Abstract
Introduction Faecal incontinence (FI) is a distressing and often stigmatizing condition characterised as the recurrent involuntary passage of liquid or solid faeces. The reported prevalence of FI exhibits considerable variation, ranging from 7 to 15% in the general population, with higher rates reported among older adults and women. This review explores the pathophysiology mechanisms, the diagnostic modalities and the efficiency of treatment options up to date. Methods A review of the literature was conducted to identify the pathophysiological pathways, investigation and treatment modalities. Result and discussion This review provides an in-depth exploration of the intricate physiological processes that maintain continence in humans. It then guides the reader through a detailed examination of diagnostic procedures and a thorough analysis of the available treatment choices, including their associated success rates. This review is an ideal resource for individuals with a general medical background and colorectal surgeons who lack specialized knowledge in pelvic floor disorders, as it offers a comprehensive understanding of the mechanisms, diagnosis, and treatment of faecal incontinence (FI).

The rectum, anal sphincter and puborectalis muscle show different contraction wave forms during prolonged measurement with a simulated feces. Sci Rep 2024; 14:432. [PMID: 38172283 PMCID: PMC10764324 DOI: 10.1038/s41598-023-50655-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 12/22/2023] [Indexed: 01/05/2024] Open
Abstract
Contractile patterns in rectum, puborectalis muscle and anal sphincter must be studied to understand defecation. Six subjects had contractile waveforms studied with Fecobionics. Symptom questionnaires, balloon expulsion test and anorectal manometry were done for reference. The Fecobionics bag was filled in rectum to urge-to-defecate volume and measurements were done for 4 h before the subjects attempted to evacuate the device. Pressures and bend angle (BA) variations were analyzed with Fast Fourier Transformation. Four normal subjects exhibited low frequency waves (< 0.06 Hz) for pressures and BA. The waves were uncoordinated between recordings, except for rear and bag pressures. Peak wave amplitudes occurred at 0.02-0.04 Hz. Pressures and the BA differed for peak 1 (p < 0.001) and peak 2 amplitudes (p < 0.005). The front pressure amplitude was bigger than the others (rear and BA, p < 0.05; bag, p < 0.005) for peak 1, and bigger than bag pressure (p < 0.005) and BA (p < 0.05) for peak 2. One subject was considered constipated with lower front pressure amplitudes compared to normal subjects and increased amplitudes for other parameters. The sixth subject was hyperreactive and differed from the other subjects. In conclusion, the rectum, anal sphincter and puborectalis muscle showed different contraction waves during prolonged measurements. The data call for larger studies to better understand normal defecation, feces-withholding patterns, and the implications on anorectal disorders.

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
Constipation in children is common and is a frequent cause for healthcare attendances in both primary and secondary care. The Bristol Stool Chart has become ubiquitous as an aid in the diagnosis and treatment of constipation, but many clinicians may not be aware of its origins or strengths and weaknesses. In this article, we outline the history and rationale behind the development of the Bristol Stool Chart and how it should be used in childhood constipation.

Abstract
OBJECTIVES Given a lack of a systematic approach to the use of breath testing in paediatric patients, the aim of this position paper is to provide expert guidance regarding the indications for its use and practical considerations to optimise its utility and safety. METHODS Nine clinical questions regarding methodology, interpretation, and specific indications of breath testing and treatment of carbohydrate malabsorption were addressed by members of the Gastroenterology Committee (GIC) of the European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN).A systematic literature search was performed from 1983 to 2020 using PubMed, the MEDLINE and Cochrane Database of Systematic Reviews. Grading of Recommendations, Assessment, Development, and Evaluation was applied to evaluate the outcomes.During a consensus meeting, all recommendations were discussed and finalised. In the absence of evidence from randomised controlled trials, recommendations reflect the expert opinion of the authors. RESULTS A total of 22 recommendations were voted on using the nominal voting technique. At first, recommendations on prerequisites and preparation for as well as on interpretation of breath tests are given. Then, recommendations on the usefulness of H2-lactose breath testing, H2-fructose breath testing as well as of breath tests for other types of carbohydrate malabsorption are provided. Furthermore, breath testing is recommended to diagnose small intestinal bacterial overgrowth (SIBO), to control for success of Helicobacter pylori eradication therapy and to diagnose and monitor therapy of exocrine pancreatic insufficiency, but not to estimate oro-caecal transit time (OCTT) or to diagnose and follow-up on celiac disease. CONCLUSIONS Breath tests are frequently used in paediatric gastroenterology mainly assessing carbohydrate malabsorption, but also in the diagnosis of small intestinal overgrowth, fat malabsorption, H. pylori infection as well as for measuring gastrointestinal transit times. Interpretation of the results can be challenging and in addition, pertinent symptoms should be considered to evaluate clinical tolerance.

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

Abstract
BACKGROUND This study aimed to evaluate the usefulness, from a therapeutic perspective, of classifying the subtypes of functional childhood constipation using a colon transit time (CTT) test. METHODS A total of 190 children were enrolled in this study, which was based on data collected from a defecation diary, a CTT test, and medical records. RESULTS Polyethylene glycol (PEG) 4000 was prescribed in 51.1% (N = 47/92) of normal transit type constipation cases (NT) and 91.8% (N = 90/98) of abnormal transit type constipation cases (P < 0.001). In terms of the subtype of CTT test, PEG 4000 was prescribed in 51.1% (N = 47/92) of NT cases, 96.2% (N = 25/26) of outlet obstruction type cases (OT), and 90.3% (N = 65/72) of slow transit type cases (ST) (P < 0.001). Polyethylene glycol 4000 was administered in 97.2% (N = 35/36) of the fecal incontinence group and 66.2% (N = 102/154) of the non-fecal incontinence group (P < 0.001). In the non-fecal incontinence group, PEG 4000 was prescribed in 47.3% (N = 40/84) of NT cases, 94.4% (N = 17/18) of OT cases, and 86.5% (N = 45/52) of ST cases (P < 0.001). In the fecal incontinence group, PEG 4000 was prescribed in 87.5% (N = 7/8) of NT cases, 100% (N = 8/8) of OT cases, and 100% (N = 20/20) of ST cases (P = 0.165). CONCLUSIONS Subtype classification of functional constipation based on the CTT test provides important information for the initial choice of drugs in children.

Abstract
OBJECTIVES Solitary rectal ulcer syndrome (SRUS) is said to be rare in children (largest series so far; 55 in children, 116 in adults). We analyzed our experience to look at its clinical presentations, endoscopic appearance, and treatment outcome in a large cohort of children. METHODS Clinical and endoscopic data were collected between 2000 and 2018. Children (18 years or younger) diagnosed to have SRUS on colonoscopy and confirmed by histopathology were included. All children with SRUS were treated with behavioral modification, bulk laxative. Most with ulcer received steroid enema and some sulfasalazine or sucralfate enema. RESULTS The median age of 140 children was 12 (interquartile range [IQR]: 10-14) years, 79% were boys. The median symptom duration was 21 (IQR: 9-36) months. Rectal bleeding was the presenting feature in 131 (93.6%); constipation in 38 (27%); and small, frequent stools in 79 (56%). Most children had features of dyssynergic defecation such as prolonged sitting in the toilet (131, 93.6%), excessive straining (138, 98.6%), a feeling of incomplete evacuation (130, 92.8%), and rectal digitation (71, 50.7%). Rectal prolapse was noted in 24 (17%) cases. Colonoscopy documented rectal ulcer in 101 (72%) [Single: 84]. Over a median follow-up of 6 (IQR: 4-18) months, 27 patients were lost to follow-up and of the remaining 113 cases, 71 (62.8%) showed clinical improvement (healing of ulcer documented in 36/82, 44%). CONCLUSIONS The majority of cases of SRUS presented in second decade with rectal bleeding and features of dyssynergic defecation. Ulcer was noted in three fourths of cases. The outcome of medical treatment with behavioral modification and local therapy was modest.

