The Prevalence and Clinical Impact of Transition Zone Anastomosis in Hirschsprung Disease: A Systematic Review and Meta-Analysis. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1475. [PMID: 37761437 PMCID: PMC10528601 DOI: 10.3390/children10091475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 08/18/2023] [Accepted: 08/23/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND Hirschsprung disease (HD) is characterized by absent neuronal innervation of the distal colonic bowel wall and is surgically treated by removing the affected bowel segment via pull-through surgery (PT). Incomplete removal of the affected segment is called transition zone anastomosis (TZA). The current systematic review aims to provide a comprehensive overview of the prevalence and clinical impact of TZA. METHODS Pubmed, Embase, Cinahl, and Web of Sciences were searched (last search: October 2020), and studies describing histopathological examination for TZA in patients with HD were included. Data were synthesized into aggregated Event Rates (ER) of TZA using random-effects meta-analysis. The clinical impact was defined in terms of obstructive defecation problems, enterocolitis, soiling, incontinence, and the need for additional surgical procedures. The quality of studies was assessed using the Newcastle-Ottawa Scale. KEY RESULTS This systematic review included 34 studies, representing 2207 patients. After excluding series composed of only patients undergoing redo PT, the prevalence was 9% (ER = 0.09, 95% CI = 0.05-0.14, p < 0.001, I2 = 86%). TZA occurred more often after operation techniques other than Duhamel (X2 = 19.21, p = <0.001). Patients with TZA often had obstructive defecation problems (62%), enterocolitis (38%), soiling (28%), and fecal incontinence (24%) in follow-up periods ranging from 6 months to 13 years. Patients with TZA more often had persistent obstructive symptoms (X2 = 7.26, p = 0.007). CONCLUSIONS AND INFERENCES TZA is associated with obstructive defecation problems and redo PT and is thus necessary to prevent.

[PMID: 37628417 PMCID: PMC10453740 DOI: 10.3390/children10081418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 08/12/2023] [Accepted: 08/17/2023] [Indexed: 08/27/2023]
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 Intrasphincteric botulinum toxin (Botox) injection for symptomatic postoperative anal achalasia in Hirschsprung's disease (HSCR) has found wide application in the last twenty years. The aim of this study was to describe effectiveness and functional outcome of a series of patients treated over a 10-year period. METHODS All consecutive HSCR patients who received intrasphincteric Botox injections between January 2007 and December 2016 were included. Demographic data and clinical features were collected. A detailed questionnaire focusing on outcome in the medium and long-term was administered to all families. RESULTS In the study period 64 intrasphincteric Botox injections were performed in 31 patients. Completed questionnaires were returned by 27 out of 28 eligible patients (96%) reporting improvement or symptoms resolution in 16 (59%). The highest success rates were experienced by patients younger than 4, with long HSCR forms and with recurrent enterocolitis (75%, 100% and 100% of success rates, respectively). No major complications occurred. Minor complications were described by 7 patients (26%). CONCLUSIONS Intrasphincteric Botox injection proved to be feasible, safe and reasonably effective in children with HSCR and postoperative anal achalasia. Infants and toddlers with long HSCR forms and recurrent bouts of enterocolitis are those who would benefit most from this treatment.

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

Abstract
Hirschsprung-associated enterocolitis (HAEC) was described in 1886 by Harald Hirschsprung and is a potentially deadly complication of Hirschsprung Disease. HAEC is classically characterized by abdominal distension, fever, and diarrhea, although there can be a variety of other associated symptoms, including colicky abdominal pain, lethargy, and the passage of blood-stained stools. HAEC occurs both pre-operatively and post-operatively, is the presenting symptom of HSCR in up to 25% of infants and varies in overall incidence from 20 to 60%. This article reviews our current understanding of HAEC pathogenesis, diagnosis, and treatment with discussion of areas of ongoing research, controversy, and future investigation.

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
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
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.

Intrasphincteric botulinum toxin injections for post-operative obstructive defecation problems in Hirschsprung disease: A retrospective observational study. J Pediatr Surg 2021; 56:1342-1348. [PMID: 33288128 DOI: 10.1016/j.jpedsurg.2020.11.025] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 11/11/2020] [Accepted: 11/21/2020] [Indexed: 01/03/2023]
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.

Impact of Botulinum Toxin on Hirschsprung-Associated Enterocolitis After Primary Pull-Through. J Surg Res 2021; 261:95-104.

Abstract
BACKGROUND Hirschsprung-associated enterocolitis (HAEC) is a serious potential complication after primary pull-through surgery for Hirschsprung's disease (HSCR). Administration of anal botulinum toxin (BT) injection may improve obstructive symptoms at the internal anal sphincter, leading to improved fecal passage. The timing of administration and effects on delay or prevention of HAEC are unknown. We hypothesized that BT administration increased the postoperative time to HAEC and aimed to investigate whether anal BT administration after primary pull-through surgery for HSCR is associated with increased time to inpatient HAEC admission development. METHODS We performed a retrospective cohort study examining children with HSCR at US children's hospitals from 2008 to 2018 using the Pediatric Health Information System database with an associated primary pull-through operation performed before 60 d of age. The intervention assessed was the administration of BT concerning the timing of primary pull-through, and two groups were identified: PRO (received BT at or after primary pull-through, before HAEC) and NOT (never received BT, or received BT after HAEC). The primary outcome was time from pull-through to the first HAEC admission. The Cox proportional hazards model was developed to examine the BT administration effect on the primary outcome after controlling for patient-level covariates. RESULTS We examined a total of 1439 children (67 in the PRO and 1372 in the NOT groups). A total of 308 (21.4%) developed at least one episode of HAEC, including 76 (5.3%) who had two or more episodes. Between 2008 and 2018, the frequency of BT administration has increased from three to 20 hospitals with a frequency of administration between 2.2% and 16.2%. Prophylactic BT (PRO) was not associated with increased time to HAEC event on adjusted analysis. CONCLUSIONS Among children with HSCR undergoing primary pull-through surgery, prophylactic BT administration did not demonstrate increased time to first HAEC event. A better-powered study with prophylactic BT is required to determine the effect on HAEC occurrence and timing. LEVEL OF EVIDENCE Level II (retrospective cohort study).

