I have had esophageal dialation called a mega esophagus and not from over eating either, you can develope this from having a too tight band when food does not pass through the esophagus to the stomach due to a narrow esophagus measuring about 2.3 mm in diameter means that the foods and possible liquids you take in cannot pass and there for it in my terms just sits and backs up, causing vomiting,reflux and a real bad time of it. My most current UGI showed that my esophagus had narrowed, nothing passing through it, reflux in the esophagus just sitting there no place to go. It was also diagnosed that I ahve a hiatal hernia and as long as the hernia is there I will always have problems and possible esophagus problems for the rest of my life. If you have a hiatal hernia then your not supposed to be banded until after it is fixed, I was told none was found during my surgery but now it surfaced, so did the hernia happen due to all the vomiting? and pressure I had? I can't say I am not a Dr.
However my Surgeon had his office person send ina pre-determination letter to ahve the band removed and convert me to the RNY. I am still waiting for an answer. My Band has been completely emptied, placed on 2 weeks of liquids and 4 weeks pured foods and anopther UGI to follow. This is not my first time around with this same problem, for it has persisted now 2 years and enough is enough in my book. The Hiatal hernia was actually seen on my UGI from June 2010 and we are now just being told of this. What took so long? got me I was not the one reading the scan results, you cannot go by paper documentaion from the radiologist for they might not report it.
