Abstract

Background

The different bariatric surgery techniques that alter the digestive anatomy also modify the gastric absorption surface. Since alcohol is a substance that is mainly metabolized in the stomach, the goal of this study was to determine alcohol absorption before and after a laparoscopic sleeve gastrectomy (LSG) in the same patients.

Methods

Studies were carried out on 12 morbidly obese patients who underwent a LSG (eight men and four women). Each patient was given 3.6 ml of red wine to drink at 14% for each liter of body water mass. Alcotest values (Alcoscan Alcomate AL-6000) were measured 10 min after the wine dose had been consumed. Measurements were then repeated every 5 min until the alcohol had been completely eliminated from the bloodstream. During the postoperatory period (median of 2.3 months), the measurement was repeated with the total dose per kg adjusted to the new water body mass. The results were measured with a nonparametric analysis for repeated samples.

Results

The maximum average peak of the Alcotest was 2.02 g/l during the postoperative period compared to 0.87 g/l during the preoperative period (p = 0.001 Wilcoxon). At 175 min, the blood alcohol level value reaches zero (0) in all pre-operatory patients, while after surgery, an average value of 0.26 g/l was observed (p = 0.027 Wilcoxon). After 4 h, an Alcotest average of 0.20 g/l was observed in these patients.

Conclusion

Alcohol absorption was considerably modified after LSG with higher and longer blood alcohol values for equivalent amounts of alcohol.
