Erosion and slippage?

[Nemesis 0]

Why and how do these things occur? If these things happen, is that it - you're done with the band?

How often do these things happen?

Thanks

What is a slipped Band, and what causes it?

There are two types of slippage; anterior and posterior. This refers to whether the front or back side of the stomach slips. There is something else called concentric pouch dilation, but this is not the same as slippage. Slippage or prolapse is when the stomach slides up through the Band, making the pouch bigger. If this happens the Band usually becomes too tight, and patients experience symptoms of reflux (heartburn) as well as nausea and vomiting. This is because the amount of stomach being “squeezed” by the Band is increased, thereby obstructing the Band.

There are several causes. Posterior slippage was more common when the Band was placed by the “perigastric” technique. With this technique the back side of the stomach was free to slide up through the Band. These days most surgeons use the “pars flaccida” technique, which was developed to prevent posterior slippage, and has more or less eliminated the incidence of this problem.

Anterior slippage is when the front of the stomach slips up through the Band. We try to prevent this by suturing the stomach below the Band to the stomach above the Band, “locking” the Band in place in the right spot. In spite of this, slippage still occurs. It can happen because we haven't placed enough stitches, or they haven't been placed in the right place. Slippage can also occur if patients eat too much and vomit frequently.

What is a Band erosion?

This is when the Band actually erodes into the stomach. It is a more serious problem, and generally requires removal of the Band. Band erosion is thought to be related to placing too many sutures (or too tight sutures) at the time of Band implantation. Surprisingly, Band erosion is often unnoticed. Occasionally the port will become infected if bacteria track along the catheter out to the port. Other times patients will stop losing weight. Diagnosis often requires an endoscopy.

Now, I found that on a website I visited for a school project (Laparoscopy.com). As far as if you are done with the band, no you are not. Plenty of people get the band replaced or repositioned and just resume their diets or adjust them as necessary.
