    Journal: Rev Assoc Med Bras (1992); 1995; 41(1):53-9. PubMed ID: 7550416.
    Abstract:
    Injury of the extra-hepatic biliary tract is infrequent, occurring in approximately 3.5% of all patients with blunt and penetrating abdominal trauma. The incidence of this injury caused by blunt abdominal trauma is rare. PURPOSE--Retrospective analysis of 5069 patients with abdominal trauma treated at the Department of Surgery University of São Paulo School of Medicine over a six-year period from 1986 through 1991. METHODS--Forty five patients with gallbladder and extra-hepatic ducts injury were identified (0.89%) and divided in two groups according to the nature of trauma: 12 caused by non-penetrating injuries and 33 to penetrating injuries. Records, including operative and pathology reports, were reviewed to study the site of injury, associated intra-abdominal injuries, incidence, trauma scores, treatment, morbidity, mortality rates and correlated with the nature of the trauma. RESULTS--Overall mortality was 24.4%. The incidence was greater in patients sustaining penetrating abdominal trauma (p < 0.05). Forty of the 45 patients (88.9%) had liver lacerations, the most commonly seen injuries. The patients with blunt abdominal trauma had significant different trauma scores (p < 0.05) than those with penetrating trauma, indicating greater severity in this group of patients. CONCLUSION--There is a relation between severity of trauma and incidence of extra-hepatic biliary tract injury. However, in the penetrating trauma, the incidence of trauma is correlated with the direction of the wound and there is no relation with the severity of trauma. The greater mortality seen in the patients sustaining non-penetrating injury (p < 0.05) supports this observation.
