Advanced symptoms of small intestinal tumor

summary

Small intestinal tumor refers to the tumor of small intestine from duodenum to ileocecal valve. The small intestine accounts for 75% of the total length of the gastrointestinal tract, and its mucosal surface area accounts for more than 90% of the total surface area of the gastrointestinal tract. However, the incidence of small intestinal tumors is only about 5% of the total gastrointestinal tumors, and small intestinal malignant tumors are more rare, accounting for about 1% of the total gastrointestinal malignant tumors. The exact etiology of small bowel tumors is still unclear. The clinical manifestations of small intestinal tumors are very atypical, which are generally related to the type, location, size, nature, obstruction, bleeding and metastasis of the tumors. Let's talk about the late symptoms of small intestinal tumor

Advanced symptoms of small intestinal tumor

1. It is a common symptom. It can be caused by ulceration on the surface of the tumor, intestinal spasm caused by stimulation of the intestinal tube, intestinal obstruction or intussusception. When the tumor is huge and protrudes into the intestinal cavity, it can cause intestinal obstruction; Tumor invasion of the intestinal wall can cause intestinal stenosis and obstruction. This kind of obstruction is more common in malignant tumors of the small intestine. Intussusception is mostly caused by benign tumors of the small intestine, which can be acute or repeated chronic. 70% of the cases have varying degrees of abdominal pain. In the early stage, it is mainly caused by tumor induced intestinal peristalsis disorder or pulling mesentery, and the pain site is corresponding to the location of the tumor, Generally, the pain around umbilicus is dull and distending, which is aggravated after eating, and does not attract the attention of the patient. If obstruction or perforation occurs, the abdominal pain is aggravated, and the patient often goes to see a doctor for it.

2. About 1 / 3-2 / 3 of the patients have bleeding due to tumor surface ulceration, most of which are occult bleeding, manifested as positive fecal occult blood test or black feces. Iron deficiency anemia can also occur for a long time, intermittent small amount of bleeding or even a large amount of fecal blood. The most common causes of bleeding are leiomyoma, sarcoma, hemangioma, adenoma and neurofibroma. Most of them are anemia due to long-term occult blood test, Occasionally, there is bloody stool or a large amount of fresh bloody stool, even shock. When massive bleeding occurs, it is accompanied by paroxysmal abdominal pain and bowel sounds, followed by fresh bloody stool. The location of tumor and the amount of bleeding are different. The stool can be brown, brownish red, sauce red to bright red. If massive bleeding occurs in the terminal ileum, the blood color is bright red. Hematemesis and tarry stool may appear in the proximal jejunum, The bleeding rate of smooth muscle tumor, hemangioma and malignant lymphoma is high. The extraluminal smooth muscle tumor may break down occasionally and cause intraperitoneal hemorrhage.

3. It is caused by intestinal stricture, obstruction, intussusception, compression of intestinal cavity or volvulus of intestinal tube. The occurrence is related to the growth mode of tumor. The growth mode is as follows: ① growing into the intestinal cavity: small polypoid tumors such as small intestinal adenoma, lipoma, fibroma, etc. often induce intussusception, with paroxysmal abdominal pain, vomiting, abdominal mass touching, and the symptoms will be relieved after the mass disappears, The above symptoms occur repeatedly, large tumors often block the intestinal cavity, chronic incomplete intestinal obstruction or acute intestinal obstruction symptoms, due to abdominal distension, abdominal mass is often not easy to be touched, ② infiltrating and growing along the intestinal wall: causing intestinal cavity annular stenosis, mostly in adenocarcinoma, the course of disease is fast, ③ growing outside the intestinal wall: this type of tumor usually appears symptoms when it is large, causing small intestine folding, Torsion, or tumor adhesion with the greater network, compression of the intestinal canal, or invasion of the surrounding intestinal canal, resulting in intestinal stenosis, obstruction, more common in small intestinal malignant lymphoma, adenocarcinoma, lymphosarcoma, early intestinal obstruction.

matters needing attention

After radiotherapy for head and neck tumors, you should take more products of nourishing yin and promoting fluid, clearing heat and reducing fire, such as balsam pear, carrot, tomato, lotus root, jellyfish and cabbage. The staple food should be semi liquid or rotten soft food. 2. After radiotherapy, patients with chest tumor may have lung radioactive fibrosis, weakened lung function, shortness of breath, chest tightness and cough symptoms. Therefore, they should take more nourishing yin and moistening lung, tonifying qi and nourishing blood, relieving cough and resolving phlegm products, such as wax gourd, towel gourd, coriander, spinach, walnut kernel, white fungus, mushroom, bird's nest, etc. 3. After radiotherapy, patients with abdominal tumor should take more products to strengthen spleen and stomach, nourish blood and replenish qi, such as coix seed porridge, hawthorn, eggs, pig liver, stewed turtle and fresh fish. 4. Radiotherapy can inhibit the hematopoietic function of bone marrow and reduce the counts of red blood cells, white blood cells and platelets. Therefore, we should strengthen nutrition and eat more chicken and fish. We can cook them by boiling, burning and steaming. We can also choose foods with more iron, such as animal liver. Kidney, heart, lean meat, egg yolk, etc.
