OVERVIEW
Lipomas are common non-epithelial benign tumors of the large intestine and are more common in the proximal part of the colon, especially in the cecum. The etiology of the disease is unknown and may be related to excessive intake and insufficient exercise. It is more common in women than in men. Clinical manifestations include abdominal pain, blood in stool, and change in stool habit. Surgical resection is the main treatment for this disease.
Etiology
The cause of the disease is unknown and may be related to insufficient exercise, lack of exercise, high-fat diet, and excessive intake of high-cholesterol foods.
Symptoms
Lipomas of the colon are more common in middle-aged and elderly women aged 50 to 69 years, and are less common in men than in women. Lipoma of the colon is asymptomatic when it is small, but when it is large, it may present with change of bowel habit, abdominal pain, blood in stool, intussusception, and occasionally palpable mass.
Examination
1. Endoscopic examination
Lipoma can be seen as a yellow, soft and round mass, and submucosal lipoma can be protruded into the intestinal lumen when it is large, and a few of them have tips. Biopsy can see yellow color flow out. Pathologic section can see mature fat cells and fibroblasts.
2.X-ray examination
X-ray can see a smooth intestinal lumen with a mass with a base or wide base, filling defect, variable morphology, and changing morphology with external pressure or emptying during barium enema.
Diagnosis
There is no specificity in the clinical presentation of colonic lipoma, which can be diagnosed if abdominal pain is accompanied by fat mass-like tissue discharged from the anus, combined with auxiliary examination. This disease should be differentiated from colonic smooth muscle tumor, adenoma and colon cancer.
Treatment
The principle of treating this disease is localized surgical excision. If it cannot be removed endoscopically or if necrosis of the intestinal wall has occurred, or if the reset of intussusception fails, it should be treated with open surgery and local resection.
Prevention
1. Regular diet, regular living, moderate activity.
2. Light diet, low fat intake, balanced nutrition.
