Park CK, Wang L, Koppen IJK, Alpert SA, Diefenbach KA, Wood RJ, Bali N, Vaz K, Yacob D, Di Lorenzo C, Lu PL. Sacral nerve stimulation leads to long-term improvement in fecal incontinence and quality of life for children with functional and organic defecation disorders. Neurogastroenterol Motil 2024; 36:e14865. [PMID: 39005152 DOI: 10.1111/nmo.14865] [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: 01/31/2023] [Revised: 06/24/2024] [Accepted: 07/02/2024] [Indexed: 07/16/2024]
Abstract
BACKGROUND Our objective was to evaluate long-term outcomes of sacral nerve stimulation (SNS) for children with functional and organic defecation disorders. METHODS We performed a prospective study of children <21 years of age who started SNS treatment between 2012 and 2018. We recorded demographics, medical history, and diagnostic testing. We obtained measures of symptom severity and quality of life at baseline and follow up at 1, 6, 12, 24, 36, 48, and ≥60 months. Successful response was defined as bowel movements >2 times/week and fecal incontinence (FI) <1 time/week. Families were contacted to administer the Glasgow Children's Benefit Inventory and to evaluate patient satisfaction. KEY RESULTS We included 65 patients (59% female, median age at SNS 14 years, range 9-21) with median follow-up of 32 months. Thirty patients had functional constipation (FC), 15 had non-retentive FI (NRFI), and 16 had an anorectal malformation (ARM). The percentage with FI <1 time/week improved from 30% at baseline to 64% at 1 year (p < 0.001) and 77% at most recent follow-up (p < 0.001). Patients with FC, NRFI, and ARM had sustained improvement in FI (p = 0.02, p < 0.001, p = 0.02). Patients also reported fewer hard stools (p = 0.001). Bowel movement frequency did not improve after SNS. At most recent follow-up, 77% of patients with a functional disorder and 50% with an organic disorder had responded (p = 0.03). Nearly all families reported benefit. CONCLUSIONS AND INFERENCES SNS led to sustained improvement in FI regardless of underlying etiology, but children with functional disorders were more likely to respond than those with organic disorders.

Abstract
BACKGROUND Anorectal motility disorders such as dyssynergic defecation (DD), faecal incontinence (FI) and anorectal pain affect 40% of the population and are a frequent reason for gastroenterology consultation. They significantly affect the quality of life and lead to psychological distress. Lack of understanding of these problems compounded by a lack of availability and knowledge of diagnostic tools in most medical centres and/or trained physicians has significantly hampered this field. AIMS To discuss the latest advances in pathophysiology, diagnostic tests and therapeutic options for these disorders using an evidence-based approach. METHODS We reviewed the published literature over the past 20 years on DD, FI and anorectal pain and distilled these into a narrative review. RESULTS A detailed history, prospective stool diary and digital rectal exam, together with diagnostic tests such as anorectal manometry, balloon expulsion test, translumbosacral anorectal magnetic stimulation test for assessing neuropathy, defecography and anal ultrasound, can provide detailed mechanistic and structural information. Such knowledge can pave the way for a meaningful and pathophysiologic-based management approach. This could include biofeedback therapy for DD or FI, sensory training for rectal hyposensitivity or sensory adaptation training for rectal hypersensitivity or sphincter bulking agents or neuromodulation therapies. These treatments are effective and safe. CONCLUSIONS Anorectal motility disorders are common, but either less well recognized or poorly managed by most gastroenterologists. Equipped with the practical and up-to-date knowledge provided in this review, physicians could provide improved health care for these patients.

Long-term Outcomes of Sacral Nerve Stimulation on the Treatment of Fecal Incontinence: A Systematic Review. Neuromodulation 2024:S1094-7159(24)00649-4. [PMID: 39152989 DOI: 10.1016/j.neurom.2024.06.504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 06/06/2024] [Accepted: 06/24/2024] [Indexed: 08/19/2024]
Abstract
INTRODUCTION Sacral nerve stimulation (SNS) has now been used as a treatment for fecal incontinence (FI) for >20 years. The aim of this systematic review was to determine the long-term efficacy of SNS on the treatment of FI. MATERIALS AND METHODS A comprehensive search of the MEDLINE, Embase, and Cochrane Central data bases was performed to find publications, excluding case reports, reporting outcomes of SNS treatment for FI in adults with ≥36 months of follow-up. Bias was assessed using the Risk of Bias in Non-randomized Studies-of Interventions tool. Data were summarized per reported FI-related outcomes for symptom severity and quality of life. RESULTS In total, 3326 publications were identified, and 36 studies containing 3770 subjects were included. All studies had a serious risk of bias. Success was variably defined by each publication and ranged from 59.4% to 87.5% for per-protocol analyses and 20.9% to 87.5% for intention-to-treat analyses. All studies reporting bowel diary data, St Mark's scores, and Cleveland Clinic Incontinence Scores indicated significant improvement with SNS treatment in the long term. Studies that evaluated quality-of-life outcomes also all showed improvements in quality of life as measured by the Fecal Incontinence Quality of Life Scale. The aggregate revision rate was 35.2%, and the explantation rate was 19.7%. CONCLUSIONS Improvements in objective and subjective outcomes at ≥36 months support using SNS for the long-term treatment of FI. Interpretation of these data is limited by a lack of comparative trials and heterogeneity of the included studies.

Abstract
BACKGROUND Electrical stimulation of the gut has been investigated in recent decades with a view to treating various gastro-intestinal motility disorders including, among others, gastric electrical stimulation to relieve nausea and vomiting associated with gastroparesis and sacral neuromodulation to treat fecal incontinence and/or constipation. Although their symptomatic efficacy has been ascertained by randomized controlled trials, their mechanisms of action are not fully understood. PURPOSE This review summarizes the past year's literature on the mechanisms of action of gut electrical stimulation therapies, including their impact on the gut-brain axis.

Lancet Gastroenterol Hepatol 2024; 9:147-158. [PMID: 38128556 DOI: 10.1016/s2468-1253(23)00332-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 09/25/2023] [Accepted: 09/27/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Non-randomised studies assessing intrarectal botulinum toxin type A (BoNTA) injections for faecal incontinence are promising. We aimed to evaluate the efficacy of BoNTA for the treatment of faecal incontinence in a randomised study. METHODS In this randomised, double-blind, placebo-controlled study, we included adult patients who had at least one urgency or faecal incontinence episode per week for at least 3 months and who had experienced a failure of conservative or surgical treatment from eight French specialist hospital units with the skills to manage patients with faecal incontinence. Patients were randomly assigned (1:1) by a central web form to receive intrarectal submucosal injections of either 200 units of BoNTA (Botox; Allergan, Irvine, CA, USA; BoNTA group) or an equivalent volume of saline (placebo group), stratified by Cleveland Clinic Severity scores (CCS score; ≥12 or <12). Patients, investigators, study site staff, and sponsor personnel were masked to treatment allocation up to the 6-month visit. The primary endpoint was the number of episodes of faecal incontinence and urgency per day assessed using 21-day patient bowel diaries 3 months after the treatment. The primary analysis was performed using a modified intention-to-treat (mITT) approach (ie, in all the randomised patients who had received a treatment) with adjustment for baseline faecal incontinence and urgency episodes. After the final data collection at 6 months after injections, patients were unmasked and offered the BoNTA treatment if they were in the placebo group (rescue therapy) without masking, with an additional 6 months of safety follow-up. This trial is registered with ClinicalTrials.gov, number NCT02414425. FINDINGS Between Nov 25, 2015, and Nov 25, 2020, we randomly assigned 200 patients to receive either BoNTA (n=100) or placebo (n=100) injections. Due to withdrawals before the injections, 96 patients were included in the BoNTA group and 95 patients were included in the placebo group (mITT analysis). The mean number of faecal incontinence and urgency episodes per day in the BoNTA group decreased from 1·9 (SD 2·2) at baseline to 0·8 (1·8) at 3 months after the injections, and from 1·4 (1·1) to 1·0 (1·0) in the placebo group, with a baseline-adjusted mean group difference at 3 months estimated at -0·51 (95% CI -0·80 to -0·21, p=0·0008). No serious treatment-related adverse events were reported in the trial. The most frequently reported non-serious adverse event (treatment related or not) following the BoNTA or placebo injections was constipation (reported in 68 [40%] of 169 patients who received the BoNTA injections and 38 [40%] of 95 patients who received placebo injections). INTERPRETATION BoNTA injections are an efficacious treatment for urge faecal incontinence. Further research will define the optimum selection criteria, dose, site of injection, re-injection frequency, and long-term results.

