Accuracy of a 3-Dimensionally Printed Navigational Template for Localizing Small Pulmonary Nodules: A Noninferiority Randomized Clinical Trial.

Importance: Localization of small lung nodules are challenging because of the difficulty of nodule recognition during video-assisted thoracoscopic surgery. Using 3-dimensional (3-D) printing technology, a navigational template was recently created to assist percutaneous lung nodule localization; however, the efficacy and safety of this template have not yet been evaluated.

Objective: To assess the noninferiority of the efficacy and safety of a 3-D-printed navigational template guide for localizing small peripheral lung nodules.

Modified hook-wire placement technique for localizing multiple pulmonary nodules.

Background: The localization of multiple pulmonary nodules is challenging due to a high incidence of pneumothorax after each needle insertion into lung parenchyma. The aim of the current study is to verify the safety and effectiveness of a modified technique utilizing simultaneous Hookwire placement to localize multiple lesions.

Methods: The proposed method comprises a row of metal wires, perpendicular insertion, simultaneous release of Hookwire, and a lateral position to modify a conventional localizing technique.

Video-assisted thoracic surgery is an optimal alternative to conventional thoracotomy for reoperations for ipsilateral pulmonary lesions.

Background: Ipsilateral pulmonary reoperation is empirically considered a contraindication of video-assisted thoracic surgery (VATS) because of intrapleural adhesion and the destruction of anatomical structures caused by previous surgery. The purpose of this study was to present our experience of the use of VATS for ipsilateral reoperations.

Methods: The medical records of patients who underwent VATS reoperation or re-thoracotomy between January 2006 and March 2017 were retrospectively reviewed.

Risk Factors of Recurrence in Patients With Clinical Stage IA Adenocarcinoma Presented as Ground-Glass Nodule.

Background: In this study we aimed to identify the risk factors of recurrence in patients with clinical stage IA adenocarcinoma presented as ground glass nodule (GGN) on computed tomography scans.

Patients And Methods: The study included 245 patients with clinical stage IA adenocarcinoma presented as GGN who underwent surgery during 2010 to 2013. All patients were divided into 2 subgroups on the basis of consolidation diameter to tumor diameter (C/T) ratio on lung window: (1) ground-glass opacity (GGO)-dominant subgroup (C/T ≤ 0.

New horizons in surgical treatment of ground-glass nodules of the lung: experience and controversies.

Ground-glass nodule (GGN) is defined as a nodular shadow with ground-glass opacity that is generally associated with the early-stage lung adenocarcinoma. Nowadays, GGNs of the lung are increasingly detected with thin-section computed tomography scan. GGNs are categorized as pure GGNs and mixed GGNs according to the images from a high-resolution computed tomography.

[Application of Digital Drainage System in Postoperative Refractory Prolonged Air Leaks after Pulmonary Surgery].

Background: Postoperative prolonged air leaks is one of the most common complications secondary to pulmonary resections. Digital drainage system (DDS) is considered as an accurate and objective device which has been found to be comfortable and well tolerated by patients, economical as well. The aim of this study is to explore the application of DDS in patients with postoperative refractory prolonged air leaks after pulmonary surgery.

Relationship of Lymph Node Micrometastasis and Micropapillary Component and Their Joint Influence on Prognosis of Patients With Stage I Lung Adenocarcinoma.

This study aimed to investigate the relationship between lymph node micrometastasis and histologic patterns of adenocarcinoma, with a particular focus on their joint effect on prognosis. We retrospectively reviewed 235 patients with stage I adenocarcinoma from January 2009 to December 2009. Lymph node micrometastasis was evaluated by immunohistochemical staining for cytokeratin (AE1/AE3) and thyroid transcription factor-1.

Remedial localization after dislodgement of primary mechanical localization in lung surgery.

Background: Unhooking or displacement of hookwire or microcoil due to technical failures is rather common. We aim to establish a new technique for remedial localization in the case of displacement or unhooking of primary mechanical localization during lung surgery.

Methods: From February 2014 to September 2015, 18 consecutive cases of intraoperative dislodgement during video-assisted thoracoscopic surgery (VATS) were enrolled.

Tumor Spread through Air Spaces Affects the Recurrence and Overall Survival in Patients with Lung Adenocarcinoma >2 to 3 cm.

Objectives: Tumor spread through air spaces (STAS) is a novel invasive pattern in lung adenocarcinoma (ADC). The effects of the combination of STAS and tumor size on survival have not been well studied.

Methods: A total of 383 patients with ADC 3 cm or smaller (stage IA) and 161 patients with stage IB ADC were identified from 2009 to 2010.
