Treatment of fecal incontinence with a comprehensive bowel management program

Economic Impact of Daily Bowel Management Regimens

BACKGROUND

Chronic constipation and fecal incontinence are devastating problems for patients with anorectal malformations, Hirschsprung's disease, idiopathic constipation, and spina bifida/spinal cord injuries. Finding the proper regimen allows these patients to be out of diapers and free of stool accidents. A typical bowel management regimen consists of daily laxatives or enemas; because these products are sold over the counter, insurance companies do not cover them. This study reviews the cost of bowel regimens and analyzes their economic impact on the families we treat.

METHODS

A retrospective review of patients undergoing bowel management between January 2016 and September 2023 was done. The mean annual income of families was calculated using their zip codes.

RESULTS

Upon review, 430 patients met inclusion criteria; 167 were on laxatives, and 263 were using enemas. There was significant variation in the cost of medications based on the distributors they were bought from and the dose of the medication in their regimen. The cost of laxatives ranged from $15.70 to $2938.10 annually. The cost of enemas containing glycerin ranged from $29.20 to $4380.00 annually. In comparison, diapers/incontinence briefs ranged from $131.40 to $4343.50 annually. The median annual income of patients across 41 states ranged from $32,192 to $225,119.

CONCLUSIONS

Our findings emphasize the importance of proper counseling families regarding medication costs in the market, intending to promote long-term treatment adherence. They also serve as a data source to advocate for improved insurance coverage of the medications required to manage these chronic conditions successfully.

Functional Outcome in Patients With Anorectal Malformation With Recto-prostatic or Recto-bulbar Urethral Fistula and Comparison Between Different Surgical Approaches: A Multi-center Study

PURPOSE

To analyze and compare the outcomes in patients with anorectal malformation with rectoprostatic and rectourethral fistula between laparoscopic-assisted anorectoplasty (LAARP) versus posterior sagittal anorectoplasty (PSARP).

METHOD

We performed a retrospective review on all males with anorectal malformation (ARM) with recto-prostatic (ARM-RP) or recto-bulbar urethral fistula (ARM-RB) treated in five tertiary paediatric surgical centres in the past 25 years. Defecative function was assessed using the Krickenbeck classification and Kelly's score. Functional outcomes between patients with LAARP and PSARP were compared.

RESULTS

There were a total of 136 males with ARM-RP and ARM-RB for analysis, among which 73 (53.7%) had ARM-RP and 63 (46.3%) had ARM-RB. The median age of the patients was 9.4 years (range 0.8-24.7 years) and the median age at operation was 0.4 years (0 day-3.1 years). 57 (41.9%) and 79 patients (58.1%) underwent PSARP and LAARP respectively. 34 patients (25%) had VACTERL association. 111 (81.6%) and 103 patients (75.7%) had sacral and spinal cord anomalies respectively. 19 patients (13.9%) eventually required Malone's Antegrade Continence Enema (MACE). For the comparison between PSARP and LAARP, no difference in Kelly scores (4.58 ± 1.63 versus 4.67 ± 1.36) was identified (p = 0.79). Logistic regression for voluntary bowel movement showed that VACTER association (p = 0.02) and fistula location (p = 0.01) were significant prognostic factors, whereas the operation approach (PSARP or LAARP) was not (p = 0.65).

CONCLUSION

VACTERL association and fistula location were significant prognostic factors for voluntary bowel movement, and there appeared to be no significant difference in functional outcome between PSARP and LAARP.

Is the Transrectal Diameter (TRD) Suitable for Assessing Faecal Loads and Monitoring Bowel Management in Children with Hirschsprung Disease-ReKiSo Study: Prospective Study

BACKGROUND

Constipation and outlet obstruction may persist after successful pull-through in Hirschsprung Disease (HD). The radiographic assessment of the faecal load is widely used but exposes the child to radiation. This study aims to evaluate whether the transrectal diameter (TRD) assessed with ultrasound correlates with symptoms of faecal load and whether the TRD normalises when symptoms disappear.

METHOD

Children with HD after pullthrough and functional constipation presenting to our colorectal clinic between 4/23 and 4/24 were assessed for symptoms of constipation, smearing and outlet obstruction, as well as healthy controls. Ultrasound measurement of the TRD was conducted. Bowel management was initiated according to our institutional pathway using Peristeen© irrigation after an orthograde disimpaction regime.

RESULTS

A total of 193 children underwent TRD assessment. Of 60 children with HD, 26 (43.3%) presented with obstructive symptoms, and 34 (56.7%) were asymptomatic. In asymptomatic patients with HD, the mean TRD of 2.26 cm (SD 0.61) was significantly (p < 0.001) lower than in HD with symptoms, with a mean TRD of 3.35 cm (SD 1.03). Individuals without colorectal pathology had a mean TRD of 2.04 cm (SD 0.37), and children with functional constipation and symptoms showed a mean TRD of 4.36 cm (SD 1.32). The mean TRD after symptom resolution was 2.37 cm.

CONCLUSIONS

Children with HD without obstructive symptoms have a TRD < 3 cm, as do controls. The transrectal diameter allows the clinician to sonographically assess the faecal load in children with HD at the bedside without radiation. The TRD is useful for monitoring a bowel management program in children with HD.

Predictors of medical adherence following a bowel management program for youth and young adults with Spina Bifida

PURPOSE

To evaluate individual and community sociodemographic factors that predict bowel regimen adherence in youth and young adults with Spina Bifida (SB) following participation in a bowel management program (BMP).

METHODS

Participants were drawn from clinical cases seen through an International Center for Colorectal and Urogenital Care. Area deprivation index (ADI) scores were extracted from participant addresses and bowel regimen adherence data were collected from the electronic medical record (EMR).

RESULTS

Participants' mean age was 8.06 years old, 51.7% were male, 72.4% white, 37.9% Hispanic, 56.9% government insurance, 89.7% myelomeningocele, 15.5% non-adherent. Average neighborhood disadvantage was 5.19 (SD:2.83, range:1-10). After controlling for variables correlated with adherence (p < .20), every one decile higher neighborhood disadvantage score was associated with a 48% decrease in the odds of being adherent (OR = 0.52, p = .005, 95% CI: - 101.90, - 0.21).

CONCLUSION

Our results suggest that neighborhood disadvantage is a strong predictor of medical adherence following a BMP, more so than other sociodemographic and health-related variables. These results may assist with identifying which individuals may be at higher risk for poor health outcomes due to neighborhood socioeconomic disadvantage and help health care systems intervene proactively.

Medical management of anorectal malformations

BACKGROUND

Anorectal malformations (ARMs) are congenital anomalies of the anorectum and the genitourinary system that result in a broad spectrum of hindgut anomalies. Despite surgical correction patients continue to have late postoperative genitourinary and colorectal dysfunction that have significant impact on quality of life.

AIM

This paper will review the current evidence and discuss the evaluation and management of postoperative patients with ARMs who present with persistent defecation disorder.

METHODS

A literature search was conducted using PubMed/MEDLINE/EMBASE databases applying the following terms: ARMs, imperforate anus, constipation, faecal incontinence, neurogenic bowel, posterior sagittal anorectoplasty.

RESULTS

Patients who present with postoperative defecation disorders require timely diagnostic and surgical evaluation for anatomic abnormalities prior to initiation of bowel management. Goals of management are to avoid constipation in young children, achieve faecal continence in early childhood and facilitate independence in older children and adolescents. Treatment options vary from high dose stimulant laxatives to high-volume retrograde and antegrade enemas that facilitate mechanical colonic emptying.

CONCLUSIONS

Appropriate diagnostic work-up and implementation of treatment can decrease long-term morbidity and improve quality of life in postoperative patients with ARMs who presents with defecation disorders.

Hirschsprung Disease: The Role of the Clinical Nurse Specialist

Hirschsprung disease is a life-long condition that can have a significant impact on both children and their families. This article explores the role of the clinical nurse specialist and the support they can provide from initial diagnosis through the patient's surgical journey and right through to transition into adult services. Through the provision of education, training, signposting of social and psychological support, and linking in with community-based services, the clinical nurse specialist can help the child and family to limit that impact of the disease.

