Transcription

1 Bariatric Surgery Devices - Global Pipeline Analysis, Competitive Reference Code: GDME0152MAR Publication Date: July 2012 The Global Bariatric Surgery Devices Market is Forecast to Reach $XX Billion by 2018 Bariatric Surgery Devices Market, Global, Revenue ($bn), Revenue ($bn) CAGR ( ): XX% There are marked differences in the trends related to gastric bypass and gastric banding procedures in the US and European countries. In the US, the number of gastric banding procedures being conducted is on the rise whereas in European countries the number is declining. In the US, gastric banding procedures started about 10 years later than in Europe and were performed using modern efficient devices. Surgeons therefore had a better first experience with the surgery and quickly adopted it. Factors such as gastric banding being less invasive, less risky and resulting in shorter hospital stays also favored the growth of these procedures in the US. Sleeve gastrectomy procedures are also on the rise in the US due to their safety and efficacy. Ethicon Endo-Surgery Remains the Leading Player in the Global Bariatric Surgery Devices Market Source: GlobalData analysis based on primary research with 17 marketing and product development managers and bariatric surgeons in Asian, European and North American markets Bariatric Surgery Devices Market, Global, Company Share (%), 2011 Ethicon Endo-Surgery The global bariatric surgery devices market was valued at $XX billion in 2011 and is forecast to grow at a Compound Annual Growth Rate (CAGR) of XX% to reach $XX billion in The market is expected to be driven by the increasing prevalence of obesity, failure of medicines to treat obesity, availability of reimbursement, increasing awareness about the risks associated with obesity and advantages of bariatric surgery, increasing number of bariatric surgery procedures among adolescents, and the cost-effectiveness of bariatric surgery in the long term. The US Remains the Largest Bariatric Surgery Devices Market, Driven by the Increase in the Prevalence of Obesity The US bariatric surgery devices market was valued at $XXm in 2011 and is expected to grow at a CAGR of XX% to reach $XX billion in This growth is expected to be driven by the increasing prevalence of obesity and increasing number of gastric banding and sleeve gastrectomy procedures in the US.

6 2 Introduction Obesity can be defined as buildup of excessive fat in the body which poses a risk to the person s health. Body Mass Index (BMI) is a useful measure as it determines whether a person is overweight or obese based on their height and weight. According to the World Health Organization (WHO), an adult with a BMI of XX or more is considered overweight and a person with a BMI of XX or more is considered obese. Bariatric surgery or weight-loss surgery is suggested as a primary treatment for obesity if the patient s BMI is more than or equal to XX, or if it is between XX and XX and the patient is suffering from weightrelated diseases such as diabetes or high blood pressure. Three types of bariatric surgeries are covered under the scope of this report: Gastric bypass Gastric banding Sleeve gastrectomy 2.1 GlobalData Report Guidance The report includes an executive summary detailing the key points in the global bariatric surgery devices market.

The devices include gastric bands, stapling devices and trocars Gastric Bands Gastric bands are used in gastric banding surgeries to reduce the size of the stomach s opening. The band is connected to a port which is placed just under the patient s skin and then used to inflate the band, restricting the size of the stomach s opening Stapling Devices Stapling devices are used in gastric bypass procedures to create a small pouch, and in sleeve gastrectomy procedures to create a banana-shaped sleeve. Page 73

10 Trocars Trocars are used during laparoscopic bariatric surgeries to gain access to the patient s abdomen. Depending upon the procedure, five to seven trocars are needed. 9.2 Abbreviations ADA: American Diabetes Association ASMBS: American Society for Metabolic and Bariatric Surgery BMI: Body Mass Index CAGR: Compound Annual Growth Rate C.H.O.I.C.E.: Choosing Health over Obesity Inspiring Change through Empowerment CDC: CMS: DBS: FDA: GE: HSE: IFSO: IGB: ILS: Centers for Disease Control and Prevention Centers for Medicare Services Deep-brain Stimulation Food and Drug Administration Gastroesophageal Health Survey for England International Federation for the Surgery of Obesity and Metabolic Disorders Intragastric Balloon Intraluminal Stapler JAMA: Journal of the American Medical Association LABG: Laparoscopic Adjustable Gastric Banding NHANES: National Health and Nutrition Examination Survey NHS: NOO: OSSI: PEG: National Health Service National Obesity Observatory Obesity and Metabolic Surgery Society of India Percutaneous Endoscopic Gastrostomy RYGBP: Roux-en-Y Gastric Bypass SOARD: Surgery for Obesity and Related Diseases WHO: World Health Organization 9.3 Sources American Society for Metabolic & Bariatric Surgery (ASMBS) (2012).
