Application of air insufflation to prevent clinical pancreatic fistula after pancreaticoduodenectomy

Figure 2 Air insufflation test to investigate the pancreaticojejunal anastomosis. An intestinal clamp (A) was used to close the distal intestinal loop approximately 6 cm from the pancreaticojejunal anastomosis (B). Then, the anastomosis was submerged in irrigation fluid, and air was injected gently with a 1 or 5 mL syringe (C) through the pancreatic duct stent to determine whether there were bubbles generated.
