Abstract
BACKGROUND Despite identifying numerous risk factors for postoperative Hirschsprung-associated enterocolitis (HAEC), predicting individual risk remains challenging. This study aimed to develop a clinical prediction model for predicting the probability of postoperative HAEC within 5 years after surgery in Hirschsprung individuals. METHODS The study included all children with Hirschsprung disease who underwent definitive surgery at Chiang Mai University Hospital from 2006 to 2021. Concomitant anorectal abnormalities and incomplete data were excluded. A multivariable logistic regression analysis, adjusted for correlated data, was utilized to develop the prediction model. RESULTS Of the included 274 patients, 75 patients (27.4%) experienced postoperative HAEC within 5 years, totaling 121 episodes. Based on statistical and theoretical significance, eight parameters were utilized as predictors, which included male (OR1.23,95%CI:0.53-2.86), trisomy21(OR1.34,95%CI:0.21-8.45), weight at the time of surgery (OR0.86,95%CI:0.73-1.02), absence of exclusive breastfeeding (OR1.51,95%CI:0.65-3.51), length of the aganglionic segment (rectosigmoid (OR1.32,95%CI:0.48-3.62), long segment (OR41.39,95%CI:3.00-570.37), and total colonic aganglionosis (OR710.20,95%CI:23.55-21420.72)), preoperative stoma (OR1.72,95%CI:0.34-8.58), surgical approach (Duhamel (OR0.06,95%CI:0.01-0.81) and abdominal assisted trans anal endorectal pull-through (OR0.04,95%CI:0.002-0.65)), and early HAEC before two weeks following surgery (OR1.98,95%CI:0.67-5.82). The derived predictive model exhibited acceptable discriminative performance (AuROC:0.749,95%CI:0.679-0.816). Risk groups were categorized into low and high-risk, with positive likelihood ratios of 0.65 and 10.70, respectively. Recommendations for management and follow-up were generated based on these risk groups. An online application has been developed for calculating individual risk of postoperative HAEC and offering management suggestions with follow-up schedule: [https://w1.med.cmu.ac.th/surgery/personnel/pedsurgerycmu/#HAEC-Calculator]. CONCLUSIONS This risk predictive model accurately estimates the probability of postoperative HAEC within 5 years after surgery in Hirschsprung patients. It facilitates risk stratification and provides personalized recommendations to parents for the prevention and early detection of postoperative HAEC.

Abstract
BACKGROUND Children with total colonic Hirschsprung disease (TCHD) are a unique group of patients with pre- and postoperative management challenges. This review provides a rational, expert-based approach to diagnosing and managing TCHD. METHODS The guidelines were developed by the Hirschsprung Disease Interest Group members established by the American Pediatric Surgical Association (APSA) Board of Governors. Group discussions, literature review, and expert consensus were used to summarize the current knowledge regarding diagnosis, staged approach, the timing of pull-through, and pre-and postoperative management in children with TCHD. RESULTS This paper presents recommendations for managing TCHD before and after reconstruction, including diagnostic criteria, surgical approaches, bowel management, diet, antibiotic prophylaxis, colonic irrigations, and post-surgical considerations. CONCLUSIONS A clear understanding of the unique challenges posed by TCHD and consensus on its treatment are lacking in the literature. This review standardizes this patient group's pre- and postoperative management. LEVEL OF EVIDENCE V.

LA PEDIATRIA MEDICA E CHIRURGICA 2024; 46. [PMID: 38963345 DOI: 10.4081/pmc.2024.333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 04/09/2024] [Indexed: 07/05/2024] Open
Abstract
The main advantage of the laparo-assisted transanal endorectal pull-through technique (LA - TERPT) for Hirschsprung Disease (HD) is the respect to the rectal-anal anatomy. Postoperative complications have been observed recently. The present study aims to determine how often these postoperative complications occur in these patients. From January 2009 to December 2018, a retrospective analysis was conducted on 36 children (25 males) with HD who underwent LA-TERPT. Data were collected on the age of diagnosis and surgery, sex, the presence of other pathologies, and cases of enterocolitis. In all cases, anorectal manometry (ARM) was performed to evaluate the anal tone. The median age at diagnosis was 2 months and the mean age at surgery was 5 months. Nine related pathologies were identified: five cases of Down syndrome, one case of hypertrophic stenosis of the pylorus, atresia of the esophagus, polydactyly, and anorectal malformation. A patient with total colonic aganglionosis was identified through laparoscopic serummuscular biopsies. Enterocolitis was diagnosed in 7 cases before and 6 after surgery. At follow-up, the complications recorded were: 5 cases of constipation (treated with fecal softeners), one case of anal stenosis (patient with anorectal malformation), 16 cases of soiling (treated with enemas) and 1 child with fecal incontinence (treated with a transanal irrigation system). The ARM was performed in all 36 cases and showed normal anal tone, except for one case with anal hypotonia. LA-TERPT is an important surgical technique for HD. According to the literature, soiling is the most main complication after HD surgery, probably due to "pseudo-incontinence" with normal anal sphincter tone.

Abstract
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.

