Investigation of the excluded stomach after Roux-en-Y gastric bypass

Background: One problem with Roux-en-Y gastric bypass (RYGBP) is that it le aves the bypassed segment not readily available for endoscopic or radiograp hic examinations. Materials and 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 u ltrasound-guided percutaneous gastrostomy. Results: We could perform endoscopy, barium studies and gastric acid output measurements through the gastrostomy. Histological gastritis, low acid out put and absence of H. pylori infection were found. Conclusion: We were able to exclude severe gastric disease in our patients.