Abstract
PURPOSE OF REVIEW To provide an updated overview on use of electrostimulation in gastrointestinal motility disorders and obesity, with a focus on gastric electrical stimulation, vagal nerve stimulation and sacral nerve stimulation. RECENT FINDINGS Recent studies on gastric electrical stimulation for chronic vomiting showed a decrease in frequency of vomiting, but without significant improvement in quality of life. Percutaneous vagal nerve stimulation shows some promise for both symptoms of gastroparesis and IBS. Sacral nerve stimulation does not appear effective for constipation. Studies of electroceuticals for treatment of obesity have quite varied results with less clinical penetrance of the technology. Results of studies on the efficacy of electroceuticals have been variable depending on pathology but this area remains promising. Improved mechanistic understanding, technology and more controlled trials will be helpful to establish a clearer role for electrostimulation in treatment of various GI disorders.

Abstract
INTRODUCTION The goal of this project was to create an up-to-date joint European clinical practice guideline for the diagnosis and treatment of faecal incontinence (FI), using the best available evidence. These guidelines are intended to help guide all medical professionals treating adult patients with FI (e.g., general practitioners, surgeons, gastroenterologists, other healthcare workers) and any patients who are interested in information regarding the diagnosis and management of FI. METHODS These guidelines have been created in cooperation with members from the United European Gastroenterology (UEG), European Society of Coloproctology (ESCP), European Society of Neurogastroenterology and Motility (ESNM) and the European Society for Primary Care Gastroenterology (ESPCG). These members made up the guideline development group (GDG). Additionally, a patient advisory board (PAB) was created to reflect and comment on the draft guidelines from a patient perspective. Relevant review questions were established by the GDG along with a set of outcomes most important for decision making. A systematic literature search was performed using these review questions and outcomes as a framework. For each predefined review question, the study or studies with the highest level of study design were included. If evidence of a higher-level study design was available, no lower level of evidence was sought or included. Data from the studies were extracted by two reviewers for each predefined important outcome within each review question. Where possible, forest plots were created. After summarising the results for each review question, a systematic quality assessment using the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) approach was performed. For each review question, we assessed the quality of evidence for every predetermined important outcome. After evidence review and quality assessment were completed, recommendations could be formulated. The wording used for each recommendation was dependent on the level of quality of evidence. Lower levels of evidence resulted in weaker recommendations and higher levels of evidence resulted in stronger recommendations. Recommendations were discussed within the GDG to reach consensus. RESULTS These guidelines contain 45 recommendations on the classification, diagnosis and management of FI in adult patients. CONCLUSION These multidisciplinary European guidelines provide an up-to-date comprehensive evidence-based framework with recommendations on the diagnosis and management of adult patients who suffer from FI.

Abstract
Fecal incontinence (FI) is defined as the involuntary loss or passage of solid or liquid stool in patients. FI is a common and debilitating condition in men and women. The incidence increases with age and also often goes unreported to health care providers. It is crucial that providers ask at-risk patients about possible symptoms. Evaluation and management is tailored to specific symptoms and characteristics of the incontinence. If conservative methods fail to improve symptoms, then other surgical options are considered, such as sacral nerve stimulation and anal sphincter augmentation. This review provides an update on current and future therapies.

Abstract
Fecal incontinence (FI) is a complex often multifactorial functional disorder which is associated with a significant impact on patients’ quality of life. There is a broad spectrum of symptoms, and degrees of severity and diverse patient backgrounds. Several treatment algorithms from different professional societies and experts are available in the literature. However, no consensus has been reached on several aspects of FI management. We performed a critical review of the most recently published guidelines on FI, emphasising the lack of consensus, highlighting specific topics mentioned in each of the guidelines that are not covered in the others and defining the treatment proposed in different clinical scenarios.

Abstract
Sacral neuromodulation (SNM) has been available in the United States for more than 20 years and is a guideline-recommended therapy by both the American Urological Association and the American Society of Colon and Rectal Surgeons, with proven long-term success for urinary urgency incontinence, urinary urgency frequency, nonobstructive urinary retention, and fecal incontinence. Initially the therapy involved a more invasive surgical approach that included a large cut down over the sacrum. This article reviews recent advancements in SNM therapy including updates in best practices for implant technique, technological innovations, and the new clinical literature relevant to contemporary practice.

Abstract
AIM The aim of this work was to evaluate the effectiveness, patient satisfaction and quality of life (QoL) and the safety of sacral neuromodulation (SNM) with the InterStimTM system for the treatment of faecal incontinence (FI) and establish whether results published predominantly by expert sites are generalisable. METHOD This is a prospective, multicentre, observational study that invited all French sites treating FI with the InterStim™ system to enrol subjects indicated for an SNM therapy evaluation. Data were collected at three follow-up visits within 1 and 15 months. Therapeutic effectiveness was evaluated by the reduction in leakages per week and improvements over time in the ability to defer defaecation and QoL (as measured with the Faecal Incontinence Quality of Life score). Safety was assessed through reported adverse events. RESULTS A total of 221 subjects with a mean age of 62.1 years were tested (184 women) and 178 received a permanent implant. For all implanted subjects with diary data at baseline and follow-up, a reduction in leakage of more than 50% was observed in 80%, 76% and 83% at 1-3, 4-8 and 9-15 months, respectively. The mean number of leakage episodes and urgency improved significantly compared with the baseline (p < 0.0001). Subjects showed improvements in QoL and time to defer defaecation and were generally satisfied with their therapy. The main device-related adverse event was the requirement to undertake reprogramming (in 52% of subjects with actions following an event). The rates of infection (in 6% of subjects) and surgical revision (in 10% of subjects) were in agreement with literature reports. CONCLUSION This study confirms the clinical effectiveness, safety and positive effect of SNM on QoL as well as high patient satisfaction for the treatment of FI in real-life.

