Colon cancer can be diagnosed through X-ray examination

The symptoms of colon cancer are generally mild or not very obvious, and are often ignored and easily missed. Therefore, the diagnosis of colon cancer is very important. So how to diagnose colon cancer? Let's take a look at what the experts introduce.

X-ray examination

1. Barium enema examination: The intestinal wall at the cancer site is rigid and poorly distensible, the peristalsis is weakened or disappears at the lesion, the colon bag is irregular or disappears, the intestinal cavity is narrow, the mucosal folds are disordered, destroyed or disappear, and there is a filling defect. Barium-air double contrast radiography is more helpful in the diagnosis of colon cancer.

2. Abdominal plain film examination: It is suitable for cases with acute intestinal obstruction. It can be seen that the colon above the obstruction site is inflated and swollen.

Sigmoidoscopy and fiberoptic colonoscopy

Although the sigmoidoscope is 25 cm long, 75% of colorectal cancers are within the scope of the sigmoidoscope. Microscopic examination can not only detect cancer, but also observe its size, location and local infiltration range. Through the sigmoidoscope, tissue can be taken for pathological examination. Fiber colonoscopy can provide a higher diagnosis rate and has been widely used in China. Skilled operators can insert the fiber colonoscope into the cecum and terminal ileum, and can also take photos. It is indeed an ideal method for diagnosing colon cancer.
