Gassner L, Wild C, Walter M. Clinical effectiveness and safety of self-expandable implantable bulking agents for faecal incontinence: a systematic review. BMC Gastroenterol 2022; 22:389. [PMID: 35978293 PMCID: PMC9386976 DOI: 10.1186/s12876-022-02441-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Accepted: 07/20/2022] [Indexed: 11/10/2022] Open
Abstract
PURPOSE The purpose of this systematic review is to evaluate whether self-expandable implantable vs non-self-expandable injectable bulking agents (second-line therapies) are equal/superior in terms of effectiveness (severity, quality of life [QoL]) and safety (adverse events) for faecal incontinence (FI). METHODS A systematic review was conducted, and five databases were searched (Medline via Ovid, Embase, Cochrane Library, University of York Centre for Reviews and Dissemination, and International Network of Agencies for Health Technology database). In-/exclusion criteria were predefined according to the PICOS scheme. The Institute of Health Economics risk of bias (RoB) tool assessed studies' internal validity. According to the Grading of Recommendations, Assessment, Development and Evaluation approach, the strength of evidence for safety outcomes was rated. A qualitative synthesis of the evidence was used to analyse the data. RESULTS The evidence consists of eight prospective single-arm, before-after studies (166 patients) fulfilling the inclusion criteria for assessing clinical effectiveness and safety of implantable bulking agents. FI severity statistically significantly improved in five of seven studies rated by the Cleveland Clinic FI Score and in three of five studies measured by the Vaizey score. Statistically significant improved disease-related QoL was found in one of five studies measured by the FI QoL Score and in one of two studies rated by the American Medical Systems score. Procedure-related adverse events occurred in 16 of 166 patients (i.e., intraoperative complications, anal discomfort and pain). Device-related adverse events occurred in 48 of 166 patients, including prostheses' dislodgement and removed/extruded prostheses. Studies were judged with moderate/high RoB. The strength of evidence for safety was judged to be very low. CONCLUSION Implantable bulking agents might be an effective and safe minimally invasive option in FI treatment if conservative therapies fail. FI severity significantly improved, however, effects on QoL need to be explored in further studies. Due to the uncontrolled nature of the case series, comparative studies need to be awaited.

Artif Organs 2022; 46:2391-2399. [PMID: 35866428 DOI: 10.1111/aor.14369] [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: 04/05/2022] [Revised: 07/05/2022] [Accepted: 07/18/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Artificial organs are playing an increasingly important role in medical field. Artificial anal sphincter, as an example, is a widely used medical device for fecal incontinence. Though it could help patients maintain continence, the issue of perception reconstruction is still unsolved, which means that patients cannot control defecation as desired. METHODS In this paper, a novel sensor system based on vector similarity has been analyzed and evaluated. The sensor system is a self-packaged strain gauge sensor with a small size 14.5mm x 6mm, especially for medical device implanted in body to reconstruct perception function. In order to overcome the disadvantages of single threshold judgment, a more accurate and reliable judgment standard for content pressure detection in rectum is developed by using vector similarity method. Therefore, in the novel sensor system, standard multi-parameters are comprehensive considered. Furthermore, weight-optimization of sensors are investigated since each sensor has played a different role in detection. Finally, sensor calibration, in vitro and in vivo experiments are established. RESULTS In sensor calibration, the result R2 > 0.99 presents the strain gauge pressure sensor has a good linearity. After that, a series of in vitro experiments have been conducted. The optimized sensor system shows a high accuracy rate in perception reconstruction, which is 87.5% on early warning and 95% on the alarm. In the following in vivo experiments. The results indicate that the average accuracy of the proposed perception reconstruction module has increased by 17.7%, compared with that without optimized sensor system. CONCLUSIONS All of these have proven that the novel perception reconstruction module with sensor system based on vector similarity is more acceptable and reliable.

