A comparison of Roux-en-Y and Billroth-I reconstruction after laparoscopy-assisted distal gastrectomy.
OBJECTIVE
The present study evaluated the efficacy of Roux-en-Y (R-Y) reconstruction and Billroth-I (B-I) reconstruction after laparoscopy-assisted distal gastrectomy (LADG).


METHODS
Between October 2000 and February 2006, a total of 133 consecutive patients who underwent LADG for gastric carcinoma were classified into 2 groups according to reconstruction (B-I, n = 65; R-Y, n = 68). Parameters analyzed included patients and tumor characteristics, operative details, postoperative outcomes, and nourishment state. Endoscopic findings of the gastric remnant and lower esophagus were evaluated at 12 months postoperatively.


RESULTS
Regarding postoperative complications, no significant differences were found between groups. In the B-I group, 3 patients developed anastomotic leakage and 4 patients suffered anastomotic stricture requiring endoscopic balloon dilation. So-called functional stasis after R-Y reconstruction was not found in this study. Incidence of heartburn at 12 months postoperatively was 37% in the B-I group and 8% in the R-Y group (P = 0.0002). Amount of meal consumed compared with preoperative value at 12 months postoperatively was significantly higher for the R-Y group than for the B-I group (83.6% +/- 15.3% vs. 77.8% +/- 16.0%; P = 0.047). Endoscopic findings showed that incidence of remnant gastritis was significantly lower in the R-Y group than in the B-I group (12% vs. 34%; P = 0.002). Bile reflux into the remnant stomach was not observed in the R-Y group.


CONCLUSIONS
R-Y reconstruction seems superior to B-I reconstruction for preventing both bile reflux into the gastric remnant and postoperative complications. We consider R-Y reconstruction as a feasible and safe method for LADG.
