Restoration of Dehiscent Pancreaticojejunostomy Causing a Major Postoperative Pancreatic Fistula by Reinsertion of a Pancreatic Duct Tube Using the Rendezvous Technique

Introduction: A postoperative clinically relevant pancreatic fistula can cause severe sequelae. We aimed to describe our minimally invasive procedure (rendezvous technique) for the treatment of a pancreatic fistula resulting from pancreaticojejunal anastomosis dehiscence involving a dislodged main pancreatic duct tube. Methods: In our rendezvous technique, a guidewire is advanced into the jejunal lumen from the access site of the drainage tube and is caught by a snare catheter, which is used to replace the dislodged main pancreatic duct tube. Then, the guidewire is passed from the access site of the drainage tube to the site of the dislodged main pancreatic duct tube. A sheath is inserted along the route of the dislodged main pancreatic duct tube and is placed across the pancreaticojejunal anastomosis over the guidewire. Another guidewire is advanced into the main pancreatic duct via the sheath, and a new main pancreatic duct tube is inserted into the main pancreatic duct over the second wire. This technique was performed in two patients with a pancreatic fistula. Results: Our rendezvous technique was successfully performed in a 73-year-old man with an intractable clinically relevant pancreatic fistula and large discharge from the drain and a 74-year-old woman with a pancreatic fistula and fluid collection between the elevated jejunum and remnant pancreas. Discharge from the drain and fluid collection decreased after the procedure. Conclusion: Our rendezvous technique is an effective minimally invasive approach for a pancreatic fistula resulting from pancreaticojejunal anastomosis dehiscence.
