Study finds increased fracture risk after Roux-en-Y gastric bypass

Researchers from the Massachusetts General Hospital in Boston, MA, have reported that bariatric surgery is associated with health benefits, however patients undergoing Roux-en-Y gastric bypass (RYGB) have an increased fracture risk and this should be considered when patients are in thinking of undergoing surgery.

Bypass and sleeve beat AGB for adolescents undergoing surgery

Adolescents undergoing Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) have a greater decline in BMI, compared to those who had laparoscopic adjustable gastric banding (AGB), according to researchers reporting outcomes from the PCORnet Bariatric Study (PBS).  In addition, the authors also reported that the majority of patients maintained weight loss over the five-year follow-up time period, while patients undergoing AGB lost the least weight.

RYGB associated with more non-vertebral fractures than AGB

Patients undergoing Roux-en-Y gastric bypass (RYGB) surgery may be at greater risk for non-vertebral fracture than those having adjustable gastric banding (AGB), according to a population-based study by researchers from Massachusetts General Hospital.

Weight regain: Post-op adjuvant weight loss medication is effective

Adjuvant weight loss medications after bariatric surgery can stop weight regain and maintain weight loss, according to a study by researchers from the Bariatric and Metabolic Institute, Department of General Surgery, Cleveland Clinic, Cleveland, OH. The study found that more than one third of patients who received adjuvant weight loss medications achieved>5% weight loss and the response was ‘significantly better’ in gastric bypass and gastric banding patients, compared with sleeve gastrectomy patients.

Surgery reduces usage of anti-diabetes treatment after six years

The six-year outcomes from a French study looking at the discontinuation or initiation of anti-diabetes treatment 6 years after adjustable gastric banding (AGB), gastric bypass (GBP) or sleeve gastrectomy (SG), has reported that bariatric surgery was associated with a significantly higher anti-diabetes treatment discontinuation rate, compared with baseline and with an obese control group without bariatric surgery.

Studies find contrasting outcomes following AGB

Two published papers have report markedly different long term (five years) outcomes following adjustable gastric banding and will further the debate on the benefits and drawbacks of the procedure.

Bariatric surgery associated with increased fracture risk

Bariatric surgery patients are more likely to have increased fracture risks both before and after the surgical procedure, compared to obese and non-obese people who don't need surgery, according to a large study published by The BMJ. Obesity may not be as protective for fracture as originally thought, claim the authors, and they suggest that fracture risk assessment and management should be part of weight loss care.

Bariatric surgery improves lipid profile in obese patients

Bariatric and metabolic surgery can significantly benefit the lipid profiles of patients a year and more after surgery, according to a report published in The American Journal of Medicine. Researchers from the NYU Langone Medical Center, New York, US, made their conclusions after undertaking a meta-analysis of studies on contemporary bariatric surgery outcomes to describe the effects of Bilio-pancreatic Diversion (BPD), Roux-en-Y Gastric Bypass (RYGBP), Adjustable Gastric Banding, and Sleeve Gastrectomy procedures on serum lipids of obese patients at one year and more after surgery.

Short term deficiencies could have long-term consequences

Researchers from Paris, France, have reported that short term nutritional and protein deficiencies following gastric bypass (GBP) and adjustable gastric banding (AGB) could have long-term consequences. The paper, ‘Nutritional and Protein Deficienciesin the Short Term following Both Gastric Bypass and Gastric Banding, published in the journal PlosOne, suggests that patients should be monitored for protein intakes, both before and after the surgery, and that the consumption of protein-rich foods among a balanced diet should be recommended.

Bariatric surgery patients need nutritional education

Patients undergoing bariatric surgery must be continuously educated on proper nutrition so they can avoid the risk of developing significant vitamin B12 deficiencies, according a study from the University of Connecticut, Farmington.
