Clinical Outcomes of Atypical Inflammatory Variants of Abdominal Aortic Aneurysm.

Background: Most abdominal aortic aneurysms are degenerative atherosclerotic aneurysms. Inflammatory or infected abdominal aortic aneurysms, which show a slightly different clinical course, are rarely encountered in clinical settings. Therefore, we aimed to investigate the clinical course of these variants of abdominal aortic aneurysms.

Risk Factors of On-Pump Conversion during Off-Pump Coronary Artery Bypass Graft.

Background: Off-pump coronary artery bypass grafting (OPCABG) procedures can avoid the complications of an on-pump bypass. However, some cases unexpectedly require conversion to cardiopulmonary bypass during OPCABG. The risk factors associated with a sudden need for cardiopulmonary bypass were analyzed.

Impact of Lifestyle Diseases on Postoperative Complications and Survival in Elderly Patients with Stage I Non-Small Cell Lung Cancer.

Background: The influence of lifestyle diseases on postoperative complications and long-term survival in patients with non-small cell lung cancer (NSCLC) is unclear. The aim of this study was to determine whether lifestyle diseases were significant risk factors of perioperative and long-term surgical outcomes in elderly patients with stage I NSCLC.

Methods: Between December 1995 and November 2013, 110 patients aged 65 years or older who underwent surgical resection of stage I NSCLC at Dong-A University Hospital were retrospectively studied.

Prediction and prognostic factors of post-recurrence survival in recurred patients with early-stage NSCLC who underwent complete resection.

Background: This study aimed to evaluate prognostic factors of post-recurrence survival (PRS) and to improve survival in recurred patients with early-stage non-small cell lung cancer (NSCLC).

Methods: The 141 patients with recurrence after complete resection of stage I and II NSCLC between 1995 and 2012 was retrospectively reviewed. Overall PRS and PRS of the patient groups stratified according to the sum of their own risk scores were analyzed.

Prognosis of recurrence after complete resection in early-stage non-small cell lung cancer.

Background: Tumor recurrence is the most common cause of treatment failure, even after complete resection of early-stage non-small cell lung cancer (NSCLC). In this study, we investigated the prognosis of patients with early recurrence in order to identify independent risk factors related to early recurrence.

Methods: Between February 1995 and December 2012, 242 patients who underwent surgical resection for stage I NSCLC at Dong-A University Hospital were reviewed.
