Neurogenic Bowel Dysfunction in Patients with Spinal Cord Injury and Multiple Sclerosis-An Updated and Simplified Treatment Algorithm

Neurogenic bowel dysfunction (NBD) is a common condition in individuals with spinal cord injury (SCI) or multiple sclerosis (MS). It usually entails constipation, difficult evacuation of the rectum, and fecal incontinence (FI); often in combination. It is highly burdensome for affected patients and is correlated with poor quality of life. The current treatment algorithm, or treatment pyramid, does not completely correspond to actual clinical practice, and the known and classical pyramid contains both treatments still in their experimental stage as well as several treatments which are not available at all treatment centers. Thus, an updated treatment algorithm is called upon, and the authors of this paper therefore propose a simplified version of the treatment pyramid, aiming to guide clinicians in treating NBD.

Neurogenic Bowel Dysfunction in Children and Adolescents

Neurogenic/neuropathic bowel dysfunction (NBD) is common in children who are affected by congenital and acquired neurological disease, and negatively impacts quality of life. In the past, NBD received less attention than neurogenic bladder, generally being considered only in spina bifida (the most common cause of pediatric NBD). Many methods of conservative and medical management of NBD are reported, including relatively recently Transanal Irrigation (TAI). Based on the literature and personal experience, an expert group (pediatric urologists/surgeons/gastroenterologists with specific experience in NBD) focused on NBD in children and adolescents. A statement document was created using a modified Delphi method. The range of causes of pediatric NBD are discussed in this paper. The various therapeutic approaches are presented to improve clinical management. The population of children and adolescents with NBD is increasing, due both to the higher survival rate and better diagnosis. While NBD is relatively predictable in producing either constipation or fecal incontinence, or both, its various effects on each patient will depend on a wide range of underlying causes and accompanying comorbidities. For this reason, management of NBD should be tailored individually with a combined multidisciplinary therapy appropriate for the status of the affected child and caregivers.

Pharmacological Management of Neurogenic Bowel Dysfunction after Spinal Cord Injury and Multiple Sclerosis: A Systematic Review and Clinical Implications

Neurogenic bowel dysfunction (NBD) is a common problem for people with spinal cord injury (SCI) and multiple sclerosis (MS), which seriously impacts quality of life. Pharmacological management is an important component of conservative bowel management. The objective of this study was to first assemble a list of pharmacological agents (medications and medicated suppositories) used in current practice. Second, we systematically examined the current literature on pharmacological agents to manage neurogenic bowel dysfunction of individuals specifically with SCI or MS. We searched Medline, EMBASE and CINAHL databases up to June 2020. We used the GRADE System to provide a systematic approach for evaluating the evidence. Twenty-eight studies were included in the review. We found a stark discrepancy between the large number of agents currently prescribed and a very limited amount of literature. While there was a small amount of literature in SCI, there was little to no literature available for MS. There was low-quality evidence supporting rectal medications, which are a key component of conservative bowel care in SCI. Based on the findings of the literature and the clinical experience of the authors, we have provided clinical insights on proposed treatments and medications in the form of three case study examples on patients with SCI or MS.

[Anorectal disorders in patients with multiple sclerosis: Physiopathology, prevalence, impact, and management]

OBJECTIVE

Neurogenic bowel disorders (NBD) are frequently observed in patients with multiple sclerosis (MS); the prevalence of constipation is estimated to be 35-54 % and fecal incontinence between 29 and 51 % (LE 4). They contribute to the deterioration of patients' quality of life (LE 4). The aim of this article is to review the literature on the physiopathology, prevalence, impact, and management of bowel disorders in patients with MS in order to educate caregivers about their existence and thus help them to optimize therapeutic choices.

MATERIALS AND METHODS

A bibliographic search was conducted between 2000 and 2019 and 31 relevant scientific articles were selected. Relevant references were subsequently added, bringing the total to 50 articles. A level of scientific evidence (LE) was assigned to each article, except for literature reviews.

