Abstract

Purpose

To evaluate a pumping emulsification device that can improve the physiochemical properties and stability of lipiodol emulsion for conventional transarterial chemoembolization.

Materials and methods

A pumping emulsification device constructed of a glass membrane with a hydrophobic surface with pore size of 50 μm in diameter was placed between two syringe adaptors. Epirubicin solutions were mixed with lipiodol with pumping exchanges using the emulsification device or a three-way cock. The ratios of epirubicin solution to lipiodol were 1:2 or 1:1. A total of 120 emulsions were created.

Results

The emulsification device showed significantly higher percentages of water-in-oil when compared with the three-way cock (97.9 % vs. 68.9 % in 1:2 ratio, and 82.1 % vs. 17.8 % in 1:1 ratio, p < .001). Droplet sizes in the emulsification device were more homogenous. Mean droplet sizes and viscosities in the emulsification device did not show any significant changes for 30 min after pumping, whereas in the three-way cock, the droplet sizes significantly enlarged and viscosities significantly decreased (p=.023 and p=.002).

Conclusion

The emulsification device can form a high percentage of water-in-oil emulsion with stable droplets sizes and viscosities. This developed device is promising to increase therapeutic effects in conventional transarterial chemoembolization.

Key points

• We developed new device for transarterial chemoembolization for liver cancer.

• The device can improve the physiochemical properties of lipiodol emulsion.

• The device can increase the therapeutic effects in conventional transarterial chemoembolization.
