The Long-term Outcomes of Sacral Neuromodulation for Fecal Incontinence: A Single-Center Experience.

BACKGROUND: Sacral neuromodulation is an effective treatment for fecal incontinence. OBJECTIVE: To assess the long-term outcomes of sacral neuromodulation and establish the outcomes of patients with inactive devices. DESIGN: This is an observational study of patients treated for >5 years. A positive outcome was defined as a more than 50% reduction in fecal incontinence episodes or improvement in a symptom severity score. Data were reviewed from a prospectively managed database. SETTINGS: This study was conducted at a single tertiary referral center. PATIENTS: Data from 74 patients (72 women) were available at long-term follow-up. MAIN OUTCOME MEASURES: Bowel diary, St. Mark's incontinence score, and Manchester Health Questionnaire data were prospectively recorded at baseline, after percutaneous nerve evaluation, and at last follow-up. RESULTS: Patients were analyzed in cohorts based on time since sacral neuromodulation implantation: group 1: 5 to 10 years (n = 20), group 2: >10 years (n = 35), and group 3: inactive sacral neuromodulation devices (n = 19). Median St. Mark's incontinence score and Manchester Health Questionnaire improved from baseline to last follow-up in group 1 ( p ≤ 0.05) and group 2 ( p ≤ 0.05), but in group 3, results returned to baseline levels at the last follow-up. Similarly, weekly fecal incontinence episodes improved in both active device groups at the last follow-up. However, in group 3, incontinence episodes were no different from baseline ( p = 0.722). Despite active devices, fecal urgency episodes increased at the last follow-up after >10 years since percutaneous nerve evaluation ( p ≤ 0.05). Complete continence was reported by 44% of patients, and at least a 50% improvement was seen in 77% of patients with active devices. LIMITATIONS: This study is retrospective with some gaps in the available data at the last follow-up. CONCLUSIONS: Sacral neuromodulation is an effective treatment for fecal incontinence in the long term, but all outcomes are adversely affected by device inactivity. Therefore, ongoing stimulation is required for continued benefit. See Video Abstract.

De manera similar, los episodios semanales de incontinencia fecal mejoraron en ambos grupos de dispositivos activos en el último seguimiento. Sin embargo, en el Grupo 3 los episodios de incontinencia no fueron diferentes de los basales (p = 0,722). A pesar de los dispositivos activos, los episodios de urgencia fecal aumentaron en el último seguimiento después de más de 10 años desde la evaluación del nervio periférico (p = < 0,05).

Por lo tanto, se requiere estimulación continua para un beneficio continuo. (Traducción- Dr. Francisco M. Abarca-Rendon ).

Patient Satisfaction With Long-term Sacral Neuromodulation for Fecal Incontinence: Experience From a Single Tertiary Center.

