Metabolic syndrome is related to nonalcoholic steatohepatitis in severely obese subjects.

Background: Metabolic syndrome (MetS) and nonalcoholic fatty liver disease (NAFLD), ranging from simple steatosis to steatohepatitis (NASH), have become important health issues in obese subjects. In this study, we investigated the relationship between MetS and NASH in severely obese subjects.

Methods: A total of 111 non-alcoholic obese patients who underwent laparoscopic bariatric surgery (BMI 45.

Diagnostic value of ultrasonographic examination for nonalcoholic steatohepatitis in morbidly obese patients undergoing laparoscopic bariatric surgery.

Background: There are few data relating to the role of fatty score (FS) and modified fatty score (MFS) in ultrasonographic (US) examination on the diagnosis of nonalcoholic steatohepatitis (NASH) in patients undergoing bariatric surgery.

Methods: We investigated consecutive patients undergoing laparoscopic bariatric surgery with biopsy-proven nonalcoholic fatty liver disease. Patients with other liver diseases and significant alcohol consumption were excluded.

Hepatic histopathology of morbid obesity: concurrence of other forms of chronic liver disease.

Background: Obesity is a chronic inflammatory condition, with related steatohepatitis and liver fibrosis. The authors analyzed the hepatic histopathology in morbidly obese patients and predictors of concurrence of clinical and/ or histopathologic findings of steatohepatitis with other forms of chronic liver disease.

Methods: The histopathologic findings in the liver of 160 patients who were undergoing laparoscopic gastric bypass or gastric banding for morbid obesity, were examined.

The influence of Helicobacter pylori infection and corpus gastritis on the postoperative outcomes of laparoscopic vertical banded gastroplasty.

Background: Helicobacter pylori (HP) infection is linked to weight control through gastric inflammation-induced deregulation of satiety-related hormone, and eradication of HP before a weight reduction operation has been advocated. We aimed to examine the impact of HP infection and corpus gastritis on preoperative patient characteristics, postoperative complications and weight loss following laparoscopic vertical banded gastroplasty (LVBG).

Methods: A prospective cohort of 152 patients undergoing LVBG was enrolled.

A case-control study of association of Helicobacter pylori infection with morbid obesity in Taiwan.

Background: Obesity is an increasing health problem in developed countries, where the prevalence of Helicobacter pylori infection is decreasing. Recent studies suggested colonization of the stomach by H pylori might affect gastric expression of appetite- and satiety-related hormone and patients cured of H pylori infection gained weight. It was hypothesized that H pylori could be a contributing pathogenic factor in childhood and adult obesity.
