Is the Transrectal Diameter (TRD) Suitable for Assessing Faecal Loads and Monitoring Bowel Management in Children with Hirschsprung Disease-ReKiSo Study: Prospective Study. CHILDREN (BASEL, SWITZERLAND) 2024; 11:921. [PMID: 39201856 PMCID: PMC11353099 DOI: 10.3390/children11080921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 07/12/2024] [Accepted: 07/27/2024] [Indexed: 09/03/2024]
Abstract
BACKGROUND Constipation and outlet obstruction may persist after successful pull-through in Hirschsprung Disease (HD). The radiographic assessment of the faecal load is widely used but exposes the child to radiation. This study aims to evaluate whether the transrectal diameter (TRD) assessed with ultrasound correlates with symptoms of faecal load and whether the TRD normalises when symptoms disappear. METHOD Children with HD after pullthrough and functional constipation presenting to our colorectal clinic between 4/23 and 4/24 were assessed for symptoms of constipation, smearing and outlet obstruction, as well as healthy controls. Ultrasound measurement of the TRD was conducted. Bowel management was initiated according to our institutional pathway using Peristeen© irrigation after an orthograde disimpaction regime. RESULTS A total of 193 children underwent TRD assessment. Of 60 children with HD, 26 (43.3%) presented with obstructive symptoms, and 34 (56.7%) were asymptomatic. In asymptomatic patients with HD, the mean TRD of 2.26 cm (SD 0.61) was significantly (p < 0.001) lower than in HD with symptoms, with a mean TRD of 3.35 cm (SD 1.03). Individuals without colorectal pathology had a mean TRD of 2.04 cm (SD 0.37), and children with functional constipation and symptoms showed a mean TRD of 4.36 cm (SD 1.32). The mean TRD after symptom resolution was 2.37 cm. CONCLUSIONS Children with HD without obstructive symptoms have a TRD < 3 cm, as do controls. The transrectal diameter allows the clinician to sonographically assess the faecal load in children with HD at the bedside without radiation. The TRD is useful for monitoring a bowel management program in children with HD.

Abstract
PURPOSE To evaluate bowel management for children with colorectal pathology by measuring transverse rectal diameter (TRD) and assessing fecal load with transabdominal rectal ultrasound (TRU). METHODS Prospective case-control study of children receiving bowel management (BM) between 04/2023 and 04/2024 was done. There was inclusion of patients with Hirschsprung disease (HD), anorectal malformation (ARM) and functional constipation (FC). Patients with other congenital or neurological conditions were excluded. Control group consisted of inpatients and outpatients without abdominal complaints. FC was diagnosed according to ROM-IV-criteria. For HD and ARM, we followed a list of symptoms. To assess fecal load, we visualized the TRD using the Klijn (Klijn et al. in J Urol 172:1986-1988, 2004) method. The bladder was moderately full. The fecal load was assessed retrograde from the rectum. Follow-up was at 1/3/6 months. Secondary data were collected from medical records. Sample size calculated a priori and follow-up group with new gathered data. RESULTS p value for TRD in all groups significant with p < 0.05 and in grouped follow-up. CONCLUSION Ultrasound is a useful tool for assessing fecal load and helps diagnose constipation and monitor BM. Irrespective of colorectal pathology, a cut-off of 3 cm seems to discriminate between children without constipation/overload symptoms and asymptomatic patients. We present a radiation-free method for monitoring bowel management.

Abstract
BACKGROUND Constipation can be diagnosed clinically using the Rome criteria. Ultrasound (US), which lacks the radiation exposure of conventional X-ray, holds promise as a non-invasive tool to evaluate colonic contents and constipation. AIM To examine the role of US in the assessment of constipation. METHODS We performed a systematic search of Embase (OVID, 1984), Medline (Ovid, 1946), Cochrane Central, ClinicalTrials.gov and Australia New Zealand Clinical Trials Registry from database inception to 26 January 2024 according to PRISMA guidelines and prospectively registered with PROSPERO. All studies using US to assess constipation or colonic contents in either adults or children were included. Rectal diameter measurements were pooled in meta-analysis. Risk of bias was assessed using the Newcastle Ottawa Scales and Joanna Briggs Institute checklists. RESULTS Of 12,232 studies screened, 51 articles (6084 patients; 3422 children) describing US to assess symptoms in patients with constipation were included. Most studies used Rome criteria to diagnose constipation. Rectal diameter was associated with clinical constipation in 29 paediatric studies (3331 patients). Meta-analysis showed the mean rectal diameter of constipated patients was significantly higher than controls (mean difference 12 mm, 95% confidence intervals (CI): 6.48, 17.93, p < 0.0001, n = 16 studies). Other features of constipation on US included posterior acoustic shadowing and echogenicity of luminal contents. CONCLUSION US is an appealing imaging modality to assess luminal contents and constipation. Further well-designed studies are required to validate US metrics that accurately identify constipation.

J Pediatr Urol 2024; 20:223.e1-223.e6. [PMID: 37968162 DOI: 10.1016/j.jpurol.2023.11.001] [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: 05/27/2023] [Revised: 09/30/2023] [Accepted: 11/02/2023] [Indexed: 11/17/2023]
Abstract
INTRODUCTION Kidney ureter bladder radiography (KUB) is widely used for the evaluation of constipation in children with bladder and bowel dysfunction (BBD); however, there is varying evidence to support its routine diagnostic use. One drawback to KUB is radiation exposure. The dangers of radiation in children are well-documented, and per As Low As Reasonably Achievable, non-beneficial radiation should be avoided. This risk is especially high in children who undergo repeated imaging in the follow up of constipation treatment. OBJECTIVE We sought to assess the utility of KUB in diagnosing children with BBD by comparing it to four diagnostic tests and/or validated instruments: the Dysfunctional Voiding Symptom Score (DVSS), Rome IV criteria, rectal diameter on ultrasound (RD), and the Bristol Stool Form Score (BSFS). STUDY DESIGN We prospectively enrolled a cohort of patients presenting to an academic pediatric urology practice with symptoms of BBD. Severity of stool burden on KUB (mild, moderate, or severe), RD on ultrasound (≥3.4 cm), DVSS, Rome IV, and BSFS were obtained for each patient. All imaging was interpreted by a pediatric radiologist and pediatric urologist. Primary outcomes were the association between the four diagnostic tests and KUB stool burden. Bivariate analysis of all individual variables versus KUB was performed, as well as multivariate regressions to determine if multiple measures were predictive of KUB stool burden when combined. RESULTS Between October 2020 and May 2022, 50 patients were enrolled. All children were under the age of 18, with a median age of 8 years (IQR 3-13). 38 % were male. Median BMI-for-age-percentile was 80.8 (IQR 50.3-98.3). When comparing individual variables to KUB in bivariate analyses, it was found that RD on ultrasound is predictive of significant stool burden on KUB (p = 0.03). No other individual variables were predictive. In the multivariate analyses, no combination of tests was found to be predictive of KUB. DISCUSSION We compared the effectiveness of four commonly used diagnostic tests in children with BBD to validate the use of KUB. In conclusion, our results support the use of RD on ultrasound as a non-radiating alternative to KUB to assess stool burden. Data also suggest that KUB for fecal load does not correlate with urinary (DVSS) or bowel (Rome IV, BSFS) symptoms in BBD, and that symptoms scores should still be used independently for diagnosis and monitoring of treatment response. CONCLUSION In conclusion, KUB has a limited role in the diagnosis of BBD.

