VALUE OF ENDOSCOPY IN THE DIAGNOSIS OF PO STOPERATIVE ALKALINE REFLUXGASTRITIS

Objective: A long term retrospective study comparing endoscopic lesion s and their relationship with symptoms and histological lesions of pos toperative Alkaline Reflux Gastritis (ARG) between partial gastrectomy Billroth II (n = 25) and the Roux-en-Y (n = 36) is presented. Patient s and methods: In patients operated on with both techniques the clinic al, endoscopic and histological aspects are studied. Results: The pati ents operated on with the Billroth II technique present a higher frecu ency of bile in the gastric remnant and mucosal lesions in the endosco pic study (p < 0.001) compared with the Roux-en-Y group. Bile and muco sal lesions on the gastric stump are more common with symptoms and his tological lesions of postoperative ARG. Conclusions: The endoscopic ev aluation is a valid and reliable examination in the diagnosis and foll ow up of postoperative ARG.
