Laparoscopic adjustable gastric banding results after 2 years with two different band types

Background: Laparoscopic gastric banding is the most common operation in Europe for morbid obesity. Many devices from different companies are now available. The aim of this study was to compare the results over a 2-year period of 2 types of band: the Lap-Band (R) and the Minimizer (R) band. Methods: In a non-randomized study, 2 consecutive groups were prospectively analyzed. Group A consisted of 120 patients who received the Lap-Band (R), and group B consisted of 68 patients who received the Minimizer band which contains eyelets. All the bands were placed above the lesser sac by the perigastric approach. Results: 4 early complications were observed in group A (1 phlebitis, 1 pneumopathy and 2 early displacements of the band); and 1 in group B (1 retention of urine). After a follow-up of 2 years, the displacement rate of the band was 10.8% in group A and 0% in group B. One gastric erosion was observed in group B, but not in group A. After 2 years, the average loss of excess weight was 50% in both groups. Conclusion: With the Minimizer band, we did not observe any slipping, and the efficacy with respect to weight loss was equivalent to the Lap-Band (R).
