Long-term acid suppressive therapy may prevent the relapse of lower esophageal (Schatzki's) rings: a prospective, randomized, placebo-controlled study.

Objectives: Distal esophageal (Schatzki's) rings are a frequent cause of dysphagia. Bougienage is generally effective, but relapses are common. The aim of this study was to evaluate the effect of long-term antisecretory therapy on the relapse rate of lower esophageal rings after successful bougienage with Savary dilators.

Postbiopsy intramural hematoma of the duodenum in an adult with Noonan's syndrome.

Intramural duodenal hematoma is a rare complication of endoscopic biopsy. It is usually seen in children with growth failure and in patients with bleeding disorders or who are anticoagulated. It is frequently associated with acute pancreatitis.

Gastric electrical activity in patients with cholelithiasis undergoing laparoscopic cholecystectomy: a prospective controlled study.

Background: The aim of the present study was to evaluate the effect of gallstone disease (GD) and laparoscopic cholecystectomy on gastric electrical activity of slow waves, which was recorded via transcutaneous electrogastrography (EGG).

Methods: Twenty-one consecutive patients (M/F: 12/9, 52.7 +/- 15 years old) with GD and no previous history of abdominal operations or known disease affecting gastrointestinal motility were studied.