The effect of colonic tissue electrical stimulation and celiac branch of the abdominal vagus nerve neuromodulation on colonic motility in anesthetized pigs. Neurogastroenterol Motil 2020; 32:e13925. [PMID: 32578346 PMCID: PMC7606494 DOI: 10.1111/nmo.13925] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Revised: 04/20/2020] [Accepted: 05/27/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Knowledge on optimal electrical stimulation (ES) modalities and region-specific functional effects of colonic neuromodulation is lacking. We aimed to map the regional colonic motility in response to ES of (a) the colonic tissue and (b) celiac branch of the abdominal vagus nerve (CBVN) in an anesthetized porcine model. METHODS In male Yucatan pigs, direct ES (10 Hz, 2 ms, 15 mA) of proximal (pC), transverse (tC), or distal (dC) colon was done using planar flexible multi-electrode array panels and CBVN ES (2 Hz, 0.3-4 ms, 5 mA) using pulse train (PT), continuous (10 min), or square-wave (SW) modalities, with or without afferent nerve block (200 Hz, 0.1 ms, 2 mA). The regional luminal manometric changes were quantified as area under the curve of contractions (AUC) and luminal pressure maps generated. Contractions frequency power spectral analysis was performed. Contraction propagation was assessed using video animation of motility changes. KEY RESULTS Direct colon ES caused visible local circular (pC, tC) or longitudinal (dC) muscle contractions and increased luminal pressure AUC in pC, tC, and dC (143.0 ± 40.7%, 135.8 ± 59.7%, and 142.0 ± 62%, respectively). The colon displayed prominent phasic pressure frequencies ranging from 1 to 12 cpm. Direct pC and tC ES increased the dominant contraction frequency band (1-6 cpm) power locally. Pulse train CBVN ES (2 Hz, 4 ms, 5 mA) triggered pancolonic contractions, reduced by concurrent afferent block. Colon contractions propagated both orally and aborally in short distances. CONCLUSION AND INFERENCES In anesthetized pigs, the dominant contraction frequency band is 1-6 cpm. Direct colonic ES causes primarily local contractions. The CBVN ES-induced pancolonic contractions involve central neural network.

Abstract
OBJECTIVE The aim of this study was to assess the effectiveness of sacral nerve modulation (SNM) in a large cohort of patients implanted for at least 10 years, quantify adverse event rates, and identify predictive factors of long-term success. SUMMARY BACKGROUND DATA Few studies have evaluated the long-term success of SNM. METHODS Data collected prospectively from patients implanted for fecal incontinence (FI) in 7 French centers between January 1998 and December 2008 were retrospectively analyzed. Patient FI severity scores were assessed before and 10 years after implantation. The main evaluation criterion was the success of SNM defined by the continuation of the treatment without additional therapies. The secondary evaluation criteria were the rate of device revisions and explantations. Preoperative predictors of success at 10 years were sought. RESULTS Of the 360 patients (27 males, mean age: 59 ± 12 years) implanted for FI, 162 (45%) had a favorable outcome 10 years post-implantation, 115 (31.9%) failed, and 83 (23.1%) were lost to follow-up. The favorable outcome derived from the time-to-event Kaplan-Meier curve at 10 years was 0.64 (95% CI 0.58-0.69). FI severity scores were significantly better 10 years post-implantation compared to preimplantation (7.4 ± 4.3 vs 14.0 ± 3.2; P < 0.0001). During the 10-year follow-up, 233 patients (64.7%) had a surgical revision and 94 (26.1%) were explanted. A history of surgery for FI and sex (male) were associated with an increased risk of an unfavorable outcome. CONCLUSIONS Long-term efficacy was maintained in approximately half of the FI patients treated by SNM at least 10 years post-implantation.

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.

Abstract
The purpose of this study was to determine effects and mechanisms of sacral nerve stimulation (SNS) on visceral hypersensitivity in rodent models of colonic hypersensitivity. SNS was performed with different sets of parameters for 30 min in six regular rats. Visceral sensitivity was assessed by the measurement of electromyogram and abdominal withdrawal reflex before and after SNS. Real/sham SNS with optimized parameters was performed in 8 restraint stress-induced visceral hypersensitivity rats and 10 neonatal acetic acid-treated colonic hypersensitivity rats; acute effect of SNS was assessed by comparing electromyogram and heart rate variability. Neonatal acetic acid-treated rats were treated by SNS (n = 10) or sham-SNS (n = 10) daily for seven days for the assessment of the chronic effect of SNS. (1) When the stimulation amplitude was reduced from 90% of motor threshold to 65% or 40% motor threshold, SNS with certain parameters showed an inhibitory effect on abdominal withdrawal reflex. The best stimulation parameters for SNS were “14 Hz, 330 µs, and 40% motor threshold.” (2) SNS significantly reduced visceral hypersensitivity and improved autonomic function in restraint stress-induced rats. The inhibitory effect was blocked by naloxone. (3)Acute and chronic SNS significantly reduced visceral hypersensitivity and improved autonomic function in acetic acid-treated rats. SNS with reduced stimulation strength may be used to treat colonic hypersensitivity and the best stimulation parameters seem to be “14 Hz, 330 µs and 40% motor threshold”. SNS with optimized parameters improved visceral hypersensitivity in rodent models of colonic hypersensitivity mediated via the autonomic and opioid mechanisms.

Neuromodulation 2019; 23:1108-1116. [PMID: 31889364 DOI: 10.1111/ner.13092] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 11/26/2019] [Accepted: 11/26/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND Successful treatments following electrical nerve stimulation have been commonly reported in patients with fecal incontinence and constipation. However, many of these nerve stimulation trials have not implemented sham controls, and are, therefore, unable to differentiate overall treatment responses from placebo. This systematic review aimed to quantify placebo effects and responses following sham electrical nerve stimulation in patients with fecal incontinence and constipation. MATERIAL AND METHODS A literature search of Ovid MEDLINE, PubMed, EMBASE, and Cochrane databases was conducted from inception to April 2017. Randomized sham-controlled trials investigating the effect of lower gastrointestinal electrical nerve stimulation in fecal incontinence and constipation were included. Pediatric and non-sham controlled trials were excluded. RESULTS Ten randomized sham-controlled trials were included. Sham stimulation resulted in improvements in fecal incontinence episodes by 1.3 episodes per week (95% CI -2.53 to -0.01, p = 0.05), fecal urgency by 1.5 episodes per week (CI -3.32 to 0.25, p = 0.09), and Cleveland Clinic Severity scores by 2.2 points (CI 1.01 to 3.36, p = 0.0003). Sham also improved symptoms of constipation with improved stool frequency (1.3 episodes per week, CI 1.16 to 1.42, p < 0.00001), Wexner Constipation scores (5.0 points, CI -7.45 to -2.54 p < 0.0001), and Gastrointestinal Quality of Life scores (7.9 points, CI -0.46 to 16.18, p = 0.06). CONCLUSIONS Sham stimulation is associated with clinical and statistically meaningful improvements in symptoms of fecal incontinence and constipation, as well as quality of life scores, highlighting the importance of sham controls in nerve stimulation trials. Noncontrolled studies should be interpreted with caution.

Abstract
BACKGROUND Although numerous treatments exist for fecal incontinence (FI), no consensus exists on the best treatment strategy. The aim was to review the literature and to compare the clinical outcomes and effectiveness of treatments available for FI. MATERIALS AND METHOD A systematic literature review was performed, from inception to May 2018, of the following databases: MEDLINE, EMBASE, Science Citation Index Expanded, Cochrane Library. The search terms used were "faecal incontinence" and "treatment". Only randomized controlled trials (RCTs) comparing treatments for FI were considered. A Bayesian network meta-analysis was performed using the Markov chain Monte Carlo method. RESULT Forty-seven RCTs were included comparing 37 treatments and reporting on 3748 participants. No treatment ranked best or worst with high probability for any outcome of interest. No significant difference was identified between treatments for frequency of FI per week, or in changing the resting pressure, maximum resting pressure, squeeze pressure, and maximum squeeze pressure. Radiofrequency resulted in more adverse events compared to placebo. Sacral nerve stimulation (SNS) and zinc-aluminium improved the fecal incontinence quality of life questionnaire (FIQL) lifestyle, coping, and embarrassment domains compared to placebo. Transcutaneous posterior tibial nerve stimulation (TPTNS) improved the FIQL embarrassment domain compared to placebo. Autologous myoblasts and zinc-aluminium improved the FIQL depression domain compared to placebo. SNS, artificial bowel sphincter (ABS), and zinc-aluminium significantly improved incontinence scores compared to placebo. Injection of non-animal stabilized hyaluronic acid/dextranomer (NASHA/Dx) resulted in more patients with ≥50% reduction in FI episodes compared to placebo. CONCLUSION SNS, ABS, TPTNS, NASHA/Dx, zinc-aluminium, and autologous myoblasts resulted in isolated improvements in specific outcomes of interest. No difference was identified in incontinence episodes, no treatment ranked best persistently or persistently improved outcomes, and many included treatments did not significantly benefit patients compared to placebo. Large multicentre RCTs with long-term follow-up and standardized inclusion criteria and outcome measures are needed.

