The device was returned to the manufacturer and an evaluation was conducted.A visual inspection was performed on the device with the use of a microscope.It was noted that the bending section cover glue was bumpy and lifted.The device was rough to the touch when tactile force was applied.The bumpy/lifted bending section cover glue was most likely what the patient was experiencing.There was evidence of scratch mark streaks on the bending section cover glue.Additionally, the bending section cover was noted to be stretched causing it to overlap with the distal end tip.The fiber scope was further checked with no evidence of tears.The scope also passed the leak test.The instruction manual warns the user: never operate the bending section, perform suction, insert or withdraw the endoscope¿s insertion tube without viewing the endoscopic image.Patient injury can result.Do not twist or bend the bending section by hands.Equipment damage may result.Do not squeeze the bending section forcefully.The covering of the bending section may stretch or break and cause water leaks.Based on the evaluation the cause of the bumpy/lifted glue was most likely due to mishandling.