Abstract
Some patients continue to have obstructive symptoms and/or incontinence after pullthrough surgery for Hirschsprung disease. Incontinence can be due to injury to the anal sphincter and/or dentate line, abnormal colonic motility (nonretentive), or a chronic large stool burden (retentive). A diagnostic algorithm based on clinical and pathological evaluations can be applied to distinguish potential etiologies for obstructive symptoms, which segregate into anatomic (mechanical or histopathological) or physiologic subgroups. Valuable clinical information may be obtained by anorectal examination under anesthesia, radiographic studies, and anorectal or colonic manometry. In addition, histopathological review of a patient's original resection specimen(s) as well as postoperative biopsies of the neorectum usually are an important component of the diagnostic workup. Goals for the surgical pathologist are to exclude incomplete resection of the aganglionic segment or transition zone and to identify other neuromuscular pathology that might explain the patient's dysmotility. Diagnoses established from a combination of clinical and pathological data dramatically alter management strategies. In rare instances, reoperative pullthrough surgery is required, in which case the pathologist must be aware of histopathological features specific to redo pullthrough resection specimens.

Abstract
PURPOSE Patients with Hirschsprung disease (HD) can have persistent obstructive symptoms after resection of the aganglionic segment. If obstructive symptoms are treated inadequately, this may lead to recurrent faecal stasis and impaction, and may result in severe distension of the bowel. A permanently distended bowel which not responds to conservative treatment may be an indication for redo surgery. The aim of this study is to describe our experiences and the short-term results of a novel technique: longitudinal antimesenteric resection with a longitudinal anastomosis. METHODS We reviewed the medical records of our three patients who underwent longitudinal resection of severe distended bowel. This technique aims to improve defecation by improving faecal passage and is characterized by resection of the antimesenteric side of the distended intestinal segment, followed by plication with a longitudinal anastomosis. In this paper, this novel technique is described in detail, as well as short-term outcomes. RESULTS All patients had an uneventful recovery after longitudinal antimesenteric resection. During follow-up, the functional outcomes were excellent, with a large improvement of bowel function. All patients were continent for faeces, and treated with low-dose laxatives or occasional preventive irrigation in one patient. There were no more complaints of persistent constipation or soiling. CONCLUSION Longitudinal resection is a surgical redo-procedure offering large benefits for patients with Hirschsprung disease with distended bowel after primary surgery.

Abstract
Botulinum toxin (Botox) was introduced for the management of internal anal sphincter (IAS) achalasia after a pull-through procedure in Hirschsprung disease (HD). We conducted a prospective evaluation of the efficacy and safety of this Botox treatment.Our study group included 15 patients with HD (median age, 4.8 years; range, 1.7-7.4 years) who experienced persistent constipation after pull-through surgery. Rectal biopsy and colon study were performed before Botox injection to exclude agangliosis. Intersphincteric Botox injections (dose, 4 IU/kg) were performed at 3 sites, (3, 6, and 9 o'clock) under general anesthesia. Measured outcomes of efficacy included anorectal manometry, Wexner constipation score and the quality of life score for defecation, measured at baseline and at 2 weeks and 3 months after injection. The Holschneider incontinence score and an assessment of pain, bleeding, heating sensation, and swelling were also performed at follow-up as outcomes of safety.There was no significant change in measured outcomes with Botox treatment. Botox did decrease the number of patients who experienced abdominal distension at 3 months, compared to 2-weeks, post-injection. No major complications were identified, with only 2 cases of anal bleeding that resolved spontaneously. Local tenderness at the injection site was reported by 4 patients, recovering without treatment.The efficacy of Botox, injected into the IAS, for the treatment of achalasia is questionable on short-term follow-up. Larger studies with a longer follow-up period and the use of repeated injections are required to evaluate the evidence for this treatment.

Abstract
Although most children with Hirschsprung disease ultimately achieve functional and comfortable stooling, some will experience a variety of problems after pull-through surgery. The most common problems include soiling, obstructive symptoms, enterocolitis, and failure to thrive. The purpose of this guideline is to present a rational approach to the management of postoperative soiling in children with Hirschsprung disease. The American Pediatric Surgical Association Hirschsprung Disease Interest Group engaged in a literature review and group discussions. Expert consensus was then used to summarize the current state of knowledge regarding causes, methods of diagnosis, and treatment approaches to children with soiling symptoms following pull-through for Hirschsprung disease. Causes of soiling after pull-through are broadly categorized as abnormalities in sensation, abnormalities in sphincter control, and "pseudo-incontinence." A stepwise algorithm for the diagnosis and management of soiling after a pull-through for Hirschsprung disease is presented; it is our hope that this rational approach will facilitate treatment and optimize outcomes.

Abstract
OBJECTIVES In Hirschsprung disease (HD), despite successful surgical treatment, 50% of children experience long-term functional gastrointestinal problems, particularly chronic functional obstructive symptoms. We report our experience regarding clinical effects of neurostimulation-guided anal intrasphincteric botulinum toxin (BT) injections on postoperative obstructive symptoms attributed to a nonrelaxing anal sphincter complex in HD patients. METHODS In this monocenter cohort study, 15 HD patients with postoperative functional intestinal obstructive symptoms received neurostimulation-guided anal intrasphincteric BT injections. Short-, medium-, and long-term effects were evaluated. The Bristol stool form scale was used to assess stool consistency, and the Jorge-Wexner (JW) score to assess fecal continence. RESULTS The median age at first injection was 4 years. In the short-term, a significant improvement in stool consistency was noted in 12 of 14 patients (P = 0.0001) and JW score decreased for 14 of 15 patients (P = 0.001). In the medium-term, JW score significantly decreased for all patients (P = 0.0001), with an improvement of 50% or more for 10 patients (66.7%). In the long term, 83.3% of patients had normal stool consistency and JW score was <3 for all. Recurrent enterocolitis decreased from 86.7% to 8.3%. A complete resolution of all symptoms without further medication was observed in 66.7% of patients in the long term. CONCLUSIONS Intrasphincteric BT injection was a safe, effective, and durable option for the management of postoperative functional intestinal obstructive symptoms in HD. The use of neurostimulator guidance for specific delivery of BT to muscular fibers of nonrelaxing anal sphincter complex takes into consideration the variability of patient's anatomy secondary to curative surgery.

