Closure of the distal pancreatic stump with a seromuscular flap.

We describe herein our new method for transecting the pancreas and closing its stump in distal pancreatectomy, devised to decrease the risk of pancreatic fistula formation. With this technique, the pancreas is transected in such a way that a convex stump is left, whereby the pancreatic secretions from the parenchyma near the pancreatic stump are fully drained into the main pancreatic duct. A pedicled seromuscular flap of the stomach or jejunum is then used to cover the cut surface of the pancreas. This new technique provides tight closure of the pancreatic stump after distal pancreatectomy.
