Computed tomography (CT) scans frequently show abnormalities after percutaneous biliary procedures (PBPs), with nearly half of patients exhibiting findings. Many of these CT scan abnormalities are asymptomatic, highlighting their common occurrence post-procedure.

Area of Science:

  • Radiology
  • Gastroenterology
  • Interventional Radiology

Background:

  • Percutaneous biliary procedures (PBPs) are common interventions.
  • Assessing post-procedural complications requires accurate imaging interpretation.

Purpose of the Study:

  • To determine the frequency, type, and extent of CT-depicted abnormalities after PBPs.
  • To correlate CT findings with clinical presentation and procedural difficulty.

Main Methods:

  • Prospective study of 31 consecutive PBPs in 29 patients.
  • Abdominal CT scans performed 24-72 hours post-procedure.
  • Analysis of CT findings and correlation with clinical data.

Main Results:

  • 15 abnormalities in 14 patients (45%) were identified on CT.

  • Abnormalities included hematomas, fluid collections, free air, and contrast collections.
  • Only 5 patients with positive CT findings had clinically apparent complications.
  • Positive CT findings were associated with more needle passes and difficult procedures.

    • Conclusions:

    • CT scan abnormalities are common after PBPs.
    • Many CT findings are incidental and not clinically significant.
    • CT is valuable for detecting post-PBP abnormalities, even in asymptomatic patients.
