Bowel function and associated risk factors at preschool and early childhood age in children with anorectal malformation type rectovestibular fistula: An ARM-Net consortium study

The relationship between the caregiver burden and quality of life in parents of Turkish children with anorectal malformation or Hirschsprung's disease

BACKGROUND

Anorectal malformation (ARM) or Hirschsprung's disease (HD) in children impact on parents' burden of care and quality of life (QoL). The aim of this study was to investigate the relationship between caregiver burden and QoL in parents of children with ARM or HD.

DESIGN AND METHODS

This cross-sectional study was conducted with 51 parents who completed the Zarit Burden Inventory (ZBI) and World Health Organization Quality of Life Scale-Short Form Turkish Version (WHOQOL-BREF-TR).

RESULTS

The mean (±SD) ZBI score was 33.6 (±12.7), and 47.1% of parents (n = 24) perceived their caregiver burden as mild, 31.4% (n = 16) as moderate, and 3.9% (n = 2) as severe. According to the multivariate linear regression, associated anomalies (β1 = 5.912), family income (β1 = -6.007), stoma care (β1 = 8.287), and diagnosis were identified to be significant determinants of caregiver burden. A negative, moderate, and significant relationship was identified between the ZBI scores and the physical domain (r = -0.417, p < .01), psychological domain (r = -0.421, p < .01), social relations domain (r = -0.398, p < .01), and environmental domain (r = -0.495, p < .01) scores of the WHOQOL-BREF-TR.

CONCLUSIONS

The mothers perceived their caregiver burden as mild. However, a significant number of parents suffer from moderate to heavy caregiver burden. An increase in the caregiver burden of parents reduces their quality of life.

PRACTICE IMPLICATIONS

Heightened awareness of the potential for caregiver burden and its association with quality of life among parents of children with ARM and HD may contribute to improved.

Correlation between congenital pelvic floor muscle development assessed by magnetic resonance imaging and postoperative defecation

OBJECTIVE

Children with congenital anorectal malformation (CAM) experience challenges with defecation. This study aims to assess defecation in preschool-age children with CAM and to evaluate the correlation between pelvic floor muscle developed assessed by magnetic resonance imaging (MRI) and postoperative defecation.

METHODS

We collected clinical data and MRI results from 89 male children with CAM. The bowel function scores for children with Perineal (cutaneous) fistula, Rectourethral fistula(Prostatic or Bulbar), and Rectovesical fistula were computed. MRI scans were subjected to image analysis of the striated muscle complex (SMC). The association between pelvic floor muscle score and bowel function score was examined using the Cochran-Armitage Trend Test.

RESULTS

We observed that 77.4% of the SMC scores by MRI for Perineal fistula were good. The Rectourethral fistula SMC score was 40.6% for moderate and 59.4% for poor. The SMC score for Rectovesical fistula was 100% for moderate. Furthermore, 77.4% of patients with Perineal fistula had bowel function scores (BFS) ≥ 17 points. Among those with Rectourethral fistula and Rectovesical fistula, 12.5% and 0 had BFS ≥ 17 points, respectively. An analysis of muscle development and bowel function in patients with Rectovesical fistula, Rectourethral fistula, and Perineal fistula revealed a correlation between SMC development and BFS. Subgroup analysis showed that the Perineal fistula had statistical significance; however, the Rectourethral fistula and Rectovesical fistula were not statistically significant.

CONCLUSION

A correlation exists between pelvic floor muscle development and postoperative defecation in children with Perineal fistula.

Assessment of long-term quality of life, bowel and voiding function outcomes in patients with anorectal malformation at a single UK centre

AIMS

Assess long-term quality of life (QoL), bowel and voiding function in anorectal malformation (ARM) paediatric patients.

METHOD

Retrospective review of ARM patients between 2007 and 2020 was performed. QoL (all patients), bowel and voiding function (> 5 yo) were assessed using the paediatric quality of life inventory (PedsQL), paediatric incontinence and constipation score (PICS) and dysfunctional voiding scoring system (DVSS), respectively.

