Abstract
Background
Metabolic and bariatric surgery (MBS) is the most effective treatment for obesity and improvement of obesity-associated comorbidities. However, a proportion of these patients may suffer from weight recurrence and recurrence of obesity-associated comorbidities.
Method
A retrospective cohort study of patients who underwent SG between January 2008 and August 2022 and sought treatment for weight recurrence with semaglutide or tirzepetide from January 2022 onwards.
Result
A total of 115 patients were included, of which 70 had SG and treated for weight recurrence with semaglutide and 45 had SG and treated with tirzepatide. The mean age of patients was 38.8 (10.4) and 80.9% of patients were female. The mean pre-treatment weight and BMI was 94.0 (23.8) kg and 35.1 (6.0) kg/m2. Following treatment with semaglutide and tirzepatide, the mean post-treatment weight at 6 months was 81.0 (19.0) kg from 90.1 (19.6) kg and 87.6 (28.3) kg from 100.2 (28.5) kg respectively, corresponding to a clinically significant mean weight loss from baseline to 6 months of 10.3 (5.9)% (p < 0.05) and 15.5 (6.3)% (p < 0.05). Weight loss in tirzepatide patients was significantly greater than the semaglutide patients at 6 months (p < 0.02). There were no reported severe adverse events to the treatment.
Conclusion
Short-term outcomes show that semaglutide and tirzepatide can be an effective treatment for managing weight recurrence after SG. Studies with longer follow-up are needed to determine the durability, as weight regain after discontinuation of the medication is highly likely, and the high cost of these medications can limit their use.

Key Points
• This study adds to the current body of evidence supporting the clinical effectiveness of semaglutide and tirzepatide for weight reduction in patients with obesity, particularly in those with weight recurrence following sleeve gastrectomy (SG).
• Weight loss was significantly greater in the tirzepatide-treated group than the semaglutide-treated group.
• A meaningful weight loss may be achieved with the use of pharmacotherapy in patients with weight recurrence after SG without the need for revisional surgery.
• Pharmacotherapy can be an effective alternative to revisional surgeries with minimum adverse effects.
