Assessment of neurogenic bowel dysfunction impact after spinal cord injury using the International Classification of Functioning, Disability and Health

The Malone antegrade continence enema adapting a transanal irrigation system in patients with neurogenic bowel dysfunction

INTRODUCTION

Patients with severe neurogenic bowel dysfunction (NBD) may undergo the Malone antegrade continence enema (MACE) surgery to perform antegrade bowel irrigation (ABI). The standard approach may be prevented by a previous appendectomy or complicated by appendicular stenoses and/or stomal leakages. We present the experience by our tertiary referral center for NBD, adopting a modified surgical technique, based on a neoappendix with the terminal ileum to preserve the natural anti-reflux mechanism of the ileocecal valve and avoid stool leakage, and a largely available transanal irrigation (TAI) system to catheterize the neoappendix and perform ABI.

CASE PRESENTATION

Three individuals with NBD successfully underwent our modified MACE program. Case 1 had cauda equina syndrome. He underwent surgery at 40. Case 2 was a man who suffered from spinal cord dysfunction due to acute disseminated encephalomyelitis, functionally T12 AIS B, at 57. Case 3 was a man with traumatic L1 AIS B paraplegia. At 60 he underwent surgery after 29 years since the injury. He needed a surgical revision due to a postoperative subcutaneous infection. After 121, 84 and 14 months from surgery, the three individuals performed ABI every 2 days, presented functional stomas, had no fecal incontinence, and reported an NBD score of 6, compared to 40, 33 and 35 pre-operatively.

DISCUSSION

To our knowledge, this is the first report of MACE combining a tapered terminal ileum conduit and an adapted TAI system. Our approach proved to be a safe and effective strategy for severe NBD avoiding a colostomy.

The Addition of Transdermal Delivery of Neostigmine and Glycopyrrolate by Iontophoresis to Thrice Weekly Bowel Care in Persons with Spinal Cord Injury: A Pilot Study

Persons with spinal cord injury (SCI) have neurogenic bowel disorders characterized by difficulty with evacuation (DWE), fecal incontinence, and discoordination of defecation. Six medically stable in-patients with SCI with a mean age of 57 ± 10 years (range: 39–66 years) and time since injury of 18 ± 17 years (range: 3–47 years) were investigated. Standard of care (SOC) for bowel care was followed by two weeks of SOC plus neostigmine (0.07 mg/kg) and glycopyrrolate (0.014 mg/kg) administered transcutaneously by iontophoresis thrice weekly for two weeks while patients continued to receive SOC. The primary endpoint was time to bowel evacuation. Body weights and abdominal radiographs were obtained. Ten questions related to bowel function and the Treatment Satisfaction Questionnaire for Medication were acquired after each arm. Bowel evacuation time decreased after the dual drug intervention arm (106.9 ± 68.4 vs. 40.8 ± 19.6 min; p < 0.0001). Body weight decreased (2.78 ± 0.98 kg; p < 0.0001), a finding confirmed on abdominal radiograph. Both questionnaires demonstrated improvement after the dual drug intervention arm. No major adverse events occurred. The addition of neostigmine and glycopyrrolate by transcutaneous administration to SOC for bowel care in persons with SCI and DWE resulted in the safe, effective, and predictable bowel evacuation with subjective improvement in bowel care.

Electroacupuncture at Zusanli (ST36) Repairs Interstitial Cells of Cajal and Upregulates c-Kit Expression in Rats with SCI-Induced Neurogenic Bowel Dysfunction

Background

Electroacupuncture (EA) could improve colonic transit activity in rats with neurogenic bowel dysfunction (NBD) caused by spinal cord injury (SCI). The function of interstitial cells of Cajal (ICCs) and c-Kit expression may play essential roles in this process. Material and Methods. Thirty-six Sprague Dawley rats were randomized to the sham group, the SCI group, or the SCI + EA group (bilateral Zusanli, 30 min/day, 14 days). Changes in the ultrastructural morphology of ICCs were observed. The c-Kit expression on different levels was analyzed by immunohistochemistry, Western blotting, and RT-qPCR, respectively.

Results

Abnormal morphology of ICCs and downregulation of the c-Kit expression occurred after SCI. While the number of ICCs was increased, the ultrastructural morphology was improved significantly in EA rats. They also showed better improvement in c-Kit expression at both protein and gene levels.

Conclusion

Abnormal ICCs in colon tissues and the downregulated expression of c-Kit could be observed after SCI. EA at Zusanli (ST36) could improve the colon function by repairing the morphology and increasing the number of ICCs and upregulating c-Kit expression.

