Improvement in Neurogenic Bowel and Bladder Dysfunction Following Posterior Decompression Surgery for Cauda Equina Syndrome: A Prospective Cohort Study

Objective: The mechanisms of neurogenic bowel dysfunction (NBD) and neurogenic bladder (NB), which are major consequences of spinal cord injury and occasionally degenerative lumbar disease. The following in patients with cauda equina syndrome who underwent posterior decompression surgery was investigated: (1) the preoperative prevalence of NBD and NB, measured using the Constipation Scoring System (CSS) and International Prostate Symptoms Score (IPSS); (2) the degree and timing of postoperative improvement of NBD and NB.Methods: We administered the CSS and IPSS in 93 patients before surgery and at 1, 3, 6, and 12 months postoperatively. We prospectively examined patient characteristics, Japanese Orthopaedic Association (JOA) score, and postoperative improvements in each score.Results: The prevalence of symptomatic defecation and urinary symptoms at admission were 37 patients (38.1%) and 31 patients (33.3%), respectively. Among the symptomatic patients with defecation problems, 12 patients had improved at 1 month, 13 at 3 months, 14 at 6 months, and 13 at 12 months postoperatively. Among the symptomatic patients with urinary problems, 5 patients improved at 1 month, 11 at 3 months, 6 at 6 months, and 10 at 1 year postoperatively. Comparing patients with improved versus unimproved in CSS, the degree of JOA score improvement was a significant prognosis factor (p < 0.05; odds ratio, 1.05).Conclusion: The prevalence of symptomatic defecation and urinary symptoms in patients with cauda equina syndrome was 38.1% and 33.3%, respectively. Decompression surgery improved symptoms in 30%–50%. These effects were first observed 1 month after the operation and persisted up to 1 year.

Who is managing the bowels? A survey of clinical practice patterns in spina bifida clinics

PURPOSE: Neurogenic bowel dysfunction (NBD) affects 80% of individuals with spina bifida. Performing and disseminating research on NBD to reach the appropriate audience is difficult given the variability among medical specialties managing NBD. This study aimed to identify which medical specialties and types of providers are currently managing NBD in the United States. METHODS: A survey was developed and sent to 75 spina bifida clinics. Surveys queried which specialty was primarily responsible for medical and surgical management of NBD and any others that assist in NBD care. The license and certification level of the providers were collected. Descriptive statistics were performed to describe the results. RESULTS: Response rate was 68%. Urology was the leading specialty primarily responsible for NBD management (39%) followed by rehabilitation medicine and developmental pediatrics (22% and 20%, respectively). Physicians were the primary providers of care followed by nurse practitioners (54% vs 31%). Urology performs 65% of NBD surgeries. CONCLUSION: Multiple specialties and providers are involved in NBD management with variation among clinics. Development of improved NBD care should include a spectrum of specialties and providers. Dissemination of research should be aimed at multiple specialty groups.

Transanal irrigation to treat bowel dysfunction: an update on practice

Transanal irrigation (TAI) has been receiving increasing attention and acceptance in recent years as a treatment option for bowel dysfunction, including chronic constipation, faecal incontinence, neurogenic bowel disorders and lower anterior resection syndrome. TAI involves the instillation of tepid water into the bowel via a rectal catheter or cone to achieve a controlled bowel cleanout. This article addresses the competencies that health professionals require to use TAI. Prior to instigating TAI, these include how to undertake an adequate bowel assessment; understand the risks and complications associated with TAI; and select the equipment most suitable for an individual's bowel symptoms. The professional must also be able to instruct the user in how to safely perform the procedure; discuss contra-indications and cautions; and collect outcome measures, including reasons for discontinuation.

Factors Associated With Neurogenic Bowel Dysfunction Severity in Spinal Cord Injury: A Cross-sectional Study

Background: Neurogenic bowel dysfunction (NBD) caused by spinal cord injury (SCI) is a major life limiting issue for many patients. However, studies detailing the factors contributing to bowel problems are scarce. The aim of this cross-sectional questionnaire-based study was to evaluate the associations between different aspects of bowel problems and characteristics of SCI, such as time since injury (TSI), level of injury (LOI), and the cause of injury. Methods: Two questionnaires (the NBD score questionnaire and the Cleveland clinic constipation system score questionnaire) were administered to complete, traumatic patients with SCI that matched the designated criteria. The total scores and the subscales were then regressed to TSI and LOI, and the distribution patterns of NBD score severity according to LOI and cause of injury were shown in a diagram. Results: Within the subscales of the NBD score, frequency of defecation, digital stimulation or evacuation of the anorectum, and perianal skin problems were all significantly and positively correlated with the TSI, yet the frequency of fecal incontinence was negatively associated with this variable. Moreover, uneasiness, headache, or perspiration during defecation and regular use of drops against constipation were negatively associated with the LOI. In the diagrams, patterns of NBD score severity were similar according to LOI, but visibly differed according to cause. With respect to the CCCS score (Cleveland Clinic Constipation Scoring System), the score itself was shown to be positively associated with TSI. Within the subscales, difficulty, time spent in lavatory, and duration of constipation were positively correlated with TSI. Furthermore, type of assistance was negatively associated with the LOI. Conclusion: Different characteristics of SCI, TSI, LOI, and cause, each are significantly and distinctly associated with different aspects of the bowel problems that patients with SCI face.

