Outcomes in Hirschsprung's disease with coexisting learning disability

Long-Term Functional Outcomes and Multidisciplinary Management after Ileorectal Duhamel Pull-Through for Total Colonic Aganglionosis-20-Year Experience in a Tertiary Surgical Center

INTRODUCTION

 Management of patients with total colonic aganglionosis (TCA) is challenging for pediatric surgeons. The purpose of this study was to review our institution's 20-year experience regarding long-term outcomes and multidisciplinary team management of these patients after an ileorectal Duhamel pull-through procedure.

MATERIALS AND METHODS

 Retrospective review was conducted for all patients diagnosed with TCA in our tertiary institution. Data were collected on demographics, clinical presentation, complications, need for additional surgery, and long-term effects on bowel function.

RESULTS

 Of a total of 202 patients with Hirschsprung's disease, 13 were diagnosed with TCA (6.4%). Clinical presentation was variable. Eleven presented in neonatal period with distal bowel obstruction and two presented with constipation in early infancy. Ileorectal Duhamel pull-through was performed in all patients. Median follow-up was 13 years. Eleven are toilet trained, of whom five are fully continent. Six continue to have problems with bowel continence or constipation. One developed recurrent episode of Hirschsprung's associated enterocolitis. Two patients had stoma re-established. Patients experiencing difficulties in bowel function are jointly managed by a multidisciplinary team consisting of surgeons, gastroenterologists, pediatric psychologists, and clinical nurse specialists.

CONCLUSION

 TCA can be associated with significant long-term morbidity. Nearly half of the patients in this series have ongoing problems with bowel continence requiring a permanent stoma in some. Diligent follow-up coupled with inputs of a multidisciplinary team has greatly helped manage these complex patients in our institution.

A multi-center cross-sectional comparison of parent-reported quality of life and bowel function between anorectal malformation and Hirschsprung's disease patients with versus those without Down syndrome

PURPOSE

Down syndrome (DS) is a common abnormality associated with anorectal malformation (ARM) and Hirschsprung's disease (HD). However, quality of life (QOL) in ARM and HD patients with DS is under-researched. This study compares parent-reported QOL and bowel function in ARM and HD patients with DS to those without.

METHODS

Between December 2020 to February 2023, parents of ARM and HD patients with and without DS aged 3-17 years who had undergone surgery > 12 months prior at four tertiary referral centers were recruited. We used the Pediatric Quality of Life Inventory™ (PedsQL™) Generic Core Scales, General Well-Being (GWB) Scale and Family Impact (FI) Module questionnaires, and the Rintala bowel function score (BFS).

RESULTS

There were 101 ARM, 9 (8.9%) of whom had DS; and 87 HD, of whom 6 (6.9%) had DS. Parent-reported Core scores in ARM and HD with DS were comparable to those without DS. However, ARM and HD with DS had worse scores in the FI Module and bowel function than those without DS.

CONCLUSION

Although parent-reported QOL in ARM and HD with DS is similar to those without DS, family impact and BFS are worse. Our findings are limited by small sample size in proportion of DS patients.

Transitional Care in Patients With Hirschsprung Disease: Those Left Behind

BACKGROUND

The long-term effects of Hirschsprung disease are clinically variable. An improved understanding of challenges patients may face as adults can help inform transitional care management.

OBJECTIVE

To explore the outcomes and transitional care experiences in adult patients with Hirschsprung.

DESIGN

Cohort study.

SETTING

Single center.

PATIENTS

All patients treated for Hirschsprung between 1977 and 2001 (aged older than 18 years at the time of survey distribution in July 2018-2019). Eligible patients were sent validated multidomain surveys and qualitative questions regarding their transitional care.

MAIN OUTCOME MEASURES

Status of transitional care, bowel function, and quality-of-life assessment. Qualitative analysis of transitional care experience.

