No root cause could be determined because the device was not available for evaluation.Justright surgical spoke with the surgeon regarding the initial surgery.The doctor indicated that he was unsure if he held the jaws shut for 30 seconds before firing the stapler.However, he inspected the staple line intra-operatively and believed all staples were fully formed.He also indicated that he might have tried to separate the wisp of tissue left at the end of the staple line by pulling with the stapler, instead of cutting it.That action may result in a pulled/open staple at the end of the staple line.Subsequent discussion with the surgeon during follow-up indicated that the bowel obstruction was caused by a mesentery stricture due to a staple that "snagged" on a piece of mesentery.
