Review
INTRODUCTION
infection (CDI) is a clinical and laboratory diagnosis. Populations at higher risk of developing disease require a high clinical index of suspicion for laboratory testing to avoid incorrect assumptions of colonization. Common risk factors include recent antibiotic use, elderly (>65 years old), and immunocompromised patients. ssays should be ordered in an algorithm approach to diagnose an infection rather than colonization. Screening tests are widely available in hospital systems, but novel molecular testing may aid in diagnosis in patients with inconclusive or discordant antigen and toxin test results. Methods: Data was extracted from PubMed, Scopus, and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases based on the keywords "", "toxin assay", and "toxic megacolon". The data extracted is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. A total of 27 reports were included in this systematic review.
RESULTS
Testing patients with a significant gastrointestinal surgical history, hypogammaglobulinemia, inflammatory bowel disease, intensive care unit, and immunocompromised patients for CDI is highly recommended. Diarrhea in these subsets of patients requires correlation of clinical context and an understanding of assay results to avoid over- and under-treating.
CONCLUSION
CDI should be considered in all patients with traditional risk factors. Heightened clinical suspicion of CDI is required in patients with hypogammaglobulinemia, transplant recipients, patients with gastrointestinal surgical history, and inflammatory bowel disease. Testing should be limited to patients with clinical manifestations of CDI to ensure a high pretest probability for test interpretation. Healthcare workers should adhere to testing algorithms to optimize yield in the appropriate clinical context. Diagnostic assays should follow a sequential, stepwise approach to categorize the toxin expression status of the bacteria accurately.

BACKGROUND/PURPOSE
Hirschsprung's disease (HSCR) and anorectal malformation (ARM) are often associated with other congenital malformations, but the association of each other is rare. Some studies have reported the incidence of HSCR associated with ARM ranging from 2.0 to 3.4%. The purpose of this study was to update the current epidemiological and therapeutic features of this rare congenital association.
METHODS
A systematic literature search for relevant articles was performed in four databases using a combination of the following terms "association of Hirschsprung's disease and anorectal malformation", "aganglionosis and anorectal malformation" and "congenital megacolon and anorectal malformation" for studies published between 1952 and 2019. Reference lists were screened for additional cases.
RESULTS
Forty-three studies met the defined inclusion criteria, reporting a total of 126 patients who were diagnosed with HSCR with ARM. Thirty articles reported 42 single case reports of this association. Twelve articles reported 66 cases of HSCR in case series of 3309 ARM patients, resulting in an incidence of 2% of this association. Associated syndrome was found in 25 cases (20%): Currarino syndrome in 11, Down syndrome in 8, Cat eye syndrome in 4 and Pallister-Hall syndrome in 2 patients. Extent of aganglionosis was reported in 62 cases: short or rectosigmoid aganglionosis was reported in 44, long segment aganglionosis in 8, total colonic aganglionosis in 9 and total intestinal aganglionosis in 1 case.
CONCLUSION
Although the association of ARM and HSCR is rare, the incidence of HSCR among ARM cases seems to be higher than in the general pediatric population. There was a high incidence of coexistence of ARM and HSCR with severe associated syndromes.

INTRODUCTION
Enemas containing phosphate are widely prescribed and may cause important adverse effects. A systemic review published in 2007 reported the literature on the adverse effects of phosphate enemas from January 1957 to March 2007 and identified 12 deaths. These were thought due to electrolyte disturbances, heart failure and kidney injury. These data raised concerns about the use of phosphate enemas in routine practice. Newer osmotic-based enema alternatives are now available that do not contain absorbable ions. We sought to review the literature since this review and evaluate the latest data on the toxicity of phosphate-containing enemas. To gain a fuller picture we included case series and larger studies as well as case reports.
OBJECTIVES
To review the toxicity of phosphate enemas, particularly with respect to acute metabolic consequences and their associated clinical features. To identify risk factors for metabolic toxicity and consider whether phosphate enemas should be relatively contra-indicated in specific patient groups.
METHODS
A systematic literature review was conducted in PubMed, Google Scholar, and Cochrane Reviews (2005-2021) using the search terms 'phosphate enema or sodium phosphate enema' or 'phosphate-based enema' or (phosphate AND enema) or (Fleet AND enema) or 'sodium phosphate laxatives' or 'sodium phosphate catharsis' or 'sodium phosphate cathartic'. Relevant papers were read, and data were extracted.
RESULTS
The searches identified 489 papers of which 25 were relevant: seven papers were case reports or small case series of metabolic abnormalities from the use of phosphate enemas in nine children, six were case reports on 16 adults. Nine papers were large case series or clinical studies that included data on systemic metabolic effects, of varying size from 24 healthy volunteers to a cohort of 70,499 patients. Case reports identified seven adult deaths but none in children. Children most often presented with decreased consciousness (6/9), and tetany (4/9). In adults overall only five cases had clinical features reported, hypotension was seen in four and QT prolongation in two. Treatment was generally symptomatic, with intravenous fluid and calcium salts for electrolyte changes and hypocalcaemia, and vasopressors for severe hypotension. Haemodialysis was used in three children and peritoneal dialysis in one, all of whom survived. In adults, haemodialysis did not prevent death in two of four cases in whom it was used. Common factors underlying toxicity were inappropriately high phosphate dose, or enema retention, both resulting in greater absorption of phosphate. Associated pre-disposing conditions included Hirschsprung disease in children and co-morbidity and renal impairment (2/5) in older adults. Absolute reported changes in serum phosphate or calcium were not accurate indicators of outcome. Larger case series and clinical trials confirm an acute effect of phosphate enemas on serum phosphate, which was related to both dose and retention time. These effects were not seen with non-phosphate preparations. In these cases series, adverse events were rarely reported.
CONCLUSION
Phosphate enemas are potentially toxic, particularly in young children with Hirschsprung disease and in the elderly with co-morbidity. Raised awareness of the risk of phosphate enemas is still required. Other less toxic enema preparations are available and should be considered in patients at extremes of age. If phosphate enemas are the only clinical option careful monitoring of biochemical sequelae should be undertaken.