Abstract
AIM OF THE STUDY The objective of this study is to identify risk factors associated with the development of post-operative enterocolitis (HAEC), in short segment Hirschsprung's disease (HSCR-S). METHODS A retrospective study was carried out for post-operative patients with HSCR-S from 1997 to 2017. HSCR-S was defined as the most proximal extension of aganglionosis limited to the sigmoid colon. An episode of HAEC was defined as the presence of (1) vomiting or explosive diarrhea; (2) abdominal distension; (3) fever and (4) leukocytosis. Risk factors for the development of HACE were determined using multivariate logistic regression. MAIN RESULTS The medical records of 96 patients were reviewed. The overall incidence of HAEC was 20.8% (n = 20) and 65.0% (n = 13) of HAEC occurred within the first year of operation. After a univariate logistic regression analysis, three risk factors for HAEC were identified: (1) presence of other major anomalies [OR: 1.43 (1.12-2.32), p = 0.041]; (2) creation of pre-operative defunctioning stoma [OR: 2.28 (1.47-3.23), p = 0.035]; (3) extension of aganglionosis to the sigmoid colon [OR: 1.89 (1.05-3.19), p = 0.049]. After multivariate logistic regression analysis, a significant association was demonstrated for creation of pre-operative defunctioning stoma [OR: 1.81 (1.08-3.22), p = 0.045] and extension of aganglionosis to the sigmoid colon [OR: 1.91 (1.37-2.98), p = 0.038]. CONCLUSIONS The requirement of pre-operative defunctioning stoma and a more proximal extension of aganglionosis are risk factors for the development of post-operative HAEC in HSCR-S. Patients with these risk factors should be closely followed up especially during the first year after the operation.

Abstract
BACKGROUND/PURPOSE The purpose of this study was to review the management of obstructive symptoms and enterocolitis (HAEC) following pull-through for Hirschsprung's disease. METHODS A systematic review and meta-analysis (1992-2017) was performed. Included studies were: randomized controlled trials (RCT), retrospective/prospective case-control (C-C), case-series (C-S). Random-effect model was used to produce risk ratio (RR) [95% CI]. P < 0.05 was considered significant. RESULTS Twenty-nine studies were identified. Routine postoperative dilatations (5 C-S, 2 C-C; 405 patients): no effect on stricture incidence (RR 0.3 [0.02-5.7]; p = 0.4). Routine postoperative rectal irrigations (2 C-C; 172 patients): reduced HAEC incidence (RR 0.2 [0.1-0.5]; p = 0.001). Posterior myotomy/myectomy (4 C-S; 53 patients): resolved obstructive symptoms in 79% [60.6-93.5] and HAEC in 80% [64.1-92.1]. Botulinum toxin injection (9 C-S; 166 patients): short-term response in 77.3% [68.2-85.2], long-term response in 43.0% [26.9-59.9]. Topical nitric oxide (3 C-S; 13 patients): improvement in 100% of patients. Probiotic prophylaxis (3 RCT; 160 patients): no reduction in HAEC (RR 0.6 [0.2-1.7]; p = 0.3). Anti-inflammatory drugs (1 C-S, sodium cromoglycate; 8 patients): improvement of HAEC in 75% of patients. CONCLUSIONS Several strategies with variable results are available in patients with obstructive symptoms and HAEC. Routine postoperative dilatations and prophylactic probiotics have no role in reducing the incidence of postoperative obstructive symptoms and HAEC. TYPE OF STUDY Systematic review and meta-analysis.

Abstract
Pullthrough procedures for Hirschsprung diseases typically have favorable results. However, some children experience long-term postoperative complications comprising stooling disorders, such as intermittent enterocolitis, severe stool retention, intestinal obstruction, as well as incontinence. Reoperative Hirschsprung Disease surgery is complex. This begins with the workup after the initial presentation following primary pullthrough, continues with the definitive surgical correction with redo pullthrough, and ends with long-term follow-up of individuals. The decision tree can be varied with each patient. The operating pediatric surgeon must be able to utilize different operations and treatment options available. While lesser procedures may provide relief in a select population, those with residual aganglionosis or transition zone pathology or mechanical problems will likely require a redo pullthrough. Thus, the diagnostic workup, treatment plan, and definitive surgical care should be coordinated, and executed by an experienced, specialized team at a pediatric referral center.

