Increased Grades of Rectal Intussusception: Role of Decline in Pelvic Floor Integrity and Association With Dyssynergic Defecation. Am J Gastroenterol 2024; 119:946-956. [PMID: 37975595 DOI: 10.14309/ajg.0000000000002605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 11/14/2023] [Indexed: 11/19/2023]
Abstract
INTRODUCTION The natural history of rectal intussusception (RI) is poorly understood. We hypothesized that decline in pelvic floor integrity and function leads to increasing RI grades. METHODS Retrospective analysis of a registry of patients with defecatory disorders with high-resolution anorectal manometry and magnetic resonance defecography was performed. Association of risk factors on increasing RI grades was assessed using logistic regression. RESULTS Analysis included a total of 238 women: 90 had no RI, 43 Oxford 1-2, 49 Oxford 3, and 56 Oxford 4-5. Age ( P = 0.017), vaginal delivery ( P = 0.008), and prior pelvic surgery ( P = 0.032) were associated with increased Oxford grades. Obstructive defecation symptoms and dyssynergic defecation were observed at relatively high rates across groups. Increased RI grades were associated with less anal relaxation at simulated defecation yet, higher rates of normal balloon expulsion ( P < 0.05), linked to diminished anal sphincter. Indeed, increased RI grades were associated with worsening fecal incontinence severity, attributed to higher rates of anal hypotension. Levator ani laxity, defined by increased levator hiatus length and its excessive descent at straining, was associated with increasing RI grades, independent of age, history of vaginal delivery, and pelvic surgeries and could independently predict increased RI grades. Concurrent anterior and posterior compartments, and visceral prolapse were associated with higher Oxford grades. DISCUSSION Our data suggest that decline in pelvic floor integrity with abnormal levator ani laxity is associated with increased RI grades, a process that is independent of age, history of vaginal deliveries, and/or pelvic surgeries, and perhaps related to dyssynergic defecation.

Radiopaque marker colonic transit study in the pediatric population BSPGHAN Motility Working Group consensus statement. Neurogastroenterol Motil 2024; 36:e14776. [PMID: 38454312 DOI: 10.1111/nmo.14776] [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: 08/28/2023] [Revised: 02/25/2024] [Accepted: 02/26/2024] [Indexed: 03/09/2024]
Abstract
Functional constipation (FC) is a common condition in childhood in the United Kingdom and worldwide. Various radiological approaches have been established for diagnostic purposes. The radiopaque marker study (ROMS) is universally accepted and used to assess colonic transit time (CTT) in children with FC. Despite being widely used, there is a lack of standardization with various technical protocols, reproducibility of different populations, the purpose for using investigation, variance in the number of markers used, the amount of study days and calculations, the need to empty the colon before performing the test, and whether to perform on medication or off, or the use of specific diets. As part of the British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) motility working group (MWG), we decided to explore further into the evidence, in order to provide guidance regarding the use of ROMS in dealing with FC in the pediatric population.

Abstract
Common disorders of the gastrointestinal (GI) tract, such as gastroesophageal reflux/disease (GER/D) and constipation, are frequent causes for seeking medical support in infants. Diagnostic workup must ensure that diagnosed diseases are responsible for such complaints, thus enabling appropriate therapy. In this context assessment consists of clinical examination, functional tests, and imaging, which should be done in a staged manner. Close cooperation between clinicians and clinical radiologists enables optimal diagnostics, thus forming the basis for appropriate therapy.

Abstract
ABSTRACT We discuss 10 cases where the qualitative evaluation of hard stool in the rectum with point-of-care ultrasound helped guide enema administration in a pediatric emergency department. Point-of-care ultrasound findings were especially valuable in cases where the presenting symptoms were undifferentiated, a language barrier was present, or the guardian and child denied that constipation was an active problem. When sodium phosphate enema administration was done in the pediatric emergency department, evacuation of the rectal stool burden was observed in most cases before final disposition.

Regional homogeneity alterations in patients with functional constipation and their associations with gene expression profiles. Cereb Cortex 2024; 34:bhad403. [PMID: 37981661 DOI: 10.1093/cercor/bhad403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 09/24/2023] [Accepted: 09/25/2023] [Indexed: 11/21/2023] Open
Abstract
Functional constipation, a highly prevalent functional gastrointestinal disorder, often accompanies by mental and psychological disorders. Previous neuroimaging studies have demonstrated brain functional and structural alterations in patients with functional constipation. However, little is known about whether and how regional homogeneity is altered in these patients. Moreover, the potential genetic mechanisms associated with these alterations remain largely unknown. The study included 73 patients with functional constipation and 68 healthy controls, and regional homogeneity comparison was conducted to identify the abnormal spontaneous brain activities in patients with functional constipation. Using Allen Human Brain Atlas, we further investigated gene expression profiles associated with regional homogeneity alterations in functional constipation patients with partial least squares regression analysis applied. Compared with healthy controls, functional constipation patients demonstrated significantly decreased regional homogeneity in both bilateral caudate nucleus, putamen, anterior insula, thalamus and right middle cingulate cortex, supplementary motor area, and increased regional homogeneity in the bilateral orbitofrontal cortex. Genes related to synaptic signaling, central nervous system development, fatty acid metabolism, and immunity were spatially correlated with abnormal regional homogeneity patterns. Our findings showed significant regional homogeneity alterations in functional constipation patients, and the changes may be caused by complex polygenetic and poly-pathway mechanisms, which provides a new perspective on functional constipation's pathophysiology.

High-resolution anorectal manometry for diagnosing obstructed defecation syndrome associated with moderate rectocele compared to healthy individuals. BMC Gastroenterol 2024; 24:16. [PMID: 38178041 PMCID: PMC10768498 DOI: 10.1186/s12876-023-03063-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 11/25/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND Few studies have investigated healthy female individuals (HFI) and those with obstructed defecation syndrome associated with moderate rectocele in women (MRW), identified using three-dimensional high-resolution anorectal manometry (3D HRAM) parameters that correlate with age stratification. OBJECTIVE We aimed to explore the clinical diagnostic values of the MRW and HFI groups using 3D HRAM parameters related to age stratification. METHODS A prospective non-randomized controlled trial involving 128 cases from the MRW (treatment group, 68 cases) and HFI (control group, 60 cases) groups was conducted using 3D HRAM parameters at Tianjin Union Medical Center between January 2017 and June 2022, and patients were divided into two subgroups based on their ages: the ≥50 and < 50 years subgroups. RESULTS Multivariate binary logistic regression analysis showed that age (P = 0.024) and rectoanal inhibitory reflex (P = 0.001) were independent factors affecting the disease in the MRW group. Compared to the HFI group, the receiver operating characteristic (ROC) curve demonstrated that the 3D HRAM parameters exhibited a higher diagnostic value for age (Youden index = 0.31), urge to defecate (Youden index = 0.24), and rectoanal pressure differential (Youden index = 0.21) in the MRW group. CONCLUSIONS Compared to the HFI group, the ROC curve of the 3D HRAM parameters suggests that age, urge to defecate, and rectoanal pressure differential in the MRW group have a significant diagnostic value. Because the Youden index is lower, 3D HRAM cannot be considered the gold standard method for diagnosing MRW.

