Abstract
BACKGROUND There is wide variation in the clinical use of diagnostic tools for children with chronic constipation and functional/structural fecal incontinence (CCFSFI). Anorectal manometry (ARM) is a well-recognized technique to assess the function of the anorectum. PURPOSE Our aim was to perform an up-to-date review on ARM in pediatric patients with CCFSFI, with specific focus on the indication of use and protocol. Variation of its use in pediatrics will be explored. METHODS A systematic search was conducted for empirical studies utilizing ARM with a pediatric sample. A keyword search of literature published in English before July 2018 was conducted and updated to October 2019. Data on demographics, clinical information, study aims, ARM parameters and use of sedation/anesthesia were collected. KEY RESULTS A total of 227 studies were included in this systematic review. The age of study participants at the time of ARM ranged from birth to 18 years. ARM was most commonly used in patients with organic conditions (65%) compared to functional constipation (41%). In almost half [108/227 (48%)] of the studies, ARM was performed awake. The ARM parameters most frequently assessed were the rectoanal inhibitory reflex, which was evaluated in 198/227 studies (87%) and the anal resting pressure [166/227 studies (73%)]. CONCLUSIONS AND INFERENCES This systematic review has highlighted the vast variation of ARM use within pediatrics and the need to strive toward standardization and use of consensus guidelines. We anticipate this will further advance our understanding of the pathophysiological mechanisms involved in children with defecation disorders.

Evaluation of Fecal Incontinence in Pediatric Functional Constipation: Clinical Utility of Anorectal and Colon Manometry. J Pediatr Gastroenterol Nutr 2021; 72:361-365.

Abstract
OBJECTIVES The aim of the study is to evaluate the utility of motility studies in pediatric functional constipation with/without fecal incontinence. PATIENTS AND METHODS Patients with functional constipation and failure to conventional therapy undergoing colonic manometry (CM) and/or anorectal manometry (ARM) manometry were classified as functional constipation without fecal incontinence (FC) or with fecal incontinence (FCI). Clinical data, motility parameters, and treatment outcomes were compared. RESULTS A total of 280 were included, and all patients underwent CM (229 FC and 51 FCI) and 219 ARM. We found no difference in CM interpretation and presence of normal high amplitude propagating contractions (HAPCs) between groups; however, patients with FCI had higher frequency and presence of HAPCs and normal gastrocolonic meal response (GC). No CM parameter predicted outcomes. In FC, more patients with an abnormal CM responded to therapy compared to those with a normal study (79% vs 65% respectively, P = 0.04). FCI patients had lower median anal resting pressure compared to FC (49 vs 66 mmHg, respectively, P = 0.03); no other ARM parameter differentiated FC from FCI. We found no association between therapy response and ARM interpretation (P = 0.847) or any ARM parameter. A multivariate analysis found only male gender was associated with FCI (P < 0.001). CONCLUSIONS FCI patients have higher frequency of normal CM parameters compared to FC, but overall interpretation was no different. CM helped predict response to therapy in FC but not in FCI. ARM demonstrated no added benefit in the evaluation of functional constipation with/without soiling. Patients with both normal ARM and CM had a lower response to therapy than those with abnormal studies.

Simultaneous assessment of colon motility in children with functional constipation by cine-MRI and colonic manometry: a feasibility study. Eur Radiol Exp 2021; 5:8. [PMID: 33565002 PMCID: PMC7873179 DOI: 10.1186/s41747-021-00205-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Accepted: 01/19/2021] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Colonic manometry is the current reference standard for assessing colonic neuromuscular function in children with intractable functional constipation (FC). Recently, cine magnetic resonance imaging (cine-MRI) has been proposed as a non-invasive alternative. We compared colonic motility patterns on cine-MRI with those obtained by manometry in children, by stimulating high-amplitude propagating contractions (HAPCs) with bisacodyl under manometric control while simultaneously acquiring cine-MRI. METHODS After Institutional Review Board approval, adolescents with FC scheduled to undergo colonic manometry were included. A water-perfused 8-lumen catheter was used for colonic manometry recordings. After an intraluminal bisacodyl infusion, cine-MRI sequences of the descending colon were acquired for about 30 min simultaneously with colonic manometry. Manometry recordings were analysed for HAPCs. MRI images were processed with spatiotemporal motility MRI techniques. The anonymised motility results of both techniques were visually compared for the identification of HAPCs in the descending colon. RESULTS Data regarding six patients (three males) were analysed (median age 14 years, range 12-17). After bisacodyl infusion, three patients showed a total of eleven HAPCs with colonic manometry. Corresponding cine-MRI recorded high colonic activity during two of these HAPCs, minimal activity during seven HAPCs, while two HAPCs were not recorded. In two of three patients with absent HAPCs on manometry, colonic activity was recorded with cine-MRI. CONCLUSIONS Simultaneous acquisition of colonic cine-MRI and manometry in children with FC is feasible. Their motility results did not completely overlap in the identification of HAPCs. Research is needed to unravel the role of cine-MRI in this setting.