Abstract
PURPOSE Chronic obstructive defecation can occur in patients with Hirschsprung Disease (HD) and internal anal sphincter (IAS) achalasia. Injection of Botulinum Toxin (BoTox) into the IAS can temporarily relieve obstructive defecation, but can be challenging when performed by tactile sense alone. We compared results of BoTox injections with and without ultrasound (US) guidance. METHODS We retrospectively reviewed BoTox injections into the IAS for obstructive defecation over 5years. Analyzed outcomes included short-term improvement, defined as resolution of enterocolitis, new ability to spontaneously defecate, and/or normalization of bowel movement frequency 2weeks post-operatively, as well as requirement of more definitive surgical therapy (myotomy/myomectomy, colectomy, colostomy, cecostomy/appendicostomy, and/or sacral nerve stimulator implantation). Outcomes were compared using t-test and Fisher's Exact test, with significance defined as p<0.05. RESULTS Twelve patients who underwent BoTox injection were included, including 5 patients who underwent injections both with and without ultrasound. Ten underwent an ultrasound-guided injection (13 injection procedures), 5 of whom had HD. Seven underwent an injection without ultrasound guidance (17 injection procedures), 5 of whom had HD. Procedures performed with US resulted in greater short-term improvement (76% versus 65% without ultrasound) and less requirement of a definitive procedure for obstructive defecation (p<0.05). CONCLUSIONS US-guided BoTox injection is safe and effective for obstructive defecation, and may decrease the need for a definitive operation. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to evaluate the result of posterior myectomy in children with chronic constipation who underwent to this surgery. METHODS Forty eight children with chronic constipation who did not respond to diet, laxative, or enema were included. Children with abnormal barium enema showing transitional zone were excluded. Children with documented metabolic disease diabetes, and hypothyroidism were also excluded. All patients underwent posterior myectomy. Children were followed during 1 year after surgery regarding frequency of fecal evacuation, fecal consistency, straining during defecation, and diameter of feces. Data was analyzed using SPSS version 13.0 (Chicago, IL, USA). RESULTS Of 48 cases that underwent surgery, 21 were male and 27 were female. Age range was 1.5 to 11 years old. Mean duration of constipation before surgery was 22.79±17.08 (range 6-48 months). Mean duration of medical treatment was 14.90±10.31 (range= 6-48 months). Fecal consistency, feces diameter, number of bowel movements and straining during defecation were compared before and after surgery. The results were statistically significant ( P <0.001). Of all cases, 52% continued treatment of constipation after surgery for 1 year. Ganglion cells were absent in 32 cases. Ganglion cells were present in seven children. Proximal ganglion cell was found in nine cases Treatment response was not different between cases according to status of ganglion cell in biopsy. CONCLUSION Fecal consistency, feces diameter, number of bowel movements, and straining for defecation were improved after posterior myectomy. Another study with more sample is required for better evaluation of treatment.

Abstract
More than a century has elapsed since the identification of Clostridia neurotoxins as the cause of paralytic diseases. Clostridium botulinum is a heterogeneous group of Gram-positive, rod-shaped, spore-forming, obligate anaerobic bacteria that produce a potent neurotoxin. Eight different Clostridium botulinum neurotoxins have been described (A-H) and 5 of those cause disease in humans. These toxins cause paralysis by blocking the presynaptic release of acetylcholine at the neuromuscular junction. Advantage can be taken of this blockade to alleviate muscle spams due to excessive neural activity of central origin or to weaken a muscle for treatment purposes. In therapeutic applications, minute quantities of botulinum neurotoxin type A are injected directly into selected muscles. The Food and Drug Administration first approved botulinum toxin (BT) type A in 1989 for the treatment of strabismus and blepharospasm associated with dystonia in patients 12 years of age or older. Ever since, therapeutic applications of BT have expanded to other systems, including the gastrointestinal tract. Although only a single fatality has been reported to our knowledge with use of BT for gastroenterological conditions, there are significant complications ranging from minor pain, rash and allergic reactions to pneumothorax, bowel perforation and significant paralysis of tissues surrounding the injection (including vocal cord paralysis and dysphagia). This editorial describes the clinical experience and evidence for the use BT in gastrointestinal motility disorders in children.

Abstract
BACKGROUND Obstructive symptoms are common after pull-through for Hirschsprung disease. Botulinum toxin injection treatment may improve the bowel function if internal sphincter achalasia is the cause of obstructive symptoms. The aim of this study was to review the outcome in patients treated with intrasphincteric botulinum toxin injections after pull-through for Hirschsprung disease. METHODS The operative records were used to identify children with Hirschsprung disease who were treated with botulinum toxin injections at Karolinska University Hospital, Stockholm, Sweden, from September 2007 to November 2014. Data on age, sex, associated syndromes, length of aganglionic segment, age at pull-through, type of pull-through, age at first botulinum toxin injection, indication for botulinum toxin injection, and effect of first botulinum toxin injection were retrieved from the case records. Bowel function at last follow-up visit or telephone contact was recorded. RESULTS Nineteen patients were identified. All had biopsy-verified Hirschsprung disease. Eighteen (15 males and 3 females) children had undergone intrasphincteric botulinum toxin injection treatment for obstructive symptoms after pull-through, which was done at 127 (18-538) days of age. Four children had total colonic aganglionosis. The first botulinum toxin injection was given at 2.4 (0.53-6.9) years of age. Thirteen children (72 %) had a good response to the first injection treatment. The children underwent 3 (1-13) injection treatments. At follow-up four patients had improved and did not need treatment for obstruction, four were scheduled for further botulinum toxin injections, eight had persistent obstructive symptoms treated with laxatives or enemas, and two children had an ileostomy. CONCLUSION Botulinum toxin injection treatment improves the obstructive symptoms in children after pull-through for Hirschsprung disease. The effect is reversible and a majority of patients need repeat injections. When injection treatment is not repeated, a large proportion of children need laxatives or enemas due to recurrent symptoms.

Abstract
OBJECTIVES A nonrelaxing internal anal sphincter is present in a relatively large proportion of children with surgically treated Hirschsprung disease (HD) and can cause obstructive gastrointestinal symptoms. The short- and long-term outcome and adverse effects of intrasphincteric botulinum toxin (Botox) injections in children with obstruction after surgically treated HD are evaluated. METHODS The outcome of children with surgically treated HD treated with intrasphincteric Botox injections for obstructive symptoms was analyzed with a retrospective chart review between 2002 and 2013 in the University Medical Centers of Maastricht and Nijmegen. RESULTS A total of 33 patients were included. The median time of follow-up was 7.3 years (range 1-24). A median of 2 (range 1-5) injections were given. Initial improvement was achieved in 76%, with a median duration of 4.1 months (range 1.7-58.8). Proportion of children hospitalized for enterocolitis decreased after treatment from 19 to 7. A good long-term response was found in 49%. Two children experienced complications: transient pelvic muscle paresis with impairment of walking. In both children symptoms resolved within 4 months without treatment. CONCLUSIONS Intrasphincteric Botox injections in surgically treated HD are an effective long-term therapy in approximately half of our patients with obstructive symptoms. The possibility of adverse effects should be noticed.

