Reoperative Anorectal Procedures in Patients with Anorectal Malformations - Is Bladder Function Affected? J Pediatr Surg 2023; 58:1910-1915. [PMID: 37217362 DOI: 10.1016/j.jpedsurg.2023.04.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 04/04/2023] [Accepted: 04/19/2023] [Indexed: 05/24/2023]
Abstract
BACKGROUND Anorectal malformations (ARM) are associated with neurogenic bladder. The traditional surgical ARM repair is a posterior sagittal anorectoplasty (PSARP), which is believed to have a minimal effect on bladder dynamics. However, little is known about the effects of reoperative PSARP (rPSARP) on bladder function. We hypothesized that a high rate of bladder dysfunction existed in this cohort. METHODS We performed a retrospective review of ARM patients undergoing rPSARP at a single institution from 2008 to 2015. Only patients with Urology follow-up were included in our analysis. Data was collected regarding original level of ARM, coexisting spinal anomalies and indications for reoperation. We assessed urodynamic variables and bladder management (voiding, CIC or diverted) before and after rPSARP. RESULTS A total of 172 patients were identified, of which 85 met inclusion criteria with a median follow-up of 23.9 months (IQR, 5.9-43.8 months). Thirty-six patients had spinal cord anomalies. Indications for rPSARP included mislocation (n = 42), posterior urethral diverticulum (PUD; n = 16), stricture (n = 19) and rectal prolapse (n = 8). Within 1 year following rPSARP, 11 patients (12.9%) had a negative change in bladder management, defined as need for beginning intermittent catheterization or undergoing urinary diversion, which increased to 16 patients (18.8%) at last follow-up. Postoperative bladder management changed in rPSARP patients with mislocation (p < 0.0001) and stricture (p 0.005) but not for rectal prolapse (p 0.143). CONCLUSIONS Patients who undergo rPSARP warrant especially close attention for bladder dysfunction as we observed a negative postoperative change in bladder management in 18.8% of our series.

[PMID: 37045715 DOI: 10.1016/j.jpedsurg.2023.02.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/27/2023] [Accepted: 02/08/2023] [Indexed: 02/27/2023]
Abstract
BACKGROUND Registries are important in rare disease research. The Anorectal Malformation Network (ARM-Net) registry is a well-established European patient registry collecting demographic, clinical, and functional outcome data. We assessed the quality of this registry through review of the structure, data elements, collected data, and user experience. MATERIAL AND METHODS Design and data elements were assessed for completeness, consistency, usefulness, accuracy, validity, and comparability. An intra- and inter-user variability study was conducted through monitoring and re-registration of patients. User experience was assessed via a questionnaire on registration, design of registry, and satisfaction. RESULTS We evaluated 119 data elements, of which 107 were utilized and comprised 42 string and 65 numeric elements. A minority (37.0%) of the 2278 included records had complete data, though this improved to 83.5% when follow-up elements were excluded. Intra-observer variability demonstrated 11.7% incongruence, while inter-observer variability was 14.7%. Users were predominantly pediatric surgeons and typically registered patients within 11-30 min. Users did not experience any significant difficulties with data entry and were generally satisfied with the registry, but preferred more longitudinal data and patient-reported outcomes. CONCLUSIONS The ARM-Net registry presents one of the largest ARM cohorts. Although its collected data are valuable, they are susceptible to error and user variability. Continuous evaluations are required to maintain relevant and high-quality data and to achieve long-term sustainability. With the recommendations resulting from this study, we call for rare disease patient registries to take example and aim to continuously improve their data quality to enhance the small, but impactful, field of rare disease research.

Bowel function and associated risk factors at preschool and early childhood age in children with anorectal malformation type rectovestibular fistula: An ARM-Net consortium study. J Pediatr Surg 2022; 57:89-96.

Abstract
BACKGROUND Outcome of patients operated for anorectal malformation (ARM) type rectovestibular fistula (RVF) is generally considered to be good. However, large multi-center studies are scarce, mostly describing pooled outcome of different ARM-types, in adult patients. Therefore, counseling parents concerning the bowel function at early age is challenging. Aim of this study was to evaluate bowel function of RVF-patients at preschool/early childhood age and determine risk factors for poor functional outcome. METHODS A multi-center cohort study was performed. Patient characteristics, associated anomalies, sacral ratio, surgical procedures, post-reconstructive complications, one-year constipation, and Bowel Function Score (BFS) at 4-7 years of follow-up were registered. Groups with below normal (BFS < 17; subgroups 'poor' ≤ 11, and 'fair' 11 < BFS < 17) and good outcome (BFS ≥ 17) were formed. Univariable analyses were performed to detect risk factors for outcome. RESULTS The study included 111 RVF-patients. Median BFS was 16 (range 6-20). The 'below normal' group consisted of 61 patients (55.0%). Overall, we reported soiling, fecal accidents, and constipation in 64.9%, 35.1% and 70.3%, respectively. Bowel management was performed in 23.4% of patients. Risk factors for poor outcome were tethered cord and low sacral ratio, while sacral anomalies, low sacral ratio, prior enterostomy, post-reconstructive complications, and one-year constipation were for being on bowel management. CONCLUSIONS Although median BFS at 4-7 year follow-up is nearly normal, the majority of patients suffers from some degree of soiling and constipation, and almost 25% needs bowel management. Several factors were associated with poor bowel function outcome and bowel management. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE To determine the birth prevalence, maternal risk factors and 5-year survival for isolated and complex anorectal malformations. DESIGN National birth cohort using hospital admission data and death records. SETTING All National Health Service England hospitals. PATIENTS Live-born singletons delivered from 2002 through 2018, with evidence in the first year of life of a diagnosis of an anorectal malformation and repair during a hospital admission, or anorectal malformation recorded on the death certificate. Cases were further classified as isolated or complex depending on the presence of additional anomalies. MAIN OUTCOME MEASURES Birth prevalence of anorectal malformations per 10 000 live births, risk ratios for isolated and complex anorectal malformation by maternal, infant and birth characteristics, and 5-year survival. RESULTS We identified 3325 infants with anorectal malformations among 9 474 147 live-born singletons; 61.7% (n=2050) of cases were complex. Birth prevalence was 3.5 per 10 000 live births (95% CI 3.4 to 3.6). Complex anorectal malformations were associated with maternal age extremes after accounting for other sociodemographic factors. Compared with maternal ages 25-34 years, the risk of complex anorectal malformations was 31% higher for ≥35 years (95% CI 17 to 48) and 13% higher for ≤24 years (95% CI 0 to 27). Among 2376 anorectal malformation cases (n=1450 complex) born from 2002 through 2014, 5-year survival was lower for complex (86.9%; 95% CI 85.1% to 88.5%) than isolated anorectal malformations (98.2%; 95% CI 97.1% to 98.9%). Preterm infants with complex anorectal malformations had the lowest survival (73.4%; 95% CI 68.1% to 78.0%). CONCLUSIONS Differences in maternal risk factors for isolated and complex anorectal malformations may reflect different underlying mechanisms for occurrence. Five-year survival is high but lowest for preterm children with complex anorectal malformations.

