Laparoscopic Adjustable Gastric Banding with the Adhesix® Bioring® for Weight Regain or Insufficient Weight Loss After a Roux-en-Y Gastric Bypass: Midterm Data from the Pronto Registry.

PURPOSE Although Roux-en-Y gastric bypass (RYGB) is one of the most common bariatric procedures, insufficient weight loss is described to be as high as 20-35%. To treat weight regain/inadequate weight loss, laparoscopic adjustable gastric banding (LAGB) could be a feasible revisional strategy. MATERIALS AND METHODS We report on a prospective study which included 35 patients who presented inadequate weight loss or significant weight regain after primary RYGB (percentage excess weight loss [%EWL] at revision < 50%). All patients underwent revisional LAGB with the placement of an Adhesix® Bioring® adjustable gastric band (Cousin Biotech, Wervicq-Sud, France). Patients' weight loss, complications, frequency of revisions and quality of life were evaluated. RESULTS Follow-up data at 24 months are available for 80% of the included patients. The mean BMI before RYGB was 43.6 ± 5.4 kg/m2 and before revisional LAGB was 38.8 ± 4.3kg/m2. The %EWL before revisional surgery was 23.3 ± 24.8%. The average time between both procedures was 6.7 (mean) ± 3.6 (SD) years. Twenty-four months after revisional LAGB, the average BMI calculated from the weight at RYGB dropped to 32.0 ± 4.5 kg/m2, with an additional %EWL of 49.9 ± 30.3% resulting in a total %EWL of 60.7 ± 28%. The reoperation rate for complications related to LAGB was 21.2%. No band erosions occurred, but two bands needed to be removed during the study. CONCLUSION Revisional LAGB may be considered a valid salvage procedure in patients with weight regain or inadequate weight loss after RYGB, though band- and port-related complications remain a notable concern.