Abstract
INTRODUCTION This study presents our surgical experience for redo-pullthrough (RedoPT) for Hirschsprung disease (HD). It reviews the patient's clinical outcomes and assesses stooling patterns after RedoPT. METHODS A retrospective review of our institution's RedoPTs as well as one author's overseas cases was performed. Stooling scores were tabulated using an established survey tool and compared to primary PT matched patients. RESULTS Between 1974 and 2012, 46 individuals (52% males) underwent RedoPT, representing 3 percent of all HD pullthroughs. Median age at primary PT and RedoPT was 1year (range 1week-18years) and 3.5years (range 8weeks-41years), respectively. Indications for RedoPT were predominately for aganglionosis/transition zone pathology (71%); followed by stricture or an obstructing Duhamel pouch (19%), tight cuff (8%) and a twisted PT (4%). None were performed for an isolated clinical diagnosis of repeated bouts of enterocolitis. RedoPT surgical approach depended upon the initial pullthrough technique and any previous complications. Stooling scores were significantly (P<0.05) worse in the RedoPT patients compared to the historically-matched group of children undergoing a primary PT for HD (5.5±1.2 vs. 12.2±1.4, primary PT versus RedoPT, respectively). When breaking down this total score into individual parameters, stooling pattern scores (1.0±0.2 vs. 4.1±0.4, P=0.001) and enterocolitis scores (2.0±0.4 vs. 4.2±0.4, P=0.001) were statistically worse in the RedoPT group. Patients in both groups had similar overall continence rates. CONCLUSION Appropriately selected children undergoing a RedoPT can achieve good results, with comparable continence rates to those undergoing a primary PT.

Abstract
PURPOSE Following a Soave pull-through for Hirschsprung disease (HD), some children struggle with obstructive symptoms. We hypothesized that these symptoms could result from a functional obstruction of the pull through caused by the Soave cuff, and that cuff resection might improve bowel emptying. METHODS We reviewed patients referred to our center from 2008 to 2012 with obstructive problems following a Soave pull-through for HD (CCHMC IRB # 2011-2019). Only patients with an obstructing Soave cuff were analyzed. Patients with other reasons for obstruction (anastomotic stricture, transition zone, aganglionic segment) were excluded. RESULTS Thirty-six patients underwent reoperation at our center for obstructive symptoms after an initial Soave pull-through. Seventeen of these patients had a Soave cuff only as the potential source of obstruction. Pre-operative symptoms included enterocolitis (10), constipation (6), and failure to thrive (1). Nine patients (53%) required irrigations to manage distension or enterocolitis pre-operatively. 14/17 patients (82%) had a palpable cuff on rectal exam. Eight patients (47%) had radiographic evidence of a cuff demonstrated by distal narrowing (4) or a prominent presacral space (4). Four children (23%) underwent excision of the cuff only. Thirteen (76%) had removal of the cuff and proximally dilated colon [(average length 7.2cm) (12 performed transanally, and five needed laparotomy as well.)] Post-operatively, episodes of enterocolitis were reduced to zero, and need for irrigation to treat distension was reduced by 50%. Nine patients have voluntary bowel movements, and five are clean on enemas. 3/6 patients with pre-operative constipation or impaction now empty without enemas. (Follow up 1-17months, mean 7months.) CONCLUSIONS Recurrent enterocolitis, constipation, or failure to thrive can indicate a functional obstruction due to a Soave cuff when no other pathologic cause exists. Physical exam or contrast enema can identify a problematic cuff. Reoperation with cuff resection can dramatically improve bowel emptying.

Abstract
Hirschsprung-associated enterocolitis (HAEC) is a common and sometimes life-threatening complication of Hirschsprung disease (HD). Presenting either before or after definitive surgery for HD, HAEC may manifest clinically as abdominal distension and explosive diarrhea, along with emesis, fever, lethargy, and even shock. The pathogenesis of HAEC, the subject of ongoing research, likely involves a complex interplay between a dysfunctional enteric nervous system, abnormal mucin production, insufficient immunoglobulin secretion, and unbalanced intestinal microflora. Early recognition of HAEC and preventative practices, such as rectal washouts following a pull-through, can lead to improved outcomes. Treatment strategies for acute HAEC include timely resuscitation, colonic decompression, and antibiotics. Recurrent or persistent HAEC requires evaluation for mechanical obstruction or residual aganglionosis, and may require surgical treatment with posterior myotomy/myectomy or redo pull-through. This chapter describes the incidence, pathogenesis, treatment, and preventative strategies in management of HAEC.

Abstract
The enteric nervous system is the part of the autonomic nervous system that directly controls the gastrointestinal tract. Derived from a multipotent, migratory cell population called the neural crest, a complete enteric nervous system is necessary for proper gut function. Disorders that arise as a consequence of defective neural crest cell development are termed neurocristopathies. One such disorder is Hirschsprung disease (HSCR), also known as congenital megacolon or intestinal aganglionosis. HSCR occurs in 1/5000 live births and typically presents with the inability to pass meconium, along with abdominal distension and discomfort that usually requires surgical resection of the aganglionic bowel. This disorder is characterized by a congenital absence of neurons in a portion of the intestinal tract, usually the distal colon, because of a disruption of normal neural crest cell migration, proliferation, differentiation, survival, and/or apoptosis. The inheritance of HSCR disease is complex, often non-Mendelian, and characterized by variable penetrance. Extensive research has identified a number of key genes that regulate neural crest cell development in the pathogenesis of HSCR including RET, GDNF, GFRα1, NRTN, EDNRB, ET3, ZFHX1B, PHOX2b, SOX10, and SHH. However, mutations in these genes account for only ∼50% of the known cases of HSCR. Thus, other genetic mutations and combinations of genetic mutations and modifiers likely contribute to the etiology and pathogenesis of HSCR. The aims of this review are to summarize the HSCR phenotype, diagnosis, and treatment options; to discuss the major genetic causes and the mechanisms by which they disrupt normal enteric neural crest cell development; and to explore new pathways that may contribute to HSCR pathogenesis.

