The use of endostaplers during thoracoscopic pulmonary resections has been a common procedure for respiratory surgeons. In Japan, we can choose 2 different types of staplers from 2 companies, namely, Tyco Healthcare Japan and Johnson & Johnson company. The staplers from each company show different characteristics. Therefore, we should choose which stapler to use by each character equipped. Each stapler has differences in compatibilities of cartridges, in sizes and in weights. Some adverse events or incidents were attributable to surgical or technical errors; many of them might be linked to the device. This manuscript aims to explain the differences and advantages in each stapler and to help to choose which stapler is suitable. However, we have to do surgery taking malfunctions of devices into consideration at all times.
