Is it possible for an appendix to rupture and then seemingly disappear?Our daughter has been in the hospital for 4 weeks,with an infection in her bloodstream,gallbladder and kidneys.The doctors have been unable to determine why her abdomen keeps filling up with purulent drainage,that they have removed by syringe 5 times,until today they took her to operating room and thru a 6 inch incision removed over a gallon of infectious fluid.The surgeon says he cannot find any reason for this infection,except he could not find her appendix.Before she got sick 4 weeks ago she was a very healthy 26 year old,2 weeks from graduating college.She now has 2 drain tubes in her abdomen and a NG tube.Please advise.Thank you
