Abstract
BACKGROUND In 2018 diagnostic criteria for pediatric intestinal pseudo-obstruction (PIPO) were established. Neuromuscular dysfunction of the gastrointestinal tract is one of these, and often examined through antroduodenal manometry (ADM). There is little data on antroduodenal manometries in children. Our objectives were to retrospectively apply these criteria to children evaluated for suspected motility disorder, to reevaluate the ADM patterns and compare children who did and did not meet the PIPO criteria and also with healthy adults. METHODS Children with a suspected gastrointestinal motility disorder previously investigated with 24-h 8-lead ADM were reevaluated by applying the 2018 ESPGHAN/NASPGHAN PIPO diagnostic criteria and the 2018 ANMS-NASPGHAN guidelines. ADM findings were compared between children who retrospectively fulfilled a PIPO diagnosis, children who did not, and a control group of healthy adults. KEY RESULTS Of 34 children (age 7.9 (±5.1) years, 18 males), 12 retrospectively fulfilled the 2018 PIPO diagnostic criteria. Twenty-five children (10 in the PIPO group) had abnormal diagnostic findings on ADM, whereas 9 (2 in the PIPO group) had no such findings. A PIPO diagnosis implied a significantly higher degree of abnormal ADM patterns (2.33 vs. 1.23, p = 0.02). There were no major differences in quantitative ADM measurements between the groups except higher pressures in children. CONCLUSIONS AND INFERENCES Children who retrospectively fulfilled a PIPO diagnosis had a significantly higher abundance of abnormal ADM findings compared with symptomatic children without PIPO and healthy adults. Our data indicate a need for set criteria for evaluation of ADM in children with suspected PIPO.

Abstract
OBJECTIVES Antroduodenal manometry (ADM) measures antral and small bowel motility and is clinically used to evaluate upper gastrointestinal (UGI) symptoms. We aimed to evaluate its utility in guiding treatment, predicting response, and association with clinical findings. METHODS Retrospective review of 200 children undergoing ADM. ADM interpretation and parameters were compared to outcomes (response to first therapy after ADM and overall response), predominant symptom (group A, abdominal distention and/or vomiting and group B, abdominal pain and/or nausea), etiology (idiopathic or with known comorbidity), and ADM indication [suspected chronic intestinal pseudo-obstruction (CIPO) or unexplained UGI symptoms]. RESULTS We found an association between a normal intestinal phase III of the migrating motor complex (MMC) and idiopathic etiology, group B symptoms and unexplained UGI symptoms. No variable was associated with initial successful response. However, normal small bowel phase III of the MMC and idiopathic etiology were associated with overall successful response to treatment (including feeding tolerance and weaning of parenteral nutrition). No antral ADM parameter was associated with outcomes or other comparisons. The time to overall successful treatment response was significantly shorter in patients with a normal ADM and presence of a normal phase III of the MMC. CONCLUSIONS The presence of the phase III of the MMC was the single ADM parameter predictive of overall treatment response, also associated to group B symptoms and idiopathic etiology. Our findings suggest that small bowel ADM parameters are more useful to predict outcomes and ADM should be performed primarily in patients presenting with abdominal distention and/or vomiting and those being evaluated for CIPO.

