The Conversion Time of Cysts to Inactive form After Percutaneous Treatment of Hepatic Hydatid Disease and Predisposing Factors in This Process

Aim: This study aimed to evaluate the duration of cyst inactivation after percutaneous treatment of hepatic hydatid disease and the factors that may affect this process. Methods: Ultrasound follow-up records were evaluated, and the criteria for cyst inactivation were determined. Cyst type, cyst size, and location were listed after scanning pre-treatment ultrasound reports. Percutaneous treatment technique, aspirated cyst content, complications, and duration of catheterization were listed. The time elapsed from percutaneous treatment to cyst inactivation was defined as inactivation time. Ultrasound follow-up period, cyst size at the last follow-up, and inactivation time were recorded. Results: A total of 116 patients were included in the study. The mean follow-up period after treatment was 1003.95 +/- 293.23 days. The mean inactivation time was 420.99 +/- 221.18 days. The size of the inactivated cysts decreased significantly compared to the pre-treatment cyst size (p=0.001). There was a positive correlation between cyst size and duration of catheterization (p=0.0001). The inactivation time decreased with increased duration of catheterization (p=0.001). There was a significant decrease in the inactivation time in patients who presented with complications (p=0.008). Conclusion: Patients who develop complications after percutaneous treatment and patients with longer catheterization exhibit shorter cyst inactivation time.
