Colonic lipoma is a common non-epithelial benign tumor in the large intestine. The cells of the colonic tissue proliferate abnormally, showing an expansile growth, resembling the gradual expansion of a balloon, and grows relatively slowly. As the tumor continues to grow, it can compress surrounding tissues, especially in the proximal colon, with the cecum being particularly severe.
The etiology of colonic lipoma is not yet clear, and it may be related to environmental factors, genetic factors, dietary factors, and emotional and nutritional factors during pregnancy. Excessive fat accumulation may be an important factor. Lack of physical activity, lack of exercise, and frequent consumption of high-fat, high-cholesterol foods are risk factors.
What complications can colonic lipoma easily cause
Colonic lipoma commonly occurs in people aged 50 to 69, with more females than males. Patients often have no symptoms, and larger lipomas can cause abdominal pain, hematochezia, and changes in bowel habits. In rare cases, a mass can be palpated.
The etiology of colonic lipoma is not yet clear and may be related to environmental factors, genetic factors, dietary factors, and emotional and nutritional factors during pregnancy. To prevent colonic lipoma, one should maintain regular life, be more active, and exercise more. It is recommended to have a light diet and eat fewer high-fat and high-cholesterol foods.
In addition to clinical manifestations, auxiliary examinations are also indispensable means for the diagnosis of colonic lipoma. Common examinations include the following:
1. Under endoscopy, colonic lipoma presents as a yellow, soft, round mass. Larger submucosal lipomas often protrude into the intestinal lumen and some become pedunculated.
2. Sometimes yellow discharge can be seen during biopsy. Pathology shows mature fat cells and fibrous stroma to confirm the diagnosis.
3. X-ray shows a smooth intestinal lumen with pedicle or broad-based mass, characterized by unstable morphology. The filling defect can change shape with external pressure or evacuation during barium enema.
Patients with colonic lipoma should follow a light diet in terms of diet. Avoid fatty and greasy foods, eat more egg whites, and eat fewer yolks. Secondly, do more physical exercise and try to control weight.
The principle of treatment for colonic lipoma is local surgical resection. If it is not possible to remove it endoscopically or there has been necrosis of the intestinal wall or failure of the intussusception reduction, local excision treatment should be performed through laparotomy.