Enhancing the utility of antroduodenal manometry in pediatric intestinal pseudo-obstruction. Neurogastroenterol Motil 2022; 34:e14259. [PMID: 34532939 DOI: 10.1111/nmo.14259] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 07/23/2021] [Accepted: 08/18/2021] [Indexed: 01/28/2023]
Abstract
BACKGROUND Antroduodenal manometry (ADM) and histopathology are currently employed to aid the diagnosis of pediatric intestinal pseudo-obstruction (PIPO). Limited data are available on the reliability of ADM analysis and its correlation with histopathology. We aimed to develop a protocol for enhanced analysis of ADM contractile patterns, including a scoring system, and explore whether this provided better correlation with histopathology. METHODS Children referred with suspected PIPO between April 2012-December 2019 who underwent both ADM and full-thickness biopsies were included. ADM tracings were analyzed using both standard (conventional ADM) and novel (enhanced ADM) motility parameters. A novel ADM score (GLASS score) was generated based on the enhanced ADM analysis. Conventional and enhanced ADM analyses were then correlated with histopathology. RESULTS Forty patients were included. Using conventional clinical criteria, 29 of these were diagnosed with PIPO and the other 11 with non-PIPO diagnoses. Twenty-three of the PIPO patients had abnormal histopathology: 6 myopathy, 4 neuropathy, 3 neuro-myopathy, and 10 non-specific changes. No agreement in diagnosis was found between conventional ADM analysis and histopathology (ϰ = 0.068; p = 0.197), whereas the latter significantly correlated with enhanced ADM analysis (ϰ = 0.191; p = 0.003). The enhanced ADM score was significantly higher in PIPO versus non-PIPO (16.0 vs. 8.0; p < 0.001). CONCLUSIONS As opposed to conventional analysis protocols, the newly developed enhanced ADM analysis and associated score is not only able to discriminate between PIPO and non-PIPO patients, but also between distinct histopathological pathologies. Further studies are required to assess the utility of enhanced ADM analysis in larger populations.

Abstract
OBJECTIVES Antroduodenal manometry (ADM) is used to evaluate antral and small intestinal motility, with the presence of phase III migrating motor complexes (MMCs) indicating an intact enteric neuromuscular system. The lack of evidence-based or consensus-driven established norms for MMC in fasting phase and after provocative testing marks a major limitation in the interpretation of ADM studies. We aimed to determine the characteristics of MMC in fasting and post-provocative phase in children. METHODS Data from subjects ages <20 years with ADM results evaluated at neuro-gastroenterology and Motility Disorders Center, Cincinnati Children's Hospital Medical Center from January 2018 to March 2019 were analyzed. RESULTS Forty-eight ADM tracings that did not demonstrate abnormal patterns were included; the mean age was 10.00 ± 5.72 years and 50% were male. Indications for ADM included: vomiting (27.1%), feeding intolerance (27.1%), abdominal pain (16.6%), nausea (14.6%), and abdominal distension (14.6%). Thirty-seven percent of subjects had enteral access for feeds. During fasting, one-third of all MMC originated in the antrum. Azithromycin-induced MMC occurred in 28% of subjects and two-thirds of these originated in the antrum with antral contractions of significantly higher frequency and amplitude compared to fasting. Octreotide significantly increased frequency, amplitude, and duration of MMC compared to fasting, with 76% originating in the antrum. Both azithromycin and octreotide induced more than one MMC in a third of subjects. CONCLUSIONS We describe the characteristics of antral and small intestinal motility during fasting and after provocative testing in children. These values will help standardize our interpretation of pediatric ADM studies.

Abstract
BACKGROUND We evaluated the changes in antroduodenal manometry (ADM) parameters and interpretation when the test is performed the day of catheter placement and the following day. METHODS Catheter was placed endoscopically under anesthesia and recorded on day 1 and repeated on day 2. Study parameters including antrum and small bowel motility index (MI) during fasting, meal, postprandial, erythromycin (EES), and octreotide (OCT) challenge phases, the presence of the phase III of the migrating motor complex (MMC), visual postprandial response, and study interpretation were compared between both days. KEY RESULTS Twenty patients were studied. Antrum and small bowel MI during fasting, postprandial, and EES challenge phases were significantly higher on day 2 than on day 1 (P < 0.05). The proportion of patients having a phase III of the MMC was significantly higher on day 2 compared to day 1 (65% vs 15%; P = 0.006). Study interpretation changed from day 1 to day 2. On day 1, 70% of the patients had a normal study and 30% had an abnormal study. On day 2, 67% of the patients with an abnormal study on day 1 changed to normal and 33% remained abnormal. All patients with a normal study on day 1 remained normal on day 2. CONCLUSIONS AND INFERENCES ADM parameters are affected the day of catheter placement. The MI and presence of the phase III of the MMC were significantly higher on day 2 compared to day 1. Overall, ADM study interpretation changed from day 1 to day 2 in 20% of the patients.