RESULTS

The origin of NBD is multifactorial and includes impairment of neurological pathways, polypharmacy, behavioural disorders, and loss of autonomy (LE 4). Patients with MS should be questioned about their bowel habits and, in cases of proven NBD, specific management options should be offered. The first step concerns the dietary and lifestyle rules associated with the use of laxatives, suppositories, and/or enemas (LE 4). In the event of failure, therapies such as abdominal massages (LE 1 and 2), biofeedback and transanal irrigation can be proposed (LE 4). Anterograde colonic irrigation may also be an option (LE 4). The efficacy of stimulating the posterior tibial nerve needs to be proven (LE 4). The implantation of a sacral neuromodulation device is, for the moment, difficult due to the impossibility of performing a spinal magnetic resonance imaging during follow-up. A stoma improves the quality of life of patients and should not be proposed too late.

CONCLUSION

Effective treatment of NBD improves the quality of life of patients and reduces the incidence of bladder disorders (LE 4).

Development and Evaluation of a Protocol to Manage Fecal Incontinence in the Patient with Cancer

Fecal incontinence is an important yet often overlooked clinical problem in the care of patients with cancer. This paper presents a protocol for the assessment and management of this distressing symptom. The objective of the protocol is to regulate bowel motion, thereby minimizing fecal incontinence and improving patients’ physical functioning, self-esteem, dignity, and quality of life. A comprehensive assessment addressing the patient's physical status, previous elimination routines, dietary habits, and medications provides the foundation for successful management. Components of the intervention include dietary modification, Pharmacotherapy with laxatives and suppositories, and attention to routines that capitalize on the normal, involuntary gastrointestinal reflexes. Promotion of normal bowel elimination patterns, positioning, and comprehensive patient teaching and support are also critical components of the intervention. Our experience with this protocol and the outcomes achieved in a small series of patients are discussed.

Management of faecal incontinence and constipation in adults with central neurological diseases

BACKGROUND

People with central neurological disease or injury have a much higher risk of both faecal incontinence and constipation than the general population. There is often a fine line between the two symptoms, with any management intended to ameliorate one risking precipitating the other. Bowel problems are observed to be the cause of much anxiety and may reduce quality of life in these people. Current bowel management is largely empirical, with a limited research base. This is an update of a Cochrane review first published in 2001 and subsequently updated in 2003 and 2006. The review is relevant to individuals with any disease directly and chronically affecting the central nervous system (post-traumatic, degenerative, ischaemic or neoplastic), such as multiple sclerosis, spinal cord injury, cerebrovascular disease, Parkinson's disease and Alzheimer's disease.

OBJECTIVES

To determine the effects of management strategies for faecal incontinence and constipation in people with a neurological disease or injury affecting the central nervous system.

SEARCH METHODS

We searched the Cochrane Incontinence Group Trials Register (searched 8 June 2012), which includes searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and MEDLINE In-Process as well as handsearching of journals and conference proceedings; and all reference lists of relevant articles.

SELECTION CRITERIA

Randomised and quasi-randomised trials evaluating any type of conservative or surgical intervention for the management of faecal incontinence and constipation in people with central neurological disease or injury were selected. Specific therapies for the treatment of neurological diseases that indirectly affect bowel dysfunction were also considered.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed the risk of bias of eligible trials and independently extracted data from the included trials using a range of pre-specified outcome measures.

