Area of Science:

  • Interventional Radiology
  • Hepatobiliary Surgery
  • Oncology

Background:

  • Subcapsular hepatocellular carcinomas require artificial ascites for improved visualization and organ protection during treatment.
  • Current methods for artificial ascites creation include the Seldinger technique and the one-step method.
  • Optimizing artificial ascites procedures is crucial for patient management.

Purpose of the Study:

  • To compare the efficacy and efficiency of the one-step method versus the Seldinger technique for artificial ascites creation.
  • To determine if the one-step method offers a higher success rate and faster procedure time.
  • To evaluate the performance in treatment-experienced patients.

Main Methods:

  • A retrospective study of 246 hepatocellular carcinoma patients requiring artificial ascites.
  • Patients were divided into two groups: Seldinger technique (95 patients) and one-step method (151 patients).
  • Data collected included success rates, procedure times, and patient treatment history.

Main Results:

  • The one-step method achieved a significantly higher complete success rate (88.1%) compared to the Seldinger technique (76.8%) (P < 0.05).
  • The mean procedure time for the one-step method (145.79 ± 133.37 s) was significantly shorter than the Seldinger technique (238.68 ± 95.58 s) (P < 0.05).
  • The one-step method demonstrated particular advantages in treatment-experienced patients.

Conclusions:

  • The one-step method is superior to the Seldinger technique for artificial ascites creation.
  • This method offers improved success rates and reduced procedure times.
  • The one-step method is recommended, especially for patients with prior treatment experience.