Clinical Differentiation between a Normal Anus, Anterior Anus, Congenital Anal Stenosis, and Perineal Fistula: Definitions and Consequences—The ARM-Net Consortium Consensus. CHILDREN 2022; 9:children9060831.

Abstract
In the past, an anteriorly located anus was often misdiagnosed and treated as an anorectal malformation (ARM) with a perineal fistula (PF). The paper aims to define the criteria for a normal anus, an anterior anus (AA) as an anatomic variant, and milder types of ARM such as congenital anal stenosis (CAS) and PF. An extensive literature search was performed by a working group of the ARM-Net Consortium concerning the subject “Normal Anus, AA, and mild ARM”. A consensus on definitions, clinical characteristics, diagnostic management, and treatment modalities was established, and a diagnostic algorithm was proposed. The algorithm enables pediatricians, midwives, gynecologists, and surgeons to make a timely correct diagnosis of any abnormally looking anus and initiate further management if needed. Thus, the routine physical inspection of a newborn should include the inspection of the anus and define its position, relation to the external sphincter, and caliber. A correct diagnosis and use of the presented terminology will avoid misclassifications and allow the initiation of correct management. This will provide a reliable comparison of different therapeutic management and outcomes of these patient cohorts in the future.

Abstract
Anorectal disorders are common in children. They are related to structural and/or functional abnormalities of the anorectum or pelvic floor with a variety of symptoms. Therefore, diagnostic tests to evaluate anorectal function can help to better understand the underlying pathophysiology and aetiology as well as facilitate patient management. During the past decades, substantial efforts have been made to improve anorectal function testing; however, more advanced investigations might lead to difficulties in interpretation. Additionally, a great diversity of equipment and protocols are used among centres, which may lead to heterogeneous interpretation of results. More studies to standardize methods of testing and validate reference values are strongly recommended in children. This review updates on the current indications and the protocol of anorectal manometry.

Abstract
Congenital anomalies of the tubular gastrointestinal tract are an important cause of morbidity not only in infants, but also in children and adults. The gastrointestinal (GI) tract, composed of all three primitive germ layers, develops early during embryogenesis. Two major steps in its development are the formation of the gut tube (giving rise to the foregut, the midgut and the hindgut), and the formation of individual organs with specialized cell types. Formation of an intact and functioning GI tract is under strict control from various molecular pathways. Disruption of any of these crucial mechanisms involved in the cell-fate decision along the dorsoventral, anteroposterior, left-right and radial axes, can lead to numerous congenital anomalies, most of which occur and present in infancy. However, they may run undetected during childhood. Therapy is surgical, which in some cases must be performed urgently, and prognosis depends on early diagnosis and suitable treatment. A precise pathologic macroscopic or microscopic diagnosis is important, not only for the immediate treatment and management of affected individuals, but also for future counselling of the affected individual and their family. This is even more true in cases of multiple anomalies or syndromic patterns. We discuss some of the more frequent or clinically important congenital anomalies of the tubular GI, including atresia's, duplications, intestinal malrotation, Meckel's diverticulum and Hirschsprung's Disease.

Abstract
OBJECTIVE To identify cumulative 5-year healthcare costs and healthcare days in children with anorectal malformation (ARM) and to compare the cumulative 5-year healthcare costs and healthcare days in children with ARM with 3 control cohorts: healthy, premature, and congenital heart disease (CHD). STUDY DESIGN We performed a retrospective case-control study using the Truven MarketScan database of commercial claims encounters between 2008 and 2017. The ARM, CHD, and premature cohorts were identified using a targeted list of International Classification of Diseases 9th or 10th Revision diagnosis and Current Procedural Terminology codes. The healthy cohort included patients without ARM, preterm birth, or CHD. RESULTS We identified 664 children with ARM, 3356 children with heart disease, 63 190 children who were born preterm, and 2947 healthy patients. At 5 years, the total healthcare costs of children with ARM ($273K, 95% CI $168K-$378K) were similar to the premature cohort ($246K, 95% CI $237K-$255K) and lower than the CHD cohort ($466K, 95% CI $401K-$530K, P < .001). Total healthcare days were similar in children with ARM (158 days, 95% CI 117-198) and prematurity (141 days, 95% CI 137-144) but lower than CHD (223 days, 95% CI 197-250, P = .02). In ARM, outpatient care (126 days, 95% CI 93-159) represented the largest contribution to total healthcare days. CONCLUSIONS Children with ARM accumulate similar healthcare costs to children with prematurity and comparable healthcare days to children with CHD and prematurity in the first 5 years of life. Outpatient care represents the majority of healthcare days in children with ARM, identifying this as a target for quality improvement and demonstrating the long-term impact of this condition.

Kurdi M, Moukhtar A, Elkholy M, Alwassia H, Bamehriz M, Khirallah MG. Delayed vs. early enteral feeding after repair of congenital recto-vestibular fistula: The effect on perineal wound healing. Front Pediatr 2022; 10:994249. [PMID: 36683784 PMCID: PMC9846780 DOI: 10.3389/fped.2022.994249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 12/09/2022] [Indexed: 01/06/2023] Open
Abstract
INTRODUCTION congenital Recto vestibular fistula represents the commonest type of anorectal malformation in females. The treatment of this anomaly is mainly approached either through anterior or posterior sagittal ano-rectoplasty approach. Several perioperative factors may affect the outcome. One of major postoperative complications is the occurrence of wound infection. We aimed to study the effect of delayed vs. early enteral feeding on the occurrence of perineal wound infection (PWI) after repair of congenital recto vestibular fistula. PATIENTS AND METHODS Fifty-five infants with recto-vestibular fistula were included. They were managed by single stage anterior sagittal anorectoplasty (ASARP) at an age ≥3 months. Groups A and B included infants who started oral intake on the 6th and 2nd postoperative days respectively. Group A infants were kept on peripheral parenteral nutrition (PPN) during the fasting period. RESULTS Superficial wound infection occurred in three cases in group A while it developed in seven cases in group B. Deep perineal infection occurred in two and five cases in group A and group B respectively. The mean hospital stay was 8 days in group A vs. 13 days in group B when PWI developed. CONCLUSION Delayed enteral feeding with PPN keeps the perineal wound less contaminated with stool. This promoted proper and fast healing with lower incidence of PWI. Also, PPN compensates the catabolic effects of both surgical trauma and fasting during the postoperative period and ensures maintenance of normal levels of essential nutrients that allow for proper healing.

