Bowel Function and Quality of Life After Transanal Endorectal Pull-through for Hirschsprung Disease: Controlled Outcomes up to Adulthood

Total Transanal Endorectal Pull-through Versus Laparoscopic-Assisted Approach in Children with Rectosigmoid Hirschsprung's Disease: A Systematic Review and Meta-Analysis

Objective: To compare the clinical outcomes between total transanal endorectal pull-through (TTEPT) and laparoscopic-assisted transanal endorectal pull-through (LTEPT) in children with rectosigmoid Hirschsprung's disease. Methods: A retrospective study was conducted to compare patients with rectosigmoid Hirschsprung's disease who underwent TTEPT or LTEPT at Beijing Children's Hospital between January 2016 and June 2021. Clinical details were collected from medical records. Patients' parents completed the Krickenbeck questionnaire to evaluate the long-term bowel function (age >4 years) by telephone. A literature search was conducted by using the National Center for Biotechnology Information (NCBI) PubMed database. We combined data from our data with eligible articles and performed a meta-analysis. Result: From our data, there was no difference in the incidence of postoperative complications or long-term bowel function between the patients undergoing TTEPT and LTEPT. A meta-analysis, including five published articles and our data, was performed with a total of 414 patients (n = 236 with TTEPT and n = 178 with LTEPT). For postoperative complications, there were no significant differences between TTEPT and LTEPT for the incidence of HAEC (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.45-1.80; P = .77) or anastomotic leak (OR, 2.52; 95% CI, 0.40-15.80; P = .32). Regarding bowel function outcomes, the incidence of soiling (OR, 1.77; 95% CI, 0.84-3.71; P = .13) and constipation (OR, 1.20; 95% CI, 0.54-2.64; P = .66) were also similar for the two approaches. Conclusion: There was no significant difference in postoperative complications and bowel functional outcomes in patients with rectosigmoid HD undergoing TTEPT or LTEPT. Levels of Evidence: III.

Causes and consequences: development and pathophysiology of Hirschsprung disease

Hirschsprung disease (HSCR) is a congenital enteric neuropathy in which the enteric nervous system (ENS) fails to develop along variable lengths of the distal gastrointestinal (GI) tract. This aganglionosis results in a functional bowel obstruction and requires surgical resection of the aganglionic segment. Despite surgery, however, long-term bowel dysfunction affects many patients. Understanding the embryologic causes and pathophysiologic consequences of HSCR is critical to improving its diagnosis and treatment. During normal gut development, the ENS arises from neural crest cells (NCCs) that delaminate from the neural tube to populate the entire GI tract with enteric neurons and glia. This process requires NCCs to undergo proliferation, migration and differentiation to form the complex neuroglial network that regulates gut motility and other intestinal functions. This review discusses the cellular and molecular processes that control normal ENS formation and what goes awry to give rise to HSCR. The complex pathophysiologic consequences of aganglionosis are discussed, including recent observations that describe novel aspects of HSCR beyond the absence of ganglion cells. This review aims to expand the understanding of HSCR and to stimulate new ideas on how to improve current management of the disease.

Bowel Function Score in Long-Term Follow-Up for Children with Hirschsprung Disease: OASIS-Holistic Care in Hirschsprung Disease Network Position Paper

INTRODUCTION

The assessment of bowel function in patients with Hirschsprung disease (HD) remains controversial, as several different bowel function scores are used in the literature and are therefore not suitable for reliable comparison. Conference Section: The OASIS-Holistic Care in Hirschsprung Disease Network Group addressed this issue and evaluated the most commonly used scores for their utility in HD patients. Scoping Review and Expert Group Consensus were performed. It was agreed that the ideal score for patients with Hirschsprung disease should be a comprehensive, validated score that allows reliable assessment of bowel function and continence, depicts changes according to management and natural history, and quantifies baseline parameters. This score should also enable comparisons of bowel function in patients born with HD worldwide.

CONCLUDING REMARKS

The OASIS-Holistic Care in Hirschsprung Disease Network Group agreed that this ideal score does not yet exist and is therefore a future goal of the group. Meanwhile, clinicians should use a score for comparable, standardized, objective assessment, and the Rintala Score is suggested. Future developments may also lead to easily accessible patient-reported outcome measures and semi-automated dashboards that allow automated data extraction from electronic health records.

Long-term outcomes and quality of life in patients with Hirschsprung disease

Although patients with Hirschsprung disease are mostly affected by imperfect bowel function and fecal control in the long term, they are also predisposed to lower urinary tract symptoms, impaired sexual functions, infertility, psychosocial issues, and decreased quality of life. Rare, but notable comorbidities, which may manifest after childhood, include inflammatory bowel disease and familial medullary thyroid cancer. Despite frequent occurrence of fecal incontinence and constipation, the overall long-term outlook is quite optimistic as social continence with a good quality of life can be achieved by efficient bowel management also in those affected patients, whose self-coping strategies and medical treatment remain insufficient. Bowel dysfunction and other potential long-term complications are best managed by an interdisciplinary specialized approach not overlooking psychosocial issues, which also helps to correctly identify areas requiring continuing input by adult healthcare for young adult patients after transition. Additional research is needed to unravel the pathophysiological mechanisms of the long-term bowel dysfunction to identify novel therapeutic targets for development of more efficient innovative management strategies and thereby improvement of quality of life.

Treatment of Persistent Soiling in Hirschsprung Disease With Antegrade Continence Enemas

INTRODUCTION

Patients with Hirschsprung disease (HD) can experience soiling after their pull-through. We evaluated the use of antegrade continence enema (ACE) for this patient population and investigated the timing and factors associated with getting the patient clean.

METHODS

We performed a single-institution retrospective review (from January 2020 to January 2023) of patients with HD and prior pull-through who had persistent soiling, failed laxative treatment or rectal enemas, and were treated with antegrade enemas. The primary outcome was time to become "clean of stool" which was defined as at least one bowel movement per day, no more than one stool accident per week, and no significant stool burden radiographically. Kaplan-Meier survival analysis was performed, and univariate cox proportional hazard regression was used to assess factors associated with time to continence.

RESULTS

Thirty patients who met the criteria underwent ACE creation at a median age of 6.5 y (interquartile range 5.3-9.8) with a median follow-up time of 11.5 mo (interquartile range 5.6-16.5). Most patients became clean by 4 mo (13 of 20, 65%) with similar results at 1-y follow-up (16 of 21, 76%). The median time to becoming clean was 4.3 mo (95% confidence interval: 1.7-15.0. Patients with hypermotility were more likely to continue to soil at 1 y (80% versus 13%, P = 0.01). There were no additional factors significantly associated with time to cleanliness.

CONCLUSIONS

ACE is a useful modality for HD patients with soiling. Most became clean of stool in 4 mo. The presence of hypermotility was associated with a higher incidence of persistent soiling at 1 y.

Surgical outcomes for patients with rectosigmoid hirschsprung disease who underwent transanal endorectal pull-through after 1 year of age

PURPOSE

This study aimed to compare the differences in postoperative complications and long-term bowel function outcomes between patients with rectosigmoid Hirschsprung disease (HD) who underwent transanal endorectal pull-through (TEPT) beyond infancy (age> 1 year of age) and those during infancy (≤ 1 year of age).

METHODS

All patients with rectosigmoid HD at Beijing Children's Hospital between January 2011 and December 2020 were analyzed retrospectively. They were divided into two groups based on age at TEPT: group A was defined as patients who performed TEPT beyond infancy (age>1 year of age), and group B as patients who performed TEPT during infancy (age ≤ 1 year of age). Clinical details were collected from medical records. Bowel function outcomes were assessed by the Rintala questionnaire (age ≥ 4 years).

