RT Journal Article SR Electronic T1 Endoscopic transmission of hepatitis B virus. JF Gut JO Gut FD BMJ Publishing Group Ltd and British Society of Gastroenterology SP 171 OP 174 DO 10.1136/gut.24.2.171 VO 24 IS 2 A1 G G Birnie A1 E M Quigley A1 G B Clements A1 E A Follet A1 G Watkinson YR 1983 UL http://gut.bmj.com/content/24/2/171.abstract AB Although transmission of hepatitis B virus (HBV) infection has long been recognised as a potential hazard of gastrointestinal endoscopy, there has been little evidence of direct patient-to-patient cross-infection after such procedures. We wish to report a case of type B viral hepatitis almost certainly acquired at endoscopy from an instrument sterilised in the conventional manner, but which had been used on the previous day on a patient with bleeding oesophageal varices who was incubating type B viral hepatitis.
