Pregnancy Outcome of Patients Following Bariatric Surgery As Compared with Obese Women: A Population-base Study


In five studies, Type 2 diabetes improved in 42 of 68 (61.8%) patients after LAGB and 66 of 80 (82.5%) after laparoscopic sleeve gastrectomy (LSG). Women who become pregnant after bariatric surgery have a lower risk for gestational diabetes mellitus and fetal macrosomia, but are more likely to be anemic, according to a retrospective study published in the June 18 edition of the Journal of Maternal-fetal & Neonatal Medicine. The study compared the outcomes of 326 pregnant women who had one pregnancy before and after bariatric surgery, and 1,612 women with obesity who had at least two consecutive deliveries.


Long-term Follow-up Evaluation of Revisional Gastric Bypass After Failed Adjustable Gastric Banding


A new study in Surgical Endoscopy (June 27) about revision from gastric band to gastric bypass found the early postoperative morbidity rate was 10.2 percent and patients went from 37.9 kg/m2 before gastric bypass to 28.8 kg/m2 5 years after gastric bypass. The study authors, from Innsbruck Medical University in Austria, call this study the "first report on the long-term outcome after conversion of failed adjustable gastric banding to gastric bypass." The median interval between gastric banding and gastric bypass was 6.6 years. The study reports on 108 patients with a median follow-up period of 3.4 years.


Bariatric-related Medical Malpractice Experience: Survey Results Among
ASMBS Members


According to an article in press in SOARD, the number of years in practice (OR 1.03; P = .03) and greater career volume (OR 8.5; P = .01) were independently associated with an increased likelihood of having a bariatric-related medical malpractice claim at some point in a bariatric surgeon's career. The findings are consistent with data reported by others in the overall field of surgical practice. Study authors point out that malpractice claims are more often made against the most experienced surgeons and that most general surgeons will have experienced at least one malpractice claim or indemnity payment over their lifetime. All U.S.-based members of the ASMBS were asked to complete a survey regarding their bariatric-related medical malpractice experience. Of the 1,672 eligible members that received the survey, 330 responded (19.7%). Mean years in practice was 15.3±9. Forty-eight percent of respondents did not report a bariatric-related lawsuit filed against them. Of the 464 lawsuits reported by 156 surgeons, 126 were settled out of court (27%), 249 were dropped (54%), and 54 (18%) went to trial. Seventy-two percent of cases that went to trial were found to be in favor of the defense.


Comparison Between Laparoscopic Sleeve Gastrectomy and Laparoscopic Adjustable Gastric Banding for Morbid Obesity: A Meta-analysis


A meta-analysis (11 studies involving 1,004 patients), published in the July edition of Obesity Surgery, found LSG achieved greater excess weight loss (EWL) than laparoscopic adjustable gastric banding (LAGB) (37.8% vs. 33.9%) after 12 months. In five studies, Type 2 diabetes improved in 42 of 68 (61.8%) patients after LAGB and 66 of 80 (82.5%) after LSG.
