Comparison between the AEON™ Endostapler and the Echelon FLEX™ Powered plus Stapler regarding lung tissue closure density after surgical removal of lung segments in severe pulmonary emphysema: A prospective, randomized, single-blind, monocentric study
Summary description of the study
In our research project, we aim to find out whether lung tissue is better sealed with a mechanically operated or a motor-driven stapler. The quality of the lung closure will be measured by whether there are leaks at the lung surface after the operation, leading to air escape and the formation of so-called "fistulas".
(BASEC)
Intervention under investigation
We do not yet know whether, after lung surgery in the presence of severe pulmonary emphysema, lung tissue can be better sealed with a manually operated or a motor-driven stapler. Numerous staplers are available on the market that are routinely used worldwide. These devices come in two versions: motor-driven or manually operated. It is currently assumed that motor-driven staplers seal lung tissue better than traditional manually operated staplers. With the manually operated AEONTM, it is now possible to reduce tissue tension during lung closure by adjusting tissue thickness, thereby minimizing lung tissue injury, which could ultimately lead to a reduction in air leaks. We want to find out which of the two methods can reduce both the duration and the volume of air escape at the lung closure site. The quality of lung tissue closure will be measured by whether there are leaks at the lung surface after the operation, leading to the formation of so-called "fistulas". If you participate and a bilateral surgical removal of lung segments is planned, the side that has been pre-selected as the starting side for the operation will be randomly closed either with the manually operated AEONTM stapler or with the motor-driven Echelon FlexTM stapler. The closure of the other side will automatically be performed with the other device. If only a unilateral lung operation is necessary, the lung tissue will be randomly closed either with the manually operated AEONTM or with the motor-driven Echelon FlexTM stapler. The two medical staplers used in this study, the AeonTM Endostapler and the Echelon FlexTM powered stapler, are approved medical devices routinely used in hospitals worldwide for sealing operated tissue.

Disease under investigation
You are recommended to undergo surgical removal of lung segments. You suffer from severe pulmonary emphysema. In severe pulmonary emphysema, leaks at the lung suture site often occur after surgery, allowing air to escape (fistulation). There are numerous staplers available on the market that are routinely used for sealing lung tissue. These devices come in two versions: manually operated or motor-driven.
