BACKGROUND AND AIMS Helicobacter pylori (H. pylori) infection has been suggested as a cause of impaired drug absorption. This infection leads to alteration of the gastric acid secretion that may change the conformational characteristics of drugs and their intestinal absorption leading to uncertainties about the dose to administer and the therapeutic results. A systematic review was undertaken t...

BACKGROUND The major long-term complication of laparoscopic adjustable gastric banding (LAGB) is dilatation of the gastric pouch, that is reported with a frequency ranging from 1 to 25%, and often requires removal of the band. In addition to the usual recommendations of bariatric surgery centers and dietetic advice to prevent this complication, over the last 4 years we introduced a technical mo...

BACKGROUND The reported incidence of ulcer formation in the gastric tube in esophageal replacement is rare. CASE PRESENTATION This is the first report of a case of cerebral air embolism as a result of spontaneous perforation of an ulcer in the constructed gastric tube into the pulmonary vein during post-operative follow-up in a patient with esophageal cancer. CONCLUSIONS Cerebral air emboli...

BACKGROUND Acquired esophageal strictures in children are often the result of ingestion of caustic agents. We describe 2 children with severe esophageal strictures following lye ingestion, who successfully underwent esophagectomy and gastric pull-up utilizing combined thoracoscopic and laparoscopic techniques. METHODS This was a retrospective chart analysis of both patients. CASE 1: A 17-year...

Studies of gastric acid secretion and mucosal appearances have been made in a group of 14 patients suffering from hypopituitarism. Achlorhydria was found in six of the patients suffering from Addison's disease but in only one patient suffering from hypopituitarism. In both groups the mean gastric secretion of hydrochloric acid was considerably lower than in a group of control subjects and repla...

Abstract The therapeutic usage of EUS is being developed. EUS-guided biliary drainage (EUSBD) a recognized viable replacement for percutaneous transhepatic (PTBD) in severe cases with the obstructive disease having ERCP failure due to cannulation or those surgically altered anatomies, such as hepatico-jejunal anastomosis following Billroth II reconstruction, Roux-en-Y limb, Whipple procedure, g...

Study of groups of asymptomatic subjects with an increased likelihood of developing gastric cancer is a fundamental approach to the problem of gastric cancer. The selection of such groups, however, has remained a difficult task.' Pernicious anemia and its pathologic substrate, gastric atrophy, frequently associated with gastric cancer, may be an important precursor of gastric malignancy."8 Mors...

Esophagectomy and esophageal replacement with a gastric tube are the procedures of choice for resectable esophageal carcinoma. Postoperative stricture at the level of the esophagogastric anastomosis is a wellknown complication of this procedure. Much less common is the development of a benign fistula communicating the gastric tube and the airway. We report the clinical case of a patient in whom...