A novel perspective on constipation secondary to sigmoidocele: a retrospective study. Abdom Radiol (NY) 2024; 49:249-257. [PMID: 37979005 DOI: 10.1007/s00261-023-04104-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 10/12/2023] [Accepted: 10/18/2023] [Indexed: 11/19/2023]
Abstract
PURPOSE Sigmoidocele, which is a type of obstructed defecation syndrome (ODS), is a peritoneal hernia of the pelvic floor that has been seldom studied individually. This study investigated the anatomic characteristics of sigmoidocele based on imaging features. METHODS This retrospective cohort population comprised adult patients with ODS who underwent defecography between December 2017 and July 2020. Sigmoidocele was classified based on existing criteria. Novel radiological parameters including the vertical distance descended by the sigmoid colon from rest to maximum straining (RMS) and from the inferior border of the sigmoid colon to the superior border of the rectum at maximum straining (MSR) were measured. RESULTS Among 275 patients with sigmoidocele, 251 (91.6%) were female. The mean age was 51.53±12.99 years. We classified 26, 205, and 44 cases as grades I, II, and III, respectively. Patients with more severe sigmoidocele had greater sigmoid colon mobility (RMS: 19.13±8.54 mm, 34.45±14.51 mm, and 48.70±20.05 mm for grades I, II, and III, respectively; p < 0.001) and more pronounced compression of the rectum by the sigmoid colon at maximum straining (MSR: 35.23±8.44 mm, 26.33±13.29 mm, and 15.18±18.00 mm, respectively; p < 0.001). We regrouped the patients based on sigmoid colon alignment. Type L patients had the most severe constipation. CONCLUSION Our study presents a novel sigmoidocele classification. The anatomic appearance and location of the herniated sigmoid colon observed using fluoroscopy during defecation may help improve the clinical awareness of ODS caused by sigmoidocele.

Abstract
AIMS The aim of this retrospective study was to try to find correlations between different diagnoses established by clinical examination, anorectal manometry and MRI-defecography and, the association with psychiatric disorders. METHODS 44 patients (median age 53.81 years) presenting with intestinal motility disorders and who underwent clinical, biological and psychiatric examination, dynamic defecographic-MRI (resting, squeezing, straining, defecation and evacuation phases), anorectal manometry, colonoscopy. MRI was performed using the 1,5 T. RESULTS MRI-defecography revealed the following changes: anismus (16), rectocele (12), pelvic floor dysfunction (6), peritoneocele (2), cervical-cystic-ptosis (1), rectal prolapse (6), and in 1 case the examination was normal. Hypertonic anal sphincter (16) and lack of defecation reflex (12) at anorectal manometry correlated with anismus in all patients at MRI-defecography. Lack of inhibitor anal reflex (6) was associated with rectocele (4), cervix-cysto-ptosis (1) and peritoneocele (2). Anxiety (11), depression (6) and anxiety-depressive disorders (10) were found in 27/44, somatization disorders in 9/44 and no psychiatric changes in 8/44 cases. CONCLUSION As multiparous women are at risk for outlet obstruction constipation, MRI-defecography is suggested in this category. There is good correlation between diagnosis using anorectal manometry and MRI-defecography in patients with terminal constipation and anismus. Lower defecation dysfunction is often associated with psychiatric disorders.

Transabdominal ultrasound of rectal diameter in healthy infants: a prospective cohort study during the first year of life. J Paediatr Child Health 2023; 59:1021-1027. [PMID: 37249409 DOI: 10.1111/jpc.16447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 05/17/2023] [Accepted: 05/19/2023] [Indexed: 05/31/2023]
Abstract
AIM Transabdominal rectal ultrasound (TRU) is used to measure transverse rectal diameter (TRD) in order to diagnose functional constipation (FC) and megarectum, and to evaluate treatment. The proposed cut-off value is 3.0 cm. Currently, no standardised values exist for children below the age of 4. We used repeated TRUs to establish reference TRD values in healthy infants and to describe rectal diameter in infants with FC. METHODS This prospective observational cohort study enrolled healthy term babies from a maternity department. TRD measurements were taken at 2 and 12 months of age, and questionnaires completed in interviews helped diagnose FC according to Rome III criteria. RESULTS Two hundred TRUs were performed on 110 infants (62 males). In infants without FC anytime, the mean TRD at 2 months was 1.56 (SD 0.32) cm and at 12 months 1.78 (0.47) cm, while the 95th percentiles were 2.26 and 2.64 cm, respectively. In 77 infants with two TRUs, the mean increase was 0.21 cm (95% confidence interval: 0.099-0.318). Thirteen infants were diagnosed with FC during the study period. At 2 and 12 months of age, there was no difference in TRD between infants with and without FC. CONCLUSION TRD increased from 2 to 12 months. We suggest 2.3 cm as an upper limit for normal TRD at 2 months and 2.6 cm at 12 months. Infants diagnosed with FC did not have a greater TRD than infants without, either before or after treatment. Further studies are needed to evaluate the usefulness of TRU in infants with FC or megarectum.

To what extent are anorectal function tests comparable? A study comparing digital rectal examination, anal electromyography, 3-dimensional high-resolution anal manometry, and transperineal ultrasound. Int J Colorectal Dis 2023; 38:12. [PMID: 36645523 PMCID: PMC9842578 DOI: 10.1007/s00384-022-04304-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 12/07/2022] [Indexed: 01/17/2023]
Abstract
BACKGROUND Anorectal function tests are helpful for objective investigation of anorectal (dys)function. A variety of tests are available, but there is no recommendation when to perform which test. Furthermore, which test is the most accurate is controversial and the correlation between these tests is not very clear. The aim of our study was to examine the correlation of anal pressures and the possibility to diagnose pelvic floor dyssynergia between digital rectal examination (DRE) and several anorectal function tests. METHODS Between January 2020 and April 2022, all men and women aged 18 to 80 years, treated at the Proctos Clinic, who were referred for pelvic floor physical therapy (PFPT) by the surgeon and underwent anorectal function tests, were included. DRE was performed to establish the anal pressure at rest and during squeeze and straining. Anorectal function tests included 3D high-resolution anal manometry (3D-HRAM), balloon expulsion test (BET), transperineal ultrasound (TPUS), and surface electromyography (s-EMG). RESULTS A total of 50 patients, 37 (74%) females, were included. Median age was 51 years. Twenty-three (62%) females had a history of two or more vaginal deliveries. The most frequent reason for referral for PFPT was fecal incontinence in 27 (54%) patients. The assessed pressures and pelvic floor function measured with DRE by the surgeon and the pelvic floor physical therapist during rest, squeeze, and straining correlated in 78%, 78%, and 84%, respectively. Correlation between DRE and 3D-HRAM or s-EMG was better for squeeze pressures than resting pressures. The correlation between s-EMG and 3D-HRAM was better during squeeze than at rest with an agreement of 59% and 37%, respectively. CONCLUSION DRE by an experienced investigator is of sufficient value for daily clinical practice to detect dyssynergia and to measure sphincter tone. Commonly performed anorectal function tests correlate poorly with DRE and with other anorectal function tests. When conservative treatment fails, further investigation is warranted; however, these results should be interpreted with caution. WHAT DOES THIS PAPER ADD TO THE LITERATURE?: Anorectal function tests such as the 3D high-resolution anorectal manometry, balloon expulsion test, surface electromyography, and transperineal ultrasound are all frequently performed in the diagnostic workup in patients with defecation disorders. No previous study has compared these tests regarding their outcomes, nor has the interrater agreement been measured regarding the digital rectal examination by two experienced observers. Furthermore, transperineal ultrasound is in all probability not frequently used and therefore underexposed in the diagnostic workup of patients with dyssynergic defecation.