Review
BACKGROUND
Colonic pseudo-obstruction (CPO) is characterized by colonic distention in the absence of mechanical obstruction or toxic megacolon. Concomitant secretory diarrhea (SD) with hypokalemia (SD-CPO) due to gastrointestinal (GI) loss requires further characterization.
AIM
To perform a systematic review of SD-CPO, report a case study, and compare SD-CPO with classical CPO (C-CPO).
METHODS
We performed a search of MEDLINE, EMBASE, Cochrane, and Scopus for reports based on a priori criteria for CPO, SD and GI loss of potassium. An additional case at Mayo Clinic was included.
RESULTS
Nine publications met inclusion criteria, with a total of 14 cases. Six studies had high, three moderate, and our case high methodological quality. Median age was 74 years (66-97), with 2:1 male/female ratio. Kidney disease was present in 6/14 patients. Diarrhea was described as profuse, watery, or viscous in 10 patients. Median serum, stool, and urine potassium concentrations (mmol/L) were 2.4 (range: 1.9-3.1), 137 (100-180), and 17 (8-40), respectively. Maximal diameter of colon and cecum (median) were 10.2 cm and 10.5 cm, respectively. Conservative therapy alone was effective in five out of 14 patients. Median potassium supplementation was 124 mEq/d (40-300). Colonic decompression was effective in three out of six patients; one had a total colectomy; three out of 14 had died. The main differences between SD-CPO and C-CPO were lower responses to treatments: conservative measures (35.7% vs 73.6%, P=.01), neostigmine (17% vs 89.2%, P<.001), and colonic decompression (50% vs 82.4%, P=.02).
CONCLUSION
SD-CPO is a rare phenotype associated with increased fecal potassium and is more difficult to treat than C-CPO.

Review
Heterogeneity in outcome reporting limits identification of gold-standard treatments for Hirschsprung's Disease(HD) and gastroschisis. This review aimed to identify which outcomes are currently investigated in HD and gastroschisis research so as to counter this heterogeneity through informing development of a core outcome set(COS). Two systematic reviews were conducted. Studies were eligible for inclusion if they compared surgical interventions for primary treatment of HD in review one, and gastroschisis in review two. Studies available only as abstracts were excluded from analysis of reporting transparency. Thirty-five HD studies were eligible for inclusion in the review, and 74 unique outcomes were investigated. The most commonly investigated was faecal incontinence (32 studies, 91%). Seven of the 28 assessed studies (25%) met all criteria for transparent outcome reporting. Thirty gastroschisis studies were eligible for inclusion in the review, and 62 unique outcomes were investigated. The most commonly investigated was length of stay (24 studies, 80%). None of the assessed studies met all criteria for transparent outcome reporting. This review demonstrates that heterogeneity in outcome reporting and a significant risk of reporting bias exist in HD and gastroschisis research. Development of a COS could counter these problems, and the outcome lists developed from this review could be used in that process.

