Abstract
Anorectal manometry is one of the motility tests in children performed by pediatric gastroenterologist. It evaluates the motility function of anorectal tract. It is helpful for diagnosing children with constipation, rectal hypersensitivity, fecal incontinence, Hirschsprung disease, anal achalasia, and anorectal malformations. The most common indication to perform anorectal manometry is to diagnose Hirschsprung disease. It is a safe procedure. This paper discusses recent advances and reviews on anorectal motility disorders in children.

Saudi J Gastroenterol 2023; 29:365-370. [PMID: 37282445 PMCID: PMC10754377 DOI: 10.4103/sjg.sjg_67_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 03/21/2023] [Accepted: 04/10/2023] [Indexed: 06/08/2023] Open
Abstract
Background Endoscopic submucosal dissection (ESD) of rectal tumors involving the dentate line (RT-DL) is challenging because of the anatomical features of the anal canal. This study aimed to identify optimal techniques and sedation and to determine the clinical outcomes of ESD for RT-DL. Methods We retrospectively collected medical records and endoscopic results of patients who underwent ESD for rectal tumors between January 2012 and April 2021. Patients were divided into RT-DL and rectal tumors not involving the dentate line (RT-NDL) groups, as per involvement of the dentate line. The treatment results and clinical outcomes of the two groups were evaluated and analyzed. Additionally, subgroup analysis was performed in the RT-DL group for the sedation method involved. Results In total, 225 patients were enrolled and 22 were assigned to the RT-DL group. The complete resection rate (90.9% vs. 95.6%, P =0.336), delayed bleeding (13.6% vs. 5.9%, P =0.084), perforation (0% vs. 3.9%, P = 0.343), hospital stays (4.55 vs. 4.48 days, P = 0.869), and recurrence (0% vs. 0.5%) showed no significant group differences. However, in RT-DL group, the procedure time (78.32 vs. 51.10 min, P = 0.002) was longer and there was more perianal pain (22.7% vs. 0%, P = 0.001). The subgroup analysis revealed that deep sedation using propofol reduced perianal pain during the procedure (0/14 vs. 5/8, P = 0.002). Conclusions ESD of RT-DL is a safe and effective treatment despite the challenges of requiring a high level of technique and longer procedure time. In particular, ESD under deep sedation should be considered in patients with RT-DL to control perianal pain.

Accuracy of Anorectal Manometry to Detect the Rectoanal Inhibitory Reflex in Children: Awake Versus Under General Anesthesia. J Pediatr Gastroenterol Nutr 2023; 76:731-736. [PMID: 37040075 PMCID: PMC10171289 DOI: 10.1097/mpg.0000000000003779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Accepted: 01/30/2023] [Indexed: 04/12/2023]
Abstract
OBJECTIVES Our objective was to investigate if there is a difference in the detection of the rectoanal inhibitory reflex (RAIR) when an anorectal manometry (ARM) is performed awake or under general anesthesia. METHODS A retrospective review of ARM studies was performed to identify children who had undergone ARMs both while awake and under general anesthesia. We compared ARM outcomes including the detection of the RAIR and anal canal resting pressure. RESULTS Thirty-four children had received ARMs both while awake and under general anesthesia (53% female, median age at first ARM 7.5 years [range 3-18 years]). In 9 of 34 (26%) children the RAIR was solely identified during ARM under general anesthesia and not during ARM while awake. In 6 of 9 (66%) this was unrelated to the balloon volumes used during balloon inflations. In 4 of 34 (12%) children, assessment of the RAIR was inconclusive during ARM under general anesthesia due to too low, or loss of anal canal pressure. In 2 of those children, ARMs while awake showed presence of a RAIR. Anal canal resting pressures were higher during ARM while awake versus ARM under general anesthesia (median 70 [interquartile range, IQR 59-85] vs 46 mmHg [IQR 36-65] respectively, P < 0.001). CONCLUSIONS General anesthesia may affect the detection of a RAIR in 2 ways. On the one hand, it may facilitate better visualization in children in whom a RAIR could not be visualized while awake. On the other hand, it may cause a loss of anal canal pressure resulting in an inconclusive test result.