Rectal biopsy: is it really necessary in anorectal malformations?

AIM OF THE STUDY

The coexistence of Hirschsprung's disease (HD) with anorectal malformation (ARM) is rare but many surgeons still ask pathologists to look for ganglia in the terminal rectum or fistula. In this study, we aimed to highlight the rarity of this association and question the necessity of histological evaluation.

METHODS

After obtaining board review approval, rectal specimens of ARM patients who underwent corrective surgery in the last 8 years were re-analyzed by two blinded pathologists for the presence and structure of ganglia. Clinical and radiological data of patients retrieved from center records and correlated with histopathologic findings.

MAIN RESULTS

67 patients with ARM were identified, distal rectal specimen was obtained in 47. The median age at the time of surgery was 11 months (2 days-59 months). A normal pattern of ganglia was present in 51.1% (24/47), 29.7% (14/47) had aganglionosis and 19.1% (9/47) were inconclusive due to insufficient material. None of the aganglionic specimens showed other histological findings of HD. Patients were followed up regularly in the outpatient colorectal clinic for a median of 87 months (42-117 m). Only 6 experienced severe constipation (3 ganglionic, 2 no biopsy, 1 aganglionic), all of whom responded to a bowel management program, and none developed other manifestations of HD (abdominal distension, failure to thrive or enterocolitis) or required additional surgery.

CONCLUSIONS

Our results strongly suggest that the association of ARM and HD is extremely rare and the practice of searching for ganglia in the distal rectum or fistula of ARM patients should be discouraged to avoid potential misdiagnosis and overtreatment.

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.

State of the Art Bowel Management for Pediatric Colorectal Problems: Hirschsprung Disease

After an initial pull-though, patients with Hirschsprung disease (HD) can present with obstructive symptoms, Hirschsprung-associated enterocolitis (HAEC), failure to thrive, or fecal soiling. This current review focuses on algorithms for evaluation and treatment in children with HD as a part of a manuscript series on updates in bowel management. In constipated patients, anatomic causes of obstruction should be excluded. Once anatomy is confirmed to be normal, laxatives, fiber, osmotic laxatives, or mechanical management can be utilized. Botulinum toxin injections are performed in all patients with HD before age five because of the nonrelaxing sphincters that they learn to overcome with increased age. Children with a patulous anus due to iatrogenic damage of the anal sphincters are offered sphincter reconstruction. Hypermotility is managed with antidiarrheals and small-volume enemas. Family education is crucial for the early detection of HAEC and for performing at-home rectal irrigations.

Standardization of radiograph readings during bowel management week

INTRODUCTION

During "bowel management week," abdominal radiographs are used to monitor the amount and location of stool. A radiologist familiar with the treatment plan can provide an improved interpretation. The goal of this paper is to standardize the radiological reports during a bowel management week.

METHODS

We saw 744 patients during bowel management week from May 2016 until March 2023. Diagnosis included: anorectal malformation (397), idiopathic constipation (180), Hirschsprung disease (89), and spina bifida (78). Laxatives were the treatment for 51% of patients, and 49% received enemas. Characteristic radiographs were selected for each treatment group for a proposed reading standardization.

RESULTS

When the stool is visualized, it is crucial to report its location. Having a contrast enema helps with the correct interpretation of the colonic anatomy. It is also essential to always compare the amount of stool with the radiograph from the previous day to determine if there is an increase or decrease in stool. Examples of radiographs are shown to guide the use of the preferred proposed terminology.

CONCLUSION

Providing information regarding which treatment modality the patient is receiving and stating that a patient is on a bowel management week treatment is crucial for the radiologist to provide adequate interpretation. The radiologist must be familiar with the treatment goals and purpose of the daily radiograph.

State of the Art Bowel Management for Pediatric Colorectal Problems: Anorectal Malformations

Up to 79% of patients with anorectal malformations (ARMs) experience constipation and/or soiling after a primary posterior sagittal anoplasty (PSARP) and are referred to a bowel management program. We aim to report the recent updates in evaluating and managing these patients as part of the manuscript series on the current bowel management protocols for patients with colorectal diseases (ARMs, Hirschsprung disease, functional constipation, and spinal anomalies). The unique anatomic features of ARM patients, such as maldeveloped sphincter complex, impaired anal sensation, and associated spine and sacrum anomalies, indicate their bowel management plan. The evaluation includes an examination under anesthesia and a contrast study to exclude anatomic causes of poor bowel function. The potential for bowel control is discussed with the families based on the ARM index calculated from the quality of the spine and sacrum. The bowel management options include laxatives, rectal enemas, transanal irrigations, and antegrade continence enemas. In ARM patients, stool softeners should be avoided as they can worsen soiling.

Evaluation and Management of Postsurgical Patient With Hirschsprung Disease Neurogastroenterology & Motility Committee: Position Paper of North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN)

Children with Hirschsprung disease have postoperative long-term sequelae in defecation that contribute to morbidity and mortality and significantly impact their quality of life. Pediatric patients experience ongoing long-term defecation concerns, which can include fecal incontinence (FI) and postoperative obstructive symptoms, such as constipation and Hirschsprung-associated enterocolitis. The American Pediatric Surgical Association has developed guidelines for management of these postoperative obstructive symptoms and FI. However, the evaluation and management of patients with postoperative defecation problems varies among different pediatric gastroenterology centers. This position paper from the Neurogastroenterology & Motility Committee of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition reviews the current evidence and provides suggestions for the evaluation and management of postoperative patients with Hirschsprung disease who present with persistent defecation problems.

Pediatric Bowel Management Options and Organizational Aspects

A bowel management program (BMP) to treat fecal incontinence and severe constipation is utilized for patients with anorectal malformations, Hirschsprung disease, spinal anomalies, and functional constipation, decreasing the rate of emergency department visits, and hospital admissions. This review is part of a manuscript series and focuses on updates in the use of antegrade flushes for bowel management, as well as organizational aspects, collaborative approach, telemedicine, the importance of family education, and one-year outcomes of the bowel management program. Implementation of a multidisciplinary program involving physicians, nurses, advanced practice providers, coordinators, psychologists, and social workers leads to rapid center growth and enhances surgical referrals. Education of the families is crucial for postoperative outcomes, prevention, and early detection of complications, especially Hirschsprung-associated enterocolitis. Telemedicine can be proposed to patients with a defined anatomy and is associated with high parent satisfaction and decreased patient stress in comparison to in-person visits. The BMP has proved to be effective in all groups of colorectal patients at a 1- and 2-year follow-up with social continence achieved in 70–72% and 78% of patients, respectively, and an improvement in the patients’ quality of life. A transitional care to adult program is essential to maintain the same quality of care, and continuity of care and to achieve desired long-term outcomes as the patient reaches adult age.

Pediatric neurogenic bowel dysfunction: ICCS review document

INTRODUCTION

The International Children's Continence Society (ICCS) aims to improve the quality of life in children with lower urinary tract dysfunction. A substantial portion of children also have problems with bowel dysfunction. There is a lack of evidence-based information on managing neurogenic bowel dysfunction (NBD) in children.

OBJECTIVE/METHODS

The ICCS aimed to provide an up-to-date, selective, non-systematic review of NBD's definitions, assessment, and treatment.

RESULTS

Specific definitions and terminology are defined within the document. Recommendations and considerations for physical assessment, history taking, and diagnostic studies are made. Management updates, both surgical and non-surgical, are provided as well as recommendations for follow-up and monitoring of individuals with NBD.

CONCLUSION

This review of the current literature will help guide NBD management and research to improve NBD care.

Educational and mental health outcomes in school-aged children with anorectal malformations: A case-control cohort study

PURPOSE

Outcome studies for patients with anorectal malformation (ARM) have focused on fecal incontinence and quality of life, but a comparison of educational outcomes between ARM cases and controls has not been reported. The purpose of this study was to assess real-world educational outcomes, neurodevelopmental disorders and mental health disorders in ARM patients and compare to an age-matched control group.

