Symptoms of splenic flexure carcinoma of colon?

summary

Splenic flexure carcinoma of colon is a common malignant tumor of the digestive tract, which occurs in the colon. It is located at the junction of the rectum and sigmoid colon. The incidence rate is highest in the 40~50 year old group, and the ratio between men and women is 2 to 3:1. The incidence rate is third of gastrointestinal tumors. The main types of colon cancer were adenocarcinoma, mucinous adenocarcinoma and undifferentiated carcinoma. The general shape was polypoid and ulcerative. Colon cancer can develop along the intestinal wall, spread up and down along the longitudinal diameter of the intestinal wall or infiltrate into the deep layer of the intestinal wall. In addition to lymphatic, blood flow metastasis and local invasion, it can also spread and metastasize to the abdominal cavity or along the suture and incision surface. Patients with chronic colitis, colon polyps and male obesity were susceptible groups. Symptoms of splenic flexure carcinoma of colon? Let's talk about it.

Symptoms of splenic flexure carcinoma of colon?

1. The right colon cancer has a large right colon cavity with liquid feces. Most of the cancers are ulcerative or cauliflower like, rarely forming annular stenosis, and rarely causing obstruction. If the cancer rupture bleeding, secondary infection, accompanied by toxin absorption, can have abdominal pain, stool changes, abdominal mass, anemia, emaciation or cachexia performance.

2. The lumen of the left colon is thin and the feces are dry and hard. Left colon cancer is usually infiltrative type, which is easy to cause annular stenosis, mainly manifested as acute and chronic intestinal obstruction. The mass is small in size, without ulceration, bleeding and toxin absorption. Anemia, emaciation, cachexia and other symptoms are rare, and it is difficult to touch the mass. Colon cancer often has organ metastasis, distant metastasis is mainly liver. Lymph node metastasis generally spread from near to far, and there are also cross metastasis out of order. The probability of lymph node metastasis is higher after the cancer invades the muscular layer of intestinal wall. Colon cancer cells or cancer emboli can also be transferred through blood, first to the liver, and then to the lung, brain, bone and other tissues and organs. Colon cancer can also directly infiltrate the surrounding tissues and organs, fall off in the intestinal cavity, and can be planted on the mucosa elsewhere. Spread to the whole abdomen, can cause cancerous peritonitis, ascites and so on.

3. Other colonic spasms: X-ray examination showed small segment of intestinal cavity stenosis, with reducibility. Appendiceal abscess: a history of appendicitis, abdominal palpable mass, but X-ray showed mass located outside the cecum.

matters needing attention

Endoscopic minimally invasive treatment can be used for the lesions that can be cured by endoscopy in early stage cancer. The treatment method for middle and advanced stage cancer is a comprehensive scheme, which is mainly surgery, supplemented by chemotherapy, immunotherapy, traditional Chinese medicine and other supportive treatment, in order to improve the surgical resection rate, reduce the recurrence rate and improve the survival rate. The principle of surgical treatment: radical cure as far as possible, protect pelvic autonomic nerve, preserve sexual function, urination function and defecation function, improve the quality of life.