Abstract
Motility of the large bowel may be grossly subdivided in two types of contractile activity: low-amplitude single or cyclic propagated waves and high-amplitude propagated activity. The latter is mainly apt to shift relatively large amounts of colonic contents, and it is related to defecation. The main component of this propagated activity is represented by the radiologically identified mass movements that have a manometric equivalent known as high-amplitude propagated contractions (HAPC). The present article reviews origins and characterization of HAPC in the time course of colonic motility investigations, and correlates it with technological advancements in recent years, putting into perspective the future possible options to better detect and investigate these important physiological events.

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.

Abstract
The gastrocolic reflex is a response of the colon to the presence of food in the stomach. Our goal was to observe bowel movements in healthy infants and toddlers not yet toilet trained, in response to a meal. Stool behavior of 40 toddlers, aged 18-27 months, was monitored. We observed a bowel movement within the first hour after a meal in 75% of the children. This occurred 15, 30 or 60 minutes after a meal in, respectively, 25%, 48% and 66% of the observations. If we limit to the ones that actually defecated, 37% would defecate within 15 minutes and 72% within half an hour. Fifty-nine percent of all children defecated in the morning, 54% at noon and 28% in the evening. In conclusion, we believe the gastrocolic reflex can be used as a facilitating factor to help a child to defecate on the potty, 15-30 minutes after a meal. In 50% of the cases, a child will have a bowel movement on the potty and learn to defecate on it much easier.

Abstract
Paediatric functional abdominal pain disorders, currently referred to as disorders of gut-brain interaction, comprise irritable bowel syndrome, functional dyspepsia, abdominal migraine and functional abdominal pain not otherwise specified, as defined by the Rome IV diagnostic criteria. Functional abdominal pain disorders are common disorders with a prevalence of 3-16% depending on country, age and sex. A greater understanding of aetiopathogenesis and pathophysiology is emerging and includes intestinal components (inflammation, motility and the microbiota), central factors (psychological aspects, sensitization and/or differences in connectivity or activity of certain brain regions) as well as extrinsic factors (infections). In particular, the timing of disruption of the microbiota-gut-brain axis seems to be important. Diagnosis is challenging but is primarily based on clinical symptoms and exclusion of other organic causes, with an emphasis on avoiding unnecessary invasive diagnostic procedures. The available pharmacological interventions are limited in children and, therefore, management has focused on combined approaches, including mind-targeted interventions (hypnotherapy and cognitive behavioural therapy), diet (probiotics) and percutaneous electrical nerve field stimulation. The evidence for their clinical efficacy, although limited, is favourable, with positive impacts on symptoms and overall quality of life. The coming decades hold promise for improved understanding and management of these enigmatic disorders.

Abstract
BACKGROUND High-resolution anorectal manometry (HR-ARM) is expected to be better than conventional manometry. Our aim was to characterize HR-ARM pressures in children with functional constipation (FC), with or without fecal incontinence (FI). METHODS Children with diagnosis of FC, with or without FI, according to Rome-IV criteria, were enrolled. All patients underwent HR-ARM using 24-channel water-perfused catheter. RESULTS Twenty-nine consecutive children (M/F: 21/8; mean age ± SD: 9.5 ± 3.1 years; range 4-15), of whom 21 affected by FC without FI (mean age ± SD: 9.3 ± 3.23 years) and 8 affected by FC with FI (mean age ± SD: 10.2 ± 3.08 years), were enrolled. No significant differences were found regard to gender and age. The analysis of HR-ARM 3D plots demonstrated asymmetry of the anal canal, with higher pressures in distal halves. Comparing pressures between the two groups, we found lower values in FC with FI than in FC without FI group, with a statistically significance for maximum and mean resting pressures (P = .032 and P = .008, respectively). When evaluating our study population respect to asymptomatic children, we found lower resting pressures, lower maximum squeeze pressure, and higher rectoanal inhibitory reflex (RAIR) values. CONCLUSIONS Our data demonstrate that HR-ARM pressures at rest and during squeezing in FC with FI children are lower than FC without FI subjects, particularly in anteroposterior quadrants. Compared to children without lower gastrointestinal symptoms, children with FC with or without FI show lower pressures and higher values of RAIR.

