Biofeedback in patients with ileoanal pouch dysfunction: a specialist centre experience

Functional Disorders of the Ileal-Anal Pouch: A Systematic Review

BACKGROUND

The IPAA is a boon to patients needing proctocolectomy but maintains per anal function through anatomic and physiologic compromises. The state of pouch function is hard to define because pouch anatomy is not normal and pouch physiology is a distortion of normal defecation. Patients with pouches develop multiple symptoms: some are expected, some are disease related, and some are the result of surgical complications. It is important to understand the cause of pouch-related symptoms so that appropriate management is offered.

OBJECTIVES

The study aimed to review pouch symptoms and discuss their likely cause, review the literature on pouch function and dysfunction, and provide clarity to clear the confusion.

DATA SOURCES

PubMed and Cochrane databases were searched using the terms "ileoanal pouch function" and "ileoanal pouch dysfunction."

STUDY SELECTION

From 1983 to 2023, 553 articles related to "ileoanal pouch function" and 178 related to "ileoanal pouch dysfunction" were reviewed. Nine studies appeared under both headings. Case studies, duplicate publications, and articles concerning pouch diseases were excluded.

MAIN OUTCOME MEASURES

Definitions of pouch function and dysfunction, methods of describing and scoring symptoms, and understanding of expected changes in pouch function given the nature of the surgery.

RESULTS

Twenty-seven studies were reviewed from the ileoanal pouch dysfunction search and 38 from ileoanal pouch function. Three studies tried to define normal pouch function, 10 attempted to measure pouch function, and 4 aimed to score pouch function. Only 3 studies addressed pouch physiology.

LIMITATIONS

A full discussion of pouch dysfunction is limited by the lack of studies focussing on the anatomic and physiologic consequences of turning the terminal ileum into an organ of storage.

CONCLUSIONS

Most studies of pouch function and dysfunction do not consider expected changes in the physiology of defecation that follow restorative proctocolectomy. Thus, most studies of pouch function produce conclusions that lack an important dimension. See video from symposium.

Complications following ileal pouch-anal anastomosis in pediatric ulcerative colitis

Ileal pouch-anal anastomosis (IPAA) is the procedure of choice for reconstruction after total proctocolectomy in pediatric patients with ulcerative colitis. 30-60 % of patients undergoing IPAA will experience a postoperative complication. The primary objective of this article is to address the most common complications specific to IPAA in the pediatric population and provide an up-to-date review of their presentation, risk factors, workup, and management. We also share our preferred approaches to management and prevention of complications, where relevant. We intend to provide a concise review on the topic aimed at pediatric surgeons and healthcare providers involved in the care of this population with the goal of contributing to improved outcomes and patient quality of life.

Dynamic ileal pouch emptying studies

Although much radiologic literature has focused on the short-term post-operative complications associated with ileal pouches, as the number of patients with long-term pouches has grown, there is increasing realization of the functional deficits that may occur long after pouch creation. Dynamic pouch imaging using fluoroscopy and MRI can provide assessment of the underlying causes of symptomatic pouch dysfunction and can provide critical insight to the management of this complex patient population. In this paper, we provide an overview of the unique problems encountered in patients with long-term ileal pouches, and provide an overview of the techniques, interpretation, and reporting for fluoroscopic and MR pouch defecography.

Ileoanal Pouch Syndrome Is Common and Associated With Significant Disability in Patients With Ulcerative Colitis Undergoing IPAA

BACKGROUND

Recently, ileoanal pouch syndrome (IPS) has been proposed and defined according to a series of patient-centered bowel symptoms and consequences after ileoanal pouch surgery.

OBJECTIVE

The purpose of this study was to investigate the prevalence of IPS and the related disability in UC patients undergoing IPAA.

DESIGN

This was a cross-sectional study.

SETTING

This study was conducted in a tertiary center.

PATIENTS

Data of 128 UC-related IPAA from October 2014 to May 2021 were collected.

MAIN OUTCOME MEASURES

Primary outcomes were prevalence of IPS.

RESULTS

One hundred twenty-eight patients were enrolled with a median postoperative follow-up of 2.64 (IQR, 1.31-3.80) years. The prevalence of IPS and its constituent symptoms and consequences are lower for patients with longer follow-up after ileostomy reversal. Fecal incontinence and pad usage had the greatest impact on the quality of life affecting 29% and 31% of patients. IPS group had a significantly higher IBD-Disability Index score compared to the non-IPS group (27.25 vs 12.15, p < 0.001). Multivariate analysis showed that 4 symptoms (fecal incontinence, clustering, fragmentation and incomplete evacuation, and nocturnal symptoms) and 2 consequences (pad usage and negative mental alterations) were associated with increased IBD-Disability Index (p < 0.05). For patients followed-up for >2 years, multivariate analysis showed that male gender (OR, 4.485; 95% CI, 1.354-14.857; p = 0.014), preoperative duration of disease (OR, 1.013; 95% CI, 1.001-1.025; p = 0.031), and postoperative follow-up (OR, 0.462; 95% CI, 0.244-0.876; p = 0.049) were independently associated with IPS.

