My son had a gtube for 25 years. He had it taken out. When they took it out they just left the stoma open. After 25 years it wasn't going to close on its own. Every time he ate or drank , stomach acid oozed out of the stoma. He was in a tremendous amount of pain. He developed cellulitis from the skin break down. He had to be hospitalized and the stoma closed surgically from the inside and the outside.He recovered and has done fantastic. Some stomas that haven't been in long do close on their own. I'm not sure how long you've had the stoma and I don't want to frighten you. I wish someone would have told me to have the stoma closed surgically and spared my son a lot of pain. I wish you well!!
