“…Segmentectomy has become a popular procedure; however, precise data on LS 4 segmentectomy are still limited (Nakazawa et al, 2022). One reason is that the size of the LS 4 segment is usually considered small and is often resected along with the other segments.…”

“…As a result, the “superior” lingular S 4 segment and “inferior” lingular S 5 segment can also be the “lateral” lingular S 4 segment and “medial” lingular S 5 segment, respectively, like their counterparts in the middle lobe (Figure 7). The size of the lingular segment varies significantly among the patients (Nakazawa et al, 2022). The data in our study may explain this.…”

The lingular segment bronchi usually bifurcate into superior lingular (B4) and inferior lingular (B5) segmental bronchi. We report 32 horizontally bifurcated lingular segment bronchi cases, analyzing the bronchovascular variations and the perioperative outcomes. All patients with pulmonary lesions underwent three‐dimensional computed tomography bronchography and angiography between January 2019 and January 2022. The bronchovascular patterns were analyzed for each patient. A consecutive 5280 patients were included, and 32 cases of this malformation were identified. The incidence of the lateral (B4) and medial (B5) lingular segmental bronchi is 0.6%. The A4 and A5 arise separately in 21 (65.6%) patients. In 9 (28.1%) patients, the A4a arises from the common trunk of A4 + 5. In 2 (6.3%) patients, the A4 arises from the interlobe artery, while A5 is a mediastinal lingular artery. The common trunk of V4a + b is found in 19 (59.4%) patients. The V5 is the least changeable of the segmental bronchi veins. Among the 32 patients, five patients had an LS4 segmentectomy. The surgical details of the five patients are summarized. The laterally and medially bifurcated lingular bronchus pattern is a rare anomaly. It implies that the lingular bronchus is not only superiorly and inferiorly bifurcated.

“…Data concerning lobectomy + segmentectomy are scarce. However, cases of lobectomy + segmentectomy will increase as segmentectomy gains more popularity, leading to more diverse procedures, including atypical segmentectomies, segmentectomy + segmentectomy, or lobectomy + segmentectomy, becoming part of a surgeon's armamentarium (2,(19)(20)(21)(22)(23). Summarily, lobectomy + segmentectomy is a lung-preserving procedure that can benefit patients with multiple or advanced diseases involving two lobes.…”

Background: Segmentectomy is a standard procedure, and there is considerable data on routine segmentectomies. However, there are only few reports on lobectomy performed in combination with segmentectomy (lobectomy + segmentectomy). Thus, we aimed to clarify the clinicopathological features and surgical outcomes of lobectomy + segmentectomy. Methods:We reviewed patients who underwent lobectomy + segmentectomy between January 2010 and
