Background: Different techniques of reconstruction following pancreaticoduodenectomy have been described. A new modification using an isolated Roux‐en‐Y loop is reported. Methods: The isolated loop is taken up to bile duct rather than pancreas as previously described. Results: Seventeen patients have undergone this procedure. Two pancreatic fistulae developed, both following postoperative abscess formation. There was no operative mortality. Conclusion: This reconstruction provides separation of biliary and pancreatic fluid but adds two further benefits: the wide jejunal lumen allows for an easier pancreaticojejunal anastomosis, particularly when operating on a soft pancreas, and separation of gastric and biliary anastomoses prevents the efflux of bile into stomach.
