肺癌に対する胸腔鏡手術創部に発生した肺ヘルニア

Lung Hernia at the Port Site After Thoracoscopic Resection for Lung Cancer

肺ヘルニアは肺実質が正常な胸腔内区域を越えて突出するまれな疾患であるが，近年では低侵襲心臓手術や胸腔鏡補助下手術（VATS）などの小さい手術創部に発生した報告例がみられる1～5）．われわれはVATS肺部分切除術後の創部に発生し，胸腔鏡下に代用物補塡法で修復した肺ヘルニアの1例を経験したので文献的考察を加え報告する．

A lung hernia is a rare condition in which the lung parenchyma protrudes beyond its normal thoracic cavity boundaries. Traditionally, lung hernias have been associated with chest trauma or congenital weakness of the chest wall. However, in recent years, there have been increasing reports of lung hernias developing at small surgical wound sites, such as those created by minimally invasive cardiac surgery or thoracoscopic procedures. Here, we present a case of a lung hernia that occurred at the port site following a thoracoscopic partial lung resection. The hernia was successfully repaired using a thoracoscopic approach with prosthetic reinforcement. We also discuss relevant literature on the etiology, diagnosis, and treatment of port-site lung hernias, highlighting the importance of careful surgical technique and appropriate wound closure to prevent this rare but significant complication.
