Perforation after endoscopic retrograde cholangiopancreatography (ERCP) is a rare but severe complication. Management of ERCP-associated duodenal perforation remains controversial. Some recommend surgery, while others recommend conservative treatment. We describe the case who developed perforation of the duodenum and gas in the retroperitoneal cavity after ERCP. There was no sign of peritonitis...

Background: Endoscopic Retrograde Cholangio Pancreatography (ERCP) is the commonest method for treatment of biliary stones. In our study we compared 2 groups of patients managed with laparoscopic cholecystectomy post ERCP after maximum of 72 hours during same admission and after 28 days. Patients and Methods: The study conducted from January 2012 to January 2015 and included 86 patients; Group ...

Pancreatitis is a common serious complication of endoscopic retrograde cholangio-pancreatography (ERCP) with reported incidence rates from 2 to 40%. Prediction of post-ERCP pancreatitis and its severity is useful for planning treatment strategy (surveillance, intensive care therapy, use of novel drugs like platelet activating factor antagonist, parenteral nutrition). The commonly used criteria ...

Two different measures of the retention of avoidance conditioning, frequently used in the investigation of retrograde anmesia (RA), were examined. Rats were given a single training trial on either passive or active avoidance in a conventional black-white discrimination apparatus and step•through latencies were recorded. Task sequence, footshock and hypothermia were experimentally varied across ...

Endoscopic retrograde cholangiopancreatography (ERCP) is an essential modality for the diagnosis and therapy of pancreatobiliary disease. However, complications of ERCP-related procedures are also common. Post-ERCP pancreatitis (PEP), the most common and potentially serious complication of ERCP-related procedures, occurs in 1 9% of all procedures (1-16). Moreover, the PEP rate increases to 10 4...

We investigated the applicability of the pre-embedding immunoperoxidase technique to WGAapoHRP-Au retrograde tracing. After injection of the tracer into the substantia nigra of rat, the brain was fixed and cryostat sections were immunostained for dopamine. The sections were osmicated and silver-stained to amplify the colloidal gold particles. Products of both the immunoperoxidase staining and t...

Single, biocytin filled neurons in combination with immunocytochemistry and retrograde tracing as well as material with traditional double-immunolabeling were used at the light and electron microscopic levels to study the neural circuitry within the basal forebrain. Cholinergic neurons projecting to the frontal cortex exhibited extensive local collaterals terminating on non-cholinergic, (possib...

Nigrostriatal neurons expressing RET protein, a receptor protein tyrosine kinase of glial cell line-derived neurotrophic factor (GDNF) were investigated in rats using retrograde neural tracing with horseradish peroxidase (HRP) combined with immunohistochemistry. HR/RET double-labeled neurons were abundantly distributed in the substantia nigra pars compacta ipsilateral to the caudate-putamen ste...

The projection of spinal neurons to the lateral reticular nucleus of the rat was investigated with a non-fluorescent double retrograde tracing technique. Either a gold-lectin tracer or cholera toxin-b-subunit was injected into the lateral reticular nucleus on each side of the brain. Retrogradely labeled neurons were encountered bilaterally throughout the spinal cord. Double labeled neurons, how...

Contradictory results have been reported about the inhibitory input to the medial rectus subdivision of the oculomotor nucleus of the cat. In the present ultrastructural study, we quantified the GABAergic and glycinergic terminals in the various subdivisions of the rabbit oculomotor nucleus with the use of post-embedding immunocytochemistry combined with retrograde tracing of horseradish peroxi...
