A Retrospective Multicenter Comparison of Laparoscopic and Robotic-Assisted Roux-en-Y Gastrectomy
NCT05224791 · View on ClinicalTrials.gov ↗
Study Summary
The prevalence of obesity has tripled in the last 50 years with presently about 1.7 billion of the world population aged 18 years and over either overweight or obese.1 In the US alone, 35% of the population is obese.2 Although alternative surgical approaches are available, bariatric surgery results in substantial and durable weight reduction for the majority of patients, making it the most effective treatment for severe obesity.3 In the battle to reduce the invasiveness of bariatric procedures, laparoscopy has become the gold standard approach for virtually all bariatric surgery procedures in the years since it was first used for gastric bypass by Wittgrove and colleagues in 1993.5 Available data shows perioperative patient-oriented advantages of laparoscopy when compared with open surgery, including a shorter hospital stay, decreased postoperative pain, and enhanced postoperative recovery.6 The Agency for Healthcare Research and Quality (AHRQ) reported significant improvements in the safety of metabolic/bariatric surgery due in large part to improved surgical techniques.7 The risk of death is about 0.1%8 and the overall likelihood of major complications is about 4%.9 Performing bariatric surgery laproscopically can be demanding in many situations because of large livers and substantial visceral fat that limit the working space and make exposure, dissection, and reconstruction difficult.10 Similarly, thick abdominal walls may cause excessive torque on instruments. Under such situations, surgeons' ergonomics become a serious concern.11 Use of robotics in bariatric surgery has been evolving since Cadiere and colleagues reported the first case in 1999.12 Robotic surgery has provided the surgeons with the advantage of three-dimensional vision as well as increased dexterity and precision by downscaling surgeon's movements enabling a fine tissue dissection and filtering out physiological tremor.13 It overcomes the restraint of torque on ports from thick abdominal wall, an

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05224791
The ClinicalTrials.gov registry entry for NCT05224791 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 400 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Methodist Health System, which has 72 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Sleeve Gastrectomy appearing as the primary indexed condition, and to 2 interventions — of which Sleeve Gastrectomy is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT05224791 reports 1 study location spanning 1 distinct geographic area — top geographies include Texas. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
