RESUMO
BACKGROUND: Our study aimed to compare the clinical outcomes and cost-efficiency of antibiotic management versus laparoscopic appendectomy for acute uncomplicated appendicitis (AUA) in children during the COVID-19 pandemic when resources were limited and transmission risks uncertain. METHOD: In this prospective comparative cohort study, we analyzed the data of 139 children diagnosed with AUA meeting the following inclusion criteria: 5-18 years of age, symptoms duration of ≤ 48 h, appendix diameter ≤ 11 mm and no appendicolith. Treatment outcomes between non-operative management group (78/139) and upfront laparoscopic appendectomy group (61/139) were compared. Antibiotic regimes were intravenous ceftriaxone/metronidazole or amoxicillin/clavulanic acid for 48 h, followed by oral antibiotics to complete total 10-days course. RESULTS: 8/78 (10.3%) children had early failure (within 48 h) requiring appendectomy. 17/70 (24.3%) patients experienced late recurrence within mean follow-up time of 16.2 ± 4.7 months. There were no statistical differences in peri-operative complications, negative appendicectomy rate, and incidence of perforation and hospitalization duration between antibiotic and surgical treatment groups. Cost per patient in upfront surgical group was significantly higher ($6208.5 ± 5284.0) than antibiotic group ($3588.6 ± 3829.8; p = 0.001). CONCLUSION: Despite 24.3% risk of recurrence of appendicitis in 16.2 ± 4.7 months, antibiotic therapy for AUA appears to be a safe and cost-effective alternative to upfront appendectomy.

Purpose: This study aims to compare the outcomes of extravesical (EVUR) and intravesical (IVUR) ureteric reimplantation for primary vesicoureteral reflux (VUR) via systematic review and meta-analysis. Methods: Literature review from Medline, Embase, and Cochrane since inception to March 2022 was performed. Meta-analysis was conducted on eligible randomized controlled trials (RCT) and observational cohort studies (OCS) comparing outcomes between EVUR and IVUR. Results: Twelve studies were included, comprising 577 patients (778 ureters) operated by EVUR and 395 patients (635 ureters) by IVUR. Pre-operative VUR grade, postoperative VUR persistence and hydronephrosis was not statistically significant. EVUR had shorter operative time [mean differences (MD) -22.91 min; 95% confidence interval (CI), -44.53 to -1.30, P = 0.04] and hospital stay (MD -2.09 days; 95% CI, -2.82 to -1.36, P < 0.00001) compared to IVUR. Bilateral EVUR had higher risk of postoperative acute urinary retention (ARU) (8.1%) compared to bilateral IVUR (1.7%) (OR = 4.40; 95% CI, 1.33-14.58, P = 0.02). No patient undergoing unilateral EVUR or IVUR experienced ARU. Conclusion: Both EVUR and IVUR are equally effective in correcting primary VUR. Operative time and hospital stay are shorter after EVUR compared to IVUR. However, bilateral EVUR is associated with higher risk of postoperative ARU.
RESUMO
We present a rare case of Klinefelter syndrome who presented with perinatal ascites, unilateral renal agenesis and a prostatic utricle cyst. The patient was born at term via emergency Caesarean section with gross abdominal distension. Antenatally, amniocentesis revealed a fetal karyotype of Klinefelter syndrome (47, XXY), and the 34-week ultrasound scan showed a cyst measuring 17×21×27 mm located inferior-posterior to the bladder. There was no ascites noted then, but a small left pelvic kidney was present. Ultrasound kidney, ureter and bladder as well as CT scan of the thorax, abdomen and pelvis done at birth showed a solitary right kidney with large-volume ascites and no evidence of a cyst adjacent to the bladder. These findings suggest urinary ascites from an involuting left renal system or a ruptured prostatic utricle cyst. We report the first case of Klinefelter syndrome associated with a prostatic utricle cyst and unilateral renal agenesis, presenting with neonatal ascites.