Abstract
BACKGROUND Colonic manometry with intraluminal bisacodyl infusion can be used to assess colonic neuromuscular function in children with treatment-refractory constipation. If bisacodyl does not induce high-amplitude propagating contractions (HAPCs), this can be an indication for surgical intervention. A detailed characterization of the colonic response to intraluminal bisacodyl in children with constipation may help to inform clinical interpretation of colonic manometry studies. METHODS Studies were performed in five pediatric hospitals. Analysis included identification of HAPCs, reporting HAPCs characteristics, and an area under the curve (AUC) analysis. Comparisons were performed between hospitals, catheter type, placement techniques, and site of bisacodyl infusion. RESULTS One hundred and sixty-five children were included (median age 10, range 1-17 years; n = 96 girls). One thousand eight hundred and ninety-three HAPCs were identified in 154 children (12.3 ± 8.8 HAPCs per child, 0.32 ± 0.21 HAPCs per min; amplitude 113.6 ± 31.5 mm Hg; velocity 8.6 ± 3.8 mm/s, propagation length 368 ± 175 mm). The mean time to first HAPC following bisacodyl was 553 ± 669 s. Prior to the first HAPC, there was no change in AUC when comparing pre- vs post-bisacodyl (Z = -0.53, P = .60). The majority of HAPCs terminated in a synchronous pressurization in the rectosigmoid. Defecation was associated with HAPCs (χ2 (1)=7.04, P < .01). Site of bisacodyl administration, catheter type, and hospital location did not alter the response. CONCLUSIONS AND INFERENCES Intraluminal bisacodyl induced HAPCs in 93% of children with treatment-refractory constipation. The bisacodyl response is characterized by ≥1 HAPC within 12 minutes of infusion. The majority of HAPCs terminate in a synchronous pressurization in the rectosigmoid. Optimal clinical management based upon colonic manometry findings is yet to be determined.

Abstract
Motility of the gut is affected by the nervous system, the endocrine system, smooth muscle cells, interstitial cells of Cajal, secretory mucosal cells, the immune system, and gut flora. Abnormal gastrointestinal motility can generate nonspecific symptom complaints that are refractory to standard treatment approaches. It is important to exclude anatomical obstruction or other causes for patients' symptoms prior to proceeding with motility evaluation. Motility studies that help to evaluate children with suspected motility problems include combined multichannel intraluminal impedance (MII) and pH recording, esophageal manometry, gastric emptying scinitigraphy, antroduodenal manometry, colonic manometry, and anorectal manometry. Many pediatric gastrointestinal motility evaluations should be completed in a pediatric motility center where specialized training is completed by physicians in this field. Indications for pediatric gastrointestinal motility studies and how the procedures are performed are addressed in this paper.

Abstract
ObjectiveFunctional constipation is one of the most common problems in pediatric gastroenterology. The aim of the present study was to evaluate the effectiveness of daily anal stimulation in infants with intractable functional constipation (IFC). Our evaluation was based on clinical improvement and on changes in manometric parameters through time.MethodsInfants with IFC treated between January 2018 and December 2019 were included in this retrospective study. Treatment processing included daily anal stimulation for infants and psychological counseling for parents. All cases underwent a complete intervention program and were evaluated for improvement in symptoms and for changes in anorectal manometry within 1 year of follow-up.ResultsA total of 161 patients were included in this study. Positive response was achieved in all patients. Frequency of defecation, change in stool form and decrease in the defecatory pain were significantly relieved in all infants after intervention. On anorectal manometry, no significant difference was found in the peristaltic frequency of distal rectum before and after treatment. There was a significant increase in the mean amplitude of peristalsis and improvement in the rhythm after intervention. In the 1 year of follow-up, three patients had recurrence of constipation requiring colectomy.ConclusionIn terms of the high clinical efficacy and limited side effects, daily anal stimulation may be included in the initial part of an intervention program for IFC in infants.

Abstract
Defecatory disorders in children, including chronic constipation (CC) and fecal incontinence (FI), are common conditions worldwide and have a significant impact on children, their families, and the healthcare system. Anorectal manometry (ARM) and high-resolution anorectal manometry (HRAM) are relatively novel tools for the assessment of anal sphincter function and rectal sensation and have contributed significantly to improving the understanding of the anorectum as a functional unit. ARM has been recognized as the investigation of choice for adults with symptoms of defecation disorders, including fecal incontinence (FI), evacuation difficulties, and constipation. Although it is the gold standard tool in adults, it has yet to be formally accepted as a standardized diagnostic tool in the pediatric age, with limited knowledge regarding indications, protocol, and normal values. ARM/HRAM is slowly becoming recognized among pediatricians, but given that there are currently no agreed guidelines there is a risk that will lead to diversity in practice. The British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN)-Motility Working Group (MWG) therefore has taken the opportunity to provide guidance on the use of ARM/HRAM in children with CC and/or FI.

