Gastric bypass reduces risk of birth defects

Children born to women who underwent gastric bypass surgery before becoming pregnant had a lower risk of major birth defects than children born to women with severe obesity at the start of their pregnancy, according to a matched cohort study by researchers at Karolinska Institutet and Örebro University, Sweden.

Treating adolescent obesity - the evidence behind the options

As rates of adolescent obesity continue to rise, choice of treatment needs to be guided by the severity of obesity, psychosocial factors, comorbidities and patient's age and pubertal status, according to a paper published in the Journal of the American Medical Association.

Increase in psychiatric illness presentations after bariatric surgery

Researchers from Australia have reported an increase in mental health service presentations after bariatric surgery, particularly among those who had prior psychiatric illnesses or developed surgical complications requiring further surgery.

Large-scale ERP improves outcomes for bariatric surgery patients

A large-scale implementation of a protocol to improve recovery of patients after weight-loss operations was found to reduce rates of extended hospitalisation by almost half at 36 participating accredited bariatric surgery centres in the US. The study compared outcomes of 8,946 bariatric operations before with 9,102 operations that occurred after implementation of the protocol, known as an enhanced recovery program (ERP).

Women more likely to use post-op contraception after counselling

A study from the Netherlands examining contraceptive use pre- and post-operatively in women who underwent bariatric surgery has reported that 60% of women are using safe contraception post-operatively. However, only 62.6% of patients recall receiving contraceptive counselling but, the investigators noted, they were more likely to use safe contraception after surgery. Therefore, the authors recommended more counselling and monitoring in the post-operative and outpatient setting.

Weight loss prior to surgery may not be safe for all patients

Weight loss prior to metabolic and bariatric surgery may not be necessary for all patients and unsafe weight loss prior to surgery may compromise nutrition status and lead to increased infection rates, according to researchers from the University of Pennsylvania.

Bariatric surgery eligibility should consider more than just weight

Forty-five worldwide scientific and medical societies are pushing to change national guidelines that would allow more patients with the chronic diseases of obesity and diabetes to be eligible for bariatric surgery. As chronic obesity worsens, it comes not only with complications of diabetes, but may also include heart disease and cancer. Just like with any other chronic disease, the best course of action is early intervention, such as bariatric surgery.

Bariatric surgery patients at higher risk of death from substance abuse

The death rate from drug- and alcohol-related causes in patients who have had Roux-en-Y gastric bypass surgery is nearly triple that of the general public, according to University of Pittsburgh researcher. The study also found that fewer than half of those who died had triggered a safety protocol for problematic substance use. Only one of those who died was known to have received treatment for substance use disorder.

Bariatric surgery reduces the development of colorectal lesions

Bariatric surgery was associated with fewer incidences of new colorectal lesions in patients undergoing bariatric surgery compared with a control group not undergoing bariatric surgery, according to researchers from University of Virginia, Charlottesville, VA.

Bariatric surgery is cost-effective treatment for patient with T2DM

Performing bariatric surgery in patients with morbid obese with type 2 DM is a cost-effective strategy in Thailand, according to researchers from King Chulalongkorn Memorial Hospital (KCMH) and Thammasat University, Bangkok, Thailand. The authors note that although the evidence suggests that bariatric surgery is a successful long-term treatment in patients with morbid obese with type 2 DM, it is an expensive procedure with additional costs possible in the months following surgery. Therefore, they wanted to assess whether bariatric surgery is cost-effective in this group of patients.
