Soft Basket Band: a Novel Technique for Gastric Banding

biggest problem:5% pouch dilatationsin 1050 laparoscopic

gastric band procedures

Reasons for New Developments

Most common complications after gastric banding:

pouch dilatation slippage band migration mechanical malfunction

second problem:1,8% slippage*

in our 1050 laparoscopicgastric band procedures

(reoperation needed)

Reasons for New Developments

Most common complications after gastric banding:

pouch dilatation slippage band migration mechanical malfunction

* In literature, actual slippage of 4-6 % is usually found

Conclusion Main problems of AGB are complications such as:

proximal pouch dilatation which negatively affects quality of life slippage which requires an emergency re-operation

One possible solution to prevent proximal pouch from enlargement may be a mesh tied to a regular band to envelope the upper part of the stomach.

Results of this preliminary series are encouraging, considering that:

With the Soft Basket Band we had no gastric pouch dilatation or slippage, no disphagia, no need for re-operation for complications
