Introduction: Bariatric surgery has amply demonstrated its benefit in the treatment of morbidly obese patients. After surgery, there is a progressive and significant decrease in weight in a high percentage of patients. Most comorbidities resolve, improving quality of life and increasing life expectancy.Methods and Objective: The literature review is based on a 10-year or longer follow-up of patients who underwent various bariatric surgery procedures. The long-term weight loss results and the clinical impact were evaluated.Results: The applied surgical techniques, including Rouxen-Y gastric Bypass (RYBG), Biliopancreatic Diversion, Scopinaro type (BPD), and Duodenal Switch (DS), have contributed to achieving very satisfactory long-term and sustainable weight loss results. According to the reviewed literature, the percentage of excessive BMI Loss (%EBMIL) for the various techniques was 67.9%, 70.7%, and 71.5% for RYGB, BPD, and DS, respectively. Patients undergoing BGYR have lost much more weight than non-surgical patients and can maintain long-term weight loss, reaching a Percentage of Excessive Weight Loss (%EWL) as high as 56.4% in 10 years.