Abstract
PURPOSE The purpose of this study was to compare the postoperative outcomes of neonatal versus delayed repair of rectoperineal and rectovestibular fistulae using a multi-center pediatric colorectal specific database. We hypothesized that the incidence of 30-day postoperative complications is not significantly different between these two surgical treatment strategies. METHODS We performed a retrospective, observational study of the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) database. We included any patient from the database that underwent primary surgical repair of a rectoperineal or rectovestibular fistula. Neonatal repair was defined as occurring within 14 days of birth, and delayed repair as occurring after that period. The primary outcome was the occurrence of postoperative complications within 30 days. RESULTS 164 patients were included in the study (123 rectoperineal, 41 rectovestibular); the majority (81%) were repaired in a delayed fashion. Patients that underwent delayed repair had lower birth weights and were more likely to be female than those that underwent neonatal repair. Wound breakdown/dehiscence was the most common complication in both groups (Delayed 5.3% v. Neonatal, 6.5%). We found no significant difference in the incidence of any postoperative complication between groups (Delayed 6.0 v. Neonatal 6.5%, p = 1.0). CONCLUSION We concluded there was no significant difference in the incidence of 30-day postoperative complications for neonatal versus delayed repair of rectoperineal and rectovestibular fistulae, suggesting that both strategies are safe and may have excellent short-term outcomes in appropriately selected patients.

Abstract
Anorectal malformation with rectovestibular fistula associated with vaginal agenesis is rare. We report on a child in whom this combination was diagnosed at the age of 1 year. After creation of a divided descending colostomy, we chose to leave the rectum-rectovestibular fistula to function as a neovagina, while the sigmoid colon was relocated via modified posterior sagittal anorectoplasty. The colostomy was closed 6 months after the main surgery. After a follow-up of 3 years, the patient is continent for stool and urine. The introitus of the neovagina appears wide and easy to explore. We conclude that our surgical approach may be a good option for these children.

Abstract
PURPOSE The ideal colostomy type indicated for patients with anorectal malformation (ARM) is disputed. The aim of this study was to analyze the clinical factors associated with urinary tract infection (UTI) prior to corrective surgery in male ARM without perineal fistula having undergone diverting enterostomy. METHODS A retrospective review of patients diagnosed with ARM and surgically managed at our center from January 2011 to December 2019 was performed. Logistic regression was used to analyze the association between clinical factors and UTI. RESULTS Eighty boys with ARM without perineal fistula underwent diverting enterostomy and subsequent corrective surgery via laparoscopic-assisted anorectal pull-through. A sigmoid loop colostomy was most often performed (70 patients, 87.5%). Twenty-nine patients (36.3%) were diagnosed with vesicoureteral reflux (VUR), including 14 (48.3%) with febrile UTIs. Six patients had other concomitant genitourinary anomalies excluding VUR. Multivariate logistic regression analysis revealed the presence of VUR as the only independent factor associated with the occurrence of febrile UTI (OR 17.3, 95% CI 3.51-85.26, p < 0.001). CONCLUSION The development of UTI in newborn males with ARM is associated with the presence of VUR, regardless of stoma type. Voiding cystourethrography should be considered in patients with ARM for early diagnosis of VUR and subsequent antibiotic prophylaxis.

Abstract
INTRODUCTION Published studies based on Krickenbeck classification of anorectal malformations (ARMs) are still insufficient to assess the global as well as regional relative incidence of different ARM subtypes, gender distribution, and associated anomalies. The primary purpose of this study was to provide an estimate of those in Global Initiative for Children's Surgery (GICS) research group. MATERIALS AND METHODS We collected ARM data prospectively for 1 year from four institutes of different geographic locations. A total of 342 patients were included in this study (195, 126, 11, and 10 from Bangladesh, Iran, Papua New Guinea, and Oxford, United Kingdom, respectively). RESULTS Overall male to female ratio was 1:1. The most frequent ARM subtype was perineal fistula (23.7% = 81/342). About 48.5% (166/342) patients had at least one associated anomaly. Cardiac and genitourinary systems were the most commonly affected systems, 31.6% (108/342) and 18.4% (63/342), respectively. These organ-systems were followed by anomalies of vertebral/spinal (9.9% = 34/342), musculoskeletal (4.4% = 15/342), and gastrointestinal/abdominal (3.2% = 11/342) systems. Rectovesical fistula had the highest percentage (96.4% = 27/28) of associated anomalies. About 18.1% (62/342) patients had multiple anomalies. ARMs (both isolated and with associated anomalies) occurred equally in males and females. Comparison between patients from Bangladesh and Iran showed differences in relative incidence in ARM subtypes. In addition, Iranian patient group had higher percentage of associated anomalies compared with Bangladeshi (73 vs. 35.4%). CONCLUSION Our study provides important insights about ARM subtypes, gender distribution and associated anomalies based on Krickenbeck classification especially from Bangladesh and Iran.

Abstract
Introduction To our knowledge, there are no studies to date that have compared patients with isolated anorectal malformation (ARM) to patients with ARM and an associated genitourinary (GU) malformation despite a possible etiological difference between these two entities. We examined the differences in maternal and prenatal exposures and comorbidities between patients with isolated ARM and patients with ARM and associated GU malformations. Materials and methods A retrospective cohort study of children with ARM, enrolled in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC) between February 2017 and October 2019, was performed comparing those with isolated ARM to those with ARM and associated GU anomalies (GU +/- additional anomalies) as well as to those with ARM and a GU anomaly with no anomaly of any other system (GU-only). We compared the prevalence of prematurity, family history of colorectal disorders, as well as maternal and prenatal comorbidities and exposures between these two cohorts and the isolated ARM cohort. Results A total of 505 patients (117 with isolated ARM and 388 with ARM and associated GU anomalies) were enrolled. Of the 388 patients with ARM and associated GU anomalies, 48 had an ARM with a GU anomaly without an anomaly in any other system. There was an increased prevalence of premature births in the GU +/- additional anomalies cohort compared to the isolated ARM cohort (27 vs 14%, p=0.003). This difference was not seen in the GU-only cohort. There was no difference between the cohorts regarding prevalence of family history of ARM or maternal and prenatal comorbidities or exposures. Conclusions Patients with an ARM and an associated GU anomaly with or without other congenital anomalies are more likely to be born prematurely compared to patients with an isolated ARM. Parents of these children should be counseled on this increased risk.