INTRODUCTION: Posterior urethral valve (PUV) is the most common congenital cause of bladder outflow obstruction in male infants. Despite timely treatment, renal damage can still occur in the long-term leading to chronic kidney disease (CKD). METHODS: A retrospective review of all PUV patients in a single tertiary institution between April 1998 and July 2019 was conducted to analyze their presentations, management and outcomes. Long-term renal function, radiologic scans and somatic growth were evaluated. RESULTS: A total of 16 patients were included in this study. Two patients who defaulted all follow-ups were excluded. Seven patients (43.7%) presented in the antenatal period; four patients (25%) presented in the neonatal period and five patients (31.3%) presented in the post-neonatal period. Primary transurethral fulguration of valves was done in 13 patients, while three had vesicostomies as the primary procedure. Three patients had associated anterior urethral valves (AUV), which were treated endoscopically. Nine boys had additional procedures for diversion and undiversion, VUR, non-functioning kidney and clean intermittent catheterization. Ten patients had urodynamic studies performed, of which eight patients received anticholinergic therapy. Eleven patients had DMSA scans, of which three patients had a normal study and eight patients showed unilateral reduced function. Four patients were diagnosed with CKD on long-term follow-up duration over 5 years. All patients were shown to have good somatic growth. CONCLUSION: Patients with PUV can suffer from complications despite primary treatment. In our small cohort, a quarter of our patients developed CKD on follow-up. Thus, patients need long-term follow-up to optimize bladder and renal function.

Anorectal malformations (ARMs) are one of the more common congenital anomalies encountered in pediatric surgery where the majority are diagnosed in the early neonatal period. The etiology of ARM remains uncertain and is likely to be multifactorial. A majority of ARMs result from abnormal development of the urorectal septum in early fetal life. There can be a broad range of presentation features varying from low anomalies with perineal fistula to high anomalies mandating intricate management. To develop a standardized system for comparison in follow-up studies, the Krickenbeck classification was introduced according to the type of fistula. According to the Krickenbeck classification of ARM, those with a rectoperineal fistula are classified as low-type ARM and are usually managed with a perineal anoplasty without colostomy. In this case series, we describe two rare cases of distinct high and intermediate ARM with rectoperineal fistulas, which were thought to be low-type ARM but were subsequently found to have urethral involvement. Our cases consisted of high and intermediate ARMs, which were successfully treated with posterior sagittal anorectoplasty as described. These cases exemplified rare variants of ARM where rectoperineal fistulas can be associated with high-type anomalies. Rare-variant ARM with rectopenile or rectoscrotal fistula can be associated with high-type anomalies in contrast to classical rectoperineal fistulas. A high index of suspicion should remain in cases with previous urinary tract infection despite normal imaging. Careful planning is also needed with consideration of possible need for urethral repair during anoplasty, which was needed in both our cases.
RESUMO
PURPOSE: Pediatric solid tumors require coordinated multidisciplinary specialist care. However, expertise and resources to conduct multidisciplinary tumor boards (MDTBs) are lacking in low- and middle-income countries (LMICs). We aimed to profile the landscape of pediatric solid tumor care and practices and perceptions on MDTBs among pediatric solid tumor units (PSTUs) in Southeast Asian LMICs. METHODS: Using online surveys, availability of specialty manpower and MDTBs among PSTUs was first determined. From the subset of PSTUs with MDTBs, one pediatric surgeon and one pediatric oncologist from each center were queried using 5-point Likert scale questions adapted from published questionnaires. RESULTS: In 37 (80.4%) of 46 identified PSTUs, availability of pediatric-trained specialists was as follows: oncologists, 94.6%; surgeons, 91.9%; radiologists, 54.1%; pathologists, 40.5%; radiation oncologists, 29.7%; nuclear medicine physicians, 13.5%; and nurses, 81.1%. Availability of pediatric-trained surgeons, radiologists, and pathologists was significantly associated with the existence of MDTBs (P = .037, .005, and .022, respectively). Among 43 (89.6%) of 48 respondents from 24 PSTUs with MDTBs, 90.5% of oncologists reported > 50% oncology-dedicated workload versus 22.7% of surgeons. Views on benefits and barriers did not significantly differ between oncologists and surgeons. The majority agreed that MDTBs helped to improve accuracy of treatment recommendations and team competence. Complex cases, insufficient radiology and pathology preparation, and need for supplementary investigations were the top barriers. CONCLUSION: This first known profile of pediatric solid tumor care in Southeast Asia found that availability of pediatric-trained subspecialists was a significant prerequisite for pediatric MDTBs in this region. Most PSTUs lacked pediatric-trained pathologists and radiologists. Correspondingly, gaps in radiographic and pathologic diagnoses were the most common limitations for MDTBs. Greater emphasis on holistic multidisciplinary subspecialty development is needed to advance pediatric solid tumor care in Southeast Asia.

