The impact of ERCP X-ray machine radiation on healthcare workers: the radiation dose for treatment is three times higher than that for diagnosis


ERCP requires the use of x-ray equipment, which brings the problem of radiation can not be ignored, and may even make some health care workers shy away. ERCP radiation in the end how much, on the health care personnel’s body how much impact? The following section will discuss this issue.

First, let’s introduce two common terms for radiation dose: incident skin dose and effective dose. The former refers to the radiation dose absorbed by the skin or muscle including backscattered light, in Gy; the latter refers to the average radiation dose received by different organs or tissues, weighted by the biological effect of the organ or tissue and radiosensitivity, in Sv. As an example, the radiation dose of a chest X-ray is about 1.1mSv, the dose of a chest X-ray is 0.2mSv, the dose of an abdominal CT is 10mSv, and the dose of a 20-hour airplane ride is 0.1mSv. The dose from a 20-hour airplane ride is 0.1mSv, and the annual dose from smoking 20 cigarettes a day is 0.5-2mSv. The upper limit of the effective dose recommended by the International Commission on Radiological Protection (ICRP) for occupationally exposed persons is 20mSv/year. If the annual dose exceeds 20mSv, it is recommended that the dose not exceed 50mSv in any one year.

Studies have shown that the effective dose per operation for ERCP ranges from approximately 2-6 mSv. For lower bulbar fluoroscopes and when shielded plates are used, the endoscopist receives an effective dose of 2-90 μSv per operation. the effective dose to the ends of the extremities averages 30 μSv, and is as high as 350-800 μSv when upper bulbar fluoroscopes are used and shielded plates are not utilized. and assistants, because of the distance, are exposed to less radiation. When assessed in terms of incident skin dose, the amount per ERCP is 55-347 mGy, while therapeutic ERCPs are more than three times higher than diagnostic ones. The figure below shows data on radiation exposure to endoscopists obtained from two related publications.

Effects of ERCP radiation on healthcare professionals

According to the above results, as long as the protection is good, the exposure time is controlled, and the amount of radiation is not excessive, the radiation caused by ERCP does not seem to be as terrible as imagined. Of course, this is the average data, different centers, different equipment, different difficulty of surgery, different surgeon’s style will affect the data. In addition, the above sources are from foreign studies, and it is unknown whether differences in equipment and perceptions at home and abroad lead to different results.

A well-performing and functional X-ray machine has a significant role in reducing ERCP radiation.

PLX7100A is the interventional surgery x-ray machine launched by Perlove medical, with multiple dose protection technology support, such as intelligent dose control technology, according to different body types and different parts of the body, accurately adjust the dose of the projection, so that the operator in any use of the environment, can be realized in the low dose, diagnosis and visualization of the image of a clear effect; beam limiter preview function, through the observation of the screen to preview the range of the field of view of the effective exposure, you can Reduce unnecessary attempts caused by multiple exposures, thus reducing radiation damage to medical personnel and patients.