MAIN RESULTS

Twenty trials involving 902 people were included. Oral medications There was evidence from individual small trials that people with Parkinson's disease had a statistically significant improvement in the number of bowel motions or successful bowel care routines per week when fibre (psyllium) (mean difference (MD) -2.2 bowel motions, 95% confidence interval (CI) -3.3 to -1.4) or oral laxative (isosmotic macrogol electrolyte solution) (MD 2.9 bowel motions per week, 95% CI 1.48 to 4.32) are used compared with placebo. One trial in people with spinal cord injury showed statistically significant improvement in total bowel care time comparing intramuscular neostigmine-glycopyrrolate (anticholinesterase plus an anticholinergic drug) with placebo (MD 23.3 minutes, 95% CI 4.68 to 41.92).Five studies reported the use of cisapride and tegaserod in people with spinal cord injuries or Parkinson's disease. These drugs have since been withdrawn from the market due to adverse effects; as they are no longer available they have been removed from this review. Rectal stimulants One small trial in people with spinal cord injuries compared two bisacodyl suppositories, one polyethylene glycol-based (PGB) and one hydrogenated vegetable oil-based (HVB). The trial found that the PGB bisacodyl suppository significantly reduced the mean defaecation period (PGB 20 minutes versus HVB 36 minutes, P < 0.03) and mean total time for bowel care (PGB 43 minutes versus HVB 74.5 minutes, P < 0.01) compared with the HVB bisacodyl suppository.Physical interventions There was evidence from one small trial with 31 participants that abdominal massage statistically improved the number of bowel motions in people who had a stroke compared with no massage (MD 1.7 bowel motions per week, 95% CI 2.22 to 1.18). A small feasibility trial including 30 individuals with multiple sclerosis also found evidence to support the use of abdominal massage. Constipation scores were statistically better with the abdominal massage during treatment although this was not supported by a change in outcome measures (for example the neurogenic bowel dysfunction score).One small trial in people with spinal cord injury showed statistically significant improvement in total bowel care time using electrical stimulation of abdominal muscles compared with no electrical stimulation (MD 29.3 minutes, 95% CI 7.35 to 51.25).There was evidence from one trial with a low risk of bias that for people with spinal cord injury transanal irrigation, compared against conservative bowel care, statistically improved constipation scores, neurogenic bowel dysfunction score, faecal incontinence score and total time for bowel care (MD 27.4 minutes, 95% CI 7.96 to 46.84). Patients were also more satisfied with this method.Other interventions In one trial in stroke patients, there appeared to be a short term benefit (less than six months) to patients in terms of the number of bowel motions per week with a one-off educational intervention from nurses (a structured nurse assessment leading to targeted education versus routine care), but this did not persist at 12 months. A trial in individuals with spinal cord injury found that a stepwise protocol did not reduce the need for oral laxatives and manual evacuation of stool.Finally, one further trial reported in abstract form showed that oral carbonated water (rather than tap water) improved constipation scores in people who had had a stroke.

AUTHORS' CONCLUSIONS

There is still remarkably little research on this common and, to patients, very significant issue of bowel management. The available evidence is almost uniformly of low methodological quality. The clinical significance of some of the research findings presented here is difficult to interpret, not least because each intervention has only been addressed in individual trials, against control rather than compared against each other, and the interventions are very different from each other.There was very limited evidence from individual trials in favour of a bulk-forming laxative (psyllium), an isosmotic macrogol laxative, abdominal massage, electrical stimulation and an anticholinesterase-anticholinergic drug combination (neostigmine-glycopyrrolate) compared to no treatment or controls. There was also evidence in favour of transanal irrigation (compared to conservative management), oral carbonated (rather than tap) water and abdominal massage with lifestyle advice (compared to lifestyle advice alone). However, these findings need to be confirmed by larger well-designed controlled trials which should include evaluation of the acceptability of the intervention to patients and the effect on their quality of life.

Neurogenic bowel management after spinal cord injury: a systematic review of the evidence

STUDY DESIGN

Randomized-controlled trials (RCTs), prospective cohort, case-control, pre-post studies, and case reports that assessed pharmacological and non-pharmacological intervention for the management of the neurogenic bowel after spinal cord injury (SCI) were included.

OBJECTIVE

To systematically review the evidence for the management of neurogenic bowel in individuals with SCI.

SETTING

Literature searches were conducted for relevant articles, as well as practice guidelines, using numerous electronic databases. Manual searches of retrieved articles from 1950 to July 2009 were also conducted to identify literature.

METHODS

Two independent reviewers evaluated each study's quality, using Physiotherapy Evidence Database scale for RCTs and Downs and Black scale for all other studies. The results were tabulated and levels of evidence assigned.