Abstract
BACKGROUND High-resolution colonic manometry gives an unprecedented window into motor patterns of the human colon. Our objective was to characterize motor activities throughout the entire colon that possessed persistent rhythmicity and spanning at least 5 cm. METHODS High-resolution colonic manometry using an 84-channel water-perfused catheter was performed in 19 healthy volunteers. Rhythmic activity was assessed during baseline, proximal balloon distention, meal, and bisacodyl administration. KEY RESULTS Throughout the entire colon, a cyclic motor pattern occurred either in isolation or following a high-amplitude propagating pressure wave (HAPW), consisting of clusters of pressure waves at a frequency centered on 11-13 cycles/min, unrelated to breathing. The cluster duration was 1-6 minutes; the pressure waves traveled for 8-27 cm, lasting 5-8 seconds. The clusters itself could be rhythmic at 0.5-2 cpm. The propagation direction of the individual pressure waves was mixed with >50% occurring simultaneous. This high-frequency cyclic motor pattern co-existed with the well-known low-frequency cyclic motor pattern centered on 3-4 cpm. In the rectum, the low-frequency cyclic motor pattern dominated, propagating predominantly in retrograde direction. Proximal balloon distention, a meal and bisacodyl administration induced HAPWs followed by cyclic motor patterns. CONCLUSIONS AND INFERENCES Within cyclic motor patterns, retrograde propagating, low-frequency pressure waves dominate in the rectum, likely keeping the rectum empty; and mixed propagation, high-frequency pressure waves dominate in the colon, likely promoting absorption and storage, hence contributing to continence. Propagation and frequency characteristics are likely determined by network properties of the interstitial cells of Cajal.

Abstract
Characterization of high-amplitude propagating pressure waves (HAPWs or HAPCs) plays a key role in diagnosis of colon dysmotility using any type of colonic manometry. With the introduction of high-resolution manometry, more insight is gained into this most prominent propulsive motor pattern. Here, we use a water-perfused catheter with 84 sensors with intervals between measuring points of 1 cm throughout the colon, for 6-8 h, in 19 healthy subjects. The catheter contained a balloon to evoke distention. We explored as stimuli a meal, balloon distention, oral prucalopride, and bisacodyl injection, with a goal to optimally evoke HAPWs. We developed a quantitative measure of HAPW activity, the "HAPW Index." Our protocol elicited 290 HAPWs. 21% of HAPWs were confined to the proximal colon with an average amplitude of 75.3 ± 3.3 mmHg and an average HAPW Index of 440 ± 58 mmHg·m·s. 29% of HAPWs started in the proximal colon and ended in the transverse or descending colon, with an average amplitude of 87.9 ± 3.1 mmHg and an average HAPW Index of 3,344 ± 356 mmHg·m·s. Forty-nine percent of HAPWs started and ended in the transverse or descending colon with an average amplitude of 109.3 ± 3.3 mmHg and an average HAPW Index of 2,071 ± 195 mmHg·m·s. HAPWs with and without simultaneous pressure waves (SPWs) initiated the colo-anal reflex, often abolishing 100% of anal sphincter pressure. Rectal bisacodyl and proximal balloon distention were the most optimal stimuli to evoke HAPWs. These measures now allow for a confident diagnosis of abnormal motility in patients with colonic motor dysfunction.NEW & NOTEWORTHY High-amplitude propagating pressure waves (HAPWs) were characterized using 84 sensors throughout the entire colon in healthy subjects, taking note of site of origin, site of termination, amplitude, and velocity, and to identify optimal stimuli to evoke HAPWs. Three categories of HAPWs were identified, including the associated colo-anal reflex. Proximal balloon distention and rectal bisacodyl were recognized as reliable stimuli for evoking HAPWs, and a HAPW Index was devised to quantify this essential colonic motor pattern.

