Review
INTRODUCTION
Toxic megacolon is a rare but life-threatening condition. Diagnosis is made when both systemic toxicity and an enlarged colon are present. We undertook a systematic review of the literature to provide a list of toxic megacolon findings on computed tomography (CT) imaging along with the prevalence rate for each finding.
METHODS
PubMed, Embase, and Cochrane library were searched. After eligibility screening and quality assessment, the reported CT findings of toxic megacolon with their respective prevalence rates were extracted from the included studies. Pooled prevalence rates were calculated for each finding using random-effects model and inverse variance method. I statistics were used to estimate the heterogeneity. All statistical analyses were performed using R software. P-values less than 0.05 were considered significant.
RESULTS
Database search yielded a total of 122 records. Only 2 of these studies were finally selected following two-step eligibility screening. Most common CT features of toxic megacolon and their pooled prevalence rates [95% CI] were: colonic distension (reported in 100% of patients), abnormal haustration 96% [0.75-0.99], peri-colonic fat stranding 87% [0.29-0.99], nodular pseudo polyps 76% [0.52-0.91], multilayered appearance of colonic wall 58% [0.38-0.76], and ascites 57% [0.21-0.87]. Other reported CT features: colonic wall thickening, pleural effusion, accordion sign, small bowel/gastric distension, and segmental colonic wall thinning.
CONCLUSION
and implication for practice: Colonic distension can be accompanied by 10 other findings in CT images of patients with toxic megacolon. Although these findings are not specific, toxic megacolon should be included in the list of differential diagnoses when these findings are present.

Meta-Analysis
BACKGROUND
The incidence of Hirschsprung disease (HSCR) is nearly 1/5000 and patients with HSCR are usually treated through surgical intervention. Hirschsprung disease-associated enterocolitis (HAEC) is a complication of HSCR with the highest morbidity and mortality in patients. The evidence on the risk factors for HAEC remains inconclusive to date.
METHODS
Four English databases and four Chinese databases were searched for relevant studies published until May 2022. The search retrieved 53 relevant studies. The retrieved studies were scored on the Newcastle-Ottawa Scale by three researchers. Revman 5.4 software was employed for data synthesis and analysis. Stata 16 software was employed for sensitivity analysis and bias analysis.
RESULTS
A total of 53 articles were retrieved from the database search, which included 10 012 cases of HSCR and 2310 cases of HAEC. The systematic analysis revealed anastomotic stenosis or fistula [ I2 =66%, risk ratio (RR)=1.90, 95% CI 1.34-2.68, P <0.001], preoperative enterocolitis ( I2 =55%, RR=2.07, 95% CI 1.71-2.51, P <0.001), preoperative malnutrition ( I2 =0%, RR=1.96, 95% CI 1.52-2.53, P <0.001), preoperative respiratory infection or pneumonia ( I2 =0%, RR=2.37, 95% CI 1.91-2.93, P <0.001), postoperative ileus ( I2 =17%, RR=2.41, 95% CI 2.02-2.87, P <0.001), length of ganglionless segment greater than 30 cm ( I2 =0%, RR=3.64, 95% CI 2.43-5.48, P <0.001), preoperative hypoproteinemia ( I2 =0%, RR=1.91, 95% CI 1.44-2.54, P <0.001), and Down syndrome ( I2 =29%, RR=1.65, 95% CI 1.32-2.07, P <0.001) as the risk factors for postoperative HAEC. Short-segment HSCR ( I2 =46%, RR=0.62, 95% CI 0.54-0.71, P <0.001) and transanal operation ( I2 =78%, RR=0.56, 95% CI 0.33-0.96, P =0.03) were revealed as the protective factors against postoperative HAEC. Preoperative malnutrition ( I2 =35 % , RR=5.33, 95% CI 2.68-10.60, P <0.001), preoperative hypoproteinemia ( I2 =20%, RR=4.17, 95% CI 1.91-9.12, P <0.001), preoperative enterocolitis ( I2 =45%, RR=3.51, 95% CI 2.54-4.84, P <0.001), and preoperative respiratory infection or pneumonia ( I2 =0%, RR=7.20, 95% CI 4.00-12.94, P <0.001) were revealed as the risk factors for recurrent HAEC, while short-segment HSCR ( I2 =0%, RR=0.40, 95% CI 0.21-0.76, P =0.005) was revealed as a protective factor against recurrent HAEC.
CONCLUSION
The present review delineated the multiple risk factors for HAEC, which could assist in preventing the development of HAEC.

