Failure Risk Factor For Non-Operative Treatment of Splenic Trauma
Abstract Background: Splenic trauma is a common pattern for admission in blunt abdominal trauma. The objective of this study is to identify risk factors for failure of non-operative management (NOM) in splenic trauma.Methods: This is a retrospective monocentric analysis of a prospectively collected database. All patients admitted in the university hospital of Nice [Centre Hospitalier Universitaire (CHU) de Nice, France] for a splenic trauma from January 1st 2006 to January 6th 2018 were included. Primary outcome was the need for delayed splenectomy as an indicator of NOM failure.Results: Two-hundred-eighty patients were included in this study. Most splenic lesions were severe grades (grade 3 or higher). In total, 83 splenectomies were performed urgently, i.e. 29% of patients; 88 angio-embolizations, i.e., 31% of patients with a success rate greater than 80%; 14.7% of 136 patients who had no previous angio-embolization required secondary splenectomy; 19.7% of the 61 patients who had anterior angio-embolization required secondary splenectomy. Age was not found associated with a higher failure rate (44 years in successful embolization vs 37.5 years in NOM-failure group, p = 0.15). Higher drop in hemoglobin levels between admission and 6 hours after admission was detected in the embolization failure group (-1.44 g/dl) as compared with the successful group (-0.68 g/dl), which approached statistical significance (p = 0.064).Conclusions: Hemoglobin monitoring in the hours following the admission of a patient with splenic trauma might be an important factor during the medical supervision of hemodynamically stable patients. Early identification of patients at high risk of NOM failure by hemoglobin monitoring may prevent late splenectomy.Level of evidence: IV (retrospective study)