Abstract
BACKGROUND The incidence of Hirschsprung disease (HSCR) is nearly 1/5000 and patients with HSCR are usually treated through surgical intervention. Hirschsprung disease-associated enterocolitis (HAEC) is a complication of HSCR with the highest morbidity and mortality in patients. The evidence on the risk factors for HAEC remains inconclusive to date. METHODS Four English databases and four Chinese databases were searched for relevant studies published until May 2022. The search retrieved 53 relevant studies. The retrieved studies were scored on the Newcastle-Ottawa Scale by three researchers. Revman 5.4 software was employed for data synthesis and analysis. Stata 16 software was employed for sensitivity analysis and bias analysis. RESULTS A total of 53 articles were retrieved from the database search, which included 10 012 cases of HSCR and 2310 cases of HAEC. The systematic analysis revealed anastomotic stenosis or fistula [ I2 =66%, risk ratio (RR)=1.90, 95% CI 1.34-2.68, P <0.001], preoperative enterocolitis ( I2 =55%, RR=2.07, 95% CI 1.71-2.51, P <0.001), preoperative malnutrition ( I2 =0%, RR=1.96, 95% CI 1.52-2.53, P <0.001), preoperative respiratory infection or pneumonia ( I2 =0%, RR=2.37, 95% CI 1.91-2.93, P <0.001), postoperative ileus ( I2 =17%, RR=2.41, 95% CI 2.02-2.87, P <0.001), length of ganglionless segment greater than 30 cm ( I2 =0%, RR=3.64, 95% CI 2.43-5.48, P <0.001), preoperative hypoproteinemia ( I2 =0%, RR=1.91, 95% CI 1.44-2.54, P <0.001), and Down syndrome ( I2 =29%, RR=1.65, 95% CI 1.32-2.07, P <0.001) as the risk factors for postoperative HAEC. Short-segment HSCR ( I2 =46%, RR=0.62, 95% CI 0.54-0.71, P <0.001) and transanal operation ( I2 =78%, RR=0.56, 95% CI 0.33-0.96, P =0.03) were revealed as the protective factors against postoperative HAEC. Preoperative malnutrition ( I2 =35 % , RR=5.33, 95% CI 2.68-10.60, P <0.001), preoperative hypoproteinemia ( I2 =20%, RR=4.17, 95% CI 1.91-9.12, P <0.001), preoperative enterocolitis ( I2 =45%, RR=3.51, 95% CI 2.54-4.84, P <0.001), and preoperative respiratory infection or pneumonia ( I2 =0%, RR=7.20, 95% CI 4.00-12.94, P <0.001) were revealed as the risk factors for recurrent HAEC, while short-segment HSCR ( I2 =0%, RR=0.40, 95% CI 0.21-0.76, P =0.005) was revealed as a protective factor against recurrent HAEC. CONCLUSION The present review delineated the multiple risk factors for HAEC, which could assist in preventing the development of HAEC.

Abstract
Hirschsprung's disease (HSCR) is a congenital disorder characterized by failure of the neural crest cells to migrate and populate the distal bowel during gestation affecting different lengths of intestine leading to a distal functional obstruction. Surgical treatment is needed to correct HSCR once the diagnosis is confirmed by demonstrating the absence of ganglion cells or aganglionosis of the affected bowel segment. Hirschsprung's disease associated enterocolitis (HAEC) is an inflammatory complication associated with HSCR that can present either in the pre- or postoperative period and associated with increased morbidity and mortality. The pathogenesis of HAEC remains poorly understood, but intestinal dysmotility, dysbiosis and impaired mucosal defense and intestinal barrier function appear to play a significant role. There is no clear definition for HAEC, but the diagnosis is primarily clinical, and treatment is guided based on severity. Here, we aim to provide a comprehensive review of the clinical presentation, etiology, pathophysiology, and current therapeutic options for HAEC.

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

Abstract
BACKGROUND In patients with Hirschsprung disease (HSCR), soiling may be related to anal sphincter damage following the initial pull-through. No optimal treatment has been developed for such patients, although enemas (rectal or antegrade) have been applied with some success. We present the one-year outcomes of a new technique for anal sphincter reconstruction. METHODS All patients with HSCR referred from other institutions for post pull-through soiling were studied. Seven patients with patulous sphincters underwent sphincter reconstruction. Six had a full preoperative evaluation and were included in the study. Their 12-month outcomes were assessed. RESULTS All six patients had soiling without voluntary bowel movements (VBMs). One patient was clean on Malone flushes when referred. Three underwent pre- and post-reconstruction non-sedated three-dimensional anorectal manometry, and objectively were able to close their sphincters following the reconstruction. All patients without Down syndrome (4 of 6) showed improvement in the abbreviated Baylor Continence Scale (4.5 vs. 0.75). One patient has achieved total bowel control without antegrade flushes, three now have VBMs which they did not have before but have occasional accidents and use antegrade flushes intermittently. They reported higher productivity, the ability to participate in sports and be away from home with confidence in their regimen. Two of 6 patients have Down syndrome and required a redo pull-through for other indications and underwent empiric sphincter reconstruction. For these two patients we do not have an outcomes assessment. CONCLUSIONS A new technique for sphincter reconstruction shows promising results in improvement of bowel control at one year.

