BACKGROUND: Our previous report suggested that fluorescence thoracoscopic anatomical segmentectomy (TAS) using intravenous (IV) indocyanine green (ICG) injection is safe, feasible, and efficacious for identifying segmental boundaries. However, contrast visualization in the conventional indocyanine green mode (CIM) remains relatively obscure in smoking-related comorbidities. Our aim was to evaluate the safety and efficacy of recently released Spectra-A with CIM by simultaneous observation...

There are many novel technologies that enable complex segmentectomy to be performed. As lung cancer screening becomes more prevalent, patients are increasingly diagnosed with early stage lung cancer, multifocal disease, and second primary tumors. This shift to an earlier clinical presentation combined with advances in technology and an emphasis on minimally invasive techniques have led to the current developments we are now seeing with anatomic segmentectomy. In this paper, we describe the operative technique of an indocyanine green (ICG)-guided video-assisted thoracoscopic surgery (VATS) single basilar segmental resection, augmented with methylene blue dye marker localization via SuperDimension electromagnetic navigational bronchoscopy...

INTRODUCTION: The indocyanine green-photodynamic eye (ICG-PDE) system is useful to detect small hypervascular liver tumors, hepatocellular carcinoma (HCC), on the liver surface. This system may be also applied to improve determining the location of metastasis or tumor thrombus (TT). We herein report three case reports. ICG was administered preoperatively for functional testing and images of the tumor were observed during hepatectomy using a PDE camera. CASE SERIES: The patient in case 1 exhibited advanced HCC with TT in the portal trunk...

In the era of lung cancer screening and early detection of lung lesions, pulmonary segmentectomy has gained wide acceptance between thoracic community reducing the need of lobectomy for diagnostic purpose and treatment in case of centrally located benign, multiple or undetermined lesions. In rigorously selected patients with stage I non-small cell lung cancer (NSCLC), segmentectomies seem to offer similar survival outcomes rather than lobectomies, but associated with a better conservation of lung function. However, segmentectomy is a more challenging procedure to be performed compared to lobectomy, especially by video-assisted thoracic surgery (VATS)...

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.

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...

Thoracoscopic S9-10 segmentectomy is more difficult than other segmentectomies because of the complexity of the peripheral pulmonary anatomies and the difficulty of dividing the intersegmental plane. In S9-10 segmentectomy, the intersegmental plane between segments S6 and S8 near the major fissure impedes division of the plane between segments S6 and S9-10, or S8 and S9-10. Dividing the intersegmental plane between segments S6 and S8 with stapling is difficult, because peripheral pulmonary anatomies are not exposed clearly...

OBJECTIVES: Segmentectomy by video-assisted thoracoscopic surgery (VATS) permits anatomical resection for diagnosis and treatment of small lung nodules but requires that intersegmental planes and segmental vessels be identified accurately. Near-infrared angiography with systemic injection of indocyanine green (ICG) can precisely identify the intersegmental plane. The purpose of this study was to confirm the usefulness of ICG angiography during VATS segmentectomy. METHODS: We retrospectively reviewed the records of 22 consecutive patients who underwent VATS segmentectomy performed with near-infrared angiography between November 2014 and October 2015...

The real-time endoscopic colour and fluorescence-merged imaging system, using intravenous injection of indocyanine green (ICG), allows a clear surgical view, which facilitates identification of the pulmonary inter-segmental plane in thoracoscopic surgery. However, the staining time is too short to mark and cut the intersegmental plane, because the mean washout time of ICG is only a few minutes in the clinical setting. To overcome this limitation, we have developed a new technique for prolongation of ICG staining time...

Precise clinical knowledge of liver anatomy is required to safely perform a hepatectomy, for both open and laparoscopic surgery. At the 19th meeting of the Japanese Research Society of Clinical Anatomy (JRSCA), we conducted special symposia on essential issues of liver surgery, such as the history of hepatic segmentation, the glissonean pedicle approach, application of 3-D imaging simulation and fluorescent imaging using indocyanine green solution, a variety of segmentectomies including caudate lobectomy, the associating liver partition and portal vein embolization for stage hepatectomy and harvesting liver grafts for living donor liver transplantation...

Segmentectomy using indocyanine green (ICG) has become a primary treatment option to achieve a complete resection and preserve lung function in early-stage lung cancer. However, owing to a lack of appropriate intraoperative imaging systems, it is a huge challenge for surgeons to identify the intersegmental plane during the operation, leading to poor prognosis. Thus, we developed a novel wireless wearable fluorescence image-guided surgery system (LIGHTEN) for fast and accurate identification of intersegmental planes in human patients...

BACKGROUND: Pulmonary segmentectomy with radical lymphadenopathy has been considered effective to manage small primary lung cancers [1, 2]. This procedure provides the advantages of minimal invasive surgery and is reported sufficient for safe margin. However, segmentectomy is more difficult to be performed than lobectomy because intersegmental plane cannot be detected easily. Several methods have been reported for identifying the actual intersegmental plane [3-7], but the sensitivity of these methods is limited to the lung conditions like patients with emphysematous lung and needed skilled surgeon to perform...

Minimally invasive surgery for liver resections has a defined role and represents an accepted alternative to open techniques for selected cases. Robotic technology can overcome some of the disadvantages of the laparoscopic technique, mainly in the most complex cases. Precise dissection and microsuturing is possible, even in narrow operative fields, allowing for a better dissection of the hepatic hilum, fine lymphadenectomy, and biliary reconstruction even with small bile ducts and easier bleeding control. This technique has the potential to allow for a greater number of major resections and difficult segmentectomies to be performed in a minimally invasive fashion...

The maintenance of a good surgical view is mandatory in video-assisted thoracoscopic surgery (VATS). For routine segmentectomy, it is necessary to re-inflate the lung in order to identify the intersegmental borders. However, such re-inflation can occasionally obstruct the surgical view and can lead to prolongation of operation time, particularly in the context of VATS. Infrared thoracoscopy( IRT) with indocyanine green (ICG) is a new method of evaluating lung perfusion. There are 2 methods in IRT. One is based on ICG absorption, and the other is based on ICG fluorescence...

BACKGROUND: To determine factors predicting indocyanine green (ICG) visualization during fluorescence imaging for segmental plane formation in thoracoscopic anatomical segmentectomy. METHODS: Intraoperatively, the intravenous ICG fluorescence imaging system during thoracoscopic anatomical segmentectomy obtained fluorescence emitted images of its surfaces during lung segmental plane formation after the administration of 5 mg/body weight of ICG. The subtraction of regularization scale for calculating the exciting peaks of ICG between the planned segments to resect and to remain was defined as ΔIntensity (ΔI)...

PURPOSE: It is important to minimize surgical invasiveness in the therapy of patients with hepatocellular carcinoma (HCC), and consequently laparoscopic hepatic resection is widely performed. However, most anatomical resections, except left lateral sectionectomy, remain difficult technically, and laparoscopy-assisted procedures have been introduced as an alternative approach because of the safety and curative success of the operation. We reported previously pure laparoscopic subsegmentectomy of the liver using puncture of the portal branch under percutaneous ultrasound (US) with artificial ascites...