RESULTS

There were 122 patients (49% female, 85 > 5 yo) with ARM. Two had died, four refused, twenty-two were non-contactable, leaving ninety-four patients (65 > 5 yo) included. Mean age was 89 months (19-183), and follow-up was 86 months (13-183). Patients had significantly poorer scores for QoL, bowel and voiding function compared to published healthy controls. 57% had poor bowel function, 32% had poor voiding function and 38% required 'ancillary aids' to facilitate function. Patients using 'ancillary aids' for voiding function had a significantly lower QoL (parent: 62 vs 77; p = 0.01, patient: 66 vs 79; p = 0.05). Bowel continence was worse in those with high vs low ARM (13 vs 20, p = 0.004) and timely vs delayed diagnosis (17 vs 24, p = 0.04).

CONCLUSION

Patients with ARM have significantly worse QoL, bowel and voiding function than normal healthy controls. There is a need for long-term monitoring of function and further support for these children.

Does sacral ratio have any impact on success rate of biofeedback therapy in children with lower urinary tract dysfunction?

INTRODUCTION

To evaluate the possible impact of patients' sacral ratios (SRs) on response to biofeedback (BF) therapy in pediatric patients with lower urinary tract dysfunction (LUTD).

MATERIALS AND METHODS

In this retrospective cohort conducted from 2016 to 2018 in our tertiary medical center, we included the medical records of all pediatric patients with LUTD who were nominated for BF due to having abnormal uroflowmetry patterns and simultaneous increase in electromyography (EMG) activity. Ten sessions of weekly animated BF were performed for each patient. All patients underwent a complete urological evaluation, uroflowmetry with simultaneous EMG and post-void residual measurement before and after treatment. SRs were calculated based on plain anteroposterior lumbosacral radiographs. Patients were then divided into normal SR (≥0.74) and low SR (<0.74) and outcomes were compared between them.

RESULTS

Of the total 86 patients included in our study, 48 (55.8%) had a normal SR (≥0.74), while 38 (44.2%) had a low SR (<0.74). Our data revealed that BF therapy significantly improved maximum and average urinary flow rates, urine volume, daytime urinary incontinence, enuresis, urinary urgency and constipation; irrespective of the patients' SRs (all P < 0.001). Our between-groups analyses showed that after the completion of BF, the SR ≥ 0.74 group had significantly higher maximum urinary flow rate (mean difference [95%CI]: 7.7 [5.4, 10.0], P < 0.001) (Figure) and urine volume (mean difference [95%CI]: 49.9 [19.5, 80.4], P = 0.002) and significantly lower diurnal urinary incontinence (4.2% vs. 21.1%, P = 0.020), enuresis (4.2% vs. 18.4%, P = 0.040) and constipation (2.1% vs. 23.7%, P = 0.004) compared to the SR < 0.74 group.

DISCUSSION

SR has been proposed as a reliable indicator of bony pelvis growth and subsequent lumbosacral neurodevelopment. Additionally, larger SR values are associated with better postoperative sphincter function in children with urological and anorectal malformations. Our results demonstrated that after completion of BF, the normal SR group had a significantly better improvement of some of the uroflowmetry indicators and LUTD-associated symptoms compared to the low SR group.

CONCLUSION

Our findings implied that although BF therapy is an efficient treatment for children with LUTD, irrespective of their sacral development; children with enhanced sacral development may benefit from better clinical response, especially in terms of LUTD-associated symptoms.

Bowel function and features of bowel dysfunction in preschool children with anorectal malformation type rectoperineal and rectovestibular fistula