Abstract
PURPOSE To identify prognostic factors of postoperative Hirschsprung-associated enterocolitis (HAEC). METHOD A retrospective cohort study of Hirschsprung patients between 2006 and 2021 was conducted. Patients with anorectal malformation and non-definitive surgery were excluded. Associated factors for postoperative HAEC were reported with hazard ratio (HR) and 95% confidence interval (CI). RESULTS Forty-nine patients were excluded due to concurrent anorectal malformation and incomplete data. Of 274 patients, 75 patients (27.4%) had at least one episode of postoperative HAEC. There were 28 patients (37.3%) who had multi-episodes of HAEC. The total episodes of post-operative HAEC in this study were 121 episodes (36.8%). In multivariable survival analysis, significant factors associated with postoperative HAEC were the aganglionic level above sigmoid colon (HR = 3.47, p = 0.023, 95% CI 1.19-10.09), and total colonic aganglionosis (HR = 14.83, p = 0.004, 95% CI 2.33-94.40). The patients who experienced clinical enterocolitis before 2 weeks after surgery significantly developed more postoperative HAEC (HR = 5.32, p = 0.038, % CI 1.09-25.92). The incidence of postoperative HAEC was increase in patients with postoperative obstructive symptoms (48.0%). One patient died due to severe sepsis from postoperative HAEC, while three others required intensive care. CONCLUSIONS The long involvement of aganglionic segment and early postoperative HAEC was significantly associated with postoperative HAEC. Frequent follow-up, parental education, and early treatment are recommended in these individuals, particularly in the first year after surgery.

Abstract
PURPOSE Hirschsprung disease is a neurointestinal disease that occurs due to failure of enteric neural crest-derived cells to complete their rostrocaudal migration along the gut mesenchyme, resulting in aganglionosis along variable lengths of the distal bowel. Despite the effective surgery that removes the aganglionic segment, children with Hirschsprung disease remain at high risk for developing a potentially life-threatening enterocolitis (Hirschsprung-associated enterocolitis). Although the etiology of this enterocolitis remains poorly understood, several recent studies in both mouse models and in human subjects suggest potential involvement of gastrointestinal microbiota in the underlying pathogenesis of Hirschsprung-associated enterocolitis. METHODS We present the first study to exploit the Illumina MiSeq next-generation sequencing platform within a longitudinal framework focused on microbiomes of Hirschsprung-associated enterocolitis in five patients. We analyzed bacterial communities from fecal samples collected at different timepoints starting from active enterocolitis and progressing into remission. RESULTS We observed compositional differences between patients largely attributable to variability in age at the time of sample collection. Remission samples across patients exhibited compositional similarity, including enrichment of Blautia, while active enterocolitis samples showed substantial variability in composition. CONCLUSIONS Overall, our findings provide continued support for the role of GI microbiota in the pathogenesis of Hirschsprung-associated enterocolitis.

Abstract
Abstract
Background
Congenital gastrointestinal malformation (CGIM) require neonatal surgical treatment and may lead to disease-specific sequelae, which have a potential psychological impact on parents. The aim of this study is to assess distress and symptoms of post-traumatic stress disorder (PTSD) in parents of patients with CGIM. In this cross-sectional study, seventy-nine parents (47 mothers and 32 fathers) of 53 patients with CGIM completed the Distress Thermometer for Parents (DT-P) and the Self Rating Scale for Posttraumatic Stress Disorders (SRS-PTSD) as part of the multidisciplinary follow-up of their children (aged 5–35 months). Group differences were tested between parents and representative Dutch reference groups with regard to rates of (clinical) distress and PTSD, and severity of overall distress and PTSD, for mothers and fathers separately. Mixed model regression models were used to study factors associated with the risk of (clinical) distress, PTSD and with severity of symptoms of PTSD (intrusion, avoidance and hyperarousal).
Results
Prevalence of clinical distress was comparable to reference groups for mothers (46%) and fathers (34%). There was no difference in severity of overall distress between both mothers as well as fathers and reference groups. Prevalence of PTSD was significantly higher in mothers (23%) compared to the reference group (5.3%) (OR = 5.51, p < 0.001), not in fathers (6.3% vs 2.2.%). Symptoms of intrusion were commonly reported by all the parents (75%). Longer total length of child’s hospital stay was associated with more severe symptoms of intrusion, avoidance and hyperarousal. Child’s length of follow-up was negatively associated with severity of intrusion.
Conclusions
Having a child with CGIM has a huge impact on parents, demonstrated by a higher prevalence of PTSD in mothers, but not fathers, compared to parents in the general population. Monitoring of symptoms of PTSD of parents in follow-up is necessary.

Routine botulinum toxin injection one month after a Swenson pull-through does not change the incidence of Hirschsprung associated enterocolitis. J Pediatr Surg 2022; 57:1453-1457. [PMID: 34991869 DOI: 10.1016/j.jpedsurg.2021.11.029] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 10/21/2021] [Accepted: 11/11/2021] [Indexed: 12/01/2022]
Abstract
PURPOSE Patients with Hirschsprung disease (HD) are at risk of Hirschsprung associated enterocolitis (HAEC) following pull-through. The purpose of this study was to determine if routine Botulinum toxin (BT) injected one-month post pull-through decreases the incidence of HAEC. METHODS We reviewed patients who underwent a primary (not redo) pull-through operation for HD between April 2014 to December 2019. Over the most recent 18 months, BT was administered routinely one-month post-pull-through procedure; these patients were compared to the prior group that did not receive routine BT. A HAEC episode was defined as one that required initiation of treatment for obstructive symptoms in the inpatient or outpatient setting with antibiotics and irrigations. Categorical variables were compared using the nonparametric chi-square test or Fisher's exact test. Continuous variables were compared using the two-tailed Student's t-test. P-value <0.05 was determined to be statistically significant. RESULTS A total of 70 patients underwent Swenson pull-through during the study period (52% male). There were no statistically significant differences in demographics in the BT vs. non-BT group. Routine post-pull-through BT was given in 28 patients and did not significantly change HAEC incidence compared to the non-BT group (12/28, 43% vs. 16/42, 38%. P = 0.691). Of note, the BT group patients developed HAEC significantly sooner than the patients in the non-BT group (37.5 days vs. 253 days, p = 0.029). More patients in the BT group (n = 18, 64%) required at least one subsequent BT injection compared to the patients in the non-BT group (n = 11, 26%. P = 0.001). CONCLUSIONS We conclude that routine postoperative botulinum toxin injection given one month postoperatively from Swenson pull-through did not change the incidence of HAEC. A prospective controlled study is necessary to confirm these findings.

