Methods Consecutive patients seen bet ween January 1996 and September 2001 with benign gastric outlet obstruction (def ined as stenosis preventing the passage of a 9-mm diameter endoscope, vomiting, succussion splash, and recent weight loss) were prospectively studied. Exclusio n criteria were the following: refusal to undergo dilation, and gastric outlet o bstruction because of malignancy. At endoscopy, antral biopsy specimens were obt ained for histopathologic evaluation and for a rapid urease test for Helicobacte r pylori infection.Patients then underwent dilation with through-the-scope bal loons.After balloon dilation, patients with Helicobacter pylori infection were t reated to eradicate the infection. Results Fifty one patients (33 men, 18 women; median age 65 years; IQR 44-79 years) were studied; 33 consented to endoscopic balloon dilation. Symptom resolution occurred in 25 patients (14 Helicobacter p ylori positive, 11 Helicobacter pylori negative).During amedian follow-up of 24 months (IQR 16-40 months), 3 of 14 patients in the Helicobacter pylori positiv e group and 6 of 11 in the Helicobacter pylori negative group developed further ulcer complications (p=0.039). Conclusions After endoscopic dilation for gastric outlet obstruction, eradication of Helicobacter pylori infection is associated with fewer ulcer complications.展开更多
