Thoracoscopic fissure plane–preserving combined segmentectomy of subsuperior and cranial subsegment of lateral basal segment

Abstract

Cranial subsegment of the lateral basal segment (S9a) and some subsuperior segments (S∗) are bordered by 4 intersegmental planes. Often, this resection uses an incision of the intersegmental border between S6 and S8 at the interlobar fissure.1,2 As the result of increasing cases of multiple metachronous lung cancer,3 the chance for future operations for such patients should be considered. Thus, we are preserving the intersegmental plane between S6 and S8 and minimizing the exposure of the lung parenchymal raw surface to decrease future adhesions.