Abstract
Three-dimensional high-resolution anorectal manometry (3DHRAM) is a new technique that can explore anorectal disorders and provide interesting topographic data for the diagnosis of pelvic floor disorders such as paradoxical puborectalis syndrome (PPS). Our object was to evaluate whether 3DHRAM can reliably diagnose PPS already diagnosed with X-ray defaecography, which is considered to be the gold standard. All patients being tested in our department for dyschezia by 3D-HRAM and X-ray defecography were eligible for the study. The 3DHRAM results were compared with X-ray defecography. The sensitivity, specificity, and positive and negative predictive values were calculated for various 3DHRAM criteria to propose a diagnostic strategy for PPS. Twenty-three patients presented with PPS on X-ray defaecography. On 3DHRAM, according to our diagnostic strategy, the kappa value was 0.706, with a positive predictive value of 71.88% [95% CI, 53.02-85.60], a specificity of 80.43% [95% CI, 65.62-90.13], a sensibility of 95.83% [95% CI, 76.98-99.78], and area under curve value was 0.922. In this study, 3DHRAM was used to diagnose PPS with the same degree of reliability as X-ray defaecography, and we confirmed its use in the diagnosis of pelvic floor disorders. Further studies will be necessary to define classifications for these new anatomic data from 3DHRAM.

Abstract
BACKGROUND & AIMS The utility of high-resolution anorectal manometry (HR-ARM) for diagnosing defecatory disorders (DDs) is unclear because healthy people may have features of dyssynergia. We aimed to identify objective diagnostic criteria for DD and to ascertain the utility of HR-ARM for diagnosing DD. METHODS Constipated patients were assessed with HR-ARM and rectal balloon expulsion time (BET), and a subset underwent defecography. Normal values were established by assessing 184 sex-matched healthy individuals. Logistic regression models evaluated the association of abnormal HR-ARM findings with prolonged BET and reduced rectal evacuation (determined by defecography). RESULTS A total of 474 constipated individuals (420 women) underwent HR-ARM and BET, and 158 underwent defecography. BET was prolonged, suggesting a DD, for 152 patients (32%). Rectal evacuation was lower for patients with prolonged vs normal BET. A lower rectoanal gradient during evacuation, reduced anal squeeze increment, and reduced rectal sensation were independently associated with abnormal BETs; the rectoanal gradient was 36% sensitive and 85% specific for prolonged BET. A lower rectoanal gradient and prolonged BET were independently associated with reduced evacuation. Among constipated patients, the probability of reduced rectal evacuation was 14% when the gradient and BET were both normal, 45% when either was abnormal, and 75% when both variables were abnormal. CONCLUSIONS HR-ARM, BET, and defecography findings were concordant for constipated patients, and reduced rectoanal gradient was the best HR-ARM predictor of prolonged BET or reduced rectal evacuation. Prolonged BET, reduced gradient, and reduced evacuation each independently supported a diagnosis of DD in constipated patients. We propose the terms probable DD for patients with an isolated abnormal gradient or BET and definite DD for patients with abnormal results from both tests.

Abstract
Purpose To compare examination quality and acceptability of three different low-volume bowel preparation regimens differing in scheduling of the oral administration of a Macrogol-based solution, in patients undergoing computed tomographic colonography (CTC). The secondary aim was to compare CTC quality according to anatomical and patient variables (dolichocolon, colonic diverticulosis, functional and secondary constipation). Methods One-hundred-eighty patients were randomized into one of three regimens where PEG was administered, respectively: in a single dose the day prior to (A), or in a fractionated dose 2 (B) and 3 days (C) before the examination. Two experienced radiologists evaluated fecal tagging (FT) density and homogeneity both qualitatively and quantitatively by assessing mean segment density (MSD) and relative standard deviation (RSD). Tolerance to the regimens and patient variables were also recorded. Results Compared to B and C, regimen A showed a lower percentage of segments with inadequate FT and a significantly higher median FT density and/or homogeneity scores as well as significantly higher MSD values in some colonic segments. No statistically significant differences were found in tolerance of the preparations. A higher number of inadequate segments were observed in patients with dolichocolon (p < 0.01) and secondary constipation (p < 0.01). Interobserver agreement was high for the assessment of both FT density (k = 0.887) and homogeneity (k = 0.852). Conclusion The best examination quality was obtained when PEG was administered the day before CTC in a single session. The presence of dolichocolon and secondary constipation represent a risk factor for the presence of inadequately tagged colonic segments.

Abstract
ABSTRACT Schaaf-Yang syndrome is a genetic disorder characterized by delayed psychomotor development, hypotonia, intellectual disability, feeding difficulties, and variable dysmorphic facial features. It is an extremely rare disorder with over 250 cases reported in the medical literature. This condition has been determined to be inherited by an autosomal dominant pattern. We present colon transit scintigraphy of a 6-year-old boy with history of chronic constipation with poor response to medical treatment, clinical characteristics, and gene mutations consistent with this syndrome. After oral administration of 111In-DTPA, planar and SPECT/CT images showed rapid proximal colonic transit and anorectal retention.

Aberrant functional brain network dynamics in patients with functional constipation. Hum Brain Mapp 2021; 42:5985-5999.

Abstract
The aberrant static functional connectivity of brain network has been widely investigated in patients with functional constipation (FCon). However, the dynamics of brain functional connectivity in FCon patients remained unknown. This study aimed to detect the brain dynamics of functional connectivity states and network topological organizations of FCon patients and investigate the correlations of the aberrant brain dynamics with symptom severity. Eighty-three FCon patients and 80 healthy subjects (HS) were included in data analysis. The spatial group independent component analysis, sliding-window approach, k-means clustering, and graph-theoretic analysis were applied to investigate the dynamic temporal properties and coupling patterns of functional connectivity states, as well as the time-variation of network topological organizations in FCon patients. Four reoccurring functional connectivity states were identified in k-means clustering analysis. Compared to HS, FCon patients manifested the lower occurrence rate and mean dwell time in the state with a complex connection between default mode network and cognitive control network, as well as the aberrant anterior insula-cortical coupling patterns in this state, which were significantly correlated with the symptom severity. The graph-theoretic analysis demonstrated that FCon patients had higher sample entropy at the nodal efficiency of anterior insula than HS. The current findings provided dynamic perspectives for understanding the brain connectome of FCon and laid the foundation for the potential treatment of FCon based on brain connectomics.