BACKGROUND: Sacral neuromodulation is an effective treatment for fecal incontinence in the long term. Efficacy is typically assessed using bowel diary, symptom severity, and quality-of-life questionnaires, and "success" is defined as more than 50% improvement in these measures. However, patient satisfaction may be a more meaningful and individualized measure of treatment efficacy. OBJECTIVE: To assess patient-reported satisfaction with long-term sacral neuromodulation and compare it to the frequently applied efficacy measures. DESIGN: An observational study of a prospectively maintained database. SETTING: A single tertiary pelvic floor referral unit. PATIENTS: Data from 70 patients (68 women, median age 69 [60-74] years) were available. The median time since implantation was 11 (9-14) years. Nineteen patients reported inactive neuromodulation devices. MAIN OUTCOME MEASURES: Bowel diaries, the Manchester Health Questionnaire, and the St. Mark's Incontinence Score were recorded at baseline, after percutaneous nerve evaluation, and at the last follow-up. Patient-reported satisfaction, using a 0% to 100% visual analog scale, with treatment since implantation (overall) and in the 2 weeks preceding completion of the last outcome measures (current) were also assessed. RESULTS: Satisfaction was significantly higher in those with active sacral neuromodulation devices (75% vs 20%, p < 0.001) at follow-up. No significant relationships exist between symptom improvement using conventional measures and patient-reported satisfaction. Current satisfaction was not associated with changes in bowel diary data after percutaneous nerve evaluation. Despite improvements in the St. Mark's Incontinence Score and Manchester Health Questionnaire below the 50% improvement threshold used to define "success," patients reported high (80%) satisfaction. LIMITATIONS: Retrospective design with gaps in the available data. CONCLUSIONS: High patient satisfaction with sacral neuromodulation can be achieved; however, the response to percutaneous nerve evaluation may not predict treatment satisfaction in the long term. The change in questionnaire results, which measure the use of compensatory behaviors and quality-of-life impact, may better correspond to treatment satisfaction. SATISFACCIN A LARGO PLAZO EN LOS PACIENTES CON LA NEUROMODULACIN SACRA PARA LA INCONTINENCIA FECAL EXPERIENCIA DE UN NICO CENTRO TERCIARIO: ANTECEDENTES:La neuromodulación sacra es un tratamiento eficaz para la incontinencia fecal a largo plazo. La eficacia suele evaluarse mediante cuestionarios sobre la frecuencia diaria intestinal, la gravedad de los síntomas o la calidad de vida, y el "éxito" se define como una mejoría >50% en estas medidas. Sin embargo, la satisfacción del paciente puede ser una medida más significativa e individualizada de la eficacia del tratamiento.OBJETIVO:Evaluar la satisfacción a largo plazo de los pacientes con la neuromodulación sacra y compararla con las medidas de eficacia aplicadas con frecuencia.DISEÑO:Estudio observacional de una base de datos mantenida prospectivamente.LUGAR:Unidad terciaria única de referencia de suelo pélvico.PACIENTES:Se dispuso de datos de 70 pacientes (68 mujeres, mediana de edad 69 [60-74]). La mediana de tiempo transcurrido desde la implantación fue de 11 (9-14) años. Diecinueve pacientes informaron de dispositivos de neuromodulación inactivos.PRINCIPALES MEDIDAS DE VALORACIÓN:Diarios intestinales, el Cuestionario de Salud de Manchester y la Puntuación de Incontinencia de St Marks registrados al inicio, tras la evaluación percutánea del nervio y en el último seguimiento. Los pacientes informaron de su satisfacción, utilizando una escala analógica visual de 0%-100%, con el tratamiento desde la implantación (global) y en las dos semanas anteriores a la realización de las últimas medidas de resultado (actual).RESULTADOS:La satisfacción fue significativamente mayor en los pacientes con dispositivos de neuromodulación sacra activos (75% frente a 20%, p < 0,001) durante el seguimiento. No existen relaciones significativas entre la mejoría de los síntomas mediante medidas convencionales y la satisfacción comunicada por el paciente. La satisfacción actual no se asoció con los cambios en los datos de la frecuencia diaria intestinal tras la evaluación percutánea de los nervios. A pesar de que las mejoras en la puntuación de incontinencia de St Mark y el Cuestionario de Salud de Manchester se situaron por debajo del umbral de mejora del 50% utilizado para definir el "éxito", los pacientes declararon un alto grado de satisfacción (80%).LIMITACIONES:Retrospectivo con lagunas en los datos disponibles.CONCLUSIONES:Puede lograrse una alta satisfacción de los pacientes con la neuromodulación sacra; sin embargo, la respuesta a la evaluación percutánea del nervio puede no predecir la satisfacción con el tratamiento a largo plazo. El cambio en los resultados del cuestionario, que mide el uso de conductas compensatorias y el impacto en la calidad de vida, puede corresponder mejor a la satisfacción con el tratamiento.

Interventions to Improve Patient Care on Surgical Ward Rounds: A Systematic Review.

BACKGROUND: Ward rounds are an essential component of surgical and perioperative care. However, the relative effectiveness of different interventions to improve the quality of surgical ward rounds remains uncertain. The aim of this systematic review was to evaluate the efficacy of various ward round interventions among surgical patients. METHODS: A systematic literature search of the MEDLINE (OVID), EMBASE (OVID), Scopus, Cumulative Index of Nursing and Allied Health (CINAHL), and PsycInfo databases was performed on 7 October 2022 in accordance with PRISMA guidelines. All studies investigating surgical ward round quality improvement strategies with measurable outcomes were included. Data were analysed via narrative synthesis based on commonly reported themes. RESULTS: A total of 28 studies were included. Most were cohort studies (n = 25), followed by randomised controlled trials (n = 3). Checklists/proformas were utilised most commonly (n = 22), followed by technological (n = 3), personnel (n = 2), and well-being (n = 1) quality improvement strategies. The majority of checklist interventions (n = 21, 95%) showed significant improvements in documentation compliance, staff understanding, or patient satisfaction. Other less frequently reported ward round interventions demonstrated improvements in communication, patient safety, and reductions in patient stress levels. CONCLUSIONS: Use of checklists, technology, personnel, and well-being improvement strategies have been associated with improvements in ward round documentation, communication, as well as staff and patient satisfaction. Future studies should investigate the ease of implementation and long-term durability of these interventions, in addition to their impact on clinically relevant outcomes such as patient morbidity and mortality.

