Event Description

According to the reporter, on laparoscopic vertical sleeve gastrectomy, during the first firing for sleeve creation, the doctor was unable to get the stapler in the right position as the patient was tight due to tummy tuck and tight falciform ligament.The surgeon used the reload to create some space, leveraging the stapler.At the time, the connecting joint of the reload and adapter was outside of the trocar.While the surgeon was creating the space with the reload, there was a slight snapping noise.The whole stapler was checked.The stapler screen was all green swim lane and was deemed normal.The first 60mm purple reload was then fired.The knife advanced all the way but then would not retract.Troubleshooting was performed and it was noticed that the connection joint at the reload and adapter had become loose.The manual retraction tool was tried but did not work.A new adapter was tried on but still would not work.This time, the adapter was stuck but was needed to be taken off the seal of the port as the competitor's trocar was removed to create more room to try and remove the reload.The surgeon broke the adapter off.The surgeon tried to use a right angle to physically drag the i-beam backward, but the device would not budge.The sales representative had consulted with the member service representative and the device hotline, but the issue could be resolved.The surgeon decided to cut the reload out of the stomach with mini shears.The stomach started bleeding, then the surgeon used a sealing device to seal the major vessels that were squirting blood.The surgeon then sutured the stomach to close it just enough to re-staple.A new set of handle, power shell, adapter, and reload were used to finish the sleeve.The sleeve was completed by starting the staple line just distal to the cut line created by removing the reload with mini shears.The procedure was extended for almost two hours due to the issue.The incision extended by not more than 1 inch (2.54cm).

Manufacturer Narrative

Evaluation summary: medtronic conducted an investigation based upon all information received.The device and a photo were available for evaluation.Visual inspection noted the reload was received clamped on tissue and the knife blade was fully advanced.The proximal end of the reload was noted to be heavily damaged.The reload adapter was broken off completely and the articulation flag was sheared.The reload cover tube was also damaged.It was reported that the reload did not complete its firing as the distal suture of the cartridge was not deployed.After the reload was fired, it was found that the connection joint at the reload and adapter had become loose.The reported issues were confirmed.The product analysis noted evidence that the device was not used as intended.The evaluation detected an unreported condition: there were broken reload adapter and bent articulation flag.The product analysis noted evidence that the device was not used as intended.The broken reload adapter may occur due to over flexure of the reload while attached to the instrument.While the bent articulation flag can occur if the loading unit is forcefully rotated while only partially inserted into the instrument shaft or if trying to remove loading unit without the reload being in neutral position.The manufacturing records for each device are thoroughly reviewed prior to release to ensure that it meets all medtronic quality specifications.The instructions included with this device provide the following guidance: do not attempt to insert or remove the instrument from the trocar sleeve if the instrument is in the articulated position.Medtronic is submitting this report to comply with fda reporting regulations under 21 cfr parts 4 and 803.This report is based upon information obtained by medtronic, which the company may not have been able to fully investigate or verify prior to the date the report was required by the fda.Medtronic has made reasonable efforts to obtain more complete information and has provided as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.In particular, this report does not constitute an admission by anyone that the product described in this report has any ¿defects¿ or has ¿malfunctioned¿.These words are included in the fda 3500a form and are fixed items for selection created by the fda to categorize the type of event solely for the purpose of regulatory reporting.Medtronic objects to the use of these words and others like them because of the lack of definition and the connotations implied by these terms.This statement should be included with any information or report disclosed to the public under the freedom of information act.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.A good faith effort will be made to obtain the applicable information relevant to the report.If information is provided in the future, a supplemental report will be issued.
