My 60 yr old mother underwent partial colectomy, temporary colostomy and apendectomy all at once 9 days ago. The day before yesterday we we were discharged from the hospital. She has been on soft diet for at least 5 days now. Yesterday she started vomiting green liquid. We have informed her surgeon and he has prescribed omeprazole once a day for the next seven days. Still her vomitting comtineous. Is this normal or is there anything else we can do? Thanks a lot.
