remnant.

Figure 2 Percentage weight gain in pigs undergoing three types of pancreatoenteric anastomosis and in control pigs.

Figure 3 Duct at the cut surface of pancreatic stump was markedly dilated at the end of POW 4 after ligation of the main pancreatic duct.

Figure 4 A: Anastomotic site was incompletely obstructed; B: Duct was blocked in the anastomotic region; C: Normal ductal patency without stenosis at the anastomotic site and without ductal dilatation proximal to it.

Figure 5 Longitudinal specimen reveals good connective tissue union between the pancreatic duct and the jejunal lumen.