Abstract
After surgery for Hirschsprungs disease, most children thrive, have few if any episodes of abdominal distention and enterocolitis, and are fecally continent. However, there exists a small group of patients who do not do well. Either they suffer from persistent distension and enterocolitis or they experience soiling after their pull-through procedure. These patients can be systematically evaluated and successfully treated with a combination of bowel management, dietary changes, and laxatives, and, in certain circumstances, a reoperation.

Abstract
Despite most children undergoing a successful pull through for Hirschsprung disease, a small portion of children are left with persistent stooling issues. Most of these stooling issues can be addressed by nonoperative approaches. However, in a small group of remaining children, a reoperation may be necessary. Most children who may need a redo pull-through procedure may have a persistent area of aganglionosis, unremitting enterocolitis, or a torsion or stricture of the pull-through segment. Each of these influences the approach the surgeon must take to correct the presenting problem. The chapter details the diagnostic approach as well as the operative techniques, which best deal with each of these complications.

Abstract
PURPOSE Most patients with Hirschsprung's disease (HD) have a satisfactory outcome after pull-through (PT) operation. However, some children continue to have persistent bowel symptoms after the initial operation and may require redo PT. Redo PT operation in HD is usually indicated for anastomotic strictures or residual aganglionosis (RA). We designed this meta-analysis to determine the incidence and outcome of RA among patients with HD following PT operation. METHODS A meta-analysis of redo PT operations for HD reported in the literature between 1985 and 2011 was performed. Detailed information was recorded in patients with RA and transition-zone bowel (TZB), including recurrent bowel problems, histological findings on repeat rectal biopsy, type of redo PT operation and outcome. RESULTS Twenty-nine articles reported 555 patients with redo PT operations. 193 (34.8%) patients demonstrated abnormal histological findings on rectal biopsy with 144 patients showing RA and 49 patients showing TZB. These 193 patients presented with persistent constipation (n = 135), recurrent enterocolitis (n = 45) and abnormal histology of the pulled-through bowel (n = 13). Mean age at redo PT was 4.4 years (range 4 months-17 years). Redo procedures were Duhamel (n = 57), transanal endorectal PT (n = 40), Soave (n = 35), Swenson (n = 10), posterior sagittal approach (n = 1) and not reported (n = 50). Follow-up information after redo PT was available in 134 (69.4%) patients and not available in 59 patients. Of the 134 patients, 99 (73.9%) patients had normal bowel habits, 19 patients had persistent constipation/soiling and 16 patients had recurrent enterocolitis. CONCLUSION This meta-analysis reveals that RA and TZB are the underlying causes of persistent bowel symptoms in one-third of all patients with HD requiring redo PT operation. Most patients have a satisfactory outcome after redo operation. Rectal biopsy should be performed in all patients with recurrent bowel problems after PT operation.

Abstract
BACKGROUND Reoperations in Hirschsprung disease may be required for residual aganglionosis or transition-zone bowel found at the distal pull-through. We aimed to review the management of patients who had this complication and offer suggestions on how to avoid it. METHODS Ninety-three patients with Hirschsprung disease were referred to our institution with recurrent problems after a pull-through done elsewhere. All required reoperations with a variety of indications, and of these, 25 had residual aganglionosis/transition-zone histology. This was the only indication for redo in 16 children. RESULTS Children (range, 2-17 years) presented 6 to 66 months after the initial pull-through. The predominant symptoms were enterocolitis (n = 9 [56%]), constipation (n = 7 [44%]), failure to thrive (n = 5 [31%]), and impaction (n = 4 [25%]). The rectal biopsy performed as part of their post pull-through work up showed hypertrophic nerves (n = 16), absent ganglion cells (n = 6), and normal ganglion cells (n = 10). The original frozen-section biopsy, determining the level of the pull-through, only sampled the seromuscular layer in 3 children, leading to misdiagnosis. Reoperations involved a transanal resection (n = 15) and a posterior sagittal approach (n = 1). In all cases, obstructive symptoms were resolved, and no patient has had recurrent enterocolitis. CONCLUSION Patients' post pull-through with recurrent obstructive symptoms may have residual aganglionosis or transition-zone bowel. Reoperation can result in the resolution of these symptoms. A full-thickness biopsy at the time of the initial pull-through to include the mucosa and submucosa may increase the possibility of identifying hypertrophic nerves.

Abstract
PURPOSE The transanal one-stage pull-through procedure (TERPT) has gained worldwide popularity over open and laparoscopic-assisted one-stage techniques in children with Hirschsprung's disease (HD). It offers the advantages of avoiding laparotomy, laparoscopy, scars, abdominal contamination, and adhesions. However, enterocolitis associated with Hirschsprung's disease (HAEC) still remains to be a potentially life-threatening complication after pull-through operation. The reported incidence of HAEC ranges from 4.6 to 54%. This meta-analysis was designed to evaluate postoperative incidence of HAEC following TERPT procedure. METHODS A meta-analysis of cases of TERPT reported between 1998 and 2009 was performed. Detailed information was recorded regarding intraoperative details and postoperative complications with particular emphasis on incidence of HAEC. Diagnosis of HAEC in a HD patient was based on the clinical presentation of diarrhoea, abdominal distension, and fever. RESULTS Of the 54 published articles worldwide, 27 articles, including 899 patients were identified as reporting entirely TERPT procedure. Postoperative HAEC occurred in 92 patients (10.2%). Recurrent episodes of HAEC were reported in 18 patients (2%). Conservative treatment of HAEC was successful in 75 patients (81.5%), whereas in 17 patients (18.5%) surgical treatment was needed. CONCLUSIONS This systematic review reveals that TERPT is a safe and less-invasive procedure with a low incidence of postoperative HAEC.

