Post-RYGB: Mesenteric defect - to close or not to close?

There is no difference in the health-related quality-of-life (HRQoL) outcomes in patients who received mesenteric defect closure after laparoscopic gastric bypass, compared to those patients who did not have their mesenteric defect closed, according to the results of a randomised clinical trial by researchers from Sweden.

Little difference in RYGB vs. banding costs

A study comparing the impact of laparoscopic adjustable gastric banding (AGB) and laparoscopic Roux-en-Y gastric bypass (RYGB) on health care use and costs, has concluded that both procedures were associated with flattened total health care cost trajectories but RYGB patients experienced lower total and prescription costs by three years post-surgery.

Bariatric surgery safe and effective in older patients

A study comparing the outcomes from laparoscopic Roux–en-Y gastric bypass (LRYGB) and sleeve gastrectomy (LSG) in patients aged more than 55 years has concluded that both procedures  achieve good weight loss and resolution of comorbidities, and although bypass is superior in terms of diabetes remission it does have a higher complication rate even at high volume centres.

Surgery has positive impact on adolescent bone density

The skeletons of obese adolescents are usually more dense than those of normal weight teens, but after gastric bypass surgery, most return to normal density within two years, according to a study presented at ENDO 2015, the annual meeting of the Endocrine Society, in San Diego.

Bypass and concomitant hernia repair is safe and feasible

According to researchers from Luton & Dunstable University Hospital NHS FT, Luton, UK, laparoscopic Roux-e-Y gastric bypass (LRYGB) and concomitant laparoscopic abdominal wall hernia repair (LAWHR) using a prosthetic mesh is safe and feasible. The study was presented at this year’s Annual Scientific Meeting of the British Obesity and Metabolic Surgery Society in Leamington Spa, UK, from 22–24 January.

LSG does not relieve or resolve GERD

Laparoscopic sleeve gastrectomy does not resolve or relieve gastroesophageal reflux disease (GERD) and in some instances may actually contribute to reflux, according to the study by researchers from the Madigan Army Medical Center, Ft Lewis, WA.

"Bariatric surgery isn't one-operation-fits-all. It really needs to be tailored to the patient," said study author, Dr Matthew Martin. "Somebody who has significant reflux symptoms, or GERD, a sleeve may not be the best option for them, and it's certainly something that needs to be discussed before surgery.”

Sleeve has fewer complications than bypass

The early results from the Swiss Multicentre Bypass or Sleeve Study (SM-BOSS) have shown that laparoscopic sleeve gastrectomy was associated with shorter operation time and a trend toward fewer complications than with laparoscopic Roux-en-Y gastric bypass (LRYGB), however, the difference was not statistically significant.

More time to recuperate the costs of bariatric surgery

The time taken to recuperate the costs from bariatric surgery are more likely to be double the 5.25 years previously estimated for laparoscopic adjustable gastric band (LAGB), according to a study that assessed The Business Case for Bariatric Surgery Revisited: A Non-Randomized Case-Control Study business case for bariatric surgery published online in the journal PlosOne.

Study: Bypass has less overall failure rates than band

Laparoscopic adjustable gastric banding has similar rates of procedure-related reoperation and significantly higher rates of weight loss failure compared to bypass, according to a study from researchers at Virginia Commonwealth University Medical Center, Richmond, VA.

Banded bypass reduces long-term weight regain

It is clear by now that after five years the standard Roux en Y bypass is faced with a considerable amount of re-operations due to weight regain. This can result in up to 30 to even 50% of the initial patients requiring revisional surgery. The main reason for the weight regain is the dilatation of the gastric pouch, eventually accompanied by dilatation of the anastomosis and/or small bowel.
