What is difference between erpc and d&c?

Two different tests: ERCP is short for endoscopic retrograde cholangiopancreatography. It is a procedure that looks at the bile ducts. It is done through an endoscope. A dilation and curettage procedure, also called a D&C, is a surgical procedure in which the cervix (lower, narrow part of the uterus) is dilated (expanded) so that the uterine lining (endometrium) can be scraped with a curette (spoon-shaped instrument)

Two very different: ERCP-is endoscopic retrograde pancreatography which looks specifically at the pancreas and the ducts going into the pancreas. D&C is dilatation and curettage which is a procedure for the uterus.