Diet in neurogenic bowel management: A viewpoint on spinal cord injury

The aim of this review is to offer dietary advice for individuals with spinal cord injury (SCI) and neurogenic bowel dysfunction. With this in mind, we consider health conditions that are dependent on the level of lesion including skeletal muscle atrophy, autonomic dysreflexia and neurogenic bladder. In addition, SCI is often associated with a sedentary lifestyle, which increases risk for osteoporosis and diseases associated with chronic low-grade inflammation, including cardiovascular and chronic kidney diseases. The Mediterranean diet, along with exercise and dietary supplements, has been suggested as an anti-inflammatory intervention in individuals with SCI. However, individuals with chronic SCI have a daily intake of whole fruit, vegetables and whole grains lower than the recommended dietary allowance for the general population. Some studies have reported an increase in neurogenic bowel dysfunction symptoms after high fiber intake; therefore, this finding could explain the low consumption of plant foods. Low consumption of fibre induces dysbiosis, which is associated with both endotoxemia and inflammation. Dysbiosis can be reduced by exercise and diet in individuals with SCI. Therefore, to summarize our viewpoint, we developed a Mediterranean diet-based diet and exercise pyramid to integrate nutritional recommendations and exercise guidelines. Nutritional guidelines come from previously suggested recommendations for military veterans with disabilities and individuals with SCI, chronic kidney diseases, chronic pain and irritable bowel syndrome. We also considered the recent exercise guidelines and position stands for adults with SCI to improve muscle strength, flexibility and cardiorespiratory fitness and to obtain cardiometabolic benefits. Finally, dietary advice for Paralympic athletes is suggested.

Development of a novel neurogenic bowel patient reported outcome measure: the Spinal Cord Injury Patient Reported Outcome Measure of Bowel Function & Evacuation (SCI-PROBE)

STUDY DESIGN

Outcome measure item generation and reduction.

OBJECTIVES

To develop a patient reported outcome measure (PROM) addressing the impact of neurogenic bowel dysfunction (NBD) on individuals living with traumatic or nontraumatic spinal cord injury (SCI).

SETTING

Tertiary rehabilitation center in Toronto, Canada.

METHODS

A PROM based on the International Classification of Functioning, Disability and Health (ICF) framework was developed using the following steps: (a) item generation, (b) item refinement through iterative review, (c) completion of items by individuals living with SCI and NBD followed by cognitive interviewing, and (d) further item refinement, item reduction, and construction of the preliminary PROM.

RESULTS

Following initial item generation and iterative review, the investigative team agreed on 55 initial items. Cognitive interviewing, additional revisions, and item reduction yielded an instrument comprised of 35 items; while ensuring at least two items were retained for each of the 16 previously identified challenges of living with NBD following the onset of a SCI. Scoring for the preliminary PROM ranges from 0 to 140.

CONCLUSIONS

A preliminary PROM informed by the ICF for assessing the impact of NBD post-SCI has been devised, which can be used to inform clinicians and decision-makers on optimal ways to treat this serious secondary health complication. Future work will assess the validity and clinimetric properties of the PROM.

Recommendations for evaluation of neurogenic bladder and bowel dysfunction after spinal cord injury and/or disease

Objective: To provide an overview of clinical assessments and diagnostic tools, self-report measures (SRMs) and data sets used in neurogenic bladder and bowel (NBB) dysfunction and recommendations for their use with persons with spinal cord injury /disease (SCI/D).Methods: Experts in SCI/D conducted literature reviews, compiled a list of NBB related assessments and measures, reviewed their psychometric properties, discussed their use in SCI/D and issued recommendations for the National Institutes of Health (NIH), National Institute of Neurological Disorders and Stroke (NINDS) Common Data Elements (CDEs) guidelines.Results: Clinical assessments included 15 objective tests and diagnostic tools for neurogenic bladder and 12 for neurogenic bowel. Following a two-phase evaluation, eight SRMs were selected for final review with the Qualiveen and Short-Form (SF) Qualiveen and the Neurogenic Bowel Dysfunction Score (NBDS) being recommended as supplemental, highly-recommended due to their strong psychometrics and extensive use in SCI/D. Two datasets and other SRM measures were recommended as supplemental.Conclusion: There is no one single measure that can be used to assess NBB dysfunction across all clinical research studies. Clinical and diagnostic tools are here recommended based on specific medical needs of the person with SCI/D. Following the CDE for SCI studies guidelines, we recommend both the SF-Qualiveen for bladder and the NBDS for bowel as relatively short measures with strong psychometrics. Other measures are also recommended. A combination of assessment tools (objective and subjective) to be used jointly across the spectrum of care seems critical to best capture changes related to NBB and develop better treatments.
