Liver biopsies are one of the most performed procedures in KFSH&RC, which is known to be one of the largest oncology and transplant centers in the middle east. Image guiding biopsies have proven to be cost effective and of minimal complicationsWe reviewed the procedural aspects, specimen adequacy, diagnostic accuracy and complications and of imaging guided liver biopsies done in the Interventional Radiology Section at KFSH&RC over an 11-month period.
We retrospective stratifide the cases based on age group, gender, native vs. transplant liver, focal vs non-focal lesion, pre-biopsy laboratory assessment, indication of the biopsy, underlying disease (if any) and pathological findings. Type of biopsy, number of passes, adequacy of the specimen and post procedural complications were all assessed in our study.
The pediatric population represented 24.6%(42) while adults were 74.4% (124) of the cases done. Female patients represented 41.5% (69) while male patients represented 58.5 % (97) of the biopsies.32% (53) specimens were obtained from a diffuse transplant while 1.8% (1) were obtained from the patients with focal transplant lesions.
As per native liver subjects, 46.5% (52) from a focal lesionwhile (60) 53.5 % were obtained from a diffuse pathology.
The sample was adequate in 97% (161) of the cases. The biopsytract was plugged in 1.2% (2) of the cases. No immediate post procedural complications.
The study shows that adherence to hospital guidelines has proven to decrease the complication rates and increase the accuracy and specimen adequacy of liver biopsies.
