The objective of this study was to determine the safety and efficacy of percutaneous endobiliary radiofrequency ablation (ERFA) and balloon dilation for the treatment of hepaticojejunostomy (HJ) strictures resistant to surgery and/or other interventions.

Endobiliary radiofrequency ablation (RFA) is a new endoscopic ablative technique. However, the ideal power setting for RFA has not yet been clarified. Therefore, we intended to evaluate the effects of...
Most patients with distal extrahepatic cholangiocarcinoma have developed jaundice or cholangitis at the time of initial diagnosis, which can delay surgery. We aim to evaluate the actual EB-RFA ablatio...
Biliary strictures can be broadly classified as benign or malignant. Benign biliary strictures are most commonly iatrogenic in nature and are a consequence of hepatobiliary surgery. Cholangiocarcinoma...
Endoscopic ultrasound (EUS)-guided antegrade stenting combined with hepaticogastrostomy is useful in patients with malignant biliary stricture complicated by duodenal obstruction. Biliary radiofrequen...
There are just short series of radiofrequency of sphenopalatine ganglion (SPG) to treat chronic refractory cluster headache (CCHr) with variable results. Furthermore, there is no consensus on which me...
Only a small proportion of patients with biliary obstruction caused by hepatopancreatobiliary malignancies are suitable for surgical resection. Therefore, most patients with malignant bili...
Endobiliary radiofrequency ablation (RFA) with biliary stent has been reported to be a beneficial treatment option for palliation of malignant biliary strictures. RFA uses a high-frequency...
Efficacy and Safety of Endobiliary Radiofrequency Ablation by Using a Novel RF Catheter (ELRA®) on Maintaining the Patency of Endobiliary Metal Drainage in Patients With Malignant Biliary Strictures : A Double-arm Comparable Study
Malignant obstructive jaundice is a common complication of advanced stage cholangiocarcinoma, gallbladder cancer, and pancreatic cancer. In biliary stricture by malignancy, biliary drainag...
The purpose of the present protocol is to evaluate the response rate to treatment of these symptomatic benign nodules with radiofrequency as an alternative to surgical treatment. This thy...
This phase-2 study aims to evaluate feasibility, safety and efficacy of thermal ablation of biliary obstructive malignancies by means of radiofrequency ablation (RFA, ELRA, StarMed) during...
Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
The application, via IMPLANTED ELECTRODES, of short bursts of electrical energy in the radiofrequency range, interspersed with pauses in delivery of the current long enough to dissipate the generated heat and avoid heat-induced tissue necrosis.
Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
A benign, autosomally recessive inherited hyperbilirubinemia characterized by the presence of a dark pigment in the centrilobular region of the liver cells. There is a functional defect in biliary excretion of bilirubin, cholephilic dyes, and porphyrins. Affected persons may be asymptomatic or have vague constitutional or gastrointestinal symptoms. The liver may be slightly enlarged, and oral and intravenous cholangiography fails to visualize the biliary tract.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