Inter- and Intraobserver Variation in the Assessment of Preoperative Colostograms in Male Anorectal Malformations: An ARM-Net Consortium Survey. Front Pediatr 2020; 8:571.

Abstract
Aim: Male patients with anorectal malformations (ARM) are classified according to presence and level of the recto-urinary fistula. This is traditionally established by a preoperative high-pressure distal colostogram that may be variably interpreted by different surgeons. The aim of this study was to evaluate the inter- and intraobserver variation in the assessment by pediatric surgeons of preoperative colostograms with respect to the level of the recto-urinary fistula. Materials and Methods: Sixteen pediatric surgeons from 14 European centers belonging to the ARM-Net Consortium twice scored 130 images of distal colostograms taken in sagittal projection at a median age of 66 days of life (range: 4-1,106 days). Surgeons were asked to classify the fistula in bulbar, prostatic, bladder-neck, no fistula, and "unclear anatomy" example. Their assessments were compared with the intraoperative findings (kappa) for two scoring rounds with an interval of 6 months (intraobserver variation). Agreement among the surgeons' scores (interobserver variation) was also calculated using Krippendorff's alpha. A kappa over 0.75 is considered excellent, between 0.40 and 0.75 fair to good, and below 0.40 poor. Surgeons were asked to score the images in "poor" and "good" quality and to provide their years of experience in ARM treatment. Results: Agreement between the image-based rating of surgeons and the intraoperative findings ranges from 0.06 to 0.45 (mean 0.31). Interobserver variation is higher (Krippendorff's alpha between 0.40 and 0.45). Years of experience in ARM treatment does not seem to influence the scoring. The mean intraobserver variation between the two rounds is 0.64. Overall, the quality of the images is considered poor. Images categorized as having a good quality result in a statistically significant higher kappa (mean: 0.36 and 0.37 in the first and second round, respectively) than in the group of bad-quality images (mean: 0.25 and 0.23, respectively). Conclusions: There is poor agreement among experienced pediatric colorectal surgeons on preoperative colostograms. Techniques and analyses of images need to be improved in order to generate a homogeneous series of patients and make comparison of outcomes reliable.

Abstract
BACKGROUND Anorectal malformations (ARMs) are common congenital malformations of the terminal digestive tract, but little is known regarding their pathogenesis. Aberrant cell proliferation/apoptosis are believed to be involved in ARMs. However, there are no studies on proliferation/apoptosis-related genes. PURPOSE We aimed to investigate the spatiotemporal expression patterns of two proliferation/apoptosis-related genes (MYC proto-oncogene and tumor protein p53) and explore their potential functions in the hindguts of ethylene thiourea-induced ARMs rat fetuses. METHODS MYC and p53 expression was evaluated using immunohistochemical staining, western blotting, and quantitative real-time polymerase chain reaction (RT-qPCR). Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) and p53 costaining were performed to assay the colocalization of apoptotic and p53-expressing cells. RESULTS Rat fetuses with ARMs displayed fusion failure of the urogenital septum and cloacal membrane. In the control group, MYC was persistently expressed from gestational day (GD)14 to GD16 and distributed throughout the hindgut, while p53 was weakly detected in the terminal segment of the urethra and hindgut; in the ARMs group, MYC expression was obviously reduced, while p53 was widely and highly expressed in the urethra and hindgut. Western blotting and RT-qPCR confirmed the decrease in MYC and increase in p53 expression in ARMs. TUNEL and p53 co-staining revealed considerable overlap between apoptotic and p53-expressing cells. CONCLUSION The expression patterns of c-myc and p53 were disrupted in ARMs rat embryos, and the downregulation of c-myc and upregulation of p53 might be related to the development of ARMs at the key time points of ARMs morphogenesis.

Abstract
BACKGROUND Anorectal malformations (ARMs) are the most frequent congenital intestinal anomalies. The aim of this study was to describe the epidemiology of anorectal defects between 1981 and 2014 and to evaluate patients' survival. METHODS A population-based study using data collected by an Italian, regional registry of birth defects and by the local Pediatric Surgery Units. RESULTS A total of 428 individuals with ARM were identified, with an overall prevalence of 3.09 per 10,000 births. Characteristics associated with decreased survival were low birth weight (<2500 g) (HR 6.4; 95% CI, 2.3-17.9), the presence of two or more additional major defects (HR 7.9; 95% CI, 2.2-27.8), and birth before year 2000 (HR 4.7; 95% CI, 1.8-11.8). The 10-year survival probability was 100% for individuals with isolated ARM, regardless of their birth weight. Survival of patients with non-isolated ARM varied according to their year of birth and birth weight: 73.3% (≥2500 g) and 23.8% (<2500 g) in children born before 2000; 97.9% (≥2500 g) and 68.8% (<2500 g) in children born after year 2000. CONCLUSIONS This study found a significant improvement in the survival of individuals with anorectal malformations over the past decades and identified the strongest predictors of mortality.

Abstract
PURPOSE Since pediatric surgeons aim to follow their patients with anorectal malformations (ARM) into adulthood the aim of this study was to investigate how pediatric surgeons deal with sexual issues related to ARM. METHODS In 2018, a questionnaire was developed by the working group "Follow-up and sexuality" of the ARM-Net consortium and sent to all consortium-linked pediatric surgeons from 31 European pediatric surgical centers. Obtained data were statistically analyzed. RESULTS Twenty-eight of 37 pediatric surgeons (18 males/10 females) answered the questionnaire. The majority of pediatric surgeons (82%) think they should talk about sexual issues with their patient. More than 50% of pediatric surgeons do not feel at all or only moderately confident discussing the topic of sexuality. Most pediatric surgeons require more support (96%) and wish to be trained in sexuality and sexual issues (78%) to feel confident towards their ARM-patients/parents. For optimal care, sexual issues with ARM-patients should be managed by a multidisciplinary team. CONCLUSIONS Pediatric surgeons feel that sexuality is an important issue for their ARM-patients, which they are primarily responsible of but should be managed in concert with a multidisciplinary team. A training in sexuality is wished to feel more confident about this specific issue.