Abstract
OBJECTIVE To test whether sonographically determined fecal width (SDFW) correlates with symptom improvement in a population of children with bladder and bowel dysfunction (BBD) managed with standard urotherapy (SU), even for those patients lacking initial bowel complaints. METHODS We retrospectively analyzed 200 pediatric BBD patients managed with SU for at least 3 months. Self-reported symptom improvement (complete, partial, no response) following International Children's Continence Society guidelines was tabulated. Patients with complex urologic diagnoses other than vesicoureteral reflux (VUR) were excluded. Pharmacotherapy choice, physical therapy (PT), urinary tract infection (UTI) occurrence, and VUR status were tabulated. SDFW was recorded. Non-parametric analysis of variants (ANOVA) and parametric/non-parametric t testing were used for analysis. RESULTS Patients had a mean age of 9.5 years (4-12). Forty-eight patients had no gastrointestinal complaints at presentation. Urotherapy yielded complete, partial, and no responses in 14% (n = 27), 33% (n = 67), and 53% (n = 106) of patients, respectively. The average SDFW for those patients with complete response (2.6 cm) was smaller than the SDFW of those with a partial response (3.1 cm) or no response (3.3 cm) (P = .0001). Non-compliance led to greater SDFW compared to compliant patients (3.7 cm and 3.1 cm, respectively, P = .0001). Fecal width was unaffected by VUR, UTI, PT, or pharmacotherapy. CONCLUSION SDFW correlates well with symptom improvement in pediatric patients managed for BBD, confirming our hypothesis. SDFW is reasonable as single objective parameter to identify successful management in patients with BBD, extending to those without bowel complaints at presentation.

Abstract
INTRODUCTION Disorders of Gut-Brain Interactions (DGBI) are a common clinical problem in children and pose significant challenges to the attending pediatrician. Radiological investigations are commonly ordered to evaluate these children. AREA COVERED This review focuses on the current best practice of using radiological investigations in DGBIs and how novel radiological investigations could revolutionize the assessment and therapeutic approach of DGBI in children. EXPERT OPINION We believe imaging in DGBI is still in its early stages, but it has the potential to revolutionize how we diagnose and treat children with DGBI. As the understanding of the gut-brain axis continues to grow, we can expect to see the disappearance of conventional imaging techniques and the emergence of more sophisticated imaging techniques with less radiation exposure in the future which provide more clinically meaningful information regarding the gut-brain axis and its influence on intestinal function. Some of the novel imaging modalities will be able to broaden our horizon of understanding DGBI in children providing more useful therapeutic options to minimize their suffering.

Abstract
PURPOSE Parasacral Transcutaneous Electrical Stimulation (TENS) is one of the treatments for children with Bladder and Bowel Dysfunction (BBD). Some studies showed that children with increased Rectal Diameter (RD) have more Functional Constipation (FC). However, RD prediction in maintenance of BBD after treatment was never evaluated. Our aim is to evaluate the association between RD and response to treatment in children and adolescents with BBD. MATERIALS AND METHODS This study evaluated patients from 5-17 years old with BBD. Dysfunctional Voiding Scoring System (DVSS), Rome IV criteria, and the Constipation Score were used. RD was measured using abdominal ultrasound before treatment according to the technique established by Klijn et al. and was considered enlarged when >3cm. No laxatives were used during treatment. Descriptive analysis and binary regression were performed and the area under the ROC curve was calculated. RESULTS Forty children were included (mean age 8.4±2.8 years, 52.5% male). Before treatment, RD was enlarged in 15 children (37.5%) (mean diameter 3.84±0.6cm), with FC persisting post-treatment in 11/15(73.3%). Those patients also required more laxatives following treatment and had more severe FC. Binary regression showed pretreatment RD to be an independent predictor of the persistence of FC post-treatment (OR=9.56; 95%CI:2.05-44.60). In ROC curve analysis, the sensitivity was 100% (95%CI: 0.49-1.0) and specificity 77.14% (95%CI:0.60-0.90) for rectal diameter >3 cm. The likelihood ratio was 4.38 (95%CI:2.40-8.0) for the persistence of BBD following treatment. CONCLUSION RD appears to be relevant in the evaluation of children with BBD, not only as a diagnostic tool but also as a predictor of treatment outcome.

Abstract
AIM Transabdominal rectal ultrasound (TRU) is used to measure transverse rectal diameter (TRD) in order to diagnose functional constipation (FC) and megarectum, and to evaluate treatment. The proposed cut-off value is 3.0 cm. Currently, no standardised values exist for children below the age of 4. We used repeated TRUs to establish reference TRD values in healthy infants and to describe rectal diameter in infants with FC. METHODS This prospective observational cohort study enrolled healthy term babies from a maternity department. TRD measurements were taken at 2 and 12 months of age, and questionnaires completed in interviews helped diagnose FC according to Rome III criteria. RESULTS Two hundred TRUs were performed on 110 infants (62 males). In infants without FC anytime, the mean TRD at 2 months was 1.56 (SD 0.32) cm and at 12 months 1.78 (0.47) cm, while the 95th percentiles were 2.26 and 2.64 cm, respectively. In 77 infants with two TRUs, the mean increase was 0.21 cm (95% confidence interval: 0.099-0.318). Thirteen infants were diagnosed with FC during the study period. At 2 and 12 months of age, there was no difference in TRD between infants with and without FC. CONCLUSION TRD increased from 2 to 12 months. We suggest 2.3 cm as an upper limit for normal TRD at 2 months and 2.6 cm at 12 months. Infants diagnosed with FC did not have a greater TRD than infants without, either before or after treatment. Further studies are needed to evaluate the usefulness of TRU in infants with FC or megarectum.