LIMITATIONS

This is a single-center cross-sectional study rather than a prospective multicenter large longitudinal study.

CONCLUSIONS

IPS is a common situation negatively affecting the quality of life for patients with ulcerative colitis undergoing IPAA, and its rate decreased over time from ileal pouch surgery. See Video Abstract at http://links.lww.com/DCR/C41.

EL SNDROME DEL RESERVORIO ILEOANAL ES COMN Y EST ASOCIADO CON UNA DISCAPACIDAD SIGNIFICATIVA EN PACIENTES CON CU CON RESERVORIO ILEAL Y ANASTOMOSIS RESERVORIOANAL

ANTECEDENTES:Recientemente se propuso y definió el síndrome del reservorio ileoanal de acuerdo con una serie de síntomas intestinales centrados en el paciente y las consecuencias después de la cirugía del reservorio ileoanal.OBJETIVO:El propósito de este estudio fue investigar la prevalencia del síndrome del reservorio ileoanal y la discapacidad relacionada en pacientes con colitis ulcerosa con reservorio ileal y anastomosis reservorio-anal.DISEÑO:Este fue un estudio transversal.ESCENARIO:Este estudio se realizó en un centro terciario.PACIENTES:Se recopilaron datos de 128 pacientes con reservorio ileal por colitis ulcerosa desde octubre de 2014 hasta mayo de 2021.PRINCIPALES MEDIDAS DE RESULTADO:Los resultados primarios fueron la prevalencia del síndrome del reservorio ileoanal.RESULTADOS:Ciento veintiocho pacientes fueron reclutados con una mediana de seguimiento postoperatorio de 2,64 (IQR, 1,31-3,80) años. La prevalencia del síndrome del reservorio ileoanal y sus síntomas y consecuencias constituyentes es menor para los pacientes con un seguimiento más prolongado después de la reversión de la ileostomía. La incontinencia fecal y el uso de compresas tuvieron el mayor impacto en la calidad de vida, afectando al 29% y al 31% de los pacientes. El grupo con síndrome del reservorio ileoanal tuvo una puntuación del índice de discapacidad por enfermedad inflamatoria intestinal significativamente más alta en comparación con el grupo sin síndrome del reservorio ileoanal (27,25 frente a 12,15, p <0,001). El análisis multivariado mostró que 4 síntomas (incontinencia fecal, agrupamiento, fragmentación y evacuación incompleta y síntomas nocturnos) y 2 consecuencias (uso de toallas higiénicas y alteraciones mentales negativas) se asociaron con un aumento del índice de discapacidad por enfermedad inflamatoria intestinal (p <0,05). Para los pacientes seguidos durante más de dos años, el análisis multivariado mostró que el sexo masculino (OR, 4,485; IC 95%, 1,354-14,857; p = 0,014), la duración preoperatoria de la enfermedad (OR, 1,013; IC 95%, 1,001-1,025; p = 0,031) y el seguimiento postoperatorio (OR, 0,462; IC 95%, 0,244-0,876; p = 0,049) se asociaron de forma independiente con el síndrome del reservorio ileoanal.LIMITACIONES:Este es un estudio transversal de un solo centro en lugar de un gran estudio longitudinal prospectivo multicéntrico.CONCLUSIONES:El síndrome del reservorio ileoanal es una situación común que afecta negativamente la calidad de vida de los pacientes con colitis ulcerosa sometidos a anastomosis del reservorio ileal-anal, y su tasa disminuyó con el tiempo a partir de la cirugía del reservorio ileal. El sexo masculino y la mayor duración preoperatoria de la enfermedad son factores de riesgo importantes para el síndrome del reservorio ileoanal.

When pouches cannot empty: a cohort study of the symptoms this causes, the reasons it's happening, and the treatments needed

BACKGROUND

Patients with an ileal pouch have a new system of defecation. The expulsive peristalsis of the rectum is replaced by the inertia of the pouch. Defecation becomes dependent on gravity and patients are prone to inefficient pouch-emptying. Several factors can impact pouch emptying and here we review a series of patients to illustrate these factors and their variable presentations.

