Blunt liver trauma at Sunnybrook Medical Centre.

Between 1 June 1976 and 30 June 1985 Sunnybrook Medical Centre Regional Trauma Unit admitted 2,016 patients of whom 220 (11%) sustained liver injury. Of these 220 patients, 211 (96%) sustained blunt liver trauma; 175 of 176 patients who underwent open peritoneal lavage had a true positive lavage. Resuscitation was successful in 212 patients, of whom 209 underwent laparotomy and three were treated nonoperatively: 129 of 209 patients (62%) required only minor surgical treatment; the remaining 80 patients (38%) required major surgical procedures. The overall mortality was 29% (64/220). Eight patients died during resuscitation, one of them of liver hemorrhage. Of the 56 patients who died after admission, the cause of death was head injury in 31, liver hemorrhage in 11 (five intraoperatively) and 14 died of other causes. Overall, liver hemorrhage was the cause of death in 12 of 64 deaths (19%). In other words, 12 of the total of 220 patients (6%) died from liver-related mortality.

Abdominopelvic computerized tomography and open peritoneal lavage in patients with blunt abdominal trauma: a prospective study.

This prospective trial compares abdominopelvic computerized tomography and open peritoneal lavage in the diagnosis of blunt abdominal trauma. Fifteen patients (group 1) were evaluated by both methods. Another 15 patients (group 2) had only computerized tomography. Criteria for a "positive" scan were hemoperitoneum and evidence of solid organ injury. Criteria for "positive" lavage were a grossly bloody return, erythrocyte count greater than 20.0 X 10(9)/L and leukocyte count greater than 0.5 X 10(9)/L. At laparotomy, only injuries requiring repair or excision were considered "true positive". Patients who did not have laparotomy and had an uncomplicated clinical course were considered "true negative". With tomographic criteria alone for diagnosis there would have been one false-positive and three false-negative results, compared with three false positive and no false negatives for open peritoneal lavage alone. None of the three patients who had negative findings on laparotomy suffered any morbidity or died. Results of computerized tomography and open peritoneal lavage agreed in 8 of 15 patients (kappa value = 0.52), indicating a low level of agreement between the two. The authors believe that open peritoneal lavage remains the diagnostic procedure of choice in blunt abdominal trauma.
