My mum had cancer of the colon and part of her colon and the nearby lymph nodes were removed. The surgeon joined rejoined the colon to the small intestines. She was fine after surgery and was discharged 6 days after the surgery. However, on day 7 she started having an infection and her abdomen started to get bloated. She was re-admitted to the hospital and a tube was inserted to drain the abdomen fluids, which are looked clear, but had some blood stains. I would like to ask if this is normal, and what should we do next. My mum is 75 and has most of her cartoid arteries blocked.
