Following the introduction of the first laparoscopic liver resection, after ∼25 years, a critical reappraisal seems to be warranted. Liver resection represents the first choice for curing early hepatocellular carcinoma (HCC) allowing a curative chance also in selected patients with intermediate stage tumors. The criteria for liver resectability by laparoscopy remains the same for open surgery, which is oncological criteria (absence of extrahepatic tumor location; completely resectable R0 resection), anatomic (resectability of involved segment with its own blood surely and biliary drainage; absence of vascular invasion of portal or hepatic veins) and technical (possibility to leave in place a residual volume ≥40%)...

OBJECTIVES: Although wedge resection can be curative for small lung tumours, tumour marking is sometimes required for resection of non-palpable or visually undetectable lung nodules as a method for identification of tumours. Tumour marking sometimes fails and occasionally causes serious complications. We have performed many thoracoscopic segmentectomies using 3D computed tomography simulation for undetectable small lung tumours without any tumour markings. The aim of this study was to investigate whether thoracoscopic segmentectomy planned with 3D computed tomography simulation could precisely remove non-palpable and visually undetectable tumours...

OBJECTIVE: Anatomic resection of the dorsal area of the basal segment of the lower lobe is difficult because of the deep location of vessels and bronchi in the parenchyma. This study aimed to describe a novel technique for port-access thoracoscopic segmentectomy of the dorsal (S10) and lateral dorsal segments (S9+10). METHODS: This retrospective study analyzed 20 patients who underwent S10 and S9+10 thoracoscopic segmentectomy via a posterior approach between January 2004 and March 2016...

BACKGROUND: When hepatocellular carcinoma (HCC) was located in segment 2 (S2), segment-oriented hepatectomy was more beneficial than left lateral sectionectomy as this type of anatomical resection preserved the volume of the nontumor-bearing segment. Herein, we presented 2 cases (1 with video) of laparoscopic anatomical S2 segmentectomy by the Glissonian approach. METHODS: The first patient was a 69-year-old woman, who had an incidentally detected liver nodule on abdominal ultrasound for systemic surveillance for her breast cancer...

INTRODUCTION: Minimally invasive surgery is the treatment of choice in early-stage lung cancer. However, experience in infectious lung disease, primarily bronchiectasis, is limited probably because of the presence of dense pleural adhesions, multiple lymph nodes, and spiral bronchial arteries. The present study shows our experience of video-assisted thoracoscopic surgery (VATS) lobectomy and segmentectomy in the treatment of bronchiectasis. MATERIALS AND METHODS: Patients who underwent VATS lobectomy or segmentectomy in our clinic between April 2008 and 2015 were retrospectively evaluated...

OBJECTIVES: Anatomical lobar resection and mediastinal lymphadenectomy remain the standard for the treatment of early stage non-small-cell lung cancer (NSCLC) and are preferred over procedures such as segmentectomy or wedge resection. However, there is an ongoing debate concerning the influence of the extent of the resection on overall survival. The aim of this article was to assess the overall survival for different types of resection for Stage I NSCLC. METHODS: We performed a retrospective analysis of the results of the surgical treatment of Stage I NSCLC...

BACKGROUND: For primary lung cancer, anatomic pulmonary segmentectomy may have a functional advantage over lobectomy; however, persistent air leak or delayed pneumothorax after segmentectomy is prevalent and increases surgical morbidity. To prevent pulmonary complications after pulmonary segmentectomy, we used 2 methods for the involved intersegmental plane: coverage using polyglycolic acid mesh and fibrin glue (mesh cover) or closing it by suturing the pleural edge (pleural suture). We aimed to compare postoperative pulmonary function and complications between the 2 groups...

OBJECTIVES: The impact of skip N2 metastases (i.e. N2 lymph node metastases without N1) on survival in surgically resected non-small lung cancer remains an intriguing and rarely investigated topic. The goal of our study was to elucidate (i) skip N2 influence on overall survival (OS) and time to recurrence (TTR) in patients with resected lung adenocarcinoma and (ii) its link with epidermal growth factor receptor ( EGFR ) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog ( KRAS ) mutations...

OBJECTIVES: Although robotic-assisted thoracic surgery (RATS) provides improved dexterity, the effect of RATS on pain compared with video-assisted thoracoscopic surgery (VATS) or open lobectomy is poorly understood. This study evaluated acute and chronic pain following RATS, VATS, and open anatomic pulmonary resection. METHODS: A retrospective review of 498 patients (502 procedures) who underwent RATS (74), VATS (227), and open (201) anatomic pulmonary resection including lobectomy and segmentectomy from 2010 to 2014 was performed to identify factors related to acute and chronic pain...

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...

PURPOSE AND DESIGN: Standard treatment for early-stage non-small cell lung cancer has traditionally involved lobectomy. Historical data that demonstrates suboptimal results for sublobar resection compared to lobectomy have been challenged in recent years with retrospective data for patients with T1a disease. For patients who are not candidates for lobectomy, options for sublobar resection include wedge resection or anatomic segmentectomy. Segmentectomy has long been held to be a better cancer operation than wedge resection, and its role in treating early-stage lung cancer remains controversial in patients who are candidates for lobectomy...

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...

PURPOSE: Liver resection in hepatic sarcoma is rare, but other alternative treatment options are scarce. Surgery offers the only aggressive approach to achieve a tumour-free state. The aim of this investigation was to evaluate the outcome and survival of these patients at a single hepato-biliary university hospital. METHODS: Between January 2004 and July 2013, 896 anatomical liver resections were performed. Eleven liver resections (1.2%) were performed due to primary hepatic sarcoma or hepatic sarcoma metastases...

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...
