Brief Answer:
redness of the internal lining of the bowel

Detailed Answer:
HI, thanks for using healthcare magic

The mucosa is the internal lining of an organ or surface.

In this case, mucosa refers to the internal lining of the part of the intestines (ascending colon and cecum)

Erythematous means red.

Erythematous mucosa of the ascending colon and cecum implies that the internal lining of this area of the intestines, is red.
This can sometimes occur if an area is inflamed due to trauma or infection or allergies (not so common in the bowel) and other inflammatory conditions (IBS- inflammatory bowel disease - these are associated with a lot of symptoms however and quite a few other changes in the bowel as well)

In many cases the redness, easily resolves once the cause that is found is treatable

Erythematous mucosa does not mean that there is any evidence of cancer seen

I hope this helps, feel free to ask any other questions