Abstract
ABSTRACT We used dynamic pelvic floor ultrasound to investigate the relationship between obstructed defecation symptom (ODS) severity and the degree of rectal hypermobility/folding. In this retrospective study, women who presented with ODS from October 2017 to January 2019 and underwent an interview, pelvic examination, and pelvic floor ultrasound were recruited. Patients were diagnosed with abdominal constipation, dyssynergia, or pelvic constipation. Pelvic constipation patients were categorized based on their reported frequency of incomplete emptying of stool (<50% or ≥50% of bowel movements) representing mild and severe ODS, respectively. Using dynamic ultrasound, rectal hypermobility was quantified via rectovaginal septum length at rest and Valsalva and its compression ratio, where shorter lengths and larger compression ratios are indicative of increased rectal hypermobility. One hundred twenty-one patients (41 with abdominal constipation, 7 with dyssynergia, and 73 with pelvic constipation) were included. Compression ratios were higher in women with severe versus mild ODS (17.36 ± 16.89 vs 36.38 ± 25.82, P = 0.0039). The risk of having severe symptoms was 4 times greater (odds ratio = 4.2, 95% confidence interval = 1.4 to 12.6, P = 0.01) among those with a high compression ratio (≥20%) after controlling for age, body mass index, and levator plate descent angle. Incomplete emptying was weakly, positively, linearly correlated with rectal hypermobility/folding (r = -0.2724, -0.3767 to 0.3922, and P = 0.0197, 0.0010, 0.0006, respectively). Women with more severe ODS experienced more rectal hypermobility/folding as measured via dynamic ultrasound-a cheaper, effective alternative to magnetic resonance defecography for evaluation of obstructed defecation.

Abstract
OBJECTIVE Functional constipation (FC) is a common gastrointestinal disorder. Anxiety and/or depressive disorders are common in patients with FC (FCAD). Brain dysfunction may play a role in FC, but the contribution of comorbid anxiety and/or depression in patients with FC is poorly understood. METHODS Sixty-five FC patients and 42 healthy controls (HCs) were recruited, and a hierarchical clustering algorithm was used to classify FC patients into FCAD and patients without anxiety/depressive status (FCNAD) based on neuropsychological assessment. Resting-state functional magnetic resonance imaging measures including fractional amplitude of low-frequency fluctuation (fALFF) and functional connectivity were used to investigate brain functional differences. RESULTS Thirty-seven patients were classified as FCAD, and 28 patients were classified as FCNAD; as compared with HC, both groups showed decreased activity (fALFF) in the perigenual anterior cingulate cortex (pACC), dorsomedial prefrontal cortex (DMPFC), and precuneus; enhanced precentral gyrus-thalamus connectivity and attenuated precuneus-thalamus connectivity in FCAD/FCNAD highlighted the thalamus as a critical connectivity node in the brain network (pFWE < .05). In comparison with FCNAD/HC, the FCAD group also had decreased fALFF in the orbitofrontal cortex (OFC) and thalamus, and increased OFC-hippocampus connectivity. In the FCNAD group, brain activities (pACC/DMPFC) and connection (precuneus-thalamus) had correlations only with symptoms; in the FCAD group, brain activities (OFC, pACC/DMPFC) and connectivities (OFC-hippocampus/precentral gyrus-thalamus) showed correlations with both constipation symptoms and anxiety/depressive status ratings. Mediation analysis indicated that the relationship between abdominal distension and OFC activity was completely mediated by anxiety in FCAD. CONCLUSIONS These findings provide evidence of differences in brain activity and functional connectivity between FCAD and FCNAD, potentially providing important clues for improving treatment strategies.

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
OBJECTIVES Constipation is a common problem in children, and most of the time, the cause is defined as functional. Our hypothesis is that children with functional refractory constipation had anatomic alterations of the colon. METHODS All children with chronic refractory constipation who visited our centre underwent accurate clinical examination, contrast enema (CE), anorectal manometry (ARM) and rectal suction biopsies (RSB). In case of functional constipation, three operators measured the size of the colon using radiograms and calculated the ratio based on the width of the second lumbar vertebra. The measurements carried out were compared with those reported in the literature on patients of the same age without constipation. RESULTS Over a period of 24 months, 69 patients with chronic refractory constipation, aged between 1 and 14 years, visited our department. A CE was performed on 67, and 2 were excluded because of anal stenosis. Sixty-five underwent anorectal manometry. Rectal suction biopsies were needed in 14 children, and 2 of them were found to have colonic aganglionosis. After a complete evaluation, 57 (82.61%) patients were diagnosed having functional constipation. By comparing the data of the patients with those of normal children reported by the other authors, we found that none of the measurements was statistically significant except for the rectosigmoid length: the mean value in one-year-old patients was 19.03 vs. 9.75, and in older children, it was 19.46 vs. 9.59. CONCLUSIONS Recognizing an anatomic anomaly in patients suffering from functional constipation is important for specific treatment, especially when the ratio (rectosigmoid length/L2) is higher than 15.

Abstract
RATIONALE Intestinal hypoganglionosis most commonly presents in infancy or childhood, with only a few cases reported in adults. Those are mainly diagnosed after elective surgery for long-standing constipation and megacolon. PATIENT CONCERNS We report a case of a 48-year-old female from China who presented with symptoms of discontinuation of bowel movements for 2 months. A hard, round mass could be felt in her right lower abdomen. DIAGNOSIS The following examination methods diagnosed acquired segmental sigmoid hypoganglionosis. An abdominal computed tomography revealed a dilatation of the colon and suspicious wall thickening of the sigmoid colon. Anorectal manometry revealed relaxation of the anal sphincter. Histological examination revealed lower numbers and the degeneration of ganglion cells. INTERVENTIONS Sigmoidectomy and transverse colostomy. OUTCOMES The patient recovered well from surgery. Three months after the surgery, barium enema revealed a recovery in colorectal dilatation. LESSONS This case could help raise awareness of acquired segmental hypoganglionosis. Resection of TZ and enterostomy presents an effective remission strategy for patients at risk of anastomotic leakage due to poor intestinal conditions.

Comparison of changes in rectal area and volume during MR evacuation proctography in healthy and constipated adults. Neurogastroenterol Motil 2019; 31:e13608. [PMID: 31025437 PMCID: PMC6559848 DOI: 10.1111/nmo.13608] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Revised: 03/22/2019] [Accepted: 04/09/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND During proctography, rectal emptying is visually estimated by the reduction in rectal area. The correlation between changes in rectal area, which is a surrogate measure of volume, is unclear. Our aims were to compare the change in rectal area and volume during magnetic resonance (MR) proctography and to compare these parameters with rectal balloon expulsion time (BET). METHODS In 49 healthy and 46 constipated participants, we measured BET and rectal area and volume with a software program before and after participants expelled rectal gel during proctography. KEY RESULTS All participants completed both tests; six healthy and 17 constipated patients had a prolonged (>60 seconds) BET. During evacuation, the reduction in rectal area and volume was lower in participants with an abnormal than a normal BET (P < 0.01). The reduction in rectal area and volume were strongly correlated (r = 0.93, P < 0.001) and equivalent for identifying participants with abnormal BET. Among participants with less evacuation, the reduction in rectal area underestimated the reduction in rectal volume. A rectocele larger than 2 cm was observed in eight of 18 (44%) participants in whom the difference between change in volume and area was ˃10% but only 14 of 77 (18%) participants in whom the difference was ≤10% (P = 0.03). CONCLUSIONS Measured with MR proctography, the rectal area is reasonably accurate for quantifying rectal emptying and equivalent to rectal volume for distinguishing between normal and abnormal BET. When evacuation is reduced, the change in rectal area may underestimate the change in rectal volume.

