61. Radiofrequency turbinate volume reduction vs. radiofrequency-assisted turbinectomy for nasal obstruction caused by inferior turbinate hypertrophy. (Abstract)

Radiofrequency turbinate volume reduction vs. radiofrequency-assisted turbinectomy for nasal obstruction caused by inferior turbinate hypertrophy. Radiofrequency procedures are a well-accepted treatment for nasal obstruction. We conducted a randomized, noncontrolled study to compare the effectiveness of submucosal bipolar radiofrequency turbinate volume reduction (RFTVR) and bipolar radiofrequency-assisted turbinectomy (RFaT) in patients presenting with nasal obstruction caused by inferior (...) . However, we noted that the incidence of adverse effects and postoperative morbidity was higher in the RFaT group. Therefore, we conclude that when surgery is indicated, RFTVR is the preferred treatment for nasal obstruction secondary to inferior turbinate hypertrophy. RFaT is equally effective, but it is associated with a slightly higher incidence of adverse effects.

63. Evaluation of combined radiofrequency and chemical blockade of multi-segmental lumbar sympathetic ganglia in painful diabetic peripheral neuropathy Full Text available with Trip Pro

Evaluation of combined radiofrequency and chemical blockade of multi-segmental lumbar sympathetic ganglia in painful diabetic peripheral neuropathy Painful diabetic peripheral neuropathy (PDPN) is one of the most common complications of diabetes. PDPN seriously affects the quality of life and is difficult to treat; therefore, there is an urgent need for new cost-effective treatment methods for PDPN.To investigate the efficacy and safety of radiofrequency thermocoagulation (RF) combined (...) temperature (ST) and the improvement of numbness and hyperalgesia in the lower extremities, complications, and degree of satisfaction (DOS) before and after surgery.Postoperative VASs were significantly decreased compared to preoperative VASs in all groups (P<0.05). The VAS in group A began to increase 3 months (3M) after surgery; VAS scores at 3M, 6 months (6M) and 1 year (1Y) were significantly different compared to group B and C (P<0.05); VAS in group B began to increase after 6M; VAS scores at 6M

67. Radiofrequency ablation for the treatment of Barrett?s esophagus with high-grade and low-grade dysplasia: An update

(Figure 2). Radiofrequency ablation (RFA) delivers high frequency alternating current to the mucosa using the BÂRXX (formerly HALO) system (Covidien, Sunnyvale, CA), with the aim of destroying neoplastic mucosa and allowing for the regeneration of normal squamous epithelia. RFA is typically administered to mucosa that is flat (i.e. there are no villi or pits) because RFA is not recommended if there is submucosal invasion of the dysplastic cells. The BÂRXX system provides two types of devices (...)

72. Two-year results of a multicenter randomized controlled trial comparing Mechanochemical endovenous Ablation to RADiOfrequeNcy Ablation in the treatment of primary great saphenous vein incompetence (MARADONA trial). (Abstract)

Two-year results of a multicenter randomized controlled trial comparing Mechanochemical endovenous Ablation to RADiOfrequeNcy Ablation in the treatment of primary great saphenous vein incompetence (MARADONA trial). Endothermal techniques have proved to be effective for treatment of incompetent truncal veins. The tumescentless mechanochemical ablation (MOCA) technique has become an alternative treatment modality, but its outcome with regard to endothermal techniques is still unclear.A (...) multicenter prospective randomized controlled trial was designed comparing MOCA with radiofrequency ablation (RFA) to treat great saphenous vein incompetence with the hypothesis that MOCA is associated with less postprocedural pain and a comparable anatomic and clinical success rate at 1-year follow-up. Disease-specific quality of life and general health-related quality of life (HRQoL) were measured using questionnaires.

