Genital tract burns during rollerball endometrial coagulation
Summary
Three women sustained thermal injuries during hysteroscopic rollerball endometrial ablation. Potential causes include device insulation failure, current diversion, and electrical leakage, highlighting safety concerns for this gynecological procedure.
Area of Science:
- Gynecological surgery
- Medical device safety
- Electrosurgery
Background:
- Hysteroscopic rollerball endometrial ablation is a common procedure for abnormal uterine bleeding.
- Electrosurgical devices carry inherent risks of thermal injury.
- Ensuring device integrity and proper electrical current management is crucial for patient safety.
Observation:
- Three cases of thermal injury were reported in women undergoing hysteroscopic rollerball endometrial ablation.
- The injuries occurred during or shortly after the procedure.
- Detailed analysis of the device and surgical events was performed.
Findings:
- Possible mechanisms for thermal injury include insulation failure of the rollerball electrode.
- Current division, where the resectoscope sheath acts as an unintended return electrode, was identified as a potential cause.
- Capacitative leakage of electrical current from the active electrode to the sheath was also implicated.
Implications:
- These findings underscore the importance of rigorous device inspection and maintenance to prevent insulation failures.
- Surgical technique and awareness of potential current pathways are critical to mitigate risks.
- Further investigation into device design and electrosurgical safety protocols may be warranted to enhance patient safety during endometrial ablation.