Abstract
Background/Aims Colon transit time (CTT) test is regarded as the gold standard for evaluating colon transit function. Fluoroscopic defecography (FD) is a dynamic radiologic test to assess anorectal function. The aim is to evaluate the value of FD in constipated children with abnormal CTT test results. Methods Fifty-one children (27 girls) with a mean age of 9.8 ± 3.2 years who met Rome III criteria for constipation and older than 5 years with abnormal CTT test results underwent FD. Results Of 51 children, 27 (52.9%) showed positive findings on FD, including pelvic floor dyssynergia (PFD) (10/27, 37.0%), structural abnormality (15/27, 55.6%) (rectocele 53.3%, intussusception 33.3%, and both 13.4%), and both PFD and rectocele (2/27, 7.4%). In terms of CTT test subtype, of 35 children who had outlet obstruction type in CTT test, 19 (54.2%) had positive findings, including PFD (8/19, 42.1%), structural abnormality (9/19, 47.4%) (rectocele 55.6%, intussusception 22.2%, and both 22.2%), and both PFD and rectocele (2/19, 10.5%). Of the 16 children who had slow transit type of CTT test, 8 (50.0%) had positive findings, including PFD (2/8, 25.0%) and structural abnormality (6/8, 75.0%). Of the 6 children who had structural abnormality, 3 (50.0%) had rectocele and 3 (50.0%) had intussusception. For the 2 children (2/16, 12.5%) who had PFD, puborectalis muscle relax failure was found on FD. Puborectalis muscle relax failure was treated with biofeedback and medication. In the minor abnormalities, medication continued without additional therapeutic modalities. Conclusions FD was valuable for both diagnoses of underlying causes and interpretation of CTT test results in children with abnormal CTT test results. Therefore, this study suggests that FD and CTT tests should be incorporated into logical thinking for constipation in children.

Abstract
PURPOSE To compare the clinical features, diagnostic findings, and medications of children with infrequent bowel movements or fecal soiling. METHODS This study enrolled 333 children (189 male; age range, 1 month to 18 years) diagnosed with functional constipation by Rome III or IV criteria. We classified them into 3 groups (infrequent bowel movement without fecal soiling [G3-a], infrequent bowel movement with fecal soiling [G3-b], and fecal soiling only [G3-c]) and into 2 subgroups of fecal soiling (G2-b) or not (G2-a). Retrospective data on clinical characteristics, colon transit time (CTT) test results, and medications were collected. The Wilcoxon rank-sum test, Kruskal-Wallis test, Chi-square test, and Fisher's exact test were used for the statistical analysis. RESULTS The median age (months) and interquartile range (IQR) was 33 (45) in G3-a, 54 (40) in G3-b, and 73 (48) in G3-c (p<0.0001). G3-c had the latest onset (median, 18; IQR, 18; p=0.0219) and longest symptom duration (24 [24], p=0.0148). PEG 4000 was used in 60.6% (G3-a), 96.8% (G3-b), and 83.2% (G3-c) of patients (p<0.0001). The median age (months) and IQR were 33.0 (45.0) in G2-a and 63.5 (52.5) in G2-b (p<0.0001). G2-b had later onset (median, 12; IQR, 19.5; p=0.0062) and longer symptom duration than G2-a (24 [12], p=0.0070). PEG 4000 was used in 60.6% (G2-a) and 88.3% (G2-b) of children (p<0.0001). No statistically significant intergroup differences were seen in maintenance laxative dose, CTT, or CTT type. CONCLUSION Infrequent bowel movement and fecal soiling represent the advanced stage of chronic functional constipation.

Abstract
Children with chronic idiopathic constipation (CIC) often end up at the surgeon when medical treatments have failed. This opinion piece discusses a recently described pattern of CIC called 'Rapid transit constipation (RTC)' first identified in 2011 as part of surgical workup. RTC was identified using a nuclear medicine gastrointestinal transit study (NMGIT or nuclear transit study) to determine the site of slowing within the bowel and to inform surgical treatment. Unexpectedly, we found that RTC occured in 29% of 1000 transit studies in a retrospective audit. Irritable bowel syndrome (IBS) occurs in 7-21% of the population, with a higher prevalence in young children and with constipation type dominating in the young. While 60% improve with time, 40% continue with symptoms. First-line therapy for IBS in adults is a diet low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols which reduces symptoms in > 70% of patients. In children with functional gastrointestinal disorders, fructose intolerance occurs in 35-55%. Reducing fructose produced significant improvement in 77-82% of intolerant patients. In children with RTC and a positive breath test upon fructose challenge, we found that exclusion of fructose significantly improved constipation, abdominal pain, stool consistency and decreased laxative use. We hypothesise that positive breath tests and improvement of pain and bowel frequency with sugar exclusion diets in RTC suggest these children have IBS-C. These observations raise the possibility that many children with CIC could be treated by reducing fructose early in their diet and this might prevent the development of IBS in later life.

Riahinezhad M, Taleb F, Saneian H, Kazemi S, Khademian M, Farghadani M. Predictive value of colonic transit time indices for differentiating nonnormal from normal sensation in children with chronic functional constipation identified by anorectal manometry. JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2019; 24:106. [PMID: 31949457 PMCID: PMC6950359 DOI: 10.4103/jrms.jrms_460_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/27/2019] [Revised: 07/23/2019] [Accepted: 09/12/2019] [Indexed: 12/04/2022]
Abstract
BACKGROUND Constipation is a common disorder in pediatrics, although the underlying pathogenesis is not fully understood. The current study aimed at evaluating the efficacy of different colonic transit time (CTT) indices for differentiating normal from nonnormal sensation in children with chronic functional constipation identified by anorectal manometry (ARM). MATERIALS AND METHODS In this cross-sectional study, 47 children with chronic idiopathic constipation, aged 5-15 years, were studied. The total and segmental CTTs were estimated by administering multiple radiopaque markers for 6 days and performing a single abdominal radiograph on day 7. Anorectal function was evaluated using manometry with an Arhan probe. The predictive value of CTT indices was evaluated by receiver operating characteristic curve analysis. Area under the curve (AUC) along with 95% confidence interval (CI) as well as sensitivity and specificity was calculated. RESULTS The mean age of the participants was 8.30 ± 2.99 years, with a mean constipation duration of 2.90 ± 0.46; 28 children were identified with nonnormal sensation. The mean values of CTT indices were statistically significantly longer in the nonnormal sensation patients than that in the normal group (P < 0.001). In addition, the mean values of manometry parameters were statistically significantly higher in nonnormal sensation patients than that in normal group (P < 0.01). Among CTT indices, rectosigmoid CTT (AUC [95% CI] =0.999 [0.99-1]; P < 0.001) with sensitivity = 100% and specificity = 94.7% and total CTT (AUC [95% CI] =0.972 [0.93-1] P < 0.001) with sensitivity = 82.3% and specificity = 100% had the highest predictive values for differentiating nonnormal from normal sensation patients. CONCLUSION CTT is a simple and noninvasive technique for classifying patients with constipation. It can be used for identifying children suffering from chronic constipation with nonnormal sensation reliably, instead of ARM. Colonic inertia may be a manifestation of global motility dysfunction. Children with delayed distal colonic transits are more likely to have abnormal defecation dynamics.

