Initial results of ct-guided percutaneous bone biopsy using an arrow oncontrol bone access system at Cho Ray Hospital
Main Article Content
Abstract
SUMMARY
Background: Computed tomography (CT)-guided percutaneous bone biopsy has been widely performed at big hospitals in Vietnam, but these techniques were done by using bone biopsy handle needle. Procedural time was usually prolonged, pain level of patients increased, especially osteopetrosis lesion, risk of not receiving samples. Therefore,
the purpose of our study was to assess the initial effectiveness of CT-guided percutaneous bone biopsy using Arrow Oncontrol bone access system.
Materials and methods: All the patients were performed CT- guided percutaneous bone biopsy at Cho Ray hospital from February 2016 to June 2017, 58 patients using Arrow Oncontrol bone access system. The techniques include: local anesthesia, confirming accurate lesion by CT scan, inserting 11G needle and 13G coaxial needle with Arrow Oncontrol bone access system putting into lesion, checking again by CT scan, drilling to take core sample. The efficacy, safety, pain level and procedural time were evaluated by variants: technique success rate, accuracy of histopathology, pain level, procedural time and complications.
Results: 58 patients were performed with CT-guided percutaneous bone biopsy using drilling Arrow Oncontrol system. Technique success rate was 96.5%, diagnostic accuracy histopathology was 87.9%, the correlation was strong (r = 0.95) between histopathological diagnosis and discharge diagnosis, low pain score (mild pain) 82.7%, technical median time 11 minutes, there were no complications.
Conclusions: CT-guided percutaneous bone biopsy using Arrow Oncontrol drill-assisted system had high technique success rates, high diagnostic accuracy of histopathology, mild pain level, fast and safe procedure.
