I've also had many obstructions. They are truly the worst. About 6 years ago I started taking an enzyme called serrapeptase and it absolutely helped dissolve the scar tissue around my anastomosis. I could actually feel the knots within the scar and today it's completely soft. I only took the enzymes for 6 months or less. I used Doctor's Best brand. And I've not had an obstruction since. I do still have a stricture at the site so I sometimes still have some discomfort and distention but not 1 obstruction.
Here's an article:
Or just google serrapeptase for adhesions.
I was also doing the SCD diet along with the serrapeptase which I think may have helped as well. But if you suffer from obstructions, it's worth a try for $20 or so. I'm not sure if this has been mentioned before as I have not read the entire thread!