RESULTS

A total of 2956 studies were found as a result of the literature search. On review of the titles and abstracts, 57 studies met the inclusion criteria. Multifaceted programs are the first approach to neurogenic bowel and are supported by lower levels of evidence. Of the non-pharmacological (conservative and non-surgical) interventions, transanal irrigation is a promising treatment to reduce constipation and fecal incontinence. When conservative management is not effective, pharmacological interventions (for example prokinetic agents) are supported by strong evidence for the treatment of chronic constipation. When conservative and pharmacological treatments are not effective, surgical interventions may be considered and are supported by lower levels of evidence in reducing complications.

CONCLUSIONS

Often, more than one procedure is necessary to develop an effective bowel routine. Evidence is low for non-pharmacological approaches and high for pharmacological interventions.

Neurogenic colorectal and pelvic floor dysfunction

Constipation and faecal incontinence are common symptoms among patients with spinal cord injury (SCI), myelomeningocoele (MMC), multiple sclerosis (MS), Parkinson's disease (PD) and stroke. Faecal incontinence in SCI, MMC and MS is mainly due to abnormal rectosigmoid compliance and rectoanal reflexes, loss of rectoanal sensibility and loss of voluntary control of the external anal sphincter. Constipation in SCI, MMC and MS is probably due to immobilisation, abnormal colonic contractility, tone and rectoanal reflexes or side effects from medication. In PD, dystonia of the external anal sphincter causes difficult rectal evacuation and the loss of dopaminergic neurons in the enteric nervous system probably causes slow-transit constipation. Changes after stroke remain to be studied. Though dietary adjustments, oral laxatives, suppositories and other conservative treatment modalities are commonly used, evidence for their use in patients with central neurological disorders is scarce. For patients with severe symptoms trans-anal irrigation, the Malone appendicostomy or a colostomy can be recommended.

Progressive protocol in the bowel management of spinal cord injuries

Research into bowel management in spinal cord injury is sparse. Specifically, the use of laxatives in this group, while widespread, is not supported by research evidence. A prospective study in which baseline and intervention data were collected from each subject was undertaken with 17 individuals. The baseline was the routine method of bowel management in the study unit. The intervention was the use of a progressive protocol which allowed the use of physical interventions and rectal stimulants prior to the use of laxative therapy if required. Though the response of individuals varied, the number of successful bowel management episodes employing laxatives was significantly less in the intervention phase, the proportion of glycerine suppository uses which were successful was significantly greater, the use of manual evacuation was significantly reduced and the duration of bowel management episodes was significantly less. These findings suggest that use of laxatives in bowel management is not essential for all newly spinal cord injured individuals, while the use of physical interventions in this population may be beneficial. The variable response of individuals to the progressive protocol highlights the need for individual assessment in the area of bowel. The findings of this small study must be validated by a larger study.

Management of faecal incontinence and constipation in adults with central neurological diseases

People with neurological disease have a much higher risk of both faecal incontinence and constipation than the general population. There is often a fine line between the two conditions, with any management intended to ameliorate one risking precipitating the other. Bowel problems are observed to be the cause of much anxiety and may reduce quality of life in these people. Current bowel management is largely empirical with a limited research base.

OBJECTIVES

To determine the effects of management strategies for faecal incontinence and constipation in people with neurological diseases affecting the central nervous system.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Trials Register (searched 26 January 2005), the Cochrane Central Register of Controlled Trials (Issue 2, 2005), MEDLINE (January 1966 to May 2005), EMBASE (January 1998 to May 2005) and all reference lists of relevant articles.

SELECTION CRITERIA

All randomised or quasi-randomised trials evaluating any types of conservative or surgical measure for the management of faecal incontinence and constipation in people with neurological diseases were selected. Specific therapies for the treatment of neurological diseases that indirectly affect bowel dysfunction were also considered.

DATA COLLECTION AND ANALYSIS

Two reviewers assessed the methodological quality of eligible trials and two reviewers independently extracted data from included trials using a range of pre-specified outcome measures.