PURPOSE: We aim to evaluate the diagnostic value and time course response of the triple inflammatory markers: white blood cell count (WBC), neutrophil percentage (Neu), and C-reactive protein (CRP) in pediatric acute appendicitis. METHODS: A retrospective review of clinical data pertaining to 1391 patients admitted with suspicion for pediatric appendicitis from 2012 to 2017 was conducted. Triple inflammatory markers were acquired upon admission. Appendicitis was confirmed histologically post-appendectomy. The diagnostic value and time course response of these markers was trended in relation to the duration of abdominal pain on admission. RESULTS: 718 patients had histologically confirmed appendicitis. WBC and Neu demonstrate high sensitivity for early appendicitis at 94.6% and 80.0% at Day 1, while CRP demonstrates highest sensitivity of 97.9% at Day 4. The triple markers had poor overall diagnostic value when interpreted individually, however, had a high combined sensitivity of 99.7% and negative predictive value of 98.7% regardless of duration of disease. Overall negative appendectomy rate was 6.7% (n = 52). Among 19 patients with triple markers negative who underwent appendectomy, 17 (89.5%) were histologically normal. CONCLUSIONS: The triple inflammatory markers have limited diagnostic value when interpreted individually, but are strong discriminators of pediatric appendicitis when combined. Their high sensitivity and negative predictive value could potentially help patients avoid unnecessary admissions or costly imaging studies, and reduce negative appendectomy rates. In addition, their objective nature confers an advantage over existing clinical scoring systems which comprise subjective elements.

Vitellointestinal duct (VID) anomalies have been described extensively in the literature. However, an everted VID with prolapse of ileum arising from an omphalocele is rare, and its appearance at birth can be alarming and can present a diagnostic challenge. We describe a baby born to a teenage diabetic mother who was noted to have a strange exophytic mass arising from the abdominal wall. Antenatal scans had revealed multiple other malformations but not an omphalocele. He was operated on early, and the diagnosis of a patent VID with prolapse of the ileum arising from an omphalocele was only confirmed intraoperatively. The duct was resected, the ileum closed primarily and primary closure of the abdominal wall was performed without tension. He recovered well postoperatively. A brief review of similar cases is included.

OBJECTIVE: To design and examine the feasibility of a sustainable training program to build local capacity and improve obstetric outcomes in Kampong Chhnang, Cambodia. METHODS: A "train-the-trainers" model was used to conduct an obstetrics course between 2012 and 2015, its aim to reduce maternal mortality and morbidity. All Cambodian healthcare providers trained by the program were included in the study. The obstetric outcomes of all patients under the care of the trained healthcare providers were analyzed retrospectively to assess the feasibility of the program. Data from all three hospitals and 42 health centers in the province that the trainees worked at were collected from case logs. RESULTS: There was a significant increased trend in recognition of cases of postpartum hemorrhage and pre-eclampsia, and occurrence of difficult deliveries and cesarean deliveries (P<0.001). The maternal mortality ratio decreased from 64.7 per 100 000 deliveries in 2012 to 40.8 per 100 000 deliveries in 2016. CONCLUSION: This sustainable model has the potential to positively impact obstetric education and maternal outcomes and could be adopted in other resource-poor countries, particularly in Southeast Asia.

