I already have a standard j tube and I am thinking about getting a button placed in it's place. My question is, since I had my j tube placed surgically, will they have to place the button in surgically also? I've heard of two different type of buttons, the bard and Mickey buttons. I'm not sure what the difference is or if one is better than the other for j tubes. If anyone on here had a button with for their j tube, can you tell me about your experiences? I'm seeing a surgeon on wenesday and I am nervous because of the switch. I am also talking to the surgeon about the gastric pacemaker to see if I am a canditate and get info as well. I'm very nervous so if anyone has advice please help!