The impact of perioperative care on complications and short term outcome in ARM type rectovestibular fistula: An ARM-Net consortium study. J Pediatr Surg 2019; 54:1595-1600.

Abstract
BACKGROUND The impact of perioperative care interventions on postreconstructive complications and short-term colorectal outcome in patients with anorectal malformation (ARM) type rectovestibular fistula is unknown. METHODS An ARM-Net consortium multicenter retrospective cohort study was performed including 165 patients with a rectovestibular fistula. Patient characteristics, perioperative care interventions, timing of reconstruction, postreconstructive complications and the colorectal outcome at one year of follow-up were registered. RESULTS Overall complications were seen in 26.8% of the patients, of which 41% were regarded major. Differences in presence of enterostomy, timing of reconstruction, mechanical bowel preparation, antibiotic prophylaxis and postoperative feeding regimen had no impact on the occurrence of overall complications. However, mechanical bowel preparation, antibiotic prophylaxis ≥48 h and postoperative nil by mouth showed a significant reduction in major complications. The lowest rate of major complications was found in the group having these three interventions combined (5.9%). Multivariate analyses did not show independent significant results of any of the perioperative care interventions owing to center-specific combinations. At one year follow-up, half of the patients experienced constipation and this was significantly higher among those with preoperative mechanical bowel preparation. CONCLUSIONS Differences in perioperative care interventions do not seem to impact the incidence of overall complications in a large cohort of European rectovestibular fistula-patients. Mechanical bowel preparation, antibiotic prophylaxis ≥48 h, and postoperative nil by mouth showed the least major complications. Independency could not be established owing to center-specific combinations of interventions. TYPE OF STUDY Treatment study. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION Anorectal malformations (ARM) are rare congenital malformations, resulting from disturbed hindgut development. A genetic etiology has been suggested, but evidence for the involvement of specific genes is scarce. We evaluated the contribution of rare and low-frequency coding variants in ARM etiology, assuming a multifactorial model. METHODS We analyzed 568 Caucasian ARM patients and 1,860 population-based controls using the Illumina HumanExome Beadchip array, which contains >240,000 rare and low-frequency coding variants. GenomeStudio clustering and calling was followed by re-calling of 'no-calls' using zCall for patients and controls simultaneously. Single variant and gene-based analyses were performed to identify statistically significant associations, applying Bonferroni correction. Following an extra quality control step, candidate variants were selected for validation using Sanger sequencing. RESULTS When we applied a MAF of ≥1.0%, no variants or genes showed statistically significant associations with ARM. Using a MAF cut-off at 0.4%, 13 variants initially reached statistical significance, but had to be discarded upon further inspection: ten variants represented calling errors of the software, while the minor alleles of the remaining three variants were not confirmed by Sanger sequencing. CONCLUSION Our results show that rare and low-frequency coding variants with large effect sizes, present on the exome chip do not contribute to ARM etiology.

Abstract
Background Quantitative real-time polymerase chain reaction (RT-qPCR) is a sensitive method for quantifying mRNA abundance. With relative expression analysis, however, reliable data output is dependent on stably expressed reference genes across the samples being studied. In anorectal malformations (ARMs), there is limited data on the selection of appropriate reference genes. Purpose This study was aimed to investigate the optimal reference genes for PCR in ARM rat models. Methods We selected 15 commonly used reference genes (Rps18, Actb, B2m, Gapdh, Ppia, Hprt1, Pgk1, Ywhaz, Tbp, Ubc, Rps16, Rpl13a, Rplp1, Sdha, and Hmbs) as candidate reference genes and detected their mRNA expression in ARM samples by RT-qPCR. The expression stability and variability of these transcripts were subsequently evaluated using four methods (geNorm, NormFinder, comparative ΔCt, and BestKeeper). Results The abundance of the candidate reference genes was qualified by RT-qPCR and the cycle threshold (Ct) values ranged between 14.07 (Rplp1) and 21.89 (Sdha). In the overall candidate genes, different variations existed across the different algorithms. A comprehensive analysis revealed that Rpl13a ranked first among the relatively stable genes, followed by Ywhaz, Rps18, Sdha, and Hmbs. Conclusions The most stable reference genes for RT-qPCR were Rpl13a, Ywhaz, and Rps18 in ETU-induced ARMs in rat fetus. This study provided a foundation for reference gene selection for future gene expression analyses.

Abstract
BACKGROUND/PURPOSE Anorectal malformation (ARM) is a common condition. Owing to scarcity of pediatric surgery services in Uganda, however, relatively little is known about this condition. METHODS This was a retrospective review of medical records of all patients admitted to Mbarara Regional Referral Hospital (MRRH) from January 2014 to May 2016. MRRH serves 3-8 million people in southwest Uganda. We also enrolled patients prospectively from June 2016 to December 2016. RESULTS 78 patients were enrolled in the study. 63.38% had delayed diagnosis (presenting >48 h after birth), and most of these were self-referrals from home. The most common malformation was a vestibular fistula. Associated congenital anomalies were seen in 20% of patients, and this was associated with increased mortality. These anomalies included limb, eye, ear and genitourinary anomalies as well as ventricular septal defects, patent ductus arteriosus, spina bifida and tracheoesophageal fistula. Posterior sagittal anorectoplasty (PSARP) was the definitive surgery used. It was performed in 58.97% of the patients. Median age of patients who underwent PSARP was 11 months. 73.91% of PSARP patients had their colostomies closed and 62.5% of these who were ≥3 years old had good continence outcomes. Overall mortality rate was 8.97%. CONCLUSION The majority of patients are diagnosed late. Vestibular fistula is the overall most common type of ARM. In males, however, rectourethral fistula is the most common type. Definitive surgery at MRRH is performed late. Continence outcomes are good and comparable to other countries with more resources.

Abstract
BACKGROUND Chronic respiratory diseases and use of antiasthmatic medication during pregnancy may both play a role in the etiology of congenital anorectal malformations (ARM). However, it is unclear, whether the medication use or the underlying condition would be responsible. Therefore, our aim was to unravel the role of maternal chronic respiratory diseases from that of antiasthmatic medication in the etiology of ARM. METHODS We obtained 412 ARM patients and 2,137 population-based controls from the Dutch AGORA data- and biobank. We used maternal questionnaires and follow-up telephone interviews to obtain information on chronic respiratory diseases, antiasthmatic medication use, and potential confounders. Multivariable logistic regression analyses were performed to estimate odds ratios (ORs) with 95% confidence intervals (95% CI). RESULTS We observed higher risk estimates among women with chronic respiratory diseases with and without medication use (1.4 [0.8-2.7] and 2.0 [0.8-5.0]), both in comparison to women without a chronic respiratory disease and without medication use. Furthermore, increased ORs of ARM were found for women using rescue medication (2.4 [0.8-7.3]) or a combination of maintenance and rescue medication (2.5 [0.9-6.7]). In addition, increased risk estimates were observed for women having nonallergic triggers (2.5 [1.0-6.3]) or experiencing exacerbations during the periconceptional period (3.5 [1.4-8.6]). CONCLUSIONS Although the 95% CIs of most associations include the null value, the risk estimates all point towards an association between uncontrolled chronic respiratory disease, instead of antiasthmatic medication use, with ARM in offspring. Further in-depth studies towards mechanisms of this newly identified risk factor are warranted.

