BACKGROUND AND AIMS: Transoral outlet reduction (TORe) and antiobesity medication (AOM) are effective treatments for weight regain after Roux-en-Y gastric bypass (RYGB). This study aims to assess the efficacy of combination therapy (TORe + AOM) for treating weight regain and to compare the safety and efficacy of combination therapy with AOM alone, TORe alone, and surgical revision of RYGB.
METHODS: This was a retrospective study of RYGB patients with weight regain who underwent combination therapy, defined as initiation of at least 1 AOM within 6 months before or after TORe. Outcomes were weight loss after combination therapy and comparison of combination therapy with AOM alone, TORe alone, and surgical revision.
RESULTS: One hundred forty-five RYGB patients underwent combination therapy. Most commonly prescribed AOMs were topiramate, phentermine/topiramate, phentermine, and liraglutide. At 12 months, patients experienced 15.2% ± 7.4% total weight loss (TWL). Ninety percent of patients achieved ≥5% TWL at 12 months. Combination therapy was associated with greater weight loss than AOM alone (15.2% ± 7.4% vs 6.8% ± 8.2% TWL, P < .0001) or TORe alone (15.2% ± 7.4% vs 8.7% ± 8.3% TWL, P < .0001), with similar serious adverse event rates (2.1% vs 4.7% vs .6% for combination therapy vs AOM alone vs TORe alone, P > .05). Combination therapy yielded similar weight loss to surgical revision (15.2% ± 7.4% vs 16.4% ± 13.1% TWL, P = .34), with a lower serious adverse event rate (2.1% vs 14.3%, P = .0004).
CONCLUSIONS: Combination of TORe with AOM is superior to either therapy alone, providing similar efficacy to surgical revision with a better safety profile for the treatment of weight regain after RYGB.
