ABSTRACTObjective:identify risk factors for mortality in patients who underwent laparotomy after blunt abdominal trauma.Methods:retrospective study, case-control, which were reviewed medical records of blunt trauma victims patients undergoing laparotomy, from March 2013 to January 2015, and compared the result of the deaths group with the group healed.Results:of 86 patients, 63% were healed, 36% died, and one patient was excluded from the study. Both groups had similar epidemiology and trauma mechanism, predominantly young adults males, automobilistic accident. Most cases that evolved to death had hemodynamic instability as laparotomy indication - 61% against 38% in the other group (p=0.02). The presence of solid organ injury was larger in the group of deaths - 80% versus 48% (p=0.001) and 61% of them had other associated abdominal injury compared to 25% in the other group (p=0.01). Of the patients who died 96% had other serious injuries associated (p=0.0003). Patients requiring damage control surgery had a higher mortality rate (p=0.0099). Only one of 18 patients with isolated hollow organ lesion evolved to death (p=0.0001). The mean injury score of TRISS of cured (91.70%) was significantly higher than that of deaths (46.3%) (p=0.002).Conclusion:the risk factors for mortality were hemodynamic instability as an indication for laparotomy, presence of solid organ injury, multiple intra-abdominal injuries, need for damage control surgery, serious injury association and low index of trauma score. RESUMOObjetivo:identificar fatores de risco para óbito em pacientes submetidos à laparotomia exploradora após trauma abdominal contuso.Métodos:estudo retrospectivo, caso-controle, no qual foram revisados prontuários dos pacientes vítimas de trauma contuso submetidos à laparotomia. Foram avaliados: variáveis epidemiológicas, mecanismo de trauma, lesões anatômicas das vísceras abdominais, lesões associadas, necessidade de operação para controle de danos reoperação e desfecho.Resultados:dos 86 pacientes, 63% foram curados, 36% foram a óbito e um paciente foi excluído do estudo. Ambos os grupos possuíam epidemiologia e mecanismo de trauma semelhantes, predominantemente adultos jovens do sexo masculino, vítimas de acidente automobilístico. A maioria dos casos que evoluíram a óbito teve instabilidade hemodinâmica como indicação de laparotomia - 61% contra 38% do outro grupo. A presença de lesão de víscera maciça foi maior no grupo óbitos - 80% vs. 48%, e 61% destes tinham o