Abstract
Anorectal malformations (ARMs) are one of the most common congenital malformations of the digestive tract; however, the pathogenesis of this disease remains to be fully elucidated. MicroRNAs (miRNAs) are important in gastrointestinal development and may be involved in the pathogenesis of ARMs. The present study aimed to profile miRNAs and examine their potential functions in rats with ethylenethiourea (ETU)-induced ARMs. Pregnant Wistar rats (n=36) were divided randomly into ETU-treated and control groups. The rats in the ETU-treated group were gavage-fed 1% ETU (125 mg/kg) on gestational day 10 (GD10), whereas the control group rats received a corresponding dose of saline. Embryos were harvested by cesarean section on GD14, GD15 and GD16. Hindgut tissue was isolated from the fetuses for RNA extraction and microarray analysis, followed by bioinformatics analysis and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) validation. Overall, 38 miRNAs were differentially expressed (all upregulated) on GD14, 49 (32 upregulated and 17 downregulated) on GD15, and 42 (all upregulated) on GD16 in the ARM group compared with the normal group. The top 18 miRNAs with |log2(fold change)| >4.25 were selected for further bioinformatics analysis. Among these miRNAs, five were differentially expressed at two time-points and were involved in ARM-associated signaling pathways. The RT-qPCR analysis revealed that three miRNA (miR), miR-125b-2-3p, miR-92a-2-5p and miR-99a-5p, were significantly differentially expressed in rats with ARMs compared with the normal group. In conclusion, the results suggested that the differential expression of miR-125b-2-3p, miR-92a-2-5p and miR-99a-5p during key time-points of anorectal formation in rats may have functions in the pathogenesis of ARM.

[PMID: 29198537 DOI: 10.1016/j.jpeds.2017.10.010] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2017] [Revised: 09/25/2017] [Accepted: 10/11/2017] [Indexed: 10/18/2022]
Abstract
OBJECTIVE To determine nationwide prevalence and healthcare utilization in children with anorectal malformations and associated anomalies over a 6-year period. STUDY DESIGN We used the Kids' Inpatient Database for the years 2006, 2009, and 2012 for data collection. International Classification of Diseases, Ninth Revision codes were used to identify patients with anorectal malformations and associated anomalies. RESULTS A total of 2396 children <2 years of age with anorectal malformations were identified using weighted analysis; 54.3% of subjects were male. The ethnic subgroups were 40.1% white, 23.6% Hispanic, 9.3% African American, and 27% other ethnicity. Other congenital anomalies were reported in 80% of anorectal malformations and were closely associated with increased length of stay and costs. A genetic disorder was identified in 14.1% of the sample. Urogenital anomalies were present in 38.5%, heart anomalies in 21.2%, and 8.6% had vertebral anomalies, anal atresia, cardiac defects, tracheoesophageal fistula and/or esophageal atresia, renal anomalies, and limb defects association. Anorectal malformations with other anomalies including vertebral anomalies, anal atresia, cardiac defects, tracheoesophageal fistula and/or esophageal atresia, renal anomalies, and limb defects association incurred significant hospital charges when compared with anorectal malformations alone. The average annual healthcare expenditure for surgical correction of anorectal malformations and associated anomalies for the 3 years was US $45.5 million. CONCLUSIONS This large, major nationally representative study shows that majority of children with anorectal malformations have additional congenital anomalies that deserve prompt recognition. The high complexity and need for lifelong multidisciplinary management is associated with substantial healthcare expenditure. This information complements future healthcare resource allocation and planning for management of children with anorectal malformations.

Abstract
PURPOSE This study was undertaken to investigate the types of anorectal malformations (ARM), incidence of associated abnormalities and investigative methods used in patients treated at Red Cross War Memorial Children's Hospital and to determine whether these are in keeping with recent literature. Mortality rates were also reviewed. METHODS A retrospective review of patients with ARM between 1993 and 2016 was undertaken. Clinical notes were reviewed and correlated with radiology and cardiac databases. Abnormalities were grouped according to genitourinary, musculoskeletal, gastrointestinal and cardiovascular systems. The data were separated into three periods to ascertain whether the workup strategy had changed over the years. RESULTS A total of 282 patients were included. There were 134 (47.5%) high and 116 (41.1%) low lesions and unspecified in 32 (11.3%) patients. There were 59 (20.9%) vestibular fistulae, 46 (16.3%) combined rectourethral fistulae (rectoprostatic, rectobulbar and unspecified rectourethral) and 42 (14.9%) perineal fistulae. Associated abnormalities were detected in 152/221 (69%). Abnormalities were: Genitourinary 88/204 (43.1%), musculoskeletal 80/188 (42.5%), cardiac 44/218 (20.1%) and gastrointestinal 12/216 (5.6%). Twenty patients demised. CONCLUSION Vestibular fistulae were most common followed by rectourethral and perineal fistulae. Musculoskeletal and genitourinary abnormalities were the most common associated findings. The mortality rate was 7% and cardiac lesions contributed to mortality. As knowledge of ARM improved, so has awareness of associated malformations. This has led to improved, more active workup, in keeping with the latest literature.

Abstract
OBJECTIVE To determine whether the frequency and severity of congenital anorectal malformations (CARMs) differs by sex. STUDY DESIGN We included 129 patients (0-319 weeks old) diagnosed with CARMs, who had been referred to our Department of Pediatric Surgery between 2004 and 2013. Rectoperineal and rectovestibular fistulas were classified as mild CARMs, all others as severe. If a patient was diagnosed with CARM within 48 hours after birth, this was considered an early diagnosis, all others as late. RESULTS Seventy-five (58%) girls and 54 (42%) boys were diagnosed with different forms of CARM. More patients had mild rather than severe forms of CARM (67% and 33%, respectively, P <.001). We found that 89% of girls had a mild form of CARM, whereas 65% of boys had severe forms (P <.001). All severe forms were diagnosed early, whereas 54% mild forms were diagnosed early and 46% were diagnosed late. CONCLUSIONS Girls more often have mild forms of CARM, whereas boys more often have severe forms. Overall, the distribution across the sexes is equal. Because chronic constipation can be the only symptom of mild CARMs, it often requires more time to diagnose than severe forms. Many women are, therefore, diagnosed with CARMs at an older age, or they may go undiagnosed altogether. Subsequently, these women have a greater risk of full rupture during vaginal delivery.