Abstract
OBJECTIVES To identify variables predicting interfractional anatomical variations measured with cone-beam CT (CBCT) throughout abdominal paediatric radiotherapy, and to assess the potential of surface-guided radiotherapy (SGRT) to monitor these changes. METHODS Metrics of variation in gastrointestinal (GI) gas volume and separation of the body contour and abdominal wall were calculated from 21 planning CTs and 77 weekly CBCTs for 21 abdominal neuroblastoma patients (median 4 years, range: 2 - 19 years). Age, sex, feeding tubes, and general anaesthesia (GA) were explored as predictive variables for anatomical variation. Furthermore, GI gas variation was correlated with changes in body and abdominal wall separation, as well as simulated SGRT metrics of translational and rotational corrections between CT/CBCT. RESULTS GI gas volumes varied 74 ± 54 ml across all scans, while body and abdominal wall separation varied 2.0 ± 0.7 mm and 4.1 ± 1.5 mm from planning, respectively. Patients < 3.5 years (p = 0.04) and treated under GA (p < 0.01) experienced greater GI gas variation; GA was the strongest predictor in multivariate analysis (p < 0.01). Absence of feeding tubes was linked to greater body contour variation (p = 0.03). GI gas variation correlated with body (R = 0.53) and abdominal wall (R = 0.63) changes. The strongest correlations with SGRT metrics were found for anterior-posterior translation (R = 0.65) and rotation of the left-right axis (R = -0.36). CONCLUSIONS Young age, GA, and absence of feeding tubes were linked to stronger interfractional anatomical variation and are likely indicative of patients benefiting from adaptive/robust planning pathways. Our data suggest a role for SGRT to inform the need for CBCT at each treatment fraction in this patient group. ADVANCES IN KNOWLEDGE This is the first study to suggest the potential role of SGRT for the management of internal interfractional anatomical variation in paediatric abdominal radiotherapy.

Abstract
Computed tomography (CT) is used in veterinary medicine for the diagnosis of bones and soft tissue diseases in various species. In addition, CT has recently been used to diagnose aquatic animals, including Selachimorpha, which are difficult to diagnose out of water. However, because Selachimorpha do not have adipose tissue in the coelomic cavity, the coelomic organs cannot be fully identified using non-contrast CT (NCCT). The aim of this study is to present the anatomical features of the cadaver, NCCT, and contrast-enhanced CT (CECT) as well as the change in CT values of the coelomic organs and musculature of the brownbanded bamboo shark. NCCT scans were performed under anaesthesia in one male and one female shark. CECT was performed 30 min after iopamidol was administered intravenously. The sharks were euthanized, frozen at -20°C, and sliced in the same position in which they were scanned. Using electric band saw, 10-mm transversal sections were obtained. The anatomical structures of both males and females were identified by transversal sections, and CT images homologous to transversal sections were then selected. Sagittal and coronal CECT images were also obtained to facilitate understanding of the location and size of coelomic organs. Although bone structure and air in organs could be sufficiently discriminated on NCCT image, the coelomic organs were almost indistinguishable. On the other hand, CECT images obtained sufficient contrast to identify most coelomic organs in addition to bone and air. The results provide an atlas of a cross-sectional anatomy and CECT images, which is useful information for the medical diagnosis of coelomic organs in live Selachimorpha.

Abstract
BACKGROUND Insufflation of the colon allows for adequate visualization of the mucosal tissue and advancement of the endoscope during colonoscopy. Most colonoscopies are performed with sedation to mitigate discomfort and enhance the colonoscopy experience for both the patient and the endoscopist. AIM We aimed to evaluate factors associated with difficulty maintaining insufflation. METHODS A cross-sectional study of individuals undergoing colonoscopy at the Oklahoma City Veterans Affairs Medical Center was performed. Experiencing difficulty maintaining air insufflation during colonoscopy was assessed with a questionnaire completed by the performing endoscopist at the end of procedure. Information regarding procedure times, sedation used, demographics, comorbidities, surgical history, and medications used was extracted from the medical record. A multivariate regression analysis was performed to identify factors associated with difficulty maintaining air insufflation. A P value < 0.05 was considered significant. RESULTS 996 Patients were included for the analysis. Difficulty with insufflation was reported in 240 (24%) colonoscopies; mean age of 63.8 ± 10.4 years old and 13% were female. Fellow trainees were involved in 669 (67%) colonoscopies. Older age (OR 1.02, P 0.03, CI [1.00-1.04]), diabetes (OR 1.5, 95% CI [1.03, 2.05]), fellow's involvement (OR 2.6. (95% CI [1.68, 4.09]), total procedure time (OR 1.02, 95% CI [1.00, 1.03]), mean number of adenomas (OR 1.05, 95% CI [1.00, 1.09]), and MAC use (OR 2.6, 95% CI [1.80, 3.85]) were independent predictors for difficulty in maintaining air insufflation. CONCLUSION Our findings suggest that endoscopists should be cognizant of colon insufflation issues in older, diabetic patients undergoing colonoscopies under deep sedation, particularly if prolonged procedure is anticipated or encountered.