Abstract
BACKGROUND Fecal incontinence (FI) and chronic constipation (CC) are disabling symptoms that cause a significant public health problem. The pathophysiology of combined constipation and FI is not fully understood. Our aim was to delineate the clinical, physiological and anatomical factors that may contribute to the association of FI and CC. METHODS A retrospective study was performed in a pelvic floor unit in a tertiary medical center. Consecutive female patients diagnosed with CC were included, and further divided into two groups according to the co-occurrence of FI. Demographic characteristics, anorectal physiology (obtained by manometry) and pelvic anatomical pathology (as assessed by dynamic pelvic ultrasound) were recorded and subsequently compared. RESULTS A total of 267 women were included in the study. Of those, 62 patients (23%) had an associated FI (CCFI). The CCFI group had higher body mass index (BMI) levels and a trend toward younger average age as compared to the group without FI (CCNFI). The number of vaginal and instrumental deliveries was similar in both groups. Anal resting and squeeze pressures were significantly lower in the CCFI group (64 ± 21 vs 48 ± 18, p = 0.004 and 141 ± 136.2 vs. 97.5 ± 38.6, p = 0.02, respectively). Rectal sensation abnormalities were common, but did not differ between both groups. Dyssynergic defecation and rectocele were more common in the CCNFI group (68% vs. 51%, p = 0.04 and 39% vs. 24%, p = 0/045, respectively. CONCLUSIONS Lower anal pressures and higher BMI were found among women with coexisting FI and CC. Pelvic floor anatomical and functional abnormalities are common in women diagnosed with CC and FI, but dyssynergia and diagnosis of significant rectocele, which cause obstructed defecation, were more common in the CCNFI group.

Efficacy of Polydextrose Supplementation on Colonic Transit Time, Bowel Movements, and Gastrointestinal Symptoms in Adults: A Double-Blind, Randomized, Placebo-Controlled Trial. Nutrients 2019; 11:nu11020439. [PMID: 30791557 PMCID: PMC6412485 DOI: 10.3390/nu11020439] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 02/08/2019] [Accepted: 02/15/2019] [Indexed: 12/17/2022] Open
Abstract
The addition of fiber is one of the most important dietary means to relieve constipation through lifestyle modification. Polydextrose (PDX) has been reported in several studies to increase fecal bulk, soften stools, and increase the number of defecations. However, there are few studies on the effect of PDX on colonic transit time (CTT). Therefore, the aim of this study was to demonstrate the effect of PDX on CTT and other aspects of gastrointestinal function during two weeks (Day 1 to Day 14), preceded by a 2-week run-in period (Day -14 to Day -1). A total of 192 adults who were diagnosed with functional constipation per Rome III criteria were recruited for the study. Participants were randomized equally into 4 groups (12 g, 8 g, or 4 g of PDX or placebo per day). The primary endpoint was CTT, assessed using radio-opaque markers and abdominal X-rays on Day 0, the baseline; and Day 15, the end of the intervention. Secondary outcomes that were measured using inventories were the patient assessment of constipation symptoms and quality of life, bowel function index, relief of constipation, bowel movement frequency (BMF), stool consistency, degree of straining, and proportion of bowel movements. Ancillary parameters and harms were also evaluated. The recruited population was not sufficiently constipated (e.g., baseline values for CTT and BMF of 42 h and 8.7 BMF/week, respectively). Despite this limitation, our results demonstrated an increased number of bowel movements when supplemented with PDX at a dosage of 12 g per day for 2 weeks. This dosage also consistently improved the secondary outcomes that were measured using inventories at Day 15, compared with the baseline. No serious or significant adverse events were reported during the study.

Abstract
Hypermagnesemia is generally considered an exceptional iatrogenic condition usually caused by magnesium-containing cathartics. In particular, this condition often develops when magnesium-containing cathartics are administered to elderly patients with renal insufficiency or bowel movement dysfunction. Although magnesium oxide (MgO) is widely prescribed as a laxative, serum magnesium concentration has not been examined in most cases. In this report, we present the cases of four elderly patients with constipation and symptomatic hypermagnesemia caused by MgO ingestion, one of which had a lethal course. All of the patients were older than 65 years and with renal dysfunction. In addition, they had difficulties in expressing their symptoms because of cerebrovascular events or dementia. These cases suggest that hypermagnesemia caused by magnesium-containing cathartics is more likely to develop than previously recognized and that physicians should be aware that patients with chronic kidney disease and the elderly are at risk of hypermagnesemia on magnesium administration. We recommend serum magnesium monitoring for high-risk patients after initial prescription or dose increase.

Abstract
BACKGROUND The aim of the present study was to assess the relationship between symptoms of obstructed defecation and findings on magnetic resonance (MR) defecography in males with obstructed defecation syndrome (ODS). METHODS Thirty-six males with ODS who underwent MR defecography at our institution between March 2013 and February 2016 were asked in a telephone interview about their symptoms and subsequent treatment, either medical or surgical. Patients were divided into 2 groups, one with anismus (Group 1) and one with prolapse without anismus (Group 2). The interaction between ODS type and symptoms with MR findings was assessed by multivariate analysis for categorical data using a hierarchical log-linear model. MR imaging findings included lateral and/or posterior rectocele, rectal prolapse, intussusception, ballooning of levator hiatus with impingement of pelvic organs and dyskinetic puborectalis muscle. RESULTS There were 21 males with ODS due to anismus (Group 1) and 15 with ODS due to rectal prolapse/intussusception (Group 2). Mean age of the entire group was 53.6 ± 4.1 years (range 18-77 years). Patients in Group 1 were slightly older than those in Group 2 (age peak, sixth decade in 47.6 vs 20.0%, p < 0.05). Symptoms most frequently associated with Group 1 patients included small volume and hard feces (85.0%, p < 0.01), excessive strain at stool (81.0%, p < 0.05), tenesmus and fecaloma formation (57.1 and 42.9%, p < 0.05); symptoms most frequently associated with Group 2 patients included mucous discharge, rectal bleeding and pain (86.7%, p < 0.05), prolonged toilet time (73.3%, p < 0.05), fragmented evacuation with or without digitation (66.7%, p < 0.005). Voiding outflow obstruction was more frequent in Group 1 (19.0 vs 13.3%; p < 0.05), while non-bacterial prostatitis and sexual dysfunction prevailed in Group 2 (26.7 and 46.7%, p < 0.05). At MR defecography, two major categories of findings were detected: a dyskinetic pattern (Type 1), seen in all Group 1 patients, which was characterized by non-relaxing puborectalis muscle, sand-glass configuration of the anorectum, poor emptying rate, limited pelvic floor descent and final residue ≥ 2/3; and a prolapsing pattern (Type 2), seen in all Group 2 patients, which was characterized by rectal prolapse/intussusception, ballooning of the levator hiatus with impingement of the rectal floor and prostatic base, excessive pelvic floor descent and residue ≤ 1/2. Posterolateral outpouching defined as perineal hernia was present in 28.6% of patients in Group 1 and were absent in Group 2. The average levator plate angle on straining differed significantly in the two patterns (21.3° ± 4.1 in Group 1 vs 65.6° ± 8.1 in Group 2; p < 0.05). Responses to the phone interview were obtained from 31 patients (18 of Group 1 and 13 of Group 2, response rate, 86.1%). Patients of Group 1 were always treated without surgery (i.e., biofeedback, dietary regimen, laxatives and/or enemas) which resulted in symptomatic improvement in 12/18 cases (66.6%). Of the patients in Group 2, 2/13 (15.3) underwent surgical repair, consisting of stapled transanal rectal resection (STARR) which resulted in symptom recurrence after 6 months and laparoscopic ventral rectopexy which resulted in symptom improvement. The other 11 patients of Group 2 were treated without surgery with symptoms improvement in 3 (27.3%). CONCLUSIONS The appearance of various abnormalities at MR defecography in men with ODS shows 2 distinct patterns which may have potential relevance for treatment planning, whether conservative or surgical.

