The initial plan was to insert an endoscope - a long, flexible tube with a light and video camera attached to the end - to locate the device and extract it via the oesophagus.
But the procedure failed and the surgeons resorted to a laparotomy - where a large incision is made in the abdomen. The operation was successful and the phone, measuring 6.8 x 2.3 x 1.1cm, was sent for forensic examination due to the patient's incarceration status.
Four months later the man was reassessed with doctors reporting he had recovered well.
