The investigators hypothesized that sympatholytic effect of dexmedetomidine would attenuate the hemodynamic instability and decrease in the splanchnic blood flow caused by pneumoperitoneum during laparoscopic surgery. This study is to investigate the effect of intraoperative dexmedetomidine infusion on postoperative bowel movement in patients undergoing laparoscopic gastrectomy.