Chromoscopy versus conventional endoscopy for the detection of polyps in the colon and rectum.

BACKGROUND: Although conventional colonoscopy is the most accurate test available for the investigation of the colorectum for polyps, data exist that raise concerns about its sensitivity. Chromoscopy (spraying dye onto the surface of the colon to make polyps more visible) may be one way of enhancing the ability of colonoscopy to detect polyps, particularly diminutive flat lesions, which otherwise may be difficult to detect. OBJECTIVES: To determine whether the use of chromoscopy enhances the detection of polyps and neoplasia during endoscopic examination of the colon and rectum. SEARCH METHODS: We searched the following databases: Cochrane Colorectal Cancer Group Specialised Register (October 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library; Issue 10, 2015), MEDLINE (January 1950 to October 2015), EMBASE (January 1974 to October 2015), and ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform (both November 2015). We also handsearched abstracts from relevant meetings from 1980 to 2015. Search terms included 'randomised trials' containing combinations of the following: 'chromoscopy' 'colonoscopy' 'dye-spray' 'chromo-endoscopy' 'indigo-carmine' 'magnifying endoscopy'. SELECTION CRITERIA: We included all prospective randomised trials comparing chromoscopic with conventional endoscopic examination of the whole of the colon and rectum. We excluded studies of people with inflammatory bowel disease or polyposis syndromes and any studies that combined chromoscopy with additional interventions (cap assistance, water-perfused, etc.). DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the methodological quality of potentially eligible trials, and two review authors independently extracted data from the included trials. Outcome measures included the detection of polyps (neoplastic and non-neoplastic), the detection of diminutive lesions, the number of participants with multiple neoplastic lesions, and the extubation time. MAIN RESULTS: We included seven trials (2727 participants) in this update. Five trials were of sufficiently similar design to allow for pooled results. Two trials differed substantially in design and were included in a subgroup analysis. All the trials had some methodological drawbacks. However, combining the results showed a significant difference in favour of chromoscopy for all detection outcomes. In particular, chromoscopy was likely to yield significantly more people with at least one neoplastic lesion (odds ratio (OR) 1.53, 95% confidence interval (CI) 1.31 to 1.79; 7 trials; 2727 participants), and at least one diminutive neoplastic lesion (OR 1.51, 95% CI 1.19 to 1.92; 4 trials; 1757 participants). Significantly more people with three or more neoplastic lesions were also detected, but only when studies that used high-definition colonoscopy in the control group were excluded (OR 4.63, 95% CI 1.99 to 10.80; 2 trials; 519 participants). None of the included studies reported any adverse events related to the use of the contrast dye. AUTHORS' CONCLUSIONS: There is strong evidence that chromoscopy enhances the detection of neoplasia in the colon and rectum. People with neoplastic polyps, particularly those with multiple polyps, are at increased risk of developing colorectal cancer. Such lesions, which presumably would be missed with conventional colonoscopy, could contribute to the interval cancer numbers on any surveillance programme.

Variation in the definition of 'failure to rescue' from postoperative complications: a systematic review and recommendations for outcome reporting.

