Infectious endocarditis after fiberoptic sigmoidoscopy. With a literature review

Infectious endocarditis is a feared complication of procedures causing bacteremia. Gastrointestinal procedures cause bacteremia, but are seldom followed by infectious endocarditis. Of nine cases found in the English literature, only five have convincing evidence that endocarditis resulted from the gastrointestinal procedure. I present a new case of endocarditis due to Streptococcus sanguis type II after fiberoptic sigmoidoscopy.
