UNLABELLED: Oesophageal dilatation is the most widely used treatment option for the management of oesophageal strictures. Complications include bleeding, a slight increase in body temperature, thoracic or abdominal pain, oesophageal perforation, brain abscess and bacteraemia. We performed a prospective study to evaluate the frequency of post-dilatation bacteraemia in nine patients subjected to a total of 50 dilatations. Bacteraemia was detected in 36 cases (72%), In all but three cases, however, it was transient and not associated with fever or other clinical complications. The organisms most commonly responsible (64%) were alpha-haemolytic streptococci (Streptococcus viridans), probably originating as contaminants from the oropharynx and oesophagus and introduced into the bloodstream during dilatation. Despite the relatively low incidence of bacteraemia-related postdilatation complications, the potential severity of such complications argues for the use of antibiotic prophylaxis as a routine measure prior to oesophageal dilatation. CONCLUSION: Oesophageal dilatation is associated with a high incidence of bacteraemia. The organisms most commonly responsible were alpha-haemolytic streptococci. We recommend the use of antibiotic prophylaxis as a routine measure prior to oesophageal dilatation.
