Summary
Bariatric surgery is growing globally, but at a slower rate. Laparoscopic adjustable gastric banding (AGB) and Roux-Y gastric bypass (RYGB) are common, with regional differences in trends.
Area of Science:
- Metabolic and Bariatric Surgery
- Global Health Trends
- Surgical Procedure Epidemiology
Background:
- Bariatric surgery volume requires periodic global assessment.
- The last comprehensive evaluation was in 2003.
- Significant advancements in surgical techniques have occurred since.
Purpose of the Study:
- To assess the global state of bariatric surgery in 2008.
- To identify trends in surgical procedure prevalence.
- To compare procedural trends between regions.
Main Methods:
- Email survey distributed to leaders of 39 national bariatric surgery organizations.
- Tabulation of survey responses.
- Calculation of relative prevalence using weighted averages.
Main Results:
- 344,221 bariatric operations performed globally in 2008.
- Laparoscopic adjustable gastric banding (42.3%) and Roux-Y gastric bypass (39.7%) were most common.
- Significant regional divergence: Europe favored RYGB increase while USA/Canada favored AGB increase.
Conclusions:
- Bariatric surgery continues to grow worldwide, albeit at a reduced rate compared to the previous 5-year period.
- Procedure prevalence is dynamic, with notable opposition in trends between Europe and USA/Canada.
- Laparoscopic approaches dominate, exceeding 90% of all procedures.

01:25Pharmacokinetics in Obese Patients: Drug Absorption and Distribution
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...
01:24Obesity
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
