Hepatic periportal tracking (PPT) on initial CT scans does not indicate the need for surgery in blunt hepatic trauma patients. Routine follow-up CT scans are unnecessary and do not impact patient management or outcomes.

Area of Science:

  • Trauma Surgery
  • Diagnostic Imaging
  • Hepatobiliary Medicine

Background:

  • Nonoperative management is common for hemodynamically stable blunt hepatic injuries.
  • Hepatic periportal tracking (PPT) on initial CT scans has been proposed as a marker for significant injury, potentially contraindicating nonoperative management.
  • The role of follow-up CT scans in managing blunt hepatic trauma remains unclear.

Purpose of the Study:

  • To evaluate the clinical significance of hepatic periportal tracking (PPT) on initial computed tomographic (CT) scans in patients with blunt hepatic trauma.
  • To determine the utility and impact of routine follow-up CT scans in the nonoperative management of blunt hepatic injuries.

Main Methods:

  • Retrospective chart review of 58 hemodynamically stable patients with blunt hepatic trauma at a regional trauma center.

  • Initial CT scans were reviewed for the presence of PPT.
  • Data collected included age, Injury Severity Score (ISS), operative intervention, complications, and the timing and radiographic appearance of follow-up CT scans.

    • Main Results:

    • Twenty-nine percent of patients showed radiographic evidence of PPT; 71% did not.
    • No statistically significant differences were observed in age, ISS, injury grade, nonoperative management success rates, or complication incidence between groups.
    • Routine follow-up CT scans did not alter patient management in any case.

    Conclusions:

    • The presence of PPT on initial CT scans is not clinically significant and does not preclude nonoperative management of blunt hepatic injury.
    • Routine follow-up CT scans are not indicated for blunt hepatic trauma patients and should be obtained based on clinical status.
    • Adopting these findings could lead to significant healthcare cost savings without compromising patient care.