METHODS

We performed a retrospective case-control study of children diagnosed with ARM from 1991 to 2017. We evaluated educational outcomes using an Early Developmental Instrument, Grades 3, 7, and 8 assessments, Grade 9 completion and performance, and high school graduation. Neurodevelopmental and mental health disorders were compared using International Classification of Diseases codes available from a population-based dataset.

RESULTS

A total of 96 ARM cases and 960 controls were identified. Cases were at greater risk of failing to meet expectations on Grades 7 and 8 assessments. After entering high school, ARM patients were at no greater risk than their peers of failing to meet expectations. Cases were more likely to have a developmental or intellectual disability (OR 3.59, p < 0.001), anxiety (OR 1.86, p = 0.023), depression (OR 2.35, p = 0.022) or hyperactivity disorder (OR 2.01, p = 0.036).

CONCLUSIONS

Our study demonstrated that ARM patients may be more likely to perform poorly in junior high school than controls and may be at greater risk of neurodevelopmental and mental health disorders. It is important for pediatric surgeons to anticipate these challenges and endorse psychosocial supports to optimize educational and mental health outcomes.

Significance of searching for ganglia in the terminal rectum/fistula of complex anorectal malformations: Related to defecation function

Background

The need to search for ganglia in the terminal rectum/fistula of complex anorectal malformations (ARMs) remains controversial. This study aims to evaluate the relationship between ganglia absence in the terminal rectum/fistula and defecation function after anoplasty.

Methods

A retrospective review of patients who received anoplasty for treating male imperforate anus with rectobulbar (RB)/rectoprostatic (RP) fistulas at a tertiary pediatric hospital was conducted with registered demographic data, imaging study results, and information on the terminal rectum/fistula specimen (excision extension and pathological findings). According to the pathological findings, patients were divided into Groups 1 (ganglia absence) and 2 (ganglia presence). Furthermore, the postoperative defecation function was evaluated using various rating scale questionnaires. Statistical analysis was performed using SPSS 22.0.

Results

Of the 62 patients, 18 (29.0%) showed ganglia absence in the terminal rectum/fistula. By analyzing the imaging data, spinal anomalies and spinal cord anomalies were found in 30.6% (19/62) and 56.5% (35/62) of patients, respectively. Baseline information was comparable between Groups 1 and 2 (P > 0.05). For defecation function, there were no significant differences in Kelly scores between the two groups (4.0 ± 0.8 vs. 4.4 ± 1.1, P = 0.177), while Krickenbeck (3.7 ± 1.8 vs. 5.2 ± 1.4) and Rintala (13.7 ± 3.6 vs. 16.0 ± 2.7) scores in Group 1 were significantly lower than those in Group 2 (both P < 0.05). The overall incidence of constipation was 50% (31/62), being higher for Group 1 than Group 2 (77.5% vs. 38.6%, P = 0.002). The area under the curve of ganglia absence for predicting constipation was 0.696, with 77.8% sensitivity and 61.4% specificity.

Conclusion

Ganglia absence in the terminal rectum/fistula of male imperforate anus with RB/RP fistulas is associated with constipation after anoplasty, but it has limited predictive value for postoperative constipation. It is necessary to search for ganglia in the terminal rectum/fistula, both intraoperatively and postoperatively.

The success rate of antegrade enemas for the management of idiopathic constipation

PURPOSE

Most patients with idiopathic constipation achieve daily voluntary bowel movements with stimulant laxatives after a "Structured Bowel Management Program" (BMP). A small percentage require rectal enemas. One week in a BMP to find the right enema recipe results in a success rate great than 95%. Once the enema is radiologically and clinically effective, antegrade continent enema procedures (ACE) can afford patients an alternative route of enema administration. This study summarized the outcomes of children with idiopathic constipation who receive antegrade enemas (AE) with or without a prior BMP.

METHODS

This was a single institution, retrospective cohort study of children with idiopathic constipation who underwent ACE procedures indicated by different providers from 2015-2020. We categorized the outcomes with AE after the ACE procedure as: "successful outcome" when the AE produced a daily bowel movement, no involuntary bowel movements, and no more fecal impactions, "unsuccessful outcome" was defined when the patient continued having involuntary bowel movements or fecal impaction requiring cleanouts despite a daily AE, and "unnecessary outcome" was defined when the patient was no longer doing AE, but had daily bowel movements, and no involuntary bowel movements or fecal impactions.

RESULTS

Thirty-eight children with idiopathic constipation had an ACE. The most frequent indication for ACE was a failure of medical treatment. The most common medical treatment was polyethylene glycol. Before ACE, 34 (89%) patients did not have a BMP; 18 patients were on rectal enemas and 16 on laxatives. All four with BMP (100%) had a successful rectal enema. After ACE, 12 (31%) patients had successful antegrade enemas, including the four with previous successful BMP with rectal enemas. Twenty patients (52%) had unsuccessful antegrade enemas, and in 6 (15%), the ACE was unnecessary (Fig. 1).

CONCLUSION

Using antegrade enemas without a previously successful formula for rectal enemas has resulted in a high rate of unsuccessful and unnecessary procedures. BMP for children with idiopathic constipation who needs rectal enemas offers a high possibility to find the proper rectal enema recipe and ensures higher rates of successful AE.

Changes in postoperative quality of life of pediatric total colonic aganglionosis patients: effect of pull-through technique

AIM

To assess mid-/long-term quality of life (QOL) of total colonic aganglionosis (TCA) patients.

METHODS

Modified pre-existing QOL assessment tools for general lifestyle (GL), bowel function (BF), and mental health (MH) were administered to postoperative TCA patients from five institutions, who were at least 7 years old to compare Duhamel (with pouch) and Swenson/Soave (without pouch) techniques between children (Ch 7-12 years old), teenagers (Tn 13-19), and adults (Ad 20 and over). For MH, caregivers were also interviewed, but separately. Maximum scores were 12 for GL/MH and 18 for BF.

RESULTS

There were 32 subjects. GL and BF scores increased significantly from Ch (GL 4.8 ± 2.5, BF: 11.3 ± 4.6) to Tn (GL 7.8 ± 2.6, BF 16.2 ± 3.0); scores for MH did not change significantly. Mean caregiver MH scores were significantly lower than mean subject MH scores for all age groups (subject scores: 10.1, 10.7, 10.7 versus caregiver scores: 6.8, 7.8, 8.1 for Ch, Tn, Ad, respectively). PT technique/presence of a pouch did not influence the incidence of enterocolitis or QOL scores.

CONCLUSION

MH responses showed subjects felt better than caregivers believed. This discrepancy could cause conflict despite steadily improving GL/BF. QOL was unaffected by PT technique/presence of a pouch.

Quality of life outcomes in children after surgery for Hirschsprung disease and anorectal malformations: a systematic review and meta-analysis

Background

No systematic review and meta-analysis to date has examined multiple child and parent-reported social and physical quality of life (QoL) in pediatric populations affected by Hirschsprung's disease (HD) and anorectal malformations (ARM). The objective of this systematic review is to quantitatively summarize the parent-reported and child-reported psychosocial and physical functioning scores of such children.

Methods

Records were sourced from the CENTRAL, EMBASE, and MEDLINE databases. Studies that reported child and parent reported QoL in children with HD and ARM, regardless of surgery intervention, versus children without HD and ARM, were included. The primary outcome was the psychosocial functioning scores, and the secondary outcomes were the presence of postoperative constipation, postoperative obstruction symptoms, fecal incontinence, and enterocolitis. A random effects meta-analysis was used.

