Aims and objectives
Review diagnostic accuracy and patient feedback outcomes of our ultrasound-guided muscle biopsy service that is utilised for the investigation of myopathy.
Methods and materials
In selected difficult cases where open surgical biopsy was negative in patients with undiagnosed myopathy, a modified Bergström needle and suction technique was performed under ultrasound guidance to better target a viable muscle sample, identified through pre-procedural MRI.
Each of these cases were collected retrospectively over a one-year period. and the histology report was reviewed to confirm if this technique allowed adequate diagnosis.
In addition, each patient undergoing the procedure was retrospectively surveyed and asked to comment on any scar, complication and if they would favour the procedure in the future.
Results
A cohort of 8 patients underwent ultrasound-guided muscle biopsy using a modified Bergström needle and suction technique.
All samples were of diagnostic quality.
Patient feedback from the procedure was encouraging and no significant complications were reported.
Conclusion
Ultrasound-guided muscle biopsy using a modified Bergström needle is a suitable method for obtaining viable muscle tissue in the investigation of myopathy and is well-tolerated by patients.
