title: [Morphology and physiopathology of Billroth I gastroduodenostomy].
abstract: 97 patients subjected from 1 to 7 years previously to partial gastric resection by gastroduodenostomy (Billroth I) have been studied endoscopically and radiologically. Acid secretion after pentagastrin injection has also been determined. The most frequent mucous alterations identified by endoscopy were erosions in the stomach residue with inflammatory granulation in the anastomosis region. Recurrent ulcers were observed in 3% of cases. Acid secretion was reduced in 87% by comparison with the preoperative picture. The quantity of residual recretion depended on the greater curvature of the residual stomach. Radiological studies highlighted functional modifications indicative of organized motility in the residual stomach and pseudopyloric function at anastomosis level making coordinated draining possible.
