Primary Outcome Measures
NameTimeMethod
the percentage of total weight loss (%TWL) of the patients after surgeryBaseline, 1 year, 3 year, 5 year after SADI-S and OAGBP surgery
Secondary Outcome Measures
NameTimeMethod
% of patients with gastroesophageal reflux (acid and bile) after surgery1 year, 3 year, 5 year after SADI-S and OAGBP surgery
Number of Participants with complications in the immediate postoperative periodup to day 90 post-intervention
Number of patients with nutritional deficiencies1 year, 3 years, 5 years after SADI-S and OAGBP surgery

The main nutritional deficiencies to be evaluated after OAGB (One Anastomosis Gastric Bypass) and SADIS (Single Anastomosis Duodeno-Ileal Switch) are iron and/or vitamin B12 deficiency anemia, deficiencies in fat-soluble vitamins, calcium, and trace elements.

The incidence of nutritional deficiencies will be assessed through routine blood tests at 1 year, 3 years, and 5 years after the surgery

Number of deaths in the immediate postoperative periodup to day 90 post-intervention
Ratio of patients with more than 3 loose stools per day1 year, 3 years, 5 years after the surgery

The ratio of patients with more than 3 loose stools per day will be evaluated as pathological. To assess the quality of the bowel movements, the Bristol Stool Form Scale questionnaire will be used. An evaluation of the number of bowel movements and their quality according to the Bristol Stool Form Scale questionnaire will be conducted at 1 year, 3 years, and 5 years after the surgery

questionnaire of quality of life1 year, 3 years, 5 years after SADI-S and OAGBP surgery

The quality of life will be assessed based on the results of the Moorehead-Ardelt II test and the Medical Outcomes Study Short Form-36 questionnaire. The Moorehead-Ardelt II questionnaire includes 6 parameters related to self-esteem, physical activity, social contact, job satisfaction, sexual pleasure, and eating habits. The minimum score is -3 and the maximum is +3. A score of 1.1 to 2 is considered a good result, and anything above 2.1 is considered very good.

The SF-36 questionnaire includes 8 parameters such as physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health. The minimum score is 0 and the maximum is 100.