RESULTS

Of 139 patients, 20 had received transition care (10 had at least 1 visit but had been discharged and 10 were receiving ongoing follow-up). These patients had inferior bowel function and quality-of-life scores at follow-up. Twenty-three patients (17%) had issues with soiling at the time of discharge, and 7 patients received transitional care. Of these 23 patients, 9 (39%) had a normal Bowel Function Score (17 or more), 5 (22%) had a poor score (less than 12), and 1 had since had a stoma formation. Eighteen patients (13%) had active moderate-severe issues related to bowel function, only 5 had been transitioned, and just 2 remained under ongoing care. Importantly, when these patients were discharged from our pediatric center, at a median age of 14 (interquartile range, 12-16) years, 10 of 17 patients had no perceptible bowel issues, suggesting a worsening of function after discharge.

LIMITATIONS

The retrospective design and reliance on clinical notes to gather information on discharge status as well as patient recall of events.

CONCLUSIONS

There remains a small but significant proportion of Hirschsprung patients for whom bowel function either remains or becomes a major burden. These results support a need to better stratify patients requiring transitional care and ensure a clear route to care if their status changes after discharge. See Video Abstract .

ATENCIN DE TRANSICIN EN PACIENTES CON ENFERMEDAD DE HIRSCHSPRUNG, LOS QUE SE QUEDAN ATRS

ANTECEDENTES:Los efectos a largo plazo de la enfermedad de Hirschsprung son clínicamente variables. Una mejor comprensión de los desafíos que los pacientes pueden enfrentar cuando sean adultos puede ayudar a informar la gestión de la atención de transición.OBJETIVO:Explorar los resultados y las experiencias de atención de transición en pacientes adultos con Hirschsprung.DISEÑO:Estudio de cohorte.AJUSTE:Unico centro.PACIENTES:Todos los pacientes tratados por Hirschsprung 1977-2001 (edad >18 años en el momento de la encuesta, Julio de 2018-2019). A los pacientes elegibles se les enviaron encuestas multidominio validadas, así como preguntas cualitativas sobre su atención de transición.PRINCIPALES MEDIDAS DE RESULTADOS:Estado de la atención de transición, función intestinal y evaluación de la calidad de vida. Análisis cualitativo de la experiencia de cuidados transicionales.RESULTADOS:De 139 pacientes, 20 habían recibido atención de transición (10 tuvieron al menos una visita pero habían sido dados de alta y 10 estaban recibiendo seguimiento continuo). Estos pacientes tenían puntuaciones inferiores de función intestinal y calidad de vida en el seguimiento. Veintitrés (17%) pacientes tuvieron problemas para ensuciarse en el momento del alta y 7 recibieron atención de transición. De estos, 9/23 (39%) tenían una puntuación de función intestinal normal (≥17), 5/23 (22%) tenían una puntuación baja (<12) y un paciente había tenido desde entonces una formación de estoma. Dieciocho (13%) pacientes tenían problemas activos de moderados a graves relacionados con la función intestinal, solo cinco habían realizado la transición y solo 2 permanecían bajo atención continua. Es importante destacar que cuando estos pacientes fueron dados de alta de nuestro centro pediátrico, a una edad promedio de 14 [RIQ 12-16] años, 10/17 no tenían problemas intestinales perceptibles, lo que sugiere un empeoramiento de la función después del alta.LIMITACIONES:El diseño retrospectivo y la dependencia de notas clínicas para recopilar información sobre el estado del alta, así como el recuerdo de los eventos por parte del paciente.CONCLUSIÓN:Sigue existiendo una proporción pequeña pero significativa de pacientes con Hirschsprung para quienes la función intestinal permanece o se convierte en una carga importante. Estos resultados respaldan la necesidad de estratificar mejor a los pacientes que requieren atención de transición y garantizar una ruta clara hacia la atención si su estado cambia después del alta.

A Narrative Review of Patient-Reported Outcome Measures and Their Application in Recent Pediatric Surgical Research: Advancing Knowledge and Offering New Perspectives to the Field

INTRODUCTION

 Patient-reported outcome measures (PROMs) can be employed in both research and clinical care to enhance our understanding of outcomes that matter to patients. This narrative review aims to describe PROM use in recent pediatric surgical research, identify and describe psychometrically robust PROMs, providing an overview of those derived from pediatric patient input, and make recommendations for future research.