Patients with anorectal malformation and upper limb anomalies: genetic evaluation is warranted. Eur J Pediatr 2016; 175:489-97.

Abstract
UNLABELLED The objective of this study was to compare the prevalence of genetic disorders in anorectal malformation (ARM) patients with upper limb anomalies to that in ARM patients with other associated anomalies. A retrospective case study was performed in two pediatric surgery centers. All patients born between 1990 and 2012 were included. VACTERL (vertebral defects (V), anal atresia (A), cardiac malformations (C), tracheoesophageal fistula with esophageal atresia (TE), renal dysplasia (R), and limb anomalies (L)) was defined as at least three components present. We included 700 ARM patients: 219 patients (31 %) had isolated ARM, 43 patients (6 %) had a major upper limb anomaly, and 438 patients (63 %) had other associated anomalies. The most prevalent upper limb anomalies were radial dysplasia (n = 12) and hypoplastic thumb (n = 11). Ten of the 43 patients (23 %) with an upper limb anomaly were diagnosed with a genetic disorder-nine also met the VACTERL criteria-vs. 9 % of ARM patients with other anomalies (p = 0.004, chi-squared test). CONCLUSION Genetic disorders are twice as frequently diagnosed in ARM patients with upper limb anomalies than in those with other anomalies. As they also frequently meet the VACTERL criteria, it is important to consider VACTERL as a diagnosis per exclusionem. Genetic counseling is certainly warranted in these patients. WHAT IS KNOWN • Anorectal malformations (ARMs) often co-occur with other congenital anomalies, including upper limb anomalies, mainly of pre-axial origin. • Co-occurrence of ARMs and upper limb anomalies is seen in disorders such as Townes-Brocks syndrome, Fanconi anemia, and VACTERL association. What is New: • ARM patients with a major upper limb anomaly-with or without other congenital anomalies-have a twofold greater chance of a genetic disorder than have non-isolated ARM patients without upper limb anomalies. • Not all upper limb anomalies in ARM patients are part of the VACTERL association; a workup for genetic evaluation is proposed.

Abstract
PURPOSE The aim of this study was to compare the frequency and nature of VACTERL associations between children who underwent surgery for esophageal atresia/tracheoesophageal fistula (EA/TEF) and anorectal malformation (ARM). METHODS We identified all children who underwent surgery for EA/TEF and/or ARM at hospitals participating in the Pediatric Health Information System (PHIS) database between 2004 and 2012. PHIS is an administrative database of free-standing children's hospitals managed by the Child Health Corporation of America (Overland Park, KS) that contains patient-level care data from 43 hospitals. The complete records of patients in this cohort were cross-referenced for diagnoses of vertebral, cardiac, renal and limb anomalies. RESULTS 2689 children underwent repair of esophageal atresia. Mean gestational age was 36.5±3.2weeks and mean birth weight was 2536.0±758.7g. Associated VACTERL diagnoses included vertebral anomaly in 686 (25.5%), ARM in 312 (11.6%), congenital heart disease in 1588 (59.1%), renal disease in 587 (21.8%) and limb defect in 192 (7.1%). 899 (33.4%) had 3 or more anomalies and met criteria for a VACTERL diagnosis. 4962 children underwent repair of ARM. Mean gestational age was 37.4±2.7weeks and mean birth weight was 2895.2±765.1g. Associated VACTERL diagnoses included vertebral anomaly in 1562 (31.5%), congenital heart disease in 2007 (40.4%), EA/TEF in 348 (7.0%), renal disease in 1723 (34.7%) and limb defect in 359 (7.2%). 1795 (36.2%) had 3 or more anomalies and met criteria for a VACTERL diagnosis. CONCLUSION VACTERL associations are relatively common in children with EA/TEF and ARM and occur in specific clusters, with cardiac disease more common in EA/TEF and spinal and renal/urinary anomalies more common in ARM.

Abstract
PURPOSE Aim of study was to evaluate the differences in incidence and presentation of anorectal malformations (ARMs) between selected Pediatric Surgery Divisions in the Republic of South Africa (ZAR) and Italy. METHODS A retrospective cohort study involved analysis of clinical records of patients with ARM born between 2005 and 2012. Type of ARM, maternal age, birth weight, gestational age, presence of associated anomalies and delayed diagnosis were analyzed. RESULTS 335 patients were included in this study. Of note, statistically significant differences between the African and European patient groups were observed in a male predominance in the ZAR patient population. In addition, female recto-perineal fistulas were diagnosed in significantly more Italian patients than in ZAR. Furthermore, a more advanced maternal age and a lower gestational age was noted in the European cohort with a minimal delay in initial diagnosis as opposed to the African counterpart. Both centers reported recto-perineal fistula as the most common malformation in male patients. CONCLUSION With the exception of perineal fistulas in females, the incidence of specific subtypes of ARMs was similar in the two groups. This may be of importance when extrapolating European study conclusion to the South African setting.

Abstract
The repair of cloacal malformations is most often performed using a posterior sagittal anorecto-vagino-urethroplasty (PSARVUP) or total urogenital mobilization (TUM) with or without laparotomy. The aim of this study was to systematically review the frequency and type of postoperative complication seen after cloacal repair as reported in the literature. A systematic literature search was conducted according to preferred reporting items for systematic reviews and meta-analyses guidelines (PRISMA). Eight records were eligible for this study which were qualitatively analyzed according to the Rangel score. Overall complication rates reported in included studies ranged from 0 to 57 %. After meta-analysis of data, postoperative complications were seen in 99 of 327 patients (30 %). The most common reported complications were recurrent or persistent fistula (n = 29, 10 %) and rectal prolapse (n = 27, 10 %). In the PSARVUP group, the complication rate was 40 % and in the TUM group 30 % (p = 0.205). This systematic review shows that postoperative complications after cloacal repair are seen in 30 % of the patients. The complication rates after PSARVUP and TUM were not significantly different. Standardization in reporting of surgical complications would inform further development of surgical approaches. Other techniques aiming to lower postoperative complication rates may also deserve consideration.

