Effect of BAriatric Surgery Versus Optimal Medical Therapy on Cardiovascular Health and Atherosclerosis in Obese, Type II Diabetic Patients (BASTA)
January 5, 2015 updated by: Geltrude Mingrone, Catholic University of the Sacred Heart
Prospective Randomized Controlled Trial on the Effect of BAriatric Surgery Versus Optimal Medical Therapy on Cardiovascular Health and Progression of Atherosclerosis in Obese, Type II Diabetic Patients
To assess the impact of weight loss due to bariatric surgery, as compared to the effect of optimal medical therapy alone on endothelial function, subclinical atherosclerosis, cardiovascular autonomic function in obese patient affected by type 2 diabetes.The study consists in a 2-arm randomized trial, in which patients will be randomly assigned to bariatric surgery or optimal medical therapy.
Each patient will be studied at baseline (T0) and 12 months thereafter (T1).

Description
Inclusion Criteria:
- type 2 diabetes: the American Diabetes Association (ADA) recommends the following criteria for diagnosis of diabetes: HbA1c ≥6.5% OR fasting plasma glucose‡ ≥126 mg/dL (7.0 mmol/L) OR 2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) during an oral glucose tolerance test; 75-g glucose load should be used OR random plasma glucose concentration ≥200 mg/dL (11.1 mmol/L) in persons with symptoms of hyperglycemia or hyperglycemic crisis;
- indication to bariatric surgery: BMI ≥35 kg/m2 and one or more obesity related co-morbidities, including Type 2 Diabetes Mellitus.
Exclusion Criteria:
- overt cardiovascular disease (as assessed by clinical evaluation, physical examination, 12-lead ECG, 2D-echocardiogram);
- smoking habit;
- associated medical conditions, as chronic kidney disease (defined as creatinine clearance <60 mL/min/L.73m2), liver cirrhosis, malignancies, chronic congestive heart failure, acute or chronic inflammatory disease;
- specific contraindication to bariatric surgery;
- pregnancy;
- medical conditions requiring acute hospitalization;
- psychological conditions which may hamper patient's cooperation;
- geographic inaccessibility.

Experimental: Bariatric Surgery
Gastric bypass
|
A subcardial gastric pouch with a 30±10 ml capacity will be created by sectioning the stomach with a linear stapler 3-4 cm horizontally on the lesser curve, 4 cm distal to the e-g junction, and then vertically until attainment of the angle of Hiss.
After identification of the Treitz ligament, the jejunum will be transected at 100 cm from the ligament of Treitz and the two stumps will be closed.
The distal stump will be anastomosed to the distal end of the gastric pouch.
The preferred gastro-jejunal anastomosis is the totally hand-sewn one, but it can be performed using any other the technique the surgeon is more familiar with.
Finally, the proximal stump of the transacted bowel will be joined end-to-side to the jejunum 150 cm distal to the gastro-enterostomy.