J Pediatr 2019; 205:138-144. [PMID: 30529135 DOI: 10.1016/j.jpeds.2018.09.048] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 08/22/2018] [Accepted: 09/14/2018] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To assess the utility of gastrointestinal (GI) diagnostic studies in the evaluation of patients with orthostatic intolerance. STUDY DESIGN Medical records of 103 consecutive children/young adults with orthostatic intolerance and gastrointestinal symptoms were reviewed. All patients had undergone antroduodenal manometry in conjunction with the tilt table test, autonomic testing, and upper gastrointestinal endoscopy (EGD). A gastric emptying study (GES) was performed in 81 patients. RESULTS The median age of the cohort was 17 years (IQR, 15-19) with a female predominance (females:males, 3:1). As expected, the tilt table test was abnormal in all patients. Antroduodenal manometry was abnormal in 83 of 103 patients (81%), showing neurogenic intestinal dysmotility in 50%, rumination in 20%, and visceral hyperalgesia in 10%. The GES results were abnormal in 23 of 81 patients (28.4%), mostly (21 of 23) with delayed GES. None of the tilt table test or autonomic results were predictive of abnormal antroduodenal manometry or GES. Analysis of EGD biopsy samples revealed nonspecific esophagitis and/or gastritis in 16 of 103 patients (15%). CONCLUSIONS Antroduodenal manometry with the tilt table test were the most insightful investigations in adolescents and young adults with orthostatic intolerance and gastrointestinal symptoms. GES and EGD provided limited information. Gastrointestinal symptoms were related more to functional rather than mucosal or organic etiologies, suggesting a limited role of endoscopy alone in evaluating patients with orthostatic intolerance presenting with gastrointestinal symptoms.

Abstract
Background/Aims High-resolution methods have advanced esophageal and anorectal manometry interpretation but are incompletely established for intestinal manometry. We characterized normal fasting duodeno-jejunal manometry parameters not measurable by standard techniques using clustered closely-spaced recordings. Methods Ten fasting recordings were performed in 8 healthy controls using catheters with 3–4 gastrointestinal manometry clusters with 1–2 cm channel spacing. Migrating motor complex phase III characteristics were quantified. Spatial-temporal contour plots measured propagation direction and velocity of individual contractions. Coupling was defined by pressure peak continuity within clusters. Results Twenty-three phase III complexes (11 antral, 12 intestinal origin) with 157 (95% CI, 104–211) minute periodicities, 6.99 (6.25–7.74) minute durations, 10.92 (10.68–11.16) cycle/minute frequencies, 73.6 (67.7–79.5) mmHg maximal amplitudes, and 4.20 (3.18–5.22) cm/minute propagation velocities were recorded. Coupling of individual contractions was 39.1% (32.1–46.1); 63.0% (54.4–71.6) of contractions were antegrade and 32.8% (24.1–41.5) were retrograde. Individual phase III contractions propagated > 35 fold faster (2.48 cm/sec; 95% CI, 2.25–2.71) than complexes themselves. Phase III complexes beyond the proximal jejunum were longer in duration (P = 0.025) and had poorer contractile coupling (P = 0.025) than proximal complexes. Coupling was greater with 1 cm channel spacing vs 2 cm (P < 0.001). Conclusions Intestinal manometry using clustered closely-spaced pressure ports characterizes novel antegrade and retrograde propagation and coupling properties which degrade in more distal jejunal segments. Coupling is greater with more closely-spaced recordings. Applying similar methods to dysmotility syndromes will define the relevance of these methods.

