A Prior History of Substance Abuse in Veterans Undergoing Bariatric Surgery

[摘要] 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/m2, 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.