Abstract
Mesalazine (MSZ) suppositories are a first-line medication for the localized treatment of ulcerative colitis (UC). However, the frequent defecation of patients with UC influences the retention of the suppository in the rectum and multiple doses have to be applied. Here, a mesalazine hollow suppository (MHS) is developed using three-dimensional (3D) printing. The MHS is composed of an inner supporting spring and an outer MSZ-loaded curved hollow shell. Springs were prepared using fused deposition modeling (FDM) 3D printing with thermoplastic urethane filaments, followed by splitting. The optimal parameters, including elasticity, filament diameter, spring inner diameter, and filament distance, were screened. The shell was prepared by FDM 3D printing utilizing MSZ, polyvinyl alcohol, and polyethylene glycol, which were assembled with springs to obtain FDM 3D-printed MHS (F-MHS); if 3D-printed metal molding was used in preparing shell, mold-formed MHS (M-MHS) was obtained. The F-MHS exhibited faster MSZ release than the M-MHS; therefore, the molding method is preferable. The inserted M-MHS was retained in the rat rectum for 5 h without affecting defecation. M-MHS alleviated tissue damage of UC rats and reduced inflammation with low levels of myeloperoxidase and proinflammatory cytokines. Personalized MHS is a promising medication for the localized treatment of UC.

Abstract
AIM The study aimed primarily to compare the transverse rectal diameter in children with functional constipation (FC) and children without constipation in different age groups, and between cases of constipation at baseline and after treatment. Secondary aim was to determine factors that could affect the transverse rectal diameter. METHODS A controlled prospective study, including a total of 100 children between the ages of 2 and 11 years, who were divided into 50 patients suffering from constipation according to Rome IV criteria and 50 age- and sex-matched controls. Transverse rectal diameter was measured at presentation, and after 3 months of laxative therapy and behavioural modification. RESULTS Initial rectal diameter was significantly different between cases (3.55 cm (interquartile range, IQR), 3.2-4) and controls (2.3 cm (IQR, 1.8-2.5)), P value < 0.001, and it was also significantly different between those above and below 4 years, so a separate cut-off point for diagnosis of constipation was suggested being >3 cm for the former and >2.5 cm for the latter. After 3 months of follow-up, rectal diameter significantly reduced to become 2.6 (IQR, 2-2.8), P value < 0.001. Duration of symptoms positively correlated with rectal diameter. CONCLUSIONS Ultrasound measurement of rectal diameter is an important tool to diagnose and follow-up functional constipation in children. Different values of rectal diameter are found between those above and below 4 years of age.

Abstract
AIM Constipation is one of the most common complaints in childhood affecting the quality of life of both children and parents. This study intends to investigate rectal measurements on ultrasound and their relationship with bowel habits. METHODS In this cross-sectional study, 100 children with functional constipation (FC) referred to a single hospital between 2018 and 2019 were enrolled. After obtaining informed consent, a questionnaire including demographic and constipation characteristics was completed, and a physical examination including digital rectal examination (DRE) was performed. Complete abdominopelvic ultrasound was then performed. Target measurements included rectal transverse diameter (RTD), rectal anterior wall thickness (RAWT) and the presence of faecal impaction. RESULTS One hundred children with a mean age of 7.68 ± 3.30 years were present in the study. The mean duration of constipation was 15.86 ± 13.34 months. In 14% of children, painful defaecation was reported. 88% of children had some degree of faecal incontinence. According to the ultrasound findings, the mean RTD and RAWT were 3.39 ± 0.73 cm and 2.77 ± 0.68 mm, respectively, and faecal impaction was present in 70% of cases. There was a positive correlation between RTD and RAWT with age, duration of constipation and the presence of hard stools, and there was a negative correlation with frequency of defecation (P < 0.05). CONCLUSION RTD and RAWT increased with increasing constipation duration and the presence of hard stools and decreased with increasing frequency of defaecation. DRE could be omitted from the initial clinical assessment if you had access to reliable ultrasound data.

Abstract
INTRODUCTION To examine the reduction of transverse rectal diameter and its effect on bladder dynamics in children with spinal dysraphism. METHODS We prospectively evaluated 61 consecutive children with spinal dysraphism, 25 (41%) boys and 36 (59%) girls, aged 4 to 16 years; mean age 9.3 ± 3.8 years, who received bowel management. All children underwent echosonographic measurement of transverse rectal diameter before and after starting bowel management. Also, all the patients had undergone urodynamic studies before and after starting bowel management, with no changes in their urological treatment. RESULTS Bowel management caused an decrease in transverse rectal diameter by 56 ± 7.2% (p < 0.001). In addition, a decrease was observed for maximal detrusor pressure by 27.8 ± 7.8% (p < 0.001), leak point pressure by 37.2 ± 4.4% (p < 0.001), and PVR by 36.7 ± 8.0 (p < 0.001). Maximum bladder capacity was significantly increased after bowel management in both non-adjusted (36.4 ± 14.8%; p < 0.001) and adjusted analysis for age (39.4 ± 14.3%, p < 0.001). Detrusor compliance was also increased by 89.2 ± 24.8% (p < 0.001). Female gender and % change of maximal detrusor pressure were significant predictors of transversal rectal diameter change in univariate as well as in multivariate analysis (OR = 10.548, 95% CI 2.309-48.180; p = 0.002 and OR = 1.121, 95% CI 1.009-1.245; p = 0.034). CONCLUSIONS Decrease in transverse rectal diameter may be useful for bladder function and urodynamic findings in children with spinal dysraphism. Therefore, decrease in transverse rectal diameter should be a supplement to standard urotherapy.

Abstract
BACKGROUND The aim of this study was to examine the correlation between the transverse rectal diameter and urodynamic findings in children with neurogenic bowel and bladder dysfunction. METHODS Between 2014 and 2022, we prospectively evaluated 81 consecutive spina bifida children with neurogenic bowel and bladder dysfunction (35 boys and 46 girls, mean age 9.5 ± 3.4 years). All patients underwent echosonographic measurement of transverse rectal diameter and urodynamic studies. RESULTS We found a strong negative correlation between transverse rectal diameter and maximum bladder capacity (r = -0.682, p < 0.001) and compliance (r = -0.690, p < 0.001). There was also a strong positive correlation between transverse rectal diameter and maximal detrusor pressure (r = 0.650, p < 0.001), leak point pressure (r = 0.793, p < 0.001), and PVR (r = 0.762, p < 0.001). In ROC analysis, transverse rectal diameter demonstrated good performance for distinguishing children with upper urinary tract deterioration, with an AUC of 0.857 (95% CI 0.761-0.953). A transverse rectal diameter ≥40 mm was 83.3% sensitive and 100% specific for the diagnosis of unfavorable urodynamic patterns. CONCLUSION There is a correlation between the transverse rectal diameter and urodynamic findings in children with neurogenic bowel and bladder dysfunction. Ultrasonographically assessed transverse rectal diameter of ≥40 mm may be used as a risk factor for upper urinary tract deterioration (unfavorable urodynamic findings). We suggest the transverse rectal diameter echosonographic measurement use as an integral part of the diagnostic approach in children with neurogenic bowel and bladder dysfunction, as it can help decision-making while waiting for urodynamic testing.

