title: Normal alcohol metabolism after gastric banding and sleeve gastrectomy: a case-cross-over trial.
abstract: BACKGROUND
  Severe obesity remains the leading public health concern of the industrialized world, with bariatric surgery as the only current effective enduring treatment. In addition to gastric bypass, gastric banding and sleeve gastrectomy have emerged as viable treatment options for the severely obese. Occasionally, poor postoperative psychological adjustment has been reported. It has been previously demonstrated that breath alcohol content (BAC) levels and time to sober were increased in postoperative gastric bypass patients. The aim of this study was to examine whether alcohol metabolism in patients undergoing restrictive-type bariatric procedures is also altered.
  
  
  METHODS
  Nine patients undergoing laparoscopic adjustable gastric banding (LAGB) and 7 patients undergoing laparoscopic sleeve gastrectomy (LSG) were recruited. Preoperatively, 3-month and 6-month BAC and time to sober were measured after administration of 5 ounces of red wine. In addition, participants were asked to complete a questionnaire of drinking habits.
  
  
  RESULTS
  The 16 total participants achieved a mean 44.7% 6-month excess weight loss. There were no significant changes in peak BAC or time to sober from preoperative levels (0.033%, 67.8 min, respectively) to 3 months (0.032%, 77.1 min, respectively, p = 0.421) or 6 months (0.035%, 81.2 min, respectively, p = 0.198).
  
  
  CONCLUSIONS
  Patients undergoing LAGB and LSG do not share the same altered alcohol metabolism as seen in gastric bypass patients. However, all bariatric surgery patients should be counseled regarding alcohol use.
