The present study was performed to identify tumor cells in lymph nodes from colorectal adenocarcinomas considered free of disease by the classic hematoxylin-eosin stain, based on the detection of the carcinoembryonic antigen (CEA) and cytokeratins in neoplastic epithelial cells. For this purpose, 603 lymph nodes from 46 lesions were stained by the(More)
BACKGROUND Mirizzi syndrome is a rare complication of prolonged cholelithiasis, characterized by narrowing of the common hepatic duct due to mechanical compression and/or inflammation due to biliary calculus impacted in the infundibula of the gallbladder or in the cystic duct. OBJECTIVES To describe a series of eight consecutive patients with Mirizzi(More)
AIM To prospectively explore the role of carcinoembryonic antigen (CEA) in gallbladder bile in patients with colorectal carcinoma and the morphological and clinical features of neoplasia and the occurrence of hepatic metastases. METHODS CEA levels in the gallbladder and peripheral blood were studied in 44 patients with colorectal carcinoma and 10 patients(More)
BACKGROUND The problem of the relationship between blood carcinoembryonic antigen (CEA) levels and tissue CEA content in colorectal carcinoma, and the mechanisms for CEA release from tumor cells in tissue adjacent to the neoplasm is important to understanding the biology of colorectal carcinoma. It has not been adequately explained whether CEA in the(More)
BACKGROUND There is controversy regarding the optimal therapy for primary non-Hodgkin gastric lymphoma with some authors defending surgical extirpation either alone or in association with radiotherapy and or chemotherapy, especially in relation to the earlier stages of the disease. AIM To analyze the clinical-pathological features and the results of(More)
Objective: The aim of the present study was to evaluate the effects of total splenectomy and proximal gastric vagotomy (PGV) isolated or associated to the vascularization of the stomach. Methods: Twenty-eight dogs were distributed in: group A – animals undergoing laparotomy and gastric manipulation; group B – animals undergoing PGV; group C – animals(More)
