Metabolic Surgery; Gastric Bypass vs Sleeve Gastrectomy; Efects Over Type 2 DM With Bad Metabolic Control (MSO1CT) (MSO1CT)

研究概览
详细说明
Hyphotesis Laparoscopic gastric bypass is the elective technique in the face of sleeve gastrectomy to improve or heal type 2 diabetes mellitus in patientes with BMI 30-35 kg/m2.
MAIN AIM:
To compare cure rate through the improvement in glycated hemoglobin and fasting glycaemia after laparoscopic gastric bypass face to sleeve gastrectomy.
SECONDARY AIMS:
To quantify both insulin and oral hypoglycemic agents dose decrease. To measure weight loss and its maintenance during the follow-up in both techniques.
To compare postoperative complications. To compare postoperative pain. To compare follow-up complications.
Matherial and methods. Type of study: Randomized clinical trial double blind with two paralel groups.
RANDOMIZATION. Randomization will be a simple one with Epidat 4.1. A number sequence will be carried out and it will be kept in opaque closed envelopes. The envelope will be opened the operation day and the surgery technique will be decided randomly, according to the randomization sequence. The study will be blinded for patients, who will not know the surgery technique they will go on. Dieticians and Endocrinologists who will follow the patients up after the surgery neither will not know it, so differences in dietary recommendations will not appear with this masking.
Subjects of study The study will rely on patients with Diabetes Mellitus type 2 and grade I obesity with HbA1c higher than 7,5 % (BMI 30-35 kg/m2 and type 2 diabetes with bad glycemic control) detected in Endocrinology and Nutrition Department of Hospital Doctor Peset. Patients will go on bariatric surgery in General and Digestive Surgery Department of the same hospital. Patients who accomplish established inclusion criteria will be recruited until sample size is completed; a minimum 40 patients size is estimated (with a type I error of 5% and a power of 80%) and the will be randomized in two 20 people branches. Investigation will follow The World Medical Association and Declaration of Helsinki guidelines.
Definition of healing and improvement. Healing will be defined when HbA1c and fasting glycaemia levels are inside normal limits without needing oral hypoglycemic agents.
Improvement will be defined when decreasing medication doses for keeping normal fasting glycaemia and level of HbA1c under 6%.
Period of study:
The required one for fulfilling the sample. An inclusion of 40 patients in two years is expected.
Variable-gathering period The patient will be call for attending the external consultation of the Endocrinology and Nutrition Department of Hospital Doctor Peset. Each subject will carry out an initial study with nutritional status assesment, cardiovascular risk factors and comorbidities (hypertension, obstructive sleep apnea, dyslipidemia), as well as discarding secondary causes of obesity. In basal state, 2 days, 3, 6 and 12 months after the surgery, a blood test consisting of biochemical analysis, specific proteins, serum hormones, inmunological markers, full blood count and hemostasis will be made. The patient will carry out dietary intervention and follow-up in each phase of the process.

---|---|---|
Number of participants with partial remission or improvement of diabetes

Partial remission: Subdiabetic hyperglycemia (Hb1Ac 6%-6,4%, FBG 100-125mg/dl) in the absence anti diabetic medication. Improvement: statistically significant reduction in Hb1Ac and FBG not meeting criteria for remission or decrease in anti diabetic medication requirement (by one oral agent, or 1/2 reduction in dose) |

|
To measure weight loss and its maintenance during the follow-up in both techniques.
For this, the patients will be weighed in the postoperative period at month, 3, 6 12 months and then annually.

|
Evaluation of postoperative complications in patients undergoing bypass and slevee with Clavien-Dindo classification.
大体时间:1 month after surgery
|
Grade I: any deviation from the normal postoperative course without the need for pharmacological treatment or surgical, endoscopic and radiological interventions. Allowed therapeutic regimens are: drugs as antiemetics, antipyretics, analgesics, diuretics and electrolytes and physiotherapy. This grade also includes wound infections opened at the bedside. Grade II: Requiring pharmacological treatment with drugs other than such allowed for grade I complications. Blood transfusions and total parenteral nutritional also included. Grade III: Requiring surgical, endoscopic or radiological intervention. Grade IV: Life-threatening complication requiring IC/ICU management. Grade V: Death of a patient. |
