Halothane hepatitis after jejunoileal bypass.

A case of halothane hepatitis occurring 14 months after jejunoileal bypass for morbid obesity in a 49-year-old woman is described. Hepatic dysfunction after bypass procedures is especially seen in the weight losing phase, and has been ascribed to protein malnutrition. Halothane is considered immunogenic and it is possible that the hepatitis was provoked by repeated halothane administrations due to the patient's altered immunological competence.
