Introduction: Nationwide studies are mandatory to assess changes in the epidemiology of HBV infection in Europe., Aim: To describe epidemiological characteristics of HBsAg-positive patients, especially inactive carriers, and to evaluate how practitioners manage HBV patients in real life., Methods: Belgian physicians were asked to report all chronically infected HBV patients during a one-year period., Results: Among 1,456 patients included, 1,035 (71%) were classified into one of four phases of chronic infection: immune tolerance (n = 10), HBeAg-positive hepatitis (n = 248), HBeAg-negative hepatitis (n = 420) and inactive carrier state (n = 357 HBeAg-negative patients with ALT

Varices of the entire colon are very rare. This rare cause of massive lower gastrointestinal hemorrhage is almost invariably associated with cirrhosis of the liver and consequent hypertension or portal venous obstruction. We report about a patient with massive lower gastrointestinal bleeding from extensive colonic varices. Despite extensive investigation and a follow-up of 3 years, the etiology of the colonic varices could not be determined. Only a few cases of apparent idiopathic (familial or non-familial) colonic varices have been described. Recognition of this abnormality is important, however, because colonic varices may be the cause of recurrent, frequently massive lower gastrointestinal hemorrhage. A misleading endoscopic diagnosis can lead to inappropriate biopsies, resulting in major bleeding.

We describe the case of an adult patient with a benign congenital esophagobronchial fistula. The different types of congenital fistula without atresia or in H form are discussed. We formulate some hypotheses explaining the late occurrence of symptoms in a lesion present since the patient's birth.

In order to explore the relationship between duodenal diverticula and biliary stone disease, we reviewed 2231 endoscopic retrograde cholangio-pancreatography procedures. We found at least one juxtapapillary diverticulum per 239 patients (10.8%). The occurrence of duodenal diverticula increases with age. Patients with duodenal diverticula were older, had more gallbladder stones, more common bile duct stones, had undergone cholecystectomy more frequently, and experienced more frequently common bile duct stone recurrence after cholecystectomy. We thus confirm an association between the presence of diverticula of the second part of the duodenum, and biliary stone pathology, including gallbladder stones, common bile duct stones, and recurrent stones after cholecystectomy. We discuss the aetiopathogeny of this affection.