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
AIM Increasing evidence exists with respect to the relation between stressful life events and functional constipation (FC). We aimed to investigate the prevalence of FC in Palestinian refugee preschool children and to determine if stress and trauma exposure are risk factors of FC in these children. METHODS From November 2013 until May 2014, a cross-sectional survey was conducted in West Bank, Gaza and Jordan. Mothers of 862 Palestinian refugee children aged 7-48 months were interviewed on defecation pattern, socio-economic factors and the child's exposure to traumatic events. RESULTS Twelve percent of the Palestinian refugee children fulfilled the criteria for FC. The prevalence of constipation was significantly lower in Gaza compared to Jordan (2% vs. 17%, p <0,001). Living in Gaza was associated with lower odds of FC (OR 0,08, 95% CI 0,03-0,20). Trauma exposure was associated with higher odds of FC (OR 1,19, 95% CI 1,06-1,35), however only a small number of children had been exposed to traumatic events. CONCLUSION The overall prevalence of FC in Palestinian preschool children is comparable to prevalence rates among older children worldwide. In this age group stressful life events and trauma exposure seem not to play an important role in the development of FC.

Abstract
INTRODUCTION Indian adults have higher stool frequency and shorter colonic transit time compared to the Western population. Colonic transit time has not been studied well in Indian children. We aimed to compare colonic transit time in normal and constipated children. METHODS In this prospective study, stool characteristics and colonic transit time by radio-opaque markers were studied in healthy children (group A, n = 39) and functional constipation patients (group B, n = 61). Twenty radio-opaque markers were ingested per orally at 0, 12, and 24 h followed by a single abdominal X-ray at 36 h. Total and segmental colonic transit times were calculated using the standard formula. RESULTS Stool frequency per week and consistency were significantly different between group A (9 [2.5-17] years) vs. group B (4.5 [2-14] years), 7 (7-14) vs.1 (1-2), and Bristol type 4 (3-5) vs. type 2 (1-3). Total colonic transit time of groups A and B was 16.2 (0.6-36) vs. 22.8 (1.8-35.4) hours; p = 0.003. Ninety-fifth percentile (upper limit of normal) cutoff derived from group A was 31.8 h. Ninety-two percent of group B had colonic transit < 95th percentile of normal healthy children. Despite 8% with colonic transit > 95th percentile, all group B patients responded well to standard therapy with laxatives. CONCLUSION Indian children have significantly higher stool frequency and shorter colonic transit time, which are different compared to the reported figures from the West. Most of the Indian children with functional constipation had normal colonic transit time.

Abstract
Constipation is a common childhood problem, but an anatomic or physiologic cause is identified in fewer than 5% of children. By definition, idiopathic constipation is a diagnosis of exclusion. Careful clinical evaluation and thoughtful use of imaging and other testing can help exclude specific causes of constipation and guide therapy. Medical management with laxatives is effective for the majority of constipated children. For those patients unresponsive to medications, however, several surgical options can be employed, including anal procedures, antegrade colonic enemas, colorectal resection, and intestinal diversion. Judicious use of these procedures in properly selected patients and based on appropriate preoperative testing can lead to excellent outcomes. This review summarizes the surgical options available for managing refractory constipation in children and provides guidance on how to choose the best procedure for a given patient.

Abstract
BACKGROUND Transcutaneous electrical stimulation (TES) for one to two months has produced some improvement in treatment-resistant slow-transit constipation (STC) in children. Optimal parameters for treatment are not known. It is possible that more improvement would occur with stimulation for longer. This study examined the effectiveness of stimulation for six months. METHODS Children with STC confirmed by nuclear transit study (NTS) were enrolled prospectively. All had chronic constipation for greater than two years and had failed medical treatment. TES was performed for one hour/day for six months using the INF 4160 (Fuji Dynamics) portable stimulator and 4 cm × 4 cm electrodes near the belly button and on the back. Families kept bowel diaries and completed PEDSQLCore QOL (4.0) questionnaires before and at end of treatment. RESULTS Sixty-two children (34 females; seven years, 2-16 year) with STC were studied. Defecation frequency increased in 57/62 (91%, mean ± SEM pre- 1.49 ± 0.20 vs. post- 3.25 ± 0.25 defecation/week, p < 0.0001) with the number with ≥3BA increasing from 6 to 37 (10-59%). Soiling frequency decreased from 4.8 to 1.1 days/week (p <0.001). Abdominal pain decreased from 1.7 to 0.3 days/week (<0.0001), and spontaneous urge to defecate improved. Quality of life (p < 0.01), mean transit index and gastric emptying on NTS improved (p < 0.005). CONCLUSION Treatment-resistant STC responds to TES using interferential current across the abdomen when given daily for many months. Battery operated stimulators allowed stimulation at home for an hour each day. Stimulation for six months produced clinically significant improvement in defecation frequency, soiling, abdominal pain, urge to defecate, and quality of life in half of these chronic patients.

Abstract
Abstract
The term ‘encopresis’, derived from ancient Greek ἐγκόπρησις / egkóprēsis, which means stool, was first introduced in 1926 by Weissenberg to describe the loss of stool in underwear as the faecal equivalent of enuresis. The soiling of underwear is defined as the accidental passage of very small amounts of faeces into underpants. Quantitatively, the content of stool between encopresis and soiling is difficult to determine, and it is especially difficult for parents assess it. Therefore, a new term was adopted – faecal incontinence – that encompasses both encopresis and soiling.
Faecal incontinence is defined as the discharge of faeces in socially awkward situations at least once per month in children ≥ 4 years old. In approximately 95% of cases, faecal incontinence in children is not organic in origin, but instead appears as a functional gastrointestinal disorder. In 80% of children with functional faecal incontinence, the symptoms are associated with functional constipation. The remaining 20% of the cases involve no signs of faecal retention and are defined as non-retentive functional faecal incontinence.
This paper aims to present the latest findings within this area of paediatric gastroenterology.