Anorectal malformations (ARMs) of the rectoperineal and rectovestibular fistula type (RPF/RVF) generally have a good prognosis but may be accompanied by bowel dysfunction, especially constipation. Bowel dysfunction in preschoolers may persist into adolescence and adulthood, exerting a negative effect on their quality of life. This study was designed to evaluate bowel function and identify the features of bowel dysfunction in preschoolers with RPF/RVF across type and sex differences. A total of 159 preschoolers with RPF/RVF (male RPF group, n = 95; female RPF group, n = 26; RVF, n = 38) and 128 normal control preschoolers (control group, n = 128; female control group, n = 35), according to the bowel function score (BFS) obtained through a questionnaire survey, the BFS items in the questionnaire, and the clinical characteristics of patients were compared among groups. The rates of bowel dysfunction (BFS < 17) were 27.2% and 50.0% in the RPF and RVF groups, respectively. Normal rates of BFS items, namely, ability to hold back defecation, feels/reports of the urge to defecate, frequency of defecation, and constipation, in the RPF and RVF groups were significantly lower than those in the control and female control groups (all p < 0.05). After subgroup analysis among the male RPF, female RPF, and RVF groups, higher rates of normal bowel function and ability to hold back defecation were found in the male RPF group than in the female RPF and RVF groups (p < 0.05). Normal rates of feels/reports of the urge to defecate were higher in the male and female RPF groups than in the RVF group (all p < 0.05). The rate of never soiling in the male RPF group was significantly higher than that in the RVF group (p < 0.05).  Conclusions: In patients with RPF/RVF, bowel dysfunction is still prevalent, characterized by inadequate ability to hold back defecation, inability to feel/report the urge to defecate, soil, less frequent defecation, and constipation. However, male RPF patients had better overall bowel function than female RPF or RVF patients, including more adequate ability to hold back defecation and feels/reports of the urge to defecate and slighter soiling, which may be linked to early age at surgery, low occurrences of low sacral ratio, and tethered cord in male RPF.  Trial registration: This study was retrospectively registered in ClinicalTrials.gov on 09/01/2023 (NCT05716230). What is Known: • Rectoperineal and rectovestibular fistula (RPF/RVF) of the anorectal malformation (ARM) type has a good prognosis but may cause bowel dysfunction, especially constipation. • Bowel dysfunction at preschool age may lead to social and psychological disorders that undermine the quality of life in adolescence and adulthood. What is New: • Bowel function in preschoolers with RPF/RVF was deeply evaluated in a relatively large number of patients and normal control children. • Features of bowel dysfunction in RPF/RVF preschoolers across type and gender differences were identified in this study.

A Quality Assessment of the ARM-Net Registry Design and Data Collection

BACKGROUND

Registries are important in rare disease research. The Anorectal Malformation Network (ARM-Net) registry is a well-established European patient registry collecting demographic, clinical, and functional outcome data. We assessed the quality of this registry through review of the structure, data elements, collected data, and user experience.

MATERIAL AND METHODS

Design and data elements were assessed for completeness, consistency, usefulness, accuracy, validity, and comparability. An intra- and inter-user variability study was conducted through monitoring and re-registration of patients. User experience was assessed via a questionnaire on registration, design of registry, and satisfaction.

RESULTS

We evaluated 119 data elements, of which 107 were utilized and comprised 42 string and 65 numeric elements. A minority (37.0%) of the 2278 included records had complete data, though this improved to 83.5% when follow-up elements were excluded. Intra-observer variability demonstrated 11.7% incongruence, while inter-observer variability was 14.7%. Users were predominantly pediatric surgeons and typically registered patients within 11-30 min. Users did not experience any significant difficulties with data entry and were generally satisfied with the registry, but preferred more longitudinal data and patient-reported outcomes.

CONCLUSIONS

The ARM-Net registry presents one of the largest ARM cohorts. Although its collected data are valuable, they are susceptible to error and user variability. Continuous evaluations are required to maintain relevant and high-quality data and to achieve long-term sustainability. With the recommendations resulting from this study, we call for rare disease patient registries to take example and aim to continuously improve their data quality to enhance the small, but impactful, field of rare disease research.

Evaluation of Anal Sphincter with High Resolution Anorectal Manometry and 3D Reconstruction in Patients with Anorectal Malformation

BACKGROUND

Patients with anorectal malformation (ARM) need long-term follow-up, in order to evaluate fecal continence; the main predictors of longer-term success are the type of ARM, associated anomalies and sacral integrity. Three-Dimensional High Resolution Anorectal Manometry (3D-HRAM) gives detailed information on pressure on the anal complex profile. Our objective was to analyze anal sphincter activity in ARM patients with 3D-HRAM establishing the correlation between manometric and clinical data.