RESULTS

A total of 339 patients were included: 216 (63.7%) who operated with TEPT beyond infancy (group A) and 123 (36.3%) during infancy (group B). Regarding postoperative complications, all patients suffering anastomosis leakage following TEPT (7/216, 3.2%) occurred in group A, and the rate of anastomosis leakage in group A was significantly higher than in group B (3.2% vs. 0.0%, p = 0.044). 228 patients (228/327, 69.7%) completed the Rintala questionnaire. There was no significant difference in long-term bowel function outcomes between the two groups.

CONCLUSION

Compared with patients who performed TEPT during infancy, those beyond infancy are more likely to suffer anastomosis leakage. however, the long-term bowel function outcomes seem comparable.

TYPE OF STUDY

A retrospective single-center study.

Influence of Diet on Bowel Function and Abdominal Symptoms in Children and Adolescents with Hirschsprung Disease-A Multinational Patient-Reported Outcome Survey

Introduction: This study aimed to understand the influence of diet and nutrition items on gastrointestinal symptoms in patients with Hirschsprung Disease (HD). Method: An online questionnaire was created to obtain patient-reported outcomes using the multinational Holistic Care in Hirschsprung Disease Network. This was distributed in Dutch, English, German, Italian, Polish, and Swedish via patient associations. Information on demographics, the extension of disease, current diet, and the influence of food ingredients on bowel function were obtained. Results: In total, 563 questionnaires were answered by parents or patients themselves. The length of the aganglionic segment was short in 33%, long in 45%, total colonic aganglionosis (TCA) in 11%, and involved the small intestine in 10%. Overall, 90% reported following a mixed diet, and 31% reported taking probiotics, with twice as many patients taking probiotics in the TCA group compared to standard HD. Mealtimes and behaviours around eating were affected by 61%, while 77% had established food items that worsened symptoms, and of these, 80% stated that they had worked these items out themselves. A high-fibre diet was followed by 24% and 18% a low-fibre diet. Symptoms were reported, particularly from dairy in 30%, fruits in 39%, pulses in 54%, and sugar in 48%. Conclusions: This first multinational survey on diet and bowel function in HD reports an association between certain dietary items with gastrointestinal symptoms. This study can support an improved understanding of the interaction between food items and bowel function in children with HD. We suggest a multidisciplinary approach to balance dietary exclusions and support adequate growth, preventing nutrition deficiencies and enhancing quality of life.

Transanal Endorectal Pull-Through for Hirschsprung's Disease: Complications and Lessons from Our Practice and the Literature

BACKGROUND/OBJECTIVES

Hirschsprung's disease (HD) is a congenital disorder characterised by the absence of ganglion cells in the distal bowel, resulting in functional obstruction. The transanal endorectal pull-through (TEPT) procedure, a minimally invasive approach, aims to treat HD by removing the aganglionic segment. This study assessed the feasibility, safety, and efficacy of single-stage TEPT in paediatric patients, focusing on postoperative complications, bowel function, and quality of life.

METHODS

A retrospective cohort study was conducted on 150 children who underwent single-stage TEPT from January 2005 to December 2023 at the Medical University of Gdansk. Data were collected from medical records, including demographics, preoperative assessments, surgical details, postoperative management, and follow-up outcomes. Statistical analyses were performed using Microsoft Excel 365 and the programming language Python 3.12. The mean age at surgery was 13 months, with a male-to-female ratio of 2.75:1. The mean operative time was 129 min, and the mean hospital stay was seven days.

RESULTS

Postoperative complications included anastomotic leak (4%), wound infections (15%), and enterocolitis (26%). Redo surgeries were required in 18% of cases due to persistent constipation and obstructive symptoms. This article includes a comprehensive review of the literature.

CONCLUSIONS

TEPT demonstrates a favourable safety profile and efficacy in treating HD, though significant concerns include complications such as enterocolitis and the need for additional surgeries. Surgical expertise and thorough preoperative and postoperative management are crucial to optimising patient outcomes.

Approach to Constipation in Children: Recommendations for Evaluation and Management

Constipation is common in childhood, and most patients can be successfully managed by their primary care provider. However, some patients will require more specialized management either due to an underlying congenital colorectal disorder such as Hirschsprung disease or anorectal malformation or due to severe functional constipation that is refractory to medical management.

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.

Hirschsprung's disease. Management

BACKGROUND

Hirschsprung's disease (HD) is a rare congenital disease that is characterised by the absence of ganglion cells in the myenteric plexus starting in the distal bowel. This results in distal functional obstruction and may lead to complications like enterocolitis. The treatment is surgical and requires the resection of the aganglionic segment, and the pull-through of normal intestine into the anal opening. However, even after successful surgery, patients may continue to have symptoms.

AIM

Discuss current surgical techniques and management strategies for patients with postoperative symptoms after surgical correction of Hirschsprung's disease.

METHODS

A review of the literature was done through PubMed, with a focus on clinical management and approach.

RESULTS

We describe the clinical problems that can occur after surgical correction. These include obstructive symptoms, enterocolitis, or faecal incontinence. A systematic approach for the evaluation of these patients includes the exclusion of anatomic, inflammatory, behavioural or motility related factors. Depending on the severity of the symptoms, the evaluation includes examination under anaesthesia, the performance of contrast studies, endoscopic studies, measurement of anal sphincter function and colonic motility studies. The treatment is focused towards addressing the different pathophysiological mechanisms, and may include medical management, botulinum toxin to the anal sphincter or rarely redo-operation.

CONCLUSIONS

Patients with Hirschsprung's disease need to have surgical correction, and their postoperative long-term management is complex given a variety of associated problems that can occur after surgery. A systematic evaluation is necessary to provide appropriate therapy.

Anorectal malformation and Hirschsprung's disease: a cross-sectional multicentre comparison of quality of life and bowel function to a healthy population

PURPOSE

Children with anorectal malformation (ARM) and Hirschsprung's disease (HD) often experience bowel symptoms into adulthood, despite definitive surgery. This study evaluates the quality of life (QOL) and bowel functional outcome of children treated for ARM and HD in comparison to healthy controls.

METHODS

Between December 2020 and February 2023, we recruited patients with ARM and HD aged 3-17 years at four tertiary referral centres, who had primary corrective surgery done >12 months prior. Healthy controls were age-matched and sex-matched. All participants completed the Pediatric Quality of Life Inventory Generic Core Scales 4.0, General Well-Being (GWB) Scale 3.0 and Family Impact (FI) Module 2.0 Questionnaires. Bowel Function Score (BFS) Questionnaires were also administered. We also performed subgroup analysis according to age categories. Appropriate statistical analysis was performed with p<0.05 significance. Ethical approval was obtained.

RESULTS

There were 306 participants: 101 ARM, 87 HD, 118 controls. Patients with ARM and HD had significantly worse Core and FI Scores compared with controls overall and in all age categories. In the GWB Scale, only ARM and HD adolescents (13-17 years) had worse scores than controls. ARM and HD had significantly worse BFSs compared with controls overall and in all age categories. There was significant positive correlation between BFS and Core Scores, GWB Scores and FI Scores.

CONCLUSION

Patients with ARM and HD had worse QOL than controls. Lower GWB Scores in adolescents suggests targeted interventions are necessary. Bowel function influences QOL, indicating the need for continuous support into adulthood.

Sacral neuromodulation in children and adolescents with defecation disorders

BACKGROUND

Even if understanding of neuronal enteropathies, such as Hirschsprung's disease and functional constipation, has been improved, specialized therapies are still missing. Sacral neuromodulation (SNM) has been established in the treatment of defecation disorders in adults. The aim of the study was to investigate effects of SNM in children and adolescents with refractory symptoms of chronic constipation.

