HIPEC after first line chemo

Hi,

My wife's oncologist recommends heated ip chemo following the completion of her first-line chemo. Treatment is done with 4 incisions in the abdomen. They wash the abdominal cavity with heated chemo drugs (Cisplatin?) for 90 minutes and suck it back out. Requires 1 day hosptal stay. He thinks this can help eradicate the remaining cancer cells as IV chemo may not be able to kill some of the cancer. Sounded reasonable to us. 

Did any of you have this? Any feedback, thoughts?

Thanks
