Abstract

Background. Reduction of lung cancer lesions mainly based on ground-glass shadows makes it difficult to evaluate the resection margin if it is difficult to touch during surgery. Therefore, the resected specimen was inflated outside the body, and CT was performed to assess whether it was possible to confirm the presence of the tumor and measure the resection margin.

Case. 1) A 82-year-old female underwent partial resection of the right lung for suspected lung cancer in the lower right lobe S10. 2) A 70-year-old female underwent partial resection of the right lung for suspected lung cancer in the lower right lobe S9.

Method. Each excisional specimen after partial excision was punctured as thinly as possible with a thin needle as far as possible from the pleura distant from the tumor, and a syringe was used to inject air slowly and sufficiently. Then, a well-expanded resected specimen was placed in a closed container and taken into the CT room.

Results. By inflation of the resected specimen similar to that inside the body and performing CT, it was possible to confirm the resection of the unpalpable lesion and measure the excision margin by CT.

Conclusion. It was convenient and useful to confirm the existence of the tumor and evaluate the surgical margin without damaging the specimen by inflating the resected lung during the operation and performing CT evaluation for a palpable lesion.
