Actual (reported)Obesity remains a major global health challenge, with Class IV super obesity (BMI ≥ 50 kg/m²) being the most severe form. This condition is associated with numerous comorbidities including type 2 diabetes, hypertension, obstructive sleep apnea, and hyperlipidemia, which significantly reduce life expectancy and quality of life. Bariatric surgery, particularly sleeve gastrectomy (SG), has been shown to be an effective treatment for morbid obesity. While SG results in significant weight loss and improvement of comorbidities, some patients experience weight regain over time. Banded sleeve gastrectomy (BSG) has been proposed as a modification of SG to enhance long-term outcomes by providing additional restriction via a polypropylene band around the proximal gastric pouch. Although initial evidence for banded procedures suggests improved outcomes, particularly in the context of weight loss and reduced weight regain, specific evidence for Class IV obesity remains limited.
