Filter by:In 2009, Prof. Hohenberger proposed complete mesocolic excision (CME) as standardized, in which the same principle of TME in rectal cancer has been applied to the colon. More and more surgeons pay attention to the rationality of this surgical approach. However, the clinical application researches are still few, in particular the prospective controlled study is still none. This clinical trial will compare the CME group and non-CME group to evaluate the outcome and safety of CME for apply in clinic.
This is a multi-center cluster-randomized trial with the following Specific Aims: - To evaluate if continuous noninvasive hemoglobin monitoring will reduce the RBC transfusions in patients undergoing surgeries associated with a significant risk of bleeding. - To evaluate if patients monitored with continuous noninvasive hemoglobin experience less frequent complications and shorter hospital stay compared with patients who are not being monitored with continuous noninvasive hemoglobin. Accordingly, the study hypotheses are defined as follows: - The primary null hypothesis is that continuous noninvasive hemoglobin monitoring will not reduce the RBC transfusions in patients undergoing surgeries associated with a significant risk of bleeding. - The secondary hypothesis is that in patients monitored with continuous noninvasive hemoglobin, there will be earlier warning of critical drops in hemoglobin, and thus, there will be less frequent complications compared with patients who are not being monitored with continuous noninvasive hemoglobin.
A study will be conducted to determine if there is any cognitive benefit in elderly patients having open versus minimally invasive colon cancer surgery.
To demonstrate that clinical surrogates of SICU patients who view a video decision aid in addition to receiving written and verbal information about procedures and life sustaining therapy in the SICU make more informed decisions than patients and clinical surrogates who receive written and verbal information alone.
In recent years, the safety and efficacy of autologous bone marrow stem cells infusion (ABMSCi) therapy were confirmed. The investigators attempted to infuse autologous bone marrow stem cells (ABMSC) through inserting a catheter into right gastric artery as far as proper hepatic artery after finishing open abdominal portal hypertension surgery. The present study was designed to treat bleeding from esophageal varices and hypersplenism and hopefully to improve the liver function as well.
The Percutaneous drainage of symptomatic intra-abdominal collection (primary or secondary to surgery)is the treatment of choice in the absence of peritonitis signs. In critically ill patients, this procedure allows to avoid or postpone surgery. In these settings, the percutaneous drain can be either in Active Vacuum Pressure or in Free drainage. However, no prospective trials has assessed the efficiency of these two modalities of drainage in cases of infected intra-abdominal collections. The investigators aimed then to prospectively analyzed the efficiency (in term of infectious control) of drainage under active vacuum pressure vs. free drainage for the treatment of infected intra-abdominal collections.
There is increased frequency of asthma in obese patients. This study is trying to find out if there is a difference in the presence of bronchospasm during anesthesia in obese and non obese patients.
Type 2 diabetes mellitus (T2DM) is a relevant public health problem and obesity has been associated as the major risk factor. Roux-en-Y gastric bypass is an effective method to treat severe obesity, and its metabolic benefits can lead to early and complete remission of T2DM, even before a considerable weight loss. We have hypothesized that intestinal anatomic changes may change intestinal genes expression related to glycemic control. The knowledge of mechanisms mediating the glycemic control after Roux-en-Y gastric bypass and it site of action in bowel may eventually help to develop alternative, less invasive and safer surgery for the treatment of T2DM, as well as drug development for the newly targets identified.
Reload of high dose statin may have potential for preventing deep vein thrombosis (DVT) in patients on statin undergoing total knee replacement arthroplasty. A body of evidence have been reported that reloading of atorvastatin have efficacy in reducing periprocedural myocardial infarction and contrast induced nephropathy. These effects are considered to be mainly due to their antioxidant anti-thrombotic and anti-inflammatory property. We, therefore, hypothesize that high dose atorvastatin re-loading may prevent DVT.
Systolic function is a substantial determinant of overall hemodynamics and organ function. Therefore assessment of left ventricular systolic function (LVF) has been of central interest in Echocardiography. Ejection fraction (EF) measurement has been the gold standard echo-derived measure to describe LVF. However, EF is a blood pool derived and therefore load dependent measure. Global longitudinal peak systolic strain average is a new parameter derived from speckle tracking tachnique. As a primarily myocardial deformation parameter it is considered to be an equivalent to EF measurement, but maybe less load dependend. The aim of the study is to investigate the reliability of GLPSS average to quantify LVF in the perioperative setting (in cardiac and non-cardiac cases).
