Jan and Roger, Thank you for the thoughtful and helpful feedback.
As I read my post back to my wife, I found an error. I had rectal cancer, not have. The cancer was found via a routine colonoscopy in Aug 2014. Very low in the rectum. Stage 1. I had concurrent radiation and chemo in Fall 2014. The rectum and part of the sigmoid colon (a total of one foot) and 17 lymph nodes were removed in Feb this year. The biopsy showed no residual cancer. The chemo/rad had worked. The cancer had ever gotten out of the inside of the rectum wall. To bad we didn't know, I could have kept my rectum, but technology is not there to be able to tell.
I noted Jan's comment about the ileocecal valve. I have to check on that with the surgeon. When he did the ileostomy take down, the end of the ileum was damaged and he cut off 4-5 inches. I understand damage to the ileum and the need to remove a section is fairly common.
The surgeon recommended Psyllium husks, which appears to be the active ingredient in Metamucil. Do you know of any difference or reason to change. One thing that always concerns me about the info on Metamucil is that it is referred to as a laxative. The last thing I would think that I need is a laxative, but I'm an engineer not a doctor. I'm teachable.
The gastroenterologist has me starting Cholestyramine (aka Questran). It is a suspension that addresses bile malabsorption. This is very interesting since the end of the ileum has a bile uptake function that I understand is supposed to remove bile before the stool passes into the colon. This seems to be committed to the Ileocecal valve as well from what I just read on Dr Wikipedia. I find this very interesting since my impression for the last 7 months is that my colon is inflamed. The Cholestyramine may help with that.
I had my first colonoscopy since the surgery yesterday. No polyps, yeah! The GI took a number of samples which should help determine if there is an infection. He also biopsied two small nodules that showed up on the most recent CT scan. My oncologist, Colo-Rectal Surgeon and GI all felt this was a swollen lymph node, probably due to infection. I'm glad they did the biopsy though to make sure. I get the results in 2-3 weeks. At that point, I will know if the Cholestyramine helps. If that has not done the trick, I will follow-up with the question on Lomotil.
Thanks again and Merry Christmas, John
