title: Investigation of the excluded stomach after Roux-en-Y gastric bypass.
abstract: BACKGROUND
  One problem with Roux-en-Y gastric bypass (RYGBP) is that it leaves the bypassed segment not readily available for endoscopic or radiographic examinations.
  
  
  METHODS
  Three males, 50, 54 and 64 years old, suffered from repeated, gastrointestinal bleeding of unknown origin requiring transfusion 1/2, 1 and 7 years after RYGBP. Access to the stomach was obtained by an ultrasound-guided percutaneous gastrostomy.
  
  
  RESULTS
  We could perform endoscopy, barium studies and gastric acid output measurements through the gastrostomy. Histological gastritis, low acid output and absence of H. pylori infection were found.
  
  
  CONCLUSIONS
  We were able to exclude severe gastric disease in our patients.
