BACKGROUND: Ganglionated plexuses (GP) are terminal parts of cardiac autonomous nervous system (ANS). Radiofrequency ablation (RFA) for atrial fibrillation (AF) possibly affects GP. Changes in heart rate variability (HRV) after RFA can reflect ANS modulation. METHODS: Epicardial RFA of GP on the left atrium (LA) was performed under the general anesthesia in 15 mature Romanov sheep. HRV was used to assess the alterations in autonomic regulation of the heart. A 24 - hour ECG monitoring was performed before the ablation, 2 days after it and at each of the 12 following months...

OBJECTIVE: Thermoablation has been replacing conventional surgery in the surgical treatment of great saphenous vein (GSV) reflux in patients with lower limb varicose veins; however, thermoablation is expensive. Intravenous electrocoagulation (EC) may, selectively and safely, cause necrosis of the GSV wall, but the clinical results have never been studied. The objective of this study was to compare EC and radiofrequency ablation (RFA) in the treatment of GSV insufficiency, considering efficacy, complications, and effect on quality of life...

The current standard of treating early Barrett's neoplasia is resection of visible lesions using endoscopic mucosal resection (EMR) followed by ablative therapy to the Barrett's segment. There is increasing evidence to support the use of endoscopic submucosal dissection (ESD) where en-bloc resection and lower recurrence rates may be achieved. However, ESD is associated with deep submucosal dissection when compared to EMR. This may increase the risk of complications including stricture formation with subsequent radiofrequency ablation (RFA) therapy...

REVIEW
Sundeep Lakhtakia
Pancreatic neuroendocrine tumors (PNETs) are increasingly being detected, though usually as incidental findings. Majority of the PNETs are non-functional and surgical resection is the standard of care for most of them. However, in patients with small PNETs localized within the pancreas, who are unfit or unwilling for surgery, alternate methods of treatment are needed. Direct methods of ablation of PNETs, using either ethanol injection or radiofrequency ablation (RFA), are emerging as effective methods. The limited literature available as case reports or case series on endoscopic ultrasound (EUS)-guided local ablation using either ethanol or RFA has demonstrated safety and efficacy along with short- to medium-term sustained relief...

BACKGROUND: Cholangiolocellular carcinoma (CoCC) is a rare liver tumor arising from the canals of Hering found between the cholangioles and interlobular bile ducts. Although morphologically CoCC mimics intrahepatic cholangiocarcinoma (ICC), CoCC exhibits a unique intermediate biologic behavior between hepatocellular carcinoma (HCC) and ICC. Curative resection is required for prolonged survival in patients with CoCC. However, effective therapy for postoperative hepatic recurrence has not yet been standardized...
