Event Description
The olympus representative reported on behalf of the customer, during the endoscopic retrograde cholangiopancreatography (ercp), the single use distal cover fell off the duodenovideoscope inside the patient and migrated distally.The user performed forward-viewing endoscopy to retrieve the cap but could not find it.They tried to locate it by fluoroscopy but the cap was not radiopaque and there are no radiopaque markers on it.The patient was admitted, and the next morning the patient passed the cap in their stool which was retrieved and not damaged.Afterwards the customer did an experiment and kept the cap in the abdomen of another patient who was undergoing a computerized tomography (ct) scan and abdominal x-ray, and the cap was not visible on either ct scan nor the x-ray.The customer noted that the cap is for single use but they can be removed intact very easily, and in their country due to financial constraints, these caps are reused multiple times and is one of the main reasons for the dislodgement of the caps during the procedure.The distal cover in this procedure was a reused one.The caps are difficult to locate when they fall off inside the patient as they are not visible on x-rays or ct scans.No patient harm was reported.The customer did not apply anti-fog agent to the scope lens.There were no chemicals used during the procedure that could adhere to the tip of the scope or distal cover.There was no damage on the distal cover when attached to the scope.The customer did not pull and twist the distal cover to make sure it did not come off.Related patient identifiers: (b)(6) single use distal cover (maj-2315/ sn: (b)(6)).(b)(6) duodenovideoscope (tjf-q170v / sn: (b)(6)).This medwatch is for (b)(6).
