During a dilation procedure, the physician used a cook hercules 3 stage wireguided balloon esophageal-pyloric-colonic.After advancing a wire guide through the target site, the device was advanced over the wire guide for dilation of the digestive tract.However, because the stenosis was so severe, the shaft [catheter] became bent while the user was advancing the device and inflating the balloon several times; then, a hole was created in the bent point [catheter breakage].Water inside the balloon started leaking from the hole, so the device was replaced with another balloon, and the procedure was completed with the replacement device.There have been no adverse effects to the patient reported.A section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.