MAIN RESULTS

Ten trials were identified by the search strategy, most were small and of poor quality. Oral medications for constipation were the subject of four trials. Cisapride does not seem to have clinically useful effects in people with spinal cord injuries (three trials). Psyllium was associated with increased stool frequency in people with Parkinson's disease but did not alter colonic transit time (one trial). Prucalopride, an enterokinetic did not demonstrate obvious benefits in this patient group (one study). Some rectal preparations to initiate defaecation produced faster results than others (one trial). Different time schedules for administration of rectal medication may produce different bowel responses (one trial). Mechanical evacuation may be more effective than oral or rectal medication (one trial). There appears to be a benefit to patients in one-off educational interventions from nurses. The clinical significance of any of these results is difficult to interpret.

AUTHORS' CONCLUSIONS

There is still remarkably little research on this common and, to patients, very significant condition. It is not possible to draw any recommendation for bowel care in people with neurological diseases from the trials included in this review. Bowel management for these people must remain empirical until well-designed controlled trials with adequate numbers and clinically relevant outcome measures become available.

Long-term results for Malone antegrade continence enema for adults with neurogenic bowel disease

OBJECTIVES

To determine the long-term outcomes from the Malone antegrade continence enema (ACE) procedure in adult neurogenic patients.

METHODS

A retrospective review of adult patients who underwent the ACE procedure for neurogenic bowel was done. Patients were studied if they had follow-up of greater than 4 years. We compared pre-ACE and post-ACE toileting times, bowel continence status, and complications, and elicited patient subjective satisfaction with their quality of life.

RESULTS

Six patients were available for study. Mean age was 35 years with a mean follow-up of 4.5 years. Urinary diversion was done in 5 patients. Pre-ACE toileting time was 190 +/- 45 minutes versus post-ACE toileting time of 28 +/- 20 minutes (P <0.001). Four of six patients pre-ACE were incontinent of stool per rectum compared with 1 of these 4 patients post-ACE (P = 0.03). Five patients were continent of stool per ACE stoma. Four patients (67%) had complications. Three of five patients (60%) who underwent synchronous urinary diversion required postoperative re-exploration. Five patients (83%) were satisfied with their outcome and rated their quality of life higher after the ACE procedure compared with pre-ACE.

CONCLUSIONS

The ACE procedure is effective in the long-term management of adult neurogenic bowel. The complication and re-exploration rates are high. Patients must be properly selected to determine appropriate motivation.

A bibliography of cost-effectiveness practices in physical medicine and rehabilitation: AAPM&R white paper

Cost-effectiveness studies attempt to determine the ratio of costs to outcomes of a particular intervention or treatment and to compare a standard intervention with an alternative intervention to determine if the alternative is more cost effective. The goal is to establish priorities for the resources allocation and to decide among alternative interventions for the same medical condition. The global process of rehabilitation does not usually lend itself to cost-effective analysis (due to the complex set of treatments provided) but rather to specific interventions and specific aspects of outcome. The American Academy of Physical Medicine and Rehabilitation has published a cost effectiveness annotated bibliography on the Internet (http://www.aapmr.org/memphys/cebfinala.htm) that identifies 132 studies in the literature that meet specified criteria and are related to the field of rehabilitation. This White Paper attempts to interpret and synthesize the studies in that bibliography that relate to stroke, spinal cord injury (SCI), orthopedic conditions, pain syndromes, amputations, and traumatic brain injury (TBI). Most studies support the cost effectiveness of care for stroke and SCI in dedicated units or centers rather than in a general medical unit. Studies also support back programs and revascularization procedures in limb ischemia. Studies in TBI underscore the significant financial resources for the care of these patients as well as the potential benefit from rehabilitation services even in the most severely injured. Further high quality research in this area is needed.

Management of faecal incontinence and constipation in adults with central neurological diseases

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Trials Register, the Cochrane Controlled Trials Register, MEDLINE, EMBASE and all reference lists of relevant articles. Date of the most recent searches: May 2000.