Abstract
INTRODUCTION AND HYPOTHESIS Rectocele is common in parous women but also seen in nulliparae. This study was designed to investigate the association between vaginal parity and descent of the rectal ampulla/rectocele depth as determined by translabial ultrasound (TLUS). METHODS This retrospective observational study involved 1296 women seen in a urogynaecological centre. All had undergone an interview, clinical examination and 4D ultrasound (US) imaging supine and after voiding. Offline analysis of volume data was undertaken blinded against other data. Rectal ampulla position and rectocele depth were measured on Valsalva. A pocket depth of 10 mm was used as a cutoff to define rectocele on imaging. RESULTS Most women presented with prolapse (53%, n = 686); 810 (63%) complained of obstructed defecation (OD). Clinically, 53% (n = 690) had posterior-compartment prolapse with a mean Bp of -1 [standard deviation (SD)1.5; -3 to 9 cm]. Mean descent of the rectal ampulla was 10 mm below the symphysis (SD 15.8; -50 to 41). A rectocele on imaging was found in 48% (n = 618). On univariate analysis, OD symptoms were strongly associated with rectal descent, rectocele depth and rectocele on imaging (all P < 0.001). The prevalence of a rectocele seen on imaging increased with vaginal parity (P < 0.001). One-way analysis of variance (ANOVA) of vaginal parity against rectal descent and rectocele depth showed a dose-response relationship (both P < 0.001). CONCLUSIONS Vaginal parity was strongly associated with descent of the rectal ampulla and rectocele depth. This relationship approximated dose-response characteristics, with the greatest effect due to the first vaginal delivery.

Abstract
BACKGROUND Constipation and fecal incontinence (FI) are common and are often evaluated with anorectal manometry. Three-dimensional high-resolution anorectal manometry (HRAM) is a promising technology; however, implementation has been limited by lack of metrics and unclear clinical utility. AIM To investigate the diagnostic utility of 3D HRAM compared to 2D HRAM. METHODS Three-dimensional HRAM studies performed from April 2012 to October 2013 were identified and re-interpreted by two blinded investigators examining 3D function. Disagreements were resolved by a third investigator. Puborectalis (PR) visualization, focal defects, and dyssynergy were reported. Differences between groups were analyzed with Fisher's exact test. Discordance was analyzed with McNemar Chi-square test. RESULTS Two hundred and twenty-one 3D HRAM studies were identified. Mean age and BMI were 52.2 ± 17.4 and 27.1 ± 7.5 years (81% female, 74% white). Most common indications for 3D HRAM were constipation (65%) and FI (28%). PR function was visualized in 81% (rest), 97% (squeeze), and 73% (strain). PR was visualized less often at rest in FI than constipation (68 vs. 85%, p = 0.007). Defects were identified twice as often in FI than constipation (19 vs. 10%, p = 0.113). Twenty-nine defects (86% anterior) were visualized on 3D HRAM. Inter-reader agreement was moderate for PR function (κ = 0.471), but fair for focal defects (κ = 0.304). CONCLUSIONS PR function and focal defects can be visualized on 3D-HRAM with added diagnostic benefit compared to 2D. Fair inter-reader agreement for focal defects highlights the need for quantitative metrics.

Abstract
BACKGROUND The treatment of fecal incontinence (FI) depends upon the dominant pathophysiology: impaired sphincter contractility or overflow due to pelvic floor dyssynergia and insufficient rectal emptying. In this study, we aimed to define the manometric and anorectal ultrasound characteristics in FI patients with and without constipation. METHODS We did a retrospective study of 365 anal manometries, performed between October 2012 and July 2015, in patients with FI. Clinical information was obtained from questionnaires. In 220 of these patients an anorectal ultrasound was also available. Key results : A high prevalence of self-reported constipation was seen in the total population of FI patients (66%). This number was lower (31%) when Rome IV criteria were applied. A very high percentage of manometric pelvic floor dyssynergia was seen in the total population with FI (81%). However, patients with FI and constipation did not show pelvic floor dyssynergia more often than patients without constipation. Anal resting pressure, squeeze pressure and anorectal pressure sensitivity were not different when comparing patients without and with constipation. The prevalence of a functional defecation disorder (FDD) in our study population of FI patients was 20%. Wexner score in this subgroup was lower compared with patients without FDD. Anal sphincter defects were more prevalent in women than men, and were associated with diminished sphincter contractility. CONCLUSION AND INFERENCES A very high percentage of FI patients showed manometric pelvic floor dyssynergia. The coexistence of fecal incontinence and constipation did not increase this percentage. KEY MESSAGES Constipation is a frequent and underestimated cause of FI. A correct diagnosis has a major impact on treatment. We aimed to characterize the manometric and transrectal ultrasound profile of FI patients with and without signs of coexisting constipation. - A very high percentage of incontinent patients showed pelvic floor dyssynergia, however no significant difference between the group with and the group without constipation was seen. Anal resting pressure, squeeze pressure and anorectal pressure sensitivity did not differ significantly either.

Abstract
Functional constipation and functional non-retentive faecal incontinence are common problems in childhood; these functional defaecation disorders are diagnosed according to the Rome IV criteria. Here we describe the role of an abdominal X-ray in diagnosing functional defaecation disorders, and address the limited additional value of a plain abdominal X-ray. In limited cases it may be helpful to determine colonic transit time using an abdominal X-ray to differentiate between functional constipation and functional non-retentive faecal incontinence. The diagnostic value of abdominal X-rays in children with functional abdominal pain will be discussed. The aims of this article are to explore ways of reducing unnecessary use of abdominal X-rays and reducing unnecessary radiation exposure in children with functional defaecation disorders and functional abdominal pain.

Abstract
An 84-year-old woman presented to her local emergency department for abdominal pain. Her medical history included hemodialysis in the treatment of chronic renal failure, Parkinson's disease, chronic atrial fibrillation, chronic constipation, appendicectomy and cholecystectomy. The patient complained of diffuse abdominal pain for 4 days, associated with nausea and vomiting in the last 24 hours. Physical examination revealed a soft and depressible abdomen, diffusely painful, without signs of peritoneal irritation. A digital rectal exam revealed large amount of stool in the rectal vault without palpable masses. Blood tests showed a creatinine level of 2.7 mg/dl due to chronic renal failure and the plain abdominal radiography revealed a dolichocolon completely contrasted. The patient denied the realization of any medical imaging-proofs with oral or rectal contrast. Reviewing home treatment, the patient was taking lanthanum carbonate (2 tablets of 750 mg per day) since 1 month ago, a drug that contrasts the digestive tract. Appreciating contrast in the colon, intestinal subocclusion was excluded and the clinical picture was attributed to her chronic constipation. In conclusion, it should be noted that lanthanum carbonate contrasts the digestive tract, with radiopaque appearance on the plain abdominal radiography and without any pathological significance.

