Intestinal cystic gas

Introduction Intestinal cystic gas is common in the intestinal sac-like gas accumulation syndrome, which is also called intestinal emphysema syndrome. It refers to the small sub-mucosa or subserosal small balloon with different sizes and appearance like polyps.

Cause

The cause of balloon swelling is unclear. When the pressure in the intestine increases in the lumen, the ulcer enters the intestinal wall along the interstitial space from the ulcer or ulceration. The low-toxic aerogenes enter the lymphatic vessels from the intestinal mucosa, and the gas is produced to form emphysema. The cyst looks like a polyp or lymphangioma, the cut surface is honeycomb-shaped, there is connective tissue around the cyst, and the cyst is inaccessible to the intestinal lumen.

The clinical symptoms are mild, and there may be pain in the lower abdomen, mucus, diarrhea, and air bubbles. Can cause gastrointestinal bleeding, intestinal obstruction, intestinal torsion, pneumoperitoneum and so on.

Auxiliary inspection:

1. X-ray direct signs have a circular circular volume accumulation along the double edge of the intestinal wall or along the long axis of the intestinal tube.

2. After filling, there may be a sac-like translucent area of the size of the intestinal wall or the cavity. Indirect signs may include pneumoperitoneum, mediastinal emphysema, interstitial small intestine or colon.

3. Fibrous colonoscopy can have a round pale blue polypoid soft tissue mass protruding into the cavity, biopsy can have venting and see cyst collapse.

According to clinical manifestations, X-ray examination, fiberoptic colonoscopy and biopsy, there may be venting and seeing cyst collapse are helpful for diagnosis.

Differential diagnosis

Pay attention to the identification of diseases such as intestinal polyps, lymphangioma, and intestinal tumors.
