rainage systems in pneumothorax and also suggested that digital thoracic drainage systems might be a valuable tool to determine chest tube removal timing and reducing the length of hospital stay in patients with pneumothorax.

Minimally invasive approach through a right mini-thoracotomy is a world-wide used procedure for mitral valve surgery. We performed a retrospective analysis based on our center experience in order to propose an effective, safe and reproducible method using an intra-aortic occlusion device.

This is a retrospective analysis on 48 consecutive patients undergoing mitral valve surgery through a right anterolateral mini-thoracotomy in our center. An intra-aortic occlusion device was used for aortic clamping and cardioplegia delivery. Simultaneous multi-plane three-dimensional echocardiography imaging was acquired to detect the venous cannulas position, the intra-aortic device location in the ascending aorta, the balloon inflation, the complete occlusion of the aorta, the cardioplegia delivery, the origin and the blood flow in the right coronary artery. Aortic root pressure was measured by the tip of the intra-aortic occlusion device. A bilateral upper extremity invasive arterial pressure monitoring was detected.nd reproducible method in patients undergoing minimally invasive valve surgery using an intra-aortic occlusion device.

The optimal cannulation site for repair of type A aortic dissection remains controversial. The concern for Malperfusion syndrome has initiated a national trend away from femoral cannulation to axillary artery and direct ascending aortic cannulation. The purpose of this study was to report a single center experience with femoral artery cannulation for the repair of a type A dissection.

A retrospective study was performed on 52 patients who underwent surgical repair for a type A dissection between January 1

, 2012 and June 30

, 2019 at a single institution. Of the 52 patients analyzed, 35 (67.3%) underwent femoral artery, 11 (21.2%) direct ascending aortic, and 6 (11%) axillary artery cannulation for arterial access. Deep hypothermic circulatory arrest was used in all the patients. Rates of postoperative complication and mortality were reported.

The mortality and bleeding rates for all the patients undergoing repair of the type A dissection repairs were 27% (14/52) and 19% (10/52), respectively. Cardiopnd produces excellent results for establishing cardiopulmonary bypass. The concerns for malperfusion syndrome related to femoral cannulation were not seen.

The effect of perioperative chemotherapy on patients with lymph node-negative esophageal cancer (EC) is controversial. This study explored which EC patients, staged under the T1-3N0M0, would benefit from perioperative chemotherapy.

Data on patients with diagnosed primary EC were retrieved from Surveillance, Epidemiology and End Results (SEER) database. Propensity score-matched (PSM) method was performed to balance baseline covariates. Multivariate Cox regression analysis and Kaplan-Meier curve were used to assess potential survival difference between patients undergoing surgery plus perioperative chemotherapy (SA + CT) and those undergoing surgery alone (SA).

In a total of 2,711 EC patients (T1-3N0M0), 166 patients underwent SA + CT and 2,545 patients received SA. In the multivariable analysis, T stage was significantly related to prognosis of EC patients before and after matching. Subgroup analysis showed that perioperative chemotherapy was associated with poor cancer-specific survival (CSS) for stage T1 patients. click here There was no effect of perioperative chemotherapy on overall survival (OS) or CSS for T2 patients, whereas a remarkable improvement in OS and CSS was observed for T3 patients. Survival analysis showed that T3 stage EC patients obtained survival benefit from SA + CT. Prognosis in the SA group was significantly better than in the SA + CT group for T1 patients. However, T2 patients showed no significant increase in survival after undergoing SA + CT compared with SA.

T3 patients benefit more from SA + CT. However, perioperative chemotherapy does not present survival benefit to T1-2 patients, and it is an adverse prognostic factor for T1 patients.

Lung cancer death rates and incidence in both men and women have decreased over the past two decades. However, certain subsets of non-small cell lung cancer (NSCLC) have arisen with poor outcomes. Identifying factors which contribute to poorer outcomes as well as those that inform early detection strategies remain unmet needs. We present data from a contemporaneous group of NSCLC patients that received care at a single University teaching hospital to understand clinical and pathological factors influencing outcomes in the past decade.

A cohort of 2,289 patients with NSCLC who established care at the Rogel Cancer Center, University of Michigan between January 2011 and April 2019 were identified. Patient characteristics and clinical outcomes were recorded using electronic health records. The Kaplan-Meier method and the Cox proportional model were used to assess relationship between clinic-pathological factors and survival.

Of the 2,289 patients, 92% were >50 years of age while 8% were <50 years of as to understand cost-benefit ratio of follow- up cross sectional imaging of all patients diagnosed with unprovoked pneumonia, including in younger non/current smokers.

Solitary pulmonary nodules caused by nontuberculous mycobacteriosis are included as a category of pulmonary nontuberculous mycobacterium disease. Clinical characteristics, treatments and prognosis are not fully known because there are a few related reports.

This was a multi-center retrospective study of 101 cases diagnosed as solitary nodular type of nontuberculous mycobacteriosis from January 2000 to March 2017 that underwent resection at 9 related facilities belonging to the Thoracic Surgery Study Group of Osaka.

The most common pathogen was

(n=77, 87.5%), followed by

(n=8, 9.1%). Chest computed tomography results showed subpleural locations that were difficult to distinguish from lung cancer. Fluorodeoxyglucose positron emission tomography/computed tomography was performed in 58 cases and positive results were obtained in 35 (60.3%), with an average maximum standardized uptake value of 3.87. The purpose of resection in most cases was for diagnosis. The surgical procedure was wedge resection in 87, segmentectomy in 3, and lobectomy in 11, while 77 underwent thoracoscopic surgery.
