From December 1981 to October 1997, we had performed 1559 cases of intrahepatobiliary tract stones by surgery alone/or with cholangioscopy, of which 332 cases were left intrahepatobiliary tract stones (accounted for 33.9%), 111 right intrahepatobiliary tract stones (accounted for 11.3%) and 545 cases in both sides (54.7%). 324 patients complicated with stricture of biliary tract (32.3%), of which 156 cases (48.2%) were stricture of left intrahepatobiliary tract, 107 cases (33.0%) stricture of right intrahepatobiliary tract, 61 cases (18.8%) stricture of hepatic hilus biliary tract. The operative procedure were: ①hapatic lobe or segment resection, ②high cholangiotomy and palstic repair, ③choledochojejunostomy and ④T-tube or U-tube drainage with removal of stones by cholangioscopy later. The operative procedure should be based on different types of intrahepatobiliary tract stones and patholigical features. The result indicates that cholangioscopy may play an important role in the treatment of intrahepatobiliary tract stones.
Objective To investigate the relationship between pancreatic cancer and pancreatic duct stone and the clinical features, diagnosis, treatment of pancreatic duct stone with pancreatic cancer. MethodsThe clinical data of 10 patients suffering pancreatic duct stone with pancreatic cancer, admitted to our hospital from March 1992 to September 2007， were retrospectively analyzed. ResultsThe major symptom was abdominal pain (8/10) in pancreatolithiasis with pancreatic cancer and there were few characteristic symptoms. The positive percentages ofdiagnosis of this disease with B ultrasonography, CT and ERCP wererespectively 4/10, 6/10 and 5/5. The percentage of preoperative final diagnosis was 7/10, meanwhile there were 2 patients who were diagnosed during the operation and 1 patient with missed diagnosis. Surgical treatment was received by all of the patients. Pancreatoduodenectomy was performed in 8 patients. Pancreolithotomy plus pancreaticojejunostomy were performed in 1 patient because of misdiagnosis, while biopsy was only done in the last one. ConclusionCombination of multiple examinations can improve the accuracy of diagnosis of this disease. However, the preoperative diagnosis is not completely believable, and it is necessary to perform the pathological examination during operation. Pancreatoduodenectomy should be used as the first choice for pancreatic duct stone with pancreatic cancer.
