band erosion
Migration of gastric band through the stomach wall, a serious late complication of adjustable banding.
Full Definition
Band erosion is a serious late complication of laparoscopic adjustable gastric banding where the silicone band gradually migrates through the gastric wall into the stomach lumen. This erosion process typically occurs months to years after initial surgery and may present with loss of restriction, inability to adjust the band, abdominal pain, or infection. The exact etiology is unclear but may involve pressure necrosis, foreign body reaction, or bacterial biofilm formation. Treatment requires complete band removal and may necessitate conversion to an alternative bariatric procedure.
Usage
Usage note: Distinct from band slippage, which involves external displacement.