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
Chronic intestinal pseudo-obstruction (CIP) is defined by either continuous or intermittent symptoms of bowel obstruction in the absence of fixed lumen excluding lesion. CIP includes a heterogeneous group of disorders which result either from diseases affecting the enteric neurons and smooth muscle lining or those involving the autonomic innervation of the bowel. Symptoms associated with CIP are nonspecific, which can sometimes contribute to the delay in recognizing the condition and making the correct diagnosis. The diagnostic workup should include imaging and manometry studies and, occasionally, full-thickness bowel biopsies for histopathological examination may be required. Multidisciplinary team approach for the management of these patients is recommended, and the team members should include a gastroenterologist, surgeon, chronic pain specialist, clinical nutritionist, and a psychologist. The treatment goals should include optimizing the nutritional status and preventing or delaying the development of intestinal failure. The majority of the patients require enteral or parenteral nutrition support, and chronic pain is a common and distressing symptom. Small bowel transplantation may be required if patients develop liver complications due to parenteral nutrition, have difficult central line access, or have poor quality of life and worsening pain despite aggressive medical management.

Abstract
OBJECTIVES Gastrointestinal (GI) symptoms of nausea, vomiting, and abdominal pain are common in patients with orthostatic intolerance (OI), including neurally mediated hypotension (NMH) and postural orthostatic tachycardia syndrome (POTS). Autonomic dysregulation is considered the underlying pathophysiology behind the cardiovascular symptoms of POTS. Because the autonomic nervous system also regulates GI motility, we hypothesized that patients with POTS and GI symptoms will have evidence of autonomic dysmotility of the upper GI tract. METHODS Thirty-five subjects with OI and GI symptoms were studied. All the subjects had a 24-hour antroduodenal manometry (ADM) study, in conjunction with pharmacologic challenge and autonomic and tilt table testing (TTT). RESULTS The mean subject age was 16.2 ± 2.8 years (range 10-23.8 years), and male to female ratio was 10:25. TTT was abnormal in all the 35 subjects, whereas Valsalva testing was abnormal (+40 mmHG) in 21 of 34 (62%) subjects, and corrected QT interval was ≥0.44 seconds in 19 of 35 (54%) subjects. During TTT, GI symptoms were reproduced in 31 of 35 (89%) studies. ADM was found to be abnormal at baseline, before the TTT in 5 of 35 (14%) subjects, whereas it became abnormal in 23 of 34 (68%) subjects during TTT. In addition, the expected response to the pharmacologic challenge was limited. Overall, ADM was abnormal in 26 of 35 (74%) patients either at baseline or during TTT in these subjects with OI. CONCLUSIONS ADM is frequently abnormal in children with OI and GI symptoms. Upper GI motility studies should be a part of the comprehensive evaluation in this population.

Abstract
Interobserver variability affects investigations involving assessment of complex visual data, such as histopathology, radiology and motility. This study assessed interobserver variation for interpretation of antroduodenal manometry (ADM), as this has not been previously investigated. Thirty-five ADM recordings from children aged 0.3-18 years were independently evaluated by five experienced paediatric gastroenterologists who were blinded to cases' clinical histories. Intra-class correlation (ICC) was analysed for detection and measurement of phase three of the migrating motor complex (MMC) and Cohen's kappa statistic was calculated between observer pairs for detection of specific motility features and final diagnosis. Observers were unanimous on the differentiation of normal and abnormal motility in 63% of cases. There was excellent interobserver agreement for the number of phase three of the MMC in fasting (ICC = 0.82, P < 0.0001) and for measurements of phase three of the MMC (ICC = 0.9999, P < 0.0001). Detection of other normal and abnormal motility patterns varied more. Objective findings such as the presence of phase three of the MMC correlated more closely than findings that involved the integration of several variables, such as final diagnosis. However, these data overall indicate that agreement between expert observers for the distinction of normal and abnormal antroduodenal motility compares favourably with other standard medical assessments.