Is Hydrogen Breath Test with Lactulose Feasible for Measuring Gastrocecal Transit in Critically Ill Children? Pilot Study about Modification of the Technique. BIOMED RESEARCH INTERNATIONAL 2017; 2017:5878659. [PMID: 28246601 PMCID: PMC5299192 DOI: 10.1155/2017/5878659] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2016] [Revised: 12/18/2016] [Accepted: 12/28/2016] [Indexed: 12/26/2022]
Abstract
Introduction. Gastrocecal transit time (GCTT) can be measured by exhaled hydrogen after lactulose intake (lactulose-eH2 test). The objectives were to assess whether it is possible to carry out this test in critically ill children with and without mechanical ventilation (MV) and to analyze whether the results are consistent with clinical findings. Methods. Patients admitted to the Pediatric Intensive Care Unit (PICU) for more than 3 days were included. Those with gastrointestinal disease prior to admission were excluded. A modified technique to obtain eH2 from the ventilator tubes was performed. Results. Sixteen patients (37.5% boys) with a median age of 19 (5-86.5) months were included. Five patients (31.2%) were breathing spontaneously but lactulose-eH2 test could not be performed while it could be performed successfully in the 11 patients with MV. Seven patients (63.3%) did not show an eH2 peak. The other 4 showed a median time of 130 min (78.7-278.7 min) from lactulose intake to a 10 ppm eH2 peak. Children with an eH2 peak had intestinal movements earlier [6.5 (1.5-38.5) versus 44 (24-72) hours p = 0.545]. Conclusion. Although the designed adaption is useful for collecting breath samples, lactulose-eH2 test may not be useful for measuring GCTT in critically ill children.

Abstract
PURPOSE To evaluate the correlation between colon transit time (CTT) test value and initial maintenance dose of polyethylene glycol (PEG) 4000 or lactulose. METHODS Of 415 children with chronic functional constipation, 190 were enrolled based on exclusion criteria using the CTT test, defecation diary, and clinical chart. The CTT test was performed with prior disimpaction. The laxative dose for maintenance was determined on the basis of the defecation diary and clinical chart. The Shapiro-Wilk test and Pearson's and Spearman's correlations were used for statistical analysis. RESULTS The overall group median value and interquartile range of the CTT test was 43.8 (31.8) hours. The average PEG 4000 dose for maintenance in the overall group was 0.68±0.18 g/kg/d; according to age, the dose was 0.73±0.16 g/kg/d (<8 years), 0.53±0.12 g/kg/d (8 to <12 years), and 0.36±0.05 g/kg/d (12 to 15 years). The dose of lactulose was 1.99±0.43 mL/kg/d (<8 years) or 1.26±0.25 mL/kg/d (8 to <12 years). There was no significant correlation between CTT test value and initial dose of laxative, irrespective of the subgroup (encopresis, abnormal CTT test subtype) for either laxative. Even in the largest group (overall, n=109, younger than 8 years and on PEG 4000), the correlation was weak (Pearson's correlation coefficient [R]=0.268, p=0.005). Within the abnormal transit group, subgroup (n=73, younger than 8 years and on PEG 4000) correlation was weak (R=0.267, p=0.022). CONCLUSION CTT test value cannot predict the initial maintenance dose of PEG 4000 or lactulose with linear correlation.

Abstract
Functional constipation (FC) is a significant health problem in children and contrary to common belief, has serious ramifications on the lives of children and their families. It is defined by the Rome criteria which encourage the use of multiple clinical features for diagnosis. FC in children has a high prevalence (0.7%-29%) worldwide, both in developed and developing countries. Biopsychosocial risk factors such as psychological stress, poor dietary habits, obesity and child maltreatment are commonly identified predisposing factors for FC. FC poses a significant healthcare burden on the already overstretched health budgets of many countries in terms of out-patient care, in-patient care, expenditure for investigations and prescriptions. Complications are common and range from minor psychological disturbances, to lower health-related quality of life. FC in children also has a significant impact on families. Many paediatric clinical trials have poor methodological quality, and drugs proved to be useful in adults, are not effective in relieving symptoms in children. A significant proportion of inadequately treated children have similar symptoms as adults. These factors show that constipation is an increasing public health problem across the world with a significant medical, social and economic impact. This article highlights the potential public health impact of FC and the possibility of overcoming this problem by concentrating on modifiable risk factors rather than expending resources on high cost investigations and therapeutic modalities.

Abstract
Constipation, defined as delay or difficulty in defecation, present for 2 or more weeks, is a common problem encountered by both primary and specialty medical providers. There are no randomized controlled trials on the use of antegrade enemas in the pediatric population. Most published papers are based on the experience at a particular center. The aim of this article is to describe the pathophysiology of constipation, review the contribution of colonic manometry to the diagnosis of constipation, summarize the advancements in the management of constipation through the use of antegrade enemas, and study the outcomes of cecostomy at different centers. This study is a comprehensive literature review generated by computerized search of literature, supplemented by review of monographs and textbooks in pathology, gastroenterology, and surgery. Literature search was performed using the publications from 1997 to 2012. The search included publications of all types presenting or reviewing data on cecostomy. The antegrade continence enema is a therapeutic option for defecation disorders when maximal conventional therapy is not successful. Symptoms of defecation disorders in children with different underlying etiologies improve significantly after a cecostomy is created. In addition, there is a benefit on the patients' physical activity, healthcare utilization, and general well-being. Based on the review of published literature it seems that antegrade enemas are a successful therapeutic option in children with severe constipation and/or fecal incontinence. With the advent of cecostomy buttons, patient compliance and the overall cosmetic appearance have improved.

Abstract
Background/Aims Studies in adults suggest that constipation may not be a purely colonic pathology and may be a component of a generalized gastrointestinal (GI) motor disorder in which proximal GI motility can be impaired. Pediatric data are scarce, and the natural history of the disorder remains undefined. We aimed to evaluate gallbladder motility in a subset of Asian children with chronic functional constipation. Methods Abdominal ultrasound was performed on 105 children, including 55 patients (aged 3 to 13 years) with chronic functional constipation who met the inclusion criteria and 50 age- and gender-matched controls. The gallbladder contractility index was calculated based on the preprandial and postprandial gallbladder areas. Preprandial and postprandial values for gallbladder volume and wall thickness were evaluated. Results The mean value of the contractility index for the patients (15.77±24.68) was significantly lower than the mean value for the controls (43.66±11.58) (p=0.001). The mean postprandial gallbladder volumes and areas were larger in children with gallbladder hypomotility (p<0.05). The mean duration of constipation (4.8 months) was significantly higher (p=0.004) in the children with gall-bladder hypomotility. Conclusions Gallbladder motility is significantly impaired in children with chronic functional constipation. This study contributes to the understanding of the underlying pathophysiology, which will enable advancement in and improved management of children with chronic constipation and associated gallbladder hypomotility.

