Laparoscopic adjustable gastric banding migration: an early approach for a late complication.

AIM: Laparoscopic adjustable gastric banding (LAGB) migration is an uncommon late complication after bariatric surgery. It usually presents with an unexplained weight increase or without any symptom. Current guidelines do not establish the timing of a clear endoscopic follow-up to prevent and/or to treat this kind of complication.

PATIENTS AND METHODS: Long-term follow-up was performed in 217 patients with LAGB (37 underwent surgery in other bariatric centers). At the endoscopic check, 3 patients presented banding erosion respectively 7, 9 and 11 years after surgery. In all three cases the patients, lost at the follow-up in their bariatric centers, had weight gain. During the endoscopy was treated just one patient because of the advanced migration. For the other patients, with a minimal migration, the choice was to perform an endoscopic surveillance every 4 months.

DISCUSSION: Removal of eroded gastric banding with common endoscopic devices is feasible, safe, and effective.

CONCLUSION: With our experience we suggest to perform planned endoscopy at least within 2 years in order to guarantee the early diagnosis and managing of gastric banding erosion.