METHODS

Forty ARM patients were submitted to 3D-HRAM: manometric, anatomical and clinical scores were correlated with each other and with the bowel management response (BM).

RESULTS

A positive correlation between all scores and types of ARM was found: in high ARM and in patients with spinal anomalies (regardless to ARM type) lower scores were reported and even after BM they did not achieve good continence.

CONCLUSIONS

3D-HRAM gives detailed data on the functional activity of the anal sphincter complex. Our study revealed a correlation between manometric parameters and clinical outcomes, confirming spinal malformations and ARM type as the most important prognostic risk factors for a bad outcome. Specific sphincteric defects can also be explored with manometry, allowing for tailored bowel management strategies.

Children with an Anorectal Malformation Going to Primary School: The Parent's Perspective

BACKGROUND

Continence problems occur often in children with anorectal malformations (ARM). The aim of this study was to evaluate parental experiences with toilet facilities at Dutch primary schools and their experience with how schools deal with ARM children.

METHODS

This survey was developed in collaboration with the national patient advocacy group (PAG). Recruitment for participation was conducted by the PAG (email listing and social media) and one expertise center for ARM. Participants were parents of school-attending ARM children aged 3 to 12 years.

RESULTS

Sixty-one participants (31.9%) responded to the survey. The median age of the children was 7.0 years (IQR 5.0-9.0). Schools were often located in a village (63.9%) and encompassed 100-500 children (77.0%). In total, 14 parents (23.0%) experienced difficulties in finding a primary school. Experiences with the school were described as solely positive (37.7%), solely negative (9.8%), positive and negative (34.4%), and neither positive nor negative (16.4%). Regarding school toilet facilities, 65.6% of the toilets were reported clean and 78.7% were easily accessible.

CONCLUSIONS

About 25% of parents reported difficulties in enrolling their children into primary school, and 45% reported negative experiences. This highlights the need for improved guidance and the optimization of education in schools when dealing with ARM children.

Negative emotions and quality of life of parents with children diagnosed with anorectal malformations

PURPOSE

To investigate the anxiety, depression, stress, and quality of life of parents with children diagnosed with anorectal malformations.

METHODS

68 parents participated in the study and completed the unified Self-Rating Anxiety Scale, Self-Rating Depression Scale, Perceived Stress Scale, and the World Health Organization Quality of Life-BREF.

RESULTS

Compared with the Chinese reference values, parents in our study had higher scores on anxiety and depression and lower scores on the psychological and environmental domain of the World Health Organization Quality of Life-BREF. Parents who live in rural areas, pay for medical treatment out of pocket, and have multiple children are prone to feel anxious. Parents with multiple children also scored worse in the domains of physiology, psychology, social relationships, and general quality of life assessment. They scored significantly lower in the domains of psychology and social relationships when parents had a low education level. Parents of children who had undergone staged operations got lower scores on the general quality of life assessment.

CONCLUSIONS

Parents of children with anorectal malformations have varying degrees of psychological and emotional problems that require attention in the clinic.

Bowel function at preschool and early childhood age in children with long-segment Hirschsprung disease

