Background: Chronic radiation proctitis (CRP) occurs up to 20 % of patients after pelvic radiotherapy, with rectal bleeding as the main presenting complaint. Radiofrequency ablation (RFA) has recently been used in the management of Barrett's esophagus, but its efficacy in CRP has to be studied. The aim of this case series was to describe four cases of patients with CRP treated with RFA that demonstrate the efficacy and safety of the technique.
Methods: All the procedures were performed with HALO 90 or HALO 90 Ultra ablation catheter fitted on the distal end of a standard flexible endoscope. For each patient, the severity of symptoms was assessed at baseline and after the last treatment session.
Results: At least two sessions of RFA (maximum 4) were necessary, at three-month intervals, to completely control the symptoms. No major complications were observed.
Conclusions: RFA was effective and safe for control bleeding in this case series. Adequately powered randomized controlled trials are needed to establish the safety and efficacy of RFA for CRP.

Background: The efficacy of microwave ablation (MWA) and radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) patients with decompensated cirrhosis remains unclear.
Methods: A total of 315 patients with decompensated cirrhosis and HCC who underwent MWA or RFA were recruited. Recurrence beyond the Milan criteria (RBM), local tumor progression (LTP), overall survival (OS), and complications were evaluated and compared.
Network meta-analysis of the efficacy of endoscopic cardia peripheral tissue scar formation (ECSF) in the treatment of gastroesophageal reflux disease.

Endoscopic antireflux therapy is widely used in clinical practice. Peroral endoscopic cardial constriction (PECC), antireflux mucosal intervention (ARMI), and radiofrequency ablation (RF) possess analogous antireflux mechanisms. This comprehensive systematic review and meta-analysis aimed to evaluate and compare the safety and effectiveness of antireflux therapy during endoscopic cardia peripheral tissue scar formation (ECSF) procedures.

Background: Pulmonary vein isolation (PVI) is the most promising management method for paroxysmal atrial fibrillation (PAF). The P wave in the electrocardiogram (ECG) represents atrial depolarization. This study aims to correlate P-wave parameters after PVI with outcomes.

Background: Catheter ablation is a key treatment for atrial fibrillation (AF), with high-power, very high-power short-duration and pulsed field ablation (PFA) being efficient options. However, direct comparisons between these techniques are lacking.
Objective: We performed a systematic review and meta-analysis, which included predominantly observational studies (four retrospective and one prospective study), to compare PFA and High-power short-duration (HPSD) and very high-power short-duration (vHPSD) radiofrequency (RF) ablation in patients with AF.
Pulsed Field Ablation (PFA) is a new ablation method being rapidly adopted for treatment of atrial fibrillation, which shows advantages in safety and efficiency over radiofrequency and cryo-ablation. In this study, we used an in vivo swine model (10 healthy and 5 with chronic myocardial infarct) for ventricular PFA, collecting intracardiac electrograms, electro-anatomical maps, native T1-weighted and late gadolinium enhancement MRI, gross pathology, and histology. We used 1000-1500 V pulses, with 1-16 pulse trains to vary PFA dose.