MATERIALS AND METHODS

 A search was conducted to identify articles published from 2021 to August 2023 describing the availability and/or use of at least one valid or reliable PROM in children with conditions including anorectal malformations, biliary atresia, congenital diaphragmatic hernia, duodenal atresia, esophageal atresia, abdominal wall defects, Hirschsprung's disease, sacrococcygeal teratoma, and short bowel syndrome. Articles were categorized based on their objectives in applying PROMs. Psychometrically robust PROMs were identified and described.

RESULTS

 Out of the 345 articles identified, 49 met the inclusion criteria. Seventeen focused on esophageal atresia and 14 on Hirschsprung's disease. Twenty-nine PROMs were identified, with 12 deemed psychometrically robust. Seven psychometrically robust PROMs were developed using patient input in the primary item generation. Most PROMs were applied to advance understanding of conditions and/or treatment and fewer were developed or psychometrically evaluated. No PROMs were assessed for their impact or incorporated into an implementation study.

CONCLUSIONS

 This review reveals gaps in the application of PROMs in recent pediatric surgical research. Emphasis should be placed on the development and utilization of psychometrically robust PROMs, broadening the scope of covered diseases, conducting impact assessments, and evaluating implementation strategies.

Imbalanced dietary patterns, anthropometric, and body composition profiles amongst adults with Down syndrome

Introduction: We aimed to analyze the anthropometric and body composition profiles of Down syndrome (DS) adults; to describe their dietary habits, nutrient intake, and physical activity patterns; and to identify the related risk factors which may influence their health status and quality of life.Methods: A cross-sectional study was conducted on a cohort of 23 DS adults (45% women) aged 21-44 years. Anthropometry and body composition were assessed by bioelectrical impedance. Dietary nutrient intake was assessed quantitatively using a 72-h recall. A food frequency questionnaire and the prevention with Mediterranean diet-PREDIMED questionnaire were used for qualitative rating.Results: Higher fat mass (FM) and lower lean mass (LM), bone mass (BM), and waist to hip ratio (WHR) were observed in women compared to men. LM and BM decreased, and body mass index (BMI), FM, and WHR increased with aging (all P < 0.05). Vitamin D and iodine intakes were not met by 70% and 60% of the studied participants, respectively. A total of 82% of the participants consumed less than 5 portions of fruits and vegetables per day and overconsumed food groups such as sweets and snacks and red meat (> 2 times per week). Protein intake showed a significant positive correlation with height (r = 0.489, P < 0.05), whereas fat intake was positively correlated with sweets and snacks (r = 0.521, P < 0.05).Conclusion: The present findings support the existence of poor anthropometric and body composition profiles, and diet quality, underscoring the need for an interdisciplinary team assessment to enhance health and quality of life in DS adults.

Short and Long-Term Outcomes in Hirschsprung Disease: Are the Syndrome-Associated Patients Really Doing Worse?

INTRODUCTION

Given the lack of data to help caregivers in the follow-up of Hirschsprung disease (HD), this study aimed to compare the functional outcomes of isolated Hirschsprung disease (I-HD) to syndrome-associated Hirschsprung disease (SA-HD) at 1, 3, 5, and 10 years.

METHODS

A retrospective chart review of patients diagnosed with HD between January 1990 and May 2021 at our pediatric center was performed to collect data on patient characteristics, investigations, and treatments. Ninety-five patients were identified, of whom 76 were included in the study. SA-HD is defined as a syndrome known to be associated with HD or cognitive impairment.

RESULTS

Patient characteristics were comparable between groups ( P > 0.05). There were 52 patients with I-HD and 24 with SA-HD. The patients median age was 9 days at diagnosis and 1.5 month at surgery. SA-HD patients became bowel continent at a significantly older age (mean age 8.43 vs 4.94 years, P = 0.0471) and received more bowel continence medications. At 5 years, SA-HD patients requiring ≥2 medications for bowel continence represented 54.5% versus 11.1% of I-HD patients ( P = 0.009). Lastly, SA-HD patients had urinary incontinence at a significantly older age ( P = 0.0136, 5 years).

