Area of Science:

  • Hepatology
  • Interventional Radiology
  • Surgical Techniques

Background:

  • Percutaneous and open liver biopsies are standard diagnostic procedures.
  • These procedures carry risks, including significant morbidity and mortality, particularly in patients with uncorrectable coagulopathy or highly vascular liver tumors.

Purpose of the Study:

  • To describe and evaluate a novel technique for liver biopsy in high-risk patients.
  • To assess the safety and efficacy of using gelatin hemostatic plugs for biopsy tract management.

Main Methods:

  • A technique involving laparoscopy for lesion identification and gelatin hemostatic plug placement in the biopsy tract was employed.
  • Hemostasis was confirmed after percutaneous plugging of the biopsy site.

Main Results:

  • The technique was successfully applied to seven patients (six with hepatic coagulopathy, one with a highly vascular tumor).
  • No intraoperative or postoperative complications were observed.
  • Patients experienced minimal discomfort and rapid return to baseline activity.

Conclusions:

  • The described biopsy site plugging technique offers a safe alternative for liver biopsy in patients with uncorrectable coagulopathy.
  • This method is suitable for patients requiring biopsy before bleeding disorder correction.
