Clinical Scorecard: Analysis of Global Patterns and Research Focus in Gastric Bypass Clinical Trials: A Bibliometric and Latent Dirichlet Allocation Study

At a Glance

CategoryDetail
ConditionSevere obesity
Key MechanismsGastric restriction, alterations in intestinal transit, hormonal modulation
Target PopulationIndividuals with severe obesity (BMI ≥ 40 kg/m²)
Care SettingClinical trials and metabolic bariatric surgery

Key Highlights

  • MBS is the reference standard treatment for severe obesity.
  • Gastric bypass (GB) is one of the oldest and most widely performed MBS procedures.
  • Patients may achieve up to a 57% reduction in total body weight five years post-surgery.
  • The number of MBS procedures has increased from 100,092 in 2014 to 598,736 in 2023.
  • Over 72,000 publications on gastric bypass were retrieved from major databases.

Guideline-Based Recommendations

Diagnosis

  • Clinical trials should focus on patients undergoing Roux-en-Y gastric bypass.

Management

  • MBS procedures should be considered for individuals with severe obesity.

Monitoring & Follow-up

  • Long-term weight loss and metabolic improvement should be assessed post-surgery.

Risks

  • Potential comorbidities include type 2 diabetes mellitus and hypertension.

Patient & Prescribing Data

Adults with class III obesity (BMI ≥ 40 kg/m²)

MBS, particularly GB, is effective for sustained weight loss and metabolic disease improvement.

Clinical Best Practices

  • Utilize clinical trials to evaluate the efficacy and safety of gastric bypass.
  • Adopt evidence-based practices in the implementation of MBS.
