Rectal cancer is cancer between the dentate line and the junction of the rectosigmoid colon, and is one of the most common malignant tumors of the gastrointestinal tract. The location of rectal cancer is low, so it can be easily diagnosed by rectal finger diagnosis and sigmoidoscopy. However, because of its location deep into the pelvic cavity and complex anatomical relationship, surgery is not easy to be complete and the recurrence rate after surgery is high. The proximity of lower and middle rectal cancer to the anal sphincter makes it difficult to preserve the anus and its function during surgery, which is a difficult problem in surgery and is also the most debated disease in terms of surgical methods. The median age of rectal cancer incidence in China is around 45 years old. There is a trend of increasing incidence in young people. How to take care of rectal cancer after stoma surgery? 1.Diet: After stoma, because there is no anal sphincter, there is no conscious control of fecal excretion, but by adopting the method of regular and quantitative feeding, through the regulation of 2-3 months, it can make the intestinal peristalsis form a certain rule, so as to form the rule of regular defecation. Although there is no special restriction on the variety of food, it is better to avoid spicy and irritating foods and foods that cause heavy stool odor. Special attention should be paid to avoid eating unclean food and diarrhea-prone food to avoid frequent bowel movements that cause inconvenience to work and life. 2, protect the skin around the stoma: intestinal fluid and dilute stool can stimulate the skin around the stoma, causing peristoma dermatitis, pain, itching and erosion, so the skin around the stoma should be cleaned in a timely manner to keep the skin around the stoma clean, and the appropriate use of pine pollen, traditional Chinese medicine Qing Dai San, etc. sprinkled around the stoma, has a better effect on the prevention and treatment of peristoma dermatitis. 3, the correct use of artificial anal bag: the best use of transparent and good skin adhesion and less irritating artificial anal bag, in order to observe the color and situation of the stoma, to prevent dermatitis around the stoma, to avoid odor and fecal overflow. When using the pouch, choose the appropriate artificial anal pouch according to the size of the stoma. When the habit of defecation is established, according to the regularity of defecation, it is not necessary to use the bag after defecation, and it is enough to cover the stoma with a gauze pad to protect it.
