It was reported that during a da vinci-assisted transthoracic chest anastomosis esophagectomy procedure, unformed staples resulted after firing a sureform 45 stapler instrument with a blue reload accessory.An inspection of the instrument revealed no damage or abnormalities.At the time of the issue, the surgeon was constructing a conduit using stomach tissue to reconstruct the esophagus.The clinical sales representative (csr) suggested that the problem may have resulted from crossing staple lines; however, the surgeon did not confirm this during discussions with the csr.To resolve the issue a backup stapler instrument was utilized, but it also resulted in unformed staples.Subsequently, the surgeon opted to use a third-party stapler instrument to complete the stapling, and the procedure was successfully completed without further complications.There was no bleeding or injury to the patient as a result of the issue.
