Prevalence and predictors of asymptomatic XXXX in @entity1 undergoing gastric bypass surgery.

@entity1 @entity82 @entity1560 @entity28 @entity6 @entity167 @entity409 @entity1561 @entity412
BACKGROUND: @entity1561 ( @entity1561 ) is a form of @entity409 that is increasingly recognized. There are limited data on the prevalence of @entity1561 and the role of risk factors for @entity1561 among the morbidly @entity28 . HYPOTHESIS: The prevalence of asymptomatic @entity1561 among morbidly @entity28 @entity1 undergoing gastric bypass surgery is high, and there are identifiable risk factors for @entity1561 . DESIGN: Prospective case study. SETTING: University hospital. @entity1 : Forty-eight consecutive @entity1 undergoing gastric bypass surgery who had a concurrent open liver biopsy. Exclusion criteria included current consumption of more than 2 @entity167 beverages monthly and known @entity82 . A hepatopathologist blinded to clinical data reviewed biopsy specimens. MAIN OUTCOME MEASURES: The presence of @entity1561 or severe @entity82 , preoperative body mass index (BMI) (calculated as weight in kilograms divided by the square of height in meters), fasting @entity412 level, and presence of @entity6 ( @entity6 ). RESULTS: @entity1 (mean +/- SD age, 42 +/- 10 years; 33 @entity1 ) had an initial mean BMI of 59.9 +/- 12. Thirty-one @entity1 (65%) had moderate to severe @entity1560 . Only 6 (12%) had advanced @entity82 . Sixteen (33%) had evidence of @entity1561 . There was no difference in mean age, sex, BMI, or fasting @entity412 level between @entity1 with and without @entity1561 or advanced @entity82 . The odds of @entity1561 were 128 times greater (95% confidence interval [CI], 5.2-3137.0) and the odds of severe @entity82 75 times greater (95% CI, 4.5-1247.0) in @entity1 with @entity6 than in those without @entity6 . Preoperative BMI was not independently associated with @entity1561 (odds ratio, 1.01; 95% CI, 0.9-1.1) or severe @entity82 (odds ratio, 0.9; 95% CI, 0.86-1.02) after adjustment for @entity6 . CONCLUSIONS: Moderate to severe @entity1560 and @entity1561 are common among individuals undergoing gastric bypass procedures. @entity6 but not BMI is associated with @entity1561 and advanced hepatic @entity82 in these @entity1 .