METHODS

A two-centered, prospective trial has been conducted between 2019 and 2022. SNM was applied continuously at individually set stimulation intensity. Evaluation of clinical outcomes was conducted at 3, 6, and 12 months after surgery based on the developed questionnaires and quality of life analysis (KINDLR). Primary outcome was assessed based on predefined variables of fecal incontinence and defecation frequency.

KEY RESULTS

Fifteen patients enrolled in the study and underwent SNM (median age 8.0 years (range 4-17 years)): eight patients were diagnosed with Hirschsprung's disease (53%). Improvement of defecation frequency was seen in 8/15 participants (53%) and an improvement of fecal incontinence in 9/12 patients (75%). We observed stable outcome after 1 year of treatment. Surgical revision was necessary in one patient after electrode breakage. Urinary incontinence was observed as singular side effect of treatment in two patients (13%), which was manageable with the reduction of stimulation intensity.

CONCLUSIONS

SNM shows promising clinical results in children and adolescents presenting with chronic constipation refractory to conservative therapy. Indications for patients with enteral neuropathies deserve further confirmation.

Bowel Management in Hirschsprung Disease-Pre-, Peri- and Postoperative Care for Primary Pull-Through

(1) Background: Bowel management contributes throughout the pathway of care for children with Hirschsprung. Preoperative bowel management prepares the child and family for the pull-through surgery. Perioperative bowel management supports early recovery and tailored bowel management in the follow-up supports the achievement of social continence. (2) Methods: We conducted a cross-sectional assessment of our institutional bowel management program to illustrate the pre-, peri- and postoperative bowel management strategies. (3) Results: A total of 31 children underwent primary pull-through, 23 without a stoma and 8 with a stoma, at a median age of 9 months. All children without a stoma were prepared for surgery by using rectal irrigations. Children with a stoma were prepared for surgery with a transfer of stoma effluent. Transanal irrigation supported early recovery. (4) Conclusions: Bowel management is a key pillar of the management of children with Hirschsprung disease. Incorporating bowel management in the pathway of care facilitates primary pull-through and supports perioperative recovery.

Major surgical conditions of childhood and their lifelong implications: comprehensive review

BACKGROUND

In recent decades, the survival of children with congenital anomalies and paediatric cancer has improved dramatically such that there has been a steady shift towards understanding their lifelong health outcomes. Paediatric surgeons will actively manage such conditions in childhood and adolescence, however, adult surgeons must later care for these 'grown-ups' in adulthood. This article aims to highlight some of those rare disorders encountered by paediatric surgeons requiring long-term follow-up, their management in childhood and their survivorship impact, in order that the adult specialist may be better equipped with skills and knowledge to manage these patients into adulthood.

METHODS

A comprehensive literature review was performed to identify relevant publications. Research studies, review articles and guidelines were sought, focusing on the paediatric management and long-term outcomes of surgical conditions of childhood. The article has been written for adult surgeon readership.

RESULTS

This article describes the aforementioned conditions, their management in childhood and their lifelong implications, including: oesophageal atresia, tracheo-oesophageal fistula, malrotation, short bowel syndrome, duodenal atresia, gastroschisis, exomphalos, choledochal malformations, biliary atresia, Hirschsprung disease, anorectal malformations, congenital diaphragmatic hernia, congenital lung lesions and paediatric cancer.

CONCLUSION

The increasing survivorship of children affected by surgical conditions will translate into a growing population of adults with lifelong conditions and specialist healthcare needs. The importance of transition from childhood to adulthood is becoming realized. It is hoped that this timely review will enthuse the readership to offer care for such vulnerable patients, and to collaborate with paediatric surgeons in providing successful and seamless transitional care.

Impact of Colorectal Nurse Specialist supervised parental administration of rectal washouts on Hirschsprung's disease outcomes: a retrospective review

PURPOSE

To highlight the utility of Colorectal Nurse Specialist (CNS) supervised parental administration of rectal washouts in the management of Hirschsprung's disease (HD).

METHODS

Retrospective case note review of HD patients treated at a tertiary children's hospital in United Kingdom from January 2011 to December 2022. Data collected included demographics, complications, enterocolitis, obstructive symptoms and stomas. Primary pull-through (PT) is done 8-12 weeks after birth. Parental expertise in performing rectal washouts at home is ensured by our CNS team before and after PT.

RESULTS

PT was completed in 69 of 74 HD patients. Rectal washouts were attempted on 63 patients before PT. Failure of rectal washout efficacy necessitated a stoma in four patients (6.4%). Of the 65 patients who had PT and stoma closed, three (4.5%) required a further stoma over a mean follow-up period of 57 months (Range 7-144 months). Two of these had intractable diarrhoea due to Total Colonic Aganglionosis (TCA). One patient (1.5%) had unmanageable obstructive symptoms requiring re-diversion. Hirschsprung-associated enterocolitis (HAEC) requiring hospital admission occurred in 14 patients (21%).

CONCLUSION

Our stoma rates are lower compared to recent UK data. This could potentially be due to emphasis on parental ability to perform effective rectal washouts at home under CNS supervision.

Nomogram for soiling prediction in postsurgery hirschsprung children: a retrospective study

PURPOSE

The aim of this study was to develop a nomogram for predicting the probability of postoperative soiling in patients aged greater than 1 year operated for Hirschsprung disease (HSCR).

MATERIALS AND METHODS

The authors retrospectively analyzed HSCR patients with surgical therapy over 1 year of age from January 2000 and December 2019 at our department. Eligible patients were randomly categorized into the training and validation set at a ratio of 7:3. By integrating the least absolute shrinkage and selection operator [LASSO] and multivariable logistic regression analysis, crucial variables were determined for establishment of the nomogram. And, the performance of nomogram was evaluated by C-index, area under the receiver operating characteristic curve, calibration curves, and decision curve analysis. Meanwhile, a validation set was used to further assess the model.

RESULTS

This study enrolled 601 cases, and 97 patients suffered from soiling. Three risk factors, including surgical history, length of removed bowel, and surgical procedures were identified as predictive factors for soiling occurrence. The C-index was 0.871 (95% CI: 0.821-0.921) in the training set and 0.878 (95% CI: 0.811-0.945) in the validation set, respectively. And, the AUC was found to be 0.896 (95% CI: 0.855-0.929) in the training set and 0.866 (95% CI: 0.767-0.920) in the validation set. Additionally, the calibration curves displayed a favorable agreement between the nomogram model and actual observations. The decision curve analysis revealed that employing the nomogram to predict the risk of soiling occurrence would be advantageous if the threshold was between 1 and 73% in the training set and 3-69% in the validation set.

CONCLUSION

This study represents the first efforts to develop and validate a model capable of predicting the postoperative risk of soiling in patients aged greater than 1 year operated for HSCR. This model may assist clinicians in determining the individual risk of soiling subsequent to HSCR surgery, aiding in personalized patient care and management.

Clinical utility of anal sphincter relaxation integral in water-perfused and solid-state high-resolution anorectal manometry

BACKGROUND/PURPOSE

We investigated the diagnostic performance of the anal sphincter relaxation integral (ASRI) for infants with Hirschsprung's disease (HD).

METHODS

We performed water-perfused high-resolution anorectal manometry (HRAM) in 18 infants (9 with HD), and solid-state HRAM in another 18 infants (4 with HD). We calculated the ASRI during the rectoanal inhibitory reflex (RAIR) maneuver at pressure cutoffs of <10 mmHg (ASRI 10) and <15 mmHg (ASRI 15). We investigated the diagnostic performance of the ASRI for HD in infants undergoing water-perfused and solid-state HRAM.

RESULTS

HD infants who underwent either water-perfused or solid-state HRAM had significantly lower ASRI 10 and ASRI 15 values, compared with non-HD infants (P < 0.05 and P < 0.05, respectively). Using the water-perfused HRAM system, ASRI 10 and ASRI 15 values of <7 and <29 mmHg s.cm, respectively, exhibited good diagnostic performance for HD (88.89% and 88.89%, respectively). Receiver operating characteristic curve analysis indicated that ASRI 10 and ASRI 15 values of <5.5 and <20 mmHg s.cm, respectively, were optimal for the diagnosis of HD infants when using the solid-state HRAM system, with high diagnostic accuracies of 83.33% and 83.33%, respectively.

