OBJECTIVES: Lobes occasionally displace after lobectomy, referred to as "lobar shifting". However, the benefits, especially in postoperative pulmonary function, remain controversial. This study aimed to measure the effect of lobar shifting on postoperative pulmonary function especially in the right upper lobe. METHODS: This retrospective study includes 273 right upper lobectomy patients (lobectomy group) and 24 right upper segmentectomy patients (segmentectomy group) from 2012 to 2021...

BACKGROUND: Robotic-assisted thoracic surgery (RATS) is a minimally invasive procedure; however, some patients experience persistent postoperative pain. This study aimed to investigate factors related to postoperative pain following RATS. METHODS: The data of 145 patients with lung cancer, who underwent RATS with a four-port (one in the sixth intercostal space [ICS] and three in the eighth ICS) lobectomy or segmentectomy between May 2019 and December 2022, were retrospectively analyzed...

BACKGROUND: Minimally invasive anatomical resection (AR) for posterosuperior lesions is technically challenging.1,2 The Glissonean approach or puncture technique is generally selected.3,4 The tumor-feeding portal pedicle compression AR (C-AR) is an established procedure in open surgery.5 This technique has benefited from the association with indocyanine green (ICG) fluorescence, used to enhance the anatomical area to be resected.6 Recently, C-AR via the minimal access approach has been reported...

BACKGROUND: Whether wedge resection is oncological suitable for ground glass opacity (GGO)-dominant non-small cell lung cancer (NSCLC) ≤2 cm is still debatable. The aim of this study is to investigate the short-term and long-term outcomes of intentional wedge resection and segmentectomy for those patients. MATERIALS AND METHODS: This was a real-world study from one of the largest thoracic surgery centers in XX. Patients who underwent intentional wedge resection or segmentectomy for ≤2 cm CTR(consolidation-to-tumor)≤0...

PURPOSE: We evaluated the surgical outcomes of salvage extended surgery after definitive medical treatment with an immune-checkpoint inhibitor (ICI) for locally advanced or unresectable non-small-cell lung cancer (NSCLC). METHODS: The subjects of this single-center retrospective analysis were 14 patients who underwent salvage surgery after ICI treatment between May, 2017 and April, 2023 at our institute. We reviewed the comprehensive surgical outcomes, including operative procedures, intraoperative findings, and postoperative morbidities...

A 71-year-old man had previously undergone S7 + S8 dorsal segmentectomy and S5 partial hepatectomy for hepatocellular carcinomas. Six months later, he experienced abdominal distention. Abdominal computed tomography (CT) showed massive ascites and a significant hepatic arterioportal shunt. The ascites was thought to be caused by portal hypertension due to a high-flow hepatic arterioportal fistula (HAPF). The fistula, located between the right hepatic artery A7 and the right portal vein, was embolized with microcoils under flow control using a balloon catheter...

BACKGROUND: The study purpose was to determine the optimal extent of lymph node dissection required in patients with small (≤ 3 cm) radiologically ground-glass opacity-dominant, peripheral, non-small cell lung cancer tumors. METHODS: We analyzed the clinicopathological findings/surgical outcomes of 988 patients with radiological, ground glass opacity-dominant non-small cell lung cancer without lymph node involvement who underwent complete resection of the primary tumor between 2010 and 2020...

BACKGROUND: Recently, segmentectomy has emerged as a viable treatment option for early-stage lung cancer. Segmentectomy can be divided into simple segmentectomy and complex segmentectomy. While simple segmentectomy is a relatively straightforward surgical procedure, complex segmentectomy poses a considerable challenge because of its intricate anatomical variations and the need for a complex surgical approach. The introduction of uniportal video-assisted thoracoscopic surgery (VATS) further complicates matters...

BACKGROUND AND OBJECTIVE: The adoption of robotic surgery for general thoracic surgery has rapidly progressed over the last two decades from its application in basic operations to complex pathologies. As such, the purpose of this narrative review is to highlight the collective experience of tackling complex thoracic surgical operations with minimally invasive robotic solutions. METHODS: Electronic searches of PubMed were conducted for each subtopic, using specific keywords and inclusion criteria...

BACKGROUND: Non-intubated thoracoscopic surgery with spontaneous breathing is rarely utilized, but may have several advantages over standard intubation, especially in those with significant cardiopulmonary comorbidities. In this study we evaluate the safety, feasibility, and 3-year survival of thoracoscopic surgery without endotracheal intubation for oncologic and non-oncologic indications. METHODS: All consecutive patients [2018-2022] selected for lung resection or other pleural space intervention under local anesthesia and sedation were compared to a cohort undergoing elective thoracoscopic procedures with endotracheal intubation...