Abstract
INTRODUCTION Many theories have been proposed for the coexistence of constipation and lower urinary tract dysfunction (LUTD), such as bladder compression from a distended rectum and stimulation of sacral reflexes from a full rectum. In these cases, successful treatment of constipation should result in resolution of bladder symptoms. Some children have refractory constipation and others respond well to treatment, but once treatment is discontinued most children relapse back into their constipation. This may indicate the existence of a defect in colon motility, with a persistent peristalsis problem. The existence of a common neuromuscular disorder should be the base for both bladder and bowel dysfunction (BBD). OBJECTIVE To study colonic transit time (CTT) in children and adolescents with refractory constipation and lower urinary tract symptoms (LUTS). MATERIALS AND METHODS A total of 15 children (mean age 9.7 years) with refractory constipation and LUTS were evaluated with: standardized medical history; physical examination; bladder and bowel diaries; Bristol stool scale; Rome III criteria; Dysfunctional Voiding Scoring System (DVSS); ultrasound examination of the kidneys and urinary tract, and measurement of rectal diameter; urodynamic evaluation; and a CTT study using radiopaque markers. RESULTS Urodynamic features were abnormal in 13 out of 15 children: 10 (66.7%) presented with detrusor overactivity (DO) and voiding dysfunction (VD), two (16.7%) had isolated DO, and one (8.3%) had a VD. The CTT study was abnormal in 12 out of 15 children: nine (60%) presented with slow transit constipation, three (20%) had outlet obstruction, and three (20%) had a normal CTT study. When comparing CTT and LUTD, nine (100%) children with slow transit constipation (STC) and three (50%) with no STC had DO (P = 0.04). Seven (77.8%) children with STC and three (50%) with no STC had VD (P = 0.29). The DVSS scores ranged from 6 to 21. The subgroup with STC had a DVSS score that was significantly higher than that of the subgroup with noF STC (Figure). DISCUSSION The present study showed a high prevalence of STC in children and adolescents with refractory constipation and LUTS. This was in accordance with previous studies that have demonstrated a rate of 50-60% of STC in children with refractory constipation. In addition, DO was found to be associated with STC, which raises the chance for the existence of a common neuromuscular disorder to be the base for both bladder and bowel dysmotility. The limitation of this study was the number of participants. CONCLUSIONS The present study demonstrated an association between DO and STC.

Abstract
Slow-transit constipation (STC) is a newly described subtype of intractable constipation in children which we originally identified with deficiency of substance P in axons supplying the proximal colonic muscle. When nuclear transit studies became available, the patients were found to have slow proximal colonic transit, and responded to antegrade enemas. Using the appendicostomy, we found that there was reduced frequency in propagating sequences throughout the colon. We began testing whether transcutaneous electrical stimulation (TES) could improve motility and symptoms, and over several trials have now shown that TES is remarkably effective in treating children with STC, with long-lasting effects. TES holds promise for treating STC, as well as a range of gastrointestinal motility disorders.

Abstract
BACKGROUND Constipation is one of the most common chronic digestive complaints. Gastrointestinal transit studies have divided it into three patterns: normal transit, slow transit constipation (STC), and outlet obstruction. It has been demonstrated that STC patients respond poorly to standard therapies, and the etiology of STC remains poorly understood. Animal studies have also shown that fatty acid amide hydrolase (FAAH) controls intestinal motility through its putative receptors or non-receptor-mediated pathways. However, the role of FAAH in STC has not been elaborated. METHODS A case series was carried out on thirty-two STC patients fulfilling the Rome II criteria and on 24 controls. All of the subjects underwent a laparotomy in Shengjing Hospital. Colonic specimens were obtained and used for FAAH expression analysis, enzyme activity assay, and cannabinoid detection. RESULTS FAAH immunoreactivity occurred in the enteric neurons and in the surface epithelial and glands. The expression level and enzyme activity of FAAH in the STC group were both significantly lower than those in the control group (P < 0.05). The amounts of anandamide, 2-arachidonylglycerol, and palmitoylethanolamide, which are negatively correlated with enzyme activity, were significantly higher in the constipation group than that in the control group. In the STC group, cannabinoid receptor type 1 immunoreactivity occurred predominantly in the submucosal and myenteric fibers that were obviously strong and wave-like in their appearance. Enteric ganglions decreased or disappeared. CONCLUSIONS The tone of the enteric cannabinoids system is disturbed in STC, and the decreased enteric FAAH activity contributes to colonic inertia in STC.

Abstract
The prevalence of functional constipation in children is almost 10%. The etiology is multifactorial and not fully understood. In the majority of cases, there is no organic explanation for the symptoms. However, it is very important to exclude organic causes, particularly in neonates and infants. There are warning symptoms, such as delayed passage of meconium, bilious vomiting and abdominal distention that should prompt further investigations. Fecal incontinence is a very common symptom secondary to fecal impaction. The first-line treatment for both disimpaction and maintenance is use of laxatives. Parental education is extremely important. There are very limited data on surgical approaches for functional constipation.

Abstract
The objective of this study was to evaluate gastric emptying (GE) in pediatric
patients with functional constipation. GE delay has been reported in adults with
functional constipation. Gastric emptying studies were performed in 22 children
with chronic constipation, fecal retention and fecal incontinence, while
presenting fecal retention and after resuming regular bowel movements. Patients
(18 boys, median age: 10 years; range: 7.2 to 12.7 years) were evaluated in a
tertiary pediatric gastroenterology clinic. Gastric half-emptying time of water
(reference range: 12 ± 3 min) was measured using a radionuclide technique
immediately after first patient evaluation, when they presented fecal impaction
(GE1), and when they achieved regular bowel movements
(GE2), 12 ± 5 weeks after GE1. At study admission, 21
patients had reported dyspeptic symptoms, which were completely relieved after
resuming regular bowel movements. Medians (and interquartile ranges) for
GE1 and GE2 were not significantly different [27.0
(16) and 27.5 (21) min, respectively (P = 0.10)]. Delayed GE seems to be a
common feature among children with chronic constipation and fecal retention.
Resuming satisfactory bowel function and improvement in dyspeptic symptoms did
not result in normalization of GE data.

Abstract
BACKGROUND Faecal incontinence (FI) in children is a significant gastrointestinal problem, with great personal and social impacts. It is characterised by recurrent loss of faecal matter into the underwear. Both functional and organic causes contribute to its aetiology with the former predominating. AIM To review the epidemiology, pathophysiology, clinical evaluation and management of functional faecal incontinence in children. METHODS A PubMed search was conducted using search terms f(a)ecal incontinence, and encopresis. Articles on epidemiology, pathophysiology, clinical evaluation, investigation and management of functional FI in children were retrieved and assessed. RESULTS Community prevalence of this distressing problem ranges from 0.8% to 7.8% globally. Male: female ratio varies from 3:1 to 6:1. The diagnosis of FI is often based on established clinical criteria. The majority (82%) have constipation associated functional FI. Biopsychosocial factors play a crucial role in the pathogenesis. Limited physiological testing of anorectal function is recommended in the diagnostic procedures, particularly in children with atypical symptoms and possible organic disorders. Management of FI needs a multidisciplinary approach which includes establishment of an effective doctor-patient partnership, understanding the underlying mechanisms, pharmacotherapy and behavioural treatment. Approximately 15% of children with functional nonretentive faecal incontinence (FNRFI) had the same symptoms at the age of 18 years. CONCLUSION Significant therapeutic advances have been made for retentive faecal incontinence, but treatment options for functional nonretentive faecal incontinence are limited. Limited long-term outcome data show that the majority outgrow faecal incontinence. A substantial proportion of children progress to adulthood with faecal incontinence.

