title: Adjustable gastric banding: a comparison of models.
abstract: BACKGROUND
  There are several models of adjustable gastric banding in use with little evidence for choosing a particular model. The objective of this study was to evaluate factors for selecting a particular type of band in terms of weight loss, complications, and co-morbidities.
  
  
  METHODS
  From July 2006 to May 2012, 222 patients underwent laparoscopic adjustable gastric banding (LAGB) by a single surgeon. Patient demographic characteristics, weight loss, body mass index (BMI), percentage of weight loss (%EWL), complications, and co-morbidities were retrospectively reviewed. Patients were grouped according to the band model into 6 categories: 27 LAP-BAND Adjustable Gastric Banding System VG, 25 Allergan-LAGB, 20 LAP-BAND AP(M) Standard, 18 LAP-BAND AP(M) Large, 34 Realize Band, and 98 Realize-C band.
  
  
  RESULTS
  At 60 months follow up, in the LAP-BAND VG Group, the mean %EWL was 41%, percentage of co-morbidity improvement was 66%, and percentage of complications was 14.3%; the same percentages in the Allergan-LAGB Group were 41%, 0%, and 52%, respectively; in the LAP-BAND AP Standard Group were 42%, 20%, and 40%, respectively; in the LAP-BAND AP Large group were 38% , 12.5%, and 27.8%, respectively (at 48 months); in the Realize Band Group were 37%, 60%, and 0%, respectively (at 48 months); and in the Realize-C Band Group were 48%,12.5%, and 12.2%, respectively (at 36 months).
  
  
  CONCLUSIONS
  In terms of weight loss and co-morbidities, no differences were found supporting the choice of one model over the others. Short-term and long-term band-related complications occurred without any clear predilection. The port-related complications were significantly lower in the Realize bands.
