BACKGROUND: Endoscopic devices often cause device-related surgical morbidities such as postoperative bleeding. Delayed bleeding due to a protruding edge of an endostapler has not been previously described in the literature.
CASE PRESENTATION: An 80-yr-old man with a second primary lung cancer underwent a wedge resection of the right lower lobe. He developed sudden hypotension and massive bleeding from the chest tube 4 h after the surgery and underwent an emergency reoperation. A torn parietal pleura was found to have caused a persistent bleeding. There was a sharp protruding edge created by multiple firings of the endostapler. The subsequent lung expansion would have promoted a direct contact between the edge and parietal pleura resulting in delayed bleeding.
CONCLUSIONS: A protruding edge due to multiple firings of an endostapler could injure the parietal pleura and cause delayed bleeding after a lung resection. This type of injury would be more common in wedge resection cases because of the larger residual lung volume preserved, which is expected to have a better lung expansion and facilitate the direct contact of the staple line and parietal pleura.