Abstract
INTRODUCTION Hirschsprung's-associated enterocolitis (HAEC) is a common post-operative problem for patients with Hirschsprung disease (HSCR). However, treatment strategies remain variable among providers, institutions, and even nations. The purpose of this study was to identify differences in treatment patterns for HAEC. METHODS A questionnaire was distributed to members of the International Pediatric Endoscopic Group (IPEG) community that focused on HSCR and HAEC management strategies. Questionnaire responses were collected via the Research Electronic Data Capture (RedCap). RESULTS 178 responses were obtained: 30% from North America, 20% South America, 20% Europe, 26% Asia, and 4% from Australia. 37% had a dedicated pediatric colorectal center. After diagnosis, 53% send patients home with irrigations, while 29% perform a primary PT before discharge; the type of PT varied between Soave (50%), Swenson (25%) and Duhamel (13%). Only 29 respondents (17%) stated their institution had guidelines for HAEC management; however, inpatient treatments were fairly consistent: 95% performed rectal irrigations, 93% obtained an abdominal radiograph, and 72% held feeds; 55% taught families irrigations before discharge. Utilization of Botulinum (BT) injections was mixed: 36% never utilized BT injections, 33% only used BT if irrigations were not tolerated, and 16% only injected BT for recurrent episodes. Preventative HAEC measures were also varied and included anal dilations (44%), prophylactic antibiotics (34%), probiotics (29%), and routine home irrigations (22%). CONCLUSION There is wide variation of care in managing enterocolitis episodes in patients with Hirschsprung disease. Further research leading to consensus guidelines and standardization practices can help improve the care for these patients. LEVEL OF EVIDENCE V TYPE OF STUDY: Treatment study/ survey.

Abstract
PURPOSE Botulinum toxin (BT) is used to treat pediatric patients with Hirschsprung disease (HD) with obstructive symptoms. We aimed to characterize use of BT in HD patients across pediatric colorectal surgery referral centers. METHODS A multicenter retrospective study of BT use in children (0-18y) with HD was performed using the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) between 2017 and 2021. Sites with <10 HD patients recorded were excluded. Patterns were evaluated using Fisher's exact, Wilcoxon rank-sum, Kruskal-Wallis, and Cochran-Armitage trend test. RESULTS 494 patients at 8 centers were included. 118 (23.9%) received at least one BT injection. Among patients who required redo pullthrough procedures, 53.1% received BT compared to 22.7% of patients who only underwent one pullthrough (p<0.001). Age at pullthrough was also significantly associated (p = 0.021). A lower proportion of Hispanic patients received BT (9.6% vs. 26.3%;p = 0.006). Percentage of HD patients receiving BT varied significantly across sites (p<0.001). CONCLUSIONS Use of BT in patients with HD varies widely with greater use in patients who underwent redo surgery and in those who underwent pullthrough at an older age. Hispanic patients received less BT. These findings highlight the need to develop consensus guidelines and for further study on timing of injections and potential disparities in care.

Abstract
OBJECTIVES Total colonic aganglionosis involving the small bowel is a rare form of Hirschsprung disease. We aim to analyse the long-term outcomes, digestive autonomy, and complications, to suggest recommendations for prevention and treatment. METHODS All patients born between 2000 and 2015 followed in our centre were retrospectively included. We analysed the length of aganglionosis, surgical procedures, growth, duration of parenteral nutrition (PN), enterocolitis, liver disease, intestinal transplantation. RESULTS Twenty-five patients were followed for a median of 10.9 years. Fifteen patients had less than 80 cm of ganglionic small bowel (SB) with a median of 20 cm. Ten patients had more than 80 cm of ganglionic sB with a median of 115 cm. The median PN duration was significantly shorter for patients with more than 80 cm: 0.9 versus 7.5 years in those with less than 80 cm (P < 0.001). No patient with less than 80 cm was weaned off PN, except 1 who underwent intestinal transplantation. Ten patients with less than 80 cm develop enterocolitis on the excluded segment, leading to emergency entero-colectomy in 5. Liver disease was more frequent in patients with less than 80 cm (11 vs 0). Three patients required combined liver-intestine transplantation; 2 underwent an isolated intestinal transplantation. CONCLUSIONS Digestive autonomy was possible in most patients with more than 80 cm of ganglionic SB. The more severe complication was enterocolitis. Liver disease compromised long-term survival without transplantation. Both complications should be prevented by early diversion and enterectomy of the whole aganglionic segment. Follow-up in or together with a multidisciplinary intestinal rehabilitation centre is suggested.