Abstract
BACKGROUND AND AIMS In slow-transit constipation (STC) pancolonic manometry shows significantly reduced antegrade propagating sequences (PS) and no response to physiological stimuli. This study aimed to determine whether transcutaneous electrical stimulation using interferential current (IFC) applied to the abdomen increased colonic PS in STC children. METHODS Eight children (8-18 years) with confirmed STC had 24-h colonic manometry using a water-perfused, 8-channel catheter with 7.5 cm sidehole distance introduced via appendix stomas. They then received 12 sessions (20 min/3× per week) of IFC stimulation (2 paraspinal and 2 abdominal electrodes), applied at a comfortable intensity (<40 mA, carrier frequency 4 kHz, varying beat frequency 80-150 Hz). Colonic manometry was repeated 2 (n=6) and 7 (n=2) months after IFC. RESULTS IFC significantly increased frequency of total PS/24h (mean ± SEM, pre 78 ± 34 vs post 210 ± 62, p=0.008, n=7), antegrade PS/24h (43 ± 16 vs 112 ± 20, p=0.01) and high amplitude PS (HAPS/24h, 5 ± 2:10 ± 3, p=0.04), with amplitude, velocity, or propagating distance unchanged. There was increased activity on waking and 4/8 ceased using antegrade continence enemas. CONCLUSIONS AND INFERENCES Transcutaneous IFC increased colonic PS frequency in STC children with effects lasting 2-7 months. IFC may provide a treatment for children with treatment-resistant STC.

Abstract
Human defecation involves integrated and coordinated sensorimotor functions, orchestrated by central, spinal, peripheral (somatic and visceral), and enteric neural activities, acting on a morphologically intact gastrointestinal tract (including the final common path, the pelvic floor, and anal sphincters). The multiple factors that ultimately result in defecation are best appreciated by describing four temporally and physiologically fairly distinct phases. This article details our current understanding of normal defecation, including recent advances, but importantly identifies those areas where knowledge or consensus is still lacking. Appreciation of normal physiology is central to directed treatment of constipation and also of fecal incontinence, which are prevalent in the general population and cause significant morbidity.

Abstract
BACKGROUND Faecal incontinence is a common and potentially distressing disorder of childhood. OBJECTIVES To assess the effects of behavioural and/or cognitive interventions for the management of faecal incontinence in children. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Trials Register (searched 28 October 2011), which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and CINAHL, and handsearching of journals and conference proceedings, and the reference lists of relevant articles. We contacted authors in the field to identify any additional or unpublished studies. SELECTION CRITERIA Randomised and quasi-randomised trials of behavioural and/or cognitive interventions with or without other treatments for the management of faecal incontinence in children. DATA COLLECTION AND ANALYSIS Reviewers selected studies from the literature, assessed study quality, and extracted data. Data were combined in a meta-analysis when appropriate. MAIN RESULTS Twenty one randomised trials with a total of 1371 children met the inclusion criteria. Sample sizes were generally small. All studies but one investigated children with functional faecal incontinence. Interventions varied amongst trials and few outcomes were shared by trials addressing the same comparisons.Combined results of nine trials showed higher rather than lower rates of persisting symptoms of faecal incontinence up to 12 months when biofeedback was added to conventional treatment (OR 1.11 CI 95% 0.78 to 1.58). This result was consistent with that of two trials with longer follow-up (OR 1.31 CI 95% 0.80 to 2.15). In one trial the adjunct of anorectal manometry to conventional treatment did not result in higher success rates in chronically constipated children (OR 1.40 95% CI 0.72 to 2.73 at 24 months).In one small trial the adjunct of behaviour modification to laxative therapy was associated with a significant reduction in children's soiling episodes at both the three month (OR 0.14 CI 95% 0.04 to 0.51) and the 12 month assessment (OR 0.20 CI 95% 0.06 to 0.65). AUTHORS' CONCLUSIONS There is no evidence that biofeedback training adds any benefit to conventional treatment in the management of functional faecal incontinence in children. There was not enough evidence on which to assess the effects of biofeedback for the management of organic faecal incontinence. There is some evidence that behavioural interventions plus laxative therapy, rather than laxative therapy alone, improves continence in children with functional faecal incontinence associated with constipation.

Abstract
Constipation in children is an often long-lasting pediatric functional gastrointestinal disorder with a worldwide prevalence varying between 0.7% and 29.6%, and estimated health-care costs of US$3.9 billion per year in the USA alone. The pathophysiology of childhood constipation is multifactorial and remains incompletely understood; however, withholding of stools, starting after an experience of a hard, painful, or frightening bowel movement is the most common cause found in children. A thorough medical history and physical examination, including a rectal examination in combination with a bowel diary, is sufficient in the majority of cases to diagnose constipation. The current standard treatment consists of education, toilet training, disimpaction, maintenance therapy and long-term follow-up. In the past decade, well-designed treatment trials in the pediatric population have emerged and long-term outcome studies have been completed. This Review summarizes the current knowledge of the clinical aspects of childhood constipation, including pathogenesis, diagnosis and treatment, with particular emphasis on the latest available data.

Abstract
PURPOSE Transcutaneous electrical stimulation (TES) speeds up colonic transit in children with slow-transit constipation (STC). This study examined if concurrent upper gastrointestinal dysmotility (UGD) affected response to TES. METHODS Radio-nuclear transit studies (NTS) were performed before and after TES treatment of STC as part of a larger randomised controlled trial. UGD was defined as delayed gastric emptying and/or slow small bowel transit. Improvement was defined as increase of ≥1 Geometric Centre (median radiotracer position at each time [small bowel = 1, toilet = 6]). RESULTS Forty-six subjects completed the trial, 34 had NTS after stimulation (21 M, 8-17 years, mean 11.3 years; symptoms >9 years). Active stimulation increased transit in >50% versus only 25% with sham (p = 0.04). Seventeen children also had UGD. In children with STC and either normal upper GI motility (NUGM) and UGD, NTS improved slightly after 1 month (57 vs. 60%; p = 0.9) and more after 2 months (88 vs. 40%; p = 0.07). However, mean transit rate significantly increased with NUGM, but not UGD (5.0 ± 0.2: 3.6 ± 0.6, p < 0.01). CONCLUSION Transcutaneous electrical stimulation was beneficial for STC, with response weakly associated with UGD. As measured by NTS, STC children with NUGM responded slightly more, but with significantly greater increased transit compared to those with UGD. Higher numbers are needed to determine if the difference is important.