BACKGROUND: Thoracic epidural analgesia (TEA) and liposomal bupivacaine (LB) are two methods used for postoperative pain control after thoracic surgery. Some studies have compared LB to standard bupivacaine. However, data comparing the outcomes of LB to TEA after minimally invasive lung resection is limited. Therefore, the objective of our study was to compare postoperative pain, opioid usage, and outcomes between patients who received TEA vs . LB. METHODS: We conducted a retrospective chart review of patients who underwent minimally invasive lung resections over an 8-month period...

BACKGROUND: The da Vinci single-port system (SPS) (Intuitive Surgical, Sunnyvale, CA, USA) was designed for single-port (SP) surgery. Although we have reported our clinical outcomes using the SPS for a simple procedure in general thoracic surgery, major pulmonary resection had been performed only in cadaveric experiments to date. This study evaluated the feasibility of SP subcostal robotic major pulmonary resection using the SPS. Here, we present our initial clinical experience of SP subcostal robotic major pulmonary resection at our institution...

BACKGROUND: We aimed to validate the prognostic implication of uncertain resection [R(un)] proposed by International Association for the Study of Lung Cancer (IASLC) and evaluate the prognostic value of spread through air spaces (STAS) in reclassifying R classification among patients with lung adenocarcinoma following segmentectomy. METHODS: We enrolled 1,007 patients who underwent segmentectomy for c-stage IA lung adenocarcinoma between 2014 and 2017. Recurrence-free survival (RFS) and overall survival (OS) were compared to evaluate the prognostic value of IASLC-R(un) and STAS...

INTRODUCTION: Spread through air spaces (STAS) is a novel pattern of invasion in primary lung cancers, which was introduced in the 2015 World Health Organization classification. Several studies have validated STAS to be a predictor of clinical outcome in lung adenocarcinoma. However, little is known about STAS as a mode of intraparenchymal diffusion of pulmonary metastases (PMs). OBJECTIVES: The aim of this study was to investigate the incidence of STAS among PMs and the association between STAS and clinicopathological characteristics of PMs...

OBJECTIVE: Segmentectomy and mediastinal lymph node dissection (LND) may increasingly be used for non-small cell lung cancer (NSCLC). Lymph node metastasis (LNM) distribution varies by lower lobe segments; however, its segment-specific spread to the lower zone (#8, 9) (LZ) in lower lobe NSCLC is seldom reported. METHODS: In total, 352 patients with clinical T1 lower lobe NSCLC who underwent lobectomy with systematic or lobe-specific LND were included for analysis between January 2006 and December 2018...

BACKGROUND: Video-assisted thoracoscopic segmentectomies have become the gold standard for the treatment of early-stage non-small cell lung cancer less than two centimeters. The main difficulty is the identification of intersegmental boundary lines which dictate postoperative morbidities. METHODS: We conducted a retrospective study to compare the perioperative outcomes of patients who underwent minimally invasive segmentectomy using the traditional deflation-inflation method or the novel indocyanine green (ICG) technique...

BACKGROUND: This study compares sublobar resections - wedge resection and segmentectomy - in clinical stage IA lung cancers. It tests the hypothesis that overall survival post-wedge resection is similar to segmentectomy. METHODS: Adults undergoing wedge resection or segmentectomy for clinical stage IA lung cancer were identified from the STS-General Thoracic Surgery Database. Eligible patients were linked to the Centers for Medicare & Medicaid Services database using a matching algorithm...

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms constituting less than 2% of all soft tissue tumors. They typically originate in the thoracic cavity, mainly in the pleura, but can also occur in other various sites such as lung parenchyma, pericardium, and bronchus. In this study, a 49-year-old non-smoking female with a history of allergies presented to our pulmonary clinic with a chronic cough. An explorative bronchoscopy revealed an intrabronchial mass in the left superior bronchi, and a 68 Ga-DOTATOC positron emission computed tomography suggested a carcinoid tumor...

PURPOSE: To assess the safety and effectiveness of using modified radiation lobectomy (mRL) to treat primary hepatic tumors located in the right hepatic lobe (segments V-VIII) and determine future liver remnant (FLR) hypertrophy. METHODS: A retrospective review was performed at a single institution to include 19 consecutive patients (7 Female, 12 Male) who underwent single-session mRL for right sided primary hepatic tumors: 15 received segmentectomy plus lobectomy (segmental dose >190 Gy and lobar dose >80 Gy); 4 were treated with the double-segmental approach (dominant segments >190 Gy and non-dominant segments > 80 Gy)...
