Hollow viscus injury due to blunt trauma. Epidemiology and outcome in a large urban area

INTRODUCTION: Hollows viscus injury (HVI) is a rare occurrence and represents a clinical challenge because of its subtle and nonspecific clinical findings. The specific aims of this study were to determine the overall frequency of HVI in blunt trauma patients occurring in large urban area, the relative frequency of various hollow organ injuries, and the outcomes of such injuries. MATERIALS AND METHODS: A retrospective trauma registry review was performed by analysing data from the University Hospital Sant' Andrea in Rome and data from the Emergency Surgery and Trauma Care Unit of S. Filippo Neri Hospital in Rome The clinical records of all blunt abdominal trauma observed between January 2006 and December 2014 were blind analysed. Variables considered for analysis were: sex, age, time/type of trauma, associated injuries, timing/characteristics of operative treatment, ISS, AIS, length of hospital stay, morbidity and mortality. RESULTS: Seventy-one, 7.5% of all abdominal trauma recorded, were coded having 89 HVI. The overall morbidity and mortality rates were 29.6% (n=21/71) and 19.7% (n=14/71) respectively. Multivariate analysis indicated that only WBC (p=0.007) was significant independent predictor of morbidity whereas preoperative transfusion (p=0.010) and ISS (p<0.001) were significant risk factors for mortality. DISCUSSION: HVI is rarely found in patients with blunt abdominal trauma and it can be fatal and life-threatening, particularly in patients for whom a pertinent diagnosis is delayed. CONCLUSION: It appears clearly that during an ER evaluation of a blunt abdominal trauma an HIV has nowadays always to be considered to reach a quick diagnosis and prompt surgical intervention.
