how do you know if this has happened?? should you feel anything?? pain?? 

Some people have pain and some don't.  You may have trouble getting food to stay down, you could have pain in the sternum or chest... but a fluoroscopy Xray is probably the best idea to determine whether or not the band is correctly positioned.

I was diagnosed with this problem just this week.  I had been having pain at the sternum and every night and often during the day I would have a huge amount of acid reflux.  I would cough all night due to the acid.  So glad that I went to my Dr. and had a fluroscope done.  I had all of my saline removed and I am suppose to be on liquids for 3 weeks and then return for another fluroscope.  Dr. Said that if the band did not reduce that I may need surgery.             Has anyone had this problem and ended up having surgery?

Here is a good explanation on what causes pouch dilation and treatment,

good luck.

Postoperative complications:
Pouch complications

Pouch dilatations (Enlargement of the pouch)

Fig. 10: Concentric pouch dilatation

There are several different forms; namely early and late stage, and acute and chronic pouch enlargements. An early dilatation may occur a few weeks after surgery; this is usually caused by an incorrectly positioned band. The main effect of this is creation of a pouch that is too large. The late-stage form manifests itself after weeks, often even after a year, and is usually caused by abnormal eating habits like meal sizes that are too large (possibly even pre-operative binge-eating), or a gastrostoma that is too constricted. This may also include sliding hiatal hernia (diaphragmatic hernias with an upwards-shifting stomach entrance) in front of an otherwise well-positioned band. Radiological visualisation will show a concentric pouch. If left untreated, the dilatation may progress into real "slipping," including upwards-shifting of the stomach wall below the band.

Slippage

Fig. 11: Dorsal Slipping

Shifting upwards of the rear (dorsal slipping) or front (anterior slipping) stomach wall through the band. This is a typical post-stomach-band operation complication, mainly caused by operational cir****tances. As described in international literature, it is nowadays reduced to below 1%. Upon introducing a contrast medium, the pouch will look excentric on x-rays. Mechanism: Due to the enlargement of the pouch, a valve-like mechanism occurs, in which passage to the main stomach is progressively obstructed by parts of the stomach wall (partial to complete stoma occlusion). Passage in reverse order is still possible though (reflux from the main stomach to the pouch or the oesophagus).

Ailments and symptoms

There are acute (suddenly occurring) and chronic ailments, which occur similarly in both forms of pouch complications. While pouch dilatation initially causes meal sizes to become larger followed by vomiting, subsequently, as the pouch gets increasingly larger, a similar situation as with slippage can occur, in which parts of the stomach wall can cause a shift of the gastrostoma or other inflammations progressively obstruct the passage. This is reflected in intolerance towards solid foods and then to liquid foods until there is a complete stoppage in passage.

Chronic:

• Increasing passage disorders for solid foods; Repeated vomiting after meals; Regurgitations (back-flow of food-remains, burping****urring at night also.
• Progressively increasing capacity limitations even for liquids; Drinking only possible in little sips; solid foods not tolerated anymore at all.
• Excessive weight-loss, reflux symptoms (pain or burning sensation behind the breast bone), general complaints like tiredness, deficient nutrition
• Any chronic form can escalate into an acute form.

Acute:

• Complete halt of passage (total food intolerance)
• Consequences of untreated total food intolerance: Dehydration (fluid deficiency), shock condition (reduction in blood volume), electrolyte imbalance (disturbed blood/salinity balance), prerenal failure (kidney failure caused by dehydration), extremely heightened risk of aspiration mostly at night (breathing reflux stomach contents into the airways causing a risk of pneumonia)

Therapy

a) Conservative

If dilatation caused by an overly constricted stomach band occurs in isolation, without any upwards shifting of stomach wall parts, then conservative therapy should be sufficient.

• Completely opening the stomach band (decongest)
• Insertion of a gastric tube to relieve the pouch and avoid aspiration
• Immediate rehydration (administration of fluids), balancing electrolytes via IV (intravenous infusion of saline solution)
• Administration of antacid (e.g. Omeprazol): to protect against or treat mucosal changes within the pouch
• Deficiencies: Substitutive therapy (iron, vitamins, etc.)
• Parenteral nutrition (feeding completely by infusing into a central vein): Seldom; Only in cases of decompensation combined with malnutrition, where enteral nutritional intake is not possible despite decongestion of the band and other measures.

b) Re-operating

Laparoscopic revision is demanding and requires extensive experience in this technique. Most of the time, a replacement of the stomach band or a repositioning using the laparoscopic technique is sufficient.

• Band repositioning:
  Repositioning of the band without exchanging it is usually only possible in the early stages of pouch complications; however, it is almost always done using the laparoscopic technique. The part of the stomach that has slipped upwards through the band is pulled back down, and the band is then re-fixated. This requires that there be no extreme concrescences to the band itself and that the pouch not be highly vulnerable due to inflammation.
• Band replacement:
  If late pouch complications occur (after months or even years), the stomach band will have to be replaced, usually using the laparoscopic technique. When doing so, it is cut close to the seal and pulled out of its connective tissue membrane, and a new band is inserted in the proper position.

I am tryn to find out is me just not feeling full aftr eating mean its stretched? I have no pain

So funny, AFter years out of touch with my Band-Friends, I came back because of this problem. Last November I was having this terrible pain, no reflux, just pain, everytime I ate or dran something, even water. I went to see my doctor (not my original, I have switched due to distance) and he had performed the X Rays with the chalky stuff. He proceeded to take out 2 cc's and since then the pain is gone but my appetite is back with a vengeance. I have gained 15 lbs and I can;t find my way back. He refuses to put the 2 ccs back I tell him that I had those 2 ccs for two years prior and it was working great, but he says that my restriction is good. Now, how in the world can he tell me that when I have gained so much weight back and 20 minurtes to half an hour after I eat, I am hungry again! I am goign back to see him on the 26th and If I don;t get some good explanation on why can I get my 2ccs back, I am leaving this doctor. All he wants me is to have the strength to conquer my appetite. Well, If I could do that, I didn't need this band to start with. What can I do?