Abstract
AIM To perform a review of the literature reporting on randomised controlled trials (RCTs) comparing treatments for faecal incontinence (FI) in adults. METHODS A literature search of MEDLINE, Embase, Science Citation Index Expanded and Cochrane was performed in order to identify RCTs reporting on treatments for FI. RESULTS The review included 60 RCTs reporting on 4838 patients with a mean age ranging from 36.8 to 88 years. From the included RCTs, 32 did not identify a significant difference between the treatments compared. Contradictory results were identified in RCTs comparing percutaneous posterior tibial nerve stimulation and transcutaneous tibial nerve stimulation versus sham stimulation, biofeedback-pelvic floor muscle training (BF-PFMT) versus PFMT, and between bulking agents such as PTQTM versus Durasphere®. In two separate RCTs, combination treatment of amplitude-modulated medium frequency stimulation and electromyography-biofeedback (EMG-BF), was noted to be superior to EMG-BF and low-frequency electrical stimulation alone. Combination of non-surgical treatments such as BF with sphincteroplasty significantly improved continence scores compared to sphincteroplasty alone. Surgical treatments were associated with higher rates of serious adverse events compared to non-surgical interventions. CONCLUSIONS The current evidence has not identified significant differences between treatments for FI, and where differences were identified, the results were contradictory between RCTs.

Abstract
Sacral nerve stimulation (SNS) is an established treatment for faecal incontinence involving the implantation of a quadripolar electrode into a sacral foramen, through which an electrical stimulus is applied. Little is known about the induced spread of electric current around the SNS electrode and its effect on adjacent tissues, which limits optimisation of this treatment. The authors constructed a 3-dimensional imaging based finite element model in order to calculate and visualise the stimulation induced current and coupled this to biophysical models of nerve fibres. They investigated the impact of tissue inhomogeneity, electrode model choice and contact configuration and found a number of effects. (i) The presence of anatomical detail changes the estimate of stimulation effects in size and shape. (ii) The difference between the two models of electrodes is minimal for electrode contacts of the same length. (iii) Surprisingly, in this arrangement of electrode and neural fibre, monopolar and bipolar stimulation induce a similar effect. (iv) Interestingly when the active contact is larger, the volume of tissue activated reduces. This work establishes a protocol to better understand both therapeutic and adverse stimulation effects and in the future will enable patient-specific adjustments of stimulation parameters.

Abstract
AIMS Spina Bifida (SB) is a rare congenital condition that frequently impairs the neurological control of both fecal continence and defecation. Several therapeutic strategies have been proposed but impact assessment is lacking. Our objectives were to quantify the symptomatic improvement and to determine the optimal strategy in this rare condition where randomized controlled trials are difficult to conduct. METHODS Data were extracted from a prospective database. The present analysis focused on patients having undergone at least two gastroenterological assessments. A standardized therapeutic approach was used from the first visit. Improvement was quantified by the variation of quantified symptomatic scores. RESULTS The data of of 57 adults with SB (gender F/M: 30/27 [52.6/47.4%]; mean age: 33.8 [18.5] years) were extracted. After a mean follow-up of 46 months, 23/57 patients (40.4%) had at least improvement of one point of the Cleveland Clinic Incontinence score (CCIS); 13/57 (22.8%) reported a significant improvement of continence (delta score >50%). Five of the twelve patients (41.6%) with CCIS < 5 at baseline became incontinent over time. The neurological level was not associated with a worse continence outcome. Work on stool consistency and transanal irrigation were the most useful strategies in those with significant improvement of continence. CONCLUSIONS Using conventional strategies, a benefit on fecal continence occurs in only one out of five patients suffering from Spina Bifida and continent patients at baseline can develop fecal incontinence over time. A strategy targeting improved control of defecation (transanal irrigation) and a standardization of follow-up protocol might be beneficial.

Neuromodulation 2018; 22:690-696. [PMID: 30346640 DOI: 10.1111/ner.12870] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2018] [Revised: 08/23/2018] [Accepted: 08/23/2018] [Indexed: 12/30/2022]
Abstract
OBJECTIVES Sacral nerve stimulation (SNS) is a surgical treatment of urinary and fecal incontinence. Despite its clinical efficacy, the mechanisms of action of SNS are still poorly known. This may be related to the use of acute stimulation models. Up to date, no rodent model of chronic SNS implants has been developed. Therefore, the aim of this study was to create a fully implantable and remotely controllable stimulating device to establish an animal model of chronic SNS. MATERIALS AND METHODS The stimulating device consisted of an implantable pulse generator linked to a platinum electrode. The communication with the device was made through an inductive link which allowed to adjust the stimulation parameters; that is, to turn the device on and off or check the battery status remotely. Rats underwent two surgical procedures. In the first procedure, we achieved chronic sacral stimulation but the implanted electrode was not fixated. In the second procedure, the electrode was fixated in the sacral foramen using dental resin. In both cases, the correct positioning of the electrode was evaluated by computed tomography (CT) imaging and the presence of tail tremor in response to high intensity stimulation. We only tested the function of implanted electrode with fixation using micturition frequency assessment following bipolar or unipolar SNS for three days after recovery. RESULTS CT imaging showed that implantation of the electrode required fixation as we found that the second surgical procedure yielded a more precise placement of the implanted electrode. The correct placement of implanted electrode observed with imaging was always correlated with a successful tail tremor response in rats, therefore we pursued our next experiments with the second surgical procedure and only assessed the tail tremor response. We found that both bipolar and unipolar SNS reduced micturition frequency. CONCLUSION This stimulating device provides an efficient method to perform chronic SNS studies in rats.

Efficacy and mechanism of sub-sensory sacral (optimised) neuromodulation in adults with faecal incontinence: study protocol for a randomised controlled trial. Trials 2018; 19:336.

Abstract
Background Faecal incontinence (FI) is a substantial health problem with a prevalence of approximately 8% in community-dwelling populations. Sacral neuromodulation (SNM) is considered the first-line surgical treatment option in adults with FI in whom conservative therapies have failed. The clinical efficacy of SNM has never been rigorously determined in a trial setting and the underlying mechanism of action remains unclear. Methods/design The design encompasses a multicentre, randomised, double-blind crossover trial and cohort follow-up study. Ninety participants will be randomised to one of two groups (SNM/SHAM or SHAM/SNM) in an allocation ratio of 1:1. The main inclusion criteria will be adults aged 18–75 years meeting Rome III and ICI definitions of FI, who have failed non-surgical treatments to the UK standard, who have a minimum of eight FI episodes in a 4-week screening period, and who are clinically suitable for SNM. The primary objective is to estimate the clinical efficacy of sub-sensory SNM vs. SHAM at 32 weeks based on the primary outcome of frequency of FI episodes using a 4-week paper diary, using mixed Poisson regression analysis on the intention-to-treat principle. The study is powered (0.9) to detect a 30% reduction in frequency of FI episodes between sub-sensory SNM and SHAM stimulation over a 32-week crossover period. Secondary objectives include: measurement of established and new clinical outcomes after 1 year of therapy using new (2017 published) optimised therapy (with standardised SNM-lead placement); validation of new electronic outcome measures (events) and a device to record them, and identification of potential biological effects of SNM on underlying anorectal afferent neuronal pathophysiology (hypothesis: SNM leads to increased frequency of perceived transient anal sphincter relaxations; improved conscious sensation of defaecatory urge and cortical/subcortical changes in afferent responses to anorectal electrical stimulation (main techniques: high-resolution anorectal manometry and magnetoencephalography). Discussion This trial will determine clinical effect size for sub-sensory chronic electrical stimulation of the sacral innervation. It will provide experimental evidence of modifiable afferent neurophysiology that may aid future patient selection as well as a basic understanding of the pathophysiology of FI.

