The study showed that older patients experienced less weight loss and far more complications than younger patients, indicating that the risks often outweigh the benefits of these types of surgeries in older patients. The study, which appears in the Archives of Surgery, reviewed more than 25,000 bariatric procedures from a national database.
“Adverse outcomes increased with age, particularly after age 60,” said Dr. Edward Livingston, chairman of GI/endocrine surgery at UT Southwestern and the study’s lead author. “Beyond 65 years of age, the adverse event rate exceeded 20 percent and mortality was 3.23 percent.”
In addition to age, the study found that men and those with electrolyte disorders and congestive heart failure were at greater risk of death from bariatric surgery or related complications, said Dr. Livingston.
Other conditions that increased risk for adverse events and required longer hospital stays included chronic pulmonary disease, diabetes and depression.
Common complications included gastrointestinal, respiratory and cardiac problems. Gastrointestinal problems were most common, occurring in about 30 percent of older patients who had complications. Respiratory-tract problems occurred in about 20 percent of patients with post-operative problems. Cardiac complications affected about 15 percent of elderly patients.
The Centers for Disease Control and Prevention estimates that nearly one-third of adult Americans – more than 60 million people – are obese. Nearly 5 percent of adults are classified as extremely obese. The American Society for Bariatric Surgery Foundation estimates that more than 1,000 people die each day from obesity-related complications. Obese adults are at increased risk of diabetes, hypertension, stroke and even some cancers.
Obesity ranges from mild (20 to 50 pounds overweight) to morbidly obese (more than 100 pounds overweight). Bariatric surgeries are usually reserved for those more than 100 pounds overweight.
This latest study reviewed 25,428 bariatric procedures involving Medicare beneficiaries using the National Inpatient Survey database, which contains discharge information for 20 percent of all hospitalizations in the United States, a sufficiently large enough population to overcome limitations of previous studies.
UT Southwestern is one of the few institutions in the nation that offers all types of bariatric procedures and is a regional referral center and leader in bariatric surgery, having performed the area’s first lap band procedures and robotically assisted lap band procedures. UT Southwestern bariatrics programs have garnered national recognition as well, being named bariatric surgery Centers of Excellence by the American Society for Bariatric Surgery and United Resource Networks’ Clinical Sciences Institute.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
