Endoscopy in pregnancy.
Endoscopy is rarely required during pregnancy. The potential risks of endoscopy during pregnancy include foetal hypoxia due to sedative drugs and exposure to radiation. There is no evidence that endoscopy precipitates premature labour, and studies in this area have concluded that endoscopy during pregnancy is generally safe. There should be a strong indication for the procedure, which should be deferred whenever possible to the second trimester. Procedures should be performed without any sedation, or with the lowest dose of sedative medication. Radiation exposure should be kept to a minimum. Support should be obtained from specialists in obstetrics and anaesthesia. Indications for endoscopy during pregnancy are as follows: (1) gastroscopy: upper gastrointestinal bleeding, dysphagia, uncontrolled nausea/vomiting; (2) sigmoidoscopy/colonoscopy: rectal bleeding, diarrhoea; and (3) ERCP: choledocholithiasis, biliary pancreatitis. Sedative drugs, such as midazolam appear to be safe if used carefully. Radiation exposure during ERCP can be kept well below the danger level for teratogenicity.
