Phase 4 Trial.
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 (NCT07859137). This is a study registration, not published results. Lead sponsor: General Committee of Teaching Hospitals and Institutes, Egypt. Recruitment status: NOT_YET_RECRUITING. Phase: PHASE4. Study type: INTERVENTIONAL. Enrollment: 100 participants (ESTIMATED). Conditions: Morbid Obesity. Interventions: DRUG: Semaglutide weekly injection; DRUG: Placebo. Primary outcome measures: Mean operative difficulty score , At the time or during surgery. Brief summary: Patients with BMI 60 kg/m² or higher are the hardest operations in bariatric surgery. Thick abdominal wall, massive hepatomegaly, reduced working space, fragile fatty tissue, higher conversion and complication rates. Every bariatric surgeon knows this group. Almost no trial recruits it. The standard answer is a short liver-reduction diet before surgery. It helps, but the effect is modest, hard to tolerate, and short-lived. GLP-1-based drugs now produce far larger and better-tolerated weight loss and are already being given before surgery in routine practice, without trial evidence. Retrospective series show more preoperative weight loss and no obvious harm, and no more than that (Obesity Research \& Clinical Practice 2026). A 2023 review of drugs on the surgical waiting list found that GLP-1 receptor agonists had never been evaluated for the preoperative indication at all. Two registered trials are now adjacent to this question, and we cite both. The PreMO pilot randomizes 50 patients to open-label preoperative tirzepatide versus standard care, with tissue inflammation as the scientific focus (PMID 41643256; NCT06721507). A three-arm trial before one-anastomosis gastric bypass compares tirzepatide, ketogenic diet, and standard care, with weight loss at one year as primary (NCT07622992). Neither is blinded. Neither recruits BMI 60 and above. Neither measures whether the drug actually makes the operation easier and safer. The 2024 IFSO international consensus reached 100% agreement that evidence is insufficient to recommend routine preoperative medication, that use must be individualized, and that more research on benefits, risks, and outcomes is required; it also agreed, at 97%, that adequate protein and resistance exercise must accompany any preoperative drug treatment (PMID 39612579). This trial is the research that consensus calls for, and its preoperative program is built to the 97% requirement.
