Blunt abdominal trauma: evaluation of diagnostic options and surgical outcomes.

BACKGROUND In the present study, it is intended to outline the diagnostic tests and their influences on decisions of the surgeon about patients presented with blunt abdominal trauma. METHODS One hundred forty-four patients (98 males, 46 females; mean age 36; range 17 to 84 years) admitted to Gazi University School of Medicine due to blunt abdominal trauma (BAT) between May 2003-May 2005 were reviewed retrospectively. Age, gender, injury mechanism, Glasgow Coma Scale, revised trauma score, follow-up period, applied diagnostic procedures, and treatment methods were evaluated. RESULTS The underlying cause was traffic accident in 126 (87.5%) patients, fall from height in 14 (9.7%) patients, and blows in 4 (2.8%) patients. Isolated abdominal trauma was seen in 21 patients and multisystem trauma in 123 patients. The most frequent associated trauma was head injury (66.6%). Abdominal ultrasonography (USG) was applied in 139 (97%) of the patients, and abdominal computed tomography (CT) was performed in 73 (51%). Diagnostic peritoneal lavage (DPL) was applied in 41 (28%) patients, and 15 (37%) of them proved to be positive. While emergency laparotomy was applied in 19 (13.2%) of the patients, 21 hemodynamically stable patients were diagnosed to have free fluid through USG and CT and were followed-up. During the follow-up period, 2 patients were scheduled to be operated, and small intestine perforation was found in these patients. The overall mortality rate for all patients was 16%, and the postoperative mortality rate with respect to the operated patients was 14.3%. CONCLUSION If USG, CT, and DPL are applied in a complementary manner, a large number of patients with solid organ injuries secondary to blunt trauma can be managed nonoperatively. Thus, unnecessary laparotomies can be avoided and related morbidities and mortalities decreased.
