What are the typical complications of colorectal cancer in clinical practice?

Many colorectal cancer patients are usually in a serious condition when they are diagnosed. Some patients even develop various complications of colorectal cancer. What are the common complications of colorectal cancer ? The following is an expert's introduction to the complications of colorectal cancer.

1. Intestinal perforation: Clinically, there are typical complications of colorectal cancer, such as abdominal muscle tension, tenderness, rebound pain, and crescent-shaped gas under the diaphragm on X-ray films, which can make a preliminary diagnosis.

2. Intestinal obstruction: Tumor enlargement can cause intestinal stenosis and obstruction of intestinal contents, leading to mechanical intestinal obstruction. However, in clinical practice, acute intestinal obstruction caused by tumor is not caused by complete obstruction of the intestinal cavity by tumor proliferation. In many cases, it is caused by local inflammatory edema, food blockage, or administration of mannitol during intestinal preparation on the basis of severe stenosis caused by the tumor. The main complications of colorectal cancer are abdominal pain, abdominal distension, cessation of anal gas and defecation, vomiting, etc.

3. Bleeding: Acute massive bleeding is a rare complication of colorectal cancer. Clinically, a large amount of fresh or dark red blood in the stool occurs once or repeatedly within a short period of time, and the amount of bleeding often exceeds 1000ml, leading to a series of symptoms such as increased heart rate, decreased blood pressure, cold liver, decreased urine volume, and even shock, which is often life-threatening.
