My boyfriend is a 33 year old healthy male. 2 weeks ago he had a laprascopic apendectomy. He was discharged on percocet, he was readmitted 4 days later for severe abdominal pain that went right to left and moved to below his rib cage when he lied down. CT showed fluid in the abdomen and a drain was placed ~ 100 ml fluid was drained and he was discharged on flagyl and bactrin.  1 week later he is back in the hospital and had to have fluid drained again, this time from his pelvic area. His only symptom is severe abdominal pain, no fever, no decreased appetite, and he doesnt have an elevated WBC. No one seems to know what is causing this and they are running every test under the sun on the fluid (anearobic, aerobic cultures and fungal tests, gram stain...everything) Hes on dilodid for pain. Could there be another post surgical complication causing this?
HI. Thanks for your query for your boyfriend. The fluid can be due to peritonitis, in response to the bacterial infection by non-specific bacteria. Or you have to discuss some infections like Tuberculosis which takes many weeks / days to heal up. IT is possible that your friend is suffering from tuberculosis of the abdomen and anti-TB treatment can be started even on empirical basis as it has antibacterial properties on other bacteria too where they will be resistant to the routine antibiotics,
