With regards to metabolic and bariatric surgery performed in East Asia, which ONE of the following is most commonly performed?
Correct Answer: D
Rationale: In East Asia, sleeve gastrectomy (SG) has emerged as the most common bariatric surgery, surpassing Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB), per regional data and trends. SG's popularity stems from its technical simplicity, lower complication rates, and effectiveness in weight loss and metabolic improvement, appealing in populations with lower average BMI but high visceral fat, like Asians. RYGB, while effective, is less favored due to complexity and malabsorption risks. AGB has declined globally due to less sustained outcomes. Mini-gastric bypass is rising but not dominant. SG's prominence reflects practical and cultural fit, informing physicians on regional preferences for obesity management.
