Thoracoscopic anatomic pulmonary segmentectomy and subsegmentectomy have become sophisticated surgical solutions for complex pulmonary diseases. The rapid development of three-dimensional computed tomographic angiography (3DCTA) has made it possible to provide more refined individualized anatomic details and has consequently enabled subsubsegmentectomy (SSS). In this study, we report two successful thoracoscopic anatomic SSSs of the left S(1+2)aii and S(3)aii under the guidance of 3DCTA reconstructed images...

BACKGROUND: Computed tomography (CT)-guided lung needle marking is useful to identify pulmonary nodules. However, certain complications sometimes trigger severe after-effects or death. So, we present a convenient and safe method by which small pulmonary nodules can be identified using a particular dye [2% (w/v) gentian violet]. METHODS: A patient is initially placed in the lateral operative position. Under CT guidance, a "magic marker" is used to identify the skin above the pulmonary nodule...

The major lung resections are the pneumonectomies and lobectomies. The sublobar resections are segmentectomies and wedge resections. These are performed either through open surgery through a thoracotomy or by video-assisted mini-invasive surgery for lobectomies and sublobar resections. Understanding the procedures involved allows the normal postoperative appearances to be interpreted and these normal anatomical changes to be distinguished from potential postoperative complications. Surgery results in a more or less extensive physiological adaptation of the chest cavity depending on the lung volume, which has been resected...

BACKGROUND: Stapling is becoming the method of choice for dividing the intersegmental plane during thoracoscopic segmentectomies. The technique however is controversial as it can impair re-expansion of preserved segments. We have analyzed the morbidity and lung re-expansion on a series of 175 thoracoscopic segmentectomies. METHODS: A total of 175 patients underwent a thoracoscopic anatomic segmentectomy. Ten patients were excluded due to conversion into thoracotomy...

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether there is a specific subgroup of patients that would benefit from pulmonary metastasectomy for colorectal carcinoma (CRC). A total of 524 papers were identified using the reported search, of which 1 meta-analysis, 1 systematic review and 17 retrospective studies represented the best evidence to answer the clinical question. The authors, date, journal, country, study type, population, outcomes and key results are tabulated...

Endobronchial lipomas are rare benign tumors whose symptoms are usually confused with recurrent infections or even asthma diagnosis, and mostly caused by endobronquial obstructive component which also conditions severity. We report a case of a 60-year-old man with a right-lower lobe upper-segment endobronchial myxoid tumor with uncertain diagnosis. We performed a single incision video-assisted anatomical segmentectomy and wedge bronchoplasty with handsewn closure to achieve complete resection and definitive diagnosis...

OBJECTIVES: Sublobar resection is advocated for patients with NSCLC and compromised cardiopulmonary reserve, and for selected patients with early stage disease. Anatomic segmentectomy (AS) has traditionally been considered superior to wedge resection (WR), but well-balanced comparative studies are lacking. We hypothesize that WR and AS are associated with comparable oncologic outcomes for patients with cT1N0 NSCLC. METHODS: A retrospective review of a prospective database was performed (2000-2014) for cT1N0 patients, excluding patients with multiple primary tumors, carcinoid tumors, adenocarcinoma in situ, and minimally invasive adenocarcinoma...

The objective of this study was to assess the clinical impact of laparoscopic hepatectomy from technical and oncological viewpoints through the consecutive 5-year experience of an expert team. The subjects consisted of 491 consecutive hepatectomies performed over the course of 5 years. A total of 190 hepatectomies (38.6 %) were performed laparoscopically, and the remaining 301 (61.4 %) were open hepatectomies. Chronological trends of operative procedures and their indications were evaluated, and patients with hepatocellular carcinoma (HCC) were analyzed from an oncological viewpoint...

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...

OBJECTIVE: Thoracic surgeons must be erudite pulmonary vein variation when performing anatomical segmentectomy. We used three-dimensional CT (3DCT) to accumulate variations of the pulmonary veins of the right upper lobe (RUL) and created a simplified RUL vein model. METHODS: We reviewed anatomical variations of the RUL pulmonary veins of 338 patients using 3DCT images, and classified them by position related with bronchus. RESULTS: Of the "anterior" and "central" RUL veins, all could be classified into 4 types: 2 Anterior with Central types (Iab and Ib), 1 Anterior type, and 1 Central type...

The combination of hilar cholangiocarcinoma and anatomic variation constitutes a rare and complicated condition. Precise understanding of 3-dimensional position of tumor in the intrahepatic structure in such cases is important for operation planning and navigation. We report a case of a 61-year woman presenting with hilar cholangiocarcinoma. Anatomic variation and tumor location were well depicted on preoperative multidetector computed tomography (MDCT) combined with 3-dimensional reconstruction as the right posterior segmental duct drained to left hepatic duct...

The case was 83-year-old man who had complete situs inversus, and was pointed out to have peripheral adenocarcinoma with the size of 1.8 cm at the left upper lobe( S3). Because of severe emphysema and other multiple comorbidities, left S3 segmentectomy with hilar lymph node sampling was performed using video-assisted thoracic surgery (VATS). Preoperatively, the simulation of operation was performed using the 3 dimension computed tomography images of pulmonary arteriovenous and bronchus (3DCTAB). Postoperative course was uneventful...
