Lap Band Tubing Twisting/ Flipping Intestines

I just had my second surgery to revise the tubing. First surgery, 8 wks ago Dr. simply repositioned tubing as my intestine flipped over the tubing. Pain came back last week and again I had surgery 2 days ago this time to shorten the tubing. I am still very sore but I am wondering if my intestines are bruised or is / did the shortened tubing find it's way back to my intestines? The Dr removed 6-8 inches of tubing. I have not been very successful with weight loss and wonder if this is partially to blame. However, I did find out I only had 4.2 cc's in my band when I was told by a nurse 10 months ago I had 7cc's. I go for my follow up next tuesday and getting more fill as I can and have been able to eat pretty much what ever I want. I dont ever get the "satisified" full sensation I tought ZI would. So far this has been just anohter failed diet. I am hoping that more fill will do the trick ??