Abstract
BACKGROUND Hirschsprung-associated enterocolitis (HAEC) is a leading cause of serious morbidity and potential mortality in children with Hirschsprung's disease (HD). People with HAEC suffer from intestinal inflammation, and present with diarrhoea, explosive stools, and abdominal distension. Probiotics are live microorganisms with beneficial health effects, which can optimise gastrointestinal function and gut flora. However, the efficacy and safety of probiotic supplementation in the prevention of HAEC remains unclear. OBJECTIVES To assess the effects of probiotic supplements used either alone or in combination with pharmacological interventions on the prevention of Hirschsprung-associated enterocolitis. SEARCH METHODS We searched CENTRAL, PubMed, Embase, the China BioMedical Literature database (CBM), the World Health Organization International Clinical Trials Registry, ClinicalTrials.gov, the Chinese Clinical Trials Registry, Australian New Zealand Clinical Trials Registry, and Clinical Trials Registry-India, from database inception to 27 February 2022. We also searched the reference lists of relevant articles and reviews for any additional trails. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing probiotics and placebo, or any other non-probiotic intervention, for the prevention of HAEC were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risk of bias of the included studies; disagreements were resolved by discussion with a third review author. We assessed the certainty of evidence using the GRADE approach. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) for dichotomous outcomes. MAIN RESULTS We included two RCTs, with a total of 122 participants. We judged the overall risk of bias as high. We downgraded the evidence due to risk of bias (random sequence generation, allocation concealment, and blinding) and small sample size. The evidence is very uncertain about the effect of probiotics on the occurrence of HAEC (OR 0.58, 95% CI 0.10 to 3.43; I² = 74%; 2 studies, 120 participants; very low-certainty evidence). We found one included study that did not measure serious adverse events and one included study that reported no serious adverse events related to probiotics. Probiotics may result in little to no difference between probiotics and placebo in relation to the severity of children with HAEC at Grade I (OR 0.66, 95% CI 0.14 to 3.16; I² = 25%; 2 studies, 120 participants; low-certainty evidence). The effects of probiotics on the severity of HAEC at Grade II are very uncertain (OR 1.14, 95% CI 0.01 to 136.58; I² = 86%; 2 studies, 120 participants; very low-certainty evidence). Similarly, the evidence suggests that probiotics results in little to no difference in relation to the severity of HAEC at Grade III (OR 0.43, 95% CI 0.05 to 3.45; I² = 0%; 2 studies, 120 participants; low-certainty evidence). No overall mortality or withdrawals due to adverse events were reported. Probiotics may result in little to no difference in the recurrence of episodes of HAEC compared to placebo (OR 0.85, 95% CI 0.24 to 3.00; 1 study, 60 participants; low-certainty evidence). AUTHORS' CONCLUSIONS There is currently not enough evidence to assess the efficacy or safety of probiotics for the prevention of Hirschsprung-associated enterocolitis when compared with placebo. The presence of low- to very-low certainty evidence suggests that further well-designed and sufficiently powered RCTs are needed to clarify the true efficacy of probiotics.

Abstract
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.

Abstract
OBJECTIVES Our institution had modified the Soave pull-through procedure using laparoscopic stepwise gradient muscular cuff cutting (LSGC) for Hirschsprung disease (HSCR). However, we found that a few children still suffered from obstructive symptoms and enterocolitis during the follow-up. Previous studies suggested that these symptoms might be caused by the retained muscular cuff. The purpose of this study was to employ a modified procedure of laparoscopic complete excision of the posterior muscular cuff (LCEPC) for HSCR and compare it with the laparoscopic stepwise gradient cutting muscular cuff (LSGC) procedure. METHODS Our institution records of 83 patients with classic form HSCR who underwent LSGC or LCEPC between August 2014 and July 2018 at the Pediatric Surgery Department of Zunyi Medical University (Zunyi, China) were carefully reviewed (LSGC, n = 52; LCEPC, n = 31). In the present study, we compared the postoperative complications and defecation functions of the two groups. All patients were followed-up (1-5 years, with an average of 2 years). RESULTS There were no differences regarding the operation time and the length of hospitalization between groups, while the anal dissection time in the LCEPC group (22.4 ± 4.8 min) was shorter than that of the LSGC group (45.5 ± 7.5 min) (p < 0.001). The postoperative complication of soiling was significantly increased in six patients (19.4%) in the LCEPC group compared with two patients (3.8%) in the LSGC group (p = 0.021). However, the total incidence of enterocolitis (two patients, 6.5%) was significantly decreased in the LCEPC group compared with the LSGC group (12 patients, 23.1 %) (p = 0.050). For anastomotic stricture, muscular cuff infection, and constipation, there were no significant differences between the two groups. No patients experienced bladder paralysis and incontinence postoperatively in this study. Anorectal manometries presented that the anorectal resting pressure was significantly lower in the LCEPC group (14.8 ± 2.7 mmHg) than the LSGC group (22.0 ± 3.8 mmHg), (p < 0.001). CONCLUSION The laparoscopic complete excision of the posterior muscular cuff method was demonstrated as safe and efficient, with a decrease in the incidence of enterocolitis, although it may increase the number of soiling incidents in the short period post-surgery owing to a dissected partial internal anal sphincter.

Microorganisms 2021; 9:microorganisms9112241. [PMID: 34835367 PMCID: PMC8623574 DOI: 10.3390/microorganisms9112241] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 10/12/2021] [Accepted: 10/21/2021] [Indexed: 01/01/2023] Open
Abstract
Hirschsprung-associated enterocolitis (HAEC) is a common life-threatening complication of Hirschsprung disease (HSCR). It has been proposed that gut microbiota, which have an essential role in gut-homeostasis, are associated with HAEC. Recent studies demonstrated an increase in alpha diversity of fecal microbiota over time in HSCR mice and a decrease in diversity after surgery. In addition, clinical studies have reported a reduction in bacterial richness in HSCR children after surgery. Some studies revealed a difference in microbiota between the proximal ganglionic and distal aganglionic intestine and found a difference in bacterial character between fecal and colonic specimens. HAEC studies found an increase in Proteobacteria, especially Escherichia and Enterobacteriaceae, with a decrease in Firmicutes and Bifidobacterium in HAEC patients. However, the direction of alpha diversity in HAEC patients is still controversial. The self-comparison of microbiota in treatment periods suggested that probiotics might improve gut dysbiosis and decrease the frequency of enterocolitis, but some reported contradictory findings. This review comprehensively summarizes and discusses key findings from animal and clinical data of the distinct microbiome associated with HCSR and the association of gut dysbiosis with the development of HAEC. This information should be useful in the establishment of novel interventions to improve gut dysbiosis and prevent enterocolitis in HSCR patients.

