when they do the zits marker test, they can see where the markers get stuck the most, like in most cases the markers reach the descending colon and stay stuck there, so years ago they used to do the resection and remove only the sigmoid or the descending colon, in hopes that it'll shorten the transit time and will give those patients the relief they need.
but over the years it was proven again and again that removing just a small part or even half of the colon is not enough and the remaining part ALWAYS kept causing further problems, so those who had only a resection had to go back and have the rest of their colon removed.
so now they know for sure that removing only part of the colon won't solve the problem. and to be even more accurate, they've come to a conclusion that even leaving the tiniest part more than just the rectum, that part can still cause MAJOR problems with obstractions, so now they know it's simply best to remove it all!
i remember you spasman, is your constipation getting worse? are you starting to consider surgery? well i just had the surgery on last Aug and so far i feel SOOO much better, but it's only been a month since, so i hope things don't slow down too much in the long run.
anyway i wish you the best of luck with what you decide to do!
