The Increasing Incidence of Adolescent Bariatric Surgery


A study published in the Journal of Pediatric Surgery (December), found bariatric surgery resulted in low complication rates among adolescents with severe obesity. Researchers reviewed 1,615 inpatient admissions using the Kids’ Inpatient Database (KID) to determine the length of stay and complication rates for bariatric surgeries in 2009. The procedures included 90 open gastric bypasses (2.44 days, 3.3% complication rate), 906 laparoscopic gastric bypasses (2.20 days, 3.5%), 150 sleeve gastrectomies (2.33 days, 0.7%), 18 laparoscopic gastroplasties (1.10 days, 0.0%) and 445 laparoscopic gastric bandings (1.02 days, 0.2%).


Bariatric Surgery May Improve Employment Status in Unemployed, Underserved, Severely Obese Patients


Employment status may improve after bariatric surgery in the unemployed population that suffers from morbid obesity. A retrospective review published in Obesity Surgery (December 5) compared the employment outcomes of unemployed patients with severe obesity (121 people) with those who had bariatric surgery (72 patients). At least one year post surgery, 24 percent of patients who had surgery had obtained full-time employment, compared to 9 percent of the non-surgical patients. Researchers noted future investigations are needed to get a more complete picture of surgery’s impact on employment.


Bariatric Surgery Benefits in Type 2 Diabetes Linked to Disease Duration


The Swedish Obese Subjects (SOS) study found bariatric surgery is more effective in treating type 2 diabetes in patients who have had the disease for a shorter period of time before surgery. Researchers found newly diagnosed patients maintained significantly higher remission rates at two, 10 and 15 years’ follow-up (roughly 94%, 60%, and 47%, respectively) than did those who had had diabetes for more than three years at baseline (about 39%, 12%, and 9%). The data was presented at the International Diabetes Federation World Congress.


Single-incision Laparoscopic Bariatric Surgery. A Systematic Review


A study published in SOARD (December 6), found single-incision laparoscopic bariatric surgery (SILBS) is safe and may be used in select patients. Researchers reviewed 14 randomized clinical trials and observational studies comparing the procedure to conventional laparoscopic bariatric surgery (CLBS). The overall morbidity rate was 5 percent in the SILBS group and 4.8 percent in the CLBS. The researchers noted SILBS may not be an appropriate procedure for patients with severe obesity, those who had previous abdominal surgery and patients who have an incisional hernia or a xiphoid umbilicus distance longer than 20 cm. Researchers concluded there was insufficient evidence to recommend its widespread use compared to conventional approach.


Review of Long-term Weight Loss Results After Laparoscopic Sleeve Gastrectomy


A review of 16 studies examining long-term weight loss after laparoscopic sleeve gastrectomy found the surgery shows “well-documented” weight loss outcomes after the procedure at five or more years, compared to short- and mid-term weight loss results. The overall mean percentage of excess weight loss remains greater than 50 percent (59.3%) at five years or more after surgery. The results of the study were published online on November 25 in SOARD.


Gastric Banding Benefited Overweight, Not Just Obese in Type 2 Diabetes


Results from a randomized controlled clinical trial that were presented at International Diabetes Federation meeting showed gastric banding can achieve significant weight loss and remission of diabetes in patients with type 2 diabetes who are overweight, suggesting that a lower body mass index threshold could be considered for the procedure. Type 2 diabetes patients with a BMI of 25-30 kg/m2 who received a gastric band achieved significantly greater weight loss (11 kg vs. 1 kg) and significantly higher rates of diabetes remission (52% vs. 8%) than did those who were treated with standard medical care, at two years. The 51-patient study was conducted by The Centre for Obesity Research and Education, which received educational funding from Allergan.