Abstract
AIM This study aimed to compare the transverse diameter and thickness of the anterior wall of the rectum in children with normal bowel movement and children with functional constipation in different age groups. Another objective was to find correlations of rectum sizes with faecal incontinence and constipation duration. METHODS In the study, we included children with normal bowel movement and functional constipation diagnosed based on the Rome III and Rome IV criteria. We collected clinical data from the parents. We measured the rectum transverse diameter and the thickness of the anterior wall by abdominal ultrasound. RESULTS The study included 65 children, 31 with normal bowel movement and 34 with functional constipation. The rectum transverse diameter and the thickness of the anterior wall had statistically significant higher values in patients with constipation (P < 0.05). There was a moderate and significant correlation between the duration of the disease (mean ± standard deviation = 31.7 ± 33.1 months) and rectum transverse diameter (r = 0.54; P = 0.0009). The rectum transverse diameter correlated moderately with the presence of faecal incontinence (r = 0.62; P = 0.003), but the thickness of the anterior wall did not correlate with this symptom (r = 0.02; P = 0.39). CONCLUSIONS We found statistically significant differences between the transverse rectal diameter and thickness of the rectum anterior wall, measured by abdominal ultrasound, in children with functional constipation compared with normal defaecation patterns. Faecal incontinence and long-term constipation were correlated with the increased rectum diameter.

Abstract
BACKGROUND Abdominal ultrasound and anorectal manometry are part of the investigations used to assess children with functional constipation. This study aimed at assessing the changes in the characteristics of the rectoanal inhibitory reflex (RAIR) in children with functional constipation and correlating them with the dimensions of the rectum, measured by abdominal ultrasound. A secondary objective was to compare the rectum size in children with and without constipation. METHOD We retrospectively reviewed the clinical data and investigations results of 51 children (mean age±standard deviation (SD) = 5.8±3.5 years) with functional constipation who came to our clinic between January 2013 and February 2020. The assessment of these patients included both the assessment of the transverse diameter of the rectal ampulla by abdominal ultrasound and anorectal manometry. The studied parameters of RAIR were: the minimal volume of air necessary to induce RAIR, in all the patients with functional constipation, and in 20 of them, relaxation time, latency and relaxation percentage. A control group was formed of 27 children (mean age±SD = 5.1±4 years) without digestive diseases and with normal intestinal transit, who were assessed by abdominal ultrasound. RESULTS The mean value ±SD of the volume of air necessary to induce RAIR was 21.9±12.1 cm3 air. There was no correlation between the rectum transverse diameter and the minimal air volume that triggered RAIR (r=-0.01, p=0.94). The mean value ±SD of the transverse diameter of the rectum in patients with functional constipation was 39±14 mm, and in children without constipation 26±6 mm (p<0.05). The mean duration of the symptoms in children with functional constipation was 2.8 years. CONCLUSIONS There were no correlations between the volume of air that induced the RAIR and the transverse diameter of the rectum in children with functional constipation. The transverse diameter of the rectum was increased in children with long-term functional constipation.

Role of transverse diameter of the rectum in lower urinary tract symptoms and functional constipation in children and adolescents. J Paediatr Child Health 2021; 57:121-125.

Abstract
AIM Although a correlation has been reported between enlarged rectal diameter and functional constipation (FC), the relevance of measuring the transverse diameter of the rectum for diagnosing FC remains unclear, even in patients with lower urinary tract symptoms (LUTS). This study aimed to measure rectal diameter in children/adolescents diagnosed with LUTS, with and without FC. METHODS This cross-sectional study included 4-17 years old children/adolescents attending a multidisciplinary outpatient clinic for urinary disorders between June 2016 and November 2018. All participants had LUTS, with or without FC. Those incorrectly completing the study questionnaires or with neurological and/or anatomical abnormalities of the genitourinary and/or gastrointestinal tract were excluded. Urinary symptoms were evaluated using the dysfunctional voiding symptom score and FC was assessed using the Rome IV criteria. Transabdominal ultrasonography was used to evaluate the bladder and measure rectal diameter. A transverse diameter ≥3 cm defined an enlarged rectum. Bladder capacity (i.e. the bladder volume immediately before voiding), post-void residual urine, bladder wall thickness and first volume voided after ultrasonography were measured. RESULTS Mean age was 8.9 ± 3.2 years and 55.1% were female. Of 107 patients included, constipation was diagnosed in 72 (67.3%), and lower urinary tract dysfunction in 90 (84.1%). In 72 participants (67.3%), lower urinary tract dysfunction was associated with FC, constituting bladder and bowel dysfunction. Rectal diameter was increased in 51 patients (47.7%). There was no association between rectal diameter ≥ 3 cm and urinary urgency, enuresis, increased daytime urinary frequency, nocturia, daytime incontinence, constipation, severe LUTS or bladder and bowel dysfunction (P > 0.05 in all cases). However, increased rectal diameter was associated with at least one episode of faecal incontinence per week in constipated patients (P = 0.02). There was no correlation between rectal diameter and dysfunctional voiding symptom score (rs = 0.00), bladder capacity (rs = 0.01), post-void residual urine (rs = 0.05), bladder wall thickness (rs = 0.00) or first volume voided after ultrasonography (rs = 0.06); P > 0.05 in all cases. CONCLUSION There was no association between the current cut-off point characterising the rectum as distended and the severity of urinary symptoms, even when FC was present. However, the complaint of faecal incontinence associated with increased rectal diameter may suggest functional constipation. The cross-sectional design, however, constitutes a limitation. Further studies may be able to determine the ideal diagnostic cut-off point for bowel and urinary dysfunction. Rectal diameter was not associated with the intensity of LUTS, with or without FC. However, the complaint of faecal incontinence associated with increased rectal diameter may suggest functional constipation.

Abstract
The aim of this study was to assess rectal feces storage condition by a pocket-size ultrasonography (PUS) in healthy adults so as to define normal rectal defecation desire. Participants were first assessed rectum by PUS imaging immediately after defecation desire (pre-defecation). Nurses checked the amount and quality of the participants' feces using King's Stool Chart and Bristol stool scale. Finally, PUS was performed for defecation with no defecation desire (post-defecation). Pre-defecation PUS detected high echo area in all patients. All of the post-defecation PUS did not detect high echo area (perfectly no recognizable high echo area in 54.5%, high echo line in 36.4%, and low echo of entire circumference in 9.1% of the patients). Average diameter of rectal crescent was 4.22 ± 0.8 cm. Bristol Stool Scale 1 or 2 (indicating hard stool) of pre-defecation PUS indicated high echo area and acoustic shadow in 100% of the patients. This study showed that healthy adult with defecation desire had high average rectal echo area of 4.0 cm in diameter. PUS may be able to define the rectum diameter for defecation desire of elderly people. PUS is capable of assessing fecal retention of the rectum for point-of-care examinations in home care.

