Purpose: Billroth I and II reconstructions are commonly performed after a distal subtotal gastrectomy. However, both may cause duodenogastric and duodenogastroesophageal reflux, which are conditions reported to have carcinogenic potential. This study investigated which reconstructive procedure would be most effective in prevent bile reflux into the gastric remnant after a distal gastrectomy.
Methods: A group of 43 patients who underwent a curative distal gastrectomy for gastric cancer were assigned to three groups prospectively according to the reconstructive procedure undertaken: 14, Billroth I (B-I); 14, Billroth II with Braun anastomosis (B-II with Braun); and 15 Billroth II (B-II). The bile reflux period (percent time) for the gastric remnant was measured using a Bilitec 2000 under standardized conditions. The endoscopic findings for reflux gastritis were classified into four grades.
Results: The mean±standard error time of bile reflux in B-I, B-II with Braun and the B-II groups was 30.9±3.9%, 32.8±5.1% , and 60.9±7.0%, respectively. The B-II group showed significantly higher levels of the % time of bile reflux than the B-I or B-II with Braun groups (P＜0.001). Regarding the endoscopic classification for reflux gastritis, the remnant stomach after B-II showed significantly more severe and extensive gastritis than that after the B-I and B-II with Braun procedures (P=0.003). There was also a positive correlation between the degree of % time of bile reflux and the extent of gastritis in the gastric remnant (P＜0.001).
Conclusion: After a distal subtotal gastrectomy, a B-II reconstruction is associated with a high reflux of duodenal content, whereas a Braun enteroenterostomy after a B-II reconstruction minimized the reflux at the levels of a B-I reconstruction. (J Korean Surg Soc 2006;71:256-261)
