Retention balloon catheters and barium enemas: attitudes, current practice and relative safety in the UK.

Balloon catheters have been associated with increased morbidity and mortality leading some to believe they should be banned, yet others find them both useful and safe if used properly. Questionnaires were sent to all Consultant Radiologists in the UK to document current practice. Particular attention focused on whether eight safety aspects are considered during their use. In this entirely retrospective study complications with both balloon and standard tip catheters were recorded during the 3-year-period 1992 to 1994 to assess their relative safety. Twenty-two percent of UK Radiologists routinely used a rectal balloon. This was not associated with any increase in mortality, but extraperitoneal rectal perforation was increased by a factor of 2.5. The routine use of retention balloon catheters may not be justified.
