[The value of barium double-contrast study in the aftercare of gastrectomy patients (Roux-Y)].

We evaluated 32 patients who had undergone jejuno-oesophagostomy for gastric carcinoma. Double contrast radiography was performed 3 to 36 months after gastrectomy, 3 to 14 days prior to routine endoscopy. Endoscopy is superior to double contrast radiography in detecting tumour recurrence, particularly in small tumours, due to the possibility of biopsy. Double contrast radiography is excellent in demonstrating the afferent loop. We found a high number of jejuno-oesophageal reflux and very different small intestine transit times without correlation to clinical signs and symptoms.
