Purpose: This study investigates whether pharmacotherapy with liraglutide is similarly effective in reversing weight regain more than 6 years after Roux-en-Y gastric bypass (RYGB) as revisional surgery aimed at restoring restriction. Methods: Ninety-five consecutive patients (11 male, 84 female; mean BMI 45 ± 6 kg/m2) undergoing RYGB 9 ± 4 years ago were treated for 24 months as follows: Patients, who gained less than 10% from weight NADIR, served as controls and were provided lifestyle counseling (DC, n = 30). The others were allowed to choose between three different treatment groups: daily s.c. administration of liraglutide (LG, n = 34); endosurgery using Apollo's Overstitch System™ (ES, n = 15), or implantation of a Fobi-ring with pouch resizing (FP, n = 16). Results: Controls kept their weight stable during 24 months of study (− 0.1 ± 1.7 kg/m2). Weight loss was 4.8 ± 2.9 kg/m2 for LG and 5.5 ± 2.9 kg/m2 for FP, both losing more than 85% of regained weight from weight NADIR (p < 0.001). In contrast, weight loss in ES was 1.0 ± 0.9 kg/m2 (i.e., 20% of regained weight). Thirty-seven percent of FP experienced serious complications (p < 0.05) in contrast to the other groups. An improved prevalence of hypertension and dyslipidemia was observed in LG and FP (p < 0.02) 24 months after intervention. Conclusions: Weight regain during more than 6 years after RYGB can be safely and effectively reversed with liraglutide. Compared with revisional surgery, pharmacotherapy with liraglutide was low risk and resulted in an important improvement in hypertension and dyslipidemia. Therefore, daily subcutaneous injections of liraglutide are a valid option to treat weight regain after RYGB. [ABSTRACT FROM AUTHOR] |
