I don't care how much fluid you inject into the bowel, you DO NOT want to have any of this solution pass into the ilium, (small intestine.) The small intestine is not able to protect you from the assault of bacteria from the bowel. You would get a very nasty infection, and one that would be difficult to treat"
I have to respond to the post by Stephen S. I have Crohn's disease & in the summer of 2011 I had surgery that resulted in the loss of the last 3 feet of small bowel, cecum, appendix, ileocecal valve and 1 foot of ascending colon. Over the years, my colonoscopy prep has been about 48 - 52 hours of clear fluids,
1/2 the normal dose of MiraLax, Fleet Phospho Soda (till they took it off the market) or Movi Prep about 12 hours after I started clear fluids. During that time, I drink several cups of strong tea. My GI tract has ZERO tolerance to caffeine and that works almost as well as the oral laxative to clear the small bowel.
When that's done, it's enema time! I'll usually do 3 or 4 series of 2-3 enemas each, starting at 2 quarts and try to empty my 4 qt Sherema bag (Pictured in my avatar) on my last enema the morning of the procedure. I've only managed this 3 or 4 times.
Earlier this month, I had my first post-op colonoscopy (this was #37). During an office visit, prior to the procedure, I brought up the subject of the prep. Many years ago I told him about my use of enemas as part of the prep and he had no problem with it. He often mentioned my colon was unusually clean and I guess that made his job easier. I breathed a sigh of relief when he said ok, but stressed LOW PRESSURE, start with smaller enemas & work my way up and stop if you feel pain.
All were done in the Sims position (Even though I enjoy knee-chest), so the fluid would fill the descending , then transverse colon. The last enema on the morning of the procedure was a half cup shy of three quarts. I'm sure some fluid made it into the small bowel. There were NO ill effects, NO nasty infections. With the exception of the low pressure flow of chyme from the small bowel to the colon, what prevents the migration of intestinal flora in someone with no ileocecal valve?
YMMV, consult your MD about your use of large volume enemas. Be safe!
The one change I did notice was that evacuation took a good deal longer than I was used to. I guess peristalsis is more efficient when the ileocecal valve provides a barrier at the far end of the colon. I'm just THRILLED I can still have fun with my red bag! Colonoscopy results were minor inflamation at the anastomosis and biopsy results were CLEAN!!
