where does the tube go in a colonoscopy
the large bowel
title: Colonoscopy text: Colonoscopy Colonoscopy () or coloscopy () is the endoscopic examination of the large bowel and the distal part of the small bowel with a CCD camera or a fiber optic camera on a flexible tube passed through the anus. It can provide a visual diagnosis (e.g., ulceration, polyps) and grants the opportunity for biopsy or removal of suspected colorectal cancer lesions. Colonoscopy can remove polyps as small as one millimetre or less. Once polyps are removed, they can be studied with the aid of a microscope to determine if they are precancerous or not. It can take up to 15 title: Replogle tube text: Replogle tube A Replogle tube is a medical device used in the treatment of babies with oesophageal atresia. It is a double-lumen tube which is inserted through the baby's nostril into the blind-ending oesophageal pouch and used to drain saliva. This avoids secretions overflowing into the trachea (windpipe) and causing problems such as aspiration pneumonia. Replogle tubes are flushed regularly with saline to help remove secretions. Normally, a Replogle tube is used only for hours or days while the baby awaits surgery, but in cases where surgery has to be delayed a Replogle may be needed for weeks or even title: Sigmoidoscopy text: cancer in the ascending or transverse colon (two-thirds of the colon). However, although in absolute terms only a relatively small section of the large intestine can be examined using sigmoidoscopy, the sites which can be observed represent areas which are most frequently affected by diseases such as colorectal cancer, for example the rectum. For the procedure, the patient must lie on his or her left side on the examining table. The physician inserts a short, flexible, lit tube into the rectum and slowly guides it into the colon. The tube is called a sigmoidoscope. The scope transmits an image of title: Proctoscopy text: Proctoscopy Proctoscopy is a common medical procedure in which an instrument called a proctoscope (also known as a rectoscope, although the latter may be a bit longer) is used to examine the anal cavity, rectum, or sigmoid colon. A proctoscope is a short, straight, rigid, hollow metal tube, and usually has a small light bulb mounted at the end. It is approximately 5 inches or 15 cm long, while a rectoscope is approximately 10 inches or 25 cm long. During proctoscopy, the proctoscope is lubricated and inserted into the rectum, and then the obturator is removed, allowing an unobstructed view title: Fallopian tube text: Fallopian tube The fallopian tubes, also known as uterine tubes or salpinges ("singular" salpinx) are uterine appendages, lined from inside with ciliated simple columnar epithelium, leading from the ovaries of female mammals into the uterus, via the uterotubal junction. They enable the passage of egg cells from the ovaries to the uterus. In non-mammalian vertebrates, the equivalent structures are called oviducts. Its different segments are ( near the ovaries to near the uterus): the infundibulum with its associated fimbriae near the ovary, the ampullary region that represents the major portion of the lateral tube, the isthmus the visible medial third