METHODS

This is a retrospective, descriptive study of a series of patients who had undergone total proctocolectomy with ileal pouch anal anastomosis and presented with pouch dysfunction. Patients underwent investigations including, pouchoscopy, pouchography and anorectal physiology testing.

RESULTS

There were 34 patients, 18 men, mean age 48.4 years. Thirty-one had a J-pouch and 3 an S-pouch. Twenty-eight had a stapled and 6 a hand-sewn anastomosis. Presenting complaints included difficulty emptying the pouch (n = 17), high stool frequency (n = 8), clinical bowel obstruction (n = 7), and nocturnal incontinence (n = 3). Diagnoses were anal stenosis (11), afferent-limb syndrome (n = 7), pouch twist (n = 4), paradoxical puborectalis contraction (n = 7), efferent-limb spasm/stenosis (n = 2), mega-pouch (n = 3), pouch prolapse (n = 1), and pouch-rectal anastomosis (n = 1). Treatments included anal dilation (n = 11), disimpaction (n = 2), biofeedback (n = 2), pouch excision (n = 2), laparotomy with lysis of adhesions (n = 6), Botox injection into puborectalis (n = 6), catheter drainage (3), and miralax (n = 11). All patients with a stenosis had some improvement after dilation, and surgery restored pouch function.

CONCLUSIONS

Accurate diagnosis and effective treatment of pouch dysfunction is based on an appreciation of pouch physiology, correction of anatomic abnormalities that impair emptying, and management of stool consistency.

Diagnosis and Management of Functional Pouch Disorders: A Systematic Review

BACKGROUND

Functional disorders impart significant morbidity in patients with inflammatory bowel disease who undergo restorative proctocolectomy.

OBJECTIVE

This systematic review aimed to summarize the management strategies for various functional disorders of the pouch.

DATA SOURCES

A database search of PubMed was conducted to identify relevant clinical studies assessing the management of various functional disorders in patients who underwent restorative proctocolectomy.

STUDY SELECTION

Published clinical studies investigating a functional disorder of the pouch in patients who previously underwent a colectomy with ileal pouch-anal anastomosis.

INTERVENTIONS

Restorative proctocolectomy was completed in patients with inflammatory bowel disease or other indications such as a diagnosis of familial adenomatous polyposis.

MAIN OUTCOME MEASURES

The primary outcomes described in this review include the prevalence of functional disorders of the pouch in patients undergoing restorative proctocolectomy and the relevant management strategies.

RESULTS

Ten clinical studies were identified using the predetermined search terms and screened for relevancy to patients with inflammatory bowel disease who previously underwent colectomy with ileal pouch-anal anastomosis. A qualitative summary was developed on the basis of data from these studies and from current guidelines developed for the management of inflammatory bowel disease.

LIMITATIONS

This systematic review is limited by the small number and low quality of the clinical studies included as well as the nonquantitative summary of the findings.

CONCLUSIONS

Functional disorders of the pouch are likely underdiagnosed. Although a source of significant morbidity, these diseases require additional clinical studies to better elucidate effective management strategies.

Complementary and Alternative Medicine in Crohn's Disease

Complementary and alternative medicine (CAM) is a growing entity within inflammatory bowel disease (IBD). CAM includes mind-based therapies, body-based therapies, supplements, vitamins, and probiotics. Limitations currently exist for health care providers as it pertains to IBD and CAM that stem from knowledge gaps, conflicting reports, limited oversight, and a lack of well-organized clinical data. Even without well-described data, patients are turning to these forms of therapy at increasing rates. It is imperative that the ongoing review of CAM therapies is performed, and future trials are performed to better understand efficacy as well as adverse effects related to these therapies.

The pouch behaving badly: management of morbidity after ileal pouch-anal anastomosis

AIM

Ileal pouch-anal anastomosis (IPAA), or a 'pouch', allows restoration of intestinal continuity after proctocolectomy for ulcerative colitis or familial adenomatous polyposis. Most patients have a good long-term outcome after IPAA, but in a significant proportion the functional outcome and quality of life are unsatisfactory. We term this outcome 'the pouch behaving badly'. Managing this, especially one is when unfamiliar with the possible underlying pathologies, is a challenge for both patient and clinician. We aim to outline the clinical approach to the pouch behaving badly, highlighting key aspects of investigation and management.

METHOD

This is a narrative review of the literature covering the investigation and management of postoperative complications and morbidity after IPAA.

RESULTS

Management of the pouch behaving badly requires a careful clinical assessment. The patient may present with multiple symptoms and a clear picture of the symptomatology and past history should be constructed before thorough examination and specialist investigation. We divide the pathology that underlies this clinical scenario into surgical, inflammatory, mechanical, functional and dysplastic causes and outline the investigation and management of each one.

