Diagram of Mystery Bump


and possible cut.

The red x is vague and now that I am looking at it probably on the wrong side of where the appendix is shown. I had my appendix out right before my son turned 1 and so that isn't there...unless the mystery bump is actually crohns inflamed appendectomy leftovers. (could be) Red line is also approximately where they will lop off intestine if they can't just lasso the mystery bump with the colonoscopy. I wish I knew where the doctor's funny little sketch was, I could scan that in.

And...just in case you weren't sure what the cecum did...
The cecum, the first part of the large intestine, is a sac with a closed end. It occupies the right iliac fossa, the hollow of the inner side of the ilium (the upper part of the hipbone). The cecum, also spelled caecum, is a pouch or large tubelike structure in the lower abdominal cavity that receives undigested food material from the small intestine and is considered the first region of the large intestine. It is separated from the ileum (the final portion of the small intestine) by the ileocecal valve (also called Bauhin's valve), which limits the rate of food passage into the cecum and may help prevent material from returning to the small intestine.

In humans, the cecum's main functions are to absorb fluids and salts that remain after completion of intestinal digestion and absorption and to mix its contents with a lubricating substance, mucus. The cecum's internal wall is composed of a thick mucous membrane through which water and salts are absorbed. Beneath this lining is a deep layer of muscle tissue that produces churning and kneading motions.

The structure and function of the cecum varies in other animals. Vertebrates such as rabbits and horses, which live on a diet composed only of plant life, have a larger cecum that is an important organ of absorption and contains bacteria that help digest cellulose. Animals that eat only meat have a reduced or absent cecum.

For anyone who may check-in here... TW's surgery went well. No bowel resection. She's in overnight due to pain and stuff but expected to go home tomorrow.