Results

Twenty-three studies were included in the systematic review, with 11 studies included in the meta-analysis. Totally, 1678 total pediatric patients with HD and ARM underwent surgery vs 392 healthy controls. Pooled parent-reported standardized mean (SM) scores showed better social functioning after surgery (SM 91.79, 95% CI (80.3 to 103.3), I2=0). The pooled standardized mean difference (SMD) showed evidence for parent-reported incontinence but not for constipation in children with HD and ARM after surgery that had a lower mean QoL score compared with the normal population (SMD -1.24 (-1.79 to -0.69), I2=76% and SMD -0.45, 95% CI (-1.12 to 0.21), I2=75%). The pooled prevalence of child-reported constipation was 22% (95% CI (16% to 28%), I2=0%). The pooled prevalence of parent-reported postoperative obstruction symptoms was 61% (95% CI (41% to 81%), I2=41%).

Conclusion

The results demonstrate better social functioning after surgery, lower QoL scores for incontinence versus controls, and remaining constipation and postoperative obstruction symptoms after surgery in children with HD and ARM.

Impact of Neurodevelopmental Disorders on Bowel Management Outcomes in Children with Functional Constipation

OBJECTIVES

Patients experiencing functional constipation (FC) can participate in structured bowel management programs (BMPs) to manage constipation or fecal incontinence when standard management fails. We sought to evaluate the efficacy of BMPs for children with FC with and without neurodevelopmental disorders.

METHODS

We performed a retrospective review of children with FC who participated in our BMP from 2014 to 2021. Stool/urinary continence, bowel regimen, surgical history, parent-reported outcomes measures (PROMs: Cleveland Clinic Constipation Score, Baylor Continence Scale, Vancouver Symptom Score for Dysfunctional Elimination), and Pediatric Quality of Life Inventory (PedsQL) were assessed pre- and at least 9 months post-BMP.

RESULTS

The cohort included 156 patients with a median age of 9 years and follow-up of 627 days (IQR: 389-808 days). Two sub-cohorts included patients with FC only (69%) and FC plus a neurodevelopmental disorder (31%): 59% attention-deficit/hyperactivity disorder, 33% autism spectrum disorder, and 8% obsessive-compulsive disorder. Both groups had significantly improved follow-up bowel movement frequency and continence (39%-90% neurodevelopmental, 44%-82% FC only, P < 0.001) and urinary continence (65%-90% neurodevelopmental, 69%-91% FC only, P < 0.02). There was a significant improvement in most of the PROMs at follow-up. Both groups experienced a clinically meaningful improvement in overall PedsQL scores (pre- and postBMP difference of >4.5).

CONCLUSIONS

Patients with FC with and without a neurodevelopmental disorder had significant improvement in stool and urinary continence after undergoing a BMP. Further studies are needed to see if this improvement is durable over a longer period of time in this challenging cohort.

Pilot study of an adult bowel management program for fecal incontinence

OBJECTIVE

Bowel management programs are efficacious in pediatric patients with fecal incontinence or intractable constipation unresponsive to standard treatment. No studies have been done examining outcomes in adults. The objective of this study was to assess continence and quality of life outcomes in adults who have underwent bowel management program.

METHODS

A retrospective review of patients 16 or older at the time they underwent a bowel management program for fecal incontinence or constipation was performed. Data collected included intake and follow-up stool and urinary continence, patient-reported outcomes measures (Cleveland Clinic Constipation Score, Baylor Continence Scale, Vancouver Symptom Score for Dysfunctional Elimination), and an age-adjusted health-related quality of life measure.

RESULTS

The cohort included 38 patients with a median age of 19 years (range: 16-55) when they underwent our program. 50% of patients were female and the majority (33, 87%) were White. The most common diagnosis was anorectal malformation (16, 42%) followed by functional constipation (10, 27%). Stool continence rates improved after undergoing the program (52.7% prior to 87.6% at follow-up, p<0.01). There was significant improvement in the Baylor Continence Scale, Cleveland Clinic Constipation Score, and PedsQL (p<0.05).

CONCLUSIONS

Adult patients who underwent a bowel management program for severe fecal incontinence or constipation show significant improvement in stool continence rates, patient-reported outcomes measures, and quality of life. A bowel management program (in-person or via telemedicine) is a feasible treatment strategy for adult patients who fail standard management of fecal incontinence or constipation and should be offered when appropriate.

Evaluation and treatment of the post pull-through Hirschsprung patient who is not doing well; Update for 2022

After operative intervention for Hirschsprung disease (HD) a child should thrive, be fecally continent, and avoid recurrent episodes of abdominal distention and enterocolitis. This is unfortunately not the case for a significant number of patients who struggle following their pull-through procedure. Many clinicians are puzzled by these outcomes as they can occur in patients who they believe have had a technically satisfactory described operation. This review presents an organized approach to the evaluation and treatment of the post HD pull-through patient who is not doing well. Patients with HD who have problems after their initial operation can have: (1) fecal incontinence, (2) obstructive symptoms, and (3) recurrent episodes of enterocolitis (a more severe subset of obstructive symptoms). After employing a systematic diagnostic approach, successful treatments can be implemented in almost every case. Patients may need medical management (behavioral interventions, dietary changes, laxatives, or mechanical emptying of the colon), a reoperation when a specific anatomic or pathologic cause is identified, or botulinum toxin when non-relaxing sphincters are the cause of the obstructive symptoms or recurrent enterocolitis.

The importance of dedicated colorectal team participation in the management of spina bifida and spinal cord injury patients

PURPOSE

In September 2020, the colorectal team of the International Center for Colorectal and Urogenital Care joined the spina bifida and spinal cord injury multidisciplinary clinic at Children's Hospital Colorado. Many important lessons were learned.

METHODS

A retrospective review of patients seen in the spina bifida and spinal cord injury multidisciplinary clinic from September 2020 to May 2021 was conducted. Data collected included demographics, diagnosis, pre or post-natal repair for those with myelomeningocele, whether the patient was previously seen by the colorectal team, wheelchair usage, voluntary bowel control vs. fecal incontinence, urinary control vs. clean intermittent catheterization, characteristics of contrast enema, and our proposed intervention.

RESULTS

Overall, 189 children were seen during the study period, ranging from 3 months to 20 years of age (average = 9.5 years). One hundred and two were males and 87 were females. Diagnosis included myelomeningocele (n = 153), spinal cord injury (n = 18), transverse myelitis (n = 7), sacral agenesis (n = 5), diastematomyelia (n = 2), spinal stenosis (n = 2), and tethered cord with lipoma (n = 2). Fifteen patients with myelomeningocele were repaired in-utero. One hundred and sixty patients were new to the colorectal team. Eighty-one patients were wheelchair users. One hundred and twenty-three patients suffered from fecal incontinence and needed enemas to be artificially clean for stool and thirty-eight patients had voluntary bowel movements and were clean with laxatives, suppository, or rectal stimulations. Twenty-eight patients were younger than three years of age and still in diapers. Despite a non-dilated colon on contrast enema, this population has a hypomotile colon. One hundred and twenty-eight patients required clean intermittent catheterization.

CONCLUSION

Joining the spina bifida and spinal cord injury multidisciplinary clinic allowed us to better serve this population and gave us enormous satisfaction to contribute to improve the quality of life of the patients and their parents.

Outcomes of a telemedicine bowel management program during COVID-19

PURPOSE

Due to the COVID-19 pandemic, we transitioned from an in-person bowel management program (BMP) to a telemedicine BMP. The telemedicine BMP consisted of video and/or phone call visits (remote) or a single initial in-person visit followed by remote visits (hybrid). We hypothesized that patient/family satisfaction of a telemedicine BMP would be comparable to an in-person BMP and that there would be improvement in quality of life and functional outcomes after the telemedicine BMP.

METHODS

After IRB approval, demographic and outcomes data were obtained for patients who underwent the telemedicine BMP from May-October 2020. Outcomes included a parent/patient satisfaction survey, Pediatric Quality of Life Inventory (PedsQL), and parent/patient-reported outcome measures (Vancouver, Baylor, and Cleveland scores) at baseline, 1 and 3 month follow-up. Variables were compared using Chi-square or Wilcoxon-Mann-Whitney tests and a generalized mixed model was used to evaluate outcomes scores at follow-up compared to baseline.