Abstract
BACKGROUND AND AIM Botox injection treatment (BIT) is a potentially effective but yet unproven treatment of functional anal outlet obstruction that is caused by non-relaxing internal anal sphincter. We present a single institution experience of BIT from 2005 to 2008. PATIENTS AND METHODS Sixteen patients (11 males), eight with Hirschsprung's disease (HD) (one with total colon aganglionosis, TCA) and eight with internal sphincter achalasia (ISA) were included. Median ages were 3.8 years (0.4-9.3) for HD and 8.1 years (range 1.5-11.4) for ISA. ISA was defined as the absence of rectoanal inhibitory reflex with normal rectal biopsies. Seven HD patients had previous coloanal pull-through (CAPT), and one (TCA) colectomy and ileoanal J-Pouch anastomosis. Two of the ISA patients had undergone internal sphincter myectomy and two had Malone procedure [antegrade colonic enema (ACE)]. Indication for BIT in 16 patients was anal outlet obstruction (n = 11) with soiling and recurring HD-associated enterocolitis (n = 5) and in one patient (HD, TCA) soiling with enterocolitis (n = 1). Before BIT, all patients underwent anorectal manometry, rectal biopsies and barium enema. The effect of BIT was evaluated after 2 months and BIT was repeated if necessary. Effect of BIT was scored as follows: 0 no, 1 little, 2 significant effect and 3 symptoms disappeared. RESULTS Median follow-up was 19 months (range 3-43). The median number of injections was two per patient (range 1-4) and the median Botox dose was 80 U (range 40-100). Scores of BIT effect were 3 or 2 in five (31%) and 0 or 1 in 11 (69%). After adjunctive treatment modalities (myectomy n = 1, CAPT n = 1, adjusted ACE/laxative treatment), the end result was good or satisfactory in 11 (69%) but remained poor in 5 (31%) patients. Patient age, diagnosis, anorectal resting pressure or findings in barium enema were not correlated with BIT efficiency score (R range -0.06 to 0.39, P = 0.12-0.91). CONCLUSION Although successful in some patients, the role of BIT remains undetermined. It is difficult to predict which patients will profit from BIT. Continuing other treatment modalities after BIT may improve the results.

[PMID: 19361637 PMCID: PMC4372194 DOI: 10.1016/j.jpedsurg.2008.06.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2008] [Revised: 06/10/2008] [Accepted: 06/11/2008] [Indexed: 01/21/2023]
Abstract
BACKGROUND/PURPOSE The study aimed to develop a mouse model of post-pullthrough Hirschsprung's disease that will allow investigation of mechanisms that cause postoperative complications. METHODS We developed a novel microsurgical pullthrough operation on Balb/C mice and evaluated its effect on growth rate and stooling pattern. Histologic assessment of the pullthrough colon was performed. The pullthrough operation was then performed on Ednrb-/- mice that have aganglionic megacolon and Ednrb+/+ littermate controls, and the outcomes compared. RESULTS The Balb/C pullthrough group had 97% survival at 1 week and 70% survival at 2 weeks. Body weight of the pullthrough animals declined 15% in the first week after surgery and subsequently normalized. The stooling pattern showed consistently softer stools in the pullthrough group, but no difference in frequency compared to controls. Histopathologic analyses 4 weeks postoperatively showed well-healed coloanal anastomoses. Two-week survival after pullthrough surgery in Ednrb-/- and Ednrb+/+ mice was 50.0%, and 69.2%, respectively (P = NS). Increased mortality in the Ednrb-/- mice was related to the technical challenge of performing microsurgery on smaller-sized mice with poor baseline health status. CONCLUSIONS Our microsurgical pullthrough operation in mice is feasible and allows systematic investigations into potential mechanisms mediating post-pullthrough complications and poor long-term results in mouse models of Hirschsprung's disease.

Abstract
OBJECTIVES Children with surgically repaired Hirschsprung's disease (HD) and those with internal anal sphincter (IAS) achalasia may develop obstructive gastrointestinal symptoms and/or enterocolitis due to a functional obstruction caused by an inability of the IAS to relax. Anal sphincter Clostridium botulinum toxin (BoTox) injections may provide a reversible therapy. However, there is limited information regarding the long-term outcomes of children receiving this therapy. The primary aim of this study was to determine the long-term clinical outcomes of BoTox therapy in children with a nonrelaxing IAS. The secondary aim of this study was to determine prognostic factors predicting a favorable outcome following BoTox IAS injection. METHODS We conducted a retrospective review of children with nonrelaxing IAS who received anal sphincter BoTox at a tertiary medical center. Children were classified into one of four long-term clinical outcome groups (excellent, good, fair, poor). RESULTS A total of 73 children (30 HD, 43 IAS achalasia) received anal sphincter BoTox injections and had a mean follow-up of 32.1+/-2.9 (s.e.) months. A mean of 2.7+/-0.2 injections were given to each child, with 56 (76.7%) children receiving multiple injections. An initial clinical improvement was seen in 65 of 73 (89%) children after the first injection. A total of 39 (53.4%) children had an excellent or good long-term outcome that was maintained for a mean of 17.1+/-3.1 months from the time of the last BoTox injection. Hospitalization rates significantly decreased in those previously hospitalized before initial BoTox injection. Seven (9.5%) patients developed transient fecal incontinence, and one (1.3%) developed significant pain after an injection. Factors predicting a favorable long-term clinical outcome were initial short-term improvement after the first BoTox injection and having IAS achalasia rather than HD. CONCLUSIONS Anal sphincter BoTox may be an effective and safe long-term therapy for children with nonrelaxing IAS.

