What are the differences between a proctoscopy and a colonoscopy?

Intestinal health is very important to people's bodies, and the intestines are an important place for digestion and absorption. Once problems occur, it will cause more serious health damage. The two most commonly used techniques for diagnosing intestinal diseases are colonoscopy and proctoscopy. Both techniques have certain characteristics. Let’s take a look at the differences between colonoscopy and proctoscopy. I hope everyone can understand.

1. If the rectum and colon are located in different positions, colonoscopy is generally chosen, which is also the basis for early diagnosis of intestinal malignant tumors. After the examination is clear, surgical treatment should be the first choice, and then postoperative adjuvant chemotherapy should be performed according to the stage to reduce the chance of postoperative recurrence. Among them, the chance of cure for colon cancer in an earlier stage is relatively high.

2. Sigmoidoscopy can only see the rectum and sigmoid colon. The currently used electronic colonoscope can examine the following parts: rectum, sigmoid colon, descending colon, splenic flexure of the colon, transverse colon, hepatic flexure of the colon, ascending colon, cecum and terminal ileum, and can examine the entire large intestine.

3. Colonoscopy is used to examine the colon, while this proctoscopy is only used to examine the rectum. It is impossible to examine the colon. Generally speaking, the colon is longer and includes the rectum. If a colonoscopy is used, the rectum can be examined, but if only a proctoscopy is used, it is impossible to examine the entire colon. It is recommended to do a colonoscopy if chronic ulcerative sigmoiditis or chronic ulcerative proctitis is diagnosed. It is an inflammation that occurs in the sigmoid colon and rectum. Generally, enteritis can be congested and edematous, erosive and ulcerative, or ulcerative and hemorrhagic. It can cause pain, bleeding, anal urge to defecate, tenesmus, and can cause pus and mucus in the rectum. The diagnosis is relatively clear. It is recommended to use special enteritis oral medicine and enema treatment. Generally, 3-4 courses of treatment can be sufficient to cure the disease. In some extremely serious cases, 4-6 courses of treatment are required to completely cure the disease.