Abstract
ABSTRACT BACKGROUND: Ultrasonography has shown to be useful in the diagnosis of constipation. OBJECTIVE: The aim of this study was to compare the rectal diameter and rectal wall thickness in children with and without constipation. METHODS: Children with the diagnosis of constipation according to Rome III criteria were included in the study. The children underwent transabdominal sonography for the evaluation of rectal diameter and rectal wall thickness. Ultrasonography was performed with a full bladder. Children without constipation who underwent abdominal sonography were assigned to the control group. RESULTS: The rectal diameter was larger in children with constipation than in children without constipation (31.72±9.63 mm vs 19.85±4.37 mm; P=0.001). The rectal wall was thinner in children with constipation than in children without constipation (1.75±0.33 mm vs 1.90±0.22 mm; P=0.032). There was no significant difference between boys and girls with constipation in terms of rectal diameter (31.02±8.57 mm 32.77±11.35 mm; P=0.63). CONCLUSION: Transabdominal rectal diameter measurement may be useful in the diagnosis of constipation.

Abstract
AIMS To evaluate the role of soft tissue and ligaments damage and level of pelvic muscles activation versus intra-abdominal pressure, on pelvic organ prolapse. METHODS This was a computational modeling based on the finite element analysis. Three pelvic muscles, four pelvic ligaments, and three organs (urethra, vagina, and rectum) were simulated. The model was subjected to total 41 472 analysis cases including three intra-abdominal pressures, two damaging levels for the ligaments, three damaging levels for the muscles, and four intentional levels of activation for muscles. RESULTS Increased intra-abdominal pressures caused significant statistical increase of the pelvic organ prolapse (P = 0.000) up to 10 mm downward. Ligaments' defect had no statistically-significant effect on prolapse of the organs (P = 0.981 for rectum, P = 0.423 for urethra, and P = 0.752 for vagina). Damage in the pelvic floor muscles and low intentional level of activation also deteriorated the prolapse (P = 0.000). CONCLUSION Increase of the intra-abdominal pressure (IAP) as may be existed during pregnancy or physical activity increased the organ prolapse. Damages of the ligaments caused less effects on the prolapse. Loss of the passive properties of the muscles which is probable after delivery or aging moderately deteriorated the prolapse disorder. However, activation of the pelvic floor muscles prevented the prolapse. Different recruitments of the muscles, specifically the pubococcygeus (PCM), could compensate the possible defects in other tissues. Targeted pelvic floor muscle training (PFMT) could also be effective in older adults due to considerable role of the pelvic muscles' intentional activation.

Abstract
PURPOSE OF REVIEW The symptoms of lower urinary tract dysfunction (LUTD) including urinary incontinence, frequency, and urgency are among the most common reasons children are referred to pediatric urologists. Despite this, the workup for LUTD is often time consuming and a source of frustration for patients, parents, and clinicians alike. In the current review, we summarize the important role non-invasive testing plays in the diagnosis and management of children with LUTD and to show how use of these tests can help avoid the need for more invasive testing in the majority of children. RECENT FINDINGS Non-invasive tests such urine studies, uroflowmetry ± simultaneous electromyography, assessment of post-void residual, renal/bladder ultrasound, and pelvic ultrasound when used appropriately can provide valuable information to facilitate decision making during the evaluation of children with LUTD. While these tests should be employed prior to more invasive testing such as urodynamic studies, they can often act as a surrogate for the more invasive tests. Non-invasive tests can help us in our goal of improving diagnostic ability to better classify the child's LUTD into an actual condition which allows targeted treatment in the hope of better outcomes and more satisfied patients and families.

Measuring the Transrectal Diameter on Point-of-Care Ultrasound to Diagnose Constipation in Children. Pediatr Emerg Care 2018; 34:154-159.

Abstract
OBJECTIVES The aim of the study was to determine the test performance characteristics for point-of-care ultrasound in diagnosing constipation, through measuring the transrectal diameter (TRD). We sought to develop a sonographic numeric cutoff value for diagnosing constipation. Secondary objectives included whether certain patient characteristics would affect the TRD measurement and the accuracy of the TRD in comparison with abdominal radiographs. METHODS We conducted a prospective, cohort study of pediatric patients between the age of 4 and 17 years, presenting with abdominal pain to a pediatric emergency department. A point-of-care ultrasound was performed with a phased array transducer (5-1 MHz). In addition to a thorough history and physical examination, each patient was administered with the Rome III questionnaire, which served as the criterion standard for the diagnosis of constipation. Radiographs and enema treatments were performed at the discretion of the treating attending physician. When enemas were administered, a postenema TRD measurement was obtained. RESULTS Fifty subjects were "constipated" or "nonconstipated," as determined by the Rome III questionnaire. A TRD cutoff of 3.8 cm or greater correlated with the diagnoses of constipation (P < 0.001). Ultrasound-diagnosed constipation had a sensitivity of 86% (95% confidence interval, 69%-96%), specificity of 71% (95% CI, 53%-85%), negative predictive value of 0.87 (95% CI, 0.68-0.95), and positive predictive value of 0.70 (95% CI, 0.52-0.84). The TRD measurement was not affected by patient physical characteristics or bladder fullness. In 7 patients, an enema was administered. There was an overall mean (SD) decrease of 1.22 (1.62) cm; this difference was not statistically significant (P = 0.093). Abdominal radiographs were performed in 25 patients. When compared with abdominal radiographs, ultrasound had a higher specificity of 71% (95% CI, 53%-85%), but this difference was not statistically significant. Ultrasound performed similarly to abdominal radiographs with regard to sensitivity 86% (95% CI, 67%-95%), positive predictive value of 0.70 (95% CI, 0.52-0.84), and negative predictive value of 0.87 (0.68-0.95). In 22 of 25 patients who received radiographs, the ultrasound diagnosis was the same as the radiologist read of the radiographs. Potentially, 88% of radiographs could have been avoided in these patients. CONCLUSIONS In pediatric patients with abdominal pain, there is a strong correlation of an enlarged TRD with constipation. Our results suggest that point-of-care ultrasound is a useful adjunct for diagnosing constipation and has the potential to replace the use of abdominal radiographs.

Abstract
BACKGROUND To assess the usefulness of rectal diameter measurement on ultrasonography as a diagnostic tool for fecal retention in children. METHODS One hundred children (median age, 5.0 years), consisting of 80 with functional constipation and 20 without constipation, participated in the study. All patients underwent physical examination that included digital rectal examination. Forty-five children underwent ultrasonography in three differential planes: transection above the symphysis; under the ischial spine; and at the bladder neck. The measurement of the rectal diameter at the transection above the symphysis could most easily detect fecal retention and had the closest correlations with retention among the three planes. RESULTS Rectal diameter was wider at all measuring points (35.2 vs 20.9 mm above the symphysis, P < 0.0001; 35.7 vs 24.0 mm under the ischial spine, P < 0.0001; and 19.4 vs 8.7 mm at the bladder neck, P < 0.0001) in children with fecal retention than in those with no fecal retention. With regard to presence of constipation, children with fecal retention had a wider rectal diameter above the symphysis than those with no fecal retention (children with functional constipation, 35.3 vs 20.0 mm, P < 0.0001; children without constipation: 32.6 vs 14.6 mm, P = 0.0026). The cut-off for the rectal diameter measured above the symphysis to identify fecal retention was 27 mm, with high sensitivity and specificity (95.5% and 94.1%, respectively). CONCLUSION Ultrasound rectal diameter measurement can be used to detect fecal retention in children.

