Abstract
BACKGROUND Faecal incontinence (FI) is common, with a significant impact on quality of life. Percutaneous tibial nerve stimulation (PTNS) is a therapy for FI; however, its role has recently been questioned. Here we report the short-term clinical and manometric outcomes in a large tertiary centre. METHODS A retrospective review of a prospective PTNS database was performed, extracting patient-reported FI outcome measures including bowel diary, the St Marks's Incontinence Score (SMIS) and Manchester Health Questionnaire (MHQ). Successful treatment was > 50% improvement in symptoms, whilst a partial response was 25-50% improvement. High-resolution anorectal manometry (HRAM) results before and after PTNS were recorded. RESULTS Data were available from 135 patients [119 (88%) females; median age: 60 years (range: 27-82years)]. Overall, patients reported a reduction in urge FI (2.5-1) and passive FI episodes (2-1.5; p < 0.05) alongside a reduction in SMIS (16.5-14) and MHQ (517.5-460.0; p < 0.001). Some 76 (56%) patients reported success, whilst a further 20 (15%) reported a partial response. There were statistically significant reductions in rectal balloon thresholds and an increase in incremental squeeze pressure; however, these changes were independent of treatment success. CONCLUSION Patients report PTNS improves FI symptoms in the short term. Despite this improvement, changes in HRAM parameters were independent of this success. HRAM may be unable to measure the clinical effect of PTNS, or there remains the possibility of a placebo effect. Further work is required to define the role of PTNS in the treatment of FI.

Luo C, Wei D, Pang K, Mei L, Chen Y, Niu X. Is percutaneous tibial nerve stimulation (PTNS) effective for fecal incontinence (FI) in adults compared with sham electrical stimulation? A meta-analysis. Tech Coloproctol 2024; 28:37. [PMID: 38401006 DOI: 10.1007/s10151-024-02910-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 01/27/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND Sacral nerve neuromodulation (SNM) has been considered the optimal second-line treatment for fecal incontinence (FI). However, SNM involves high cost and requires highly skilled operators. Percutaneous tibial nerve stimulation (PTNS) has emerged as an alternative treatment modality for FI, yielding varying clinical outcomes. We conducted this meta-analysis to evaluate the effectiveness and safety of PTNS compared to sham electrical stimulation for FI. METHODS PubMed, Embase, Web of Science, and the Cochrane Library were searched for studies from May 12, 2012 to May 12, 2022. RESULTS Four randomized controlled studies were included in this review, involving a total of 439 adult patients with FI (300 in the PTNS group and 194 in the sham electrical stimulation group). Our meta-analysis revealed that PTNS demonstrated superior efficacy in reducing weekly episodes of FI compared to the control groups (MD - 1.6, 95% CI - 2.94 to - 0.26, p = 0.02, I2 = 30%). Furthermore, a greater proportion of patients in the PTNS group reported more than a 50% reduction in FI episodes per week (RR 0.73, 95% CI 0.57-0.94, p = 0.02, I2 = 6%). However, no significant differences were observed in any domains of the FI Quality of Life (QoL) and St Mark's incontinence scores (MD - 2.41, 95% CI - 5.1 to 0.27, p = 0.08, I2 = 67%). Importantly, no severe adverse events related to PTNS were reported in any of the participants. CONCLUSIONS Our meta-analysis revealed that PTNS was more effective than sham stimulation in reducing FI episodes and led to a higher proportion of patients reporting more than a 50% reduction in weekly FI episodes.