Abstract
AIMS Percutaneous tibial nerve stimulation (PTNS) and sacral nerve stimulation (SNS) are both second-line treatments for faecal incontinence (FI). To compare the clinical outcomes and effectiveness of SNS versus PTNS for treating FI in adults. METHOD A literature search of MEDLINE, Embase, Science Citation Index Expanded and Cochrane was performed in order to identify studies comparing SNS and PTNS for treating FI. A risk of bias assessment was performed using The Cochrane Collaboration's risk of bias tool. A random effects model was used for the meta-analysis. RESULTS Four studies (one randomised controlled trial and three nonrandomised prospective studies) reported on 302 patients: 109 underwent SNS and 193 underwent PTNS. All included studies noted an improvement in symptoms after treatment, without any significant difference in efficacy between SNS and PTNS. Meta-analysis demonstrated that the Wexner score improved significantly with SNS compared to PTNS (weighted mean difference 2.27; 95% confidence interval 3.42, 1.12; P < 0.01). Moreover, SNS was also associated with a significant reduction in FI episodes per week and a greater improvement in the Fecal Incontinence Quality of Life coping and depression domains, compared to PTNS on short-term follow-up. Only two studies reported on adverse events, reporting no serious adverse events with neither SNS nor PTNS. CONCLUSION Current evidence suggests that SNS results in significantly improved functional outcomes and quality of life compared to PTNS. No serious adverse events were identified with either treatment. Further, high-quality, multi-centre randomised controlled trials with standardised outcome measures and long-term follow-up are required in this field.

Abstract
AIMS Sacral neuromodulation (SNM) is an accepted therapy for a variety of conditions. However, despite over 20 years of experience, it remains a specialized procedure with a number of subtleties. Here we present the recommendations issued from the International Continence Society (ICS) SNM Consensus Panel. METHODS Under the auspices of the ICS, eight urologists, three colorectal surgeons and two urogynecologists, covering a wide breadth of geographic and specialty interest representation, met in January 2017 to discuss best practices for neuromodulation. Suggestions for statements were submitted in advance and specific topics were assigned to committee members, who prepared and presented supporting data to the group, at which time each topic was discussed in depth. Best practice statements were formulated based on available data. This document was then circulated to multiple external reviewers after which final edits were made and approved by the group. RESULTS The present recommendations, based on the most relevant data available in the literature, as well as expert opinion, address a variety of specific and at times problematic issues associated with SNM. These include the use of SNM for a variety of underlying conditions, need for pre-procedural testing, use of staged versus single-stage procedures, screening for success during the trial phase, ideal anesthesia, device implantation, post-procedural management, trouble-shooting loss of device function, and future directions for research. CONCLUSIONS These guidelines undoubtedly constitute a reference document, which will help urologists, gynecologists, and colorectal surgeons optimize their use of SNM for refractory urinary urgency and frequency, UUI, NOR, and FI.

The foreign body response and morphometric changes associated with mesh-style peripheral nerve cuffs. Acta Biomater 2018; 67:79-86.

Abstract
Nerve cuffs have been used to anchor and protect penetrating electrodes in peripheral nerves and have been used as non-penetrating electrodes for neural recording and nerve stimulation. The material of choice for such applications is silicone, an inert synthetic biomaterial which elicits a minimal chronic foreign body response (FBR). While histological studies of solid silicone cuffs are available, to the best of our knowledge a comparison to other cuff designs is not well documented. Here, we describe the FBR and morphological changes that accompany nerve cuff implantation in the rat sciatic nerve by comparing a metallic mesh with and without a parylene coating to one made of silicone. Two months after implantation, we observed that such implants, irrespective of the cuff type, were associated with a persistent inflammatory response consisting of activated macrophages attached to the implant surfaces, which extended into the endoneurial space of the encapsulated nerve. We also observed foreign body giant cells in the epineurial space that were more prevalent in the mesh cohorts. The mesh cuff groups showed significant changes in several morphometric parameters that were not seen in the silicon group including reductions in nerve fiber packing density and a greater reduction of large diameter fibers. High magnification microscopy also showed greater evidence of foamy macrophages in the endoneurial space of the mesh implanted cohorts. Although the precise mechanisms are unknown, the results showed that mesh style nerve cuffs show a greater inflammatory response and had greater reductions in morphometric changes in the underlying nerve compared to silicone in the absence of a penetrating injury. STATEMENT OF SIGNIFICANCE While traditional silicone cuffs have been in use for decades, the inflammatory and morphometric effects of these cuffs on the underlying nerve have not been deeply studied. Further, manipulation of the foreign body response to nerve cuffs by using various materials and/or designs has not been well reported. Therefore, we report the inflammatory response around nerve cuffs of various materials and designs, as well as report morphometric parameters of the underlying nerve. These data provide important information regarding the potential for quantitative morphometric changes associated with the use of nerve cuffs, and, importantly, suggests that these changes are associated with the degree of inflammation associated with the cuff.

Abstract
BACKGROUND There is a paucity of real-world data regarding surgeon utilization of sacral nerve stimulation for fecal incontinence compared with anal sphincteroplasty. OBJECTIVE This study aims to examine trends in sacral nerve stimulation use compared with sphincteroplasty for fecal incontinence and surgeon-level variation in progression to implantation of the pulse generator. DESIGN This is a population-based study. PATIENTS Patients with fecal incontinence between 2011 and 2014 in New York who underwent stage 1 of the sacral nerve stimulation procedure were selected. For the comparison with sphincteroplasty, patients with fecal incontinence who underwent anal sphincteroplasty between 2008 and 2014 were included. MAIN OUTCOME MEASURES The main outcomes after sacral nerve stimulation generator placement were unplanned 30-day admission, emergency department visit within 30 days, revision or explant of leads or generator, and 30-day mortality. RESULTS Six hundred twenty-one patients with fecal incontinence underwent a stage 1 procedure with 79.7% progressing to stage 2. There has been an increase in the number of sacral nerve stimulation cases per year as well as the number of surgeons performing the procedure. The rate of progression to stage 2 among patients treated by colorectal surgeons was 80.2% compared with 77.0% among those treated by noncolorectal surgeons. Among those who completed stage 2, there were 3 (0.5%) unplanned 30-day admissions, 24 (4.4%) emergency department visits within 30 days, and 0 mortalities within 30 days. Thirty-two (6.5%) patients had their leads or pulse generator revised or explanted. There was a significant decrease in annual sphincteroplasty cases and the number of providers performing the procedure starting in 2011. LIMITATIONS We lacked data regarding patient and physician decision making and the severity of disease. CONCLUSIONS Sacral nerve stimulation for fecal incontinence is increasing in popularity with an increasing number of surgeons utilizing sacral nerve stimulation for fecal incontinence rather than sphincteroplasty.