Abstract
Background Implantation of Gatekeeper™ prostheses presents an option for the treatment of passive faecal incontinence (FI). Whilst preliminary results are encouraging, long-term data regarding its sustained benefit are limited. The aim of this study was to assess and evaluate the long-term clinical function and quality of life of patients with passive faecal incontinence who were treated with Gatekeeper™ prostheses. Methods This was a single centre, single surgeon retrospective study of prospectively collected clinical data in patients with FI treated between June 2012 and May 2019. Patients with passive FI with symptoms refractory to conservative treatment and endoanal ultrasonography showing intact or disrupted internal anal sphincter were included. Formal clinical and quality of life assessments were carried out using the St. Mark’s Incontinence Score (SMIS) and Faecal Incontinence Quality of Life (FIQoL) questionnaires at baseline, 3 months, 6 months, 12 months and then annually. Endoanal ultrasonography was performed both before and after surgery. Results Forty patients (14 males, 26 females) with a median age of 62.5 (range 33–80) years were treated with the Gatekeeper™ implant. The majority of patients (87.5%) received six implants. There were no peri or post-operative complications. Prosthesis migration was observed in 12.5% patients. The median follow-up duration was 5 years (interquartile range (IQR) 3.25–6.00 years). A sustained improvement in median SMIS and FIQoL scores from baseline to follow-up was noted. Significant differences were observed between the median baseline SMIS score and last follow-up score of 16.00 (IQR 15.00–16.75) to 7.00 (IQR 5.00–8.00) respectively (p < 0.001), a 56.25% decrease. The overall median FIQoL score showed a significant improvement from 7.95 (IQR 7.13–9.48) to 13.15 (IQR 12.00–13.98) (p < 0.001) a 65.40% increase. Conclusions Gatekeeper™ implantation is a safe approach to treating passive FI and is minimally invasive, reproducible and has minimal complications. Long-term sustained clinical improvement is achievable beyond 5 years. Careful patient selection is paramount, as is consistency of technique and follow-up protocol.

Critical appraisal of international guidelines for the management of fecal incontinence in adults: is it possible to define what to do in different clinical scenarios? Tech Coloproctol 2021; 26:1-17. [PMID: 34767095 PMCID: PMC8587500 DOI: 10.1007/s10151-021-02544-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 10/28/2021] [Indexed: 11/10/2022]
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
BACKGROUND External anal sphincter contractility significantly contributes to control the passage of stool. An artificial anal sphincter placed into the intersphincteric space is a safe and effective procedure to treat fecal incontinence, even if its mechanism of action has not been fully elucidated. OBJECTIVE The aim of this study was to evaluate external anal sphincter contractility changes after a self-expandable hyexpan prostheses was implanted into the intersphincteric space of the anal canal and clinical outcomes compared. DESIGN This was a prospective clinical study. SETTINGS The study was conducted at a university teaching hospital. PATIENTS Consecutive patients affected by fecal incontinence for at least 6 months after failure of conservative treatment were included. INTERVENTIONS All of the patients underwent 10-prostheses implantation and were examined preoperatively and postoperatively by endoanal ultrasound and anorectal manometry. MAIN OUTCOME MEASURES Fecal incontinence symptoms were assessed by severity scores. The external anal sphincter muscle tension was calculated using a specific equation. RESULTS Thirty-nine patients (34 women; median age = 68 y) were included in the study; no morbidity was registered. After a median follow-up period of 14 months, both the median maximum voluntary squeeze pressure and the median inner radius of the external anal sphincter significantly increased. A statistically significant increase of external anal sphincter muscle tension was detected. A decrease of any fecal incontinence symptom and an improvement in severity scores were observed at the last follow-up examination. The external anal sphincter contractility was significantly higher in patients reducing incontinence episodes to solid stool by >50% and improving their ability to defer defecation for >15 minutes. LIMITATIONS This was a single-center experience with a relatively small and heterogeneous sample size, patients with a potentially more severe disease because our institution is a referral center, and an absence of quality-of-life evaluation. CONCLUSIONS Artificial anal sphincter implantation improved the external anal sphincter muscle tension; there was a positive correlation between its increase and the clinical outcome.