PURPOSE: The aim of our study was to develop an appendicitis score incorporating a urine biomarker, Leucine rich alpha-2-glycoprotein (LRG), for evaluation of children with abdominal pain. METHODS: From January to August 2017 we prospectively enrolled children aged 4-16â¯years old admitted for suspected appendicitis. Urine samples for LRG analysis were obtained preoperatively and quantified by enzyme-linked immunosorbent assay (ELISA) after correction for patient hydration status. The diagnosis of appendicitis was based on operative findings and histology. Logistic regression was used to identify prospective predictors. RESULTS: A total of 148 patients were recruited, of which 42(28.4%) were confirmed appendicitis. Our Appendicitis Urinary Biomarker (AuB) model incorporated urine LRG with 3 clinical predictors: 'constant pain', 'right iliac fossa tenderness', 'pain on percussion'. Area under the ROC curve for AuB was 0.82 versus 0.78 for the Pediatric Appendicitis Score (PAS) on the same cohort of patients. A model-calculated risk score of <0.15 is interpreted as low risk of appendicitis. Sensitivity for the AuB at this cutoff was 97.6%, specificity 37.7%, negative predictive value 97.6%, positive predictive value 38.3%, and negative likelihood ratio 0.06. CONCLUSION: The noninvasive AuB score appears promising as a diagnostic tool for excluding appendicitis in children without the need for blood sampling. TYPE OF STUDY: Study of diagnostic test. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Patients with anorectal malformation (ARM) and Hirschsprung's disease (HD) face long-term disturbance in bowel function even after definitive surgery. This study evaluates the quality of life (QOL) of patients with ARM and HD, and compares them to healthy controls using self-report questionnaires. METHODOLOGY: A prospective study was performed recruiting patients with ARM or HD from September 2013 to December 2014 who had primary surgery done in our institution at least 2 years prior to participation. Age-matched and gender-matched controls were enrolled from our patients with minor outpatient complaints. All participants completed the following PedsQL™ scales (maximum score 100): 4.0 Generic Core Scales, 3.0 General Well-Being (GWB) Scale and 2.0 Family Impact (FI) Module. All were also scored on bowel function (BFS), with a maximum score 20. Appropriate statistical analysis was performed, with significance level <0.05. RESULTS: There were 193 participants: 87 controls, 62 ARM, 44 HD. When comparing Core, GWB and FI scores, there were no significant differences between groups although controls had best scores indicating best QOL and general wellbeing, with least impact of the child's health on the family. BFS was significantly different with controls having best and ARM worst scores. There were no significant differences in scores between parent and child indicating intradyad consistency. There was significant positive correlation between BFS and Core (p<0.0001), and between BFS and GWB scores (p<0.005); and significant negative correlation between BFS and FI scores (p<0.0001). CONCLUSIONS: Bowel function impacts quality of life. Those with ARM and HD can achieve good quality of life comparable to controls, based on patient and caregiver self-reported outcomes. TYPE OF STUDY: Prospective comparative study LEVEL OF EVIDENCE: Level II.

INTRODUCTION: The impact of anorectal malformation (ARM) or Hirschsprung's disease (HD) in children continues into adulthood despite early surgical correction. We aimed to explore the physical, social, and emotional impacts of these conditions on youth to inform best transition care strategies. MATERIALS AND METHODS: Eligible participants were those aged between 14 and 21 years who had undergone surgery for ARM/HD in our institution. We conducted one-on-one in-depth interviews to saturation using a question guide developed from literature review and clinician expertise. Deidentified transcripts were coded by four coders (two pediatric surgeons, one psychiatrist, and one qualitative expert) for major themes using a constant comparison approach. A theoretical model for understanding the transition experience was developed using grounded theory. RESULTS: Out of 120 patients identified as eligible, 11 youth (6 males) participated in the study. Interviews lasted from 50 to 60 minutes. Four major themes emerged: (1) social support (subthemes: family as core, friends as outer support), (2) cognitive and emotional change (subthemes: realization/recognition of illness, matching emotional response), (3) impact of physical symptoms (subthemes: adverse effects of abnormal bowel habits, gaining bowel continence control leading to overall feeling of control, need to keep disease private), and (4) healthcare providers (viewed as important information sources). Themes did not differ by gender. CONCLUSION: Our model suggests that participants' understanding of bowel disease evolved over time with a "lightbulb" moment in preteens or early teens accompanied by increasing disease ownership and self-management. Clinicians should independently engage with patients in late childhood to address evolving emotional and information needs and encourage increasing autonomy. Future studies should explore communication approaches to meet transition needs of patients.