Abstract
BACKGROUND Previous Literature has never evaluated the effectiveness of fiber intake after surgery for obstructed defecation in improving residual constipation and defecation urgency. METHODS From May 2010 to June 2011, 65 patients were randomly assigned to either the active group (N.=32) or placebo group (N.=33) receiving 3.5 g/day of pure Psyllium fiber or inert compound respectively. During the 6-month follow-up score systems were evaluated: Longo's Obstructed Defecation Syndrome Score, Cleveland Constipation Score; Wexner incontinence Score and Visual Analogic Scale. We also recorded the incidence of postoperative defecation urgency. RESULTS Active group reported less constipation at 1 week (ODS: 6.25±3.55 vs. 11.94±4.99, P<0.01-CCS: 6.59±2.65 vs. 15.10±3.33, P<0.01) and 6 months (ODS: 3.40±5.26 vs. 4.97±4.21, P<0.05-CCS: 5.00±3.82 vs. 6.63±3.68; P<0.01). Wexner Score was better at t-test in the treatment group (difference from baseline: 0.5 vs. 2.70, P<0.01 after 1 week and -0.17 vs. 1.33, P<0.01 after 6 months). Defecation urgency was less frequent in the treatment group (15.62% vs. 42.42%, P<0.05 at the χ2 Test). CONCLUSIONS Early treatment with Psyllium fiber improves early and 6 month results after stapled transanal rectal resection, both in terms of residual constipation and fecal incontinence. It also reduces postoperative defecation urgency.

Abstract
OBJECTIVE To report a case of a preschool girl who developed acute urinary retention associated with constipation. CASE DESCRIPTION A girl aged six years old presented a 24 hour history of inability to urinate. She was went twice to the emergency room during this period. In the first admission, 12 hours after the onset of the symptoms, she presented abdominal pain and acute urinary retention. After the drainage by urinary catheterization of 300 mL of clear urine, she presented relief of the symptoms and, as urinalysis had no change, the patient was discharged home. Twelve hours after the first visit, she returned to the emergency room complaining about the same symptoms. At physical examination, there was only a palpable and distended bladder up to the umbilicus with no other abnormalities. Again, a urinary catheterization was performed, which drained 450 mL of clear urine, with immediate relief of the symptoms. Urinalysis and urine culture had no abnormalities. During the anamnesis, the diagnosis of constipation was considered and a plain abdominal radiography was performed, which identified large amount of feces throughout the colon (fecal retention). An enema with a 12% glycerin solution was prescribed for three days. During follow-up, the child used laxatives and dietary modifications, this contributed to the resolution of the constipation. There were no other episodes of urinary retention after 6 months of follow-up. COMMENTS Acute urinary retention in children is a rare phenomenon and constipation should be considered as a cause.

New-onset rectoanal intussusception may not result in symptomatic improvement after laparoscopic ventral rectopexy for external rectal prolapse. Tech Coloproctol 2015; 20:101-7. [PMID: 26589950 DOI: 10.1007/s10151-015-1395-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2015] [Accepted: 09/15/2015] [Indexed: 01/05/2023]
Abstract
BACKGROUND This study was designed to assess defecatory function in patients who underwent laparoscopic ventral rectopexy (LVR) for external rectal prolapse (ERP). METHODS Thirty-one patients who underwent evacuation proctography 6 months postoperatively were assessed. Preoperative proctography had been performed in 21 patients of these patients. Defecatory function was evaluated using the constipation scoring system (CSS) and fecal incontinence severity index (FISI). RESULTS The findings of postoperative proctography revealed no full-thickness ERP in any patient, although in 10 patients the ERP was replaced by rectoanal intussusception (RAI). Of the 31 patients, 30 presented with fecal incontinence preoperatively. Ten of 30 had new-onset RAI. Six months postoperatively, a reduction of at least 50 % in the FISI score of the patients with new-onset RAI tended to be significantly smaller than in the patients without RAI (6/10 vs. 18/20, p = 0.141). Seventeen patients presented with obstructed defecation preoperatively. Seven of them had new-onset RAI. Six months postoperatively, a reduction of at least 50 % in their CSS score in the patients with new-onset RAI was significantly smaller than in patients without RAI (0/7 vs. 8/10, p = 0.002). CONCLUSIONS Evacuation proctography showed new-onset RAI in some patients with ERP who underwent LVR, which was associated with a lack of symptomatic improvement.

Colonic transit diagnostic test shows significant gastrointestinal hypomotility in clozapine-treated patients in comparison with subjects treated with other antipsychotics. Schizophr Res 2015; 166:207-11. [PMID: 26032569 DOI: 10.1016/j.schres.2015.05.025] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2015] [Revised: 05/11/2015] [Accepted: 05/13/2015] [Indexed: 12/19/2022]
Abstract
BACKGROUND Constipation occurs in 25-60% of the subjects during administration of the antipsychotic drug (AP) clozapine (CLZ). METHODS We used a colonic transit diagnostic test that quantifies in a single abdominal X-ray the number of silver O-ring markers out of 25 units ingested five days before. The quantity of markers is directly proportional to the degree of gastrointestinal hypomotility, and elimination of over 80% of the markers is considered normal. The test was applied to three groups of AP-treated subjects for at least three consecutive months: CLZ alone (n=45), CLZ+Other APs (n=28), and Other APs (n=64). RESULTS The number of remaining markers at day 5 (mean±S.D.) was significantly higher in the CLZ alone (10.8±10.6) and in the CLZ+Other APs (9.7±9.7) groups than in the Other AP group (4.5±6.7), Kruskal-Wallis test: p=0.004. No significant associations were found between the number of markers, age, AP dose and treatment duration. All subjects who passed <80% of markers - which approximately corresponds to the 60th percentile of marker elimination - showed a scattered marker distribution along the colon, thus suggesting colon inertia. In subjects with hypomotility, 38.5% of the CLZ group, 25% of the CLZ+Other APs group, and 25% of the Other APs group were negative for the Rome III clinical criteria of constipation, thus showing objective, not subjective, hypomotility. CONCLUSIONS This study objectively confirms significant gastrointestinal hypomotility associated with CLZ administration.

Abstract
OBJECTIVE The aim of this study was to assess clinical features and colonic transit patterns in Brazilian children with refractory constipation. METHODS From 2010 to 2013, 79 constipated patients received follow-up care in a tertiary hospital. Of these patients, 28 (aged 8-14 years) were refractory to conventional therapy and underwent a simplified visual method of nuclear colonic transit study, by ingestion of a liquid meal containing 9.25 MBq/kg of (99m)Tc-phytate. Abdominal static images were taken immediately and at two, six, 24, 30, and 48h after ingestion for qualitative analysis of the radio marker progression through the colon. RESULTS Two patterns of colonic transit were found: slow colonic transit (SCT, n=14), when images at 48h showed a larger part of the tracer remained in proximal and transverse colon, and distal retention (DR, n=14), when after 30h, the radio isotope passed the transverse colon and was retained in the rectosigmoid up to 48h. The SCT and DR group included, respectively, nine and ten males; median ages in the nuclear study of 11 and 10 years, p=0.207; median duration of constipation of seven and six years, p=0.599. Constipation appearing during first year age (p=0.04) and report of soft stools (p=0.02) were more common in SCT patients. Palpable abdominal fecal impaction was found only in DR group. Appendicostomy for antegrade continence enema was successful in 4/12 (30%) of SCT patients (median follow-up: 2.4 years). CONCLUSION Nuclear transit study distinguished two colonic dysmotility patterns and was useful for guiding refractory patients to specific therapies.

