HI. I'm new in this G.I. field. I've been searching the net for information on endoscopes' numeric markings. But can't find any.
Can anyone please tell me what these markings mean. How do I know if the doctor is in the sigmoid, rectum, ascending, descending, transverse colon, esophagus, antrum, or duodenum by just looking at the numeric markings. I can see that the doctors are sometimes looking at the measurements to see how far they are into the intestines. With upper endoscopy, it's easier to distinguish but with colonoscopy.. the colon looks the same to me. Please... I'm really lost here. I'm just starting in this field and any info is GREATLY APPRECIATED.
Do you know of any book that a beginning GI LAb nurse can refer to for information. THANKS.
