My husband was diagnosed with PC October, 2005. He went through months of chemotherapy and then chemo in conjunction with radiation. He had successful whipple surgery in October 2006. He then had follow up chemo for another four months. From January 2007 - he started having problems with ascites. He has gone weekly, and sometimes more frequently for draining. Thusfar, since January he has had over 165 liters removed. Today was another 9 liters. We too are looking for a more permanent answer to the fluid problem.
Good Luck and keep me posted on any information you might receive regarding this problem.
