Key Points

This research aims to evaluate the incidence and surgical management of pneumothorax caused by elongated pulmonary cysts in the azygoesophageal recess.
Retrospective analysis of 4 surgical cases from 2020-2025
Surgical intervention focused on achieving air leak cessation without resection of the bulla
No recurrence was noted post-surgery.
All 4 cases successfully treated with no recurrence of pneumothorax observed post-intervention.
Surgical innovation was necessary due to the complex anatomy of the azygoesophageal recess and its limited working space.

Abstract

奇静脈食道陥凹（azygoesophageal recess：AER）にできる気腫性肺囊胞は，傍脊柱へちま型ブラ（へちま型ブラ）と称され，肺気腫患者では気胸の原因として重要性が報告されている．このAERは肺門部後方で術中に見落としやすくワーキングスペースの少ない領域であり，手術時に工夫が必要である．当院で2020年からの5年間に4例のへちま型ブラによる気胸に対して手術を行った．自動縫合器によるブラ切除は行わず，気漏停止を目的とした手術で再発を認めていない．肺気腫を有する気胸ではAERに注目すること，手術の工夫が必要であることを認識するべきである．
