Laparoscopic Adjustable Gastric Banding versus Open Vertical Banded Gastroplasty: A Prospective Randomized Trial (original) (raw)

Background: Laparoscopic adjustable gastric banding (LAGB) and open vertical banded gastroplasty (VBG) are treatment modalities for morbid obesity. However, few prospective randomized clinical trials (RCT) have been performed to compare both operations. Methods: 100 patients (50 per group) were included in the study. Postoperative outcomes included hospital length of stay (LOS), complications, percent excess weight loss (%EWL), BMI and reduction in total comorbidities. Follow-up in all patients was 2 years. Results: LOS was significantly shorter in the LAGB group. 3 LAGB were converted to open (1 to gastric bypass). Directly after VBG, 3 patients needed relaparotomies due to leakage, of which one (2%) died. After 2 years, 100% follow-up was achieved. BMI and %EWL were significantly decreased in both groups but significantly more in the VBG group compared to the LAGB group (31.0 kg/m2 and 70.1% vs 34.6 and 54.9% respectively). Co-morbidities significantly decreased in both groups in time. 2 years after LAGB, 20 patients needed reoperation for pouch dilation/slippage (n=12), band leakage (n=2), band erosion (n=2) and access-port problems (n=4). In the VBG group, 18 patients needed revisional surgery due to staple-line disruption (n=15), narrow outlet (n=2) or insufficient weight loss (n=1). Furthermore, 8 VBG patients developed an incisional hernia. Conclusion: This RCT demonstrates that, despite the initial better weight loss in the VBG group, based on complication rates and clinical outcome, LAGB is preferred. It had a shorter LOS and less postoperative morbidity.
