Background. The rates of obesity and substance abuse are high among US veterans. Objective. To examine weight loss and substance abuse rates following bariatric surgery in veterans with a history of substance abuse (SA). Methods. A prospective database of consecutive bariatric operations was reviewed. Data for SA patients were compared to patients without a substance abuse history (NA). Behavioral medicine staff followed patients throughout the pre- and postoperative courses. Results. Of 205 bariatric surgery patients, there were 74 (36.1%) SA patients. The mean preoperative body mass index (BMI) was 46.2 ± 8.1 kg/m(2), and percent excess weight loss at 12 months was 71.8%, 58.0%, and 33.5% for Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, and laparoscopic gastric banding, respectively, not significantly different than the NA group (P = 0.15, 0.75, 0.96). Postoperative substance abuse in SA and NA patients was 8.1% and 1.5%, respectively (P = 0.234). Conclusion. A prior history of substance abuse is common in veterans undergoing bariatric surgery; weight loss results are comparable to the general veteran bariatric cohort. Rates of substance abuse are low postoperatively, but higher in patients without a prior history of substance abuse. Close multidisciplinary followup throughout the postoperative course is likely to be integral to the patient's success.

    ABSTRACT: Emerging research suggests that some bariatric surgery patients are at a heightened risk for developing substance use problems, especially alcohol use problems. An exhaustive literature review was conducted in January 2015 to investigate all articles published that included data on postoperative alcohol use, alcohol use disorders, and illicit drug use among bariatric surgery patients. Twenty-three studies reported on alcohol and/or substance use among bariatric patients. Six studies longitudinally assessed alcohol use behaviors; 3 of these studies found an increase in alcohol use following surgery. Six studies were cross-sectional, and 2 studies assessed medical records. Five studies investigated the prevalence of admissions to substance abuse treatment, and 3 studies combined alcohol and drug use data in a single index. Six studies reported on illicit drug use and reported low-postoperative use. The studies' samples were primarily non-Hispanic white females in their upper 40s, and only 11 of the 23 studies utilized validated assessment instruments. Studies employing longitudinal designs and large sample sizes indicate that bariatric patients who had the gastric bypass procedure are at an elevated risk for alcohol use problems postoperatively. Research also indicates that bariatric surgery patients might be overrepresented in substance abuse treatment facilities. Risk factors for problematic postoperative alcohol use include regular or problematic alcohol use presurgery, male gender, younger age, tobacco use, and symptoms of attention deficient and hyperactivity disorder. As a whole, however, studies indicate bariatric surgery patients demonstrate a low prevalence of problematic alcohol use, and studies about gastric bypass patients are not entirely conclusive. Prospective, longitudinal studies are needed, utilizing standardized and validated alcohol assessment instruments that follow postoperative bariatric patients well beyond 2 years, and account for types of bariatric procedure. Finally, study samples with greater racial/ethnic diversity and wider age ranges are needed. Copyright © 2015 by the Research Society on Alcoholism.
