A novel form of precise segmentectomy-Triumphal arch-like anatomical segmentectomy

The increasingly accurate sublobar anatomical resection is constantly being explored and practiced. Surgeons try to preserve as much viable lung tissue as possible. Sublobar resection of the target tissue is similar with a cone-shaped structure which penetrates deeply into the pulmonary parenchyma and runs through the lobe at both ends. This has not previously been described. The remaining lung tissue resembles the Triumphal Arch in Paris, France. Here, we describe triumphal arch-like sublobectomy in detail, aiming to provide clinicians with an idea to explore this novel sublobectomy under similar conditions.
