Abstract

Background: Video-Assisted Thoracic Surgery can be performed with the lung collapsed. During the procedure, pleural adhesion may result in lung injury, bleeding, and thoracotomy conversion. Identifying the presence of pleural adhesion before surgery can make it easy to plan trocar introduction and perform the procedure. Material and Method: Between June 2009 and November 2009, we performed ultrasound in 24 patients to detect pleural adhesion before surgery and compared the results with the operative findings. We primarily examined the lateral chest, where the trocar would be inserted, and, occasionally, the anterior or posterior chest. Result: Patient diseases were: 6 hyperhidroses, 8 interstitial lung diseases, 5 lung cancers, 2 mediastinal tumors, 1 peripheral pulmonary embolism, 1 metastatic lung cancer, and 1 sarcoidosis. Of the 22 patients who did not have pleural adhesions on ultrasound, four revealed mild adhesions not related to the trocar insertion sites. However, ultrasound showed pleural adhesions in two patients, consistent with the operative findings. There was no air leak or thoracotomy conversion related with trocar insertion. Conclusion: Ultrasound requires only a few minutes to detect the presence of the pleural adhesion and was very useful in identifying the pleural adhesion before VATS.

배경: 비디오흉강경수술은 폐를 허탈시켜 흉강내의 공간을 확보함으로써 시행되는데 흉막유착은 이러한 공간을 확보하는데 커다란 장애요인이 되어 폐손상 및 출혈을 유발할 수 있으며, 개흉술로 전환하는 원인이 되기도 한다. 흉강경수술을 시행하기 전에 흉막유착 유무를 확인하면 투관침의 위치선정 및 삽입방법을 포함한 수술과정을 계획하는데 매우 유용한 정보를 얻을 수 있다. 대상 및 방법: 2009년 6월부터 2009년 11월까지 비디오흉강경수술을 시행한 24명의 환자에서 수술 전에 흉막유착을 확인하기 위하여 초음파검사를 시행하고 흉강경수술시의 소견과 비교하였다. 검사부위는 투관침 삽입부위인 전액와선에서 후액와선까지의 흉부 측면을 주로 검사하였으며, 경우에 따라서는 흉부 전면이나 후면을 관찰하기도 하였다. 결과: 환자는 다한증 6예, 간질성폐병변 8예, 폐종양 5예, 종격동종양 2예, 말초폐동맥색전증 1예, 전이성폐종양 1예, Sarcoidosis 1예로 구성되었다. 초음파검사를 통해 흉막유착이 없다고 진단한 22예 중 4예는 검사부위와 동떨어진 곳에 일부 국한되어 경미한 유착이 있었으나 투관침 삽입부위와는 관련이 없었다. 흉막유착이 있다고 진단한 2예는 수술시 동일한 소견이었다. 수술중 투관침 삽입으로 인한 폐손상은 없었으며 개흉으로의 전환도 없었다. 결론: 초음파검사는 짧은 시간내에 검사가 이루어지며, 비디오흉강경수술을 계획하고 시행하는데 초음파를 이용한 흉막유착 여부의 확인은 매우 유익한 시술법이라고 사료된다.