Abstract
AIM Poor functional results, such as faecal incontinence (FI), low anterior resection syndrome (LARS) or high stool frequency, can occur after colorectal resections, including proctocolectomy with ileal pouch-anal anastomosis (IPAA), rectal resection and left hemicolectomy. Management of such patients is problematic, and some case reports have demonstrated the effectiveness of sacral nerve stimulation (SNS) in these situations. Our aim was to analyse the effectiveness of SNS on poor functional results and on quality of life in patients after treatment with different types of colorectal resection. METHOD At five university hospitals from 2006 to 2014, patients with poor functional results after rectal resection, IPAA or left hemicolectomy underwent a staged SNS implant procedure. Failure was defined by the absence or insufficient improvement (< 50%) of FI episodes. RESULTS SNS for bowel dysfunction was performed in 16 patients after rectal resection with coloanal anastomosis, left hemicolectomy with colorectal anastomosis or IPAA. Two (13%) cases of primary failure were observed after the percutaneous stimulation test. Median frequency of stool, FI episodes and urgency were significantly improved in 14 patients. Wexner and LARS scores were also significantly improved for 14 patients. When we compared results according to the type of colorectal surgery (IPAA, rectal resection or left hemicolectomy), median frequencies of stool and urgency, Wexner and LARS scores were still significantly improved. Overall success rate was 75% (12/16 patients) in intention-to-treat analysis and 86% (12/14 patients with permanent electrode) in per-protocol analysis. CONCLUSION SNS seems to improve bowel dysfunction following rectal resection, left hemicolectomy or IPAA.

Abstract
BACKGROUND Sacral nerve stimulation (SNS) is a surgical treatment of fecal and urinary incontinence that consists of inserting a stimulating electrode into one of the s3 or s4 sacral holes. In addition to the benefit of SNS in the treatment of incontinence, recent studies showed that SNS is effective in the treatment of irritable bowel syndrome as well as bladder pain syndrome. The aim of this study was to evaluate the effect of SNS on visceral mechanosensitivity in a cross-organ sensitization rat model. METHODS Hypersensitive model was obtained by instillation of acetic acid into the bladder of rats during 5 minutes, 30 minutes before the start of the experiments. Visceral sensitivity was assessed by monitoring the change in mean arterial pressure in response to graded isobaric colorectal distension series. To decipher the mechanisms underlying SNS effect, rats were administered intravenously either a nonselective opioid receptor antagonist (naloxone) or a nitric oxide synthesis antagonist (L-NAME). Neuronal activation in the dorsal horn of the sacral spinal cord was measured by counting c-fos immunoreactive cells in response to colorectal distension and NMS. KEY RESULTS Intravesical acetic acid instillation increased mean arterial pressure variation in response to colorectal distension when compared to saline group. SNS reduced the variation in arterial pressure. Colorectal distension induced a rise in c-fos immunoreactive cells in the dorsal horn of the spinal cord. This effect was reduced by SNS. CONCLUSIONS & INFERENCES SNS reduces visceral mechanosensitivity in a cross-organ sensitization model.

Abstract
BACKGROUND Fecal incontinence (FI) represents a large source of morbidity and is a challenging clinical problem to manage. InterStim was approved to treat FI in 2011. Little is known about its adoption. We sought to characterize patterns of use of Interstim since Food and Drug Administration approval for FI. METHODS The New York State SPARCS database was used to evaluate InterStim use for FI from 2011 to 2014. The primary endpoint was the number of successful implantations of InterStim. Secondary endpoints included device removal, median time to removal of device, 90-day infection rates, and percentage of procedures performed by surgeon specialty and geographic location. RESULTS A total of 369 patients with FI underwent "Stage 1" of InterStim from 2011 to 2014. A total of 302 patients underwent "Stage 2," yielding a trial period failure rate of 18.2%. The majority of patients who underwent successful implantation were female (87.7%) and White (78.8%). Twenty-nine patients underwent device removal after a median duration of 147 days. Estimated risk of removal at median follow-up of 2 years was 11.8%. Colorectal surgeons comprised 51.1% of all providers followed by gynecologic (24.4%) and urologic surgeons (17.8%). A total of 71.7% of providers performed <5 procedures, while 3 of the highest volume providers performed 50.7% of all procedures. CONCLUSIONS InterStim for FI has been used by a wide variety of providers in New York State although only a few high-volume providers have performed the majority of procedures. White, female patients with Medicare are the most common recipients of InterStim. Further work must be done to develop strategies for improving access to this technology and to determine whether volume relates to outcomes.

Tech Coloproctol 2017; 21:125-132.

Abstract
BACKGROUND The Rome III criteria classify patients complaining of constipation into two main groups: patients with functional constipation (FC) and patients with constipation predominant irritable bowel syndrome (IBS-C). The purpose of this study was to identify differences in the intensity of symptoms and total and segmental colonic transit time in these two types of patients. METHODS We performed a prospective evaluation of 337 outpatients consecutively referred for chronic constipation and classified according to the Rome III criteria as FC or IBS-C. They were asked to report symptom intensity, on a 10-point Likert scale, for diarrhea, constipation, bloating and abdominal pain. Stool form was reported using the Bristol scale, and colonic transit time was measured by using multiple-ingestion single-marker single-film technique. Statistical analysis was completed by a discriminant analysis. RESULTS Female gender and obstructed defecation was more frequent in IBS-C patients than in FC patients. IBS-C patients reported greater symptom intensity than FC patients, but stool form, and total and segmental colonic transit time were not different between the two groups. Multivariate logistic regression showed that only two parameters, bloating and abdominal pain, were related to the IBS-C or to the FC phenotype, and discriminant analysis showed that these two parameters were sufficient to give a correct classification of 71% of the patients. CONCLUSIONS Our study suggests that self-evaluation of abdominal pain and bloating is more helpful than colonic transit time in classifying patient as IBS-C or FC.

Abstract
INTRODUCTION Sacral neuromodulation (SNM) remains one of the few effective treatments for refractory bladder and bowel dysfunction. However, SNM is associated with frequent need for surgical intervention, in many cases because of a failed battery. A rechargeable SNM system, with a manufacturer-reported battery life of 15 years or more, has entered post-market clinical testing in Europe but has not yet been approved for clinical testing in the United States. Areas covered: We review existing neuromodulation technologies for the treatment of lower urinary tract and bowel dysfunction and explore the limitations of available technology. In addition, we discuss implantation technique and device specifications and programming of the rechargeable SNM system in detail. Lastly, we present existing evidence for the use of SNM in bladder and bowel dysfunction and evaluate the anticipated trajectory of neuromodulation technologies over the next five years. Expert commentary: A rechargeable system for SNM is a welcome technological advance. However surgical revision not related to battery changes is not uncommon. Therefore, while a rechargeable system would be expected to reduce costs, it will not eliminate the ongoing maintenance associated with neuromodulation. No matter the apparent benefits, all new technologies require extensive post-market monitoring to ensure safety and efficacy.

