Methods Fifty-four cases of periampullary carcinomas, which were examined by MRCP and confirmed by operation and pathology, were divided into two groups: 28 cases with carcinomas of the head of pancreas and 26 cases with ampullaregion carcinomas (including: 10 cases with distal common bile duct carcinoma, 10 cases with ampullary carcinoma, 6 cases with duodenal papillary carcinoma).
Methods Analyses were made on the clinical data of 22 patients with DPT proved by operation and pathology from 1977 to 1999. Results There were 17 patients with duodenal papillary carcinoma, 5 with duodenal papilloma in this series.
Three patients received pancreaticoduodenectomy and pancreaticojejunostomy for associated duodenal papillary carcinoma and were alive on postoperative follow-up of 10 months, 12 months and 18 months respectively.
The corresponding rate of diagnosis in assessing the depth of malignant invasion of carcinoma of Vater papilla to duodenal wall and discovering enlarged surrounding lymph nodes was 70% and 75% respectively comparing with the pathological findings.
Methods The CT signs of 18 cases of pancreatic cancer which include 13 cases of pancreas caput cancer,3 cases of pancreas corpus cancer and 2 cases of panceras cauda cancer were studied and compared with 7 cases of duct ampulla cancer,5 cases of duodenal papilla cancer,4 cases of inferior choledochus duct cancer and 3 cases of inflammatic mass in pancreatic caput.
This paper presents 30 patients with extrahepatic obstructive jaundice in our hospital were examined with RUTA in a year or so,and then they were all operated upon. Among them were 12 cases of common bile duct gallstone, 9cancer of the head of the pancreas,4 papilla cancer of the duodenum, 2 cholangiocarcinoma and another 2 cancer of hepatic duct,and 1 case of stricture of the upper part of common bile duct.
Methods There are 58 patients in combined therapy group; ERCP were done on all patients. Six patients with duodenal papilla cancer were first treated with endoscopic local excision of papilla;
Results The K-ras gene point mutation rate in peripheral blood of pancreatic adenocarcinoma was 38.1%(8/21). No mutant K-ras gene was noted in specimens of acute pancreatitis,chronic pancreatitis,insulinoma,ampullary carcinoma,duodenal papillary adenocarcinoma,stomach cancer,liver cancer and cholelithiasis.
Result The K-ras gene point mutation rate in duodenal secretion and in ascites were 17.4% (4/23) and 31.6% (6/19) respectively in patients with pancreatic carcinoma; while it was not noted in specimens collected from those with acute pancreatitis, chronic pancreatitis, insulinoma, ampullary carcinoma, biliary duct carcinoma,duodenal papillary adenocarcinoma , stomach cancer and liver cancer .
Result:K ras gene point mutation rate in above specimens were 74.2%, 95.1% ,91.4% and 94.1% respectively. No mutant K ras gene was found in tissues and pancreatic juice of all examined chronic pancreatitis,insulinoma,ampullary carcinoma,bile duct carcinoma, duodenum papillary adenocarcinoma and injured pancreas,no false positive case occurred. Conclusion:The approach is rapid,convenient,specific as well as sensitive.
Results The K-ras gene point mutation rate in duodenal juice of pancreatic adenocarcinoma was 17. 4%(4/23). No mutant K-ras gene was noted in specimens of acute pancreatitis,chronic pancreatitis, insulinoma, ampullary carcinoma, bile duct carcinoma, duodenal papillary adenocarcinoma and stomach cancer.
Results Only 24 patients were correctly diagnosed before operation. 27 patients were missdiagnosed as thyroid adenoma,thyoid cystadenoma,Hashmoto,s thyroiditis,subacute thyroiditis,and thyroid papillary adenocarcinoma.
In the majority of reported cases, no thyroid dysfunction or lesion has been noted, although rare instances of papillary carcinoma have been described.
The patient was a 74-yr-old man with amyloid light-chain (AL) amyloidosis-associated PCD who had a null-cell adenoma of the pituitary and a latent papillary carcinoma of the thyroid gland, as well as a tubular adenoma of the sigmoid colon.
There are many reported predisposing factors for thyroid papillary carcinoma, including genetic factors [1], previous irradiation [2,3], abnormal iodine intake [4-6] hyperthyroidism [7], pregnancy [8], and a dyshormonogenetic state [9].
When the affected organ was considered, a statistically significant difference in survival was observed: At 88 wk, survival was 0% for pancreatic and common bile duct cancer patients, and 18.2% at 175 wk for Vater's papilla cancer patients (p=0.04).
This paper presents 30 patients with extrahepatic obstructive jaundice in our hospital were examined with RUTA in a year or so,and then they were all operated upon. Among them were 12 cases of common bile duct gallstone, 9cancer of the head of the pancreas,4 papilla cancer of the duodenum, 2 cholangiocarcinoma and another 2 cancer of hepatic duct,and 1 case of stricture of the upper part of common bile duct. In 29 of the 30 patients, expanded biliary ducts were shown on the screen of RUTA, and the position ...
In this paper,the real-time B-mode sonogram of 47 cases of pancreatic and peripancreatic masses proved by surgical,pathological or other examinations were analysed,and the causes of misdiagnosis were discussed.The diagnostic accuracy was 15/18 in pancreatic head carcinoma,8/12 in the body or tail,and 11/17 in the ampulla and papilla,,In the 10 misdiagnosed eases,4 were misjudged in the nature and 4 were mislocated and the rest 2 were misdiagnosed as cholelith.All the 3 nondiagnosed cases were carcinoma of a...
