Director Wang is a medical staff member of the hospital. A few days ago, the old mother who had intermittent blood in the stool for a long time was brought to Beijing from her hometown for radical surgery for colorectal cancer. Postoperative pathology showed multiple lymph node metastasis, and the condition was in the middle and late stages. Do not perform sequential adjuvant radiotherapy and chemotherapy. Chief Wang is a clinician himself. Why has his mother not been diagnosed and treated with blood in the stool for so long? This has to start with the impression of blood in the stool. It is said that "ten people have nine moles", and with the economic development, the pace of life is getting faster and faster. The high-fat, high-energy diet and sedentary lifestyle promote the increase in the incidence of hemorrhoids, but not all Blood in the stool is caused by hemorrhoids.
The definition of blood in the stool is simple and complex. The simplicity refers to the blood in the stool, and the complexity lies in the way the stool combines with blood. It is mainly divided into two types: the surface of the stool cannot be seen with the naked eye and the blood can be seen. Subdivided from the blood in the stool that can be seen by the naked eye, it can be divided into blood on the surface of the stool at the beginning of the stool, blood on the surface of the stool during the whole process of defecation, and blood in the stool. In addition to hemorrhoids, the most common diseases that cause blood in the stool include peptic ulcers, intestinal polyps, inflammatory bowel diseases, and gastrointestinal malignancies. Peptic ulcers, multiple intestinal polyps, and inflammatory intestinal polyps all have A disease with a higher tendency to become cancerous.
The common blood in the stool of peptic ulcer is mainly melena or positive occult blood in the stool. Because upper peptic ulcer bleeding fades the bright red color after the action of gastric acid in the gastrointestinal tract, it is generally not easy to see the bloody stool caused by the ulcer. Peptic ulcer is a high-risk disease in China, and most of these diseases can be cured after standard, full course of treatment and regular review. However, because most people think that they have more knowledge about such diseases, they often buy some acid-suppressing drugs or gastrointestinal mucosal protective agents to take them by themselves, starting from "no pain is good", without formal treatment and regular review It is often unknown that the disease has undergone early canceration. It is not until a series of symptoms such as uncontrollable pain, black stools, weight loss, and loss of appetite appear, that the examination is performed. It is often in the middle and late stages of the disease, and the best treatment opportunity is lost. Therefore, if you suffer from such diseases, the first thing to do is to carry out standardized treatment. When the condition is repeated or the symptoms change, timely gastroscopic biopsy and other inspections can be performed to prevent the occurrence of cancer at an early stage.
Intestinal polyps cause blood in the stool mainly because when the stool passes through the polyp, the friction causes the local surface of the polyp to rupture and hemorrhage, and blood in the stool can be seen throughout the process. Familial hereditary colon polyps are the most important high-risk factor for colorectal cancer and have a high tendency to become cancerous. The main treatment method is to remove the polyps to remove the roots and completely eliminate the possibility of polyps becoming cancerous. For the excised polyps, pathological sections are required to rule out the possibility of early canceration. One resection does not guarantee permanent immunity, and regular colonoscopy is required to determine whether there are new polyps or recurrence of cancer at the base of the polyps previously removed.
Ulcerative colitis and Crohn's disease are both intestinal inflammatory diseases. The bloody stool is mainly mucus, pus, and bloody stool, which is quite different from the bloody stool caused by hemorrhoids or intestinal polyps, and it is not difficult to distinguish. Intestinal inflammatory diseases such as ulcerative colitis and Crohn's disease are currently not cured, and their long-term cancer risk is quite high.
Therefore, no matter the blood in the stool caused by the above-mentioned diseases, or the blood in the stool directly caused by malignant tumors of the digestive tract, we should pay great attention to us, and we should not simply "deceive" ourselves with hemorrhoids or constipation. So we can say that blood in the stool is an alarm signal for gastrointestinal tumors. Sound the siren early to eliminate the tumor in its budding stage!