INTRODUCTION: Congenital pelviureteric junction obstruction (PUJO) is one of the most frequent causes of neonatal hydronephrosis. Obstruction at the PUJ has potential severe adverse outcomes, such as renal damage. While pyeloplasty has been established as the definitive treatment, the exact pathophysiology of congenital PUJO remains unknown. Recent research has proposed neuronal innervation defects as an etiological factor in congenital PUJO. We aim to study the expression of various neuronal markers in PUJO specimens compared with controls, and evaluate whether severity of renal disease or dysfunction pre-operatively is related to expression of neuronal markers in resected PUJO specimens. MATERIALS AND METHODS: All consecutive patients who underwent dismembered pyeloplasty at KK Women's and Children's Hospital, Singapore, for intrinsic PUJO from 2008 to 2012 were included. Patients with other co-occurring renal pathologies were excluded. Controls were obtained from nephrectomy patients with Wilm's tumor or other benign renal conditions during the same period. Specimens were stained immunohistochemically with neuronal markers protein gene product 9.5 (PGP9.5), synaptophysin, and S-100, and with CD-117, a marker for interstitial cells of Cajal (Table). Levels of expression of the markers were assessed semiquantitatively (decreased, increased or no change) in comparison with controls by two independent observers. Pre-operative data of patients' renal anatomical (ultrasonography measurements of renal pelvis size) and functional parameters (differential renal function measured using MAG-3 renal scans) were obtained. DISCUSSION: Thirty-eight PUJO specimens (38 renal units) and 20 controls were studied. Mean patient age at pyeloplasty was 25.3 months (2.9-167.6 months). Median pre-operative pelvic size was 25.0 mm (17.0-50.0 mm). Both PUJO specimens and controls showed great heterogeneity in distribution of innervation. All four immunohistochemical markers were not predictive of significant pre-operative renal pelvis dilation or pre-operative diminished renal function of the operated kidney. CONCLUSIONS: There exists marked variability in expression of neuronal markers synaptophysin, PGP9.5, and S-100, and CD-117 in PUJO specimens compared with controls. Our results show no clinical significance of the expression of neuronal markers in predicting degree of pre-operative renal pelvis dilation or differential renal function. The heterogeneity of expression of neuronal markers in PUJO specimens and controls in our population is at variance with prior studies. The etiology of PUJO is likely to be complex and multifactorial.

AIM: Our study aimed to compare the efficacy of two endoscopic techniques used for the correction of vesicoureteral reflux (VUR): subureteral transurethral injection (STING) and hydrodistension implantation technique (HIT). METHODS: A systematic review was conducted using MEDLINE, Google scholar, and Cochrane databases from 1984 to 2015. Meta-analysis of the selected studies was performed to compare the extent of reflux resolution following both techniques. RESULTS: Six observational studies met the inclusion criteria for content. These comprised 632 ureters treated by STING and 895 ureters treated by HIT procedure. All included studies utilized dextranomer/hyaluronic acid (Deflux) as the bulking agent. The overall resolution of VUR was significantly higher in HIT (82.5%) compared to STING (71.4%) [pooled odds ratio (OR)=0.54; 95% confidence interval (CI) 0.42-0.69; P<0.0001; I2=8%]. A subgroup analysis showed that HIT had better outcomes than STING for both lower grade (I-III) [OR=0.43; 95% CI 0.23-0.82; P=0.01; I2=0%] and high-grade VUR (IV-V) [OR=0.43; 95% CI 0.20-0.91; P=0.03; I2=0%]. However, there was no statistical difference in the requirement of additional injections between STING and HIT groups. CONCLUSION: HIT is superior to STING technique for resolution of VUR after Deflux injection. However, more randomized trials with longer follow-up are necessary to demonstrate the benefit of HIT compared to STING procedure. LEVEL OF EVIDENCE: Retrospective comparative studies - level III.

