bowel gas

Bowel gas released behind closed doors lingers in the air, poisoning those who come along later.

It is noninvasive and sensitive, but the presence of bowel gas or obesity may limit its usefulness.

Bowel gas and digestive habits make it difficult to obtain a clear sonogram, therefore, a CT scan is a good substitution.

'Snapshot' flash may be superior to echo planar imaging in some instances, especially where appreciable amounts of bowel gas are present.

Computed tomography (CT) can help obtain more accurate anatomical information, and is unaffected by obesity or the presence of bowel gases.

Abdominal pain and cramping, bloatedness with abdominal distension (thought to be due to fermentative production of bowel gas) and mouth ulcers may be present.

This is especially true of early appendicitis before the appendix has become significantly distended and in adults where larger amounts of fat and bowel gas make actually seeing the appendix technically difficult.

Despite its name, a KUB is not typically used to investigate pathology of the kidneys, ureters, or bladder, since these structures are difficult to assess (for example, the kidneys may not be visible due to overlying bowel gas.)
