I had to have my port replaced in April. The problem was that he could put Fluid in, but could not get anything out. It was not a problem with the port but rather a kink in the tubing that goes from the port to the band. My doctor used the same surgical sight, and it was done under conscious sedation, so I did not have to be put out. Recovery was very fast and I was even shopping with my mom less than an hour later, although I probably should have just gone home because when the anesthesia wore off I was sore. It was nothing compared to the first surgery, but still had pain at the port sight due to it having to be re-stitched to the abdomen wall, and I didn't have to go through the month of liquids/mushies again.
Hope this helps.