AIM: The aim of this study was to develop a new Children's Appendicitis Score (CAS) by combining 3 inflammatory markers and a set of predictors for suspected appendicitis in children. METHODS: 374 children aged 4-16years with suspicion of appendicitis were prospectively enrolled for the derivation cohort. Demographic characteristics, clinical features, laboratory, and histology data were collected. The outcome measure was the histological presence or absence of appendicitis. Backward logistic regression was employed to select predictors for construction of a score. Diagnostic performance of CAS was compared with the Pediatric Appendicitis Score (PAS) on a separate validation cohort. RESULTS: The combination of normal white blood cell count (WBC), neutrophil percentage, and C-reactive protein (CRP) had a 100% negative predictive value for appendicitis. We assigned 'coefficient A' as 'zero' when all triple markers were negative and 'one' when any one markers was positive. A second component of 6 predictors was identified for construction of the 'raw score': Localized right-lower-quadrant pain, generalized guarding, constant characteristic of pain, pain on percussion or coughing, WBC≥14000/L and CRP≥24g/L. CAS was generated by multiplying 'coefficient A' by 'raw score'. CONCLUSION: CAS is superior to PAS in ruling out appendicitis. Risk stratification of equivocal patients could guide the need for further diagnostic imaging examination.

AIM: Studies report that most boys with undescended testis(UDT) are referred and operated beyond the recommended age of 1 year, possibly due to lack of awareness of treatment guidelines. We investigate the level of knowledge of UDT among potential referring health-care providers. METHOD: We devised a survey on the clinical features and appropriate management of UDT. Using convenience sampling, we approached health-care professionals with regular contact with paediatric patients and final year medical students. Respondents were allowed to remain anonymous. They were categorised according to specialty and level of experience/training. RESULTS: Of 1179 approached, 203 responded. Thirty-six (24%) of 149 qualified doctors had never seen a case of UDT. Median score was 6 (range 1-9). There was no significant difference in scores when comparing specialty. Mean scores decreased significantly in trend according to level of experience. When questioned regarding timings of referral and orchidopexy, 24% of qualified doctors would not refer until 9 months of age, and 66% thought orchidopexy should be done after 1 year old. Half would stop examining for UDT after 2 years old. CONCLUSIONS: Inexperience with UDT and outdated knowledge may contribute to delays in referral for UDT. Many would stop examining for UDT at 2 years old, placing undue reliance on accurate physical examination in early childhood and indicating lack of awareness of the ascending testis. Community health initiatives must emphasise recent changes in guidelines for management of UDT.

OBJECTIVE: Undescended testis (UDT) affects 1-6% of males. Current recommendations are to correct maldescent by 1 year of age. We identify the population characteristics of children referred and managed for UDT, age at referral and orchidopexy, and patterns of referral. DESIGN, SETTING AND PATIENTS: Retrospective 5-year review of all patients operated for UDT from 2007 to 2011 in our institution. Patient demographics, neonatal diagnosis of UDT, age at referral, referral source and age at first orchidopexy were recorded. Data are reported as median (range). RESULTS: There were 513 boys with 576 undescended gonads; 450 (88%) had unilateral UDT. Congenital (present at birth) UDT was diagnosed in 287 (56%) children. Seventy-nine (15%) were premature births, 41 (8%) had associated major genitourinary abnormalities. Median age at referral was 1.1 (0-16.2) years; median age at first orchidopexy was 1.6 (0-17.2) years. When corrected for age, those with a history of prematurity and associated major genitourinary malformations were referred and operated on earlier. There was no difference in age at referral and orchidopexy when comparing unilateral versus bilateral maldescent, and palpability of UDT. Of those with congenital UDT, 70% were operated at beyond 1 year of age. Those referred from public tertiary hospitals were younger than those referred from community clinics (p<0.0001) and private healthcare institutions (p=0.003). CONCLUSIONS: Despite early diagnosis in many patients with UDT, most are referred and operated after 1 year of age, even in congenital UDT. Premature babies, those with major genitourinary anomalies, and those seen in public tertiary hospitals are referred earlier. Community health initiatives must emphasise prompt referral to allay the impact of delayed surgery.

