BACKGROUND The purpose of this study was to compare perioperative outcomes in patients who underwent video-assisted thoracoscopic surgery or robot-assisted thoracoscopic surgery and assess the feasibility of robotic-assisted thymectomy for the treatment of Masaoka stage I. METHODS We evaluated the short-term outcomes of 46 patients who underwent surgery for Masaoka stage I thymoma without mya...

BACKGROUND Internal drainage of giant pancreatic pseudocysts secondary to acute pancreatitis is frequently complicated with postoperative retroperitoneal infection and hemorrhage. Recent data suggest that the risk factor is unrecognized pancreatic necrosis; presumably, pancreatic necrosis becomes infected with bacteria introduced by the cystoenteric anastomosis. HYPOTHESIS Video-assisted panc...

SAGD (steam-assisted gravity drainage) technique is one of the most efficient thermal recovery technologies for exploiting Mackay River thin layer oil sand reservoirs. However, when making use traditional (the production and injection well are located on same axis with horizontal spacing 0 m), steam chamber development usually insufficient because high longitudinal sweep rate steam, which serio...

Gas and downhole water sink-assisted gravity drainage (GDWS-AGD) is a new process of enhanced oil recovery (EOR) in reservoirs underlain by large bottom aquifers. The capital intensive as it requires the construction dual-completed wells for production additional multiple vertical gas-injection wells. costs could be substantially reduced eliminating using triple-completed multi-functional These...

The effectiveness of use of thoracoscopy for esophageal perforation has not been fully evaluated. We herein report a case of esophageal perforation for which a transabdominal approach assisted by thoracoscopic drainage was performed.

Vacuum-assisted closure therapy is an alternative method for a massive subcutaneous emphysema treatment. It is easily applicable and shows rapid effectiveness in massive subcutaneous emphysema, intractable with chest tube drainage.

Introduction: The treatment of complicated parapneumonic effusion (PPE) and thoracic empyema (TE) is controversial; and the choice of treatment after confirming the failure of simple drainage remains unclear. The purpose of this study was to compare the outcomes of intrapleural urokinase (UK) administration and video-assisted thoracoscopic surgery (VATS) as initial treatment options for PPE and...
