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. Keywords Gastric banding . Complication . Tubing . Migration Case ReportA 46-year-old obese female patient presented herself with pain in the left side of her abdomen and back. Her medical history consisted of diabetes, hypercholesterolemia, appendectomy, and laparoscopic cholecystectomy. She had a laparoscopic adjustable gastric banding (LAGB) placement 1.5 years prior to presentation. This procedure was complicated after 10 months by dislocation of the reservoir, which was surgically refixed. Eight months before presentation, she developed an infection at the site of the reservoir necessitating removal of the reservoir and leaving the gastric band and tubing intraabdominal.At presentation, the patients' pain was not related to movement, respiration, or oral intake. Her weight loss was 18 kg in the last year despite removal of the reservoir. She also complained of pyrosis. Physical examination showed a cicatrical hernia in the left upper quadrant. There were no further abnormalities. Her BMI was 33.9. Laboratory test showed a BSE of 71 mm/h, white cell count of 7.0×10 9 /L, and CRP of 12 mg/L.
