Objectives: Causes may be found in most cases of acute pancreatitis, however no etiology is found by clinical, biological and imaging investigations in 30% of these cases. Our objective was to evaluate results from endoscopic ultrasonography (EUS) for diagnosis of gallbladder microlithiasis in patients with unexplained (idiopathic) acute pancreatitis.
Methods: Thirty-six consecutive non-alcoholic patients with diagnoses of acute pancreatitis were studied over a five-year period.
Context: EUS-FNA is increasingly being used in operable pancreatic carcinoma cases identified by CT.
Objectives: Determine the safety, accuracy and clinical utility of EUS-FNA for T, N and TN staging and vascular injury assessment in proven ductal pancreatic carcinoma.
Patients: Fifty-two consecutive patients (29 women and 23 men) with histologically ductal pancreatic carcinoma, with an excellent possibility of mass resection assessed by helical computerized tomography, were studied.
Background: Gastric adenocarcinoma is the major cause of death by cancer in Brazil. For the planning of the treatment and evaluation of the prognosis, the preoperative staging according to the TNM classification is very important.
Aim: To evaluate the results of endoscopic ultrasound for the T and N categories.
Purpose: verify the cytological and histological aspects of the regeneration of fragments of autologous and heterotopic spleen implanted in peritoneal cavity and subcutaneous screen in Wistar albino rats.
Methods: forty four Wistar rats were assigned to one of two groups A (n=22) and B (n=22), which received their implants in subcutaneous screen and peritoneal cavity, respectively, under anesthesia. Those groups were redistributed in two other subgroups A1 (n=11) and B1 (n=11), which received one and four splenic fragments in the areas of study.
