Brief Summary:
The aim of the study is to compare the efficacy of laparoscopic gastric bypass versus vertical gastrectomy for the resolution of DM in patients with BMI 30-35.

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: 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.
Masking: Double (Participant, Care Provider)
Masking Description: 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.
Primary Purpose: Treatment
Actual Study Start Date : January 15, 2019
Estimated Primary Completion Date : January 2021
Estimated Study Completion Date : January 2022

Arm Intervention/treatment
Active Comparator: Gastric bypass
Twenty patients will be randomly assigned to perform a laparoscopic gastric bypass.
Procedure: metabolic surgery
The study will randomize patients into two arms, one where a laparoscopic gastric bypass will be performed and another that will perform slevee gastrectomy.

Active Comparator: Slevee gastrectomy
Twenty patients will be randomly assigned to perform a sleeve gastrectomy
Procedure: metabolic surgery
The study will randomize patients into two arms, one where a laparoscopic gastric bypass will be performed and another that will perform slevee gastrectomy.

Primary Outcome Measures :
  1. Number of participans with normal glycosylated hemoglobin levels [ Time Frame: 1 year after surgery ]
    Healing will be defined when HbA1c and fasting glycaemia levels are inside normal limits (Hb1Ac < 6%, FBG<100mg/dl) without needing oral hypoglycemic agents.

Secondary Outcome Measures :
  1. Number of participants with partial remission or improvement of diabetes [ Time Frame: 1 year after surgery ]

    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)

  2. Comparison of weight loss between the two techniques; bypass and sleeve. [ Time Frame: 2 years after surgery ]
    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.

  3. Evaluation of postoperative complications in patients undergoing bypass and slevee with Clavien-Dindo classification. [ Time Frame: 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.

  4. Comparison postoperative pain in sleeve and bypass with analogue assessment scale of postoperative pain. [ Time Frame: 3 days postoperative ]
    The postoperative pain of the patients during the first three postoperative days will be evaluated with the visual analogue scale from 0 (no pain) to 10 (unbearable pain).
