Outcome Measures

Primary Outcomes (11)

  • Weight change

    Measured as percent of Excess Weight Loss (%EWL) using the following formula: ((weight at each study visit - initial weight) / (initial weight - ideal weight)) X 100

    3 to 60 months after surgery

  • Waist size change

    Waist size (in cm)

    3 to 60 months after surgery

  • Medical and surgical complication

    According to Clavien-Dindo classification

    3 to 60 months after surgery

  • Operative time

    Expressed in minutes

    During surgery

  • Hemoglobin

    Measurement of Hemoglobin will explore the nutritional status of patients. Results will be expressed in g/l

    before surgery up to 60 months after surgery

  • Albumin

    Measurement of albumin will explore the nutritional status of patients. Results will be expressed in g/l

    before surgery up to 60 months after surgery

  • Ferritin

    Measurement of ferritin will explore the nutritional status of patients. Results will be expressed in microg/l

    before surgery up to 60 months after surgery

  • Iron

    Measurement of iron will explore the nutritional status of patients. Results will be expressed in micromol/l

    before surgery up to 60 months after surgery

  • Parathyroid hormone (PTH)

    Measurement of PTH will explore the nutritional status of patients. Results will be expressed in pmol/L

    before surgery up to 60 months after surgery

  • Vitamin B12

    Measurement of vitamin B12 will explore the nutritional status of patients. Results will be expressed in pmol/l

    before surgery up to 60 months after surgery

  • Vitamin D

    Measurement of vitamin D will explore the nutritional status of patients. Results will be expressed in nmol/l

    before surgery up to 60 months after surgery

Secondary Outcomes (10)

  • Fasting glycemia

    before surgery up to 60 months after surgery

  • HbA1c

    before surgery up to 60 months after surgery

  • Triglycerides

    before surgery up to 60 months after surgery

  • Cholesterol

    before surgery up to 60 months after surgery

  • HDL

    before surgery up to 60 months after surgery

  • +5 more secondary outcomes

Study Arms (2)

SASI Bipartition

Subjects submitted to SASI Bipartition

Procedure: SASI Bipartition

Roux-en-Y gastric bypass

Subjects submitted to gastric bypass

Procedure: Gastric bypass

Interventions

SASI Bipartition is performed with a sleeve gastrectomy over a 32 French gastric bougie and a 300 cm common limb. Side-to-side gastroileostomy with a diameter of approximately 2.5 cm at the anterior part of antrum, 6 cm proximal to pylorus.

Also known as: Single-anastomosis Sleeve Ileal Bypass
SASI Bipartition

A small gastric pouch (15 mL) is created, and the jejunum brought up as an antecolic and antegastric fashion. Routine limb lengths were 150 cm for the alimentary limb and 60 cm for the bilio-pancreatic limb. Both mesenteric defects are closed with the Endohernia® stapler.

Also known as: Roux-en-Y gastric bypass
Roux-en-Y gastric bypass