Abstract
PURPOSE OF REVIEW Ideally, after operative intervention, a child born with Hirschsprung disease (HD) should thrive, achieve fecal continence, and avoid recurrent episodes of abdominal distention and enterocolitis. However, a significant number of patients continue to struggle following their pull-through procedure. The purpose of this review is to present an organized and practical approach to the evaluation and management of the symptomatic patient post pull-through operation for HD. RECENT FINDINGS Children diagnosed with HD who are not doing well after their initial operation can be categorized in three distinct groups: (1) those that have fecal incontinence, (2) those with obstructive symptoms, and (3) those with recurrent episodes of enterocolitis. It is important to have a systematic diagnostic approach for these patients based on a comprehensive protocol. All three of these patient groups can be treated with a combination of either medical management, reoperation when a specific anatomic or pathologic etiology is identified, or botulinum toxin for non-relaxing sphincters contributing to the obstructive symptoms or recurrent enterocolitis. For patients not doing well after their initial pull-through, a systematic workup should be employed to determine the etiology. Once identified, a multidisciplinary and organized approach to management of the symptomatic patients can alleviate most post pull-through symptoms.

Abstract
Chronic refractory constipation (CRC) is defined as children who are unable to pass stools in spite of being on maximum laxative therapy and require daily rectal stimulation in the form of enemas or suppositories to pass stools for >3 months. Children are often referred for treatment of refractory constipation that may result from uncontrolled underlying disease or ineffective treatment. Constipated children can be managed by a variety of medical therapeutic options that yield satisfying results in most cases. However, a subset of constipated children fails to benefit from conventional treatments. On treatment failure or on suspicion of organic disease the patient should be referred for further evaluation. Treatment options for treatment-resistant patients are presented. Pharmalogical and non-pharmalogical treatment modalities are reviewed and an algorithm for refractory constipation in children are presented.

Abstract
INTRODUCTION Hirschsprung-associated enterocolitis (HAEC) accounts for substantial morbidity and mortality in patients with Hirschsprung disease (HD). The aim of this study was to identify incidence of pre- and postoperative HAEC in our consecutive cohort and to identify patient and clinical characteristics that are associated with developing postoperative HAEC and HAEC-free interval. MATERIAL AND METHODS A retrospective cohort study was performed with all 146 HD patients treated between 2000 and 2017. Data were retrieved from the medical records. HAEC was defined as presence of clinical signs of bowel inflammation, that required treatment with intravenous antibiotics and admittance to the hospital during at least two days. To identify risk factor for HAEC, patients with and without a history of postoperative HAEC were compared. Kaplan-Meier and Cox-regression were used to assess HAEC free intervals before and after surgery. RESULTS Out of 146 patients, 12 patients had pre-operative HAEC (8%) and 31 patients had postoperative HAEC (21%). Median preoperative HAEC free interval was 112 days (IQR 182 days). Length of hospital stay due to readmissions was longer for patients with a history of postoperative HAEC compared to patients without a history of postoperative HAEC (9.5 vs 16 days, U = 1872.5, p = 0.047). Median postoperative HAEC free interval was 226 days. Of the patients who had postoperative HAEC, 66% had their first episode within the first year after surgery and that the incidence of HAEC declined over follow-up. CONCLUSIONS HAEC incidence was relatively low in our population. No patient or clinical characteristics were associated with the risk of postoperative HAEC.

Abstract
The majority of children who undergo operative management for Hirschsprung disease have favorable results. A subset of patients, however, have long-term dysfunctional stooling, characterized by either frequent soiling or obstructive symptoms. The evaluation and management of a child with poor function after pull-through for Hirschsprung disease should be conducted by an experienced multidisciplinary team. A systematic workup is focused on detecting pathologic and anatomic causes of pull-through dysfunction. This includes an exam under anesthesia, pathologic confirmation including a repeat biopsy, and a contrast enema, with additional studies depending on the suspected etiology. Obstructive symptoms may be due to technique-specific types of mechanical obstruction, histopathologic obstruction, or dysmotility-each of which may benefit from reoperative surgery. The causes of soiling symptoms include loss of the dentate line and damage to the anal sphincter, which generally do not benefit from revision of the pull-through, and pseudo-incontinence, which may reveal underlying obstruction. A thorough understanding of the types of complications associated with various pull-through techniques aids in the evaluation of a child with postoperative dysfunction. Treatment is specifically tailored to the patient, guided by the etiology of the patient's symptoms, with options ranging from bowel management to redo pull-through procedure. This review details the workup and management of patients with complications after pull-through, with a focus on the perioperative management and technical considerations for those who require reoperation.

