Perioperative Coordination Between Pharmacotherapy and Bariatric Surgery
The comparative evaluation of bariatric surgery and glucagon-like peptide-1 (GLP-1) receptor agonists demonstrates that these therapeutic modalities provide complementary rather than mutually exclusive clinical pathways in comprehensive metabolic management (Obesity Treatment With Bariatric Surgery vs GLP-1 Receptor Agonists, 2025). Clinical evidence confirms that incretin-based pharmacotherapy yields significant therapeutic utility when managing insufficient weight loss or secondary weight regain following metabolic interventions, solidifying the role of pharmacotherapy as a key post-surgical adjunctive strategy (The Efficacy of Glucagon-like Peptide-1 (GLP-1) Receptor Agonists for Insufficient Weight Loss or Regain After Metabolic/Bariatric Surgery: A Systematic Review and Meta-analysis, 2025). Nevertheless, the clinical transition between pharmacological therapy and surgical interventions introduces substantial perioperative considerations. The pharmacological inhibition of gastric motility characteristic of incretin therapies generates heightened risks of pulmonary aspiration and delayed gastric emptying during anaesthetic induction, requiring heightened vigilance from surgical teams (The widespread adoption of glucagon-like peptide-1 receptor agonists in the management of obesity and its implications for the anaesthesiologist and intensivist: A narrative review, 2025). A pronounced research gap exists concerning unified protocols for preoperative medication withholding intervals and safe postoperative re-escalation, especially within centralized public reimbursement frameworks. Furthermore, key methodological limitations in current scholarship stem from the preponderance of retrospective observational designs and non-standardized anaesthetic reporting across clinical centers. Establishing robust, multidisciplinary consensus guidelines remains essential to harmonize surgical and pharmacological pathways safely.