Meta-Analysis Review
AIM AND OBJECTIVES
Hirschsprung-associated enterocolitis (HAEC) continues to be an important cause of morbidity in patients with Hirschsprung's disease (HSCR). HAEC can occur at any time during the course of the disease. The reported incidence of HAEC before surgery ranges from 6 to 50%, and after surgery, it ranges from 2 to 35%. HAEC and inflammatory bowel disease (IBD) have similar clinical presentation including diarrhea, hematochezia, and abdominal pain. In recent years, isolated cases of IBD have been reported in patients who had surgical treatment for HSCR. The exact pathogenesis of HAEC or IBD is not known. However, both conditions are characterized by an abnormal intestinal mucosal barrier function, which may be a common pathway. The purpose of this meta-analysis was to determine the clinical presentation and outcome in patients with HSCR who developed IBD after pull-through operation.
MATERIALS AND METHODS
A systematic literature search for relevant articles was performed in four databases using the combinations of the following terms "inflammatory bowel disease", "Crohn/Crohn's disease", "ulcerative colitis", and "Hirschsprung disease/Hirschsprung's disease" for studies published between 1990 and 2017. The relevant cohorts of HSCR associated with IBD were systematically searched for clinical presentation and outcomes.
RESULTS
14 studies met defined inclusion criteria, reporting a total of 66 patients who had HSCR associated with IBD. Mean age at first operation for HSCR was 5.8 months, mean age at diagnosis of IBD was 7.7 years, and the majority of patients were male (73%). The extent of aganglionosis was total colonic aganglionosis in 41% of patients, long segment in 45%, and rectosigmoid in 14%. The majority of patients underwent a Duhamel procedure (84%) for HSCR. The distribution of IBD was Crohn's disease in 72.3% of patients, ulcerative colitis in 16.9%, and others in 10.8%. Eight articles (47 patients) reported about HAEC, and 22 patients (47%) had experienced HAEC after surgery for HSCR.
CONCLUSION
Male patients with extensive colonic aganglionosis who continue to suffer from postoperative HAEC after a Duhamel procedure are more susceptible to develop IBD. Recognition of IBD may be important in the long-term follow-up of HSCR patients who have had postoperative HAEC.

Review
PURPOSE
Intestinal dysmotility in preterm infants has often been attributed to immature enteric nervous system. It is frequently reported that Hirschsprung's disease (HD) is rare in premature infants. The exact prevalence of HD in premature infants is not well documented. The classical signs of HD may often not be identified due to the complexity of symptoms of prematurity itself. This systematic review was designed to determine the prevalence and presentation of HD in premature infants.
METHODS
A systematic review of the literature using the keywords "Hirschsprung's disease", "aganglionosis", "congenital megacolon", "premature" and "preterm" was performed. Resulting publications were reviewed for epidemiology and morbidity. Only infants born <37 weeks of gestation or described as preterm birth by the authors were included. Reference lists were screened for additional relevant studies.
RESULTS
Twenty-six publications from 1964 to 2013 reported data on premature infants with HD. Out of a total number of 4,147 infants, prematurity was recorded in 257 cases, giving a prevalence rate of 6 % of preterm infants diagnosed with HD. During 1964-1999, reported prevalence of HD in premature infants ranged from 1.7 to 9.2 % (overall prevalence 5 %) and during 2000-2013 prevalence ranged from 4 to 19.4 % (overall prevalence 14 %). The prevalence of total colonic aganglionosis in premature infants was 13 % (15 out of 118 infants). Mean gestational age of preterm infants was 34.5 (± 0.7) weeks and mean age at diagnosis ranged from 18.3 days to 3.9 months. Abdominal distension was observed in 80 % of preterm infants, delayed passage of meconium in 57 and 37 % of premature infants presented with bile-stained vomiting.
CONCLUSION
In recent years, higher prevalence of HD has been reported in premature infants compared to previous years. Hirschsprung's disease should be considered in preterm infants presenting with features of intestinal obstruction.

Review
PURPOSE
Congenital anomalies of the kidney and urinary tract (CAKUT), a term introduced in the late 1990 s accounts for 30-50 % of cases of end-stage renal disease in children. The association of urogenital anomalies and Hirschsprung's disease (HSCR) based on the common genetic background of enteric nervous system and human urinary tract development has been well described in the literature. However, the reported prevalence of HSCR associated with CAKUT seems to be underestimated. The aim of this systematic review was to determine the prevalence of this association and show its relationship to other syndromes.
METHODS
A systematic literature search was conducted for relevant articles published between 1955 and 2014. Two online databases were searched for the terms "Hirschsprung's disease", "congenital anomalies of the kidney and urinary tract", "urogenital anomalies" and "urological anomalies". All published studies containing adequate clinical data were included. Resulting publications were reviewed for epidemiology, genetic testing, operative treatment and morbidity. Reference lists were screened for additional cases.
RESULTS
A total of 32 articles reported 222 cases of HSCR associated with either CAKUT, "urological" or "urogenital" anomalies from 1955 to 2014. Gender was reported in a total of 68 cases, with 54 (79 %) males and 14 (21 %) females. Extent of aganglionosis was reported in 67 cases and included classical rectosigmoid disease in 38, long-segment aganglionosis in 12, total colonic aganglionosis in 12 and total intestinal aganglionosis in 5 patients. 18 articles reported 204 cases of either CAKUT, "urological" or "urogenital" anomalies in a case series of 5.693 HSCR patients, resulting in an overall prevalence of 3.6 % of this association. Within this collective of 18 studies only seven were, regardless of the date of publication compatible with CAKUT criteria introduced and published in the late 1990 s. These seven studies reported a total of 72 patients with associated CAKUT among 757 HSCR patients resulting in a prevalence of 9.5 %. After introduction of the CAKUT acronym, only three studies specifically investigated the association of HSCR and CAKUT stating a prevalence of 14.3 % resulting in an almost fivefold increase compared to the reported prevalence of HSCR and associated urological and urogenital anomalies. The remaining 14 publications reported 18 single cases of HSCR patients with associated CAKUT phenotypes. Of these 18 cases, 11 (61 %) cases were associated with other syndromes or syndromatic features or reported chromosomal anomalies.
CONCLUSION
This review confirms that the recognition of CAKUT in HSCR patients has been underestimated in the past. The results suggest that when confronted with HSCR in a patient, a thorough urological investigation may be indicated. The high prevalence of associated syndromes in HSCR with CAKUT may further suggest a syndromic association.