Abstract
Introduction Faecal incontinence (FI) is a common condition with a significant impact on quality of life (QoL). Neuromodulation treatments delivered by members of the multidisciplinary team including sacral nerve stimulation (SNS) and percutaneous tibial nerve stimulation (PTNS) are options for FI refractory to conservative management. The aim of this study was to assess whether a successful treatment with one neuromodulation modality corresponds with success in the other. Methods A retrospective review of a prospectively managed neuromodulation database identified 15 patients who had undergone both PTNS and SNS. The definition of success of each treatment was a >50% improvement in any of The St. Mark's Incontinence Score, Manchester Health Questionnaire, or weekly faecal urgency or FI episodes. Results Complete data from 12 patients was available for assessment and PTNS was delivered as the first treatment in nine patients. Overall, seven patients (58%) had successful PTNS treatment, with 10 (83%) having a successful SNS trials. Of the seven patients who had successful PTNS treatment, six patients (85.4%) went on to have success with SNS. Of the five patients who failed PTNS, four (80%) went on to have SNS success. Five (71%) of those who had positive PTNS outcomes had permanent SNS implantation as their final treatment decision. Conclusion This study suggests that there is no clear relationship between successful PTNS treatment and an SNS trial period which may be explained by differing mechanisms of action or the potential placebo effect of PTNS. Further work is required to investigate any association in larger studies to inform clinical practice.

Abstract
BACKGROUND Posterior tibial nerve stimulation (PTNS) is a minimally invasive approach with little adverse effects, but obtaining good results as shown in the different scales for the evaluation of the severity of incontinence. The aim of this study was to determine the effects of PTNS based on manometric determinations of the anal sphincter and severity during a period of treatment of 6 months (18 sessions). PATIENTS AND METHODS A prospective interventional study of patients with fecal incontinence was performed. Subjects underwent one 30-min session every week for 12 weeks, followed by 6 sessions every 2 weeks. The effect on incontinence was evaluated by means of St. Marks and defecatory urgency scales, and manometry. RESULTS Seventy-three patients were included. At baseline, 28.8% of the patients had a retention time of less than 1 min. At 12 weeks, 39.7% of the patients presented a retention time to 5-10 min and at 18 weeks 37% presented it over 10 min. At baseline, mean St Marks score was 15.1 + 5.1, improving after 12 weeks of treatment to 8.9 + 5 (p < 0.001). After 18 sessions, a greater improvement was observed up to 4 + 4.8 (p < 0.001). Maximum resting pressure showed a significant increase after treatment (mean increase 9.8 mmHg; p = 0.006). Similarly, maximum squeeze pressure also presented a significant augmentation (mean increase 25.3 mmHg; p = 0.002). CONCLUSION Eighteen sessions of PTNS, divided in 12 weekly sessions and 6 sessions every 2 weeks, have shown to obtain benefits, reducing the St. Marks and the defecatory urgency scores, and increasing the manometric values.

Abstract
BACKGROUND/AIMS Fecal incontinence (FI) is a common, debilitating condition that causes major impact on quality of life for those affected. Non-surgical treatment options include anorectal biofeedback therapy (BF) and percutaneous tibial nerve stimulation (PTNS), usually performed separately. The aims of the current study were to determine the feasibility, tolerability, safety, and efficacy of performing a combined BF and PTNS treatment protocol. METHODS Female patients with urge FI were offered a novel pilot program combining BF with PTNS. The treatment protocol consisted of 13 weekly sessions: an educational session, followed by 5 combined BF and PTNS sessions, 6 PTNS and a final combined session. Anorectal physiology and clinical outcomes were assessed throughout the program. For efficacy, patients were compared with BF only historical FI patients matched for age, parity, and severity of symptoms. RESULTS A total of 12/13 (93%) patients completed the full program. Overall attendance rate was 93% (157/169 sessions). Patient comfort score with treatment was rated high at 9.8/10 (SD 0.7) for PTNS and 8.6/10 (SD 1.7) for the BF component. No major side effects were reported. A reduction of at least 50% in FI episodes/week was achieved by 58% of patients by visit 6, and 92% by visit 13. No physiology changes were evident immediately following PTNS compared with before, but pressure during sustained anal squeeze improved by the end of the treatment course. Comparing outcomes with historical matched controls, reductions in weekly FI episodes were more pronounced in the BF only group at visit 6, but not week 13. CONCLUSIONS In this pilot study, concurrent PTNS and anorectal biofeedback therapy has been shown to be feasible, comfortable, and low risk. The combined protocol is likely to be an effective treatment for FI, but future research could focus on optimizing patient selection.