Abstract
Tests of gastric, small intestinal and colonic motor function provide relevant physiological information and are useful for diagnosing and guiding the management of dysmotilities. Intraluminal pressure measurements may include concurrent measurements of transit or intraluminal pH. A consensus statement was developed and based on reports in the literature, experience of the authors, and discussions conducted under the auspices of the American Neurogastroenterology and Motility Society in 2008. The article reviews the indications, methods, performance characteristics, and clinical utility of intraluminal measurements of pressure activity and tone in the stomach, small bowel and colon in humans. Gastric and small bowel motor function can be measured by intraluminal manometry, which may identify patterns suggestive of myopathy, neuropathy, or obstruction. Manometry may be most helpful when it is normal. Combined wireless pressure and pH capsules provide information on the amplitude of contractions as they traverse the stomach and small intestine. In the colon, manometry assesses colonic phasic pressure activity while a barostat assesses tone, compliance, and phasic pressure activity. The utility of colonic pressure measurements by a single sensor in wireless pressure/pH capsules is not established. In children with intractable constipation, colonic phasic pressure measurements can identify patterns suggestive of neuropathy and predict success of antegrade enemas via cecostomy. In adults, these assessments may be used to document severe motor dysfunction (colonic inertia) prior to colectomy. Thus, intraluminal pressure measurements may contribute to the management of patients with disorders of gastrointestinal and colonic motility.

Abstract
Over the past decades our knowledge of normal and abnormal gastrointestinal motility has increased tremendously. The availability of manometry to study bowel contraction patterns, laparoscopy to perform full thickness bowel biopsies for histological examination, have added to the investigative armamentarium and helped better diagnose motility disorders. However, the development of newer therapies for bowel motility disorders has been disappointingly slow. Newer modalities such as gastric and bowel pacing provides some hope for the future. In this article we have provided an overview of some of the common motility disorders in children and discussed their management.

Abstract
AIM To compare epigastric impedance versus scintigraphy in monitoring the gastric emptying of the same adapted milk formula in infants. METHODS Seven infants with clinical symptoms of gastric motility disease underwent scintigraphy with 99mTc sulphur colloid for the 90 min following the ingestion of the same adapted milk formula, in order to evaluate gastric emptying. A bio-impedance device, connected to a PC, was prepared for this purpose with four standard electrodes placed anteriorly on the upper part of the body. The obtained graphs were compared to those of the scintigraphic method. Statistical analysis was performed using Pearson correlation. The confidence limits were set at 95%. Parental consent was obtained before each analysis. RESULTS The gastric emptying patterns obtained with epigastric impedance were closely correlated to those shown by the scintigraphy (r = 0.86 +/- 0.08; p < 0.05). A significant correlation between the gastric emptying velocity measured by the two techniques was found (r = 0.94; p = 0.002). CONCLUSIONS Epigastric impedance in infants provided estimates of gastric emptying that were closely correlated with scintigraphy. However, the limits derived from the epigastric impedance suggest that, at the moment, the two methods should not be used interchangeably.

Abstract
BACKGROUND In chronically ill children who refuse to eat, surgery to correct anatomic problems and behavioral treatments to overcome oral aversion often succeed. A few patients fail with standard treatments. The aims of the study were to: 1) investigate motility and gastric sensory abnormalities and 2) describe treatment that was individualized based on pathophysiology in children who failed surgery and behavioral treatments. METHODS We studied 14 patients (age 1.5-6; mean 2.5; M/F: 7/7). All had a lifelong history of food aversion and retching or vomiting persisting after feeding therapy and fundoplication. All were fed through gastrostomy or gastro-jejunostomy tubes. We studied esophageal and antroduodenal manometry, and gastric volume threshold for retching. We identified when gastric antral contractions were associated with retching and pain. A multidisciplinary treatment program included a variable combination of continuous post-pyloric feedings, drugs to decrease visceral pain, drugs for motility disorders, and behavioral, cognitive, and family therapy. We interviewed parents 2-6 months following testing to evaluate symptoms, mode of feeding and emotional health. RESULTS We found a motility disorder alone in 2, decreased threshold for retching alone in 5 and both motility and sensory abnormalities in 7. After treatment, 6 of 14 (43%) began eating orally and 80% had improved emotional health. Retching decreased from 15 episodes per day to an average of 1.4 per day (p <0.01). CONCLUSIONS Upper gastrointestinal motor and/or sensory disorders contributed to reduced quality of life for a majority of children and families with persistent feeding problems. A multidisciplinary approach improved symptoms and problems in these children

