BACKGROUND AND OBJECTIVE: Standard surgical management for early stage lung cancer is lobectomy with mediastinal lymph node dissection. The feasibility of limited resection remains controversial; we retrospectively assessed lung cancer-specific survival (LCSS) and overall survival (OS) in early stage non-small cell lung cancer (NSCLC) to evaluate whether segmentectomy is comparable to standard lobectomy. METHODS: Patients with primary NSCLC of 20 mm or less who were diagnosed from 2000 to 2014 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database...

BACKGROUND: This study aimed to compare the survival rates after lobectomy, segmentectomy and wedge resection for the eighth edition of stage IA non-small cell lung cancer (NSCLC). METHODS: Patients who underwent lobectomy, segmentectomy or wedge resection for stage IA NSCLC were identified from the Surveillance, Epidemiology and End Results database. A Cox regression model and propensity-matched analysis were used. The overall survival (OS) rates and lung cancer-specific survival (LCSS) rates amongst the three groups were compared by tumor size...

BACKGROUND: Because left upper division resection is similar to right upper lobectomy, this procedure is frequently employed. Few studies have used the anatomic courses of veins evaluated on preoperative computed tomography (CT) imaging to determine what types of patients are at the highest risk for hemorrhagic pulmonary infarction. CASE: We describe our experience with a patient in whom hemorrhagic pulmonary infarction occurred at 6 days after transecting two superior branches (V1 and V3 ) of the three branches of the left superior pulmonary vein...

BACKGROUND: Lung nodules that are small and deep within lung parenchyma, and have semisolid characteristics are often challenging to localize with video-assisted thoracoscopic surgery (VATS). We describe our cumulative experience using needle localization of small nodules before surgical resection. We report procedural tips, operative results, and lessons learned over time. METHODS: A retrospective review of all needle localization cases between July 1, 2006, and December 30, 2016, at a single institution was performed...

Background: The presence of air leak following lung resection remains a frequent problem, which may prolong hospital stay and increase hospital costs. In the past, some studies documented the efficacy of soft and flexible chest tube in patients who underwent thoracic surgery. Nevertheless, safety in case of post-operative large air or liquid leak remains questionable. The objective of this study was to verify through a multicentre study the safety and the effectiveness of the coaxial chest tube in a consecutive series of selected patients who underwent anatomical pulmonary resection and with an active and large air leak...

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)...

BACKGROUND: Anatomic segmentectomy for stage I nonsmall cell lung cancer (NSCLC) has potential advantages such as preserving pulmonary function and reducing postoperative complications. However, many surgeons are deterred from this procedure for its anatomical complexity. Therefore, we presented our early experience with video-assisted thoracoscopic surgery (VATS) anatomic segmentectomy compared with our most recent VATS lobectomy cases. PATIENTS AND METHODS: Forty patients with cT1aN0M0 (ground-glass opacity [GGO] rate >50%) NSCLC underwent VATS segmentectomy from January 2015 to December 2016...

BACKGROUND: Segmentectomy for radiologically pure solid tumors is still controversial because these tumors are more aggressive in malignancy than those with ground-glass opacity. This study aimed to determine the feasibility of intentional segmentectomy for pure solid small-sized lung cancer. METHODS: We retrospectively analyzed 96 radiologically pure solid tumors in clinical T1a-bN0M0 lung cancer. Patients whose tumor was located at a central region or right middle lobe were excluded...

This report describes the case of an 85-year-old man who underwent left hemicolectomy for descending colon cancer and hepatic segmentectomy for metastatic liver cancer. Seven years after the liver surgery, an abdominal CT scan revealed a tumor in the remnant liver. He also presented with colon diverticula in the ascending colon, which was located close to the liver tumor. With a preoperative diagnosis of metastatic liver cancer, the tumor was resected with S8 segmentectomy. Histopathological examination of the resected tumor revealed a hepatic inflammatory pseudotumor, not metastatic liver cancer...

