Background Bariatric surgery is the only effective and long- lasting treatment of morbidly obese patients. However, the safety and efficacy of bariatric surgery in patients with hepatitis B viral (HBV) infection is not clear. The aim of the present study is to investigate weather HBV infection influences clinic features and outcomes of bariatric surgery . Methods The preoperative seropositivity of HBV surface antigen (HBsAg) using radioimmunoassay was determined in 592 patients (481 female, 111 male: mean age 30.5 +/- 8.1 years ; mean body mass index [BMI] 43.1 +/- 6. 0) who had undergone bariatric surgery (209 banding and 383 gastric bypass ) for their morbid obesity in the past 5 years. All the clinical data were prospectively collected and stored. Results The overall seroprevalence of HbsAg was 18.8%. Morbidly obese patients positive for HBV infection were associated with older age and higher diastolic blood pressure, but not with sex, BMI, liver enzyme, blood lipid, and glucose levels. Although minigastric bypass (MGB) had a better weight reduction than gastric banding, there was no difference in weight reduction between patients who were positive and negative for HBV infection. The weight loss curves and resolution of obesity-related comorbidities were similar between the two groups except the postoperative aspartate transaminase (AST) and alanine transaminase (ALT) were significantly higher in patients who were positive for HBV infection. During follow-up, two patients developed fulminating hepatitis after MGB with one mortality. Conclusion Morbidly obese patients with the existence of HBV infection do not influence the outcome of bariatric surgery , but continuing monitor of the liver function is indicated.