IMPLANTE DE ESFNTER ANAL ARTIFICIAL AUTOEXPANDIBLE EN PACIENTES CON INCONTINENCIA FECAL MEJORA LA CONTRACTILIDAD DEL ESFNTER ANAL EXTERNO ANTECEDENTES:La contractilidad del esfínter anal externo contribuye significativamente al control del paso de las heces. Un esfínter anal artificial colocado en el espacio interesfinteriano es un procedimiento seguro y eficaz para tratar la incontinencia fecal, incluso si su mecanismo de acción no se ha definido por completo.OBJETIVO:El objetivo de este estudio fue evaluar los cambios en la contractilidad del esfínter anal externo después de la implantación de una prótesis de hyexpan autoexpandible en el espacio interesfinteriano del canal anal y comparar los resultados clínicos.DISEÑO:Estudio clínico prospectivo.ENTORNO CLINICO:El estudio se realizó en un hospital universitario.PACIENTES:Pacientes consecutivos afectados por incontinencia fecal durante al menos 6 meses, tras fracaso de tratamiento conservador.INTERVENCIONES:Todos los pacientes fueron sometidos a la implantación de 10 prótesis, y fueron examinados pre y postoperatoriamente mediante ecografía endoanal y manometría anorrectal.PRINCIPALES MEDIDAS DE VALORACION:Los síntomas de incontinencia fecal se evaluaron mediante puntuaciones de gravedad. La tensión del músculo del esfínter anal externo se calculó mediante una formula específica.RESULTADOS:Treinta y nueve pacientes (34 mujeres; mediana de edad 68 años) fueron incluidos en el estudio; no se registró morbilidad. Después de un período de seguimiento medio de 14 meses, tanto la presión de compresión voluntaria máxima media como el radio interior medio del esfínter anal externo aumentaron significativamente. Se detectó un aumento estadísticamente significativo de la tensión del músculo del esfínter anal externo. En el último examen de seguimiento se observó una disminución de cualquier síntoma de incontinencia fecal y una mejora en las puntuaciones de gravedad. La contractilidad del esfínter anal externo fue significativamente mayor en los pacientes que redujeron los episodios de incontinencia a heces sólidas en más del 50% y mejoraron la capacidad para diferir la defecación durante más de 15 minutos.LIMITACIONES:Experiencia de un solo centro; tamaño de muestra relativamente pequeño y heterogéneo; pacientes con una enfermedad potencialmente más grave porque nuestra institución es un centro de referencia; ausencia de evaluación de la calidad de vida.CONCLUSIONES:La implantación del esfínter anal artificial mejoró la tensión muscular del esfínter anal externo; hubo una correlación positiva entre su aumento y el resultado clínico.

Abstract
Background. We aim to evaluate morphofunctional changes of the sphincter complex after GateKeeper (GK) and SphinKeeper (SK) procedures and correlate these with symptom improvement. Methods. Ten consecutive females undergoing SK implant were age-matched with a cohort of 10 females who previously underwent the GK procedure. Patients in the SK and GK groups underwent implantation of 10 and 6 prostheses, respectively. Muscle tension (Tm), expressed in millinewtons per centimetre squared, mN (cm2)-1, was calculated using the equation Tm = P(ri)(tm)-1, where P is the average maximum squeeze pressure and ri and tm the inner radius and thickness of the external anal sphincter, respectively. The pre- and postimplant changes in Tm and Cleveland Clinic Fecal Incontinence Score (CCFIS) were tested by linear and Poisson regression models, respectively. Results. The CCFIS significantly improved in both groups at 12-month postimplantation. Although not reaching statistical significance, symptom improvement after SK was 33% above that observed after GK (P = .088). Compared to the baseline, a significant increase in Tm was observed in both groups at 12 months (GK, 508.1 [478.8-568.0] vs 864.4 [827.0-885.8] mN (cm2)-1; SK, 528.0 [472.7-564.0] vs 858.6 [828.0-919.6] mN (cm2)-1, P = .005). Compared to the GK group, Tm was significantly higher in patients after SK implant (158.3 mN (cm2)-1 [95% confidence interval, 109.6-207.0]; P < .001), after controlling for baseline values, at 12-month postimplantation. Conclusions. GK and SK are safe and effective treatments for FI with good short-term clinical outcomes. Comparative analysis showed superiority of SK over GK in terms of gain in Tm, with borderline significantly better improvement in symptoms. Larger studies are needed to confirm these findings.

