Why my brother-in-law has stomach cancer stent issues at 49?

Hi doctor,

My brother-in-law has stomach cancer of a genetic type, and the doctors were going to take his entire stomach out. My brother-in-law was constantly vomiting and could not keep food or even liquid down. So, the doctor put a stent in after eight days, and he had intense pain for two days.

Now, the pain has subsided, but he still cannot keep any liquid or food down, as he vomits after a while. He has not had any nourishment in days, and his test showed that he is malnourished, and he still cannot keep anything down.

The doctors took an X-ray of the stent and said it is in place, but found two round things blocked, which I think are the gelatin from the jelly they gave him. So after this, a few hours later, he tried some liquid and a number of hours later, he vomited again. The doctor thinks it is the bowels and gave him an enema, but nothing has changed.

Tomorrow they are going to take an X-ray of the bowel.

1. What could be doing this?
2. Would he require a stent for the bowel?
3. What else can we do?
4. What questions should we ask, or what else can be done?

I appreciate any information, as the poor guy is being left aside waiting and not really getting much quick help. We do not want him to die malnourished either, since nothing else is being done. He is 49 years old.

I appreciate your help.