Abstract
BACKGROUND Patients with Hirschsprung disease may have obstructive symptoms after resection of the aganglionic segment. Botulinum toxin (BT) injections can help improve faecal passage by relaxing the internal anal sphincter. This study assess effect of BT injections and aims to identify factors associated with receiving BT injections and favourable response to the first BT injection. METHODS A retrospective study was performed in a cohort of consecutive patients treated for Hirschsprung disease in our centre between 2003 and 2017. The indication for BT injections was obstructive defecation problems that were non-responsive to high-dose laxatives or rectal irrigation, or an episode of Hirschsprung-associated enterocolitis (HAEC). Effectiveness of BT injections was measured in terms of clinical improvement. Relationships between factors associated with receiving BT injections and with response to the first BT injection were tested with group comparison and logistic regression. RESULTS Forty-one out of 131 patients received BT injections (31%) with a median of two injections (range 1-11). All patients had obstructive defecation problems non-responsive to high-dose laxatives or rectal irrigation, two patient also had an episode of HAEC. Twenty-five out of 41 patients (61%) had clinical improvement after first injection. In 29 of the 41 patients (71%) spontaneous defecation or treatment with laxatives only was achieved. Adverse effects were seen in 12 out of 41 patients (29%) after 14 injections (16%), and consisted of anal pain, temporary loss of stools and dermatitis. Patients who received BT injections more often had long segment disease, more often required laxatives or rectal irrigation and had longer length of hospital stay, both after corrective surgery and in follow-up. None of the tested factors was associated with clinical improvement after first BT injection. CONCLUSION Our findings show that BT injections effectively treat obstructive defecation problems in the majority of patients with Hirschsprung disease with mild adverse effects.

Abstract
INTRODUCTION The current understanding of Hirschsprung-associated enterocolitis (HAEC) is based mainly on single-center, retrospective studies. The aims of this study are to determine risk factors for postoperative HAEC using the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) database. MATERIALS AND METHODS We performed a multicenter, retrospective, case-control study of children with Hirschsprung disease (HD) who had undergone a pull-through procedure and were evaluated at a PCPLC member site between February 2017 and March 2020. The cohort with a history of postoperative HAEC was compared with that without postoperative episodes of HAEC to determine relevant associations with postoperative HAEC. RESULTS One-hundred forty of 299 (46.8%) patients enrolled had a history of postoperative HAEC. Patients with a rectosigmoid transition zone had a lower association with postoperative HAEC as compared with those with a more proximal transition zone (odds ratio [OR]: 0.46, 95% confidence interval [CI]: 0.26, 0.84, p < 0.01). Private insurance was protective against postoperative HAEC on univariate analysis (OR: 0.62, 95% CI: 0.38, 0.99, p = 0.047), but not on multivariate analysis (OR: 0.62, 95% CI: 0.37, 1.04, p = 0.07). Preoperative HAEC was not associated with the development of postoperative HAEC. CONCLUSION Patients with a rectosigmoid transition zone have less postoperative HAEC compared with patients with a more proximal transition zone. Multi-institutional collection of clinical information in patients with HD may allow for the identification of additional risk factors for HAEC and afford the opportunity to improve care.

Abstract
PURPOSE The risk factors for postoperative Hirschsprung-associated enterocolitis (HAEC) are still incompletely understood, especially age at which surgery is performed. Therefore, the aim of this study was to identify the risk factors for the development of postoperative HAEC in children operated during infancy. METHODS Thirty-five children who had undergone radical surgery for Hirschsprung disease (HD) during infancy were included in the study. They were divided into two groups; those who developed postoperative HAEC (HAEC, 14 patients) and those who did not (no HAEC, 21 patients). Their medical records were retrospectively reviewed for clinical details. RESULTS Developing postoperative HAEC was significantly associated with long-segment HD (p = 0.020) and the age at radical surgery (p = 0.0241). No other factors had a significant association with postoperative HAEC. In the patients who developed postoperative HAEC (n = 14), those with Trisomy 21 had significantly longer hospitalizations than those without. Patients with long-segment HD had a higher hospitalization rate than those with short-segment HD. CONCLUSION This study clearly showed that long-segment HD and older age at radical surgery are risk factors for developing postoperative HAEC.

Abstract
INTRODUCTION Patients with Hirschsprung's disease (HSCR) remain at risk of developing Hirschsprung-associated enterocolitis (HAEC) after surgical intervention. As inpatient management remains variable, our institution implemented an algorithm directed at standardizing treatment practices. This study aimed to compare the outcomes of patients pre- and post-algorithm. METHODS A retrospective review of patients admitted for HAEC was performed; January 2017-June 2018 encompassed the pre-implementation period, and October 2018-October 2019 was the post-implementation period. Demographics and outcomes were compared between the two groups. RESULTS Sixty-two episodes of HAEC occurred in 27 patients during the entire study period. Sixteen patients (59%) had more than one episode. The most common levels of the transition zone were the rectosigmoid (50%) and descending colon (27%). Following algorithm implementation, the median length of stay (2 vs. 7 days, p < 0.001), TPN duration (0 vs. 5.5 days, p < 0.001), and days to full enteral diet (6 days vs. 2 days, p < 0.001) decreased significantly. Readmission rates for recurrent enterocolitis were similar pre- and post-algorithm implementation. CONCLUSION The use of a standardized algorithm significantly decreases the length of stay and duration of intravenous antibiotic administration without increasing readmission rates, while still providing appropriate treatment for HAEC. LEVEL OF EVIDENCE III level. TYPE OF STUDY Retrospective comparative study.

