First off, so sorry...it sounds to me like you had an obstruction or blockage that may have been slightly higher up in the gut...usually, if there is an obstruction in the pouch, you still get some return when intubating...especially if you irrigate (pushing in water and pulling back on the plunger...Do Not Pull back too much or force it, (especially if you feel it pulling on the inside of the pouch), but sort of pull/push 10-20 cc of water multiple times causing a swishing of the water inside the pouch...it allows the water to better mix with the fecal matter and loosen things up
Prune juice helps, so does grape juice, green tea (not as well) and coffee...in that order...I have also used dietetic teas that basically work like drainO but beware...if you have a real obstruction or blockage in the gut it is not a good idea...it is only useful if the pouch contents are too thick.
Meat tenderizer or digestive enzymes work to break down the fibers of the contents... and allow things to flow better.
You may need to intubate more often, with warm water instead of cold (do not use hot!)...it helps.
I use Alli (the anti-fat pills) when eating high carbohydrate foods containing lots of fats (like pizza or cheese sandwiches)...it isolates the fat molecules and sort of coats the output in the fat and makes it evacuate better.
You will learn to differentiate between (I hope that you never have to or need to again but...) an intestinal blockage and a stopped up pouch.
With an intestinal blockage there are 2 kinds...total and partial...total blockages mean that nothing, absolutely nothing, can go into your system or you will throw up...a partial blockage means that things can go in (water, juice...) but no solids...both can cause pain, nausea, vomiting, dehydration and gas...
Walking helps, rolling on a pilates ball, heating pads, massage etc...
My general rule is 24hrs at home and then I hotfoot it to ER.
Hope that this helps.