RESULTS

Sixty-seven patients were included in our analysis with an average age of 8.6 years (SD: 3.9). Patients had the following diagnoses anorectal malformation (52.2%), Hirschsprung's disease (20.9%), functional constipation (19.4%), myelomeningocele (6.0%), and spinal injury (1.5%). Forty-eight patients (72%) underwent the remote BMP and 19 (28%) underwent the hybrid BMP. Sixty-two percent of parents completed the satisfaction survey, with a median score of 5 (very satisfied) for all questions. Over 75% of parents said they would prefer a telemedicine program over an in-person program. There was significant improvement in the Baylor and Vancouver scores after the BMP (p < 0.01), but no difference in the PedsQL or Cleveland scores (p > 0.05). There was a significant improvement in stool continence after the BMP (p < 0.01).

CONCLUSION

A telemedicine BMP can be an acceptable alternative to a traditional in-person program. There was high parental/patient satisfaction and significant improvement in outcomes. Further research is needed to assess long-term outcomes.

Considering the value of online support groups for colorectal conditions: perspectives from caregivers and adult patients

PURPOSE

To evaluate the benefits of participating in an online support group for caregivers of children with a colorectal condition or adult patients with a similar condition.

METHODS

An electronic survey was administered to members of an international online support group (18 items for caregivers; 15 for patients). Items included demographics, medical diagnosis, potential benefits, and overall experiences in the group. Quantitative results were summarized as descriptive trends, while qualitative responses were summarized thematically.

RESULTS

Respondents (102 caregivers, 6 patients) were primarily female, 35-44 years old, Caucasian, and resided in the United States. Most respondents learned about the support group from medical providers or online search. Cited benefits included learning information, gaining support, forming connections through shared experience, and utilizing a unique resource. Being a member of the group was helpful to respondents, improved their mental health and access to health information, and they would recommend the group to others.

CONCLUSION

Participation in online support groups offers educational and emotional benefits to patients/caregivers which complements the medical support from their colorectal teams. Thus, colorectal providers need to be aware of the availability and potential benefits of these groups, and encourage their patients/caregivers to be actively involved.

Advanced Management Protocol of Transanal Irrigation in Order to Improve the Outcome of Pediatric Patients with Fecal Incontinence

Background: Transanal irrigation (TAI) is employed for children with fecal incontinence, but it can present several problems which require a study of their outcomes among different pathologies and without a tailored work up. The aim of our study was to evaluate the effectiveness of an advanced protocol in order to tailor TAI, prevent complications, and evaluate outcomes. Methods: We included 70 patients (14 anorectal malformation, 12 Hirschsprung’s disease, 24 neurological impairment, 20 functional incontinence) submitted to a comprehensive protocol with Peristeen^®: fecal score, volumetric enema, rectal ultrasound, anorectal 3D manometry, and diary for testing and parameter adjustment. Results: Among the patients, 62.9% needed adaptations to the parameters, mainly volume of irrigated water and number of puffs of balloon. These adaptations were positively correlated with pre-treatment manometric and enema data. In each group, the improvement of score was statistically significant in all cases (p 0.000); the main factor influencing the efficacy was the rate of sphincter anomalies. The ARM group had slower improvement than other groups, whereas functional patients had the best response. Conclusions: Our results showed that TAI should not be standardized for all patients, because each one has different peculiarities; evaluation of patients before TAI with rectal ultrasound, enema, and manometry allowed us to tailor the treatment, highlighting different outcomes among various pathologies, thus improving the efficacy.

Lower Gastrointestinal Functional and Motility Disorders in Children

Functional and motility gastrointestinal disorders are the most common complaints to the pediatric gastroenterologist. Disorders affecting the small intestine carry a significant morbidity and mortality due to the severe limitation of therapeutic interventions available and the complications associated with such interventions. Congenital colorectal disorders are rare but also carry significant morbidity and poor quality of life plus the social stigma associated with its complications. In this review, we summarize the clinical presentation, diagnostic evaluations, and the therapeutic interventions available for the most common and severe gastrointestinal functional and motility disorders of the small bowel, colon, and anorectum.

Evaluation and Management of Persistent Problems After Surgery for Hirschsprung Disease in a Child

PURPOSE OF REVIEW

Ideally, after operative intervention, a child born with Hirschsprung disease (HD) should thrive, achieve fecal continence, and avoid recurrent episodes of abdominal distention and enterocolitis. However, a significant number of patients continue to struggle following their pull-through procedure. The purpose of this review is to present an organized and practical approach to the evaluation and management of the symptomatic patient post pull-through operation for HD.

RECENT FINDINGS

Children diagnosed with HD who are not doing well after their initial operation can be categorized in three distinct groups: (1) those that have fecal incontinence, (2) those with obstructive symptoms, and (3) those with recurrent episodes of enterocolitis. It is important to have a systematic diagnostic approach for these patients based on a comprehensive protocol. All three of these patient groups can be treated with a combination of either medical management, reoperation when a specific anatomic or pathologic etiology is identified, or botulinum toxin for non-relaxing sphincters contributing to the obstructive symptoms or recurrent enterocolitis. For patients not doing well after their initial pull-through, a systematic workup should be employed to determine the etiology. Once identified, a multidisciplinary and organized approach to management of the symptomatic patients can alleviate most post pull-through symptoms.

Commentary on "One-year impact of a bowel management program in treating fecal incontinence in patients with Anorectal Malformations"

This is a commentary on the manuscript entitled "One-Year Impact of a Bowel Management Program in Treating Fecal Incontinence in Patients with Anorectal Malformations" by Richard Wood and colleagues.

One-year impact of a bowel management program in treating fecal incontinence in patients with anorectal malformations

BACKGROUND

Many patients with anorectal malformations (ARM) need a bowel management program (BMP) to manage lifelong problems of fecal incontinence or severe constipation. We aimed to evaluate the sustainability of the results in such a program.

METHODS

A single-institution retrospective review was performed in children with ARM who attended our BMP (2015-2019). Standardized definitions and validated tools were used to assess fecal continence (Baylor Continence Scale), constipation (Cleveland Constipation Scoring System), urinary symptoms (Vancouver Symptoms Score), and the Pediatric Quality of Life (PedsQL) and health-related quality of life (HRQOL) at the start of BMP and 1-year after completion of the program.

RESULTS

222 patients with ARM at a median age of 6.7 (IQR, 4.9-10.1) years were identified. All (100%) soiled at intake with 149 (67.1%) patients being treated with rectal or antegrade enemas and 73 (32.9%) with oral laxatives. At 1 year 150 (70.4%) were clean, 72.7% were on enemas and 27.3% were on laxatives (p = 0.08). 109 out of 148 (73.6%) patients were clean on enemas. A further 41 out of 66 (62.1%) patients were continent on laxatives with voluntary bowel movements and clean. In the group that was clean, there was improvement in Baylor Continence Scale (25 vs. 13.0, p < 0.000000002), Vancouver (11 vs. 6, p = 0.0110) scores, and clinically relevant improvement in the total PedsQL HRQL (78-85) and the PedsQL HRQL physical function (86-92) and psychosocial domain (77-82). There was no improvement in Cleveland (10 vs. 9, p = 0.31) score.

CONCLUSION

An intensive BMP offers significant benefits in the treatment of fecal incontinence in ARM. It appears to also improve urinary incontinence and urinary voiding as well as the patient's quality of life. These changes are sustainable over at least one year.

Prospective quality of life outcomes in pediatric fecal incontinence following bowel management

BACKGROUND

Severe fecal incontinence (FI) is common in patients both with and without anorectal malformations. Whether a formal bowel management program (BMP) has significant effects on FI, psychosocial development of the child, and caregiver stress is poorly understood. We hypothesize that BMP participation results in long-term clinical and quality of life (QOL) improvements for patients and caregivers.

METHODS

Using a prospective cohort study over three years, 342 children (age 3-12 years) and caregivers were followed for one year after attending a week-long BMP, during which a regimen was tailored to promote daily stool evacuation.FI QOL was measured with the validated Cincinnati Fecal Incontinence Scale (CINCY-FIS), evaluating multiple subscales, including parental stress. Scores were obtained at multiple timepoints following BMP (baseline, 2 weeks, 3 months, 1 year).