Abstract
PURPOSE There is a lack of diagnostic credibility to direct focused management for children with chronic constipation (CC) and faecal incontinence (FI). The aim is to assess the impact of an innovative Children's Anorectal Physiology Service (CAPS) focusing on improving outcomes in children with CC/FI. METHODS Prospective data: demographics, bowel and quality of life (QoL)/risk of distress questionnaires. Diagnostics: awake high-resolution anorectal manometry (AHRAM), endoanal ultrasound and transit marker studies (TMS). RESULTS Total patients: 112; 66 males (59%); median 9 years (17 months to 16 years). Patient groups included: 89 (79%) had functional CC/FI; 9 (8%), Hirschsprung's disease; 12 (11%), anorectal malformations and 2 (2%), trauma. St Marks Incontinence score (SMIS) abnormal in 91 (81%) and Cleveland Constipation Score (CCS) in 101 (90%) patients. Anorectal manometry: 94 (84%) awake and 18 (17%) under anaesthesia. Play specialist input 37 (33%) patients. AHRAM abnormal 65 (58%): sphincter dysfunction 36 (32%) and altered rectal sensation: hyposensitive 22% (20/91); 21% (19/91) hypersensitive. TMS normal in 64 (57%), 17 (15%) slow transit and 27 (24%) rectal evacuatory disorder. Risk of distress in 38% and poor QoL in 55% patients which correlated with abnormal SMIS (p = 0.02). Patient/parent satisfaction improved significantly (p < 0.05). CONCLUSIONS Scientific investigations combined with multidisciplinary team improve patient satisfaction and reduces patient self-report illness severity. A complex problem requires a scientific solution.

Abstract
PURPOSE The Oral-anal Transit Test (OTT) is a simple method of obtaining information about colonic transit. We aim to assess the correlation of OTT with the neuromuscular integrity of the colon determined by colonic manometry (CM). METHODS All patients who had OTT followed by CM were evaluated. Less than 6 of 24 markers remaining on OTT was considered normal. CM was performed per previously published guidelines. A normal CM was defined as at least one High Amplitude Propagating Contraction progressing from the most proximal sensor through the sigmoid colon. RESULTS A total of 34 patients underwent both OTT and CM (44% male, age 4-18 years, mean 11.5 years, 97% functional constipation +/- soiling, Hirschsprung's Disease). Of normal and abnormal OTT patients, 85.7% (6/7) and 18.5% (5/27) respectively had normal CM. When all markers progressed to at least the sigmoid colon, this was 100% predictive against colonic inertia. Greater than 50% of patients with manometric isolated sigmoid dysfunction had markers proximal to the recto-sigmoid. CONCLUSION OTT and CM are both valuable studies that assess different aspects of colonic function. OTT can be used as a screening test to rule out colonic inertia. However, the most proximal extent of remaining markers does not predict the anatomical extent of the manometric abnormality, particularly in isolated sigmoid dysfunction.

Abstract
OBJECTIVES Colon manometry (CM) has emerged as a tool to evaluate children with defecation problems. Our aim was to evaluate the utility of CM in guiding therapy and predicting surgery in pediatric constipation. METHODS Retrospective review of children undergoing CM for 4 indications: constipation, fecal incontinence, postsurgical evaluation and chronic intestinal pseudo-obstruction. Variables included age, sex, follow-up, and CM parameters: gastrocolonic response (GC) and quality/quantity of high-amplitude propagating contractions (HAPCs). INTERVENTIONS medical, surgical or no intervention. OUTCOMES response to change of therapy guided by CM, response to first intervention guided by CM (CMI) and CM predicting surgery (CMS). Response to therapy was classified according to study indication. RESULTS Five hundred fifty-five studies (448 patients, 54.4% female; median age 8.9 years) were included, 24% of studies were normal. Change of therapy guided by CM was associated with a high response rate (P = 0.003). Overall response to stimulant laxatives was 48% and was not associated with CM findings. Surgical interventions had a higher response rate than medical or other interventions (P < 0.001). We found no association between the CM interpretation and CMI, but an abnormal CM was predictive of surgery (P < 0.01). GC and presence/number of HAPCs were not associated with CMI or CMS. We also found no association between HAPC quality and CMI but partially propagated HAPCs were predictive of surgery (P < 0.001). Logistic regression analysis showed no factors associated with CMI; however, longer follow up and partially propagated HAPCs were predictive of surgery. CONCLUSIONS CM is useful in pediatric defecation disorders, although not predictive of successful medical intervention, an abnormal CM is predictive of surgery. CM should be performed only after medical interventions have failed and surgery is contemplated.

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

Abstract
Functional constipation is common in children and adults worldwide. Functional constipation shows similarities in children and adults, but important differences also exist regarding epidemiology, symptomatology, pathophysiology, diagnostic workup and therapeutic management. In children, the approach focuses on the behavioural nature of the disorder and the initial therapeutic steps involve toilet training and laxatives. In adults, management focuses on excluding an underlying cause and differentiating between different subtypes of functional constipation - normal transit, slow transit or an evacuation disorder - which has important therapeutic consequences. Treatment of adult functional constipation involves lifestyle interventions, pelvic floor interventions (in the presence of a rectal evacuation disorder) and pharmacological therapy. When conventional treatments fail, children and adults are considered to have intractable functional constipation, a troublesome and distressing condition. Intractable constipation is managed with a stepwise approach and in rare cases requires surgical interventions such as antegrade continence enemas in children or colectomy procedures for adults. New drugs, including prokinetic and prosecretory agents, and surgical strategies, such as sacral nerve stimulation, have the potential to improve the management of children and adults with intractable functional constipation.

