Background: Recently the Organ Injury Scaling Committee of the American Association for the Surgery of Trauma developed a Rectal Injury Scaling System (RISS). Little data exist regarding its clinical utility.
Methods: We retrospectively reviewed 45 patients with rectal injuries to assess the impact of the RISS on patient management and outcome. We compared RISS grade I patients (group I, partial-thickness injury) with patients with grades 2, 3, and 4 injuries (group II, full-thickness injury).
Results: Group II underwent distal rectal washout and repair of the injury twice as often and had a significantly higher rate of diversion of the fecal stream. This was associated with a 3-fold increase in complications. The only complications in group I were in patients managed with diversion of the fecal stream and distal rectal washout.
Conclusions: Our data suggest that aggressive surgical management for RISS grade I injury may not be necessary. Implementation of therapy based on the RISS may improve outcomes of civilian rectal trauma.
