Traumatisme de la rate: facteurs prédictifs d'échec du traitement non-opératoire

INTRODUCTION: Non-operative management of blunt splenic injury in adults has been applied with increasing frequency. However, predictive criteria for successful non-operative management are still a matter of debate. METHODS: we retrospectively reviewed all cases of blunt splenic injury in adult patients from 1997 to 2006. RESULTS: Of 190 patients with blunt splenic trauma (median age: 33 years, range 16-98), 43.7% (n=83) underwent emergency surgical intervention (Group I), and 56.3% (n=105) of patients were admitted for conservative treatment of splenic trauma. Conservative treatment was successful in 76.6% (n=82) (Group II), while 23.4% (n=25) of patients required a laparotomy (Group III). Ultimately, 43.2% of patients were successfully managed non-operatively, and 56.9% underwent laparotomy. Mechanism of injury was not significantly different among three groups. Group I patients presented significantly more frequently with hypovolemic shock (p<0.01), associated injuries (p<0.01), and high grade of splenic injury (p<0.01). All patients with active bleeding as evidenced by extravasation on CT scan, underwent exploratory laparotomy. Failure of non-operative management increased significantly with splenic trauma grade (grade I (0%), grade II (22.6%), grade III (27.6%) and grade IV (40%), (p
