Numbers in parentheses refer to the numbers of patients in each category. To be eligible for the study patients had to be cured postresection and have at least a two-year follow-up from their last postoperative BAO. Patients were stratified into three groups based on their highest postoperative acid secretory level. Patients with or without a previous acid-reducing surgery were classified as postoperative normosecretors if the BAO was <5 or 15 mEq/h, respectively; moderate hypersecretors if BAO was 5–14.9 or 15–24.9, respectively; and extreme hypersecretors if BAO was ≥15 or ≥25 mEq/h, respectively.
