Editing Vertical Banded Gastroplasty


== Purely restrictive procedure ==

* Upper part of stomach     partitioned by a vertical staple line with a tight outlet wrapped by a     prosthetic mesh or band
* Upper pouch fills quickly     with solid food and prevents consumption of a large meal
* Effectiveness depends on     durability of pouch and stoma (outlet) size
* Not beneficial for those     eating calory-dense foods
* Unsustained weight loss
* High incidence of     complications requiring revision


== Complications ==

* Staple line disruption
* Stomal stenosis (20-33%)
** Occurs either due to      fibrosis of the stomach or by the band itself
** Try endoscopic dilatation      initially, but it might be unsuccessful due to the rigid nature of the      prosthetic band (overall success rate 68%)
** Symptoms likely to return      after dilatation
** Surgical revision can be      quite difficult due to dense scarring
* Band erosion
* Band disruption
* Pouch dilatation
* Vomiting
* GORD
** Late complication which may      reflect stomal stenosis and pouch dilatation
** If unresponsive to maximal      medical therapy, may require conversion to RYGB or reversal
