What is proctosigmoidoscopy?
Proctosigmoidoscopy is a procedure for examining the rectum, rectum and distal sigmoid colon. This may include the use of a proctoscope, sigmoidoscope or colonoscope. All these tools provide visual examination of the intestine as well as the ability to obtain tissue samples for biopsy. It starts on the right side of the abdomen as ascending large intestine . This part of the large intestine ranges from Cecum to the liver bend. The transverse large intestine then runs over the abdomen from the liver bends to the splen bend. At this point, the decreasing large intestine goes on the left side of the abdomen, to the sigmoid colon in the shape of the letter S, the rectum and the rectum. The rectum is usually about 4.7 inches (12 cm) long and ends at the rectum. The stool can be temporarily stored in the rectum until Defekuation. This type of examination can be designed for those who have a family history of inflammatory bowel disease (IBD), cancer or other diseases of the digestive tract. Among other symptoms that may cause a doctor to do ProctosIgmoidoscopy, includes previous polyps, unusual bloating or urinary tract problems.
In the preparation for the procedure, patients are likely to be given instructions for intestinal cleaning. The instructions for the preparation of an individual physician will vary, but may include a laxative and a clean liquid food for hours before the procedure and enema. The sigmoid large intestine must be without a stool so that the area can be thoroughly examined.
Used toolpro proctosigmoidoscopy is usually a sigmoidoscope, although Proctoscopes and colonoscopes can also be used. In general, a flexible range is preferred to a strict model for comfort. The chosen range is likely to have light, camera, bellows and biopsy tool.
During proctosigmoidoscopy, the doctor can use bellows to throw away air into the intestine. This inflates the area so that all areas can be visualized correctly with camerathe apparatus. If a polyp or other unusual lesion is observed, the biopsy tool may be inserted over the range to remove the tissue sample for laboratory analysis.
As with any medical procedure, there is a risk of proctosigmoidoscopy. With a range, there is a rare chance of perforation of the intestinal wall. If this happens, the operation may be necessary to repair torn tissue.
