Few Data

There are only few data of gastrointestinal endoscopy in pregnant patients. Only 0.4% of all procedures are carried out during pregnancy. Case reports and some small retrospective studies are available. Because of physiological changes in pregnancy there might be special risks of endoscopy. There might be complaints which can be physiologic during pregnancy, but can be signs of gastrointestinal disorders, too. Therefore, indications for endoscopy are not always clear and easy. Safety of the procedures is also not well studied. Besides the risks of endoscopy, medication given to the mother, electrocoagulation and radiation exposure from fluoroscopy during endoscopic retrograde cholangiopancreatography might be harmful to the fetus. Endoscopy should only be done when indication is unquestionable and strong. Only FDA „A” and „B” category medication is allowed. Gastroscopy is necessary for bleeding and for patients with pyrosis going together with alarm signs. Nausea, vomiting, abdominal pain and fecal occult blood test positivity are not indications for endoscopy, only for gastroenterogical consultation. Sigmoidoscopy is recommended for indication of lower gastrointestinal bleeding and sigmoid or rectal mass. Only therapeutic endoscopic retrograde cholangiopancreatography should be performed. Obstructive jaundice and biliary pancreatitis need immediate endoscopic intervention. The fetus must be shielded from radiation exposure. Orv. Hetil., 2011, 152, 1043–1051.

ABSTRACT Introduction Endoscopic retrograde cholangiopancreatography (ERCP) is a relatively new endoscopic procedure combined with fluoroscopy that is performed for multiple diagnostic and therapeutic indications. It carries a known risk of radiation exposure to patients and staff. We aimed to examine radiation administration techniques and to measure the radiation dose delivered by these techniques. Methods This was a retrospective analysis of 437 ERCP procedures performed at a tertiary care hospital between April 2015 and April 2017. Results A total of 437 ERCP procedural charts were reviewed: fluoroscopy administration was endoscopist controlled (EC, n = 187, 42.79%) or technician controlled (TC, n = 250, 57.21%). The mean (and SD) fluoroscopy time (FT) was 2.107 ± 2.0 minutes. The mean (and SD) dose–area product (DAP) was 15,227.371 ± 16,784.738 Gy·cm2. The degree of ERCP difficulty was evaluated as recommended by the American Society for Gastrointestinal Endoscopy, and graded 1–4. Level I TC procedures had a mean FT and DAP of 1.600 minutes and 12,644.72 Gy·cm2, respectively. The FT and DAP values for level I EC procedures were 1.514 minutes and 12,966.71 Gy·cm2, respectively, as compared with level IV TC procedures (mean FT, 2.539 minutes; mean DAP, 19,469.94 Gy·cm2) and level IV EC procedures (mean FT, 4.890 minutes; mean DAP, 37,921.00 Gy·cm2). Conclusion DAP and FT are increased significantly in EC ERCP in American Society for Gastrointestinal Endoscopy 4 procedures. Comparison of the different degrees of difficulty indicated that there is a linear correlation between the degree of difficulty and both FT and DAP.

Although many interventions involving radiation exposure have been replaced to endoscopic procedure in the gastrointestinal and hepatobiliary fields, there remains no alternative for enteroscopy and endoscopic retrograde cholangiopancreatography (ERCP), which requires the use of radiation. In this review, we discuss the radiation doses and protective measures of endoscopic procedures, especially for ERCP. For the patient radiation dose, the average dose area product for diagnostic ERCP was 14–26 Gy.cm², while it increased to as high as 67–89 Gy.cm² for therapeutic ERCP. The corresponding entrance skin doses for diagnostic and therapeutic ERCP were 90 and 250 mGy, respectively. The mean effective doses were 3– 6 mSv for diagnostic ERCP and 12–20 mSv for therapeutic ERCP. For the occupational radiation dose, the typical doses were 94 μGy and 75 μGy for the eye and neck, respectively. However, with an over-couch-type X-ray unit, the eye and neck doses reached as high as 550 and 450 μGy, with maximal doses of up to 2.8 and 2.4 mGy/procedure, respectively. A protective lead shield was effective for an over couch X-ray tube unit. It lowered scattered radiation by up to 89.1% in a phantom study. In actual measurements, the radiation exposure of the endoscopist closest to the unit was reduced to approximately 12%. In conclusion, there is a clear need for raising awareness among medical personnel involved endoscopic procedures to minimise radiation risks to both the patients and staff.
