내시경 수술을 시행하는 의사와 스텝들에게 방사선 피폭은 매우 민감한 사항 입니다. 이 논문에서는 경피적 내시경 요추 절제술을 시행하는 동안의 방사선 피폭량을 분석하고 일년에 허용 가능한 수술 건수를 산정했습니다.

STUDY DESIGN

A prospective study.

OBJECTIVE

-To determine the radiation dose to which the surgeons are exposed during percutaneous endoscopic lumbar discectomy (PELD)

-To calculate the allowable number of cases per year.

SUMMARY OF BACKGROUND DATA

-Minimal invasiveness can be achieved through the use of fluoroscopy and endoscopy.

-The radiation dose to the surgeon during PELD is unknown.

METHODS

-The occupational radiation dose absorbed by 3 spinal surgeons performing 30 consecutive PELDs (33 levels) during a 3-month period was evaluated.

-Transforaminal PELDs were performed according to the standard technique.

-Part of measured the radiation exposure: neck, chest, arm, and both hands of the surgeons

-Occupational exposure guidelines of National Council on Radiation Protection & Measurements were used to calculate the allowable number of procedures per year.

RESULTS

-mean operation time: 49.8 minutes / mean fluoroscopy time was 2.5 minutes.

(No significant correlations)

▶Calculated radiation doses per operated level

-neck: 0.0785 mSv /chest: 0.1718 mSv /right upper arm: 0.0461 mSv/ left ring finger: 0.7318 mSv/ right ring finger: 0.6694 mSv.

▶allowable number of cases per year

-using a lead apron: 5379 operations can be performed per year

-without using a lead apron: 291 operations can be performed

CONCLUSION

-Without radiation shielding, a surgeon performing 291 PELDs annually would be exposed to the maximum allowable radiation dose.

-Given the measurable lifetime radiation hazards to the surgeon, the use of adequate protective equipment is essential to reducing exposure during PELD.
