Optimal identification of the intersegmental plane can be challenging during thoracoscopic anatomical segmentectomy for lung cancer. We describe a simple new method of infrared-fluorescence-enhanced thoracoscopy with selected injection of indocyanine green into the bronchi not targeted for resection, which allows us to clearly identify the intersegmental plane in thoracoscopic segmentectomy.

We used the powered vascular staple (PVS) instead of the conventional staple technique [the utilization of the powered linier cutter (PLC)] or ligation for total 23 segmental or subsegmental bronchi with less than 10 mm in the bronchial luminal size on computed tomography (CT) in thoracoscopic segmentectomy. Our results suggested that the availability of the PVS represents a novel advance in the armamentarium and may have a possibility of being pervasive widely however, more observative periods and further sample accumulation are needed...

BACKGROUND: Compared to the pulmonary lobe, the anatomical structure of the pulmonary segment is relatively complex and prone to variation, thus the risk and difficulty of segmentectomy is increased. We compared three-dimensional computed tomography bronchography and angiography (3D-CTBA) combined with 3D video-assisted thoracic surgery (3D-VATS) to perform segmentectomy to conventional two-dimensional (2D)-VATS for the treatment of non-small cell lung cancer (NSCLC). METHODS: We retrospectively reviewed the data of randomly selected patients who underwent 3D-CTBA combined with 3D-VATS (3D-CTBA-VATS) or 2D-VATS at the Department of Thoracic Surgery, The First Affiliated Hospital of Soochow University Hospital, from January 2014 to May 2017...

OBJECTIVE: We describe laparoscopic transdiaphragmatic (LTD) chest surgery without intercostal incisions and focus on technique and safety. The goal of LTD is to minimize postoperative pain. METHODS: We reviewed all patients undergoing LTD chest surgery (September 8, 2010-April 4, 2017). We place 4 abdominal ports with the patient in semilateral decubitus, make 2 diaphragmatic openings, and advance 2 ports into the chest. The intrathoracic operation is standard video-assisted thoracoscopic surgery (VATS), and diaphragmatic openings are closed at the end...

A ground-glass opacity (GGO) lesion was discovered in a 64-year-old female 1 year ago. One month before administration, a follow-up CT showed the lesion in the apical segment of left upper lobe had increased from 8 to 11 mm in diameter. The lesion was diagnosed to be cT1aN0M0 non-small cell lung cancer (NSCLC) and a 3-port video-assisted thoracic surgery (VATS) anatomic segmentectomy was performed. Intraoperative frozen sections revealed a microinvasive adenocarcinoma. Systematic lymph node dissection was then carried out...

BACKGROUND: Accurate measurement of outcomes is essential to monitor the effectiveness of public health policies. In Italy, the Ministry of Health has chosen 30-day mortality after major surgical or medical procedures as the main outcome measure, pooling all pulmonary resections for malignancy in a single category. The present audit evaluated all pulmonary resections performed over a 13-year period in a single institution to assess the immediate (30-day mortality) and long-term (5-year survival) outcomes according to type and stage of disease and extent of surgery...

Pulmonary metastasectomy has become a standard procedure for pediatric patients with certain types of solid tumors. Surgeons, expert pediatric oncologists and radiation oncologists contribute with their different skills to the management of pulmonary metastases. Patients are usually scheduled for surgery in case of primary tumor control, in absence of metastases in other organs and when a complete resection is achievable. Nodules are removed through precision resections using electrocautery or laser methods in order to ensure radical surgery with adequate margins...

BACKGROUND: Pulmonary segmentectomy can be an oncologic equivalent of lobectomy for small non-small cell lung cancer. Uniportal video-assisted thoracoscopic surgery (VATS) has recently showed favorable surgical outcomes, but remains technical demanding, especially in a complex procedure like anatomic segmentectomy. This manuscript demonstrates the surgical techniques for uniportal VATS segmentectomies with the assistance of additional needlescopic instruments. METHODS: Data of 22 consecutive patients who underwent 24 needlescopic-assisted uniportal VATS segmentectomies between December 2016 and June 2017 was analyzed...

Over the past 20 years, there have been significant advancements in thoracoscopic surgical techniques as well as in lung cancer screening protocols, which have identified greater numbers of smaller lung tumors (<2 cm) that are more frequently operable and curable. These advancements have led to new interest in the thoracoscopic (VATS) approach to segmentectomy. This article will discuss the outcomes and technical considerations associated with VATS segmentectomy.