Abstract
PURPOSE Awareness of Hirschsprung's-associated enterocolitis (HAEC) among patient's families and medical staff can lead to prompt recognition of symptoms and earlier implementation of management. We designed an HAEC medical alert card to raise awareness of HAEC among medical staff and carers of children with Hirschsprung's disease (HD). Our aim was to investigate parental opinion on the utility of this tool. METHODS All patients diagnosed with HD in two institutions over a period of 14 years received an HAEC alert card and were invited to answer a 1-year follow-up structured questionnaire. RESULTS A total of 123 patients received an HAEC card. The response rate for the follow-up questionnaire was 62% (n = 76). The majority 96% (n = 73) of the responders considered the card useful. A total of 89% (n = 68) of patients or parents stated that they carry the card with them, while 39% (n = 30) of them have used it on 57 occasions. The majority (83%; n = 25) of these declared that, when presented, the card increased awareness among medical staff and on 53% (n = 16) occasions prompted contact with the tertiary centre. CONCLUSION The HAEC medical card was found useful by most parents of HD patients. This tool increased awareness of HAEC and improved communication between peripheral hospitals and tertiary paediatric institutions. Therefore, we feel the HAEC alert card may be used in institutions with high HD addressability.

Abstract
Endorectal pullthrough surgery is integral in the treatment of patients with Hirschsprung disease. Several different surgical procedures exist, which share as common goals to excise the aganglionic segment and upstream transition zone and attach ganglionic bowel just proximal to the anal canal. The operation requires collaboration between surgeon and pathologist to localize ganglionic bowel and prevent retention of transition zone. Intraoperative frozen sections are extremely important, first to establish that ganglion cells are present and subsequently to exclude features of transition zone (partial circumferential aganglionosis, myenteric hypoganglionosis, and submucosal nerve hypertrophy) at the proximal surgical (anastomotic) margin. Postoperative histopathological analysis of resection specimens should be tailored to document distal aganglionosis, document the length of the aganglionic segment and its proximity to the anastomotic margin, and confirm that transition zone has been resected completely. Adherence to the recommendations described in this review will reduce the likelihood of transition zone pullthrough and should decrease the incidence of persistent postoperative obstructive symptoms.

Abstract
BACKGROUND A large proportion of patients with Hirschsprung disease experience persistent obstructive symptoms after corrective surgery. Persistent obstructive symptoms may result in faecal stasis that can develop into Hirschsprung-associated enterocolitis, a potential life-threatening condition. Important treatment to improve faecal passage is internal anal sphincter relaxation using botulinum toxin injections.
AIM To give an overview of all empirical evidence on the effectiveness of botulinum toxin injections in patients with Hirschsprung disease.
METHODS A systematic review and meta-analysis was done by searching PubMed, EMBASE and the Cochrane Library, using entry terms related to: (1) Hirschsprung disease; and (2) Botulinum toxin injections. 14 studies representing 278 patients met eligibility criteria. Data that were extracted were proportion of patients with improvement of obstructive symptoms or less enterocolitis after injection, proportion of patients with adverse effects and data on type botulinum toxin, mean dose, average age at first injection and patients with associated syndromes. Random-effects meta-analysis was used to aggregate effects and random-effects meta-regression was used to test for possible confounding factors.
RESULTS Botulinum toxin injections are effective in treating obstructive symptoms in on average 66% of patients [event rate (ER) = 0.66, P = 0.004, I2 = 49.5, n = 278 patients]. Type of botulinum toxin, average dose, average age at first injections and proportion of patients with associated syndromes were not predictive for this effect. Mean 7 duration of improvement after one botulinum toxin injections was 6.4 mo and patients needed on average 2.6 procedures. There was a significant higher response rate within one month after botulinum toxin injections compared to more than one month after Botulinum toxin injections (ER = 0.79, vs ER = 0.46, Q = 19.37, P < 0.001). Botulinum toxin injections were not effective in treating enterocolitis (ER 0.58, P = 0.65, I2 = 71.0, n = 52 patients). There were adverse effects in on average 17% of patients (ER = 0.17, P < 0.001, I2 = 52.1, n = 187 patients), varying from temporary incontinence to mild anal pain.
CONCLUSION Findings from this systematic review and meta-analysis indicate that botulinum toxin injections are effective in treating obstructive symptoms and that adverse effects were present, but mild and temporary.

Abstract
PURPOSE To define the practice of management for Hirschsprung disease (HD) in Australia and New Zealand. METHODS Online survey of Australian and New Zealand Association of Paediatric Surgeons (ANZAPS) members. RESULTS 56/80 (70%) members from 17 centres responded. DIAGNOSIS 100% perform suction rectal biopsies; 40% perform a contrast enema. HISTOPATHOLOGICAL STAINING H&E (94%), ACHE (70%) and calretinin (75%). SURGERY Primary pull-through (PT) is performed by 88% (100% by < 6/12 months). The Soave-Boley PT is the preferred approach (85%), with laparoscopic assistance (77%) and muscle cuff division (93%). Routine post-operative dilatations are performed by 63% of respondents. If symptoms persist following PT, majority adopt a conservative approach (enemas/laxatives 90%; Botox 74%). If a long-segment is identified at PT, 60% fashion a stoma and delay definitive surgery. If total colonic aganglionosis is identified at PT, 76% fashion a stoma and delay definitive surgery. A dedicated bowel management program is available in 45% of centres with transition to adult services in 29%. CONCLUSIONS A laparoscopic-assisted Soave-Boley PT is the most common technique for recto-sigmoid HD. Differences are noted in both the management of long-segment/total aganglionosis HD and post-operative management/follow-up.