CONCLUSION

ASRI may assist the diagnosis of HD infants using either water-perfused or solid-state HRAM. These systems require different catheter-specific ASRI cutoffs for the prediction of 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.

Post-surgical Outcomes of Different Surgical Techniques in Hirschsprung's Disease: A Literature Review

Hirschsprung's disease (HD) is a rare condition that affects newborns and is characterized by the lack of ganglion cells in the colon. Typical symptoms include difficulty passing stool, vomiting, and trouble feeding. Various surgical methods are available to manage the condition. The aim of the study is to investigate and compare the post-surgical outcomes of different surgical techniques used in the treatment of HD. A thorough literature search was conducted using various electronic databases to identify relevant studies to be referred to. Double-blinded screening of the identified articles led to the final selection of 40 out of 440 HD, including transanal endorectal pull-through (TERPT), laparoscopic approaches, and modified techniques. Several studies have investigated surgical procedures for HD, including TERPT, laparoscopic methods, and modified techniques. These have shown positive outcomes, with fewer complications, improved bowel function, and favorable cosmetic results. Individual patient characteristics and surgeon expertise should guide procedure selection. Surgery for HD aims to restore normal bowel function, but post-surgical outcomes can include constipation or fecal incontinence. Complications like enterocolitis, anastomotic stricture, and sphincter damage may occur. Laparoscopic approaches have shorter hospital stays. However long-term follow-up is essential to assess quality of life, psychological well-being, and potential side effects.

Histopathology of Ganglion Cells in the Proximal Resected Bowel Correlates With the Clinical Outcome in Hirschsprung Disease: A Pilot Study

INTRODUCTION

Intraoperative leveling biopsy by identifying ganglion cells is crucial to determine surgical margin during surgery for Hirschsprung disease (HSCR). The anastomosis should be performed at least 5 cm proximal to the ganglionic segment to prevent transition zone pull-through. However, the length of the transition zone could be much longer than expected and the histological evaluation of the entire circumference of the proximal margin is recommended, which is time-consuming and not applicable for leveling biopsy. We found that the histopathologic features of ganglion cells varied in the examined bowel specimens and demonstrated a pattern similar to immature and degenerated neuron cells. We assumed that the histopathologic features of ganglion cells in the proximal resected bowel were associated with the clinical outcome and might guide the leveling biopsy. In this study, we described a histopathologic grade of ganglion cells based on the degree of maturity and degeneration. We assessed the correlation between the histopathological grade of ganglion cells in the proximal surgical margin and clinical outcome.

METHODS

Three hundred fifty seven patients with HSCR treated between 2013 and 2020 were included. The ganglion cells were divided into six grades based on the histopathologic features in frozen sections. Medical records and detailed histopathologic results of intraoperative frozen sections were reviewed. Follow-up data were collected to evaluate clinical outcomes. The pediatric incontinence and constipation scoring system was used to predict bowel function.

RESULTS

The histopathologic results of proximal resected bowel from 357 HSCR patients were presented as follows: Grade I in 52 patients (14.6%), Grade II in 186 patients (52.1%), Grade III in 107 patients (30.0%), and Grade IV in 12 patients (3.4%). The median follow-up time was 46.8 mo (13.0-97.6 mo). The histopathologic grade of ganglion cells from the proximal resected margin was significantly related to postoperative constipation problems and the incidence of Hirschsprung-associated enterocolitis. The results from the pediatric incontinence and constipation scoring system indicated a positive correlation between better postoperative bowel function and lower histopathologic grade of ganglion cells.

CONCLUSIONS

This pilot study showed an association between the histopathologic features of ganglion cells in the proximal surgical margin and the clinical outcome. It may provide additional information for intraoperative pathologic consultation in leveling biopsy to prevent insufficient resection of the affected colon. A prospective study is warranted to validate these findings before clinical application.

Long-term bowel function after single-stage transanal endorectal pull-through in neonatal patients with Hirschsprung disease

BACKGROUND

The aim of this study was to assess long-term outcomes of neonatal patients with Hirschsprung disease (HD) after single-stage transanal endorectal pull-through (TEPT) and to explore the predictive factors contributing to subnormal bowel function.

METHODS

Patients aged > 3 years operated for HD with TEPT during neonatal period between 2007 and 2019 answered the bowel function score (BFS) questionnaire. The patients were retrospectively divided into two groups according to whether they had normal bowel function. The clinical variables were compared between the subnormal and normal BFS groups. Univariate and multivariable logistic regression analysis were performed to identify the predictive factors contributing to subnormal bowel function.

RESULTS

A total of 160 children (71.7%) were included in this study, with mean follow-up time of 7.3 years (range 3.0-15.1 years). The level of aganglionosis were determined to be the short-segment (124/160, 77.5%), long-segment (33/160, 20.6%), and TCA (3/160, 1.9%). One hundred and thirty-four patients (83.8%) had a BFS ≥ 17, and 26 patients (16.2%) with subnormal bowel function (BFS < 17). Univariate and multivariate logistic regression analysis showed that level of aganglionosis with long-segment or TCA and postoperative hospital stay > 8.5 days were independent risk factors with OR of 3.213 (1.252, 8.246) and 3.813 (1.371, 10.606) for subnormal BFS, respectively.

CONCLUSION

Most HD patients who underwent one-stage TEPT in the neonatal period have favorable long-term results, and the level of aganglionosis with long-segment or TCA and long postoperative hospital stay may be closely related to subnormal bowel function.

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.

Robotic-assisted proctosigmoidectomy for Hirschsprung’s disease: A multicenter prospective study

BACKGROUND

Robotic surgery is a cutting-edge minimally invasive technique that overcomes many shortcomings of laparoscopic techniques, yet few studies have evaluated the use of robotic surgery to treat Hirschsprung’s disease (HSCR).

AIM

To analyze the feasibility and medium-term outcomes of robotic-assisted proctosigmoidectomy (RAPS) with sphincter- and nerve-sparing surgery in HSCR patients.

METHODS

From July 2015 to January 2022, 156 rectosigmoid HSCR patients were enrolled in this multicenter prospective study. Their sphincters and nerves were spared by dissecting the rectum completely from the pelvic cavity outside the longitudinal muscle of the rectum and then performing transanal Soave pull-through procedures. Surgical outcomes and continence function were analyzed.

RESULTS

No conversions or intraoperative complications occurred. The median age at surgery was 9.50 months, and the length of the removed bowel was 15.50 ± 5.23 cm. The total operation time, console time, and anal traction time were 155.22 ± 16.77, 58.01 ± 7.71, and 45.28 ± 8.15 min. There were 25 complications within 30 d and 48 post-30-d complications. For children aged ≥ 4 years, the bowel function score (BFS) was 17.32 ± 2.63, and 90.91% of patients showed moderate-to-good bowel function. The postoperative fecal continence (POFC) score was 10.95 ± 1.04 at 4 years of age, 11.48 ± 0.72 at 5 years of age, and 11.94 ± 0.81 at 6 years of age, showing a promising annual trend. There were no significant differences in postoperative complications, BFS, and POFC scores related to age at surgery being ≤ 3 mo or > 3 mo.

