PURPOSE The goal of this study was to compare the rate of systemic inflammatory response syndrome (SIRS) in high-risk patients undergoing percutaneous nephrolithotomy (PCNL) between patients who received 7, 2, or 0 days of preoperative antibiotics. MATERIALS AND METHODS We retrospectively reviewed a series of consecutive PCNLs performed at our institution. Patients with infected preoperative ...

background: we performed this study to evaluate the efficacy of melatonin, clonidine and gabapentin in reducing preoperative anxiety and postoperative pain in patients undergoing laparoscopic cholecystectomy. methods: this study was a randomized clinical trial on patients scheduled for laparoscopic cholecystectomy. a total number of 88 patients were categorized into four groups to receive melat...

Objective The aim of this study was to evaluate the impact of preoperative hypoalbuminemia on the development of intra-abdominal septic complications (IASCs) after primary anastomosis for patients with Crohn's disease (CD). Methods All CD patients undergoing bowel resection with a primary anastomosis during the study period from 2007 to 2015 were enrolled. The association of preoperative hypo...

BACKGROUND The Revised Cardiac Risk Index (RCRI) is useful for risk stratifying patients before noncardiac operations. Among patients with documented coronary artery disease who undergo vascular surgery, it is unclear whether preoperative revascularization reduces postoperative cardiac complications in high-risk subsets defined by the RCRI. METHODS AND RESULTS The Coronary Artery Revasculariz...

abstract background and aims: probable risk factors of clinical anastomotic leakage and the role of defunctioning stoma in patients undergoing low anterior resection (lar) for rectal cancer, is still controversial. the goal of our study was to find out possible risk factors of anastomotic leakage and to locate the influence of protective stoma in the rate of anastomotic leakage. materials and m...

BACKGROUND Acute kidney injury (AKI) after cardiac surgery is associated with poor outcomes and is difficult to predict. We conducted a prospective study to evaluate whether preoperative brain natriuretic peptide (BNP) levels predict postoperative AKI among patients undergoing cardiac surgery. METHODS AND RESULTS The Translational Research Investigating Biomarker Endpoints in Acute Kidney Inj...

background: there are some conflicting results with conventional coronary artery bypass grafts (ccabg) with arrested heart in coronary high-risk patients. moreover, performing off-pump cabg in these cases may be associated with serious complications. the objective of this study is to evaluate the efficacy of the on-pump beating cabg (opbcabg) in coronary high-risk patients in comparison with th...