Abstract
Hirschsprung disease (HSCR) is conventionally defined as aganglionosis of the distal rectum and a variable length of proximal contiguous bowel with a transition zone of ganglionic, but neuroanatomically abnormal, bowel located immediately upstream. Recent improvement in our understanding of the pathology and genetics of HSCR and relevant animal models indicates highly variable expressivity. The spectrum of intestinal neuropathology includes patients with very short-segment aganglionosis, limited to the distal 1 to 2 cm of the rectum, and possibly patients with no true aganglionic segment, but nonphysiological transition zone pathology in their distal rectums. The presence or absence of submucosal ganglion cells in a rectal biopsy is not sufficient to exclude these patients, in whom submucosal nerve hypertrophy and/or abnormal cholinergic mucosal innervation may be the only diagnostic clues. In addition, diagnosis or exclusion of HSCR by rectal biopsy now relies in part on mucosal patterns of calretinin immunohistochemistry, with less emphasis on submucosal tissue adequacy and assessment of cholinergic innervation. These recent trends in the surgical pathology approach to rectal biopsies may miss patients at the phenotypically milder end of the malformation spectrum, with profound implications for subsequent management, prognosis, and genetic counseling.

Abstract
Diagnosis or exclusion of Hirschsprung disease (HSCR) is a frequent exercise in any pediatric hospital. Although HSCR may present at different ages and with varied clinical findings, the most common presentation is a neonate with severe constipation or signs of intestinal obstruction. A variety of diagnostic tests including contrast enema and anorectal manometry may be used as diagnostic screens, but diagnosis ultimately rests upon histopathological evaluation of a rectal biopsy. For the experienced pathologist, conventional hematoxylin-and-eosin-stained sections often suffice to exclude HSCR or establish the diagnosis. However, ancillary diagnostic tests such as acetylcholinesterase histochemistry or calretinin immunohistochemistry are complementary and extremely helpful in some cases. In this Perspectives article, we review the clinical and pathological features of HSCR, highlight those that are found in most patients, and discuss how to address particularly challenging aspects of the diagnostic workup.

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.

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

Abstract
PURPOSE Children failing medical management for severe constipation and/or fecal incontinence may undergo surgical intervention for antegrade enema administration. We present a modification of the laparoscopic-assisted percutaneous endoscopic cecostomy (LAPEC) procedure that allows primary placement of a skin-level device. METHODS A single-institution retrospective review was performed from 2009 to 2015. In the modified technique the colonoscope is advanced to the cecum, cecal suspension sutures are placed under laparoscopic visualization, and percutaneous needle puncture of the cecum is performed under direct laparoscopic and endoscopic visualization. A skin-level cecostomy tube is then placed over a guide wire. Patient characteristics and 30-day results were analyzed by Fisher's exact test. RESULTS Fifty-two patients underwent attempted LAPEC. Successful LAPEC using both laparoscopic and endoscopic guidance was achieved in 46 (88.5%). A MIC-KEY device was placed in 38. Corflo PEG tube placement was necessary in 14 due to high BMI (mean 28.4). Colonoscopy failed to reach the cecum in 6 and laparoscopy alone was utilized to achieve successful tube placement. Cecostomy site infections occurred in 3 (5.8%), only in those undergoing PEG placement using a pull technique (p < 0.05). CONCLUSION Primary placement of a skin-level device was successful in the majority of patients undergoing cecostomy tube placement for bowel management utilizing antegrade colonic enemas. This technique avoids a second anesthesia for tube conversion. Visualization via colonoscopy with the use of cecal suspension sutures is recommended. High BMI necessitates initial placement of a PEG tube and complications exclusively occurred in this group. TYPE OF STUDY Clinical. LEVEL OF EVIDENCE IV Case series study.

Abstract
Background and Aims High-resolution anorectal manometry (HRM) is associated with significant patient and parent anxiety, which can impact the success and efficiency of the procedure. The nature of HRM necessitates cooperation of an alert child. This study examined effects of psychoeducation intervention on decreasing procedural distress in both pediatric patients and their parents. Methods A prospective randomized study of children aged 3–12 years, undergoing HRM, was performed utilizing child-centric educational video. Patients received either psychological preparation intervention or treatment-as-usual. Distress was assessed through self-reported and parent-reported anxiety measures (STAIC-S; STAI-S), physiological arousal measurements, and an observational scale of procedural distress (PBCL). Results A total of 63 children, aged 3–12 yrs (6.7 ± 2.5), completed the study. Measures of observed and reported distress and anxiety (PBCL; STAIC-S) were significantly less in children receiving intervention. Parents of children in the intervention group also reported significantly less preprocedural anxiety (STAI-S). Effects on physiological arousal were mixed, with significant preprocedural decrease in systolic blood pressure but no difference in heart rate from baseline. Conclusions Preprocedural psychological preparation was effective in decreasing pediatric patient and parental self-reported anxiety associated with HRM. Intervention decreased physician time necessary to successfully complete the study and significantly decreased the number of times patients had to endure balloon inflation.

