Randomized controlled trial of uncut Roux-en-Y vs Billroth II reconstruction after distal gastrectomy for gastric cancer: Which technique is better for avoiding biliary reflux and gastritis?

Figure 4 Perioperative potential of hydrogen (pH) in the stomach of the patients. Change of potential of hydrogen (pH) in the remnant stomach was recorded at 8:00 am on the day before surgery as well as 1-5 d after surgery. During the postoperative period, all stomach pH values of group U patients were below 7.00. Conversely, all stomach pH values of group B patients were higher than 7.00.
