マイクロ波凝固と高周波スネアを用いて気管支鏡下に切除した気管支内過誤腫の1例

Endobronchial Hamartoma Treated with Bronchoscopic Microwave Tissue Coagulation and Electrosurgical Snaring：Report of a Case

はじめに　気管支内に発生する過誤腫は，事前に確定診断がつきにくいこともあり，従来は外科的切除の適応とされてきたが，近年では侵襲性の低さから気管支鏡下切除が選択されることが多くなってきている．

A 35-year-old man had chronic cough and was treated as asthma at local doctor. Since the symptoms was not improved, chest computed tomography （CT） was performed and an approximately 5 mm nodule with calcification was found in the left main bronchi. He was referred to our hospital for treatment. Bronchoscopic examination revealed a polypoid lesion in the membranous part of the left main bronchus. Since transbronchial biopsy revealed no malignant findings, bronchoscopic resection using microwave tissue coagulation and electrosurgical snaring was performed safely under the general anesthesia. The tumor was histologically diagnosed as endobronchial hamartoma.
