Before the pancreatic anastomosis is performed, two vertical mattress sutures are applied on both sides of the main pancreatic duct, to consolidate the pancreas. Suture-threads with straight needles are used. The sutures are placed 2-3 mm away from the pancreatic cut end and penetrate the complete pancreatic parenchyma. Care is taken to avoid injury to the main pancreatic duct. The vertical mattress sutures are tied firmly.
