A prospective survey on all patients undergoing fibreoptic upper gastrointestinal endoscopy during a 3 month period was conducted to determine the risk of transmission of hepatitis B. Four hundred and sixty‐eight patients underwent 637 endoscopy examinations in 47 endoscopy sessions. Of these, 15% were positive for hepatitis B surface antigen (HBsAg), 58.9% anti‐HBs/anti‐HBc‐positive and 26.1% negative for hepatitis B virus (HBV) markers on entry into the study. One hundred and eleven patients with no HBV markers underwent endoscopy during the same sessions as 69 HBsAg‐positive patients. Forty of these patients were endoscoped subsequent to HBeAg‐positive patients on at least one occasion. None of the HBV‐negative patients seroconverted to HBsAg or anti‐HBs/anti‐HBc at the end of 6 months. It was demonstrated that with a standard cleaning procedure there was no evidence of endoscopic transmission of HBV infection even in an endemic area.