Bowel dysfunction has been proven to be the most typical complication of long-segment Hirschsprung disease (LSHD). Additionally, bowel dysfunction in preschool and early childhood should be properly assessed, because it may result in persistent bowel dysfunction, social issues, and depression in adolescence and adulthood. This study evaluated bowel function during preschool and early childhood in patients with LSHD. A cross-sectional bowel function score (BFS) questionnaire survey was conducted on 270 infants with short-segment Hirschsprung disease (SSHD) and LSHD who underwent pull-through (PT) between January 2014 and December 2019 at the Children's Hospital of Nanjing Medical University. One hundred ninety patients who consented to the survey were asked to complete the questionnaire and were divided into two groups: the LSHD group (n = 42) and the SSHD group (n = 148). Bowel function outcomes were assessed by using a questionnaire. The total BFS score in the LSHD group was significantly lower than that in the SSHD group (15.0 [14.0, 17.0] vs. 18.0 [16.0, 19.0], p < 0.05) and did not improve with age (p > 0.05). Independent BFS items with lower scores were discovered in LSHD than in SSHD, including the capacity to hold back defecation, feeling/reporting the urge to defecate, frequency, soiling, and accidents (all p < 0.05). After subgroup analysis of follow-up age (3-5 years, 5 ~ 7 years, and > 7 years), there was no difference between the score of ability to hold back defecation over 7 years old and feeling/reporting the urge to defecate over 5 years old (all p > 0.05). The frequency and soiling scores were lower in the LSHD group than in the SSHD group over 5 years of age (all p < 0.05). Fortunately, there was no difference in constipation scores and social problems between the LSHD and SSHD groups in every sub-follow-up group (all p > 0.05).  Conclusion: Overall, bowel function at preschool and early childhood age was poorer in LSHD than in SSHD and did not improve with age. However, the ability to hold back defecation and feeling/reporting the urge to defecate with age in LSHD may be similar to those in SSHD. Simultaneously, the frequency, soiling, and number of accidents were consistently worse in the LSHD group.  Trial registration: This study was retrospectively registered in the ClinicalTrials database.gov (NCT05461924) in August 2022. What is Known: • Bowel function in SSHD is satisfactory or near-normal, and the general consensus is that the longer the aganglionic segment, the worse the bowel function after surgery. • Bowel functional outcomes of LSHD were not defined, and the limited reports of bowel functional outcomes compared with SSHD were extensively varied. Bowel dysfunction at preschool and early childhood may lead to persistent bowel dysfunction, social problems, and depression in adolescence or adulthood. What is New: • Bowel function in preschool and early childhood in patients with LSHD has not been defined and should be thoroughly assessed in a larger group of patients with precise definitions of incontinence or soiling. • The present study was primarily designed to evaluate bowel function at preschool and early childhood age in LSHD compared with SSHD in a relatively large number of HD cases using BFS.

Long-term functional outcomes of patients with Hirschsprung disease following pull-through

BACKGROUND

Hirschsprung disease (HSCR) is a common congenital disorder presenting with functional obstruction due to aganglionosis of the colon. There are numerous types of pull-through surgery for managing HSCR, such as transabdominal endorectal (Soave), Swenson, Duhamel, transanal endorectal pull-through (TEPT), and laparoscopic (Georgeson) approach. Here, we aimed to describe the long-term outcome of patients with HSCR who underwent transabdominal Soave, Duhamel, and TEPT in our institution.

METHODS

We performed a cross-sectional analysis for patients who underwent Duhamel, Soave, and TEPT at our institution from January 2012 to December 2015. Long-term functional outcome was determined by bowel function score (BFS). The BFS was obtained by interviewing patients who had completed at least three years of follow-up.

RESULTS

Twenty-five patients were included in this study who underwent transabdominal Soave (n = 8), Duhamel (n = 4), and TEPT (n = 13). There were 24 patients with short aganglionosis type. The median age of HSCR diagnosis was 10 (IQR = 1-39) months, while the median age of pull-through surgery was 17 (IQR = 7-47) months. The median follow-up of BFS level for HSCR patients after pull-through was 72 (IQR, 54-99) months. There were 11 patients with good BFS level and 10 patients with normal BFS level. Additionally, 50% of Duhamel patients had poor BFS level, while 50% of Soave patients had good BFS level, and 54% of TEPT patients had normal BFS level (p = 0.027). As many as 50% of Duhamel patients showed daily soiling and required protective aids, while 38.5% of TEPT had staining less than 1/week and no change of underwear required, and 50% of Soave patients revealed no soiling, respectively (p = 0.030). Furthermore, 75% of Duhamel patients had accidents, while 75% of Soave and 46.2% of TEPT patients had no accidents (p = 0.035).

CONCLUSION

Our study shows that the type of definitive surgery might affect the long-term bowel functional outcome; particularly, the TEPT approach might have some advantages over the transabdominal Soave and Duhamel procedures.