Abstract
Background/Aims To assess the effectiveness and feasibility of a brief session of hypnosis to reduce distress in children with functional constipation undergoing anorectal manometry (ARM). Methods A partially-blinded randomized controlled pilot trial was conducted in children 4-18 years old scheduled for ARM. Children were randomized to receive a brief session of hypnosis prior to ARM or standard care. Non-blinded and blinded observers rated the child's level of distress using the Observation Scale of Behavioral Distress and a 4-point-Likert scale, respectively. Differences between groups were analyzed using Fisher's exact test or Mann-Whitney U test as appropriate. Results Data from 32 children (15 hypnosis and 17 standard care) were analyzed. Prior to insertion of the catheter, the observed mean levels of distress were lower in the hypnosis group according to both the non-blinded observer (median 0.0 [interquartile range {IQR} 0.0-0.3] vs 1.4 [IQR 0.3-2.4]; P = 0.009) and the blinded observer (median 0.0 [IQR 0.0-0.0] vs 0.5 [IQR 0.0-1.0]; P = 0.044). During ARM, observed and reported levels of distress did not differ significantly. In the hypnosis group, 92.9% of parents and children reported that hypnosis helped the child to relax. There were no significant differences in resting pressure, squeeze pressure, or duration of the procedure between both groups. Conclusion A brief session of hypnosis for children before ARM is an easily incorporable intervention that lowers distress levels prior to the procedure and is positively perceived by children and parents.

Abstract
Anorectal disorders are common in children. They are related to structural and/or functional abnormalities of the anorectum or pelvic floor with a variety of symptoms. Therefore, diagnostic tests to evaluate anorectal function can help to better understand the underlying pathophysiology and aetiology as well as facilitate patient management. During the past decades, substantial efforts have been made to improve anorectal function testing; however, more advanced investigations might lead to difficulties in interpretation. Additionally, a great diversity of equipment and protocols are used among centres, which may lead to heterogeneous interpretation of results. More studies to standardize methods of testing and validate reference values are strongly recommended in children. This review updates on the current indications and the protocol of anorectal manometry.

Abstract
The aim of this study was to evaluate regeneration of a chronic large anal sphincter defect in a pig model after treatment with a plasmid encoding Stromal Cell Derived Factor-1(SDF-1). METHODS Under ethics approved protocol 19 age/weight matched Sinclair mini-pigs were subjected to excision of the posterior 50% of anal sphincter muscle and left to recover for 6 weeks. They were randomly allocated to receive either saline treatment (Saline 1 ml, n = 5), 1 injection of SDF-1 plasmid 2 mg/ml (1 SDF-1, n = 9) or 2 injections of SDF-1, 2 mg/ml each at 2 weeks intervals (2 SDF-1, n = 5). Euthanasia occurred 8 weeks after the last treatment. In vivo outcomes included anal resting pressures done under anesthesia pre-injury, pre-injection and before euthanasia (8 weeks after treatment). Anal ultrasound was done pre injury and pre-euthanasia. Tissues were saved for histology and analyzed quantitatively. Two way ANOVA followed by Holm-Sidak test and one way ANOVA followed by the Tukey test were used for data analysis, p < 0.05 was regarded as significant. RESULTS Posterior anal pressures at the 3 time points were not significantly different in the saline group. In contrast, post-treatment pressures in the 1 SDF-1 group pressures were significantly higher than both pre-injury (p = 0.001) and pre-treatment time points (p = 0.003). At the post-treatment time point, both 1 SDF-1 (p = 0.01) and 2 SDF-1 (p = 0.01) groups had significantly higher mean pressures compared to the saline group. Histology showed distortion of normal anatomy with patchy regeneration in the control group while muscle was more organized in both treatment groups. CONCLUSIONS Eight weeks after a single or two doses of SDF-1injected into a chronic anal sphincter injury improved resting anal pressures and regenerated muscle in the entire defect. SDF-1 plasmid is effective in treating chronic defects of the anal sphincter in a large animal and could be clinically translated.

Abstract
OBJECTIVES To study changes in intra-anal pressure (IAP) and characteristics of the rectoanal inhibitory reflex (RAIR) during anorectal manometry (ARM) in patients undergoing anesthesia induction with propofol. METHODS Prospective study in which ARM was performed at baseline while patients were awake and repeated after propofol-induced anesthesia. We studied IAP and the presence and characteristics of the RAIR before and after propofol. RESULTS A total of 27 patients were included (63% male; 9.2 years). Three patients had obstructive symptoms after Hirschsprung disease repair (HSCR), and 24 had intractable constipation. At baseline, the RAIR was present on 21 of 27 patients and absent on 6 of 27. Of the six patients with an absent RAIR, it remained absent in four of six (three known HSCR, and one new diagnosis of IAS achalasia), and two of six had a normal RAIR during propofol. Therefore, RAIR was present in all patients with constipation. The mean resting IAP was significantly lower after propofol. The percentage of IAS relaxation after lower balloon volume inflations was significantly higher during propofol (P < 0.05). No difference was observed over the latency time or the total relaxation time after propofol. CONCLUSIONS Propofol can be used to assess the presence of the RAIR during ARM in children who are uncooperative and undergoing other procedures under anesthesia. On the other hand, propofol significantly reduces the resting IAP and increases the percentage of internal anal sphincter relaxation after balloon distention. These findings may impact the interpretation to decide if an intervention is needed, or if there is a possible spinal neuropathy.

