Abstract
INTRODUCTION AND HYPOTHESIS The objective was to evaluate the clinically beneficial effect of adding transvaginal monopolar non-ablative radiofrequency (RF) to pelvic floor muscle training (PFMT) on leakage severity, quality of life and urinary incontinence-related symptoms in women with stress urinary incontinence (SUI). METHODS A double-blind randomised controlled trial was conducted, with a 6-week intervention and a 6-month follow-up. Participants were randomly assigned to the experimental group (PFMT plus RF; n = 18) or the control group (PFMT plus placebo; n = 20). The primary outcome was the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF). Secondary outcomes included the Pelvic Floor Distress Inventory-20 (PFDI-20) and the Pelvic Floor Impact Questionnaire-7 (PFIQ-7), self-efficacy, female sexual function, pelvic floor muscle dynamometry, 1-h pad test and number of SUI episodes per week. Inferential analyses of the data were performed using a two-factor analysis of variance. RESULTS Both groups achieved a statistically significant improvement in ICIQ-SF over time. However, the differences observed in the experimental group exceeded the minimal clinically important differences by 4 points (MD = -9.4, 95% CI = -12.6 to -6.3), which was not observed in the control group (MD = -3.9, 95% CI = -6.9 to -1.0). This was maintained at the 6-month follow-up with a significant time*group interaction (p < 0.001, ηp2 = 0.150). There was no time*group interaction in the other variables (p > 0.05). Additionally, a significant difference in favour of the experimental group was observed in the 1-h pad test and episodes of SUI per week (p < 0.05). CONCLUSIONS This study highlights the beneficial effects of adding transvaginal RF to PFMT on the severity and amount of leakage, as well as on the quality of life and urinary incontinence-related symptoms in women with moderate SUI. Future trials are needed to assess the effects of this intervention in women with severe SUI.

Abstract
Pulsed radiofrequency is a well-documented treatment option for multiple painful conditions where pulses of energy are delivered close to neural elements. Since its earliest adoption, this technique has gained increasing acceptance as a minimally invasive procedure, and new applications are evolving. Studies have shown microscopic and biochemical changes that reflect beneficial effects; however, the exact mechanism of action is not yet completely understood. To redress this paucity, 11,476 articles of scientific relevance published between 1980 and November 2022 were mined through a search of the PubMed database, arriving at 49 studies both in animals and humans. In general, the experimental studies examined have shown that pulsed radiofrequency induces multiple changes with antinociceptive and neuromodulatory effects. These modifications include changes in neural and glial cells, synaptic transmission, and perineural space. Studies also reveal that pulsed radiofrequency regulates inflammatory responses, cellular signaling proteins, and the expression of genes related to pain transmission, acting in biological processes in structures such as myelin, mitochondria, axons, glial cells, connective tissue, regulation of proteins, ion channels, and neurotransmitters.

Abstract
Gastroesophageal reflux disease (GERD) has been growing globally, with an increasing burden on the healthcare system due to multiple factors, such as aging and obesity. The current study evaluated the feasibility of endoscopic balloon-assisted laser treatment (EBLT) in a porcine model. GERD was initially developed in three animals via botulinum toxin injection into lower esophageal sphincter (LES). A week after the injection, the EBLT was performed on the GERD-developed models (control = 1 vs. treated = 2). A dose of 30 W of 980 nm laser light was endoscopically applied for 90 s to the LES. Both endoscopic ultrasound and manometry were performed before and after the EBLT. After 12 weeks, esophageal tissues were extracted and prepared for histological analysis. The maximum mucosa temperature was below 50 °C during the EBLT. Compared to control, the treated group yielded thicker and shorter LES muscle layers and maintained LES pressure. Through histology, the EBLT reinforced the muscularis layer with preserved mucosa and mild remodeling of the intermuscular collagen in the LES. The current study demonstrated the feasibility of EBLT as a new endoscopic approach for GERD. Further studies will examine the EBLT in a larger number of animals to warrant efficacy and safety for clinical translations.