Abstract
Constipation is a common problem in children. Although most children respond to conventional treatment, symptoms persist in a minority. For children with refractory constipation, anorectal and colonic manometry testing can identify a rectal evacuation disorder or colonic motility disorder and guide subsequent management. Novel medications used in adults with constipation are beginning to be used in children, with promising results. Biofeedback therapy and anal sphincter botulinum toxin injection can be considered for children with a rectal evacuation disorder. Surgical management of constipation includes the use of antegrade continence enemas, sacral nerve stimulation, and colonic resection.

Abstract
BACKGROUND In recent years, high-resolution manometry has been used in an attempt to gain a greater insight into the physiology/pathophysiology of colonic contractile activity in healthy adults and patients with colonic motility disorders. New colonic motor patterns have been identified and characterized, however, the clinical significance of these findings remains undetermined. PURPOSE This review will assess the current literature on colonic high-resolution manometry and determine if this procedure has advanced our understanding of colonic motility. The limitations, future directions, and the potential of this technique to assess the effects of treatment upon colonic motor patterns will also be discussed.

Abstract
BACKGROUND Using water-perfused (WP) high-resolution manometry, we recently demonstrated that children with functional constipation (FC) lacked the postprandial increase in distal colonic cyclic motor patterns that was observed in healthy adults. Our aim was to determine if similar results could be detected using a solid-state (SS) manometry catheter. METHODS We performed a retrospective analysis of 19 children with FC (median age 11.1 years, 58% male) who underwent colonic manometry with a SS catheter (36 sensors, 3 cm apart). Data were compared with previously published data using a WP catheter (36 sensors, 1.5 cm apart) recorded from 18 children with FC (median age 15 years; 28% male). KEY RESULTS The cyclic motor patterns recorded by the SS catheter did not differ from those previously recorded by the WP catheter. There was no detected increase in this activity in response to the meal in either group. Long-single motor patterns were recorded in most patients (n = 16, 84%) with the SS catheter. The number of these events did not differ from the WP recordings. In the SS data, HAPCs were observed in 4 children prior to the meal, in 5 after the meal. This did not differ significantly from the WP data. CONCLUSIONS & INFERENCES These data recorded by SS manometry did not differ from WP manometry data. Regardless of the catheter used, both studies revealed an abnormal colonic response to a meal, indicating a pathology which is not related to the catheter used to record these data.

Abstract
Constipation is one of the most common gastrointestinal symptoms in children. With a median reported prevalence of 12%, it accounts for about 25% of all pediatric gastroenterology consultations. The majority of children experiences functional constipation and do not usually require any diagnostic testing. For those children not responding to conventional medical treatment or in the presence of a more significant clinical picture, however, an accurate instrumental assessment is usually recommended to evaluate either the underlying pathophysiologic mechanisms or a possible organic etiology. The present review analyzes the possible diagnostic investigations for severely constipated children, focusing on their actual indications and their utility in clinical practice. During the last decade, there has been a remarkable increase in our knowledge of normal and abnormal colonic and anorectal motility in children, and a number of different techniques to measure transit and motility have been developed and are discussed in this narrative review.

Abstract
BACKGROUND Upper gastrointestinal symptoms in children are common and motility disorders are considered in the differential diagnosis. High resolution esophageal manometry (HRM) has revolutionized the study of esophageal physiology, and the addition of impedance has provided new insights into esophageal function. Antroduodenal motility has provided insight into gastric and small bowel function. PURPOSE This review highlights some of the recent advances in pediatric esophageal and antroduodenal motility testing including indications, preparation, performance, and interpretation of the tests. This update is the second part of a two part series on manometry studies in children (first part was on anorectal and colonic manometry [Neurogastroenterol Motil. 2016;29:e12944]), and has been endorsed by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and the American Neurogastroenterology and Motility Society (ANMS).

