Tumours of the small intestine

Cancer of the small intestine is only 3-4% of all colon cancer and is found more often in men aged 40-60 years.
Cancer of the small intestine, usually circular distributed in the intestine in the form of polypoid expansion or in the form of colored cabbage, serving in the intestinal lumen, or infiltrating tumor growth leads to a circle narrowing of the lumen of the intestine. Microscopically in most cases is set adenocarcinoma, at least - a solid and even more rarely - mucous cancer. The fact that cancer of the small intestine late grows serous cover it explains rare contamination cancer metastases peritoneum.
As for the transfer of cancer to the lymph nodes of the mesentery and regularities of metastasis in a separate bodies, these issues are reflected in a special manual of Oncology.
Symptoms for cancer of the small intestine in the beginning of tumor development is very poor: progressive anemia, fever, lack of energy, weight loss. Over time, there are signs of narrowing of the bowel or ulceration it, but it already takes place far stalled the process. Periodically there are abdominal pain and symptoms of intestinal obstruction. The tumour localization in the upper division of the jejunum is accompanied by a clinical picture that is similar to the pyloric stenosis, and differential diagnosis becomes possible only with the help of x-ray studies.
Cancer ileum is characterized by typical symptoms gradually coming obstructive ileus.
Sometimes sudden pains in the stomach are called intussusception on the site of the tumor. Pitting the last can cause profuse bleeding.
Surgical treatment of cancer of the small intestine at any level is resection of the affected area it together with the lymph nodes of the mesentery.
Sarcoma of the small intestine, A. I. Abrikosov, 1-2% of all sarcomas in humans. The disease often affects younger age (20-40 years).
Sarcoma of the small intestine occurs in the form of nodes on a broad basis, sitting on the serosal surface or wystawa in the bowel lumen, sometimes in the form of a polyp on the leg.
In some cases sarcoma cancer is of a diffuse character and occupies a considerable portion of the intestine. Sarcoma unlike cancer do not cover the gut circular and, thus, do not create conditions for occurrence of obstruction. The tumor is rapid growth in the direction of the mesentery and lymph node cancer, and hence in the retroperitoneal space. Early appear metastases in the liver, kidney, pancreas, lung, and peritoneum, and in most of these cases early may experience ascites.
Histologically, the tumor is a round-cell sarcoma or difficult to discern from her lymphosarcoma.
Symptoms of sarcomas of the small intestine characterized by nausea, vomiting (especially at high localization), diarrhea, alternating with constipation, sometimes significant intestinal bleeding, quickly leading to anemia and malnutrition. Unlike cancer of the small intestine sarcoma often detected by palpation, in sarcoma is absent bowel obstruction. Diagnosis of sarcomas, despite these symptoms, remains very difficult.
Treatment - surgical and lies in extensive resection of the affected area of the colon. Forecast - nalogoblozheniya (A. A. Rusanov, 1960).
