Helicobacteriosis of the operated stomach in peptic ulcer

: After Billorth-II resection of the stomach for ulcer the contamination of the stump with Helicobacter pylori (HP) was detected in 73.7% of the cases, for ulcer of the duodenum--in 81.8% of the patients. At later terms after selective proximal vagotomy (SPV) all the patients were HP-positive, after SPV with draining operations 92.3% of the patients were HP-positive. The degree of inflammatory alterations in the mucosa was proportional to the degree of its bacterial dissemination. The HP contamination of the gastric mucosa after operation had no marked influence on the clinical course of the remote postoperative period. Spontaneous elimination of HP was observed in 42.9% of the patients with the developing achlorhydria of the operated stomach.