SELECTION CRITERIA

All randomised or quasi-randomised trials evaluating any types of conservative, or surgical measure for the management of faecal incontinence and constipation in people with neurological diseases were selected. Specific therapies for the treatment of neurological diseases that indirectly affect bowel dysfunction have also been considered.

DATA COLLECTION AND ANALYSIS

Malone antegrade continence enema for adults with neurogenic bowel disease

PURPOSE

We describe the outcomes of adults with neurogenic bowel disease who underwent a Malone antegrade continence enema procedure with or without concomitant urinary diversion.

MATERIALS AND METHODS

Consecutive adult patients with neurogenic bowel disease who underwent an antegrade continence enema procedure (continent catheterizable appendicocecostomy for fecal impaction) were retrospectively reviewed.

RESULTS

Of the 7 patients who underwent an antegrade continence enema synchronous urinary procedure (ileal conduit, augmentation ileocystoplasty with continent catheterizable abdominal stoma or augmentation ileocystoplasty) was also performed in 6. Mean patient age was 32 years and mean followup was 11 months. Of the 7 patients 6 who self-administered antegrade continence enemas regularly were continent of stool per rectum and appendicocecostomy, using the appendicocecostomy as the portal for antegrade enemas. All 6 compliant patients reported decreased toileting time and improved quality of life. Preoperative autonomic dysreflexia resolved postoperatively in 3 patients. All urinary tracts were stable. In 4 patients 5 complications occurred, including antegrade continence enema stomal stenosis requiring appendicocutaneous revision (1), antegrade continence enema stomal stenosis requiring dilation (1), superficial wound infection (1), small bowel obstruction requiring lysis of adhesions (1) and urinary incontinence (1 who underwent continent urinary diversion).

CONCLUSIONS

Patients with neurogenic bladder and bowel disease may benefit from antegrade continence enema performed synchronously with a urinary procedure. Antegrade continence enema may be indicated alone for neurogenic bowel. Patient selection is important.

Pharmacologically initiated defecation for persons with spinal cord injury: effectiveness of three agents

OBJECTIVE

To compare the effectiveness of hydrogenated vegetable oil-based bisacodyl (HVB) suppositories, polyethylene glycol-based bisacodyl (PGB) suppositories, and polyethylene glycol-based, glycerine, docusate sodium mini-enemas (TVC) in subjects with upper motor neuron spinal cord lesions.

STUDY DESIGN

Prospective randomized double blind. Fifteen subjects received one of 3 HVB and 3 PGB suppositories in randomized sequence for each of six scheduled bowel care sessions. Additionally, 10 subjects received 3 TVC. The analysis used timed events that divided the bowel care sessions into discrete intervals. The analysis also compared digital simulations, incontinence, and quantity of stool. Wilcoxon rank sum tests and paired t tests were used to compare the means of intervals during bowel care initiated by HVB, PGB, and TVC.

RESULTS

(means in minutes and p values): Time to Flatus-HVB, 32; PGB, 15; TVC, 15; p < .026, HVB-PGB; p < .983, PGB-TVC; Flatus to Stool Flow-HVB, 6.7; PGB, 5.5; TVC, 3.9; p < .672, HVB-PGB; p < .068, PGB-TVC; Defecation Period-HVB, 36; PGB, 20; TVC, 17; p < .037, HVB-PGB; p < .479, PGB-TVC; Wait Until Transfer-HVB, 10.9; PGB, 10.7; TVC, 7.4; p < .932, HVB-PGB; p < .043, PGB-TVC; Total Time for the bowel program-HVB, 74.5; PGB, 43; TVC, 37; p < .010, HVB-PGB; p < .458, PGB-TVC; percent incidence of incontinence between bowel care sessions-HVB, .067; PGB, .067; TVC, .033; p < 1.0, HVB-PGB; p < .678, PGB-TVC; amount of stool produced-HVB, 3.30; PGB, 3.49; TVC, 3.38; p < .276, HVB-PGB; p < .630, PGB-TVC; average number of digital stimulations per bowel care procedure-HVB, 4.4; PGB, 4.1; TVC, 3.8; p < .411, HVB-PGB; p < .293, PGB-TVC; time per digital stimulation in seconds-HVB, 107; PGB, 40; TVC, 83; p < .149, HVB-PGB; p < .352, PGB-TVC; and the total time, in minutes, spent performing digital stimulations during bowel care-HVB, 10.0; PGB, 2.7; TVC, 5.9; p < .151, HVB-PGB; p < .325, PGB-TVC.