Abstract
BACKGROUND Intersphincteric injectable bulking agents are one of the current treatment options for fecal incontinence, failing behavioral and medical therapy. Gatekeeper showed promising short-term results, but long-term outcomes are unknown. OBJECTIVE The purpose of this study was to clinically evaluate a prospective cohort of fecal incontinence patients up to 36 months after implantation of Gatekeeper. DESIGN This was a prospective clinical study. SETTINGS The study was conducted at a large university tertiary care hospital. PATIENTS Consecutive female patients were eligible if fecal incontinence onset was ≥6 months before the first visit and symptoms were refractory to standard conservative measures. INTERVENTIONS All of the patients underwent implantation of 4 or 6 Gatekeeper prostheses. Three-dimensional endoanal ultrasonography and high-resolution anorectal manometry were performed preoperatively and postoperatively at 2 and 3 months after implantation. MAIN OUTCOME MEASURES The Cleveland Clinic Fecal Incontinence score was calculated at baseline and 1, 3, 12, 24, and 36 months postoperatively. RESULTS Twenty patients (all women; median age, 59 y) were enrolled, and all implants were uneventful. Postoperative endoanal ultrasonography showed normal prosthesis localization in 16 patients (80%). At manometry, mean anal resting pressure significantly improved (57.8 ± 7.5 mm Hg; p = 0.0004). Mean preoperative Cleveland Clinic Fecal Incontinence score was 12.4 ± 1.8, with significant improvements initially documented at 3 months (4.9 ± 1.5; p < 0.0001) and sustained up to 36 months (4.9 ± 1.7; p < 0.0001). Patients receiving only 4 (compared with 6) prostheses and those experiencing pudendal neuropathy (compared with those who did not) showed significantly higher Cleveland Clinic Fecal Incontinence score values in the middle term. LIMITATIONS The study was limited by its small sample size and absence of quality-of-life data. CONCLUSIONS Initial improvements after Gatekeeper implantation for fecal incontinence are sustained in the middle term. Accurate preoperative evaluation of coexistent clinical conditions that may negatively affect outcomes is recommended for patient selection. See Video Abstract at http://links.lww.com/DCR/B109. RESULTADOS A MEDIANO PLAZO EN LA IMPLANTACIÓN DE GATEKEEPER PARA LA INCONTINENCIA FECAL: Los agentes de volumen inyectables interesfintéricos, son opciones actuales de tratamiento para la incontinencia fecal, ante fallas de terapias conductuales y médicas. Gatekeeper mostró resultados prometedores a corto plazo, pero resultados a largo plazo aún son desconocidos.Evaluar clínicamente una cohorte prospectiva de pacientes con incontinencia fecal, hasta 36 meses después de la implantación de Gatekeeper.Estudio clínico prospectivo.El estudio se realizó en un gran hospital universitario de atención terciaria.Fueron elegibles pacientes femeninas consecutivas, si el inicio de la incontinencia fecal, fue al menos 6 meses antes de la primera visita, y que los síntomas fueron refractarios a las medidas conservadoras estandarizadas.Todas las pacientes fueron sometidas a implantación de 4 o 6 prótesis Gatekeeper. Se realizó ecografía endoanal de 3D y manometría anorrectal de alta resolución, antes de la implantación y después a los 2 y 3 meses.Se calculó el puntaje de incontinencia fecal de la Cleveland Clinic al inicio, y a los 1, 3, 12, 24 y 36 meses después de la operación.Se inscribieron veinte pacientes (todas mujeres; con edad media de 59 años), y todos los implantes transcurrieron sin incidentes. La ecografía endoanal postoperatoria, mostró localización normal de la prótesis en 16 (80%) pacientes. A la manometría, la presión media de reposo anal, mejoró significativamente (57.8 ± 7.5 mmHg, p = 0.0004). La puntuación media preoperatoria de la incontinencia fecal de la Cleveland Clinic, fue de 12.35 ± 1.75, con mejoras significativas documentadas inicialmente a los 3 meses (4.9 ± 1.5, p <0.0001) y sostenidas hasta los 36 meses (4.9 ± 1.7, p <0.0001). Los pacientes que recibieron solo 4 prótesis (en comparación con 6) y que padecían neuropatía pudenda (en comparación con aquellas que no la padecían), mostraron valores de puntaje de Incontinencia Fecal de la Clínica Cleveland, significativamente más altos en el mediano plazo.El tamaño pequeño de la muestra y la ausencia de datos en calidad de vida.Las mejoras iniciales después de la implantación de Gatekeeper para la incontinencia fecal, se mantienen en el mediano plazo. Para la selección de pacientes, se recomienda una precisa evaluación preoperatoria de las condiciones clínicas coexistentes, que puedan afectar negativamente los resultados.
