Purpose
To compare our center's transition and outcomes from conventional CT (CT) to cone beam CT (CBCT) guidance for percutaneous placement of abscess drains.
Materials & Methods
Retrospective chart review of all abscess drain insertions performed using CT or CBCT guidance from 2005 to 2016. Abscess diameter, distance from skin, angle of approach, procedure lengths and costs, as well as complication rates were compared.
Results
A total of 213 procedures in 194 patients were performed in this study. There were no significant differences in patient characteristics, abscess diameter, distance from skin, or angle of approach between the two groups. Procedure length was significantly decreased in the CBCT group (37.4 min ± 20.1) when compared to the CT group (54.5 min ± 21.6) (p < 0.001). Material costs were the same in both treatment groups, however the CBCT group showed a $85 (51.8%) decrease in staffing cost when compared to the CT guidance group. Since implementing CBCT guidance in our practice, we have observed a steady decline in the use of CT guidance for abscess drain insertions. In the most recent three years we observed an average of 2 CT guided cases and 28.6 CBCT guided cases. We observed no significant differences in complication rates between the two groups.
Conclusions
CBCT guidance was associated with a significant decrease in procedure time and cost per procedure. Our study demonstrates an almost complete transition in our practice from conventional CT guidance to CBCT without compromising patient safety.
