How does rectum cancer terminal hematochezia return a responsibility

summary

Rectal cancer is a kind of lifestyle disease, from the dentate line to the junction of rectum and sigmoid colon, is one of the most common malignant tumors in the digestive tract. In Beijing, the complication rate of rectal cancer is higher and higher, and its mortality is also in the front row. Hemorrhoids' blood is generally bright red, rectal cancer's blood is generally darker than hemorrhoids' blood; hemorrhoids' blood is often drop by drop, rectal cancer's blood volume is sometimes too much; although hemorrhoids and rectal cancer's blood are first blood and then stool (and gastric bleeding mostly first stool and then blood), rectal cancer sometimes often has blood and stool dissolving. However, this is only a general situation. If bloody stool is found, it is recommended to seek medical treatment in time. Now I would like to share with you my experience on how to deal with hematochezia in the late stage of rectal cancer.

Reason 1: Rectal chronic inflammation: chronic ulcerative colitis, granuloma caused by chronic schistosomiasis are directly related to the occurrence of colorectal cancer. The longer the course of disease, the higher the possibility of colorectal cancer. The incidence of colorectal cancer in patients with ulcerative colitis more than 20 years is about 20% to 40%.

Reason 2: diet and carcinogens: the occurrence of colorectal cancer is obviously related to economic status and diet structure. The incidence rate of fat and protein in the economically developed areas and the low proportion of animal cellulose and protein in the developed areas is obviously higher. The exact mechanism of the relationship between dietary structure and colorectal cancer is not fully clear. It is generally believed that it may be related to the metabolites of animal fat, bacterial decomposition products, intestinal peristalsis slowing down and intestinal toxin absorption increasing due to low cellulose diet.

Reason 3: genetic factors: in addition to colorectal cancer patients caused by familial polyposis or ulcerative colitis malignant transformation, about 5-10% of other colorectal cancer patients have obvious family tumor history, which is collectively referred to as hereditary non familial polyposis colorectal cancer.

matters needing attention

Patients with rectal cancer should timely understand the nursing of artificial anus, and the use of artificial anus bag should also be mastered. Before using the artificial anal bag, the surrounding skin should be cleaned and nursed. After using, attention should be paid to the hygiene of the anal bag to avoid cross infection