Nonintubated procedures have widely developed during the last years, thus nowadays major anatomical resections are performed in spontaneously breathing patients in some centers. In an attempt for combining less invasive surgical approaches with less aggressive anesthesia, nonintubated uniportal video-assisted thoracic surgery (VATS) lobectomies and segmentectomies have been proved feasible and safe, but there are no comparative trials and the evidence is still poor. A program in nonintubated uniportal major surgery should be started in highly experienced units, overcoming first a learning period performing minor procedures and a training program for the management of potential crisis situations when operating on these patients...

Unusual anatomical segmentectomies are technically demanding procedures that require a deep knowledge of intralobar anatomy and surgical skill. In the other hand, these procedures preserve more normal lung parenchyma for lesions located in specific anatomical segments, and are indicated for benign lesions, metastasis and also early stage adenocarcinomas without nodal involvement. A 32-year-old woman was diagnosed of a benign pneumocytoma in the anterior segment of the left-lower lobe (S8, LLL), so we performed a single-incision video-assisted thoracoscopic surgery (SI-VATS) anatomical S8 segmentectomy in 140 minutes under intercostal block...

Intersegmental demarcation line on the surface of the visceral pleura could not be found at thoracoscopic findings. The resected segments inflation (RSI) method has been reported as a useful technique for visualizing the intersegmental demarcation line during segmentectomy. Thoracoscopic anatomic segmentectomy is performed as follows: firstly, the pulmonary vein and artery of the segment planned for resection are dissected from the hilum in order to isolate the segmental bronchus located behind the pulmonary artery...

Nowadays, sublobar anatomic resections are gaining momentum as a valid alternative for early stage lung cancer. Despite being technically demanding, anatomic segmentectomies can be performed by uniportal video-assisted thoracic surgery (VATS) approach to combine the benefits of minimally invasiveness with the maximum lung sparing. This procedure can be even more complex if a combined resection of multiple segments from different lobes has to be done. Here we report five cases of combined and unusual segmentectomies done by the same experienced surgeon in high volume institutions to show uniportal VATS is a feasible approach for these complex resections and to share an excellent educational resource...

In segmentectomy using video-assisted thoracic surgery (VATS), surgeons view the operative field on a 2-dimensional video monitor. The lack of ability to palpate organs directly frequently leads to difficulties in evaluating anatomic relations. Three-dimensional computed tomography angiography and bronchography (3D-CTAB) using a virtual 3D safety margin enables thoracic surgeons to recognize the distance and positional relation between the primary tumor and intersegmental veins. It also helps with surgical planning, allowing the surgeon to secure an adequate safety margin around the primary tumor...

BACKGROUND: To evaluate the feasibility and efficacy of thoracoscopic anatomical segmentectomy (TS-S) using three-dimensional computed tomography (3D-CT) reconstruction and indocyanine green-fluorescence (ICGF) navigation. METHODS: Twenty TS-S procedures were performed for 15 primary lung cancers and 5 metastatic lung tumors. Preoperatively we evaluated the target segmental pulmonary artery and created a virtual intersegmental plane using 3D-CT reconstruction. Intraoperatively, the target segmental artery and bronchus were divided, and after intravenous systemic injection of indocyanine green (ICG, 0...

BACKGROUND: Despite the increasing demand for thoracoscopic lung segmentectomy, the appropriate training method is not well established. Therefore, we developed a swine model for anatomical thoracoscopic lung segmentectomy training. METHODS: Three-month-old pigs, weighing 40 to 45 kg, were used in this model. Anterior segmentectomy of the left cranial lobe and segmentectomy of the most anterior left caudal lobe were performed under general anesthesia and differential ventilation...

Worldwide accepted indications of anatomical segmentectomies are mainly early stage primary adenocarcinomas, pulmonary metastasis and benign conditions. Their performance through uniportal VATS has become more and more popular due to the less invasiveness of the whole procedure under this approach. Recently, many efforts have focused on non-intubated spontaneously breathing management of lobectomies and anatomical segmentectomies, although specific selection criteria and main advantages are not completely standardized...

Segmentectomy was first done in 1939 by Churchill and Belsey in 1939. Video-assisted thoracoscopic surgery (VATS) segmentectomies are still more technically challenging than VATS lobectomies. With the increasing rate of early stage lung carcinomas, the thoracoscopic segmentectomies may have a major role in a near future. Four anatomical VATS segmentectomy videos clips were shared in this study. CT three-dimensional reformation could exactly show the small pulmonary nodule's precise position, clarifies the surrounding structures' relationship like the pulmonary artery (PA), pulmonary vein (PV), bronchus (B), fissure, and lymph nodes...
