Proposal of a new preliminary scoring tool for early identification of significant blunt bowel and mesenteric injuries in patients at risk after road traffic crashes

摘要

PurposeBlunt bowel and mesenteric injuries (BBMI) are regularly missed by abdominal computed tomography (CT) scans. The aim of this study was to develop a risk assessment tool for BBMI to help clinicians in decision-making for blunt trauma after road traffic crashes (RTCs).MethodsSingle-center retrospective study of trauma patients from January 2010 to April 2015. All patients admitted to our hospital after blunt trauma following RTCs and CT scan at admission were assessed.ResultsOf the 394 patients included, 78 (19.8%) required surgical exploration and 34 (43.6%) of these had a significant BBMI. A univariate and multivariate analysis were performed comparing patients with BBMI (n=34) and patients without BBMI (n=360). A score with a range from 0 to 13 was created. Scores from 8 to 9 were associated with 5-25% BBMI risk. The power of this new score8 to predict a surgically significant BBMI had a sensitivity of 96%, specificity of 86.4%, positive predictive value (PPV) of 48% and negative predictive value (NPV) of 99.4%.ConclusionThis score could be a valuable tool for the management of blunt trauma patients after RTA without a clear indication for laparotomy but at risk for BBMI. The outcome of this study suggests selective diagnostic laparoscopy for a score8 in obtunded patients and 10 in all other. To assess the value and accuracy of this new score, a prospective validation of these retrospective findings is due.
