OBJECTIVES: Upper lobectomy inevitably leads to an upward displacement of the remaining lower lobe. Such displacement may result in bronchial angulation, thereby narrowing the airway. We hypothesized that the degree of displacement of the bronchus is associated with the degree of exacerbation of postoperative pulmonary dysfunction. This study investigated whether bronchial angulation affects postoperative pulmonary function. METHODS: Patients undergoing upper lobectomy for lung cancer were retro

BACKGROUND: This study analyzed the relation between the tumor size and the lymph node metastasis in adenocarcinoma of the lung with a size of 30 mm or smaller. METHODS: Four hundred thirteen patients who had undergone curative resection for lung adenocarcinoma were enrolled. If the tumor presented ground-glass opacities on the preoperative high-resolution computed tomography, both the total size including ground-glass opacities and the solid size alone were measured. To calculate the rates of l

Boerhaave's syndrome is the most severe disease in the esophageal perforation. The purpose of this report is to evaluate the outcome in patients who were treated with primary repair for Boerhaave's syndrome regardless of the time interval. From 1997 to July 2007, 10 patients with Boerhaave's syndrome were treated with primary repair regardless of the time interval. The interval between rupture and initial treatment was less than 24 hours in five patients (50.0%) and more than 24 hours in the oth

OBJECTIVES: This study was conducted to investigate the prognostic factors of pulmonary metastases, focusing on the time of detection of pulmonary metastases related to adjuvant chemotherapy in patients with colorectal cancer (CRC). METHODS: Between June 2003 and December 2010, 84 patients underwent pulmonary metastasectomy for pulmonary metastasis (PM) from CRC. The clinicopathological data of colorectal surgery and pulmonary metastasectomy were analysed retrospectively. Disease-free intervals

This study aimed to investigate the efficacies and complications associated with the 7F catheter inserted in patients with pneumothorax in the emergency room and to compare the results for primary and secondary pneumothorax. From June 2006 to May 2008, 200 patients with primary or secondary pneumothorax treated with a 7F catheter were enrolled. The primary endpoint was the immediate success rate. Success with the 7F catheter was defined as complete or nearly complete lung expansion following ins

BACKGROUND AND OBJECTIVES: This study evaluated the relationship between the maximum standardized uptake value (SUVmax) of preoperative positron emission tomography/computed tomography (PET/CT) and the characteristics of lung adenocarcinoma featuring ground-glass opacity nodules (GGN). METHODS: The association of the SUVmax of preoperative PET/CT with ground-glass opacity (GGO) proportion on CT, subtypes of adenocarcinoma (minimally invasive adenocarcinoma, invasive adenocarcinoma), predominant