Abstract
OBJECTIVES The aim of the study was to determine the frequency of functional constipation according to the Rome III criteria in children with morbid obesity and to evaluate by measuring colonic transit times (CTTs) whether decreased colonic motility is present in these children. PATIENTS AND METHODS Ninety-one children with morbid obesity ages 8 to 18 years, entering a prospective, randomized controlled study evaluating the effect of an outpatient versus inpatient treatment program of obesity, participated. All of the children filled out a standardized questionnaire regarding their bowel habits, and CTTs were measured using radioopaque markers. Food diaries were also recorded to evaluate their diet. RESULTS A total of 19 children (21%) had functional constipation according to the Rome III criteria, whereas 1 child had functional nonretentive fecal incontinence. Total CTT exceeded 62 hours in only 10.5% of the children with constipation, and among them, 2 had a total CTT of >100 hours. In the nonconstipated group 8.3% had a delayed CTT. Furthermore, no difference was found between the diet of children with or without constipation, specifically not with respect to fiber and fat intake. CONCLUSIONS Our study confirms a high frequency of functional constipation in children with obesity, using the Rome III criteria. However, abnormal colonic motility, as measured by CTT, was delayed in only a minority of patients. No relation was found between constipation in these children and fiber or fat intake.

Abstract
Constipation is a common and distressing condition with major morbidity, health care burden, and impact on quality of life. Colonic motor dysfunction remains the leading hypothesis to explain symptom generation in the most severe cases of chronic constipation and physiological testing plays a role in identifying the colonic dysmotility and the subsequent patient management. Measurement of colonic motor patterns and transit has enhanced our knowledge of normal and abnormal colonic motor physiology. The scope of this review encompasses the latest findings that improve our understanding of the motility disorders associated with colonic dysfunction in both the paediatric and adult population suffering from constipation.

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.

Abstract
We report a misleading outcome of colonic transit time (CTT) assessment in an adolescent girl with functional constipation. We found prolonged total and right segmental CTT despite high doses of oral polyethylene glycol 4000 and repeated treatment with polyethylene glycol-electrolyte solution (Klean-Prep®) by nasogastric tube. A colonoscopy aiming at disimpaction of a possible faecal mass revealed an empty colon with dozens of radio-opaque markers adhered to the colonic wall. This report shows that the result of a CTT cannot be accepted blindly. Especially the clustering of many markers within narrow margins might point at entrapment of markers in mucus against the colonic wall.

Abstract
BACKGROUND Slow-transit constipation (STC) is recognized in children but the etiology is unknown. Abnormalities in substance P (SP), vasoactive intestinal peptide (VIP) and nitric oxide (NO) have been implicated. The density of nerve fibers in circular muscle containing these transmitters was examined in colon from children with STC and compared to other pediatric and adult samples. METHODS Fluorescence immunohistochemistry using antibodies to NO synthase (NOS), VIP and SP was performed on colonic biopsies (transverse and sigmoid colon) from 33 adults with colorectal cancer, 11 children with normal colonic transit and anorectal retention (NAR) and 51 with chronic constipation and slow motility in the proximal colon (STC). The percentage area of nerve fibers in circular muscle containing each transmitter was quantified in confocal images. KEY RESULTS In colon circular muscle, the percentage area of nerve fibers containing NOS > VIP > SP (6 : 2 : 1). Pediatric groups had a higher density of nerve fibers than adults. In pediatric samples, there were no regional differences in NOS and VIP, while SP nerve fiber density was higher in sigmoid than proximal colon. STC children had lower SP and VIP nerve fiber density in the proximal colon than NAR children. Twenty-three percent of STC children had low SP nerve fiber density. CONCLUSIONS & INFERENCES There are age-related reductions in nerve fiber density in human colon circular muscle. NOS and VIP do not show regional variations, while SP nerve fiber density is higher in distal colon. 1/3 of pediatric STC patients have low SP or VIP nerve fiber density in proximal colon.

Abstract
PURPOSE The aim of study was to evaluate if pelvic ultrasound can be useful in managing children with chronic idiopathic constipation. METHODS A total of 270 children with idiopathic chronic constipation were enrolled in the study. At baseline and at monthly checkups children were evaluated by clinical score and pelvic ultrasound (US). Patients have been divided in 2 groups, based on pelvic US results: group A with a rectal diameter >3 cm, group B with a rectal diameter <3 cm or rectum not visualized. Both groups were subsequently randomly divided in two subgroups (A1, A2, B1, B2) on the basis of the prescribed treatment (disimpaction for the first week and daily laxative or only daily laxative). RESULTS After 1 month of therapy all clinical features improved in group A1 and at pelvic US, rectal size reduced and became not visualized; group A2 showed poor clinical response and transverse diameter of rectum did not modify significantly; B1 and B2 groups showed significant improvement only after 2-3 months. CONCLUSIONS Rectal disimpaction is necessary only in presence of MR. Pelvic US is a useful to diagnose MR and to set up the most appropriate treatment protocol for different chronic constipation cases.

Abstract
OBJECTIVE Behavior problems are common in children with functional constipation. This study assessed the prevalence of overall, internalizing, and externalizing behavior problems in children with functional constipation and explored which clinical characteristics of constipation are associated with these behavior problems. METHODS Children who had functional constipation, were aged 4 to 18 years, and were referred to the gastrointestinal outpatient clinic at the Emma Children's Hospital were eligible for enrollment. This study made use of baseline data of 133 children who participated in a randomized, controlled trial that evaluated the clinical effectiveness of behavioral therapy compared with conventional treatment. Prevalence of behavior problems was assessed by the Child Behavior Checklist. Univariate and multivariate logistic regression models were used to test the association between clinical characteristics and behavior problems. RESULTS The prevalence rate of overall, internalizing, and externalizing behavior problems was considerable: respectively 36.8%, 36.1%, and 27.1% compared with 9% in the Dutch norm population. A long duration of treatment was found to have the strongest association with overall and externalizing behavior problems in children with constipation. Children with constipation and nighttime urinary incontinence have an increased risk for having overall behavior problems. Fecal incontinence and the production of large stools seemed to be exclusively related to externalizing behavior problems. CONCLUSIONS Behavior problems are common in children who have constipation and are referred to gastrointestinal outpatient clinics, suggesting that a behavioral screening should be incorporated into the diagnostic workup of children with constipation.

Abstract
Gastrointestinal motility disorders in their most severe forms may directly lead to intestinal failure. Abnormal motor function may also contribute to the overall gut dysfunction of children who have other underlying gastrointestinal diseases, such as Hirschsprung disease or gastroschisis. Understanding the extent and the severity of the dysmotile segments has direct therapeutic and prognostic implications. Our ability to study gastrointestinal motility has greatly improved in the past few years, with the development of less-invasive diagnostic tests. Optimal treatment of children with intestinal motility disorders relies on a multidisciplinary approach, which focuses on optimizing nutrition, improving gastrointestinal motility, and reducing psychosocial disability. Patient education is important to avoid aggravations of symptoms caused by dietary indiscretions.

