101. Radiofrequency hemorrhoidectomy: less is less? Results of a comparative study. (Abstract)

Radiofrequency hemorrhoidectomy: less is less? Results of a comparative study. Radiofrequency has been introduced as an instrument conceived to upgrade the conventional treatment of hemorrhoidectomy. To reduce the economic aspect, recently has been introduced a new radiofrequency device: VojantTM. Aim was to compare clinical outcomes of hemorrhoidectomy with LigaSureTM and VojantTM, performed with the Milligan- Morgan technique, in medium-term perspective.Between January 2016 and December 2016 (...) , 50 consecutive patients with symptomatic grade III and IV were scheduled for surgical treatment. Patients were assigned randomly to undergo either VojantTM or LigaSureTM haemorrhoidectomy. All preoperative and postoperative data were collected.Patients in the LigaSureTM group experienced less pain than those treated by VojantTM, (p<0.05). In VojantTM group one patient developed immediate postoperative bleeding (within 48 h), the other one seven days after surgery. Complete wound healing

104. Efficacy of microwave ablation versus radiofrequency ablation for the treatment of hepatocellular carcinoma in patients with chronic liver disease: a randomised controlled phase 2 trial. (Abstract)

Efficacy of microwave ablation versus radiofrequency ablation for the treatment of hepatocellular carcinoma in patients with chronic liver disease: a randomised controlled phase 2 trial. Radiofrequency ablation is the recommended treatment for patients with hepatocellular carcinoma who have lesions smaller than 3 cm and are therefore not candidates for surgery. Microwave ablation is a more recent technique with certain theoretical advantages that have not yet been confirmed clinically. We aimed (...) to compare the efficacy of both techniques in the treatment of hepatocellular carcinoma lesions of 4 cm or smaller.We did a randomised controlled, single-blinded phase 2 trial at four tertiary university centres in France and Switzerland. Patients with chronic liver disease and hepatocellular carcinoma with up to three lesions of 4 cm or smaller who were not eligible for surgery were randomised to receive microwave ablation (experimental group) or radiofrequency ablation (control group).

105. Prospective, double-blind, randomized controlled trial comparing electrocoagulation and radiofrequency in the treatment of patients with great saphenous vein insufficiency and lower limb varicose veins. (Abstract)

Prospective, double-blind, randomized controlled trial comparing electrocoagulation and radiofrequency in the treatment of patients with great saphenous vein insufficiency and lower limb varicose veins. 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.This was a prospective, double-blind, randomized clinical trial. Patients with lower limb varicose veins and GSV reflux confirmed by duplex ultrasound were randomized into two treatment groups: EC and RFA. Patients were followed up at 1 week, 3 months, and 6 months after

106. Ocular blood flow alterations during inferior turbinate radiofrequency reduction under local anesthesia. (Abstract)

Ocular blood flow alterations during inferior turbinate radiofrequency reduction under local anesthesia. Ocular blood flow alterations and blindness are uncommon and less-known adverse effects of nasal local anesthetic infiltrations. Our aim was to investigate ocular blood flow alterations during radiofrequency (RF) tissue reduction of inferior turbinates with the patient under local anesthesia by using a noninvasive method with optical coherence tomography.A total of 120 patients with inferior (...) turbinate hypertrophy were prospectively randomized into two groups. In group 1, a total of 61 patients underwent RF tissue reduction while under local anesthesia with epinephrine. In group 2, a total of 59 patients underwent RF tissue reduction of inferior turbinates while under local anesthesia without epinephrine. Optical coherence tomography measurements were performed before surgery and at 5, 15, 30, 45, and 60 minutes after local anesthetic infiltration.Choroid thickness measurements decreased

108. Radiofrequency Microdebridement Versus Surgical Decompression for Achilles Tendinosis: A Randomized Controlled Trial. (Abstract)

Radiofrequency Microdebridement Versus Surgical Decompression for Achilles Tendinosis: A Randomized Controlled Trial. Achilles tendinosis is primarily managed nonoperatively with activity modification and physiotherapy, although surgery can be required. This has classically involved surgical decompression of the Achilles tendon, although the use of radiofrequency microdebridement has been suggested as a novel minimally invasive alternative. We present a randomized controlled trial comparing (...) radiofrequency microdebridement using the Topaz® microdebrider wand and traditional surgical decompression. All patients with Achilles tendinosis referred to a single surgeon and meeting the inclusion criteria were invited to participate in our single-blinded, randomized controlled study. The Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire and the visual analog scale were used as measures at baseline and 6 months postoperatively. From 2009 to 2014, 16 patients were randomized

110. Cardiac tamponade after radiofrequency ablation for hepatocellular carcinoma: Case report and literature review. Full Text available with Trip Pro

Cardiac tamponade after radiofrequency ablation for hepatocellular carcinoma: Case report and literature review. Radiofrequency ablation (RFA) is a safe and effective local treatment modality with a low complication rate and is commonly used to treat hepatocellular carcinoma (HCC). The clinical outcome of RFA may be closely related to the location, size, and shape of index tumors, and major complications, including hemorrhage, liver abscess, infarction, visceral organ perforation, hemothorax (...) in segment IVa of left hepatic lobe. As the patient was at high risk for surgery because of poor lung function, RFA was selected as the treatment of choice. The index tumor was located in the vicinity of the diaphragm and colon. During RFA procedure, thermal injury to the adjacent diaphragm and colon was minimized by introducing artificial ascites. Bleeding or tumoral seeding was prevented by ablating the electrode track during electrode retraction.Two hours after RFA, the patient presented with dyspnea
