BACKGROUND: The interest for endoscopic pulmonary anatomic resections has grown exponentially during the last decade. During thoracoscopic procedures surgeons cannot rely on digital handling and operative field is viewed on a two-dimensional video monitor, thus frequently encountering anatomical difficulties. The hypothesis is that foreknowledge of the anatomy of each patient would greatly contribute to the safety and accuracy of the operation. The aim of the study was to evaluate the effectiveness of 3dimensional multidetector computed tomography (3D-MDCT) software to identify the pulmonary artery branching pattern during the preoperative study of endoscopic lobectomies and segmentectomies...

BACKGROUND: Anatomical liver resection has been reported to have oncologic benefit over nonanatomical resection in surgery for hepatocellular carcinoma (HCC). Basic concept of anatomical resection is preventing tumor spread through the portal or venous flow. Few cases have been reported for laparoscopic anatomical segment 8 resection because of its technical difficulties. This video shows operative techniques for laparoscopic anatomical resection of segment 8, exposing middle and right hepatic vein and inferior vena cava using three-dimensional video...

Anatomical segmentectomies play an important role in oncological lung resection, particularly for ground-glass types of primary lung cancers. This operation can also be applied to metastatic lung tumors deep in the lung. Virtual assisted lung mapping (VAL-MAP) is a novel technique that allows for bronchoscopic multi-spot dye markings to provide "geometric information" to the lung surface, using three-dimensional virtual images. In addition to wedge resections, VAL-MAP has been found to be useful in thoracoscopic segmentectomies, particularly complex segmentectomies, such as combined subsegmentectomies or extended segmentectomies...

Thoracoscopic pulmonary segmentectomy is technically meticulous due to the complicated anatomical variations of segmental bronchus and vessels. Currently three dimensional-computed tomography angiography (3D-CTA) could only meet the simple requirements of segmentectomy. Our center developed a software for reconstruction, "deepinsight", which could effectively solve some key technical problems. Preoperative three-dimensional computed tomography bronchography and angiography (3D-CTBA) could reveal the anatomical structures and improve the accuracy of operation...

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...
