Hi everyone. I know I'm late coming to this discussion but I did have a feeding tube for a couple years and it did fall out several times. Each time I ended up hospitalized for several days after going to an ER. The first time it happened I lost consciousness and my wife called 911 because I appeared to be having a seizure. (I got tested and it turned out the fainting and "seizure" were apparently just some kind of anxiety attack because the test found no evidence of neurological problems.)
The second time I "lost" my tube it was because a silly black cat named Tex was sitting on my lap while I was connected to the feeding pump. Tex decided he wanted to do a dramatic dismount and leap onto the floor but he got tangled up in the feeding line and pulled the j tube right out of my abdomen. And it didn't hurt at all. In fact, I never noticed any pain when the tubes fell out.
On average, it seemed like I was going to the ER every six months to get a tube replaced. In fact, one MD in an ER told me and my wife that the tubes tend to deteriorate from exposure to digestive fluids and seldom last more than six months or so. However, when I asked a GI specialist about this, he adamantly insisted that some tubes can and do last as long as five years. He assured me that doctors are not deliberately installing tubes that need to be replaced every few months.
Anyway I was able to train myself to regain the ability to chew and swallow enough soft food so that I do not need the feeding tube. I stopped using it a few months ago, and then about three weeks ago it fell out. I am not going to have it replaced. I still have a stoma in my abdomen that is healing slowly. There was some kind of infection near the site when the tube fell out and I am taking Keflex for it but will be through with the antibiotic in a day or two.
I had some scary but inconsequential pain in the first few days after the tube fell out. It was intrusive enough that I took a Tramadol just so I would not have to think about it, but after a day or two it went away. I've been told I might experience a few pin-prick pains in my abdomen at random times over the next couple months but need not worry about the minor discomfort.
