A rare complication after laparoscopic gastric banding: connecting-tube penetration into the hilus of the kidney.

Laparoscopic adjustable gastric banding is a common operation for morbid obesity. Late complications mainly originate from either the injection port (dislocation, infection, leakage) or the gastric band (pouch dilatation, slippage, leakage, gastric erosion). Complications from the tube, connecting the port with the band, are rarely described. We report the penetration of a loose connecting tube into the kidney 8 months after removal of an infected injection port.
