Core Tip
Core tip: Necessity of peri-gastrectomy acid suppression for gastric cancer patients remains controversial. This innovative prospective study showed: before surgery, gastric pH was higher than the threshold of hypoacidity, and affected by age, tumor size and differentiation grade, and potassium and bicarbonate ions; advanced malignancies were accompanied with higher pH; after operation, gastric pH in all groups was of weak-acidity and higher than that pre-gastrectomy; six months later, gastric pH was comparable to that on days 3-5; reflux symptom was significantly associated with patient’s body mass index, direct and indirect bilirubin, and total bile acid, while pH played no role.
