Acute pancreatitis in identical twins.

Identical twins, 34-years-old at the time, developed abdominal pain of similar character while at a holiday resort. Both had drunk a greater amount of alcohol than usual, approximately eight 200-mL glasses of beer. The symptoms in one twin forced him to present to hospital where his plasma amylase level was found to be 2300 u/L. The other had the same symptoms, but did not present to hospital; however, when the symptoms later recurred, he also was found to have pancreatitis. Acute pancreatitis occurring simultaneously in identical twins has been reported only on one previous occasion.