Criteria to evaluate neurological lower urinary tract dysfunction in children with Congenital Zika Syndrome: Revised version after the fourth year of use v1

Congenital Zika Syndrome (CZS) has been associated with microcephaly and other central nervous system abnormalities including areas that have been implicated in the control of the lower urinary tract [1] Neurological lower urinary tract dysfunction (NLUTD) is a common condition among patients with CZS and microcephaly [2][1][3][4][5]. But the lack of knowledge that CZS causes NLUTD delays investigation and treatment. This revised version includes changes based on the observations of four-years of experience using our first published protocol [6], the new sequels found in children with CZS, which are cryptorchidism [7] and the neurogenic bowel [5], and related publications [8][9]. This new version includes the vision of the authors, who are from five different institutions in Brazil. They have been working with patients with NLUTD and participate in the development of the new Urological care network for patients with CZS. Our protocol aims to alert health professionals to the relationship between neurological lower urinary tract dysfunction and Congenital Zika Syndrome and to initiate an early investigation to minimize the risks associated with neurological lower urinary tract dysfunction and other genitourinary disorders that may be found in these children. A thorough investigation of these children can reduce the impact of this important sequelae, which is the neurological lower urinary tract dysfunction, reducing comorbidities and consequent impairment of renal function and mitigating the disease burden for patients and families and the Health Systems.

Effects of highly selective sympathectomy on neurogenic bowel dysfunction in spinal cord injury rats

Neurogenic bowel dysfunction, including hyperreflexic and areflexic bowel, is a common complication in patients with spinal cord injury (SCI). We hypothesized that removing part of the colonic sympathetic innervation can alleviate the hyperreflexic bowel, and investigated the effect of sympathectomy on the hyperreflexic bowel of SCI rats. The peri-arterial sympathectomy of the inferior mesenteric artery (PSIMA) was performed in T8 SCI rats. The defecation habits of rats, the water content of fresh faeces, the intestinal transmission function, the defecation pressure of the distal colon, and the down-regulation of Alpha-2 adrenergic receptors in colon secondary to PSIMA were evaluated. The incidence of typical hyperreflexic bowel was 95% in SCI rats. Compared to SCI control rats, PSIMA increased the faecal water content of SCI rats by 5–13% (P < 0.05), the emptying rate of the faeces in colon within 24 h by 14–40% (P < 0.05), and the defecation pressure of colon by 10–11 mmHg (P < 0.05). These effects lasted for at least 12 weeks after PSIMA. Immunofluorescence label showed the secondary down-regulation of Alpha-2 adrenergic receptors after PSIMA occurred mainly in rats’ distal colon. PSIMA mainly removes the sympathetic innervation of the distal colon, and can relieve the hyperreflexic bowel in rats with SCI. The possible mechanism is to reduce the inhibitory effect of sympathetic activity, and enhance the regulatory effect of parasympathetic activity on the colon. This procedure could potentially be used for hyperreflexic bowel in patients with SCI.

Prevalence and predictors of bowel dysfunction in a large multiple sclerosis outpatient population: an Italian multicenter study

Introduction Bowel dysfunction (BD) is reported as a common and disabling symptom in multiple sclerosis (MS) patients. To date, no studies have explored the prevalence of these symptoms in a large multicenter outpatient setting. The aims of the present study are to assess: (i) the prevalence of BD in a large multicenter Italian MS population, and (ii) the correlation between clinico-demographic variables and the severity of BD. Methods Each of the nine participating center screened MS patients prospectively: 1100 subjects were enrolled. All patients underwent the Expanded Disability Status Scale (EDSS) and completed the Neurogenic Bowel Dysfunction score (NBDs). Multivariable linear and logistic regression models were used to assess the association between NBDs and several clinico-demographic variables. Results Fourteen percent of MS patients showed a moderate/severe BD (NBDs > 10); this percentage increased in patients with high disability, ranging from 26 to 32%. Moderate/severe BD was more frequent in MS patients with: progressive phenotypes, higher disability, older age, and longer disease duration. NBDs severity was predicted by female sex, ambulation impairment and bladder symptoms. Conclusion This study confirms the relatively high prevalence of moderate/severe BD in a large, multicenter, unselected, outpatient MS population. BD appears to be mainly associated to female sex and MS-related disability.
