MiniMizer Ring comes to Latin America

It was a great pleasure to come to Chile and perform the first Banded Gastric Bypass procedures done with the Minimizer Gastric Ring in Latin America with Dr Juan Eduardo Contreras Paraguez and his great OR team. Together with Dr Luc Lemmens these surgeries went great and the patients are back on their weight loss journey.

    RCT Primary Banded Gastric Bypass starts in Arnhem/the Netherlands

    In March 2015 Dr. Berends et al. received approval from the Medical Ethics Committee to start a prospective randomized controlled trial, comparing 75 patients with primary banded gastric bypass to 75 patients with primary non-banded gastric bypass.

    For 3 years both groups will be followed up intensively and various critical parameters (EWL, resolutions of co-morbidities, complications, etc.)will be monitored.

    RCT Primary Banded Sleeve Gastrectomy starts in Freiburg/Germany

    In February 2015 Dr. Fink et al from the University Hospital in Freiburg started a prospective randomized controlled trial comparing 70 patients with primary banded sleeve gastrectomy to 70 patients with primary non-banded sleeve gastrectomy. Follow up period will be 3 years.

    In an initial study with 25 patients it was noted that the tight placement of the rings with a diameter of 6.0cm induced too high a level of erosion and migration. The width of the rings in the new study will be 7,5cm to avoid this issue.

    MiniMizer Gastric Ring

    In banded gastric bypass and banded gastric sleeve a non-adjustable gastric ring should be used which should be easy to place. more

    Minimizer Extra Gastric Band

    The MiniMizer Extra gastric band has two closing positions and loops on the side, which allow for direct fixation, avoiding the use of a gastro-gastric plication. more
