Surgical and micro-invasive treatment of pancreatic duct stones: an analysis of 42 patients

Pancreatic duct stone is a sequel of chronic pancreatitis and may be found in the main ducts, side branches or parenchyma. These stones obstruct the pancreatic ducts and produce ductal hypertension, which leads to pain, the cardinal feature of CP. Surgical operation has been the preferred treatment of pancreatic duct stones in many domestic and external pancreatic medical centers. Lithotomy by longitudinal pancreatic duct incision and Roux-en-Y anastomosis of pancreatic duct to jejunum is the main and effective surgical procedure, while micro-surgery was also rational for the treatment of pancreatic duct stones. However, further studies with a larger sample size and longer follow-up duration are needed to improve the surgical technique and verify our initial results.