A 60-year-oldman was diagnosedwith ascending colon cancer with multiple bilobar metastases. He then received7 courses of tegafur-gimeracil-oteracil andoxaliplatin (SOX)plus panitumumab as downstaging chemotherapy. This treatment significantly reducedthe size of the metastatic tumor, andwe subsequently triedto perform a curative resection. A twostage hepatectomy was plannedto avoidthe risk of hepatic failure from small future liver remnant. First, the anterior segmentectomy andthe left portal vein ligation were performed...

A 60-year-old man was admitted for a liver mass(S3), which rapidly increased in size during intraductal papillary mucinous neoplasm(IPMN)follow-up. Although EOB-MRIwas performed, the mass could not be accurately diagnosed as hepatic cancer. Thus, we performed a lateral segmentectomy. In the resected specimen, a solid tumor mass was clearly bound in segment 3 of the liver. Since histopathology revealed no malignant cells and many IgG4-positive cells, we confirmed the diagnosis as IgG4-related inflammatory pseudotumor of the liver...

The patient was a 65-year-old man who had been previously diagnosed with chronic hepatitis B, but the patient had discontinued treatment while in his thirties. The patient was admitted to the emergency department after losing consciousness due to abdominal pain. Emergency contrast CT was performed in the shock state, and the diagnosis was hemorrhagic shock due to rupture of hepatocellular carcinoma(HCC). Emergency TAE was performed, and hemostasis was successful due to left hepatic arterial embolism. The tumor was confined to the liver lateral area and it was judged to be resectable curatively, upon state restoration...

a-fetoprotein(AFP)-producing gastric cancer is relatively rare and tends to show a poor prognosis because of hepatic and lymph node metastasis. We experienced a case of AFP-producing gastric cancer with synchronous liver metastasis wherein the patient survived for 5 years without recurrence after undergoing surgery and adjuvant chemotherapy. A 39-year-old woman was admitted to our hospital complaining of tarry stool. Upper gastrointestinal endoscopy revealed a 40mm type 2 tumor in the greater curvature of the lower gastric body, and abdominal CT indicated a 50mm liver metastasis at the S2 segment...

Carcinoma with elevated SRC expression is associated with distant metastasis and drug resistance. We report 2 cases of SRC amplification observed after retrospective comprehensive genomic sequencing. Case 1 was a 62-year-old man who had RAS wild-type stage IV carcinoma of the sigmoid colon with multiple liver metastases in both lobes. He underwent low anterior resection and systemic chemotherapy was initiated to treat the unresectable multiple liver metastases. Case 2 was a 73-yearold man who had RAS wild-type stage IV carcinoma of the descending colon with metastasis in the lateral segment of the liver...

The patient was a 77-year-old man with a 4.0 cm hepatictumor in hepaticsegment 4. Plain computed tomography(CT) showed the tumor with low density. On dynamicexamination, the tumor showed heterogeneous enhancement during the arterial phase. Magneticresonanc e imaging showed the tumor as a low intensity area in the hepatobiliary phase in hepatic segments 4, 6, and 8. A month later, CT showed an enlarged tumor in segment 4 measuring 7.0 cm. We diagnosed the tumor as primary liver cancer and suspected it to be hepatocellular carcinoma(HCC)preoperatively...

BACKGROUND: Minimally invasive surgery of pulmonary nodules allows suboptimal palpation of the lung compared to open thoracotomy. OBJECTIVE: The objective of this study was to assess endoscopic pleural dye marking using radial endobronchial ultrasound (r-EBUS) and virtual bronchoscopy to localize small peripheral lung nodules immediately before minimally invasive resection. METHODS: The endoscopic procedure was performed without fluoroscopy, under general anesthesia in the operating room immediately before minimally invasive surgery...

Anatomical segment resections are often technically more demanding than lobectomies. Anterior segment of the left upper lobe (S3) is usually removed within the standard resection of the upper three segments.    Our patient in this case was a 56-year-old with a known oropharyngeal carcinoma, otherwise amenable to curative treatment, who was admitted to our clinic with  a 1-cm nodule in the anterior segment of the left upper lobe.  Distant metastases were excluded, and a decision was made to proceed with a uniportal video-assisted thoracoscopic segmentectomy and lymphadenectomy...