BACKGROUND: Continuous surveillance for intussusception (IS) is important for monitoring the safety of second-generation rotavirus vaccines. The present study aimed to assess the incidence of IS in Singaporean children aged < 2 years. METHODS: This was a prospective, hospital-based, multi-center surveillance conducted in seven hospitals - two public hospitals and five private medical centers between May 2002 and June 2010 in Singapore. Diagnosis of IS (definite, probable, possible, suspected) was based on the case definition developed by the Brighton Collaboration. Children < 2 years of age who were diagnosed with IS were enrolled in this study. Incidence of IS was calculated per 100,000 child-year with its 95% confidence interval. RESULTS: Of the 178 children enrolled, 167 children with definite IS cases were considered for final analyses; 11 were excluded (six diagnosed as probable IS and four diagnosed as suspected IS; one child's parents withdrew consent). Mean age of children with definite IS was 11.6 ± 6 months; 67.7% were males. The overall incidence of IS was 28.9 (95% CI: 23.0-34.8) and 26.1 (95% CI: 22.2-30.0) per 100,000 child-year in children < 1 year and < 2 years of age, respectively. The majority of IS cases (20 [12.0%]) were reported in children aged 6 months. Most children (98.2% [164/167]) recovered, two (1.2%) children recovered with sequelae and one (0.6%) child died of septic shock. CONCLUSIONS: The incidence of IS remained low and stable in Singaporean children aged < 2 years during the study period (May 2002 to June 2010). TRIAL REGISTRATION: NCT01177839.

AIM: Transanal endorectal pull-through (TERPT) has become popular for single-stage treatment of Hirschsprung's disease. The benefits of TERPT over the conventional transabdominal approach (TAB) are still unclear. We performed a comprehensive meta-analysis comparing the clinical outcomes of TERPT and TAB. METHODS: Original articles published from 1998 to 2012 were searched from Medline, Embase, and Cochrane databases. Randomized controlled trials (RCT) and observational clinical studies (OCS) comparing TERPT and TAB were included. Outcomes evaluated included operative time, hospital stay and incidence of postoperative incontinence/soiling, constipation and enterocolitis. Pooled odds ratios (OR) were calculated for dichotomous variables; pooled mean differences (MD) were measured for continuous variables. RESULTS: Of 93 studies, 1 RCT and 11 OCS were included, comprising 444 cases of TERPT and 348 cases of TAB (215 Soave, 94 Duhamel, 24 Swenson, 15 Rehbein procedures). TERPT had shorter operative time (MD=-57.85 min; 95% confidence interval [CI], -83.11 to -32.60; P<0.00001) and hospital stay (MD=-7.06 days; 95% CI, -10.95 to -3.16; P=0.0004). TERPT had less postoperative incontinence/soiling (OR=0.58; 95% CI 0.37-0.90; P=0.01) and constipation (OR=0.49; 95% CI 0.30-0.81; P=0.005). There was no difference in incidence of postoperative enterocolitis. CONCLUSION: TERPT is superior to TAB in operative time, hospital stay, postoperative incontinence and constipation. However, more randomized controlled trials are necessary to verify the benefit of TERPT for Hirschsprung's disease.