Abstract
BACKGROUND Colonic dilation is common in children with intractable functional constipation (FC). Our aim was to describe the association between segmental colonic dilation and colonic dysmotility in children with FC. METHODS We performed a retrospective study on 30 children with intractable FC (according to the Rome III criteria) who had undergone colonic manometry and contrast enema within a 12-month time period. Colonic diameter was measured at 5 cm intervals from the anal verge up to the splenic flexure. Moreover, the distance between the lateral margins of the pedicles of vertebra L2 was measured to provide a ratio (colonic diameter or length/distance between the lateral margins; "standardized colon size" [SCS]). All manometry recordings were visually inspected for the presence of high-amplitude propagating contractions (HAPCs); a parameter for colonic motility integrity. The intracolonic location of the manometry catheter sensors was assessed using an abdominal X-ray. KEY RESULTS Colonic segments with HAPCs had a significantly smaller median diameter than colonic segments without HAPCs (4.08 cm vs 5.48 cm, P<.001; SCS 1.14 vs 1.66, P=.001). Children with prematurely terminating HAPCs had significantly larger SCS ratios for colonic diameter than children with fully propagating HAPCs (P=.008). SCS ratios for the length of the rectosigmoid and the descending colon and the SCS ratio for sigmoid colon diameter were significantly larger in children with FC compared to a previously described normative population (P<.0001, P<.0001 and P=.0007 respectively). CONCLUSIONS & INFERENCES Segmental colonic dilation was associated with prematurely terminating HAPCs and may be a useful indicator of colonic dysmotility.

Abstract
BACKGROUND We evaluated the change in colon manometry (CM) parameters and interpretation comparing results when the study is performed the same day after the motility catheter is placed under anesthesia or the following day. METHODS CM catheter was placed with colonoscopy under anesthesia and recorded on day 1 and repeated on day 2. Study parameters including motility index during fasting, post-prandial and post-Bisacodyl challenge phase; gastrocolonic response; number, presence and propagation of high amplitude propagating contractions (HAPCs); and, study interpretation were compared between both the days. KEY RESULTS Motility index (fasting, post-Bisacodyl phase, P<.05), HAPC number (10.1 vs 6.6, P=.01) and the proportion of patients having HAPCs (92% vs 70%, P=.002) was significantly higher on day 2 vs day 1. HAPC propagation improved on day 2 vs day 1 (fully propagated, 49% vs 37%; partially propagated, 43% vs 33%; absent 8% vs 30%). Study interpretation changed from day 1 to day 2. On day 1, 37% had a normal study and 63% had an abnormal study. On day 2, all patients with a normal study on day 1 remained normal, and patients with an abnormal study on day 1, 53% remained abnormal and 47% had a normal study. CONCLUSIONS & INFERENCES CM parameters are affected the day the catheter is placed with colonoscopy under anesthesia. The number, presence, and propagation of HAPCs were significantly higher/improved on day 2 compared to day 1. Overall, CM interpretation changed from abnormal to normal from day 1 to day 2 in 47% of the patients.

Abstract
Gastrointestinal motility disorders in the pediatric population are common and can range from benign processes to more serious disorders. Performing and interpreting motility evaluations in children present unique challenges. There are primary motility disorders but abnormal motility may be secondary due to other disease processes. Diagnostic studies include radiographic scintigraphic and manometry studies. Although recent advances in the genetics, biology, and technical aspects are having an important impact and have allowed for a better understanding of the pathophysiology and therapy for gastrointestinal motility disorders in children, further research is needed to be done to have better understanding of the pathophysiology and for better therapies.

Abstract
This review intends to update what is known about and what is still a challenge in functional constipation (FC) in children regarding epidemiology, pathophysiology, diagnosis, and management. Although FC is a common childhood problem, its global burden remains unknown as data from parts of the world are missing. Another problem is that there is a large variation in prevalence due to differences in study methods and defining age groups. The pathophysiology of FC remains unclear to date but is probably multifactorial. Withholding behavior is likely to be the most important factor in toddlers and young children. Genetics may also play a role since many patients have positive family history, but mutations in genes associated with FC have not been found. Over the past years, different diagnostic criteria for FC in infants and children have been proposed. This year, Rome IV criteria have been released. Compared to Rome III, it eliminates two diagnostic criteria in children under the age of 4 who still wear diapers. Physical examination and taking a thorough medical history are recommended, but other investigations such as abdominal radiography, transabdominal recto-ultrasonography, colonic transit time, rectal biopsies, and colon manometry are not routinely recommended. Regarding treatment, guidelines recommend disimpaction and maintenance therapy with polyethylene glycol (PEG) with or without electrolytes. But experience shows that acceptability, adherence, and tolerance to PEG are still a challenge. Counseling of parents and children about causes of FC is often neglected. Recent studies suggest that behavior therapy added to laxative therapy improves the relief of symptoms. Further homogeneous studies, better-defined outcomes, and studies conducted in primary care are needed.
