우리들 병원 안용 원장님의 SPINE저널에 게재된 논문 입니다.
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.
