Colorectal perforation with barium enema in the elderly: case analysis with the POSSUM scoring system.

Colorectal perforation is a serious complication of barium-enema examination, as the resultant contamination of the intraperitoneal or extraperitoneal space may result in a severe septic course. Between 1 October 1993 and 30 September 1996, four patients had colorectal injuries after barium-enema examinations at the Far Eastern Memorial Hospital, Taipei, Taiwan. Their mean age was 80 years and three of them died, despite the implementation of early and aggressive treatment. To examine the differences between this high crude mortality rate and reports of zero mortality, we retrospectively analyzed the data with the well established predictive surgical scoring system, the Physiological and Operative Severity Score for the enUmeration of Morbidity and mortality (POSSUM), to estimate the potential risk of death in these four patients.
