Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07872397). This is a study registration, not published results. Lead sponsor: Hospitales Universitarios Virgen del Rocío. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 68 participants (ESTIMATED). Conditions: Obesity, Morbid. Interventions: PROCEDURE: Single Anastomosis Sleeve Ileal Bypass; PROCEDURE: Roux-en-Y Gastric Bypass. Primary outcome measures: Glycemic Variability Assessed by Glucose Coefficient of Variation , Baseline, 6 months, and 12 months after surgery. Brief summary: The GLUBARI trial is a prospective, randomized, single-center clinical study comparing two bariatric surgical procedures in adults with morbid obesity: Single Anastomosis Sleeve Ileal Bypass (SASI) and Roux-en-Y Gastric Bypass (RYGB). The main objective is to compare glycemic variability between the two procedures using continuous glucose monitoring. Participants will undergo continuous glucose monitoring for 7 days before surgery and again at 6 and 12 months after surgery. Secondary outcomes include hypoglycemic events, weight loss, resolution of obesity-related comorbidities, postoperative complications, gastroesophageal reflux, nutritional deficiencies, and quality of life. A total of 68 participants will be randomized in a 1:1 ratio to SASI or RYGB and followed for 12 months after surgery.
