A retrospective cohort study comparing different fixation methods for the MiniMizer Extra adjustable gastric band.

INTRODUCTION

Two decades ago, laparoscopic adjustable gastric banding was a leading bariatric sur‑ gery. However, its popularity has declined, with sleeve gastrectomy becoming the predominant choice. The MiniMizer Extra band used in our clinic from 2008 to 2020 was associated with band erosion primarily at its lower edge. In 2014, we started using a modified band fixation technique by placing sutures only on the upper part of the band.

AIM

The aim of this study was to compare 2 different fixation techniques for the MiniMizer Extra adjustable gastric band to identify any potential differences in outcomes.

MATERIALS AND METHODS

In this study, we compared 54 patients who underwent adjustable gastric banding with the MiniMizer Extra band between January 1, 2009, and January 31, 2010, with a group of 54 patients who were subjected to the procedure between January 1, 2014, and January 31, 2019, using a different band fixation method.

RESULTS

Weight loss results significantly favored the modified fixation group, with an average total weight loss of 24.2%. The overall complication rate was 12% and was significantly higher in the original fixation group. Complications included 6 cases of band erosion, 4 port‑related issues, 1 case of band slippage, and 2 cases of band intolerance.

CONCLUSIONS

The modified fixation group demonstrated improved weight loss results with fewer com‑ plications, suggesting a potential advantage in safety and efficacy of the modified technique.