CONCLUSION

Bowel care took less time when initiated with the PGB bisacodyl suppository or TVC mini-enema as compared with the HVB bisacodyl suppository (p < .01).

The malone antegrade continence enema combined with urinary diversion in adult neurogenic patients: early results

OBJECTIVES

Patients with neurogenic voiding dysfunction often have coexisting neurogenic bowel problems. Impaired bowel evacuation is a cause of major morbidity and impaired lifestyle for these patients. The Malone antegrade continence enema (ACE) performed synchronously with a urinary continence procedure has been successful in pediatric patients. We report early experience combining the ACE with a urinary continence procedure in adult neurogenic patients.

METHODS

Adult patients with neurogenic voiding dysfunction and impaired bowel evacuation refractory to conservative management underwent a urinary continence procedure synchronously with an ACE.

RESULTS

Two patients have undergone the procedure. One patient chose a continent catheterizable supravesical bladder augmentation, whereas the other patient chose an ileal conduit. Both patients had a separate appendiceal stoma for their ACE. Both patients are continent of stool at their appendiceal stoma and per rectum. Both patients have stabilized their urinary tracts. Complications were minimal.

CONCLUSIONS

The ACE may benefit adult patients with impaired bowel evacuation and may be combined with a urinary continence procedure. Further study of the ACE is warranted.

Neurogenic bowel dysfunction after spinal cord injury: clinical evaluation and rehabilitative management

Neurogenic bowel dysfunction (NBD) is one of many impairments that result from spinal cord injury (SCI). The experience of persons with SCI reveals that the risk and occurrence of fecal incontinence and difficulty with evacuation are particularly significant life-limiting problems. This review relates the anatomy and physiology of colon function to the specific pathophysiology that detracts from the quality of life of persons after SCI. There are two patterns of NBD after SCI: the upper motor neuron bowel, which results from a spinal cord lesion above the sacral level, and the lower motor neuron bowel, which results from a lesion to the sacral spinal cord, roots, or peripheral nerve innervation of the colon. Rehabilitation evaluation consists of a comprehensive history and examination to define impairments, disabilities, and handicaps pertinent to NBD. Rehabilitation goals include continence of stool, simple willful independent defecation, and prevention of gastrointestinal complications. Intervention consists of derivation and implementation of an individualized person-centered bowel program, which may include diet, oral/rectal medications, equipment, and scheduling of bowel care. Bowel care is a procedure devised to initiate defecation and accomplish fecal evacuation. Digital-rectal stimulation is a technique utilized during bowel care to open the anal sphincter and facilitate reflex peristalsis. Recent advances in rehabilitation practices, equipment, pharmacology, and surgery have offered patients new bowel program alternatives. Interdisciplinary development of solutions for problems of NBD are evolving rapidly.

Do rehabilitation patients continue prescribed bowel medications after discharge?

An exploratory descriptive study was conducted to address the use of bowel medications 1 month after discharge from an inpatient rehabilitation center and the rationale for making changes from bowel medications prescribed at discharge. At discharge, 66% of the 114 participants took bowel medications, but 1 month later, 42% did. Stimulant laxatives accounted for nearly half the medications taken at each point. Most of the patients who made medication changes reduced the prescribed dose or altogether discontinued taking the prescribed medication. In response to open-ended questions about changes, participants gave reasons related to physiology and personal preference. Anticipating that many patients will change their bowel medications after discharge, practitioners need to consider patients' preferences and teach patients how to adjust their medications correctly.