Abstract
BACKGROUND Faecal incontinence (FI) is a common condition which is often under-reported. It is distressing for those suffering from it, impacting heavily on their quality of life. When conservative strategies fail, treatment options are limited. Percutaneous tibial nerve stimulation (PTNS) is a minimally invasive outpatient treatment, shown in preliminary case series to have significant effectiveness; however, no randomised controlled trial has been conducted. OBJECTIVES To assess the effectiveness of PTNS compared with sham electrical stimulation in the treatment of patients with FI in whom initial conservative strategies have failed. DESIGN Multicentre, parallel-arm, double-blind randomised (1 : 1) controlled trial. SETTING Eighteen UK centres providing specialist nurse-led (or equivalent) treatment for pelvic floor disorders. PARTICIPANTS Participants aged > 18 years with FI who have failed conservative treatments and whose symptoms are sufficiently severe to merit further intervention. INTERVENTIONS PTNS was delivered via the Urgent(®) PC device (Uroplasty Limited, Manchester, UK), a hand-held pulse generator unit, with single-use leads and fine-needle electrodes. The needle was inserted near the tibial nerve on the right leg adhering to the manufacturer's protocol (and specialist training). Treatment was for 30 minutes weekly for a duration of 12 treatments. Validated sham stimulation involved insertion of the Urgent PC needle subcutaneously at the same site with electrical stimulation delivered to the distal foot using transcutaneous electrical nerve stimulation. MAIN OUTCOME MEASURES Outcome measures were assessed at baseline and 2 weeks following treatment. Clinical outcomes were derived from bowel diaries and validated, investigator-administered questionnaires. The primary outcome classified patients as responders or non-responders, with a responder defined as someone having achieved ≥ 50% reduction in weekly faecal incontinence episodes (FIEs). RESULTS In total, 227 patients were randomised from 373 screened: 115 received PTNS and 112 received sham stimulation. There were 12 trial withdrawals: seven from the PTNS arm and five from the sham arm. Missing data were multiply imputed. For the primary outcome, the proportion of patients achieving a ≥ 50% reduction in weekly FIEs was similar in both arms: 39 in the PTNS arm (38%) compared with 32 in the sham arm (31%) [odds ratio 1.28, 95% confidence interval (CI) 0.72 to 2.28; p = 0.396]. For the secondary outcomes, significantly greater decreases in weekly FIEs were observed in the PTNS arm than in the sham arm (beta -2.3, 95% CI -4.2 to -0.3; p = 0.02), comprising a reduction in urge FIEs (p = 0.02) rather than passive FIEs (p = 0.23). No significant differences were found in the St Mark's Continence Score or any quality-of-life measures. No serious adverse events related to treatment were reported. CONCLUSIONS PTNS did not show significant clinical benefit over sham electrical stimulation in the treatment of FI based on number of patients who received at least a 50% reduction in weekly FIE. It would be difficult to recommend this therapy for the patient population studied. Further research will concentrate on particular subgroups of patients, for example those with pure urge FI.

Abstract
PURPOSE Faecal incontinence (FI) is distressing, significantly reduces quality of life (QoL) and has few pharmacological treatments. The α1-adrenoceptor agonist NRL001 (1R,2S-methoxamine hydrochloride) improves anal sphincter tone. NRL001 efficacy was evaluated by changes in Wexner scores at week 4 vs. baseline in NRL001-treated patients compared with placebo. Impact of NRL001 on QoL and safety were also assessed. METHODS Four hundred sixty-six patients received NRL001 (5, 7.5 or 10 mg) or placebo as suppository, once daily over 8 weeks. Wexner score, Vaizey score and QoL were analysed at baseline, week 4 and week 8. FI episodes and adverse events were recorded in diaries. RESULTS At week 4, mean reductions in Wexner scores were -3.0, -2.6, -2.6 and -2.4 for NRL001 5, 7.5, 10 mg and placebo, respectively. All reduced further by week 8. As placebo responses also improved, there was no significant treatment effect at week 4 (p = 0.6867) or week 8 (p = 0.5005). FI episode frequency improved for all patients, but not significantly compared with placebo (week 4: p = 0.2619, week 8: p = 0.5278). All patients' QoL improved, but not significantly for all parameters (p > 0.05) except depression/self-perception at week 4 (p = 0.0102) and week 8 (p = 0.0069), compared with placebo. Most adverse events were mild and judged probably or possibly related to NRL001. CONCLUSIONS All groups demonstrated improvement in efficacy and QoL compared with baseline. NRL001 was well-tolerated without serious safety concerns. Despite the improvement in all groups, there was no statistically significant treatment effect, underlining the importance of relating results to a placebo arm.

Abstract
BACKGROUND Most studies on sacral nerve stimulation (SNS) are either single-centre with small numbers of patients or multi-centre studies. We present the medium-term follow-up results from a single centre for 127 patients undergoing SNS. METHODS Consecutive patients treated with SNS for faecal incontinence had preoperative baseline St Mark's continence scores, faecal incontinence quality of life (FIQL) measures and anorectal physiology studies. Follow-up was a postal questionnaire concerning continence, FIQL, patient-perceived change in bowel control (-5 to +5 where 0 is no change), overall satisfaction (0-10 visual analogue scale) and use of medications. RESULTS A total of 166 patients underwent temporary nerve stimulation testing, of which 112 progressed to a permanent implantable pulse generator (IPG). Fifteen received an IPG without the testing phase, hence 127 patients in total. Fourteen had the IPG removed, four were deceased, leaving 109 for assessment; 91 (83%) responded to the survey. Mean follow-up was 2.7 years (range: 2 months-8.5 years). Mean baseline St Mark's continence score was 14.4, and mean follow-up score was 10.3 (P < 0.01). FIQL improved in all domains (P < 0.001). Patient-reported improved bowel control mean score was +3.2 (95% CI: 2.9, 3.55). Median satisfaction score was 8.0 (range: 0-10). Complications included 17 lead dislodgements, seven superficial infections, five infections requiring surgery and five repositioning of a rotated IPG. Thirty-two patients used loperamide and 34 used fibre supplements. CONCLUSION In this observational study, limited by the absence of a placebo control group, SNS significantly improved continence and quality of life, and patient satisfaction was high.

Abstract
BACKGROUND No systematic review has examined the collective randomized and nonrandomized evidence for fecal incontinence treatment effectiveness across the range of surgical treatments. OBJECTIVE The purpose of this study was to assess the efficacy, comparative effectiveness, and harms of surgical treatments for fecal incontinence in adults. DATA SOURCES Ovid MEDLINE, EMBASE, Physiotherapy Evidence Database, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine, and the Cochrane Central Register of Controlled Trials, as well as hand searches of systematic reviews, were used as data sources. STUDY SELECTION Two investigators screened abstracts for eligibility (surgical treatment of fecal incontinence in adults, published 1980-2015, randomized controlled trial or observational study with comparator; case series were included for adverse effects). Full-text articles were reviewed for patient-reported outcomes. We extracted data, assessed study risk of bias, and evaluated strength of evidence for each treatment-outcome combination. INTERVENTIONS Surgical treatments for fecal incontinence were included interventions. MAIN OUTCOME MEASURES Fecal incontinence episodes/severity, quality of life, urgency, and pain were measured. RESULTS Twenty-two studies met inclusion criteria (13 randomized trials and 9 observational trials); 53 case series were included for harms. Most patients were middle-aged women with mixed FI etiologies. Intervention and outcome heterogeneity precluded meta-analysis. Evidence was insufficient for all of the surgical comparisons. Few studies examined the same comparisons; no studies were high quality. Functional improvements varied; some authors excluded those patients with complications or lost to follow-up from analyses. Complications ranged from minor to major (infection, bowel obstruction, perforation, and fistula) and were most frequent after the artificial bowel sphincter (22%-100%). Major surgical complications often required reoperation; few required permanent colostomy. LIMITATIONS Most evidence is intermediate term, with small patient samples and substantial methodologic limitations. CONCLUSIONS Evidence was insufficient to support clinical or policy decisions for any surgical treatments for fecal incontinence in adults. More invasive surgical procedures had substantial complications. The lack of compliance with study reporting standards is a modifiable impediment in the field. Future studies should focus on longer-term outcomes and attempt to identify subgroups of adults who might benefit from specific procedures.