CONCLUSION

RAPS is a safe and effective alternative for treating HSCR in children of all ages; it offers the advantage of further minimizing damage to sphincters and perirectal nerves and thus providing better continence function.

hPSC-derived sacral neural crest enables rescue in a severe model of Hirschsprung's disease

The enteric nervous system (ENS) is derived from both the vagal and sacral component of the neural crest (NC). Here, we present the derivation of sacral ENS precursors from human PSCs via timed exposure to FGF, WNT, and GDF11, which enables posterior patterning and transition from posterior trunk to sacral NC identity, respectively. Using a SOX2::H2B-tdTomato/T::H2B-GFP dual reporter hPSC line, we demonstrate that both trunk and sacral NC emerge from a double-positive neuro-mesodermal progenitor (NMP). Vagal and sacral NC precursors yield distinct neuronal subtypes and migratory behaviors in vitro and in vivo. Remarkably, xenografting of both vagal and sacral NC lineages is required to rescue a mouse model of total aganglionosis, suggesting opportunities in the treatment of severe forms of Hirschsprung's disease.

Anorectal manometry findings in relation with long-term functional outcomes of the patients operated on for Hirschsprung's disease compared to the reference-based population

PURPOSE

This study investigated anorectal manometry (AM) findings and bowel function of patients operated on for Hirschsprung's disease (HD).

METHODS

A cross-sectional study was conducted at Children's Hospital 2. Patients operated on for HD from January 2015 to January 2020 were reviewed. Their clinical characteristics, bowel function, and manometric findings were investigated and compared with the references.

RESULTS

Ninety-five patients and 95 references were enrolled. Mean ages were 6.6 ± 2.2 years and 7.2 ± 2.9 years,; fecal incontinence rates were 25.3% and 2.1%, and constipation rates were 12.6% and 4.2 for the patients versus the references, respectively. Anal resting pressures were significantly decreased in the patients compared to the references (53.2 ± 16.1 mmHg versus 62.2 ± 14.0 mmHg; p < 0.05). Among the patients, the anal resting pressure was significantly decreased in the incontinents than in the continents (46.0 ± 10.6 mmHg versus 55.6 ± 16.9 mmHg, p < 0.05). During the sensation test, the value of maximum tolerated volume was significantly decreased in the incontinents than in the continents (135.9 ± 47.9 mL versus 166.6 ± 58.3 mL, p < 0.05).

CONCLUSION

AM is an objective method providing beneficial information that could guide a more adapted management in HD patients with defecation disorders.

Clinical and manometric evaluation of postoperative anorectal function in patients after trans-anal pull-through for Hirschsprung disease

Background

Transanal endorectal pull-through (TEPT) surgery is a new trend in the treatment of Hirschsprung disease, and evaluating its functional outcome is difficult. The purpose of this study is to evaluate the defecation pattern after TEPT surgery in pediatrics.

Material and methods

In this cross-sectional survey, 40 patients with Hirschsprung disease were studied. They underwent a one-stage transanal pull-through procedure from May 2007 till April 2015 in Namazi hospital by the same surgeon. All the patients had the aganglionic segment in the rectosigmoid, confirmed by pre-operation barium enema and post-operation histopathology. The patients were 40 children with mean operation age of 36.6 months old. The success rate of surgery was evaluated by following the questionnaire form. Clinical evaluation with bowel function score and anorectomanometry were carried out.

Result

One hundred percent of them had a daily stool. Eighty-five percent of patients never experienced pain during defecation, 10% experienced occasional pain, and the rest felt pain with every defecation. Just one case (5%) reported using a laxative. Regarding improvements after the operation, 75% were completely okay, 20% felt much better, and 5% reported some improvements. The average National Health Service score was 8.375, which seems satisfactory. The mean average anal sphincter in the group with soiling was 39.67 and in the group without soiling was 34.83, which is in the normal range in both groups, and there was no significant difference between these groups (P > 0.05).

Conclusion

The defecation pattern after TEPT surgery were satisfactory in almost all cases, even in infancy. Most patients had satisfactory manometry and clinical result.

Nationwide outcomes of newborns with rectosigmoid versus long-segment Hirschsprung disease

PURPOSE

Hirschsprung Disease (HD) is a common congenital intestinal disorder. While aganglionosis most commonly affects the rectosigmoid colon (rectosigmoid HD), outcomes for patients in which aganglionosis extends to more proximal segments (long-segment HD) remain understudied. This study sought to compare postoperative outcomes among newborns with rectosigmoid and long-segment HD.

METHODS

The Nationwide Readmission Database was queried from 2016 to 2018 for newborns with HD. Newborns were stratified into those with rectosigmoid or long-segment HD. Those who received no rectal biopsy or pull-through procedure during their newborn hospitalization were excluded. A propensity score-matched analysis (PSMA) of newborns with either type of HD was constructed utilizing 17 covariates including demographics, comorbidities, and congenital-perinatal conditions.

RESULTS

There were 1280 newborns identified with HD (82% rectosigmoid HD, 18% long-segment HD). Patients with rectosigmoid HD had higher rates of laparoscopic resections (35% vs. 12%) and less frequently received a concomitant ostomy (14% vs. 84%), both p < 0.001. Patients with long-segment HD were more likely to have a delayed diagnosis (12% vs. 5%) and require multiple bowel operations (19% vs. 4%), both p < 0.001. They experienced higher rates of complications, including small bowel obstructions (10% vs. 1%), infections (45% vs. 20%), and Hirschsprung-associated enterocolitis (11% vs. 5%), all p < 0.001. After PSMA, newborns with long-segment HD were found to have a longer length of stay and higher hospitalization costs.

CONCLUSION

Newborns with long-segment HD experience significant delays in diagnosis, surgery, and complications compared to those with rectosigmoid HD. This information should be utilized to improve healthcare delivery for this patient population.

Long-term Bowel function and pediatric health-related quality of life after transanal rectal mucosectomy and partial internal anal sphincterectomy pull-through for Hirschsprung Disease

OBJECTIVE

The aim of this study was to define controlled outcomes for bowel function and quality of life (QoL) after transanal rectal mucosectomy and partial internal anal sphincterectomy pull-through (TRM-PIAS, A modified Swenson procedure) for Hirschsprung disease (HD).

BACKGROUND

We have previously shown that a novel modification of transanal rectal mucosectomy and partial internal anal sphincterectomy (TRM-PIAS, A modified procedure) for Hirschsprung disease have the advantage of low postoperative Hirschsprung associated enterocolitis. The controlled long-term follow-up studies evaluating Bowel Function Score (BFS) and Pediatric Quality of Life Inventory (PedsQoL, age <18 years) remain unclear.

METHODS

Between Jan 2006 and Jan 2016, 243 Patients underwent TRM-PIAS older than 4 years were included, while experienced redo surgery because of complication were excluded. Patients were compared with age- and gender-matched 244 healthy children each randomly selected from the 405 general population. The enrollee was investigated for questionnaires on BFS and PedsQoL.

RESULTS

One hundred and ninety-nine (81.9%) patients' representatives for the entire study population responded. The mean age of patients was 84.4 months (48-214 months). Compared with controls, patients reported impairment of hold back defecation, fecal soiling, and the urge to defecate (P < 0.05), and no significantly different in fecal accidents, constipation and social problems. With advancing age, the total BFS of HD patients improved, with a tendency close to the normal level beyond 10 years old. But, after grouped according to presence or absence of HAEC, the non-HAEC group experienced more dramatic improvement with age increasing.

CONCLUSIONS

Compared with matched peers, significant impairment of fecal control prevails after TRM-PIAS in HD patients, but bowel function improve with age and recovery faster than conventional procedure. It should be emphasized that post-enterocolitis is a high-risk factor for delayed recovery.

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.

Plasma single-stranded DNA autoantibodies in the diagnosis of Hirschsprung’s disease

Background

Hirschsprung’s disease (HSCR) is a neonatal enteric nervous system (ENS) disease characterized by congenital enteric ganglion cell loss. The only treatment is aganglionic bowel segment resection and innervated bowel segment reconstruction. Delayed diagnosis and treatment cause postoperative complications such as intractable constipation and enterocolitis. Existing preoperative HSCR diagnostic methods have shortcomings such as false positives, radiation and invasiveness.

