Olympus medical systems corp.
(omsc) was informed by the nurse that during an endoscopic mucosal resection using the subject device, the doctor used the yellow pedal, which omsc estimated that is the switch of vio3 erbe, to take off a polyp.
The patient jerked immediately and said she felt like an electric shock.
The doctor finished cutting off the polyp.
Then, they changed the snare from 15mm to a 10mm olympus snare because they took off another polyp.
The nurse thought that the snares might be at fault.
The engineer from erbe came the next day after the incident and found no fault with the machine.
The patient was re-admitted after the procedure due to a post polypectomy bleeding, but the nurse said it was not due to this incident as the patient had a lot of polyps removed.
