LSG Patient Cohort Demographics and Weight Loss Outcomes, 2008-2022

Demographic and clinical data for 120 laparoscopic sleeve gastrectomy patients from the MBSAQIP registry between 2008 and 2022. The dataset was created by author Sofia Yeremian to study the relationship between preoperative psychological evaluations and long-term weight loss. It compares average percent weight loss for patients with and without psychological evaluations.

Use Cases

• Compare long-term weight loss outcomes based on preoperative psychological evaluation status.
• Analyze demographic makeup of a laparoscopic sleeve gastrectomy patient cohort.
• Investigate the potential impact of clinical guidelines on patient care pathways.

Strengths

• Data is sourced from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) registry.
• Includes a specific comparison of average percent weight loss (27.76% vs. 29.42%) for two patient groups.
• Covers a 14-year time range from 2008 to 2022.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Dataset is very small at 5.5 KB, indicating limited scope and sample size.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
