OBJECTIVE: To identify through ecoendoscopy (EE) hyperecogenic pancreas and to determinate risk factors for it in a sample of patients evaluated between June 2005 and May 2010. MATERIAL AND METHODS: Cases and controls study, retrospective observational study, in a population of 5,495 patients; from them 989 were selected as cases (with an increase of partial or global ecogenicity of the pancreas) and 642 controls (with a normal pancreatic ecopattern). Demographical, clinical and ecoendoscopical variables from both groups were compared; OR were calculated with their 95%CI, after bivariate and multivariate risk factors analyses...

UNLABELLED: Insulinoma is the most frequent neuroendocrine pancreatic tumor and is the main cause for hypoglicemia due to endogenous hyperinsulinism. We performed an analysis of a clinical series in order to study the clinical and biological spectrum of presentation, the preoperatory imagistic diagnosis and results of the surgical approach. Between 1986-2009, 30 patients with symptoms suggesting an insulinoma were hospitalized in our department. Preoperatory localization of insulinomas was possible in 16 patients...

Insulinomas are rare endocrine pancreatic tumors whose incidence has been increasing in recent years owing to early detection by clinical and radiologic, such as remote neural monitoring, computed tomography (CT), and ultrasound (US) findings. The classical treatment consists of open surgical resection, which is associated with relative morbidity and mortality rates. The aim of this paper was to present 5 patients who were diagnosed with pancreatic insulinomas that were treated by laparoscopic resection. Five (5) patients, ranging from 14 to 45 years and presenting with classical Whipple Triad, had lesions ranging from 1...

BACKGROUND: [corrected] The elastic band ligation is the method of choice for treatment of esophageal varices. The action mechanism is a mechanical varices compression with thromboses. Based on this concept we developed a ligature method using pretied loop made with polyamide thread for the treatment of esophageal varices. OBJECTIVE: The present study describes and evaluates the feasibility of the treatment of esophageal varices by the ligature method using pretied loop made with polyamide thread and analyzes the local changes of the ligations and the results, concerning safety, efficiency and complications of this procedure...

OBJECTIVE: To asses the diagnostic accuracy of endoscopic ultrasonography (EUS) for the local and regional staging of esophageal cancer, and its possible alteration resulting from the performance of preoperative chemoradiation. METHODS: Prospective study of 85 consecutive patients with esophageal cancer evaluated by EUS and operated between January 1992 and December 1995. 28 of these patients had received previous induction therapy. In all cases, EUS examination was performed by the same physician not informed about the results of previous morphological explorations...

Pancreatic tumors are the fourth cause of death in Occident: the 5-year-survival rate is less than 5% because of diagnostic difficulties, low clinical expression at early stage, and complexity of the surgical treatment. The role of ultrasound (US) is in early diagnosis, because also in early cancer there could be lymphatic spread or peritoneal involvement. There are multiple modalities to study the pancreas with US: abdominal US, "contact" US (endosonography and intra-operative or laparoscopic US). The first is not invasive, cheap but limited by extrinsic and intrinsic factors, the latter are respectively characterized by high cost, and need of endoscopic specialists for endosonography, the complementarity to laparoscopy or surgery for the laparoscopic/intraoperative US...