Abstract
Bladder and bowel dysfunction (BBD) describes a spectrum of lower urinary symptoms (LUTS) accompanied by fecal elimination issues that manifest primarily by constipation and/or encopresis. This increasingly common entity is a potential cause of significant physical and psychosocial burden for children and families. BBD is commonly associated with vesicoureteral reflux (VUR) and recurrent urinary tract infections (UTIs), which at its extreme may lead to renal scarring and kidney failure. Additionally, BBD is frequently seen in children diagnosed with behavioural and neuropsychiatric disorders such as attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Patients with concomitant BBD and neuropsychiatric disorders have less favourable treatment outcomes. Early diagnosis and treatment of BBD are critical to avoid secondary comorbidities that can adversely impact children's kidney and bladder function, and psychosocial well-being. The majority of patients will improve with urotherapy, adequate fluid intake, and constipation treatment. Pharmacological treatment must only be considered if no improvement occurs after intensive adherence to at least six months of urotherapy ± biofeedback and constipation treatment. Anticholinergics remain the mainstay of medical treatment. Selective alpha-blockers appear to be effective for improving bladder emptying in children with non-neurogenic detrusor overactivity (DO), incontinence, recurrent UTIs, and increased post-void residual (PVR) urine volumes. Alpha-1 blockers can also be used in combination with anticholinergics when overactive bladder (OAB) coexists with functional bladder outlet obstruction. Minimally invasive treatment with onabotulinumtoxinA bladder injections, and recently neurostimulation, are promising alternatives for the management of BBD refractory to behavioural and pharmacological treatment. In this review, we discuss clinical presentation, diagnostic approach, and indications for behavioural, pharmacological, and surgical treatment of BBD in children based on a thorough literature review. Expert opinion will be used when scientific evidence is unavailable.

Abstract
Rectal enemas that contain prophylactic levels of anti-HIV microbicides such as tenofovir have emerged as a promising dosage form to prevent sexually transmitted HIV infections. The enema vehicle is promising due to its likely ability to deliver a large amount of drug along the length of the rectal canal. Computational models of microbicide drug delivery by enemas can help their design process by determining key factors governing drug transport and, more specifically, the time history and degree of protection. They can also inform interpretations of experimental pharmacokinetic measures such as drug concentrations in biopsies. The present work begins rectal microbicide PK modeling, for enema vehicles. Results here show that a paramount factor in drug transport is the time of enema retention; direct connectivity between enema fluid and the fluid within rectal crypts is also important. Computations of the percentage of stromal volume protected by a single enema dose indicate that even with only a minute of enema retention, protection of 100% can be achieved after around 14 minutes post dose. Concentrations in biopsies are dependent on biopsy thickness; and control and/or knowledge of thickness could improve accuracy and decrease variability in biopsy measurements. Results here provide evidence that enemas are a promising dosage form for rectal microbicide delivery, and offer insights into their rational design.

Abstract
Objective To assess the correlation between the anorectal function and bladder detrusor function in patients with complete spinal cord injury (SCI) according to the type of lesion. Methods Medical records of twenty-eight patients with SCI were included in this study. We compared the anorectal manometric and urodynamic (UD) parameters in total subjects. We analyzed the anorectal manometric and UD parameters between the two groups: upper motor neuron (UMN) lesion and lower motor neuron (LMN) lesion. In addition, we reclassified the total subjects into two groups according to the bladder detrusor function: overactive and non-overactive. Results In the group with LMN lesion, the mean value of maximal anal squeeze pressure (MSP) was slightly higher than that in the group with UMN lesion, and the ratio of MSP to maximal anal resting pressure (MRP) was statistically significant different between the two groups. In addition, although the mean value of MSP was slightly higher in the group with non-overactive detrusor function, there was no statistical correlation of anorectal manometric parameters between the groups with overactive and non-overactive detrusor function. Conclusion The MSP and the ratio of MSP to MRP were higher in the group with LMN lesion. In this study, we could not identify the correlation between bladder and bowel function in total subjects. We conclude that the results of UD study alone cannot predict the outcome of anorectal manometry in patients with SCI. Therefore, it is recommended to perform assessment of anorectal function with anorectal manometry in patients with SCI.

Abstract
BACKGROUND Fecal incontinence (FI) in children is frequently encountered in pediatric practice, and often occurs in combination with urinary incontinence. In most cases, FI is constipation-associated, but in 20% of children presenting with FI, no constipation or other underlying cause can be found - these children suffer from functional nonretentive fecal incontinence (FNRFI). OBJECTIVE To summarize the evidence-based recommendations of the International Children's Continence Society for the evaluation and management of children with FNRFI. RECOMMENDATIONS Functional nonretentive fecal incontinence is a clinical diagnosis based on medical history and physical examination. Except for determining colonic transit time, additional investigations are seldom indicated in the workup of FNRFI. Treatment should consist of education, a nonaccusatory approach, and a toileting program encompassing a daily bowel diary and a reward system. Special attention should be paid to psychosocial or behavioral problems, since these frequently occur in affected children. Functional nonretentive fecal incontinence is often difficult to treat, requiring prolonged therapies with incremental improvement on treatment and frequent relapses.

Abstract
AIM To study whether diurnal variations and time in relation to defecation has to be taken into account when measurements of rectal diameter are used to determine faecal impaction in constipated children. METHODS Repeated ultrasound measures of rectal diameter were performed in 28 children (14 constipated/14 healthy, aged between 4 and 12 years) every third hour during 24 h. After defecation, three additional scans were performed at 1-h intervals. RESULTS No diurnal variation in rectal diameter was found in the healthy group. In the constipated group, mean rectal diameter was significantly larger at 2 pm (P = 0.038) and 5 pm (P = 0.006). There were significant differences between rectal diameter in the healthy group and the constipated group at 2 pm (P = 0.016) and 5 pm (P = 0.027). When we omitted the rectal diameter of five constipated children who had their first bowel movement after 5 pm, there were no difference between groups (2 pm (P = 0.103)/5 pm (P = 0.644) ). Only in the constipated group, rectal diameter exceeded 3 cm without the patients feeling the urge to defecate. CONCLUSION We found no independent daily variation in either group without relation to defecation. There was a relation between defecation and changes in rectal diameter in both healthy children and constipated children during maintenance treatment.Asking for defecation signals before scanning should be considered a routine question, and a positive answer should cause postponement of the scan.

