Obesity surgery: Which procedure should we choose and why?

Area of Science:

• Bariatric Surgery
• Obesity Management
• Metabolic Surgery

Background:

• Bariatric surgery has evolved over 70 years with four accepted procedures: adjustable gastric banding (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and bilio-pancreatic diversion (BPD).
• Each procedure has distinct risk profiles and outcomes, influencing their clinical application.

Purpose of the Study:

• To compare the effectiveness and safety of major bariatric surgical procedures.
• To guide the selection of bariatric surgery based on patient-specific factors and desired outcomes.

Main Methods:

• Comparative analysis of existing bariatric surgical procedures.
• Review of short-term and long-term complication rates, re-operation rates, and effectiveness in weight loss and comorbidity remission.

Main Results:

• Sleeve gastrectomy (SG) is now the most common procedure, with RYGB as a standard. Both SG and RYGB show comparable weight loss and type-2 diabetes remission, superior to AGB.
• Procedures with longer intestinal bypass, like bilio-pancreatic diversion (BPD) and omega bypass, offer greater weight loss but increased side effects.
• Adjustable gastric banding (AGB) has low initial risk but high re-operation rates; RYGB has higher early complication risks than SG.

Conclusions:

• Procedure selection requires balancing benefit-risk ratios, considering patient BMI and comorbidities.
• Long-term success in obesity management involves both surgical choice and crucial patient behavioral factors.
• Obesity is a chronic disease necessitating comprehensive, long-term medical and surgical management strategies.
