Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. This is the stent associated infection I advice you should do culture and sensitivity from the J tube. This will tell us more about the sensitivity pattern of the organisms.. Taking drug according to the report will cure you at earliest. Please maintian good hygiene locally. This is equally important in treating the infection. Dressing and cleaning should be done frequently. Betadine and dettol used for dressing and polysporin ointment can be applied over the gauge piece for dressing. This is done in addition to the antibiotics. This bug is very notorious for its antibiotic resistant. It has capsules which with helps to resistant in the bacteria. Diabetes should be controlled optimally otherwise the infection won t be treated. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