Abstract
Studies have shown that the transmission of HIV is most likely to occur via rectal or vaginal routes, and rarely through oral exposure. However, the mechanisms of virus entry at mucosal surfaces remain incompletely understood. Prophylactic strategies against HIV infection may be attainable once gaps in current knowledge are filled. To address these gaps, we evaluated essentially normal epithelial surfaces and mapped the periluminal distribution of CD4+ HIV target cells, including T cells and antigen-presenting cells, and an HIV-binding molecule gp340 that can be expressed by epithelial cells in secreted and cell-associated forms. Immunohistochemistry for CD4, CD16, CD3, CD1a and gp340 in human oral, rectal/sigmoid and cervical mucosal samples from HIV-negative subjects demonstrated that periluminal HIV target cells were more prevalent at rectal/sigmoid and endocervical surfaces lined by simple columnar epithelium, than at oral and ectocervical surfaces covered by multilayered stratified squamous epithelium (p<0.001). gp340 expression patterns at these sites were also distinct and strong in oral minor salivary gland acini and ducts, including ductal saliva, in individual rectum/sigmoid and endocervix periluminar columnar cells, and in ectocervix squamous cells. Only weak expression was noted in the oral non-ductal squamous epithelium. We conclude that periluminal HIV target cells, together with periluminal epithelial cell-associated gp340 appear to be most accessible for HIV transmission at rectal/sigmoid and endocervical surfaces. Our data help define vulnerable structural features of mucosal sites exposed to HIV.

Abstract
INTRODUCTION Constipation has been shown to have a significant impact on lower urinary tract symptoms (LUTS) in children, and treatment of constipation in children with bowel bladder dysfunction (BBD) has been shown to improve or completely resolve LUTS in many cases. Recent studies utilizing trans-abdominal ultrasound (US) to assess stool burden have correlated diagnosis of constipation with US appearance of rectal stool. An US scoring tool was published in 2008 to assess stool burden, showing linear correlation with constipation severity by symptom questionnaire in an outpatient pediatric constipation clinic population. We hypothesized that this US scoring tool would correlate with constipation symptoms in our outpatient pediatric urology population. METHODS In 2010, our pediatric urology outpatient clinic began administering a previously published validated BBD questionnaire to new toilet-trained patients, containing three questions addressing bowel function. Patients in our clinic undergoing trans-abdominal US of the bladder also have assessment of their stool burden by the previously published US scoring tool. We retrospectively reviewed patient charts beginning in June 2013 who had undergone trans-abdominal US of the bladder, gathering data on the first 100 patients with a complete BBD questionnaire and a completed stool burden US scoring tool. RESULTS Chart review of 272 consecutive patients was required to enroll 100 patients with a completed US scoring of stool burden and a completed BBD questionnaire. Of these 272 patients, 225 (82%) had a complete scoring of stool burden during their US examination. BBD questionnaires were complete in 107 of 272 patients (39%). Median patient age was 8.2 years, with 69% of patients being female. The most common diagnosis was incontinence or bladder dysfunction (41%). Only one patient (1%) had constipation as the primary diagnosis for their visit. Linear regression analysis showed no correlation of US score to patient reported frequency of bowel movement, frequency of hard stool, frequency of fecal incontinence, or all three symptoms combined. When investigating the subgroup of patients who had diagnoses of BBD/incontinence, this group was seen to have higher mean symptom scores than the entire cohort as a whole, but US scores were still widely variable and again did not correlate with symptom scores. CONCLUSION US examination has previously been shown to correlate with symptom severity for children with chronic constipation in a pediatric constipation clinic setting. However, in a pediatric urology outpatient clinic setting at our institution, US examination did not correlate with patient reported symptoms.

Abstract
The aim of this study was to compare ultrasonographic assessment of fecal loading in adults with that of computed tomography. Ultrasonography (US) was performed on 43 adult patients immediately after abdominal computed tomography images had identified fecal loading in their colons. In 18 of 43 patients (haustrations-visualized cases), fecal loading was detected as crescent-shaped acoustic shadows associated with haustrations behind the strong echoes off the colon wall. In the remaining 25 patients (haustrations-not-visualized cases), fecal loading was detected as attenuating echoes with multiple high echoic spots behind weak high echoes off the colon wall in 17 patients and similar to those seen in the haustrations-visualized cases but without haustrations in 8 patients. US can be used for qualitative assessment of fecal loading in the colon. This new technique is simple and noninvasive and can be used concomitantly with physical examination to assess severity of constipation.

Abstract
Urinary tract infections (UTIs) represent an important cause of febrile illness in young children and can lead to renal scarring and kidney failure. However, diagnosis and treatment of recurrent UTI in children is an area of some controversy. Guidelines from the American Academy of Pediatrics, National Institute for Health and Clinical Excellence and European Society of Paediatric Radiology differ from each other in terms of the diagnostic algorithm to be followed. Treatment of vesicoureteral reflux and antibiotic prophylaxis for prevention of recurrent UTI are also areas of considerable debate. In this review, we collate and appraise recently published literature in order to formulate evidence-based guidance for the diagnosis and treatment of recurrent UTI in children.

Abstract
CONTEXT In 30% of children with urinary tract anomalies, urinary tract infection (UTI) can be the first sign. Failure to identify patients at risk can result in damage to the upper urinary tract. OBJECTIVE To provide recommendations for the diagnosis, treatment, and imaging of children presenting with UTI. EVIDENCE ACQUISITION The recommendations were developed after a review of the literature and a search of PubMed and Embase. A consensus decision was adopted when evidence was low. EVIDENCE SYNTHESIS UTIs are classified according to site, episode, symptoms, and complicating factors. For acute treatment, site and severity are the most important. Urine sampling by suprapubic aspiration or catheterisation has a low contamination rate and confirms UTI. Using a plastic bag to collect urine, a UTI can only be excluded if the dipstick is negative for both leukocyte esterase and nitrite or microscopic analysis is negative for both pyuria and bacteriuria. A clean voided midstream urine sample after cleaning the external genitalia has good diagnostic accuracy in toilet-trained children. In children with febrile UTI, antibiotic treatment should be initiated as soon as possible to eradicate infection, prevent bacteraemia, improve outcome, and reduce the likelihood of renal involvement. Ultrasound of the urinary tract is advised to exclude obstructive uropathy. Depending on sex, age, and clinical presentation, vesicoureteral reflux should be excluded. Antibacterial prophylaxis is beneficial. In toilet-trained children, bladder and bowel dysfunction needs to be excluded. CONCLUSIONS The level of evidence is high for the diagnosis of UTI and treatment in children but not for imaging to identify patients at risk for upper urinary tract damage. PATIENT SUMMARY In these guidelines, we looked at the diagnosis, treatment, and imaging of children with urinary tract infection. There are strong recommendations on diagnosis and treatment; we also advise exclusion of obstructive uropathy within 24h and later vesicoureteral reflux, if indicated.

