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 2 Bile reflux grades. During the endoscopic examination, a modified biliary reflux classification in three grades was applied. A: grade 0, absence of bile (Figure 2A); B: grade 1, small amount of bile located in the bottom of residual stomach without overflow (Figure 2B); C: grade 2, bile spilled into the jejunum with tidal rhythm (Figure 2C).