Colonic dysmotility in postsurgical patients with Hirschsprung's disease. Potential significance of abnormalities in the interstitial cells of Cajal and the enteric nervous system. J Pediatr Surg 2008; 43:1433-8. [PMID: 18675631 DOI: 10.1016/j.jpedsurg.2007.10.067] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2007] [Accepted: 10/30/2007] [Indexed: 02/06/2023]
Abstract
PURPOSE Normal gut muscular function depends on the coordinated activity of both the enteric nervous system (ENS) and the interstitial cells of Cajal (ICC). Hirschsprung's disease (HD) has long been considered a purely neuronal deficit but recent data point to abnormalities in ICC in the proximal ganglionated HD colon. We examined the labeling of ICC and neuronal cells in the proximal ganglionated colon in patients with HD to determine whether abnormalities of ICC and ENS might be associated with a poor clinical outcome. METHODS Tissue from 11 patients with HD was studied using immunohistochemistry for ICC and neuronal identification in comparison to control tissue from patients without HD. Image data were evaluated quantitatively and interpreted relative to clinical outcome. RESULTS Interstitial cells of Cajal in the ganglionated colon of the HD group did not differ from the control group, but nerve cells/fibers were decreased 40%. Paired decreases in both nerve fibers and ICC in individual patients were associated with normal bowel function. Poor postoperative outcome was observed in a patient with normal innervation but with a profound decrease in ICC in the ganglionated colon. CONCLUSIONS Nerve fibers are decreased in the proximal ganglionated colon in patients with HD without associated gut dysmotility. Poor clinical outcome was noted only in a patient with normal innervation and markedly decreased ICC. Collection of data from a much larger number of patients with poor clinical outcome will be necessary to determine the significance of this imbalance of ICC and innervation.

Abstract
BACKGROUND/PURPOSE In Hirschsprung's disease (HD) redo pull-through (PT) is indicated for anastomotic complications and for persistent aganglionosis after previous definitive surgery. This study was undertaken to evaluate the role of transanal approach to redo PT procedure in the management of complicated cases of HD over the last 7 years. PATIENTS AND METHODS Between November 1998 and September 2005, 225 patients with HD were operated using the transanal endorectal PT (TEPT) approach. Eighteen patients had a redo PT owing to persistent aganglionosis. The present study evaluates the role of TEPT approach in patients with persistent aganglionosis (n = 18). Three patients needed a colostomy (n = 2) or ileostomy (n = 1) before the final operation. All the 18 patients underwent transanal mobilization (TEPT) of the colon. Six patients required additional mobilization of the proximal colon (n = 4) and the ileum (n = 2) during the redo PT operation. RESULTS Median follow-up was 43 months (range, 3-72 months). Sixteen patients have had a good outcome with stool pattern 1 to 4 times daily. One patient had obstructive symptoms for 4 months postoperatively but then settled. One patient has occasional soiling. CONCLUSIONS In this series, TEPT and posterior midline split of the muscle cuff were used with good results. This has the advantage of avoiding injury to the pelvic muscles and nerves. The TEPT approach is combined with transabdominal mobilization of the intestine depending on the length of the aganglionic segment. The outcome has been favorable, but long-term follow-up is necessary for full assessment of those patients.

Abstract
Although various surgical procedures have been described to treat Hirschsprung's disease (HD), few studies have evaluated the long-term results of these children. The purpose of this study was to assess the long-term clinical outcome and bowel function of patients with HD. The hospital records of 259 consecutive patients with a confirmed histological diagnosis of HD during 1975-2003 were examined. Data was assessed for age at presentation, sex, clinical presentation, associated anomalies, level of aganglionosis, surgical procedures, complications and bowel function. Follow up was carried out by personal/telephone interviews with patients or their parents. Of the 259 patients with HD, 200 were males (77.2%) and 59 females (22.8%). Intestinal obstruction was the presenting feature in 147 patients (56.8%), intestinal perforation in 5 (1.9%), enterocolitis in 30 (11.6%) and constipation in 77 (29.7%). Thirty-nine patients (15.1%) had associated Down's syndrome. Two hundred and nine patients (80.7%) had rectosigmoid disease, 31 (12%) had long segment disease and 19 (7.3%) had total colonic aganglionosis. Forty-three patients (16.6%) had preoperative enterocolitis. Primary colostomy was performed in 160 patients and a primary pull through in 90. Seven patients had a sphincteromyectomy for ultrashort HD. Two patients died prior to treatment. Various pull through procedures were performed in these patients. Postoperative complications included: pelvic abcess in 2, rectal stricture in 10, perianal excoriation in 7, anastomotic leak in 8, intestinal obstruction in 3, wound dehiscence in 1, stomal prolapse/stenosis in 5, rectovesical fistula in 2 and enterocolitis in 56. Five patients underwent a redo pull through and 46 required a post pull through sphincterectomy. At the time of follow-up, 27 were lost to follow-up, 9 died, 18 had permanent stomas and 4 were too young to assess bowel function. Of the remaining 194 patients, bowel function was normal in 132 (68%). Twenty patients (10.3%) had soiling and 42 (21.7%) had constipation requiring laxatives or enemas. There was no difference in bowel function in relation to type of pull through operation. Only 34% of patients with Down's syndrome had normal continence. The majority of patients with HD continue to have disturbances of bowel function for many years before attaining normal continence.

Abstract
The management of Hirschsprung's disease (HD) has made dramatic strides over the last 20 years. Research into the embryological development and migration of ganglion cell has enabled a greater understanding of the pathogenesis of the disease. Coupled with new techniques in surgery, such as laparoscopy-assisted pull-through and the transanal pull-through, this knowledge has led to improved outcomes for children with HD. However, although our appreciation of Hirschsprung's associated enterocolitis and its aetiology has increased, there are continued references in the literature to a multitude of theories of pathogenesis. The purpose of this review is to delineate the theories and demonstrate the evidence supporting or otherwise contradicting each other.
