Abstract
When a suspicious spine lesion is identified, an accurate diagnosis based on tissue biopsy is needed to direct towards the correct treatment protocol. Several studies concluded that the percutaneous fluoroscopy guided biopsy of vertebral lesions is a safe, effective and accurate diagnostic tool and is preferred over open techniques when possible. The aim of this study was to review percutaneous fluoroscopy guided transpedicular spinal biopsies at a tertiary hospital over a 6-year period.
The research design was a retrospective review of patients who underwent percutaneous transpedicular spinal biopsies under fluoroscopy guidance at a tertiary hospital over a six year period (1st January 2016 to the 31st December 2021).
The spine theatre registry and hospital records system were used as the source for data collection. Statistical analysis was conducted to determine the effectiveness of transpedicular spinal biopsies, compare spinal pathology amongst age and gender and to identify any complications.
The study analysed 180 biopsies, 120 yielding a positive result (66.67%). Of these 8.9% were pyogenic infection, 18.4% neoplasm, 36.7% Tuberculosis and 2.7% other. There were 75 males and 105 females with an age range between 9 and 86 years and mean age of 43.44. Comparing age and gender found no statistical significance (p = 0.778). Comparing biopsy result and gender showed no statistical significant relationship (p = 0.970). Comparison of biopsy result with age showed no statistical significant association (p = 0,545). Four complications were identified (2.22%).
The study showed that fluoroscopy guided percutaneous transpedicular biopsy is an effective and safe modality in obtaining spinal specimens in all age groups for a wide spectrum of spinal pathological lesions.