RESULTS

Within 2 weeks, BMP participation significantly improved FI with increased frequency of daily daytime voluntary bowel movements (20%-70%, p < 0.001) and decreased daily daytime and nighttimeinvoluntary bowel movements (60%-20%, p < 0.001; 30%-10%, p < 0.05). Marked improvements in CINCY-FIS were observed across multiple QOL subscales, with the greatest in parental stress, and sustained through one year.

CONCLUSIONS

BMP results in significant and sustained improvement in FI and QOL for patients and caregivers.

Outcomes according to channel type for continent catheterizable channels in patients undergoing simultaneous urinary and fecal reconstruction

INTRODUCTION

When creating a continent catheterizable channel (CCC) the choice of bowel segment used as the conduit should be tempered with the morbidity associated with it. The split-appendix technique allows the creation of both a urinary and fecal CCC without the need for a bowel anastomosis. However, there is concern that by splitting the appendix there is compromise to its blood supply and may affect outcomes. We aim to compare what affect the bowel segment used for urinary and fecal CCCs has on perioperative and long-term outcomes in patients undergoing simultaneous urinary and fecal reconstruction.

METHODS

A retrospective review was performed analyzing all patients that underwent simultaneous continent catheterizable urinary and fecal CCC between the years 2010-2016. Patient demographics, channel characteristics, perioperative complications and clinical success rate were analyzed.

RESULTS

A total of 106 patients were identified that had simultaneous fecal and urinary CCC created at time of reconstruction. For urinary CCC, there were 64 patients (60.4%) that underwent a split-appendix technique, 27 patients (25.4%) underwent a Monti, and 15 patients (14.2%) had the appendix used only for the urinary channel. Those patients undergoing a split-appendix technique had median operative time of 447 min compared to 619 min when a Monti channel was created. The median length of hospital stay was 9 days for the split-appendix technique compared to 12 and 13 day median hospital stay when the appendix was used only for the urinary channel or a Monti was created, respectively. There was no difference seen in revision free survival of the channel following surgery of any of the channels with median follow-up of 44.5 months. However, there were more subfascial revisions of urinary CCC in those that underwent a Monti (5 patients, 18.5%) compared to other bowel segments (0 patients).

CONCLUSIONS

Utilizing a split-appendix approach for creation of urinary and fecal CCCs does not affect 30-day complications or long-term revision rates compared to other established techniques. This technique minimizes the potential surgical morbidity of a bowel anastomosis and provide shorter operative times, when feasible, at time of simultaneous creation of fecal and urinary CCC.

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.

Analysis of patients' and caregivers' psychosocial functioning in colorectal conditions: comparison of diagnosis, gender, and developmental functioning

PURPOSE

To evaluate the psychosocial functioning of caregivers and patients with anorectal malformation (ARM), Hirschsprung disease (HD), spinal conditions, and idiopathic constipation (IC) during the beginning of participation in bowel management program (BMP).

METHODS

In this retrospective study, Parent Stress Scale (PSS, parent-report) and Strengths and Difficulties Questionnaire (SDQ, parent-proxy; SDQ-S, self-report for 11 years and older) were used to evaluate parental stress levels and behavioral functioning, respectively. Descriptive and comparative statistical approaches were applied to summarize the data and to determine differences in scores between diagnoses, gender, and developmental functioning.

RESULTS

Two hundred patients and caregivers participated in BMP during the study period. PSS scores were significantly higher for caregivers of patients with IC than ARM. Statistical differences in SDQ were found for patients with IC versus those with ARM, male versus female patients, and patients with developmental delays versus those without delays. No significant differences were found in SDQ-S scores between these groups.

CONCLUSION

Key findings suggest that level of parental stress and behavioral concerns were significantly influenced by diagnoses, and partly by gender and presence of developmental delay. Thus, psychosocial support may need to be tailored based on these findings to provide optimum quality of care for patients and families.

Enema-Induced spastic left colon syndrome: An unintended consequence of chronic enema use

BACKGROUND/PURPOSE

Enemas have become a common practice for treating fecal incontinence and severe constipation. Several patients receiving enemas complained of severe, colicky, abdominal pain during enema administration and complained that the duration for fluid to pass was progressively increasing. Contrast studies showed a startling picture of severe right colon dilatation and a spastic, narrow, left colon. An investigation was started to seek the origin and possible management of this condition.

METHODS

Medical and radiologic records were reviewed retrospectively, with emphasis on the type and ingredients of enemas used, the duration the patients had been receiving enemas, and their original diagnosis. A literature review was done on previous reports of this condition and publications related to long-term use of enemas.

RESULTS

This series included 22 patients (average age, 19.6 years; range, 8-54) with fecal incontinence due to anorectal malformations (10 cases), myelomeningocele (5), cloaca (2), severe colonic dysmotility (2), Hirschsprung's disease (2), and sacrococcygeal teratoma (1). The average duration of enema use was 13.7 years (range, 4-45). The composition of the enemas included saline/glycerin (six cases), only saline solution (five), saline/glycerin/soap (four), plain water (three), and one case each of molasses/milk, saline/glycerin/soap/phosphate, saline/phosphate, and only phosphate. The enemas were performed in an antegrade fashion in 21 cases and rectally in 1. All patients had a dilated right colon and a narrow, spastic, left, transverse, and descending colon. Four patients underwent colonoscopy, colonic manometry, and mucosal biopsies, which did not help in explaining the etiology of the problem. In the literature, 43 reports mentioned a "long-term follow-up" for the administration of enemas, but we could not find a description of symptoms, such as in our cases.

CONCLUSIONS

An intriguing and, to our knowledge, previously unreported complication of chronic enema use is presented. We call attention to an overly concerning complication and report our findings in the hope that they will aid and stimulate more investigations into this condition. Several hypotheses to explain the cause are presented, as well as potential treatment options.

Multi-institutional review of bowel management strategies in children with anorectal malformations

BACKGROUND/RATIONALE

To describe current bowel management program (BMP) strategies in anorectal malformation (ARM) patients based on patient-level predictors using data from a multi-institutional consortium.

MATERIALS/METHODS

Patient bowel function and BMP were reviewed from Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) data. The PCPLC is comprised of multidisciplinary specialists researching colorectal and pelvic disorders. Seven US institutions submitted de-identified clinical data on ARM patients into a centralized patient registry.

RESULTS

The primary ARM of 624 patients was categorized into Mild (45.2%), Moderate (40.4%) or Complex (14.2%) anomaly classifications. Patient-specific BMP were examined based on age and on the presence of spinal cord/sacral anomalies. 418 (67%) enrolled patients were prescribed BMP (<5 yo 56.4%; ≥5-<12 yo 86.7%; ≥12 81.5%). Constipation was the primary chief complaint (80.2%). Forty percent of patients on a BMP were toilet trained and approximately one-half (48.5%) reported daytime stool accidents. Secondary surgical interventions for antegrade continence enemas (ACE) were examined; 14.5% of patients employed ACE strategies and utilization increased with age and varied based on anatomic anomalies.

CONCLUSIONS

This is the first report on BMP strategies for patients with ARM from the Pediatric Colorectal and Pelvic Learning Consortium. Individual patient characteristics are explored for their impact on bowel management strategy utilization.

Assessing the benefit of reoperations in patients who suffer from fecal incontinence after repair of their anorectal malformation

BACKGROUND AND AIM

Patients with a previously repaired anorectal malformation (ARM) can suffer from complications which lead to incontinence. Reoperation can improve the anatomic result, but its impact on functional outcomes is unclear.

METHODS

We performed a retrospective cohort study of patients with a previously repaired ARM who underwent redo PSARP at our Center and compared results at initial assessment and 12 months after redo.

