title: Management of slipped adjustable gastric bands.
abstract: BACKGROUND
  A small percentage of patients undergoing laparoscopic adjustable gastric banding (LAGB) experience band slippage that might require subsequent surgical intervention. We present our experience with band slippage in 660 consecutive LAGBs performed since November 2001 in order to determine the optimal management for slipped gastric bands.
  
  
  METHODS
  The treatment options for patients with slipped bands include band removal, gastric reduction and reapplication of the original band, and band replacement. Data from electronic medical records, as well as telephone interviews, were collected and tabulated. The original weight and body mass index, weight and body mass index before the revisional procedure, and the most recent weight, body mass index, and percentage of excess weight loss are presented.
  
  
  RESULTS
  Of the 660 LAGB patients, 34 (5%) experienced band slippage and required 40 subsequent operative procedures. Of the 34 patients, 6 underwent multiple procedures for their slipped band. Overall, 10 removals, 13 gastric reductions, and 17 replacements were performed (40 total procedures). Of the 34 patients, 28 (82%) were available for follow-up. This group of 28 patients underwent 34 operative procedures (7 removals, 11 gastric reductions, and 16 replacements). No complications were associated with these 34 operations. Of the 11 patients with gastric reduction, 6 (55%) had subsequent recurrence of band slippage, resulting in 6 additional operations (5 replacements and 1 removal).
  
  
  CONCLUSIONS
  After band slippage, all 3 management options result in maintenance of most of the lost weight. However, because a large number of patients who undergo gastric reduction experience repeated slippage and require additional surgical intervention, gastric reduction should not be routinely performed in this population. Given the overall experience with revisional surgery after band slippage, additional investigation of the etiology of band slippage and its prevention is warranted.