Methods

We used the robust linear model (RLM) for normalization and the M statistic for screening plasma human autoimmune antigen microarrays and quantitatively assessed single-stranded DNA (ssDNA) antibody levels with enzyme-linked immunosorbent assay (ELISA).

Results

The autoimmune antigen microarray revealed that autoantibodies were higher in HSCR plasma than in disease control (DC) and healthy control (HC) plasma. ssDNA antibodies in HSCR plasma were significantly higher than those in DC and HC plasma. Quantitative ssDNA antibody level detection in plasma by ELISA showed that HSCR (n = 32) was 1.3- and 1.7-fold higher than DC (n = 14) and HC (n = 25), respectively. ssDNA antibodies distinguished HSCR from non-HSCR (HC and DC), achieving an area under the curve (AUC) of 0.917 (95% CI, 0.8550–0.9784), with a sensitivity of 96.99% and a specificity of 74.63%.

Conclusion

ssDNA antibodies in plasma can serve as a diagnostic biomarker for HSCR in the clinic.

Opportunities for novel diagnostic and cell-based therapies for Hirschsprung disease

Despite significant progress in our understanding of the etiology and pathophysiology of Hirschsprung disease (HSCR), early and accurate diagnosis and operative management can be challenging. Moreover, long-term morbidity following surgery, including fecal incontinence, constipation, and Hirschsprung-associated enterocolitis (HAEC), remains problematic. Recent advances applying state-of-the art imaging for visualization of the enteric nervous system and utilizing neuronal stem cells to replace the missing enteric neurons and glial cells offer the possibility of a promising new future for patients with HSCR. In this review, we summarize recent research advances that may one day offer novel approaches for the diagnosis and management of this disease.

A Novel Method for Identifying the Transition Zone in Long-Segment Hirschsprung Disease: Investigating the Muscle Unit to Ganglion Ratio

Hirschsprung disease (HSCR) is characterised by the absence of enteric ganglia along variable lengths of the distal bowel. Current gold standard treatment involves the surgical resection of the defective, aganglionic bowel. Clear and reliable distinction of the normoganglionated bowel from the transition zone is key for successful resection of the entire defective bowel, and the avoidance of subsequent postoperative complications. However, the intraoperative nature of the tissue analysis and the variability of patient samples, sample preparation, and operator objectivity, make reproducible identification of the transition zone difficult. Here, we have described a novel method for using muscle units as a distinctive landmark for quantifying the density of enteric ganglia in resection specimens from HSCR patients. We show that the muscle unit to ganglion ratio is greater in the transition zone when compared with the proximal, normoganglionated region for long-segment HSCR patients. Patients with short-segment HSCR were also investigated, however, the muscle unit to ganglion ratio was not significantly different in these patients. Immunohistochemical examination of individual ganglia showed that there were no differences in the proportions of either enteric neurons or glial cells through the different regions of the resected colon. In addition, we identified that the size of enteric ganglia was smaller for patients that went on to develop HSCR associated enterocolitis; although the density of ganglia, as determined by the muscle unit to ganglia ratio, was not different when compared with patients that had no further complications. This suggests that subtle changes in the enteric nervous system, even in the “normoganglionated” colon, could be involved in changes in immune function and subsequent bacterial dysbiosis.

Inpatient Care Utilization and Epidemiology of Hirschsprung Disease: Analysis of the National Inpatient Sample

BACKGROUND/OBJECTIVES

Hirschsprung disease (HD) is associated with significant morbidities including long-term bowel dysfunction. The aim of this study was to update national and regional trends in the inpatient care utilization and epidemiology of HD in the United States between 2009 and 2014 using the National Inpatient Sample (NIS) database.

METHODS

We identified all pediatric admissions with a diagnosis of HD within the NIS from 2009 through 2014. We analyzed HD discharges with respect to various demographic and clinical factors, specifically trends and group differences in inflation-adjusted cost of hospitalization, procedures, co-morbidities, hospital mortality, and length of stay (LOS). A modified Cochrane-Armitage trend test was used to analyze trends for dichotomous outcome variables, and regression analyses were conducted for continuous and binary variables.

RESULTS

National estimates of HD-discharges showed no significant trend between 2009 and 2014 ( P = 0.27), with estimated relative incidence ranging from 46 to 70 per 100,000 pediatric discharges. Inflation-adjusted cost of hospitalization increased by $1137 (SE $326) per year ( P = 0.0005). Pull-through procedures in neonatal age group increased from 33.0% in 2009 to 36.5% in 2014 ( P = 0.003). Hospital mortality has remained stable between 0.4% and 1.0% ( P = 0.598). LOS decreased by 0.23 days per year ( P = 0.036).

CONCLUSION

Increasing cost of HD-related hospitalization despite decreasing LOS was observed in this cohort. Stable rate of hospitalizations with increasing proportions of pull-through procedures among neonates was noted. Future studies and development of protocols to standardize patient care could improve outcomes and healthcare spending.

Generic and disease-specific health-related quality of life in patients with Hirschsprung disease: A systematic review and meta-analysis

BACKGROUND

Patients with Hirschsprung disease (HD) are at risk of persistent constipation, fecal incontinence or recurrent enterocolitis after surgical treatment, which in turn may impact physical and psychosocial functioning. Generic health-related quality of life (HRQoL) and disease-specific health-related quality of life are relevant outcome measures to assess the impact of HD on the QoL of these patients.

AIM

To summarize all available evidence on HRQoL of patients with HD after surgery and the impact of possible moderating factors.

METHODS

Pubmed, Web of Sciences, PsycInfo and Embase were searched with search terms related to ‘Hirschsprung disease’, ‘Pediatrics’ and ‘Quality of life’. Mean and standard deviation of generic HRQoL overall and domain scores were extracted from each study, as well as data describing potential factors associated with QoL. Random effect models were used for meta-analytic aggregation of generic HRQoL scores. Meta-regression was used to assess the relationship between patient and clinical characteristics and generic HRQoL. Disease-specific HRQoL outcomes of patients with HD were systematically reviewed.

RESULTS

Seventeen articles were included in the systematic review (n = 1137 patients) and 15 in the quantitative meta-analysis (n = 1024 patients). Four studies reported disease-specific HRQoL. Patient’s age ranged between 0 and 21 years. Meta-analytic aggregation showed a non-significantly impaired generic HRQoL (d = -0.168 [95%CI: -0.481; 0.145], P = 0.293, I² = 94.9) in patients with HD compared to healthy controls. Physical (d = -0.042 [95%CI: -0.419; 0.335], P = 0.829, I² = 95.1), psychosocial (d = -0.159 [95%CI: -0.458; 0.141], P = 0.299, I² = 93.6) and social HRQoL (d = -0.092 [95%CI: -0.642; 0.457], P = 0.742, I² = 92.3) were also not significantly lower compared to healthy controls. There was no relation between health-related outcomes and the sex of the patients and whether generic HRQoL was measured by parental proxy or self-report. Disease-specific complaints of patients with HD impaired physical HRQoL, but not psychosocial and social HRQoL.

CONCLUSION

In this systematic review and meta-analysis, no evidence was found for impaired generic HRQoL in patients with HD compared to healthy controls, neither for moderating effects of sex, parental proxy or self-report.

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.

Optimal timing for Soave primary pull-through in short-segment Hirschsprung disease: A meta-analysis

BACKGROUND

The optimal age for endorectal pull-through (ERPT) surgery in infants with short-segment Hirschsprung disease varies, with a trend toward earlier surgery. However, it is unclear if the timing of surgery impacts functional outcomes. We undertook the present study to determine the optimal timing of ERPT in infants with short-segment Hirschsprung disease.

