Blood in the stool is a common clinical symptom. After some people find blood in the stool, they are “suspicious” all day long and compare themselves with various symptoms on the Internet, and take their seats. Abdominal pain and blood in the stool are called “precursors of bowel cancer”. Is this statement accurate? Let’s see what the experts say.
Abdominal pain, difficult to get off the operating table
Recently, the Eighth Ward of the General Surgery Department of our hospital received an emergency referral call from a foreign hospital. A patient was examined in a local hospital due to acute abdomen and was determined to be appendicitis. Appendicectomy was performed. When the abdominal cavity was opened, it was found that the ileocecal region (ileum terminal) giant myxoma with ruptured. The local hospital could not handle it and requested an emergency transfer for treatment. After receiving help from the local hospital, Zhao Yuzhou, the director of the ward, immediately organized a surgical team to receive treatment. The patient received secondary surgical treatment within two hours of arrival and completed intraperitoneal hyperthermic perfusion within 3 hours. Due to the insidious onset of tumors and atypical symptoms, patients were misdiagnosed.
It is difficult to detect early asymptomatic
The intestinal tract refers to the digestive tract from the stomach pylorus to the anus. The human intestinal tract is about 7-8 meters long, including the large intestine and the small intestine. As the largest digestive organ of the human body, the health of the intestinal tract is very important. But with the improvement of living standards, it is more and more likely to have intestinal health crises, the most worrying of which is bowel cancer.
Colorectal cancer is a common malignant tumor with no obvious symptoms in the early stage, making it difficult to detect. By the time symptoms appear, it is usually in the middle and late stages.
Liu Ying, the deputy chief physician of the Department of Gastroenterology in our hospital, said that bowel cancer may have symptoms such as malaise, weight loss, and low-grade fever with or without obvious incentives. In addition, the symptoms are different depending on the location of the disease. Right colon cancer manifests as an abdominal mass and abdominal pain with complete or incomplete intestinal obstruction. Left colon cancer is more likely to cause constipation, blood in the stool, abdominal pain, diarrhea, and other symptoms; while rectal cancer is mostly manifested as blood in the stool, changes in bowel habits, and perianal pain and bulge. Colorectal cancer may also have corresponding symptoms due to local invasion and distant metastasis, such as an increase in stool frequency of more than10 times/day, and liver metastases may be accompanied by pain in the right upper quadrant or even jaundice. Blood in the sputum, if there is bone metastasis, it is often accompanied by pain at the transfer site or even a fracture! Therefore, it is inaccurate to say that abdominal pain and blood in the stool are precursors to bowel cancer.
Colonoscopy is the “gold standard”
Many people showed indescribable expressions when they heard about colonoscopy, imagining that a tube was about to be inserted into their delicate chrysanthemum. can accept silently. Is colonoscopy that painful?
The specific method of colonoscopy is to reversely extend a tubular colonoscope from the anus into the large intestine. There is a micro camera on the colonoscope. Through the camera, the doctor can observe whether there are polyps in the field, and can take tissue from the lesion for pathological examination. Therefore, if you want to know whether you have bowel cancer, a colonoscopy is very necessary. As long as you can clean your bowels and cooperate with the doctor’s actions, you can greatly reduce the pain, and the abdominal distension after the examination will not last for too long. It eased after two hours of exhaust. Now there is also painless colonoscopy, which is performed under general anesthesia and is pain-free.
High-risk groups should be checked annually
Liu Ying said that bowel cancer is preventable, and the canceration of bowel cancer is a very long process. During this process, corresponding measures are taken for treatment and prevention at various stages. It is recommended that people over the age of 50 should have a colonoscopy every year, and if there is no abnormality, they can be reviewed every 2-3 years. High-risk groups should undergo annual colonoscopy screening.
1. If one parent, sibling, or child has colorectal cancer, screening should be done once a year starting at the age of 45.
2. Those who have undergone radical resection of colorectal cancer, because of the risk of anastomotic recurrence and recurrence of colorectal cancer. A colonoscopy should be done annually within the postoperative period.
3. Familial adenomatous polyposis ( FAP ) is caused by congenital or acquired defects in the colonic adenomatous polyposis gene. Mutations in this gene, which mostly occur in the 20s and 30s, can lead to hundreds of adenomas in the colon. After the age of 40, almost all people who carry this gene develop cancer. Such family members should receive genetic counseling, regular colonoscopy starting at age 18, and prophylactic colectomy if adenomas are found!
