The appropriate stoma size is achieved by inflating the band with saline rather than tightening the band. This is designed to increase adjustability and reduce the possibility of over- tightening. Two band sizes selected on the basis of the measurements on ASGB bands and early clinical use in Europe. Although most surgeons utilize the smaller size, some surgeons prefer to utilize a slightly modified placement procedure with the larger size. A circular-shaped inflatable portion of the band allows the band to inflate evenly and smoothly without significant folds or creases.
Folds can result in differential pressure on the stomach as well as pinching of tissue.
These could result in tissue necrosis and subsequent erosion. The folded, creased silicone eventually weakens and leaks. The LAP-BAND System is designed to avoid these problems. Radiopacity of all components. This avoids the need to use a radiopaque liquid such as is used in other bands.
