Early symptoms of small bowel cancer Small bowel cancer can have symptoms such as bloating, discomfort and indigestion at the earliest stage, and then there will be changes in defecation habits, such as increased defecation, diarrhea or constipation, and abdominal pain before defecation. There will be mucus stool or mucus purulent bloody stool later.
Small bowel cancer will have poisoning symptoms in the early stage. Due to tumor ulceration, blood loss and toxin absorption, patients often have early symptoms of small bowel cancer such as anemia, low fever, fatigue, emaciation and edema, especially anemia and emaciation.
Intestinal obstruction is characterized by incomplete or complete symptoms of low intestinal obstruction, such as abdominal distension, abdominal pain, constipation or constipation. Physical examination shows abdominal bulge, intestinal type, local tenderness, and strong bowel sounds can be heard.
Prevention methods of small intestinal cancer 1, reducing animal fat intake to prevent small intestinal cancer
Compared with low-fat women, women who eat high fat have an increased risk of small bowel cancer by 32%. Reducing the content of animal fat in food is helpful to reduce the occurrence of small bowel cancer.
2. Reduce energy intake appropriately to prevent small bowel cancer.
Most studies show that the total energy intake is related to the risk of small bowel cancer, and reducing the total energy intake may reduce the incidence of small bowel cancer.
3, dietary fiber to prevent small bowel cancer
Dietary fibres in food can increase the amount of feces and adsorb bile salts to dilute carcinogens in the intestine, thus reducing the occurrence of small bowel cancer.
Diagnostic method of small intestine cancer Urine 5- hydroxytryptamine determination: When carcinoid occurs in digestive system, if it originates from stomach, duodenum, jejunum, ileum or right colon, it secretes more 5- hydroxytryptamine, if it occurs in large intestine, it secretes more somatostatin. The level of 5- hydroxytryptamine in the blood of patients with small intestinal carcinoid is obviously increased. It is helpful to determine the nature of the tumor by measuring the level of 5- hydroxyindoleacetic acid, a degradation product of 5- hydroxytryptamine in the urine of patients.
X-ray barium meal examination: X-ray barium meal examination is mostly used for the examination of suspicious duodenal tumors, usually using relaxation barium duodenography.
Exploration by laparotomy: For patients who cannot be diagnosed clearly by the above examination methods, exploratory laparotomy is feasible when necessary.
Fiberoptic colonoscopy: Fiberoptic colonoscopy can be divided into fiberoptic duodenoscopy, fiberoptic colonoscopy and selective arteriography, which can significantly improve the diagnostic rate.
Treatment of small intestinal cancer Surgical treatment: Small intestinal cancer is mainly surgery. If the primary lesion can be removed early, surgical treatment is the most effective method. Because surgical resection of functional carcinoid tissue is the most effective way to relieve carcinoid syndrome, even if metastasis is suspected, we should seize the opportunity of surgery and actively carry out surgical treatment.