BACKGROUND: Failure to rescue is the rate of death amongst patients with postoperative complications and has been proposed as a perioperative quality indicator. However, variation in its definition has limited comparisons between studies. We systematically reviewed all surgical literature reporting failure to rescue rates and examined variations in the definition of the 'numerator,' 'denominator,' and timing of failure to rescue measurement. METHODS: Databases were searched from inception to 31 December 2022. All studies reporting postoperative failure to rescue rates as a primary or secondary outcome were included. We examined the complications included in the failure to rescue denominator, the percentage of deaths captured by the failure to rescue numerator, and the timing of measurement for complications and mortality. RESULTS: A total of 359 studies, including 212,048,069 patients, were analyzed. The complications included in the failure to rescue denominator were reported in 295 studies (82%), with 131 different complications used. The median number of included complications per study was 10 (interquartile range 8-15). Studies that included a higher number of complications in the failure-to-rescue denominator reported lower failure-to-rescue rates. Death was included as a complication in the failure to rescue the denominator in 65 studies (18%). The median percentage of deaths captured by the failure to rescue calculation when deaths were not included in the denominator was 79%. Complications (52%) and mortality (40%) were mostly measured in-hospital, followed by 30-days after surgery. CONCLUSION: Failure to rescue is an important concept in the study of postoperative outcomes, although its definition is highly variable and poorly reported. Researchers should be aware of the advantages and disadvantages of different approaches to defining failure to rescue.

Chromoscopy versus conventional endoscopy for the detection of polyps in the colon and rectum.

BACKGROUND: Although conventional colonoscopy is the most sensitive test available for the investigation of the colorectum for polyps, there are data that raise concerns about its sensitivity. Chromoscopy may be one way of enhancing the ability for colonoscopy to detect polyps particularly diminutive flat lesions that may be otherwise difficult to detect. OBJECTIVES: To determine whether the use of chromoscopy enhances detection of polyps and neoplasia during endoscopic examination of the colon and rectum. SEARCH STRATEGY: MEDLINE, EMBASE and the Cochrane Library databases were searched (April 2010) along with a hand search of abstracts from relevant meetings. Search terms included randomised trials containing combinations of the following: 'chromoscopy' 'colonoscopy' 'dye-spray' 'chromo-endoscopy' 'indigo-carmine' 'magnifying endoscopy'. SELECTION CRITERIA: All prospective randomised trials comparing chromoscopic with conventional endoscopic examination of the lower gastrointestinal tract were included. Patients with inflammatory bowel disease or polyposis syndromes were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers assessed the methodological quality of potentially eligible trials and independently extracted data from the included trials. Outcome measures included the detection of polyps (neoplastic and non-neoplastic), the detection of diminutive lesions, the number of patients with multiple neoplastic lesions and the extubation time. MAIN RESULTS: Five trials were included in this update, and although there were some methodological drawbacks and differences in study design, combining the results showed a significant difference in favour of chromoscopy for all detection outcomes. In particular, chromoscopy is likely to yield significantly more patients with at least one neoplastic lesion (OR 1.67 (CI 1.29-2.15)) and significantly more patients with three or more neoplastic lesions (OR 2.55 (CI 1.49-4.36)). Not surprisingly the withdrawal times were significantly slower for the chromoscopy group. AUTHORS' CONCLUSIONS: There appears to be strong evidence that chromoscopy enhances the detection of neoplasia in the colon and rectum. Patients with neoplastic polyps, particularly those with multiple polyps, are at increased risk of developing colorectal cancer. Such lesions, which presumably would be missed with conventional colonoscopy, could contribute to the interval cancer numbers on any surveillance programme.

The distance between the sural nerve and ideal portal placements in lateral subtalar arthroscopy: a cadaveric study.

BACKGROUND: There have been limited studies assessing the relative safety of lateral portals for subtalar arthroscopy in terms of their distance from the sural nerve and its branches. The aim of this cadaveric study was to assess and compare the distance of lateral subtalar arthroscopy portal sites to the sural nerve and its branches. MATERIALS AND METHODS: Twenty embalmed cadaveric lower limbs were dissected exposing the nerves and tendons and subtalar arthroscopy portals were replicated using pins. The anatomically important distances were measured with a digital caliper. Statistical analysis of the data was performed using SPSS for Windows 11.5 (SPSS Inc, Chicago, IL) using Friedman Tests and Wilcoxon Signed Ranks tests. RESULTS: The median distance of the anterior and middle subtalar portals to the nearest nerve was 21.3 mm and 20.9 mm, respectively, and 11.4 mm for the posterior portal. There was no statistically significant difference between anterior and middle portals (p=0.87) but there was statistically significant difference between anterior versus posterior and middle versus posterior portals (p=0.001 in each comparison). CONCLUSION: The anterior and middle subtalar portals were both less likely to damage important structures than the posterior subtalar portal. CLINICAL RELEVANCE: The results of this study can be of value to the surgeon when planning arthroscopic procedures to the subtalar joint from the lateral approach.

