Help with ascites

Hello everyone, my mom is an advanced pancreatic cancer patient. She had the whipple in July 2020, but the cancer came back a few different times starting in Dec 2021, but we were able to handle it through surgeries. She recently left an immunotherapy trial that targeted her particular genetic fusion. Unfortunately, it didn’t work and she began getting ascites during the trial. Since April, she had to get drained once every three weeks, but now it is 1-2 times a week. Does anyone have any advice on the best way to handle this? She has not received chemo and will he staring her first course very soon. The ascites is making her very symptomatic, but she feels a lot better once it is drained. I’ve heard some things about the at home catheter. Thank you for your advice
