PURPOSE Clostridium difficile (C. difficile)-associated colitis, a known complication of colon and rectal surgery, can increase perioperative morbidity and mortality, leading to increased hospital stay and costs. Several contributing factors, including advanced age, mechanical bowel preparation, and antibiotics, have been implicated in this condition. The purpose of this study was to determine ...
Double-J (DJ) stent is placed temporarily in the ureter after urology surgery and is removed after 2-6 weeks. It is relatively rare for a patient to forget about the indwelling DJ ureteral stent. Major complications associated with such situation include DJ fracture, infection and encrustation. Increasing the thickness of the stent causes the adhesion of the urinary tract, therefore, the stent ...
BACKGROUND Anastomotic leaks after low anterior resection for rectal cancer remain the most feared complication. The aim of our study was to investigate whether the use of a transanal tube could reduce the leakage rate after this surgical procedure. METHODS This is a retrospective analysis of a single-institution experience. The study includes 66 patients who underwent low anterior resection ...
OBJECTIVE We retrospectively performed a comparative analysis of temperature measurement sites during surgical repair of the thoracic aorta. METHODS Between January 2004 and May 2006, 22 patients (mean age: 63 ± 12 years) underwent operations on the thoracic aorta with arterial cannulation of the aortic arch concavity and selective antegrade cerebral perfusion (ACP) during deep hypothermic ci...
A procedure was explained to fabricate a surgical stent to aid the placement of maxillofacial implants for prosthetic auricular rehabilitation. An impression of the defect was made, and a wax pattern of the missing ear completed and evaluated on the patient. The definitive wax prosthesis was processed in clear acrylic resin. Also an occlusal maxillary splint was fabricated and joined to the acr...
conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...
Background and Purpose:Coronary artery Stenting is known to improve the outcome for ischemic heart disease. Many clinical studies have been performed to determine the long-term outcome of coronary Stenting and most of them were based on first-generation bare-metal Stents. The aim of this study is to evaluate long-term (24 6.4 month) results of second-generation bare metal stent. Materials an...
