A drug such as paromomycin or diloxanide must also be taken to get rid of all the ameba in the intestine and to prevent the disease from coming back. This treatment can usually wait until after the abscess has been treated.In rare cases, the abscess may need to be drained using a catheter or surgery to relieve some of the abdominal pain and to increase chances of treatment success. Outlook (Prognosis) Without treatment, the abscess may break open (rupture) and spread into other organs, leading to death. People who are treated have a very high chance of a complete cure or only minor complications. Possible Complications The abscess may rupture into the abdominal cavity, the lining of the lungs, the lungs, or the sac around the heart. The infection can also spread to the brain.