Abstract
The ARM-Net (anorectal malformation network) consortium held a consensus meeting in which the classification of ARM and preoperative workup were evaluated with the aim of improving monitoring of treatment and outcome. The Krickenbeck classification of ARM and preoperative workup suggested by Levitt and Peña, used as a template, were discussed, and a collaborative consensus was achieved. The Krickenbeck classification is appropriate in describing ARM for clinical use. The preoperative workup was slightly modified. In males with a visible fistula, no cross-table lateral X-ray is needed and an anoplasty or (mini-) posterior sagittal anorectoplasty can directly be performed. In females with a small vestibular fistula (Hegar size <5 mm), a primary repair or colostomy is recommended; the repair may be delayed if the fistula admits a Hegar size >5 mm, and in the meantime, gentle painless dilatations can be performed. In both male and female perineal fistula and either a low birth weight (<2,000 g) or severe associated congenital anomalies, prolonged preoperative painless dilatations might be indicated to decrease perioperative morbidity caused by general anesthesia. The Krickenbeck classification is appropriate in describing ARM for clinical use. Some minor modifications to the preoperative workup by Levitt and Peña have been introduced in order to refine terminology and establish a comprehensive preoperative workup.

Abstract
Background. Anorectal malformations (ARMs) are extremely rare and are usually identified neonatally. It is unusual for these cases to present in the postmenopausal period. This case report describes a postmenopausal patient with ARM and rectovaginal hemorrhage. Case. An 86-year-old, gravida 11, para 9, presented to the emergency department complaining of profuse postmenopausal vaginal bleeding. Her gynecologic history was significant only for an unclear history of an anal abnormality that was noted at birth. Speculum examination revealed profuse rectal bleeding from a rectovestibular fistula exterior to her hymenal ring. Colonoscopic examination revealed severe diverticular disease. Conclusion. This patient was born with an imperforate anus which resolved as rectovestibular fistula and ectopic anus. This case presents a rare clinical circumstance which integrates the fields of obstetrics, gynecology, gastroenterology, and embryology alike.

Abstract
Like all modern medical therapy, neonatal surgery is founded on clinical research, well-tried clinical practice and basic scientific research. Likewise, modern neonatal surgery strives increasingly for evidence-based management and practice. The very nature of neonatal and pediatric surgery renders associated research challenging because of the rarity and small numbers of surgical disorders and varying resources in different countries and institutions and consequently only a few well-designed trials on truly important issues in neonatal surgical treatment have been performed. This article highlights the research methods by which valid evidence-based research data is obtained in observational studies, randomized controlled trials, and meta-analyses. The problem of small numbers of patients may be overcome by multi-center trials, meta-analyses, and networking. Consideration is also given on the quality and the validity of the study data as well as ethical issues in neonatal surgical research.

Abstract
PURPOSE The presence of esophageal atresia (EA) in patients with an anorectal malformation (ARM) is well known. The purpose of this work is to find out the most common type of ARM associated to EA and the functional prognostic implication of this association, which has not been described in previous publications. METHODS We reviewed our database for demographic, functional, and associated anomalies data in our patients with EA and ARM, and then compared them with those of our general series of ARM without esophageal atresia. RESULTS Out of 1,995 ARM patients, 167 had a concomitant EA (8.3 %). Prostatic fistula was the most common type of defect in the male EA patients (45.9 %) and cloacas were on the female group (57.9 %). EA patients had worse bowel (47 vs. 67 %) and urinary control (56.6 vs. 79.4 %) when compared to the general series (GS). Functional prognosis was significantly worse in cloacas and in patients subjected to re-operations (p < 0.001). EA patients had a 0.52 average sacral ratio and in the GS was 0.65 (p < 0.001). EA patients had a significantly higher incidence of tethered cord (32.3 vs. 17.6 %), cardiac anomalies (32.3 vs. 22.5 %) including VSD (12.5 vs. 4.5 %), hydronephrosis (36.5 vs. 15.4 %), absent kidney (26.3 vs. 10.5 %), duodenal atresia (7.7 vs. 1.7 %), vertebral anomalies (28.1 vs. 14 %), extremity defects (11.3 vs. 3.1 %), tracheal anomalies (6.5 vs. 0.4 %), and developmental delay (5.9 vs. 1.4 %). CONCLUSIONS The presence of esophageal atresia in ARM patients has a significant, probably coincidental, impact on bowel and urinary control. This association is also related with worse types of ARM defects and with more severe associated anomalies. This association should increase the awareness on the provider in terms of what to expect on functional prognosis and a throughout search for associated anomalies.

Abstract
INTRODUCTION Patients with a cloacal malformation generally undergo reconstructive surgery within the first years of life. However, the ideal age for surgery has rarely been mentioned. The aim of this study was to report differences in outcome between early (<6 months) and late repair of cloacal malformations. METHODS Charts of patients with a cloacal malformation treated in 5 pediatric surgical centers between 1985 and 2009 were retrospectively studied for associated anomalies, postoperative complications, and colorectal and urological outcome. RESULTS Forty-two patients were eligible for this study, giving a mean exposure of less than 1 patient yearly per center. Forty-five percent of the patients had a short common channel (>3 cm), and 14% had a long common channel. Length of common channel was missing in 41% of the patients. Median age of the cloacal reconstruction was 9 months (range 1-121 months). Twelve patients (29%) underwent an early surgical repair (within the first 6 months of age; median 3 months), and 30 (71%) patients underwent a late repair (after 6 months of age; median 14 months). Eighteen postoperative complications (<30 days) had been documented in 15 patients (35%), with significant more perineal wound dehiscences in patients with an early repair (42% vs. 10%, p=0.031). There were no differences in complication rate between patients with short and long common channels. Mean follow-up was 142 months (range 15-289). At the last follow-up, 10 patients (24%) had voluntary bowel movements. Fourteen patients (33%) had complaints of soiling, 25 (60%) were constipated, with no differences between the early and late repair groups. Patients in the late repair group as well as the group of patients with a short common channel were more frequently able to void spontaneously. CONCLUSIONS Postoperative complications are common in patients with cloacal malformations. Early repair is associated with more wound dehiscences, however, without affecting long-term functional outcome. All centers had limited annual exposure of less than 1 patient. In these clinical settings, ideal age of cloacal reconstruction seems to be between 6 and 12 months. In general, centralized care for these complex malformations may be the crucial factor for reducing postoperative complications and better long-term outcome.