Abstract
OBJECTIVE We aimed to describe the action, impact on quality of life, and side effects of perianal nonablative radiofrequency (RF) application in the treatment of anal incontinence (AI) in women. METHODS This was a pilot, randomized clinical trial conducted between January and October 2016. We enrolled women who consecutively attended the Attention Center of the Pelvic Floor (CAAP) with complaints of AI for more than six months. Nonablative RF was applied to the perianal region of the participants using Spectra G2 (Tonederm®, Rio Grande do Sul, Brazil). The reduced or complete elimination of the need for protective undergarments (diapers and absorbents) was considered a partial therapeutic response. RESULTS Nine participants reported treatment satisfaction, while one reported dissatisfaction with the nonablative RF treatment of AI based on the Likert scale. No patient interrupted treatment sessions because of adverse effects, although adverse effects occurred in six participants. However, the clinical and physical examination of the participants with burning sensations showed no hyperemia or mucosal lesions. CONCLUSIONS This study showed a promising reduction of fecal loss, participant satisfaction with treatment, and improved lifestyle, behavior, and depression symptoms with minimal adverse effects.

Abstract
There have been many devices and ideas to treat reflux disease endoscopically. Several devices have been tried and even FDA approved but now are no longer used. The push for these therapies is to find effective reflux control with lower risk and faster recovery. In this article we describe an endoscopic suturing device (TIF), radiofrequency device (Stretta) and a newer technique that has a lot of promise called antireflux mucosectomy. All these procedures seem to help control reflux at a minimum of morbidity given current information. As reflux is so prevalent a shift to these techniques for appropriate patients is likely to improve patient care.

Abstract
Benign anorectal disorders of structure and function are common in clinical practice. These guidelines summarize the preferred approach to the evaluation and management of defecation disorders, proctalgia syndromes, hemorrhoids, anal fissures, and fecal incontinence in adults and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was assessed using the Grading of Recommendations Assessment, Development and Evaluation process. When the evidence was not appropriate for Grading of Recommendations Assessment, Development and Evaluation, we used expert consensus to develop key concept statements. These guidelines should be considered as preferred but are not the only approaches to these conditions.

Abstract
AIM A study to compare the effect of two different radio frequency energy models (mono polar and bipolar) for the treatment of urinary stress incontinence. METHODS Retrospective chart review, which was conducted at 2 sites, 69 patients received treatment with a bipolar radiofrequency device. Out of those 69 patients, 13 patients received bipolar in conjugation with CO2 laser treatment, while 32 patients received monopolar frequency. The study protocol normally consists of three sessions of treatment. Each session was four weeks apart with a whole 6-month duration follow-up. Results were evaluated by urogenital distress inventory (UDI)-6 questionnaire before and after treatment. RESULTS The bipolar group improved UDI-6 scores across time more so than did the monopolar group with some evidence suggesting that the bipolar radiofrequency treatment was more effective compared to the monopolar radiofrequency. Three months after treatment, the bipolar group UDI-6 values were lower than those of the monopolar group. Six months after treatment, the UDI-6 scores increased in both groups, suggesting decrease efficacy with time however, the bipolar group's UDI-6 scores were consistently lower than the monopolar group's scores. CONCLUSION This study shows benefit of both monopolar and bipolar radiofrequency device in patients with stress urinary incontinence and mixed UI, with bipolar RF more efficacious than monopolar RF. More randomized prospective studies are needed to confirm these findings.

Abstract
To describe the clinical response and side effects of radiofrequency treatment in patients with urinary incontinence after radical prostatectomy. This is a phase 1 clinical trial with 10 men up to 65 years of age who had urinary incontinence after radical prostatectomy, post void residual volume < 50 ml verified by ultrasonography, pad test ≥ 1 g, and PSA < 0.2 ng/ml. pad test and self-administered questionnaires were used to assess clinical response. Scales were used to measure treatment satisfaction and improvement in symptoms. Participants underwent five sessions of 2 min of non-ablative endoanal radiofrequency (41 °C). The evaluated co-primary endpoints were urinary incontinence volume and urinary symptoms, analyzed by the Wilcoxon nonparametric test; residual volume, and self-reports to assess safety. The participants' mean age was 57.5 ± 4.9. The initial pad test score was 6.5 g (1.7-50.0) with a final score of 2.0 g (0.0-9.0) (p < 0.01). Ultrasonography showed no alteration of residual volume. A decrease of urinary loss was found in nine patients, three of them showed a complete resolution of urinary loss. A decrease in irritative micturition symptoms was found as well, but no improvement in the quality of life was shown. Regarding treatment satisfaction, two patients were neutral, six satisfied, and two very satisfied. Limitations included pain while the endoanal electrode was inserted. Four patients indicated pain during treatment, but overall results were positive. The reduction of urinary loss and irritative micturition symptoms increased patients' satisfaction scores, without improving their perception of quality of life.

