My sister has bladder CA, she had chemo from Jan-May, with surgical removal of bladder(Indiana pouch), small bowel resection for the pouch, hysterectomy, lymph node dissection 2 weeks ago. Last week she developed severe abd. distention treated as an ileus with NG. Little release of distention-today paracentesis for ascites. What would cause this? Is it mets? Troubled in Indiana
