Abstract
In recent years, there has been an increase in numbers of individuals seeking laparoscopic surgical procedures for obesity. The current study compared the benefits and risks between laparoscopic and open Roux-en-Y gastric bypass (RYGBP) performed at the same center for more than 2,000 patients. The study population consisted of 1,077 laparoscopic and 1,198 open RYGBP procedures performed between the years 1999 and 2002. Measurements included population characteristics, anthropometries, complications, and hospital stay. The laparoscopic RYGBP has both advantages and disadvantages. The disadvantages include a longer operative time and a higher incidence of fistulas, internal hernias, and small bowel obstruction. The advantages of the laparoscopic procedure are shorter hospital stay, lower incidence of wound infection, and fewer incisional hernias. Both procedures cause similar changes in body weight, but laparoscopic RYGBP is associated with less lean tissue loss during the early postoperative period. Both laparoscopic and open RYGBP are effective in inducing massive weight loss. There are, however, differences in the benefits and risks between the two procedures.
