<Li> If the band does not surround the vertical (esophagus - to - duodenum) axis of the stomach but instead surrounds only a non-vertical (horizontal or diagonal) axis of the stomach, as by encircling only a side or portion of a side of the stomach, then the restriction on food passage will be less, weight loss will be reduced, and a painful kink in the stomach may result . </Li> <Li> In two reported cases, prompted by patients' reporting an absence of appetite suppression and of weight loss, investigation revealed that the band had not enclosed the stomach at all, instead enclosing only perigastric fat, with the effect that the passage of food was not restricted at all . In these cases, the patients experienced no additional adverse symptoms . </Li> <Li> Problems with the port and / or the tube connecting port and band--The port can "flip over" so that the membrane can no longer be accessed with a needle from the outside (this often goes hand in hand with a tube kink, and may require repositioning as a minor surgical procedure under local anaesthesia); the port may get disconnected from the tube or the tube may be perforated in the course of a port access attempt (both would result in loss of fill fluid and restriction, and likewise require a minor operation). </Li> <P> The following are the adverse effects of gastric banding as documented by the FDA . </P>