Abstract
BACKGROUND Defecography is a study to assess anorectal function during evacuation. OBJECTIVE To investigate the value of fluoroscopic defecography in directing diagnostic and therapeutic management in children with defecation disorders. MATERIALS AND METHODS We reviewed all fluoroscopic defecography studies performed (2003-2009) in children with defecation problems and normal anorectal motility studies. Results were classified into three groups: (1) normal pelvic floor function; (2) pelvic floor dyssynergia, including incomplete relaxation of pelvic musculature, inconsistent change in anorectal angle and incomplete voluntary evacuation; (3) structural abnormality, including excessive pelvic floor descent with an intra-rectal intussusception, rectocele or rectal prolapse. RESULTS We included 18 patients (13 boys, median age 9.1 years). Indication for fluoroscopic defecography was chronic constipation in 56%, fecal incontinence in 22% and rectal prolapse in 22%. Defecography showed pelvic floor dyssynergia in 9 children (50%), a structural abnormality in 4 (22%) and normal pelvic floor function in 5 (28%). In 12 children (67%) the outcome of fluoroscopic defecography directly influenced therapeutic management. After defecography 4 children (22%) were referred for anorectal biofeedback treatment, 4 children (22%) for surgery, 2 children (11%) for additional MR defecography, and 1 child to the psychology department, and medication was changed in 1 child. In 6 children (33%) the result did not change the management. In 9 children (75%) the change of management was successful. CONCLUSIONS Fluoroscopic defecography can be a useful tool in understanding the pathophysiology and it may provide information that impacts management of children with refractory defecation disorders.

Abstract
UNLABELLED On the basis of 15 years' of experience the criteria of assessment of the colon was developed when performing hydrocolonic echography (HCE) and the possibilities of HCE are evaluated at chronic constipations (CC) in children. A retrospective cross research of results of HCE in 263 children with CC aged from 14 days to 17 years was conducted. HCE allowed to evaluate the position of the colon in the abdominal cavity, gave information on lengthening and lumen of the colon, structure of the intestinal wall, haustra, peculiarities of the functioning of the colon in real time. Secondary changes of the colon due to CC, depending on intensity of CC are identified. Echographical characteristics of dolihocolon (light constipations) and dolihomegacolon (severe constipations) are given. Possibilities of echographical identification of the surgical provenance (diseases of Hirschsprung, Payr) of constipation in children are defined. CONCLUSION Hydrocolonic echography grants high possibilities of diagnostics and allows identifying the organic reason of constipation in due time. In case of functional constipation, HCE narrows down the amount of additional examinations. Identification of secondary changes of the colon due to CC does hydrocolonic echography by the instrument of quality control of conservative treatment with the advantage of HCE of lacking radiation and the possibility of unlimited replication.

Abstract
We herein report a case regarding a 90-year-old woman with a history of recurrent episodes of urinary tract infections presenting with fever. Urinalysis revealed bacteria and white blood cells. Computed tomography showed dilated and fecally loaded rectum and colon with signs of obstructive uropathy. The patient was treated for urinary tract infection and constipation. Her bowel habits were controlled with lubiprostone, and she was discharged in good medical condition. This case highlights the importance of considering fecal impaction as a cause of urinary tract obstruction or infection.

Abstract
Use of ultrasonic diagnostics reduces number of the low-informative, invasive and connected with beam loading procedures. Objectivity of results of ultrasonic structure of an intestinal wall depends on many subjective parameters: from the device on which examination, from the expert experience, from extent of preparation of intestines, from the applied solution for contrasting, from degree of expressiveness of a desire on a defecation is conducted when filling a thick gut.

Abstract
PURPOSE To evaluate the types of constipation according to colonic transit time in chronically constipated children with dysfunctional voiding (bowel bladder dysfunction, BBD group) and to compare the results with transit type in children with chronic functional constipation without urinary symptoms (constipation group) and children with normal bowel habits, but with lower urinary tract symptoms (control group). PATIENTS AND METHODS One-hundred and one children were included and their medical histories were obtained. The BBD group kept a voiding diary, and underwent urinalyses and urine culture, ultrasound examination of bladder and kidneys and uroflowmetry with pelvic floor electromyography. Radionuclear transit scintigraphy was performed in all children according to a standardized protocol. Patients were categorized as having either slow-transit (ST), functional fecal retention (FFR) or normal transit. RESULTS FFR was diagnosed in 31 out of 38 children with BBD, and 34 out of 43 children in the constipation group. ST was found in seven children with BBD, compared with nine children in the constipation group. The control group children demonstrated normal colonic transit. Urgency, daily urinary incontinence and nocturnal enuresis were noted only in children with FFR. Both children with ST constipation and FFR complained of difficulties during voiding, voiding postponement and urinary tract infections. CONCLUSIONS FFR is the most common form of constipation in children with dysfunctional voiding. However, some children might suffer from ST constipation. Differentiation between these two types of constipation is clinically significant because they require different treatment. Future studies with larger numbers of patients are needed to confirm the noted differences in urological symptoms in these two groups of constipated children..

Abstract
The aim of the study was to define the informative significance of USI in the diagnosis of functional and organic changes in patients suffering from chronic constipation (CC). 96 patients with CC were evaluated and treated. There were 67 women and 29 men (79) aged 33-55 years. 11 patients were in compensated stage of CC, 32 patients were in subcompensated stage, 53 patients-in decompensated stage of CC. Before investigation under USI control a colon was filled with 2 l of physiologic solution heated up to 37º. Sonographically in normotonic type of CC a colonic wall tonus was reserved, no changes in colonic transition were observed, while there is a delay in rectum. In subcompensated stage of atonic type of CC there was observed a noticeable enlargement of colonic diameter in transverse colon, descending colon and also in sigmoid colon. It is likely, that the wall of all portions of colon was thickened. The reduction of height of transverse folds and the increase of distance between them was traced in colon. In spastic type of CC a colonic wall tonus has been increased in all portions, there are spastic segments in colon, the distance of fecal particles' displacement from spastic region is enlarged. It is obviously that for atonic type of CC sonographically it is typical the attenuation of colonic wall tonus in all portions of colon, the reduction of distance of colonic content displacement and also the reduction of height of natural transverse folds and haustra fundus flattening.

Abstract
Chronic functional constipation is a common disorder in childhood. The treatment most often consists of the modalities education, disimpaction and maintenance. In a recent Cochrane review of maintenance treatment polyethylene glycol (PEG) seems to be superior to placebo and to other laxatives including lactulose. This conclusion is in line with practice at most paediatric departments in Denmark. Still, larger randomized controlled studies with the curing of constipation as the primary end point are needed.
