Looking for a clinic in Fayetteville Arkansas for fill ins

Hi I am new to the Fayetteville Arkansas area. I moved here from Chicago and I am looking for a clinic or hospital that does fill ins for the Lap-band. I have had my band for 3 years as of February of this year and never had a fill in. I would like to get one now I have been at a weight stand still for a year now and looking to loose 40 more pounds. If anyone know where I can go please let me know. Thanks a bunch.
