Recurrence Ca. Ovary. What we can do?

Mother's Ca. Ovary detected in July,2014. Standard treatment of 3 + 3 Chemos and debulking surgery given. Recurrence in peritonial region after one year with sbo. After that 4 chemos given and surgery done. But surgery is not succesful as doctors said that the disease is spread as granuales of sand so it is not possible to collect secondly small intestine is fully involved in the disease. So they just open the abdomen and close it without doing anything. It was on 3rd May,2016. After 15 days till today there is severe pain in the abdomen. No medicine is effective in controlling pain. And now from last 5 days there is lots of vomitting and the colour of vomit is green. What will be the situation now? What we can do?
