• A cecostomy tube, or C-Tube, (like the MiniACE®) is a thin tube that is placed into your large bowel through a stoma in your abdomen. The MiniACE® can either be placed directly into the cecum (cecostomy) or through the appendix and into the large intestine (appendicostomy, MACE). The MiniACE® allows you to put a flushing (irrigating) solution directly into your bowel so you can perform an antegrade continence enema (ACE).