RESULTS

One hundred fifty-three patients underwent a redo PSARP for anoplasty mislocation (n=93, 61%), stricture (n=55, 36%), remnant of the original fistula (n=28, 18%), or rectal prolapse (n=11, 7%). Post-redo complications included stricture (n=33, 22%) and dehiscence (n=5, 3%). At 1-year post-redo, 75/153 (49%) are on laxatives only, of whom 57 (76%) are continent of stool. Of the remaining 78 (51%) patients, 61 (78%) are clean (≤1 accident per week) on enemas. Interestingly, 16/79 (20%) of patients with expected poor continence potential were continent of stool on laxatives. Overall, 118/153 (77%) are clean after their redo. Quality of life (76.7 vs. 83.8, p=0.05) and Baylor continence (29.2 vs. 17.7, p=<0.0001) scores improved.

CONCLUSION

Patients with fecal incontinence after an ARM repair can, with a reoperation, have their anatomy corrected which can restore continence for many, and improve their quality of life.

Should the search for ganglia in the distal rectal fistula in patients with anorectal malformation be abandoned?

PURPOSE

Occurrence of Hirschsprung's disease in anorectal malformation (ARM) patients is rare, but many surgeons still ask to pathologists to search for ganglia in the terminal rectum/fistula; the histological procedure is time and money consuming and the results confounding. A consecutive series of ARM patients, in which the presence of ganglia in terminal rectum was revised, is herein presented.

MATERIALS AND METHODS

Rectal specimens of ARM patients who underwent corrective surgery in the last 6 years were retrieved. The histological protocol included H&E staining and calretinin immunohistochemistry. Each specimen is processed until all material is examined if no ganglia are retrieved after the first twelve sections.

RESULTS

Forty cases were examined. Eight patients were younger than 1 month of age at operation. The mean length of the specimen was 1.5cm (range: 1-3 cm). Upon clinical request, ganglia were searched in 15/40 cases (37.5%) and resulted absent in 10/15 (66.5%). All patients have been followed and none developed signs or symptoms suggestive for Hirschsprung.

CONCLUSIONS

The practice to search for ganglia in the terminal rectum/fistula in ARM patients should be abandoned, as incidence of associated colorectal diseases is rare. Moreover, the procedure is expensive both in terms of laboratory's reagents and working time of expert pathologists and technicians.

Quality of life in children with pseudoincontinence after implementing a bowel management program in Egypt

AIM OF THE STUDY

The aim of this study was to evaluate the impact of implementing a Bowel Management Program (BMP) on the quality of life (QOL) in children with pseudoincontinence.

METHOD

Children aged 2.5-13 years with pseudoincontinence were included. Evaluations were performed before and after BMP implementation. Perceptions from parents about QOL were assessed by a QOL questionnaire, and the severity of fecal incontinence (FI) was assessed using the fecal incontinence index (FII) of the Wexner scale.

RESULTS

115 children (mean age of 7.54 ± 2.48) were studied over a 3-12 month period (mean duration 4.36 months). QOL improved from 2.45 ± 1.57 to 14.36 ± 1.37, P˂0.05. There was a significant improvement of the FII: 18.65 ± 1.25 versus 0.13 ± 0.39, P˂ 0.05. There was a significant inverse correlation between the final scores of QOL (14.36 ± 1.37) and FII (0.13 ± 0.39) after implementation of the BMP (r = -0.53; P ˂ 0.05).

CONCLUSION

This is the largest case series examining QOL in pseudoincontinent children. It demonstrates that BMP significantly improves the QOL of these children in the short and midterm. In addition, it is feasible to apply the FII in assessing incontinence in children. To our knowledge, this is the first study of its kind in our region.

How much do we know about constipation after surgery for anorectal malformation?

BACKGROUND

To evaluate the occurrence of constipation after anorectal malformations (ARM) repair and the results of laxative treatment.

METHODS

Between August 2012 and July 2017, the clinical data of patients with ARMs was prospectively collected. The patients were divided into two groups, good types and poor types. Good types included rectoperineal, rectovestibular, rectourethral bulbar, and no fistula. Risk factors were defined as spinal cord anomalies, sacral ratio <0.4, or cognitive impairment. Success was defined as that laxative could be tapered.

RESULTS

Eighty-four patients were enrolled with mean age of 6.3 ± 7.8 (0.6-59.9) years. The mean age of onset of constipation was 12.8 ± 8.3 months and the mean interval was 5.9 ± 5.1 months after reconstructions. The interval was not significantly different between patients with good types and poor types. In 23 patients with severe constipation being treated for >6 months, 14 of 18 (77.8%) patients with good types were classified as success, whereas only 1 of 5 (20%) patients with poor types was (p = 0.02). In patients with good types, 9 of 9 (100%) patients with no risk factors were successful; however, only 5 out of 9 (55.6%) patients with risk factors were successful (p = 0.02).

CONCLUSION

Constipation occurs shortly after operations. Patients with good types and no risk factors are susceptible to weaning laxatives.

Middle-term bowel function and quality of life in low-type anorectal malformation

BACKGROUND

Low-type anorectal malformations (ARMs) are considered benign; however, in China, data regarding such conditions are limited. Thus, this study aimed to assess the middle-term bowel functions and quality of life (QOL) among children with low-type ARM.

METHODS

Children > 3 years of age who underwent treatment for low-type ARM (vestibular fistula [VF] and perineal fistula [PF]) during 2013 and healthy children were included. The children were interviewed during their outpatient visits. The primary outcome measures were bowel function, as assessed using the Baylor Continence Scale (BCS), and QOL, as measured using the Pediatric Quality of Life Inventory (PedsQL 4.0).

RESULTS

A total of 82 patients responded; mean patient age was 6.8 (range, 3-12) years. Mean BCS score in the control group (7.94 ± 4.74) was significantly lower than that in the VF (18.69 ± 11.11, P < 0.001) and PF (15.47 ± 6.50, P < 0.001) groups. However, there were no differences in PedsQL 4.0 scores among the groups. The patients scored the lowest for emotional function and the highest for physical function. Nearly all measurements of QOL significantly decreased with increased BCS score.

CONCLUSIONS

Children with low-type ARM can achieve good bowel control and QOL. However, although ARMs are benign, several children with this condition suffer from anal function problems that affect QOL. Redo operations, mislocated anus, and incorrect constipation treatment are the iatrogenic causes of fecal incontinence.

Development of a Patient-reported Experience and Outcome Measures in Pediatric Patients Undergoing Bowel Management for Constipation and Fecal Incontinence

AIMS AND OBJECTIVES

The aim of this review is develop a reliable and valid questionnaire that assesses patient-reported experience measures (PREMs) and patient-reported outcome measures (PROMs) of caregivers, families, and patients with severe constipation and fecal incontinence who failed conservative treatments and require a formal bowel management program (BMP).

METHODS

A 5-step iterative process was utilized to ensure the reliability and validity of the final instrument. Parents or guardians of patients undergoing our week-long BMP were first asked 20 open-ended questions aimed at understanding the challenges in managing their child's condition. Responses were transformed into an initial 41-item survey constituted of 2 constructs relating to PREMs (24 items) and PROMs (17 items). Survey items were then administered to 359 parents and guardians undergoing BMP. Cognitive interviews were performed with 20 families to assess face validity and to further refine the survey. Instrument readability and reliability was assessed by Flesch-Kincaid and Crohnbach α analyses. Items that weakly correlated were deleted to yield a final instrument that was both valid and reliable.

RESULTS

A 33-statement survey was developed that encompasses important physical and emotional health concerns, quality of life, treatment success, financial considerations, schooling, parental employment, and social concerns. The final instrument, the Patient-Reported Experience and Outcome Measure in a Bowel Management Program (PREOM-BMP), is divided into 2 separate constructs that assess important patient-reported experience (22 items) and outcome (11 items) measures. Reliability analyses on the final instrument yielded a Crohnbach α of 0.925.

CONCLUSIONS

The PREOM-BMP offers physicians and nursing professionals a brief and valid tool to measure the impact of a bowel management program on both the child and the family unit.

Can fecal continence be predicted in patients born with anorectal malformations?

PURPOSE

The purpose of this study was to identify factors associated with attaining fecal continence in children with anorectal malformations (ARM).

