Go to the hospital for anorectal examination, what are you most afraid of?
I think most people will immediately think of two words: colonoscopy!
Colonoscopy is the medical device that directly checks the health of the intestines, and it is completely different from the ordinary imaging screening program. It should be known that the intestine is originally a cavity organ, and the lesions that appear in the intestine may only be erosions and inflammatory reactions of the mucous membrane. Especially after cancer, it is difficult to find it in the initial stage with color ultrasound, CT and other examination methods.
The colonoscope is different, it is the use of a length of about 140 cm bendable, with a light source with a dangerous electronic camera at the end of the fiber hose, from the patient's anus slowly into the large intestine, the site of the large intestine lesion for direct observation, after the discovery of suspicious lesions, but also by the way to take tissue for examination or large intestinal polyp removal.
It is the most direct means of observing the intestines in all examination items, polyps, inflammation, cancer, etc., which can be exposed under colonoscopy.
However, it is after all a means of examination that enters the intestine, and patients not only need to expose private parts in the process of examination, but also may produce pain, so many patients are very repulsive to colonoscopy. In order to avoid pain, everyone is more inclined to choose painless colonoscopy, believing that performing in a painless state can not only eliminate shame, but also will not cause any discomfort.
So the question is, when colonoscopy is necessary, how to choose between painless and ordinary colonoscopy, and what is the difference between the two?
1. Ordinary colonoscopy
The difference between ordinary and painless colonoscopy is actually the difference in the word "pain". During the course of a general colonoscopy, most patients will experience discomfort, including abdominal distension and traction pain. When the colonoscopy turns through the intestine, there will be discomfort, which varies from person to person, mainly depending on how well you tolerate pain.
Because of this, there is a great drawback of ordinary colonoscopy, if the degree of pain discomfort of patients is not high, it is difficult to improve the degree of cooperation with doctors in the clinic, and even there may be a situation of giving up halfway.
However, ordinary colonoscopy also has several advantages, such as its examination cost is relatively low, does not require the cooperation of an anesthesiologist at all, the patient appointment time is relatively short, and the operation is more convenient.
Moreover, during the examination, any discomfort can be communicated with the doctor in time, which in turn reduces the risk of intestinal perforation.
2. Painless colonoscopy
The examination process of painless colonoscopy is no different from that of ordinary colonoscopy, except that it adds anesthetic administration on the basis of examination. Most painless colonoscopies are intravenously injected with anesthetic drugs, allowing patients to quickly fall into a state of anesthesia.
Since the pain nerve is thoroughly anesthetized, the patient does not have any pain sensations and consciousness during the examination. However, after the end of the examination and the patient's awakening, a small number of people also develop symptoms such as bloating, dull abdominal pain or traction pain;
I have to say that painless colonoscopy does have advantages, because there is no pain in the process, so the patient and the doctor have a higher degree of cooperation. However, painless colonoscopy also has disadvantages because it is not suitable for everyone, and its cost is relatively expensive, and the waiting time for appointments is relatively low.
In addition, although the safety factor of colonoscopy is relatively high and the probability of intestinal perforation is extremely low, the risk of intestinal perforation is relatively increased because the patient is in a state of anesthesia.
Written in the end: In clinical opinion, people over 50 years old, have a family history of bowel cancer, and have obvious symptoms of intestinal diseases (abdominal pain, irregular stool, long-term constipation, bloody stools) and other people should be screened for colonoscopy according to doctors' recommendations. It is the best and most highly used test for diagnosing intestinal diseases, and patients can choose painless or ordinary colonoscopy according to their actual needs.