Abstract
Introduction and objectives: Anorectal manometry is a test that evaluates the function of the rectum,but also the anus. It is useful for the diagnosis of several conditions like fecal incontinence and constipation.In children these tests are being increasingly used for all ages.The aim of this study was to determine the benefit of anorectal manometry in children and to report our experience.
Material and Methods:Over a period of four years, 273children that underwent anorectal manometry were included in the study,their data and tests results were analyzed.
Results:Out of 273 patients included,68,5% were boys and 31,5% were girls.The mean age was 9 years.154patients(51,6%) had Fecal incontinence(Group1),75children(27,5%) had chronic constipation(Group2),and both of them(Group3) were reported in 37children(13,6%).An awake manometry was performed in 248children(91%) however this test under sedation allowed us the exclusion of Hirschsprung’s disease in 21children(84%).In group1, 25%patients had bad anal contraction.In groupe3, 21,6%children had bad anal contraction.The statistical analysis showed a significant difference in age(p=0.022) and resting pressure(p=0.050) between the three groups.Children with fecal incontinence had a higher rate of dyssynergy,80.2% and 83.8% in groups 1 and 3 respectively compared to 60.4% in patients with chronic constipation(p=0,852)
Conclusion:The gold standard for the exploration of children’s terminal constipation and encopresis is the anorectal manometry.It is an important tool to establish diagnosis.In our study, this test allow the exclusion of Hirschsprung’s disease in infants with constipation, in other hand we found a higher rate of dyssynergy in children with fecal incontinence(80%) which had allow us to propose a biofeedback therapy.

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
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
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
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 Over the last few years, the study of the colon and anorectal function has experienced great technical advances that have facilitated the performance of the tests and have allowed a more detailed characterization of reflexes and motor patterns. As a result, we have achieved a much better understanding of the pathophysiology of children with defecation problems. Anorectal and colonic manometry are now commonly used in all major pediatric referral centers as diagnostic tools and to guide the management of children with intractable constipation and fecal incontinence, particularly when a surgical intervention is being considered. PURPOSE This review highlights some of the recent advances in pediatric colon and anorectal motility testing including indications and preparation for the studies, and how to perform and interpret the tests. This update has been endorsed by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN).

Abstract
INTRODUCTION Anorectal manometry (ARCM) provides valuable information in children with chronic constipation and fecal incontinence but may not be tolerated in the awake child. This study aimed to evaluate the effect of ketamine anesthesia on the assessment of anorectal function by manometry and to evaluate defecation dynamics and anal sphincter resting pressure in the context of pathophysiology of chronic functional (idiopathic) constipation and soiling in children. METHODS This was a prospective study of children who were investigated for symptoms of chronic constipation and soiling between April 2001 and April 2004. We studied 52 consecutive children who had awake ARCM, biofeedback training and endosonography (awake group) and 64 children who had ketamine anesthesia for ARCM and endosonography (ketamine group). We age matched 31 children who had awake anorectal studies with 27 who had ketamine anesthesia. RESULTS The children in awake and ketamine groups were comparable for age, duration of bowel symptoms and duration of laxative treatments. ARCM profile was comparable between the awake and the ketamine groups with regard to anal sphincter resting pressure, rectal capacity, amplitude of rectal contractions, frequency of rectal and IAS contractions and functional length of anal canal. Of 52 children who had awake ARCM, dyssynergia of the EAS muscles was observed in 22 (42%) and median squeeze pressure was 87mm Hg (range 25-134). The anal sphincter resting pressure was non-obstructive and comparable to healthy normal children. Rectoanal inhibitory reflex was seen in all children excluding diagnosis of Hirschsprung disease. CONCLUSIONS Ketamine anesthesia does not affect quantitative or qualitative measurements of autonomic anorectal function and can be used reliably in children who will not tolerate the manometry while awake. Paradoxical contraction of the EAS can only be evaluated in the awake children and should be investigated further as the underlying cause of obstructive defecation in patients with chronic functional constipation and soiling.