73. Remote ischaemic preconditioning ameliorates sinus rhythm restoration rate through Cox maze radiofrequency procedure associated with inflammation reaction reduction. (Abstract)

Remote ischaemic preconditioning ameliorates sinus rhythm restoration rate through Cox maze radiofrequency procedure associated with inflammation reaction reduction. Remote ischaemic preconditioning (RIPC) as adjuvant to selective heart surgery attenuates cardiac injury and atrial fibrillation (AF) occurrence. We investigated its effect on sinus rhythm (SR) restoration rate in permanent AF patients undergoing Cox maze (CM) radiofrequency ablation with concomitant mitral valve surgery. From May (...) 2013 to May 2017, 206 patients with rheumatic valve disease concomitant with permanent AF were randomized to receive prosthesis valve replacement and CM radiofrequency ablation procedure with (n = 104) or without (n = 102) RIPC (intermittent arm ischaemia through three cycles of 5-min inflation, followed by 5-min deflation of a blood pressure cuff). The primary end point of the study was freedom from cumulative AF without using antiarrhythmic drugs 1 year after operation; the secondary end points

74. A Randomized Controlled Trial to Evaluate the Effect of Pulsed Radiofrequency as a Treatment for Anterior Cutaneous Nerve Entrapment Syndrome in comparison to Anterior Neurectomy. (Abstract)

A Randomized Controlled Trial to Evaluate the Effect of Pulsed Radiofrequency as a Treatment for Anterior Cutaneous Nerve Entrapment Syndrome in comparison to Anterior Neurectomy. Chronic abdominal pain can be due to entrapped intercostal nerves (anterior cutaneous nerve entrapment syndrome [ACNES]). If abdominal wall infiltration using an anesthetic agent is unsuccessful, a neurectomy may be considered. Pulsed radiofrequency (PRF) applies an electric field around the tip of the cannula near (...) ) of the neurectomy group (P = 0.073). Thirteen patients were withdrawn from their scheduled surgery. Adverse events were comparable between treatments.PRF appears to be an effective and minimally invasive treatment option and may therefore be considered in patients who failed conservative treatment options before proceeding to a neurectomy procedure. Anterior neurectomy may possibly lead to a greater pain relief compared with PRF in patients with ACNES, but potential complications associated with surgery should

76. Pulsed radiofrequency to the dorsal root ganglion or the sciatic nerve reduces neuropathic pain behavior, decreases peripheral pro-inflammatory cytokines and spinal β-catenin in chronic constriction injury rats. (Abstract)

Pulsed radiofrequency to the dorsal root ganglion or the sciatic nerve reduces neuropathic pain behavior, decreases peripheral pro-inflammatory cytokines and spinal β-catenin in chronic constriction injury rats. Pulsed radiofrequency (PRF) is a minimal neurodestructive interventional pain therapy. However, its analgesic mechanism remains largely unclear. We aimed to investigate the peripheral and spinal mechanisms of PRF applied either adjacent to the ipsilateral L5 dorsal root ganglion (PRF (...) -DRG) or PRF to the sciatic nerve (PRF-SN) in the neuropathic pain behavior induced by chronic constriction injury (CCI) in rats.On day 0, CCI or sham surgeries were performed. Rats then received either PRF-DRG, PRF-SN, or sham PRF treatment on day 4. Pain behavioral tests were conducted before surgeries and on days 1, 3, 5, 7, 9, 11, 13, and 14. After the behavioral tests, the rats were sacrificed. The venous blood or sciatic nerve samples were collected for ELISAs and the dorsal horns of the L4

Radiofrequency ablation of turbinates after septoplasty has no effect on allergic rhinitis symptoms other than nasal obstruction. In this study we evaluated the effects of inferior turbinate radiofrequency ablation (RFA), performed after septoplasty, on patients with allergic rhinitis (AR) symptoms.This was a prospective, randomized, controlled study involving 60 patients with both a deviated nasal septum (DNS) and AR. Those who underwent septoplasty/sham surgery constituted the Septo-Sham (...) between the groups. The 2 types of surgery improved both the NOSE and SFAR scores. In subgroup analysis according to the type of symptoms, both types of surgery showed improvement in SFAR-NO and SFAR-SONO scores. However, the extent of improvement did not differ between the groups, regardless of the type of symptoms.For patients with both DNS and AR, both types of surgery afford postoperative symptomatic improvement. Both types of surgery yielded improvement in both nasal obstruction and symptoms
