Zusammenfassung:Abstract Background Surgically induced weight loss improves nonalcoholic fatty liver disease (NAFLD) in morbidly obese Caucasian patients. Similar data are lacking from India. Objective To compare the histologic features of NAFLD in morbidly obese Indian patients before and 6 months after bariatric surgery. Histologic changes were also separately assessed according to the type of bariatric intervention. Setting Teaching institution, India; private practice. Methods All patients undergoing bariatric surgery from July 2012 to July 2013 underwent a routine liver biopsy at the time of bariatric surgery. If the biopsy specimen indicated NAFLD, patients were asked to undergo a second biopsy after 6 months. Baseline anthropometry, clinical data, biochemistry, and pathology were recorded and repeated at follow-up. Results Eighty-eight of 134 index biopsy specimens indicated NAFLD. Thirty patients had paired liver biopsies. Steatosis was present in all, 14 had lobular inflammation, 10 had ballooning degeneration, and 14 had fibrosis. Mean time between the biopsies was 7.1 months (range 6–8 months). At the second biopsy, steatosis had resolution in 19 and improvement in 11, lobular inflammation had resolution in 12 and improvement in 2, ballooning had resolution in 9 and improvement in 1 and fibrosis had resolution in 11 and improvement in 3 ( P