CONCLUSION

Clinicians should be aware that SA-HD patients are more prone to bladder dysfunction and became bowel continent at an older age than I-HD patients. They need more and prolonged bowel management medications, and other important complications need to be addressed in patient care. These results should prompt a longer follow-up period for these patients, especially in SA-HD.

Hirschsprung disease

Hirschsprung disease (HSCR) is a rare congenital intestinal disease that occurs in 1 in 5,000 live births. HSCR is characterized by the absence of ganglion cells in the myenteric and submucosal plexuses of the intestine. Most patients present during the neonatal period with the first meconium passage delayed beyond 24 h, abdominal distension and vomiting. Syndromes associated with HSCR include trisomy 21, Mowat-Wilson syndrome, congenital central hypoventilation syndrome, Shah-Waardenburg syndrome and cartilage-hair hypoplasia. Multiple putative genes are involved in familial and isolated HSCR, of which the most common are the RET proto-oncogene and EDNRB. Diagnosis consists of visualization of a transition zone on contrast enema and confirmation via rectal biopsy. HSCR is typically managed by surgical removal of the aganglionic bowel and reconstruction of the intestinal tract by connecting the normally innervated bowel down to the anus while preserving normal sphincter function. Several procedures, namely Swenson, Soave and Duhamel procedures, can be undertaken and may include a laparoscopically assisted approach. Short-term and long-term comorbidities include persistent obstructive symptoms, enterocolitis and soiling. Continued research and innovation to better understand disease mechanisms holds promise for developing novel techniques for diagnosis and therapy, and improving outcomes in patients.

Transition Zone Pull-through in Patients with Hirschsprung Disease: Is Redo Surgery Beneficial for the Long-term Outcomes?

INTRODUCTION

Transition zone pull-through (TZPT) is incomplete removal of the aganglionic bowel/transition zone (TZ) in patients with Hirschsprung disease (HD). Evidence on which treatment generates the best long-term outcomes is lacking. The aim of this study was to compare the long-term occurrence of Hirschsprung associated enterocolitis (HAEC), requirement of interventions, functional outcomes and quality of life between patients with TZPT treated conservatively to patients with TZPT treated with redo surgery to non-TZPT patients.

METHODS

We retrospectively studied patients with TZPT operated between 2000 and 2021. TZPT patients were matched to two control patients with complete removal of the aganglionic/hypoganglionic bowel. Functional outcomes and quality of life was assessed using Hirschsprung/Anorectal Malformation Quality of Life questionnaire and items of Groningen Defecation & Continence together with occurrence of Hirschsprung associated enterocolitis (HAEC) and requirement of interventions. Scores between the groups were compared using One-Way ANOVA. The follow-up duration lasted from time at operation until follow-up.

RESULTS

Fifteen TZPT-patients (six treated conservatively, nine receiving redo surgery) were matched with 30 control-patients. Median duration of follow-up was 76 months (range 12-260). No significant differences between groups were found in the occurrence of HAEC (p = 0.65), laxatives use (p = 0.33), rectal irrigation use (p = 0.11), botulinum toxin injections (p = 0.06), functional outcomes (p = 0.67) and quality of life (p = 0.63).

CONCLUSION

Our findings suggest that there are no differences in the long-term occurrence of HAEC, requirement of interventions, functional outcomes and quality of life between patients with TZPT treated conservatively or with redo surgery and non-TZPT patients. Therefore, we suggest to consider conservative treatment in case of TZPT.

Sexual function and lower urinary tract symptoms after minimally invasive endorectal pull-through in adolescent males with Hirschsprung disease

BACKGROUND

Effects of colorectal resection on sexual function and the lower urinary tract are inadequately studied in patients with Hirschsprung disease (HD). This study aimed to increase existing knowledge on sexual function and lower urinary tract symptoms (LUTS) in HD male adolescents operated with minimally invasive endorectal pull-through (ERPT).