CONCLUSION

The pouch behaving badly is a challenging problem for both patient and clinician. A detailed clinical assessment with careful specialist investigation is key to diagnosing the underlying pathology. We stress the importance of patient-centred care - the aim is to improve quality of life.

Systematic review: Pelvic floor muscle training for functional bowel symptoms in inflammatory bowel disease

BACKGROUND AND AIM

Large bowel functional symptoms are common in patients with inflammatory bowel disease (IBD) who are in disease remission. The efficacy of pelvic floor muscle training for symptoms of evacuation difficulty or fecal incontinence is well established in patients without organic bowel disease but is unknown in these patients. This study aimed to systematically evaluate the published evidence in this group of patients.

METHODS

A systematic review was conducted of articles evaluating pelvic floor muscle training, with or without biofeedback, to improve bowel function in patients with quiescent IBD, including those with an ileoanal pouch. The outcome of interest was improved bowel function measured by bowel diary, patient report, or validated questionnaire in randomized controlled studies, cohort studies, or case series.

RESULTS

Two randomized controlled trials, four retrospective case series, and one prospective study met eligibility criteria. Pelvic floor muscle training for patients with quiescent IBD improved symptoms in 51 of 76 (68%) patients with evacuation difficulty and 20 of 25 (80%) patients with fecal incontinence. Pelvic floor muscle training for patients with an ileoanal pouch, prior to stoma closure, did not appear to reduce the risk or severity of fecal incontinence following stoma closure. Studies were limited by small numbers, study design, methodological quality, and lack of long-term follow-up.

CONCLUSION

Pelvic floor muscle training appears to be of therapeutic value in some patients with quiescent IBD and evacuation difficulty or fecal incontinence. The effectiveness of this approach warrants further investigation.

Gut-Directed Pelvic Floor Behavioral Treatment for Fecal Incontinence and Constipation in Patients with Inflammatory Bowel Disease

BACKGROUND

Patients with inflammatory bowel disease (IBD) often experience functional bowel symptoms despite achieving disease remission. Although behavioral treatment (bowel and pelvic floor muscle retraining) is effective for managing constipation or fecal incontinence in non-IBD patients, there is limited evidence for its efficacy in patients with quiescent inflammatory bowel disease. The aim of this study was to evaluate the outcome of gut-directed behavioral treatment, including pelvic floor muscle training, for symptoms of constipation or fecal incontinence in patients with IBD in disease remission.

METHODS

The outcome of consecutive patients with IBD in remission and symptoms of constipation or fecal incontinence was evaluated. Patients referred to a multidisciplinary gastroenterology clinic underwent gut-directed behavioral treatment, including pelvic floor muscle training. The primary outcome was patient-reported rating of change in symptoms on a 7-point Likert scale at the completion of treatment.

RESULTS

Forty IBD patients (median age, 35 years; 80% female; 24 Crohn's disease [CD], 12 ulcerative colitis [UC], 4 UC with ileoanal pouch) with ongoing symptoms of constipation (55%) or fecal incontinence (45%), despite drug therapy, were included. The median symptom duration at referral was 2 years. Thirty-five (87%) completed treatment with a median of 2 sessions. Improvement of "6 = much better" or "7 = very much better" was reported by 77% (17/22) with fecal incontinence and 83% (15/18) with constipation. Improvement occurred irrespective of IBD diagnosis, previous perianal fistulae, colorectal surgery, presence of an ileoanal pouch, or past obstetric trauma.

CONCLUSIONS

Behavioral treatment effectively improves functional gut symptoms in a large majority of patients who are in IBD disease remission and who have not responded to drug therapy. 10.1093/ibd/izy344_video1 izy344.video1 5968879349001.

Current perspectives on the diagnosis and management of functional anorectal disorders in patients with inflammatory bowel disease

Despite advances in inflammatory bowel disease (IBD) therapies, a significant proportion of patients with quiescent disease experience persistent, debilitating symptoms of faecal incontinence (FI), urgency and defaecatory disorders due to anorectal dysfunction. Such symptoms are often underreported or misdiagnosed and can lead to potentially premature treatment 'escalation' and under-utilisation of pelvic floor investigations. In this review article, we consider putative pathophysiological post-inflammatory changes resulting in altered anorectal sensitivity, motility and neuromuscular coordination and how this may drive symptoms in quiescent IBD. Finally, we discuss a pragmatic approach to investigating and managing anorectal dysfunction and highlight areas for future research for this often-neglected group of patients.