Abstract
This report defines criteria and reviews the epidemiology, pathophysiology, and management of common anorectal disorders: fecal incontinence (FI), functional anorectal pain and functional defecation disorders. FI is defined as the recurrent uncontrolled passage of fecal material for at least 3 months. The clinical features of FI are useful for guiding diagnostic testing and therapy. Anorectal manometry and imaging are useful for evaluating anal and pelvic floor structure and function. Education, antidiarrheals and biofeedback therapy are the mainstay of management; surgery may be useful in refractory cases. Functional anorectal pain syndromes are defined by clinical features and categorized into three subtypes. In proctalgia fugax, the pain is typically fleeting and lasts for seconds to minutes. In levator ani syndrome (LAS) and unspecified anorectal pain the pain lasts more than 30 minutes, but in LAS there is puborectalis tenderness. Functional defecation disorders are defined by >2 symptoms of chronic constipation or irritable bowel syndrome with constipation, and with >2 features of impaired evacuation i.e., abnormal evacuation pattern on manometry, abnormal balloon expulsion test or impaired rectal evacuation by imaging. It includes two subtypes; dyssynergic defecation and inadequate defecatory propulsion. Pelvic floor biofeedback therapy is effective for treating LAS and defecatory disorders.

Do endoflip assessments of anal sphincter distensibility provide more information on patients with fecal incontinence than high-resolution anal manometry? Neurogastroenterol Motil 2016; 28:399-409. [PMID: 26670599 DOI: 10.1111/nmo.12740] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2015] [Accepted: 10/30/2015] [Indexed: 12/15/2022]
Abstract
BACKGROUND Anal manometry is the standard technique for evaluating anal sphincter function. However, the functional lumen imaging probe (EndoFLIP(®) ) can be used to measure sphincter distensibility during volume-controlled distensions. Our aims were (i) to assess anal distensibility in patients with fecal incontinence (FI) and in healthy subjects using the EndoFLIP(®) and (ii) to compare the results with anal pressures measured by 3D high-resolution manometry (3D-HRM) to determine whether the EndoFLIP(®) was more sensitive and specific for diagnosing FI than 3D-HRM. METHODS EndoFLIP(®) and 3D-HRM assessments of 34 female FI patients and 40 healthy female subjects were performed. Anal distensibility was measured as the median cross-sectional area at the narrowest point divided by the corresponding intra-bag pressure at rest and during peak voluntary contraction and was expressed in mm(2) /mmHg. KEY RESULTS A 40-mL anal distensibility index was selected for further comparisons as it provided the best discrimination between the FI patients and the healthy subjects. The index was significantly higher in the FI patients than in the healthy subjects at rest (p = 1.10(-4) ) and during voluntary contraction (p = 1.10(-4) ). The index at rest and during voluntary contraction appeared to be more appropriate than anal pressures for discriminating between FI patients and healthy subjects. CONCLUSIONS & INFERENCES The present study confirmed that FI is associated with an abnormally high distensibility index at rest and during voluntary contraction. The ability of the distensibility index to discriminate between FI patients and healthy subjects was significantly better than anal pressure.

Gastric Electrical Stimulation and Sacral Electrical Stimulation: A Long-Term Follow-Up Study of Dual-Device Treatment. Dig Dis Sci 2016; 61:176-80. [PMID: 26280085 PMCID: PMC5098804 DOI: 10.1007/s10620-015-3840-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2015] [Accepted: 07/30/2015] [Indexed: 01/26/2023]
Abstract
AIMS The objective of this study was to investigate sacral electrical stimulation (SES) and gastric electrical stimulation (GES) by comparing upper and lower gastrointestinal (GI) and genitourinary (GU) symptoms and quality of life, before treatment and in the long term after treatment. We hypothesized that dual-device treatment would greatly improve upper and lower gastrointestinal and genitourinary symptoms, as well as quality of life. METHODS Fifty-four patients who underwent dual-device treatment (GES and SES) were enrolled in this study. Patients who had surpassed 24 months since the second-device insertion were included. Patients were evaluated before and after both devices were implanted and given a symptom questionnaire regarding their upper GI, lower GI, and GU symptoms and their quality of life. RESULTS With combined treatment, a statistically significant improvement was seen in upper GI, lower GI, and GU symptoms and quality of life. However, fecal incontinence and fecal urgency improvements did not reach statistical significance, likely due to the small sample size. CONCLUSION The implantation of two stimulators appears to be safe and effective to improve patients' quality of life for those with upper GI symptoms, bowel problems, and bladder dysfunction.

Bilateral compared with unilateral sacral nerve stimulation for faecal incontinence: results of a randomized, single-blinded crossover study. Colorectal Dis 2015; 17:1085-93.

Abstract
AIM This randomized single-blinded crossover study aimed to investigate whether bilateral sacral nerve stimulation (SNS) is more efficient than unilateral stimulation for faecal incontinence (FI). METHOD Patients with FI who responded during a unilateral test stimulation, with a minimum improvement of 50% were eligible. Twenty-seven patients who were accepted to enter the trial were bilaterally implanted with two permanent leads and pacemakers. Patients were randomized into three periods of 4 weeks' stimulation including unilateral right, unilateral left and bilateral stimulation. Symptoms scores and bowel habit diaries were collected at baseline and in each study period. A 1-week washout was introduced between each study period. RESULTS Twenty-seven (25 female) patients with a median age of 63 (36-84) years were bilaterally implanted from May 2009 to June 2012. The median number of episodes of FI per 3 weeks significantly decreased from 17 (3-54) at baseline to 2 (0-20) during stimulation on the right side, 2 (0-42) during stimulation on the left side and 1 (0-25) during bilateral stimulation. The Wexner incontinence score improved significantly from a median of 16 (10-20) at baseline to 9 (0-14) with right-side stimulation, 10 (0-15) with left-side stimulation and 9 (0-14) with bilateral stimulation. The differences between unilateral right or unilateral left and bilateral stimulation were non-significant, for FI episodes (P = 0.3) or for Wexner incontinence score (P = 0.9). CONCLUSION Bilateral SNS therapy for FI is not superior to standard unilateral stimulation in the short term. Equal functional results can be obtained regardless of the side of implantation.

Abstract
INTRODUCTION Fecal incontinence is a debilitating condition affecting primarily the elderly. Many patients suffer in silence resulting in both underdiagnosis and undertreatment often culminating in an overall poor quality of life. METHODS We sought to review the etiology, diagnosis, and treatment of fecal incontinence based on current literature. Additionally, newer treatment methods such as Solesta will be evaluated. RESULTS There are many diagnostic modalities available to assess the degree and severity of the patient's incontinence; however, a thorough history and physical exam is critical. Initial attempts at treatment focus on medical management primarily through stool texture modification with the aid of bulking agents. Failure of medical therapy is often followed by a graded increase in the complexity and invasiveness of the available treatment options. The selection of the most appropriate surgical option, such as overlapping sphincteroplasty and neuromodulation, is multifactorial involving both surgeon and patient-related factors. Neuromodulation has received increased attention in the last decade due to its documented therapeutic success, and newer office-based procedures, such as the Solesta injection, are showing promising results in properly selected patients. Finally, diversion remains an option for select patients who have failed all other therapies. CONCLUSION The etiology of fecal incontinence is multifactorial, involving a complex interplay between stool consistency and anatomic integrity. The diagnosis and treatment of fecal incontinence continue to evolve and are showing promising results.