METHODS

The NCBI PubMed database was searched for English-language manuscripts published between 2000 and 2019 analyzing functional outcomes for patient following the initial Soave ERPT for short-segment Hirschsprung disease. Raw data from these studies was obtained from the corresponding author for each manuscript. We combined data from these papers with our own institutional data and performed a meta-analysis.

RESULTS

A total of 780 infants were included in our meta-analysis. Constipation occurred in 1.0-31.7%, soiling 1.3-26.0%, anastomotic stricture 0.0-14.6%, and anastomotic leak 0.0-3.4%. Regarding age at ERPT, younger infants at the time of initial corrective surgery had higher rates of soiling, stricture, and leak. On sub-group analysis, patients <2.5 months at their initial corrective surgery had higher rates of soiling (25.9% vs. 11.4%, p<0.01), as well as stricture (10.0% vs 1.7%, p<0.01) and leak (5.5% vs 1.3%, p<0.01).

CONCLUSION

While age at Soave endorectal pull-through for short-segment Hirschsprung disease has decreased over time, functional outcomes associated with this trend have only recently been examined. Our findings suggest that patients <2.5 months old at the time of endorectal pull-through may have worse functional outcomes, emphasizing the need to consider further study of the timing of surgery in this population.

Functional Outcomes After Surgery for Total Colonic, Long-Segment, Versus Rectosigmoid Segment Hirschsprung Disease

OBJECTIVES

Knowledge on long-term outcomes in patients with Hirschsprung disease is progressing. Nevertheless, differences in outcomes according to aganglionic lengths are unclear. We compared long-term bowel function and generic quality of life in Hirschsprung patients with total colonic or long-segment versus rectosigmoid aganglionosis.

METHODS

In this nationwide, cross-sectional study participants with proven Hirschsprung disease received the Defecation and Fecal Continence questionnaire, and the Child Health Questionnaire Child Form-87, or the WHO Quality of Life-100. We excluded deceased patients, patients who were younger than 8 years, lived abroad, had a permanent enterostomy, or were intellectually impaired.

RESULTS

The study population (n = 334) was operated for rectosigmoid (83.9%), long-segment (8.7%), or total colonic aganglionosis (7.5%). Fecal incontinence in general was not significantly different between the three groups, but liquid fecal incontinence was significantly associated with total colonic aganglionosis (odds ratio [OR] = 6.00, 95% confidence interval [CI] 2.07-17.38, P = 0.001). Regarding constipation, patients with total colonic or long-segment aganglionosis were less likely to suffer from constipation than the rectosigmoid group (OR = 0.21, 95% CI, 0.05-0.91, P = 0.038 and OR = 0.11, 95% CI, 0.01-0.83, P = 0.032). Quality of life was comparable between the three groups, except for a lower physical score in children with total colonic aganglionosis (P = 0.016).

CONCLUSIONS

Over time Hirschsprung patients with total colonic or long-segment aganglionosis do not suffer from worse fecal incontinence in general. A difference in stool consistency may underlie the association between liquid fecal incontinence and total colonic aganglionosis and constipation in patients with rectosigmoid aganglionosis. Despite these differences, generic quality of life is comparable on reaching adulthood.

Psychosocial factors affecting quality of life in patients with anorectal malformation and Hirschsprung disease-a qualitative systematic review

INTRODUCTION

Little is known about psychosocial and behavioral factors that impact the quality of life of patient's with anorectal malformations (ARM) and Hirschsprung disease (HSCR). We aimed to highlight the psychosocial, emotional, and behavioral themes that affect these patients.

METHODS

A qualitative literature review of articles published between 1980 and 2019 was performed. Articles that reported quality of life (QoL) measures not directly related to bowel function and incorporated data on patients aged 0-21 years old were included. Data were separated based on distinct developmental time points.

RESULTS

In the neonatal period, parents relayed uncertainty about the future and feeling overwhelmed by lack of social support. Difficulties with anxiety, peer rejection, and behavioral problems were noted in primary grades, while adolescents experienced low self-confidence, poor body image, and depression. Young adults expressed hesitancy to engage in romantic relationships or sexual activity. Lack of long-term follow-up, an incomplete transition to adult healthcare, and lack of psychology services leave young adults without guidance to manage a chronic condition.

CONCLUSION

Multiple psychosocial stressors are present in the lives of ARM and HSCR patients. Provision of developmentally matched medical, psychological, and community-based supports for ARM and HSCR patients and their families can lead to improved QoL.

Comparison of clinical features and prognosis between ultrashort-segment and short-segment hirschsprung disease

OBJECTIVE

To compare the differences in clinical features, postoperative complications, and long-term bowel function outcomes of ultrashort-segment Hirschsprung disease (USHD) and short-segment Hirschsprung disease (SHD).

METHODS

A retrospective study was conducted to compare patients with USHD or SHD who underwent transanal endorectal pull-through (TEPT) at Beijing Children's Hospital between January 2014 and June 2021. Clinical details were collected from medical records. A long-term bowel function questionnaire (age > 4 years old) was completed by the patients' parents.

RESULTS

A total of 84 patients (USHD = 15, SHD = 69) were included. Age at diagnosis and radical surgery in the USHD group were significantly older than the SHD group (46 [38, 66] vs. 34 [6, 55] months, p = 0.002; 51 [39, 68] vs. 37 [10, 68] months, p = 0.001, respectively). Compared with the SHD group, patients with USHD are more likely to suffer anastomosis leakage and postoperative enterocolitis after TEPT ([3/15, 33.3%] vs. [1/69, 1.4%], p = 0.017; [5/15, 33.3%] vs. [6/69, 8.7%], p = 0.023). In addition, patients in the USHD group are inclined to suffer lower bowel function scores (12.0 [7.5, 18.3] vs. 17 [15, 19], p = 0.018).Patients in the USHD group were more likely to suffer poorer ability to hold back defecation (p = 0.023), soiling (p = 0.011), fecal accidents (p = 0.004), and social problems (p = 0.004).

CONCLUSION

Compared with patients with SHD, patients with USHD are diagnosed and performed TEPT at an older age. and they are inclined to suffer postoperative enterocolitis, anastomosis leakage, and poorer long-term bowel function following TEPT.

Familial Experience With Hirschsprung's Disease Improves the Patient's Ability to Cope

INTRODUCTION

Familial occurrence of Hirschsprung's disease may have a positive effect on patients' ability to cope with the disease. The aim was to compare long-term bowel function and generic quality of life between patients with familial and non-familial Hirschsprung's disease.

METHODS

This was a nationwide, cross-sectional study in which we included all 830 Hirschsprung patients of 8 years and older who had undergone surgery between 1957 and 2015. We excluded patients with a permanent stoma, intellectual disability, or an unknown or foreign address. We requested patients to complete the validated pediatric or adult Defecation and Fecal Continence questionnaire and the Child Health Questionnaire Child Form-87, or the World Health Organization Quality of Life-100 Assessment Instrument.

RESULTS

We analyzed 336 Hirschsprung patients, 15.8% of whom were familial cases and 84.2% were non-familial cases. After adjusting for aganglionic length, sex, and age, patients with familial Hirschsprung's disease were twice more likely to suffer from constipation (OR = 2.47, 95% CI, 1.21-5.05, p = 0.013). The quality of life of the pediatric patients was comparable, but in adult patients the energy/fatigue, thinking/learning/concentration, and work capacity facets showed better scores in the familial patients with Hirschsprung's disease of the rectosigmoid (p = 0.029, p = 0.024, p = 0.036, respectively).

CONCLUSIONS

Different facets of generic quality of life are better in adult patients with familial Hirschsprung's disease of the rectosigmoid. It seems that familial experience with the disease influences patients' coping abilities positively.