Abstract
Background Fecal Incontinence (FI) can seriously affect quality of life. The treatment of fecal incontinence starts conservatively but in case of failure, different surgical approaches may be proposed to the patient. Recently several not invasive approaches have been developed. One of these is the radiofrequency (RF) energy application to the internal anal sphincter. Case presentation We report a rare case of an anal abscess related to a SECCA procedure in a 66-year-old woman affected by gas and FI for twenty years. Conclusions The complications post-SECCA procedure reported in literature are generally not serious and often self-limited, such as bleeding or anal pain. This is a case of an anal abscess. We suggest that this finding could consolidate the importance of administering antibiotic therapy to patients and to run a full course of at least 6 days rather than a short-term (24 h) therapy, with the aim to minimize the incidence of this complication.

Abstract
PURPOSE To evaluate the clinical response and adverse effects of radiofrequency on the urethral meatus in the treatment of stress urinary incontinence in women. MATERIALS AND METHODS This phase one study included ten women with Stress Urinary Incontinence (SUI). The evaluation consisted of 1 hour Pad tests to quantify urine loss and to assess the degree of procedure satisfaction by using the Likert scale. To evaluate safety, we observed the number of referred side effects. RESULTS Average age was 53.10 years±7.08 years. In assessing the final Pad Test, 70% showed a reduction and 30% a worsening of urinary loss. Using the Pad Test one month later, there was a reduction in all patients (p=0.028). The degree of satisfaction was 90% and no side effects have been observed. One patient reported burning sensation. CONCLUSION The treatment of SUI with radiofrequency on the urethral meatus has no adverse effects, being a low risk method that reduces urinary loss in women. However, to increase the validity of the study, larger clinical trials are warranted.

Abstract
BACKGROUND Fecal incontinence is a common disorder, but its pathophysiology is not completely understood. OBJECTIVE The aim of this review is to present animal models that have a place in the study of fecal incontinence. DATA SOURCES A literature review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines performed in August 2016 revealed 50 articles of interest. Search terms included fecal/faecal incontinence and animal model or specific species. STUDY SELECTION Articles not describing an animal model, in vitro studies, veterinary literature, reviews, and non-English articles were excluded. MAIN OUTCOME MEASURES The articles described models in rats (n = 31), dogs (n = 8), rabbits (n = 7), and pigs (n = 4). RESULTS Different fecal incontinence etiologies were modeled, including anal sphincter lesions (33 articles) ranging from a single anal sphincter cut to destruction of 50% of the anal sphincter by sharp dissection, electrocautery, or diathermy. Neuropathic fecal incontinence (12 articles) was achieved by complete or incomplete pudendal, pelvic, or inferior rectal nerve damage. Mixed fecal incontinence (5 articles) was modeled either by the inflation of pelvic balloons or an array of several lesions including nervous and muscular damage. Anal fistulas (2 articles), anal sphincter resection (3 articles), and diabetic neuropathy (2 articles) were studied to a lesser extent. LIMITATIONS Bias may have arisen from the authors' own work on fecal incontinence and the absence of blinding to the origins of articles. CONCLUSIONS Validated animal models representing the main etiologies of fecal incontinence exist, but no animal model to date represents the whole pathophysiology of fecal incontinence. Therefore, the individual research questions still dictate the choice of model and species.

Abstract
Fecal incontinence is a devastating condition, vastly under-reported, and may affect up to 18% of the population. While conservative management may be efficacious in a large portion of patients, those who are refractory will likely benefit from appropriate surgical intervention. There are a wide variety of surgical approaches to fecal incontinence management, and knowledge and experience are crucial to choosing the appropriate procedure and maximizing functional outcome while minimizing risk. In this article, we provide a comprehensive description of surgical options for fecal incontinence to help the clinician identify an appropriate intervention.

Faecal incontinence, defined as the involuntary loss of solid or liquid stool, is a common problem affecting 0.8-8.3% of the adult population. Individuals suffering from faecal incontinence often live a restricted life with reduced quality of life. The present paper is a clinically oriented review of the pathophysiology, evaluation and treatment of faecal incontinence. First-line therapy should be conservative and usually include dietary adjustments, fibre supplement, constipating agents or mini enemas. Biofeedback therapy to improve external anal sphincter function can be offered but the evidence for long-term effect is poor. There is good evidence that colonic irrigation can reduce symptoms and improve quality of life, especially in patients with neurogenic faecal incontinence. Surgical interventions should only be considered if conservative measures fail. Sacral nerve stimulation is a minimally invasive procedure with high rate of success. Advanced surgical procedures should be restricted to highly selected patients and only performed at specialist centres. A stoma should be considered if other treatment modalities fail.
