Background
A lack of clarity remains over the optimal strategy for the management of laparoscopic adjustable gastric band (LAGB) slippage, which, although rare (around 3% in our experience), can when acute result in obstruction, gastric erosion or ischaemia. Typically, slipped bands are removed acutely. The aim of this study was to explore outcomes following immediate or delayed resiting of slipped LAGBs in a single centre, comparing simple repositioning with retunnelling and replacement.
Methods
A retrospective analysis of computerised records, notes and prospectively maintained bariatric databases was undertaken to identify all patients with a slipped LAGB in a single centre.
Results
Thirty-two patients required operative intervention following a diagnosis of slipped LAGB (median time from initial LAGB insertion to slippage 2.9 years). Two (6%) patients underwent band removal and 30 (94%), band revision surgery (25 immediately and five at a planned but expedited procedure).Twenty-four (77%) patients underwent insertion of a new LAGB via a de novo retrogastric tunnel, five (21%) of which required further future operative intervention; whereas, six (23%) patients underwent repositioning of the existing LAGB within the same tunnel, five (83%) of which underwent further operative intervention (log-rank test p = 0.0001). Following LAGB revision, there was no significant further change in BMI (median + 1 kg/m2; range − 13 to + 10 kg/m2).
Conclusion
Resiting of slipped LAGBs is safe and maintains weight loss. Although a significant risk of future operative intervention remains, this can be reduced via the creation of a de novo retrogastric tunnel for band resiting.
