Bowel management for patients with myelodysplasia

State of the Art Bowel Management for Pediatric Colorectal Problems: Spinal Anomalies

BACKGROUND

Patients with spinal abnormalities often struggle with fecal and/or urinary incontinence (up to 87 and 92%, respectively) and require a collaborative approach to bowel management in conjunction.

METHODS

To define existing approaches and propose state-of-the-art bowel management, a literature search was performed using Medline/PubMed, Google Scholar, Cochrane, and EMBASE databases and focusing on the manuscripts published July 2013 and July 2023.

RESULTS

Patients with spinal anomalies have impaired innervation of the rectum and anal canal, decreasing the success rate from laxatives and rectal enemas. Thus, transanal irrigations and antegrade flushes are widely utilized in this group of patients. Based on spinal MRI, the potential for bowel control in these children depends on age, type, and lesion level. On referral for bowel management, a contrast study is performed to assess colonic motility and evacuation of stool, followed by a series of abdominal X-rays to define colonic emptying and adjust the regimen. The options for management include laxatives, rectal enemas, transanal irrigations, antegrade flushes, and the creation of a stoma. Approximately 22-71% of patients achieve social continence dependent on the type and level of the lesion.

CONCLUSION

Patients with spinal anomalies require a thorough assessment for continence potential and stool burden prior to initiation of bowel management. The optimal treatment option is defined according to the patient's age, anatomy, and mobility. The likelihood of independent bowel regimen administration should be discussed with the patients and their caregivers.

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.

Bowel function and care: Guidelines for the care of people with spina bifida

PURPOSE

Bowel dysfunction, such as constipation and fecal incontinence, has a significant impact on health, activities of daily living, and quality of life among people with spina bifida. Secondary complications may result from bowel dysfunction and include urologic dysfunction, loss of skin integrity, shunt (hydrocephalus) function, as well as loss of social opportunities and employability.

METHODS

Using a consensus building methodology, the guidelines for management of bowel dysfunction in spina bifida were written by experts in the field of spina bifida and bowel function and care.

RESULTS

The evidence-based guidelines are presented in table format and provide age-specific recommendations to achieve fecal continence without constipation. Recommended treatments are presented from least to most invasive options. Literature supporting the recommendations and the interval research published to date is also presented.

CONCLUSION

These guidelines present a standardized approach to management of bowel dysfunction in spina bifida. Bowel management in children and young adults with spina bifida is limited by variability in clinical practice and paucity of robust research in neurogenic bowel. Collaborative multi-institutional efforts are needed to overcome research barriers and provide innovative solutions.

Using a Decision Tree to Guide Bowel Management in Spina Bifida

BACKGROUND

When born with spina bifida, there are numerous neurologic disorders that accompany this birth defect, including neurogenic bowel. Proactive, systematic, and rational approaches can lead to continence and a more functional lifestyle [1].

METHODS

Based on the evidence in the literature and expert experience, our approach to bowel management was developed as a step by step, individualized approach. This was converted to a decision tree for easy guidance of treatment decisions. The approach includes teaching patients and families normal bowel function, changes resulting from neurogenic bowel, common pitfalls in bowel management, and techniques that may improve outcomes. The decision tree, starting with dietary management, breaks into a two-fold attack, oral and rectal. Our data as part of the National Spina Bifida Patient Registry (NSBPR) database was compared to public data from the NSBPR.

RESULTS

Preliminary data from the NSBPR in 2011 reported bowel continence in 42.1% (n = 898) compared to our clinical outcomes of 72.1% (n = 43). As the variable of bowel continence was further defined and more patients were enrolled, the clinic results were comparable to the national reports.

CONCLUSION

Consistency among providers and caregivers is critical to evaluating the management of continence in spina bifida. While this protocol warrants further evaluation, it is offered as an evidence-based, step by step, approach to bowel management in spina bifida with good outcomes for patient management.