Abstract
Our aim was to analyse the patterns of ileal contractions in children. We reviewed the charts of 23 children who had ileal manometry studies (16 males), mean age 7 years (range 2 months to 17 years). We positioned the manometry catheters with 4-8 recording sites, 5 or 15 cm apart, through ileostomies fashioned for clinically indicated reasons. We studied six additional children with persistent faecal soiling following endorectal pull through for Hirschsprung's disease; the catheters were positioned through the anus and colon into the ileum. We recorded phasic and tonic intermittent contractions in all the subjects, clustered contractions (rate 5-9 min-1, duration 20-120 s) in 19 subjects with ileostomies and four with endorectal pull throughs. In 13 children there were prolonged propagated contractions, > 60 mmHg in amplitude, > 15 s in duration, propagating at rates of 2-6 cm s-1 over at least 20 cm. The migrating motor complex was rare; in 55 h of fasting recording there were two phase III sequences. There are four distinctive features of ileal manometry recordings in children: random intermittent contractions, clustered contractions, prolonged propagated contractions and tonic contractions. The features of ileal motility differ from motility in the proximal small bowel.

Abstract
Pediatric condition falsification may masquerade as chronic and serious digestive disease, including chronic intestinal pseudo-obstruction. The purpose of this study was to define clinical criteria to discriminate between these two conditions. We compared medical records of 8 pediatric condition falsification victims to those of 14 children with chronic intestinal pseudo-obstruction. Clinical features suggesting pediatric condition falsification in toddlers presenting with chronic and severe digestive complaints included (a) daily abdominal pain, (b) illness involving three or more organ systems, (c) an accelerating disease trajectory, (d) a reported history of preterm birth, (e) absence of dilated bowel on x-ray, (f) normal antroduodenal manometry, and (g) no urinary neuromuscular disease. These results suggest that a diagnosis of pediatric condition falsification may be suspected in toddlers presenting with a phenotype for enteric neuromuscular disorders by features in the clinical history, symptoms, and signs.

Abstract
A variety of drugs are used in the neonatal nursery for the management of feeding intolerance, gastroesophageal reflux, and acid-related disease. Although the pharmacokinetics of some of these drugs have been described in infants and older children, further data are needed, particularly for preterm infants. No data are available characterizing the disposition of the proton pump inhibitors, which will likely be used in infants with refractory, acid-related disease. Further data are also needed to characterize fully the pharmacodynamics, or efficacy, of many of the commonly used drugs.

Abstract
OBJECTIVES To evaluate the clinical presentation and to assess the usefulness of antroduodenal manometry (ADM) and the results of multidisciplinary team management in 12 neurologically normal adolescents (9 girls) with rumination. STUDY DESIGN All patients had extensive investigations that ruled out other causes of their chronic symptoms. We performed ADM in all patients. A multidisciplinary approach was used for the nutritional and behavioral rehabilitation of these patients. RESULTS The median age at presentation was 14 years (range, 9-19 years), and the average duration of symptoms was 17 months. All patients complained of postprandial, effortless regurgitation, and the majority had weight loss and abdominal pain. Results of fasting ADM were normal in all. The postprandial ADM showed brief, simultaneous pressure increases at all recording sites, associated with regurgitation in 8 patients. No emesis was observed in the other 4 children during the study. Treatment included nutritional support in combination with antidepressants and anxiolytics (n = 6), cognitive therapy with biofeedback or relaxation techniques (n = 7), and pain management (n = 2). Resolution or improvement of symptoms was seen in 10 of the 12 patients, and successful transition to oral feedings was achieved in all during the follow-up period, which ranged from 5 to 36 months. CONCLUSIONS Rumination is a distinct functional gastrointestinal disorder of otherwise healthy children and adolescents, which can be diagnosed on the basis of clinical features. The ADM shows a characteristic pattern and rules out motility disorders that are often confused with rumination. A multidisciplinary team approach is associated with satisfactory recovery in most patients.
