- W2372851560 abstract "Objective To evaluate the clinicopathologic features and value of endoscopy in the diagnosis of ampullary carcinoma.Methods The clinicopathologic data of 28 patients with ampullary carcinoma were retrospectively reviewed and analyzed.Accuracy rates of ultrasonography,computerized tomography and endoscopy in the diagnosis of ampullary tumors were assessed compared with postoperative pathologic finding.TNM staging was performed.Results The leading symptoms of ampullary carcinomas were jaundice(82.1%),upper abdominal pain(35.7%).Courvoisier′s sign existed in 42.8 % of patients.24 patients had common bile duct dilation,and pancreatic duct dilation in 7 patients.Three macroscopic appearances of the tumor were identified,including polypoid protruding(16 cases),ulcerative masses(8 cases),or infiltrating masses(4 cases).Histologic examination revealed well differentiated adenocarcinoma in 14 patients,moderately differentiated adenocarcinoma in 13 patients.T 3,T 4 lesion had metastatic lymph nodes.About 35.7 percent of ampullary carcinoma could be detected by ultrasonography,57.1 percent by CT,and 91.7 percent by endoscopy(P0.01).ERCP showed the distant stenosis of the bile duct,irregular infilling defect,and biliary or pancreatic duct dilation.Conclusion The leading clinical characteristics of ampullary carcinoma are painless jaundice companied by common bile duct dilation.Endoscopy has been shown to be superior to ultrasonography and CT for diagnosis of ampullary carcinoma." @default.
