This paper reported nine cases of pancreatic lithiasis. Pancreatolithotomy and pancreaticojejunostomy was performed in 4 cases; Pancreatoduodenectomy in 1 case; Laparotomy and biopsy in 1 case complicated with pancreatic carcinoma and hepatic metastasis; And nonoperative treatment in 3 cases. Our data showed that pancreatic fluid stasis caused by stenosis of pancreatic duct and/or the distal segment of bile duct maybe one of the important factors of pancreatic stone formation.
