| Laparoscopic versus Open Gastric Bypass: Comparison of Results Laparoscopic gastric bypass (LGBP) is being performed widely as a treatment of choice for morbid obesity. Advantages over open gastric bypass (OGBP) have not been well documented in controlled studies. The aim of this study is to evaluate the early postoperative outcomes after laparoscope-assisted gastric bypass and open gastric bypass using a matched paired analysis. Method 80 consecutive Laparoscopic gastric bypass patients were matched by age, gender, preoperative BMI, and number of co-morbid medical conditions to 80 open gastric bypass patients. Outcomes included length of stay (LOS), complications, percent excess weight lost (%EWL) and change in BMI over 1 year, time to return to normal activities, and quality of life (QOL). Continuous variables were analyzed using Wilcoxon Signed Ranks and discrete data were analyzed with McNemar tests. Results Baseline variables were matched (Laparoscopic gastric bypass/OGBP); age 43/42, mean preoperative BMI 44/46, co-morbid conditions 2.5/2.8. LOS was significantly shorter in the LGBP vs. open gastric bypass group (3.6 vs. 4.3 days). There was a trend to more major complications (internal hernias requiring reoperation) in the LGBP group that did not reach significance. Minor complications were comparable. %EWL was significantly better in the Laparoscopic gastric bypass group at 3, 6, and 9 months, but was comparable to the OGBP group at 1 year (Laparoscopic gastric bypass/open gastric bypass, 69%/65%). BMI at 1 year was also similar (29 vs. 31). LGBP patients returned to normal activities sooner and had equivalent QOL outcomes. Conclusion Laparoscopic gastric bypass provides certain advantages over open gastric bypass techniques. LOS and time to return to normal activities are shorter and early weight loss results may be superior. Source: Laparoscopic Bariatric Surgery to Reduce Obesity |