Children with congenital colorectal malformations during the UK Sars-CoV-2 pandemic lockdown: an assessment of telemedicine and impact on health

PURPOSE

This pilot study was designed to assess bowel function and quality of life (QoL) in children and adolescents with congenital colorectal malformations (CCM) during the first UK COVID lockdown period.

METHODS

Changes in health were assessed through semi-structured interviews, gastrointestinal functional outcomes using Krickenbeck scoring and QoL by the modified disease-specific HAQL (Hirschsprung's disease anorectal malformation quality of life questionnaire). The State-Trait Anxiety Inventory (STAI)™ for adults was used to assess parental anxiety.

RESULTS

Thirty-two families were interviewed; 19 (59%) reported no change in their child's health during the lockdown, 5 (16%) a deterioration and 8 (25%) an improvement. Neither the severity of the CCM, nor the degree of bowel dysfunction, correlated with any deterioration. The HAQL score was not correlated to a change in health. Anxiety scores ranged from no anxiety to clinical concerns. Telemedicine was well accepted by 28/32 parents (88%); however, in-person appointments were preferred if there were clinical concerns.

CONCLUSION

In the follow-up of children and adolescents with CCM during the first UK lockdown using telemedicine we found that over half had stable health conditions. Patients needing additional care could not be predicted by the severity of their disease or their bowel function alone.

Assessment of defecation function beyond infantile period for transanal single-stage endorectal pull-through in Hirschsprung disease

Purpose

Transanal single-stage endorectal pull-through (TERPT) procedure for patients with Hirschsprung disease (HD) has favorable outcomes, with a lower complication rate. Nevertheless, various degrees of bowel dysfunction and fecal incontinence can persist for a long time in some patients. The aim of this study was to assess the mid- and long-term outcomes of TERPT performed during the infantile period after the completion of toilet training.

Methods

We retrospectively reviewed 82 patients aged ≥4 years who underwent TERPT during the infantile period after the pathological diagnosis of HD between 2001 and 2013. Functional outcomes were investigated according to the answers of the Bowel Function Score (BFS) questionnaire, a previously validated 7-item questionnaire about bowel habits. Normal values were obtained in a previous study on BFS for children in Western countries, and a one-sample t-test was used for statistical analysis.

Results

Overall, BFS was similar in all investigated age groups. On comparing fecal soiling and social problems between the HD and normal populations, a lower score at an early age in patients with HD was noted; however, the scores became similar when the patients were 7 years of age. Stool frequency decreased continuously but was not significantly different between the 2 groups.

Conclusion

The functional outcomes of TERPT performed during the infantile period, after completing toilet training, were similar to that of the normal population. In most cases, uncomfortable symptoms were diminished and functions improved with age.

Management and outcomes for long-segment Hirschsprung disease: A systematic review from the APSA Outcomes and Evidence Based Practice Committee

OBJECTIVE

Long-Segment Hirschsprung Disease (LSHD) differs clinically from short-segment disease. This review article critically appraises current literature on the definition, management, outcomes, and novel therapies for patients with LSHD.

METHODS

Four questions regarding the definition, management, and outcomes of patients with LSHD were generated. English-language articles published between 1990 and 2018 were compiled by searching PubMed, Scopus, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar. A qualitative synthesis was performed.

RESULTS

66 manuscripts were included in this systematic review. Standardized nomenclature and preoperative evaluation for LSHD are recommended. Insufficient evidence exists to recommend a single method for the surgical repair of LSHD. Patients with LSHD may have increased long-term gastrointestinal symptoms, including Hirschsprung-associated enterocolitis (HAEC), but have a quality of life similar to matched controls. There are few surgical technical innovations focused on this disorder.

CONCLUSIONS

A standardized definition of LSHD is recommended that emphasizes the precise anatomic location of aganglionosis. Prospective studies comparing operative options and long-term outcomes are needed. Translational approaches, such as stem cell therapy, may be promising in the future for the treatment of long-segment Hirschsprung disease.

Long-term surgical and patient-reported outcomes of Hirschsprung Disease

BACKGROUND

Information is needed regarding the complex relationships between long-term functional outcomes and health-related quality of life (HRQoL) in Hirschsprung's Disease (HSCR). We describe long-term outcomes across multiple domains, completing a core outcome set through to adulthood.

METHODS

HSCR patients operated at a single center over a 35-year period (1978-2013) were studied. Patients completed detailed questionnaires on bowel and urologic function, and HRQOL. Patients with learning disability (LD) were excluded. Outcomes were compared to normative data. Data are reported as median [IQR] or mean (SD).

RESULTS

186 patients (median age 28 [18-32] years; 135 males) completed surveys. Bowel function was reduced (BFS 17 [14-19] vs. 19 [19-20], p < 0•0001;η² = 0•22). Prevalence and severity of fecal soiling and fecal awareness improved with age (p < 0•05 for both). Urinary incontinence was more frequent than controls, most of all in 13-26y females (65% vs. 31%,p = 0•003). In adults, this correlated independently with constipation symptoms (OR 3.18 [1.4-7.5],p = 0.008). HRQoL outcomes strongly correlated with functional outcome: 42% of children demonstrated clinically significant reductions in overall PedsQL score, and poor bowel outcome was strongly associated with impaired QOL (B = 22•7 [12•7-32•7],p < 0•001). In adults, GIQLI scores were more often impacted in patients with extended segment disease. SF-36 scores were reduced relative to population level data in most domains, with large effect sizes noted for females in General Health (g = 1.19) and Social Wellbeing (g = 0.8).

CONCLUSION

Functional impairment is common after pull-through, but bowel function improves with age. Clustering of poor functional outcomes across multiple domains identifies a need for early recognition and long-term support for these patients.

Perioperative and long-term functional outcomes of neonatal versus delayed primary endorectal pull-through for children with Hirschsprung disease: A pediatric colorectal and pelvic learning consortium study

BACKGROUND/PURPOSE

the timing of endorectal pull-through for Hirschsprung disease (HD) is controversial. Neonatal primary endorectal pull-through theoretically prevents preoperative enterocolitis. Delayed primary endorectal pull-through offers the surgeon the benefit of more robust perineal anatomy and allows primary caregivers the time to emotionally process the diagnosis and to gain experience with rectal irrigations. We hypothesized that delayed primary endorectal pull-through would be associated with equivalent perioperative morbidity compared to the neonatal repair and would lead to improved long-term functional outcomes.

METHODS

we analyzed all patients in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) registry who had a primary endorectal pull-through for HD and at least three-and-one-half years of follow up in a specialty colorectal clinic. We evaluated patient demographics, operative outcomes, perioperative episodes of enterocolitis, and long-term functional outcomes for the neonatal (<31 days) and delayed (≥31 days) pull-through cohorts.

RESULTS

eighty-two patients were identified of whom 49 were operated upon in the neonatal period and 33 in a delayed fashion. The median age at operation was 11 days [IQR 7 - 19 days] for the neonatal cohort and 98 days [IQR 61 - 188 days] for the delayed cohort. Thirty-four (69.4%) of the neonatal and 22 (66.7%) of the delayed cohort patients had rectosigmoid transition zones. Four of 49 patients (8.1%) in the neonatal cohort were diagnosed with enterocolitis preoperatively compared to two of 33 (6.0%) in the delayed cohort (p = 0.89). Eighteen of 49 patients (36.7%) in the neonatal cohort and 16 of 33 (48.5%) in the delayed cohort had at least one postoperative episode of enterocolitis (p = 0.38). Fifteen of 49 patients (30.6%) in the neonatal cohort were receiving bowel management for fecal incontinence at most recent follow up compared to five of 33 (15.2%) in the delayed cohort (p = 0.13).

CONCLUSION

delayed primary endorectal pull-through offers a safe alternative to operation in the neonatal period and appears to have, at least, equivalent functional outcomes.