Review
PURPOSE
In the last two decades, laparoscopic-assisted pull-through (LAPT) has gained much popularity in the treatment of Hirschsprung's disease. The aim of this meta-analysis was to determine the long-term outcome of patients treated laparoscopically.
METHODS
A systematic literature-based search for relevant cohorts was performed using the terms "Hirschsprung's disease and Laparoscopy", "Laparoscopic-assisted pull-through outcome", "Laparoscopic-assisted Soave pull-through" "Laparoscopic-assisted Swenson pull-through" and Laparoscopic-assisted Duhamel pull-through. The relevant cohorts of laparoscopic operated HD were systematically searched for outcome regarding continence, constipation, secondary surgery related to the laparoscopic approach and enterocolitis. Pooled incidence rates and odds ratios (ORs) with 95 % confidence intervals (CI) were calculated using standardized statistical methodology.
RESULTS
Sixteen studies met defined inclusion criteria, reporting a total of 820 patients. All studies were retrospective case series, with variability in outcome assessment quality and length of follow-up. The median cohort size consisted of 28 patients (range 15-218). In the long-term follow-up, 97 patients (11.14 %) experienced constipation (OR 0.06, 95 % CI 0.05-0.08, p < 0.00001), 53 (6.46 %) incontinence/soiling (OR 0.01 95 % CI 0.01-0.01, p < 0.00001), 75 (9.14 %) recurrent enterocolitis (OR 0.02 95 % CI 0.01-0.02, p < 0.00001) and 69 (8.4 %) developed complications requiring secondary surgery (OR 0.01 95 % CI 0.01-0.02, p < 0.00001). Overall events in long-term follow-up occurred in 225 (27.5 %) patients (OR 0.24 95 % CI 0.20-0.30, p < 0.00001).
CONCLUSIONS
This meta-analysis shows that nearly one-third of the patients continue to have long-term bowel problems, such as constipation, soiling and recurrent enterocolitis following LAPT. Many patients treated by LAPT require secondary surgery. Large randomized studies with long-term follow-up are necessary to determine the difference in outcome between LAPT and completely transanal pull-through operation.

Review
PURPOSE
Hirschsprung's disease (HD) occurs as an isolated phenotype in 70% of infants and is associated with additional congenital anomalies or syndromes in approximately 30% of patients. The cardiac development depends on neural crest cell proliferation and is closely related to the formation of the enteric nervous system. HD associated with congenital heart disease (CHD) has been reported in 5-8% of cases, with septation defects being the most frequently recorded abnormalities. However, the prevalence of HD associated with CHD in infants with syndromic disorders is not well documented. This systematic review was designed to determine the prevalence of CHD in syndromic HD.
METHODS
A systematic review of the literature using the keywords "Hirschsprung's disease", "aganglionosis", "congenital megacolon", "congenital heart disease" and "congenital heart defect" was performed. Resulting publications were reviewed for epidemiology and morbidity. Reference lists were screened for additional relevant studies.
RESULTS
A total of fifty-two publications from 1963 to 2014 reported data on infants with HD associated with CHD. The overall reported prevalence of HD associated with CHD in infants without chromosomal disorders was 3%. In infants with syndromic disorders, the overall prevalence of HD associated with CHD ranged from 20 to 80 % (overall prevalence 51%). Septation defects were recorded in 57% (atrial septal defects in 29%, ventricular septal defects in 32%), a patent ductus arteriosus in 39%, vascular abnormalities in 16%, valvular heart defects in 4% and Tetralogy of Fallot in 7%.
CONCLUSION
The prevalence of HD associated with CHD is much higher in infants with chromosomal disorders compared to infants without associated syndromes. A routine echocardiogram should be performed in all infants with syndromic HD to exclude cardiac abnormalities.
