“…Segmentectomy was categorized into simple or complex from the standpoint of technical aspect: resection of superior segment of the lower lobe or the lingular segment was de ned as simple. Complex segmentectomy was resection of segment other than that to be resected in the simple segmentectomy, beside, complex segmentectomy was de ned as resection of a segment that had more than one intersegmental plane (7).…”

Abstract Objective To investigate whether video-assisted thoracoscopic segmentectomy using near-infrared fluorescence imaging had better intersegmental plane visualization and peri-operative outcome in patients with chronic lung diseases. Methods Data were collected retrospectively from March 2014 and August 2019. A total of 92 patients with pulmonary nodules underwent near-infrared fluorescence guided uni-port thoracoscopic segmentectomy(NIF-VATS), 149 patients underwent thoracoscopic segmentectomy with inflation-deflation method(ID-VATS). After 1:1 propensity matching, perioperative outcomes between NIF-VATS and ID-VATS was compared. Results Incision size was 3 cm in both group.Mean operative time was 79 minutes in NIF-VATS group and 96 minutes in ID-VATS group. The intersegmental plane was not clear in 33 cases of ID-VATS group, and no clear boundary was found after prolonged waiting time. Emphysema or pulmonary bullae could be found in chest CT scan in these patients, they all were diagnosed as chronic obstructive pulmonary disease. In NIF-VATS group, the intersegmental plane was not clear in 8 cases. Under the guidance of three-dimensional reconstruction and preoperative positioning, the oncological margin length of both groups met the requirements of surgical quality control. The intraoperative blood loss, number of lymph node resection, showed no statistical difference between the two groups. Postoperative air leakage was more often observed in ID-VATS group. The postoperative drainage duration, postoperative hospitalization time was shorter in ID-VATS group. Conclusions Compared with inflation-deflation method, segmentectomy using NIF imaging is feasible for patients with chronic lung diseases with better intersegmental plane, shorter operation time, less complications, it might lead to faster recovery.

“…In addition to the increasing frequency of sublobar resection of GGO-dominant tumors, studies have been conducted to demonstrate the e cacy of sublobar resection for solid-dominant tumors of 2 cm or less. Two important randomized controlled trials (JCOG0802 and CALGB140503) of sublobar resection for solid-dominant tumors are being conducted and will produce results in a few years [6][7][8]. The results of these studies will clearly demonstrate the e cacy of sublobar resection in small solid-dominant lung cancer.…”

Background. Sublobar resection is sometimes performed as a surgical treatment for small peripheral tumors. However, there is a question about whether sublobar resection is adequate treatment when visceral pleural invasion is diagnosed postoperatively. The purpose of this study was to evaluate the prognosis of patients with small-sized stage IB non–small cell lung cancer (NSCLC) after sublobar resection.Methods. From January 2010 to December 2018, 227 consecutive patients with eighth edition TNM stage IB NSCLC (per the joint staging system of the International Association for the Study of Lung Cancer and the American Joint Committee on Cancer) underwent curative surgery. The clinicopathological characteristics and prognosis were compared between the sublobar resection group and the lobectomy group. The sublobar resection group included only small-sized (invasive component size ≤ 2 cm) NSCLC.Results. In all study patients, clinicopathological characteristics between the sublobar resection and lobectomy groups were not different except in maximum standardized uptake value and invasive component size. The 5-year recurrence-free survival rate was 80.7% after sublobar resection and 73.4% after lobectomy (P = .349). The 5-year overall survival rate was 87.3% after sublobar resection and 84.8% after lobectomy (P = .503). In patients with small-sized NSCLC, the clinicopathological characteristics were not different between the sublobar resection group and the lobectomy group. The 5-year recurrence-free survival rate was 80.7% after sublobar resection and 72.3% after lobectomy (P = .417). The 5-year overall survival rate was 87.3% after sublobar resection and 91.2% after lobectomy (P = .956). Sublobar resection was not a risk factor for recurrence in the multivariate analysis.Conclusions. The prognosis of sublobar resection in patients with small-sized stage IB NSCLC was comparable with lobectomy. Thus, additional completion lobectomy may not be essential in this setting, despite postoperative upstaging from T1 to T2a.

“…Although the optimal surgical treatment for lung cancer has long been lobectomy, segmentectomy may become a standard treatment for early-stage lung cancer. 1) Previous studies have shown that segmentectomy is oncologically comparable with lobectomy for early-stage lung cancer. 2) Segmentectomy also has the advantage of preservation of lung function.…”

Background:Pulmonary segmentectomy can be challenging when thoracic surgeons encounter anatomical anomalies. A displaced left apicoposterior bronchus is a rare bronchial anomalythatmakes lung anatomical resection challenging. We herein present a case of successful left apicoposterior segmentectomy for lung cancer in a patient with an anomalous segmental bronchus. Case presentation:A 70-year-old man was clinically diagnosed with early-stage lung cancer for which segmentectomy was indicated. A preoperative image revealed a displaced left apicoposterior bronchus that branched behind the left main pulmonary artery. With the aid of three-dimensional reconstruction imaging and systemic indocyanine green injection, we successfully performed left apicoposterior segmentectomy under complete video-assisted thoracic surgery. The pathological diagnosis was adenocarcinoma. The patient was alive without recurrence 8 months after segmentectomy.Conclusion:Preoperative three-dimensional imaging and systemic indocyanine green injection enabled us to successfully conduct challenging segmentectomyin a patient with an anomalous bronchus.