METHODS

We performed a multi-institutional cohort study of children born with ARM in 2007-2011 who had spinal and sacral imaging. Questions from the Baylor Social Continence Scale were used to assess fecal continence at the age of ≥4 years. Factors present at birth that predicted continence were identified using multivariable logistic regression.

RESULTS

Among 144 ARM patients with a median age of 7 years (IQR 6-8), 58 (40%) were continent. The rate of fecal continence varied by ARM subtype (p = 0.002) with the highest rate of continence in patients with perineal fistula (60%). Spinal anomalies and the lateral sacral ratio were not associated with continence. On multivariable analysis, patients with less severe ARM subtypes (perineal fistula, recto-bulbar fistula, recto-vestibular fistula, no fistula, rectal stenosis) were more likely to be continent (OR = 7.4, p = 0.001).

CONCLUSION

Type of ARM was the only factor that predicted fecal continence in children with ARM. The high degree of incontinence, even in the least severe subtypes, highlights that predicting fecal continence is difficult at birth and supports the need for long-term follow-up and bowel management programs for children with ARM.

Error traps and culture of safety in anorectal malformations

INTRODUCTION

Attempting to decrease iatrogenic injuries and preventable harm, safety initiatives have become a priority in surgery. For adult hepatobiliary surgery, it has become common to study and consider "error traps" or common pitfalls that exist for laparoscopic cholecystectomy.^1-4 Extending this work to children, we have attempted to apply some of these initiatives by identifying error traps common to the care of patients born with anorectal malformations (ARM).

METHODS

Five error traps were identified based on a retrospective analysis of operative records and radiographic studies from 398 re operative ARM cases performed by the authors. Once identified, the authors constructed a specific safety plan for each trap to promote a culture that will hopefully prevent ARM iatrogenic injuries.

RESULTS

The identified error traps are: 1) creation of a colostomy too distal in the sigmoid colon, 2) inaccurate distal colostogram and definition of the patient's preoperative anatomy 3) absence of a Foley catheter during the repair of an ARM in males and the hazards of separating the anterior rectal wall from the genito-urinary (GU) tract 4) mismanagement of a post-operative anal stricture following an ARM reconstructive procedure 5) limited or unstructured follow up of these patients. For each of the five traps the authors present suggestions for their avoidance.

CONCLUSION

The repair on an anorectal malformation is an elective procedure and while not completely avoidable, there should be little tolerance for iatrogenic injury and preventable harm. A culture of safety should be followed, beginning with a recognition of the common error traps associated with ARM procedures.

Transition of care: a growing concern in adult patients born with colorectal anomalies

PURPOSE

Traditionally, the care of children and adults has been arbitrarily separated into pediatric and adult medicine and surgery. Despite progress in pediatric surgical techniques, patients born with congenital anomalies still suffer from significant functional sequelae, which persist into adulthood. We aim to describe some of the most common problems experienced by adult patients with congenital colorectal malformations.

METHODS

Following IRB approval, we performed a retrospective database review of all adult patients who were treated by our group from 1983 until 2017.

RESULTS

We identified 88 cases. 51 patients had ARM, 18 cloacas, 9 presacral masses, 3 HD, 2 spina bifida and 5 with other diagnoses (3 vaginal anomalies, 1 cloacal exstrophy, 1 obstructed seminal vesical). The specific problems addressed were: complications from previous operations (41), rectal prolapse (25), fecal incontinence (11), gynecologic concerns (12), urologic concerns (6), and recurrent recto urogenital fistula (3). We performed 83 surgical interventions, including 13 rectal prolapse repair, 13 continent appendicostomies, 44 PSARP or redo PSARP, 11 resections of presacral masses, 11 vaginoplasties, 2 examinations under anesthesia, and 2 Mitrofanoff procedures. Five patients were treated medically (bowel management program, obstetric, urologic evaluation).

CONCLUSION

There is a growing need to better prepare adult providers to assume the care of patients born with congenital colorectal disease as these patients transition to adulthood. A collaboration between specialized pediatric referral centers with adult colorectal surgeons, urologists and gynecologists is a potential pathway for the adequate transition of care.

Short versus mid-long-term outcome of transanal irrigation in children with spina bifida and anorectal malformations

PURPOSE

We assessed short- and mid-long-term clinical efficacy of transanal irrigation (TAI) and its effect on the quality of life of children with spina bifida (SB) and anorectal malformations (ARM).

METHODS

Seventy-four pediatric patients (age 6-17 years) with SB and ARM with neurogenic bowel dysfunction were enrolled for a prospective and multicentric study. Patients were evaluated before the beginning of TAI (T0), after 3 months (T1) and after at least 2 years (range 24-32 months) (T2) using a questionnaire assessing bowel function, the Bristol scale, and two validated questionnaires on quality of life: the CHQ-PF50 questionnaire for the parents of patients aged 6-11 years and the SF36 questionnaires for patients aged between 12 and 18 years.

RESULTS

Seventy-two patients completed TAI program in T1, and 67 continued into T2. Bowel outcomes (constipation and fecal incontinence) improved in both the SB and the ARM groups in the short and mid-long term. In both groups at T1 and T2, parents and children reported an improvement in quality of life and there was a significant increase of stool form types 4 and 5 as described by the Bristol scale. Common adverse effects during the study were similar at T1 and T2 without serious complications.

CONCLUSIONS

We observed a sustained improvement in bowel management and quality of life in SB and ARM children during the study, more significant in the short term than in mid-long term. To maintain success rates in the mid-long term and to reduce the dropout rate, we propose patient training and careful follow-ups.

Bowel management in children with spina bifida

Spina bifida is a birth defect that commonly causes bowel and bladder dysfunction in children with a significant negative impact on quality of life and emotional wellbeing. Fecal continence improves satisfaction and the quality of life of both children and their caretakers. Bowel management in children with spina bifida is hampered by limited controlled studies and variable practice within different institutions and subspecialists. The goals of a successful bowel management program in children with spina bifida consist of predictable bowel movements, social continence, and eventual independence. Treatment options range from conservative interventions such as diets and oral laxatives that modify stool consistency and transit, to trans-anal irrigations and antegrade continence enemas that facilitate predictable recto-sigmoid emptying and provide a greater degree of independence. In children, the treatment approach should be implemented in the context of the child's developmental age in order to allow for optimum social integration with their age-appropriate peers. We present a review of a stepwise approach to bowel management in children with spina bifida and the challenges related to the proposed treatment options.

Self-efficacy beliefs, faecal incontinence and health-related quality of life in patients born with anorectal malformations

AIM

Anorectal malformations (ARMs) are rare congenital colorectal anomalies with long lasting consequences, among which faecal incontinence is one of the most relevant since it may strongly affect patients' health-related quality of life (HRQoL). Although a growing body of literature supports the importance of self-efficacy in chronic disease health outcomes, only few studies have focused on self-efficacy in ARMs and in faecal incontinence. The purpose of the present study is to examine the mediational role of self-efficacy in the path between faecal incontinence and HRQoL in patients born with ARMs.

METHOD

Ninety-eight adult patients from the Italian Association for Anorectal Malformations (AIMAR) responded to measures of faecal incontinence, self-efficacy for managing ARM consequences, and physical and mental HRQoL (SF-36). Data were analysed by means of structural equation models.

RESULTS

The tested model provides support for the guiding hypothesis. Fit indices indicate that the model fits the data well (χ²  = 33.48, df = 23, P = 0.07; comparative fit index [CFI] = 0.97; root mean square error of approximation [RMSEA] = 0.07; standardized root mean square residual [SRMR] = 0.05). Faecal incontinence has negative effects on both physical and mental HRQoL, as well on self-efficacy. In turn, self-efficacy has a positive and direct effect on mental HRQoL.

CONCLUSION

Faecal incontinence is the most relevant and negative factor influencing HRQoL; in addition, self-efficacy contributes in reducing emotional distress and in improving mental health outcomes. Longitudinal and controlled studies may be helpful to evaluate the effectiveness of self-efficacy interventions in improving mental HRQoL in patients with faecal incontinence.
