Sarcoidosis after adjustable silicone gastric banding - a report of two cases in Germany.

We report 2 patients who developed sarcoidosis after the implantation of adjustable silicone gastric banding (GB) in Germany. Before implantation, no pulmonary diseases were evident in the medical history of either patient. The 1st patient suffered sarcoidosis 12 months after GB. He has been treated at a hospital specialising in pulmonary diseases. Because of the treatment with corticoids, the patient has regained weight after the initial weight reduction. The 2nd patient developed signs of pulmonary infection on the 7th postoperative day (after GB). Pulmonary sarcoidosis was diagnosed 4 months later after consultation with a pulmonologist.
