Multicriteria neutrosophic method to evaluate the gastric sleeve vs. gastric ByPass for the treatment of morbid obesity.

Abstract

Obesity is a complex and multifactorial condition involving genetic and environmental components, characterized by excessive accumulation of body fat. This accumulation can have physiological and pathological effects, increasing morbidity and mortality in adults. The aim of this research is to implement a multicriteria neurosophic method to evaluate gastric sleeve (GS) versus gastric bypass (RYGB) in the treatment of morbid obesity, seeking to determine which of the two bariatric techniques offers better results in terms of weight loss and lower associated risks. Gastric sleeve is associated with significant weight loss, reaching up to one third of body weight in extremely overweight patients. For example, a patient with an initial weight of 300 kg could lose approximately 100 kg. In comparison, Y-shaped gastric bypass also reports considerable losses, with 85% in the first year and 82% at two years. Both procedures not only promote weight loss, but also improve obesity-related health conditions. How- ever, they contain inherent risks and complications; RYGB can present gastric obstructions and bleeding, while MG is associated with nutritional deficiencies, such as iron deficiency. Postoperative care is crucial to ensure favorable outcomes and detect com- plications early.