Abstract
BACKGROUND Anorectal manometry is a diagnostic method often used in clinical practice for assessing functional anorectal disorders and pelvic floor. The dysfunctional voiding, anorectal and pelvic floor has been considered as contributing factors of the symptoms of overactive bladder. AIM To evaluate the results with anorectal manometry in adult women with clinical and urodynamic diagnostics of overactive bladder. METHODS Twenty-five adult women (mean age 45.5 ± 11.9 years) with clinical and urodynamic diagnostic of overactive bladder underwent anorectal manometry and the results of this assessment were compared to a control group of eighteen women (mean age 33.9 ± 10.7 years) with no urinary or intestinal disorders and without clinical criteria for diagnosis of overactive bladder. RESULTS Paradoxical puborectalis contraction occurred in six patients in the overactive bladder group and none of the controls. There were no significant between group differences in the following manometric parameters: rectoanal inhibitory reflex, rectal sensitivity, maximum tolerable volume, resting pressure, and hypertonia at rest. Mean squeeze pressure was 182.2 mmHg in the overactive bladder group versus 148.1 mmHg in the control group. CONCLUSION Women with overactive bladder had increased incidence of paradoxical puborectalis contraction than women in the control group.

Abstract
BACKGROUND Some patients with Prader-Willi Syndrome (PWS) have symptoms of constipation, but bowel function in PWS has never been systematically evaluated. The aim of the present study was to describe colorectal function in PWS by means of validated techniques. METHODS Twenty-one patients with PWS (14 women, age 17-47 (median = 32)) were evaluated with the Rome III constipation criteria, stool diary, digital rectal examination, rectal diameter assessed from transabdominal ultrasound, and total gastrointestinal transit time (GITT) determined with radio-opaque markers. Results were compared with those of healthy controls. RESULTS Among PWS patients able to provide information for Rome III criteria, 8/20 (40%) fulfilled the criteria for constipation. Most commonly reported symptoms were a feeling of obstructed defecation (8/19, 42%), <3 defecations per week (8/17, 47%), straining during defecation (7/19, 37%) and lumpy or hard stools (6/19, 32%). Rectal diameter did not differ between PWS (median 3.56 centimeters, range 2.24-5.36) and healthy controls (median 3.42 centimeters, range 2.67-4.72) (p = 0.96), but more PWS patients (13/20; 65%) than healthy controls (3/25; 12%) (p < 0.001) had fecal mass in the rectum. Median GITT was 2.0 days (range 0.5-4.4) in PWS versus 1.6 (range 0.7-2.5) in the control group (p = 0.26). However, GITT was >3 days in 5/21 (24%) of PWS and none of the controls (p = 0.047). CONCLUSION Constipation is very common in PWS. Patients with PWS have an increased prevalence of prolonged GITT and palpable stools in the rectum at digital rectal examination.

Abstract
BACKGROUND Constipation is a pediatric problem commonly encountered by many health care workers in primary, secondary, and tertiary care. To assist medical care providers in the evaluation and management of children with functional constipation, the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition were charged with the task of developing a uniform document of evidence-based guidelines. METHODS Nine clinical questions addressing diagnostic, therapeutic, and prognostic topics were formulated. A systematic literature search was performed from inception to October 2011 using Embase, MEDLINE, the Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Clinical Trials, and PsychInfo databases. The approach of the Grading of Recommendations Assessment, Development and Evaluation was applied to evaluate outcomes. For therapeutic questions, quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation system. Grading the quality of evidence for the other questions was performed according to the classification system of the Oxford Centre for Evidence-Based Medicine. During 3 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation, using the nominal voting technique. Expert opinion was used where no randomized controlled trials were available to support the recommendation. RESULTS This evidence-based guideline provides recommendations for the evaluation and treatment of children with functional constipation to standardize and improve their quality of care. In addition, 2 algorithms were developed, one for the infants <6 months of age and the other for older infants and children. CONCLUSIONS This document is intended to be used in daily practice and as a basis for further clinical research. Large well-designed clinical trials are necessary with regard to diagnostic evaluation and treatment.

Abstract
OBJECTIVE To perform a systematic review evaluating the value of abdominal radiography, colonic transit time (CTT), and rectal ultrasound scanning in the diagnosis of idiopathic constipation in children. STUDY DESIGN Eligible studies were those assessing diagnostic accuracy of abdominal radiography, CTT, or rectal ultrasound scanning in children suspected for idiopathic constipation. Methodological quality of the included studies was assessed with the Quality Assessment of studies of Diagnostic Accuracy included in Systematic reviews checklist. RESULTS One systematic review summarized 6 studies on abdominal radiography until 2004. The additional 9 studies evaluated abdominal radiography (n = 2), CTT (n = 3), and ultrasound scanning (n = 4). All studies except two used a case-control study design, which will lead to overestimation of test accuracy. Furthermore, none of the studies interpreted the results of the abdominal radiography, ultrasound scanning, or CTT without knowledge of the clinical diagnosis of constipation. The sensitivity of abdominal radiography, as studied in 6 studies, ranged from 80% (95% CI, 65-90) to 60% (95% CI, 46-72), and its specificity ranged from 99% (95% CI, 95-100) to 43% (95% CI, 18-71). Only one study presented test characteristics of CTT, and two studies presented test characteristics of ultrasonography. CONCLUSION We found insufficient evidence for a diagnostic association between clinical symptoms of constipation and fecal loading on abdominal radiographs, CTT, and rectal diameter on ultrasound scanning in children.

Abstract
Constipation in children is a common health problem affecting 0.7% to 29.6% children across the world. Exact etiology for developing symptoms is not clear in children and the majority is considered to have functional constipation. Alteration of rectal and pelvic floor function through the brain-gut axis seems to play a crucial role in the etiology. The diagnosis is often a symptom-based clinical process. Recently developed Rome III diagnostic criteria looks promising, both in clinical and research fields. Laboratory investigations such as barium enema, colonoscopy, anorectal manometry and colonic transit studies are rarely indicated except in those who do not respond to standard management. Treatment of childhood constipation involves several facets including education and demystification, toilet training, rational use of laxatives for disimpaction and maintenance and regular follow-up. Surgical options should be considered only when medical therapy fails in long standing constipation. Since most of the management strategies of childhood constipation are not evidence-based, high-quality randomized controlled trials are required to assess the efficacy of currently available or newly emerging therapeutic options. Contrary to the common belief that children outgrow constipation as they grow up, a sizable percentage continue to have symptoms beyond puberty.