METHODS

Non-syndromic male adolescents (12-18 years) operated with ERPT were invited to participate in this single-center cross-sectional study which included a semi-structured interview on sexual function and LUTS, a questionnaire recording LUTS, and a urodynamic study. Uroflowmetry curves were eligible for evaluation if the voided volume was >50% of expected bladder capacity. Ethical approval and informed consent were obtained.

RESULTS

Of 37 eligible male adolescents, 35 (95%) with a median age of 14.9 (12.0 -18.3) years were included. 94% had rectosigmoid aganglionosis, and 97% underwent a minimally invasive ERPT. 34 (97%) visited the outpatient clinic. The ability to get erections and to ejaculate was assessed in 25/35 (71%) adolescents. 25/25 (100%) could get an erection, and of adolescents ≥15 years 14/15 (93%) could ejaculate. 32 (91%) returned the questionnaire and underwent urodynamic studies. 15/32 (47%) reported LUTS, but most had only sporadic LUTS. 31/32 (97%) were highly satisfied with their bladder function. Sporadic urinary incontinence was reported by 4/32 (13%), but none reported social problems due to this. Of the eligible 28/32 (88%) uroflowmetry curves, 15/28 (54%) were normal.

CONCLUSIONS

Minimally invasive ERPT seems to preserve sexual function and does not induce lower urinary tract symptoms in adolescent HD males.

Colostomy Delays Cell Loss in the Brain and Improves Juvenile Survival in a Neonatal Rat Model of Hirschsprung's Disease

Hirschsprung's disease is a congenital malformation characterized by the absence of enteric ganglia in the distal intestine and gut obstruction. Our previous study indicates the brain pathology during the disease progression. A subpopulation of Hirschsprung's disease patients is also associated with anomalies of the central nervous system. In the investigation, we studied a rat model of Hirschsprung's disease, known as spotting lethal (sl/sl) ETB-/- rats, which carries a spontaneous deletion in endothelin receptor B (human gene name: EDNRB) and manifests a similar phenotype as humans with Hirschsprung's disease. Homozygous mutant sl/sl rats were successfully rescued from premature death by performing colostomy and dramatically survived to their juvenile age. By the body weight measured, their body growth was not revealed to be significantly different between ETB-/- and wildtype ETB+/+ or heterozygous (+/sl) ETB+/- groups while all underwent the same colostomy. Cell loss was investigated in several brain regions by using terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay (TUNEL) in ETB+/+, ETB-/-, and ETB+/- rats. Number of TUNEL-positive cells in the cerebellum and the hippocampus of ETB-/- rats was significantly increased compared with that of the ETB+/+ and ETB+/- rats. TUNEL-positive cells were observed in the molecular layer and granular cell layers of the cerebellum. In contrast, no significant difference in the density of TUNEL-positive cells was revealed in the cerebral cortex. These results suggest that either endothelin receptor B sl mutation or colostomy has predominant lasting effects on the cell survival/loss in the cerebellum and hippocampus of adult ETB-/- rats. Our findings provide the information on cellular changes in the brains of patients with Hirschsprung's disease due to congenital EDNRB mutation as well as clinically relevant interventions.

Hirschsprung disease outcomes

Hirschsprung disease (HD) is a complex surgical and medical problem that appears to have varied health and social outcomes with the age and neurodevelopmental state of patients. In general, long-term outcomes are thought to be good for the majority of patients despite recognized problems with constipation and/or fecal incontinence. However, there are no universally accepted pathways regarding post-operative bowel management programs nor clearly defined follow-up pathways making the current outcome measures difficult to interpret. Further, other factors that may influence outcome including age at the time of procedure and procedure type continue to lack consensus. Improved support of children in resource limited environments and during periods of transition into the adult medical care environment are needed to improve outcome.  Recent proliferation of multidisciplinary care teams and consortia may help to better understand outcomes and address current knowledge gaps. Continuing these collaborations will be imperative to continuing improvements in care which may ultimately impact outcome.