Abstract
BACKGROUND & AIMS Increased rectal compliance has been proposed to contribute to pediatric functional constipation (FC). We evaluated the clinical relevance of increased rectal compliance and assessed whether regular use of enemas improves rectal compliance in children with FC. METHODS A prospective longitudinal study was conducted on children (8-18 years old) with FC. Pressure-controlled rectal distensions were performed at baseline and at 1 year. Rectal compliance was categorized into 3 groups: normal, moderately increased, or severely increased. Patients were randomly assigned to groups given conventional therapy or rectal enemas and conventional therapy. Clinical success was defined as >or=3 spontaneous defecations per week and fecal incontinence <1 per week. RESULTS Baseline measurements were performed in 101 children (11.0 +/- 2.1 years); rectal compliance was normal in 36%, moderately increased in 40%, and severely increased in 24%. Patients with severely increased rectal compliance had lower defecation frequency (P = .03), more fecal incontinence (P = .04), and more rectal fecal impaction (P < .001). After 1 year, success values were similar between groups: 42% normal, 41% moderately increased, and 40% with severely increased compliance. Barostat studies performed after 1 year in 80 children (37 conventional therapy and 43 rectal enemas in addition to conventional therapy) revealed that rectal compliance had not changed in either group and had not improved in successfully treated patients. CONCLUSIONS Constipated children with severely increased rectal compliance have severe symptoms. However, increased rectal compliance is not related to treatment failure. Regular use of enemas to avoid rectal fecal impaction does not improve rectal compliance in pediatric FC.

Daily transabdominal electrical stimulation at home increased defecation in children with slow-transit constipation: a pilot study. J Pediatr Surg 2009; 44:2388-92. [PMID: 20006033 DOI: 10.1016/j.jpedsurg.2009.07.063] [Citation(s) in RCA: 50] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2009] [Accepted: 07/31/2009] [Indexed: 01/14/2023]
Abstract
PURPOSE Transcutaneous electrical stimulation (TES) (3 sessions/wk) over the abdomen stimulated bowel functions in a randomized controlled trial. This pilot study assessed whether daily TES at home with a safe, portable machine would be possible and more efficacious than trial results. METHODS Eleven patients (6 male/5 female; mean age, 14 years; range, 12-18 years) with slow-transit constipation who relapsed or responded poorly in the trial were recruited (11 +/- 5 months later). An EPM-IF-4160 (Fuji Dynamics, Hong Kong) portable machine (sine waveform, 4 kHz carrier frequency, 80-160 Hz beat frequency, intensity <33 mA) delivering interferential current (2 electrodes over epigastrium + 2 over kidneys) was applied 1 hour daily at home. Continence diaries were kept for 1 month before and 2 months during treatment. RESULTS All children completed more than 1 month of treatment after baseline recording. Defecation increased in 9 of 11 children, and soiling decreased in 4 of 11 children. There was a significant increase in total episodes of defecation per week (mean +/- SD, 2.5 +/- 2.1 vs 6.7 +/- 4.4; P = .008) and a nonsignificant decrease in soiling (3.8 +/- 1.6 vs 1.1 +/- 0.5 episodes/wk, P = .1). Daily stimulation does not affect abdominal pain. No adverse events occurred. CONCLUSIONS Daily TES at home is safe and significantly improved bowel function in children who did not respond to 3 times per week of TES. Home TES may be a novel treatment of intractable slow transit constipation, avoiding hospital visits.

Abstract
BACKGROUND AND AIM It appears that there are no published reports on childhood slow transit constipation (STC) that have considered the state of the musculoskeletal components of the trunk in these children. The present study aimed to determine whether children with STC have different trunk musculoskeletal characteristics that might be related to their defecation difficulties, compared to controls. METHODS With the aid of computer-analyzed photographs and clinical testing, 41 children with STC and 41 age-matched controls were examined for Marfanoid features, sitting posture, spinal joint mobility and trunk muscle strength. The latter was assessed by measuring maximum voluntary abdominal bulging and retraction in sitting, and active trunk extension in prone-lying. Levels of general exercise and sedentary activities were evaluated by questionnaire. RESULTS STC subjects were more slumped in relaxed sitting (P < or = 0.001), less able to bulge (P < or = 0.03) and less able to actively extend the trunk (P = 0.02) compared to controls. All subjects sat more erect during abdominal bulging (P < or = 0.03). CONCLUSION The results show that STC children have reduced trunk control and posture, which indicates that clinicians should include training of trunk muscles and correction of sitting posture. There was no evidence that children with STC exercised less than the controls.

Abstract
OBJECTIVE We hypothesized that enemas and polyethylene glycol (PEG) would be equally effective in treating rectal fecal impaction (RFI) but enemas would be less well tolerated and colonic transit time (CTT) would improve during disimpaction. METHODS Children (4-16 years) with functional constipation and RFI participated. One week before disimpaction, a rectal examination was performed, symptoms of constipation were recorded, and the first CTT measurement was started. If RFI was determined, then patients were assigned randomly to receive enemas once daily or PEG (1.5 g/kg per day) for 6 consecutive days. During this period, the second CTT measurement was started and a child's behavior questionnaire was administered. Successful rectal disimpaction, defecation and fecal incontinence frequencies, occurrence of abdominal pain and watery stools, CTTs (before and after disimpaction), and behavior scores were assessed. RESULTS Ninety-five patients were eligible, of whom 90 participated (male, n = 60; mean age: 7.5 +/- 2.8 years). Forty-six patients received enemas and 44 PEG, with 5 dropouts in each group. Successful disimpaction was achieved with enemas (80%) and PEG (68%; P = .28). Fecal incontinence and watery stools were reported more frequently with PEG (P < .01), but defecation frequency (P = .64), abdominal pain (P = .33), and behavior scores were comparable between groups. CTT normalized equally (P = .85) in the 2 groups. CONCLUSION Enemas and PEG were equally effective in treating RFI in children. Compared with enemas, PEG caused more fecal incontinence, with comparable behavior scores. The treatments should be considered equally as first-line therapy for RFI.

Diagnostic accuracy of the Barr and Blethyn radiological scoring systems for childhood constipation assessed using colonic transit time as the gold standard. Pediatr Radiol 2009; 39:664-7. [PMID: 19277628 DOI: 10.1007/s00247-009-1205-x] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2008] [Revised: 01/15/2009] [Accepted: 01/21/2009] [Indexed: 01/16/2023]
Abstract
BACKGROUND Constipation is a common childhood symptom and abdominal radiography is advocated in diagnosis and management. OBJECTIVE To assess the reproducibility and diagnostic accuracy of the Barr and Blethyn systems for quantifying constipation on abdominal radiographs in children. MATERIALS AND METHODS Radiographs were scored by three observers of increasing radiological experience (student, junior doctor, consultant). Abdominal radiographs produced during measurement of colonic transit time (CTT) were classified as constipated or normal based on the value of the transit time, and were scored using both systems by observers blinded to the CTT. Abdominal radiographs obtained in children for reasons other than constipation were classed as normal and similarly scored. Reproducibility was measured using the kappa statistic. Diagnostic accuracy was measured using the area under the curve (AUC) for the receiver operator characteristic (ROC) curve. RESULTS Using either system, scores were higher for constipated children (P<0.01). The consultant produced higher scores than the other observers (P<0.01). Interobserver reproducibility was moderate with the best kappa value only 0.48. The best correlation between score and CTT was 0.51 (junior doctor scores). Diagnostic accuracy of the scores was only moderate, with the largest AUC for a ROC curve of 0.84 for the consultant using the Barr score. CONCLUSIONS Scoring of abdominal radiographs in the assessment of childhood constipation should be abandoned because it is dependent on the experience of the observer, is poorly reproducible, and does not accurately discriminate between constipated children and children without constipation.
