Hi there, Thank you for your complete information.
I agree, in general, with your mother's doctors statements.
The most likely diagnosis is an obstruction of the intestine. From the CT scan, an area of the small intestine shows narrowing and partial blockage.
The bowel is a very long tube that starts at the mouth and ends at the anus.
From the mouth next is esophagus, then stomach, then small intestine (duodenum, jejunum, ileum), then the large intestine (ascending colon, transverse colon, descending colon, sigmoid colon) and finally the rectum and then anus.
Women who experience ovarian cancer can commonly develop blockages or obstructions in any parts of the bowel (except it is rare to have a blockage of the esophagus which is the part of the gastrointestinal tract that traverses the middle of the chest (from mouth to stomach)).
Blockages can occur from three major reasons:
--adhesions which cause the bowel to twist and block off,
-- from a narrowing of a segment of the intestine because of an inflammatory process such as diverticulitis
--cancer recurrence that presses on the bowel or grows into the bowel
Usually the cause of the blockage is clear from context, exam, labs, and xrays.
There are times where the only way to know the cause is to operate.
For your mother, the most likely casue of her blockage is an adhesion(normal CA 125, no tumor seen on scan)
Medically, the first important question for her doctor is, does she need surgery to fix this obstruction. It sounds like she has a partial blockage - that is most of the time, bowel movements get through. However, perhaps aggravated by certain foods, she develops a complete blockage.
The signs of complete blockage include:
-lack of bowel movements
Many blockages can be managed without surgery with resting the bowel, IV hydration, and sometimes decompression of the bowel by a suction tube in the stomach called a NG tube (nasogastric )..
However, there are times when surgery is necessary to fix the obstruction by resecting the affected segment of intestine. At that time, it will become absolutely what the cause is.
if you google "bowel obstruction" there are several good references.