Posterior ankle arthroscopy portal safety regarding proximity to the tibial and sural nerves.

The aim of this cadaveric study was to assess the relative safety of posterior ankle arthroscopy portal sites regarding their distance from the tibial and sural nerves. We dissected 20 embalmed cadaveric lower limbs, carefully exposed the nerves, preserving their original position, and established the entry points of five posterior ankle portals using pins. We measured distances with a digital calliper and used Friedman test and Wilcoxon Signed Ranks tests for statistical analyses. There was unequal safety between the five portals (p = 0.00001). There was no statistically significant difference between the two posterolateral or two posteromedial portals. The trans-Achilles tendon portal as expected was significantly further away from either nerve (p = 0.00001). In conclusion, the trans-Achilles portal is the safest portal in terms of its distance from the nerves but has the disadvantage of surgical injury to the Achilles tendon. The two medial and two lateral posterior portals are equivalent in terms of safety.

The long-term efficacy of fissurectomy and botulinum toxin injection for chronic anal fissure in females.

INTRODUCTION: Healing rates for botulinum toxin injection for anal fissure may be improved if combined with fissurectomy. This procedure has a decreased risk of incontinence, which is particularly important in females. We investigated the long-term efficacy of fissurectomy and botulinum toxin injection for chronic resistant fissures in females. METHODS: Female patients who consented underwent excision of the fissure edges and injection of 25-100 units of botulinum into the intersphincteric space. Patients were followed up 2 months after the procedure and over a period of up to 39 months. RESULTS: Forty-six patients (mean age, 42 years) were recruited. No patient had incontinence symptoms preoperatively. At a median follow-up period of 11 months, there was a cure rate of 85 percent in 44 patients. After a median follow-up of 22 months, 12 more patients were lost to follow-up. Of the remaining patients, 16 (50 percent) suffered recurrence during the follow-up period. Five patients required further surgical intervention. Three patients suffered chronic perianal infection requiring antibiotic treatment or surgery. There was one case of incontinence at final assessment: the patient complained of urge incontinence, which has persisted for more than 18 months. CONCLUSIONS: Fissurectomy and botulinum toxin injection for the treatment of chronic anal fissure in females seems to be effective in the medium-term but there is a high rate of late recurrence. However, only a minority of patients proceed to more invasive surgical intervention, which may make it a useful option in patients not suitable for lateral sphincterotomy.

Endoscopic resection of adenoma-like mass in chronic ulcerative colitis using a combined endoscopic mucosal resection and cap assisted submucosal dissection technique.

BACKGROUND: Resection of an adenoma-like mass (ALM) in chronic ulcerative colitis (CUC) complicated by mucosal fibrosis has historically not been technically feasible. Endoscopic submucosal dissection techniques may now provide a therapeutic tool enabling the division of submucosal fibrotic scarring, hence enabling endoluminal resection for the first time in this select patient group. The aim was prospective evaluation of endoscopic submucosal dissection-assisted (ESD) resection of flat, sessile, and lateral spreading tumors in CUC complicated by submucosal desmoplasis. Clinical endpoints were postresection recurrence rates, R0 resection status, and complications. METHODS: ESD-assisted endoscopic mucosal resection (EMR) using the Olympus KD-630L insulation-tipped knife was performed on selected lesions. RESULTS: Sixty-nine patients met inclusion criteria, of which 2 were excluded due to follow-up default. En bloc resection was performed in 52/67 (78%) cases with 15/67 (7%) requiring a piecemeal approach. R0 resection was achieved in 49/52 (94%) of lesions undergoing en bloc resection (perforation rate 2/67 [3%]). Bleeding complications occurred in 7/67 (10%) of cases. No metachronous circumscribed intraepithelial neoplastic lesions or cancer was detected at follow-up. At a median of 18 months follow-up, overall cure rates for the ESD-assisted EMR cohort was 66/67 (98%). CONCLUSIONS: We have shown for the first time that endoscopic resection of ALM even in the presence of complicating mucosal fibrosis is technically achievable using a combined ESD-assisted EMR technique. In an appropriately selected cohort, this technique may provide a technically feasible and clinically acceptable therapy where otherwise colectomy would be required.
