Introduction Cannulation is difficult in patients with periampullary diverticulum (PAD). The described success rate varies from 61% to 95.4%. Material and methods Four cases with PAD in which, despite repeated attempts, we were unable to locate the papilla and cannulate. To overcome this difficulty, we used SpyBite forceps (Boston Scientific) to pull out the papillary orifice and then perform...

BACKGROUND The guidewire biliary cannulation (GWC) technique may increase the cannulation rate and decrease the risk for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. The aim of our multicenter prospective randomized controlled trial was to determine if the use of an atraumatic loop-tip guidewire reduces the rate of post-ERCP pancreatitis (PEP) compared with the stand...

OBJECTIVES To determine the safety of thrombolytic treatment in patients with central venous cannulation. BACKGROUND Thrombolytic treatment significantly reduces mortality in patients with myocardial infarction. Because of the fibrinolytic state induced and the potential for haemorrhagic complications, thrombolysis is currently considered a strong relative contraindication in patients who hav...

Two cases of delayed non-mycotic false aneurysm arising from ascending aortic cannulation site, presenting one-and-a-hald years and seven years after cardiopulmonary bypass, are described. These two cases represent an incidence of 0.12% of this complication. Repair using profound hypothermia and circulatory arrest with femoral artery and femoral vein cannulation for cardiopulmonary bypass is re...

Individuals with major depressive disorder (MDD) display abnormal neurophysiological responses to psychological stress but little is known about their neurophysiological responses to physiological stressors. Using [(15)O-H(2)O] positron emission tomography we assessed whether the regional cerebral blood flow (rCBF) response to arterial cannulation differed between patients with MDD and healthy ...

Background: Venous cannulation is the most commonly performed invasive procedure in hospital patients. It is painful and associated with a high incidence of vasovagal reactions and pressor responses in patients. Objectives: The aim of the study is to evaluate the efficacy of eutectic mixture of local anesthetic cream in producing dermal analgesia for venous cannulation. Material and Method: 200...

BACKGROUND Intravenous cannulation is a very common procedure. Venous aneurysm secondary to peripheral intravenous cannulation is extremely rare. Moreover, venous aneurysm can mimic other conditions and may confuse the issue. CASE PRESENTATION We describe a case of a 45-year-old woman who was referred with the diagnosis of varicose vein of right arm. A history of intravenous cannulation at th...

BACKGROUND Epidural analgesia is commonly used to provide several types of pain relief. Although this technique has been widely used with many advantages, currently the complications appear to be increasing. Especially, inadvertent intravascular cannulation and intravascular local anesthetic administration can lead to fatal consequences. METHODS Data was collected on 296 patients undergoing e...

BACKGROUND Experimental results suggest that the competence of the internal jugular vein (IJV) valve may be damaged when the IJV is cannulated for insertion of a central venous catheter. It has further been hypothesized that the risk of causing incompetence of the proximally located valve might be reduced by using a more distal site for venous cannulation. The present study evaluated these hypo...

BACKGROUND/OBJECTIVES Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP) have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center. METHODS All patients undergoing first time ERCP at a tertiary referral cente...