Review
Chagas disease (CD) is a neglected protozoan infection caused by , which affects about 7 million people worldwide. There are two available drugs in therapeutics, however, they lack effectiveness for the chronic stage-characterized mainly by cardiac (i.e., cardiomyopathy) and digestive manifestations (i.e., megaesophagus, megacolon). Due to the involvement of the immuno-inflammatory pathways in the disease's progress, compounds exhibiting antioxidant and anti-inflammatory activity seem to be effective for controlling some clinical manifestations, mainly in the chronic phase. Resveratrol (RVT) and curcumin (CUR) are natural compounds with potent antioxidant and anti-inflammatory properties and their cardioprotective effect have been proposed to have benefits to treat CD. Such effects could decrease or block the progression of the disease's severity. The purpose of this systematic review is to analyze the effectiveness of RVT and CUR in animal and clinical research for the treatment of CD. The study was performed according to PRISMA guidelines and it was registered on PROSPERO (CDR42021293495). The results did not find any clinical study, and the animal research was analyzed according to the SYRCLES risk of bias tools and ARRIVE 2.0 guidelines. We found 9 eligible reports in this study. We also discuss the potential RVT and CUR derivatives for the treatment of CD as well.

Review
BACKGROUND
Some guidelines for management of Hirschsprung's disease (HSCR, HD) have been developed, but their quality is vague. This study will systematically assess the quality of guidelines and analyze the key recommendations and the best evidence for guidelines.
METHODS
Applicable guidelines were retrieved using a systematic search of databases. The Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool was used to assess the quality of the guidelines. Then, the recommendations and evidence for the included guidelines were extracted and compared.
RESULTS
A total of nine guidelines were included in this study, and only one had an overall standardized score of more than 60%, indicating that it is worthy of recommendation. The problems identified included ambiguous and low-quality evidence; obvious distributional heterogeneity among the recommendations; a lack of in-depth discussion on the interpretation of staging, diagnostic methods, conservative treatment, and surgical staging of disease.
CONCLUSION
The quality of guidelines varies widely, and there is a lack of high-quality professional opinions and supporting evidence for the main recommendations. At present, only comprehensive guidelines can be considered high-quality and there is still room for improvement.

Review
BACKGROUND
Hirschsprung disease is commonly encountered by pediatric surgeons. Despite advances in the surgical management, these children may experience symptoms of bowel dysfunction throughout adulthood. Anorectal manometry may be used to assess post-operative anorectal structure and function. This review aimed to consolidate and evaluate the literature pertaining to post-operative findings of anorectal manometry in children with Hirschsprung disease.
PURPOSE
(1) Synthesize the available data regarding anorectal motility patterns in children following repair of Hirschsprung disease. (2) Evaluate the reported anorectal manometry protocols.
DATA SOURCES
We performed a systematic review of four databases: Embase, MEDLINE, the Cochrane Library, and PubMed.
STUDY SELECTION
This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies reporting results of post-operative anorectal manometry in children with Hirschsprung disease were evaluated for inclusion.
RESULTS
Twenty-three studies satisfied inclusion criteria, with a combined cohort of 939 patients. Post-operative anorectal manometry results were reported for 682 children. The majority of included studies were assessed as "poor quality." Disparate manometry protocols, heterogeneous cohorts, and lack of standardized outcome assessments introduced a risk of outcome reporting bias, limited the comparability of results, and impeded clinical translation of findings.
CONCLUSIONS
This systematic review demonstrated the lack of high-quality evidence underlying the current understanding of post-operative anorectal motility in children with HD. There was little consistency in reported manometry outcomes between studies. In future work, emphasis must be placed on the application of standardized manometry protocols, cohort reporting, and patient outcome assessments.

Review
is a gram-positive, anaerobic, spore-forming bacterium that produces toxins A and B, disrupting the intestinal brush border and resulting in severe diarrhea. The most common causes of infection include prolonged antibiotic use, proton pump inhibitors (PPIs), and long-term hospitalization resulting in complications such as pseudomembranous colitis and toxic megacolon. This systematic review aims to consider fecal microbiota transplantation (FMT) as an early treatment modality in infection to prevent complications and reduce related morbidity and mortality. We systematically screened three databases using regular keywords such as "fecal microbiota transplantation," "," "pseudomembranous colitis," and "toxic megacolon" and Medical Subject Headings (MeSH) terms. We applied the inclusion and exclusion criteria and performed a thorough quality appraisal using standardized checklists. We were finally left with 10 articles, including seven case reports, one case series, and two observational studies. Questions remain as to the route of administration of FMT, timing, safety, availability, and the number of sittings required. More randomized controlled trials are needed to address all these questions and to assess the safety of FMT. We believe the role of FMT is very important as it can prevent related complications and would be an ideal treatment option in a population group that is often unfit for surgical management.

Balkan Medical Journal Jan 2021Hirschsprung's disease and sigmoid volvulus can sometimes be seen in the same patient.
BACKGROUND
Hirschsprung's disease and sigmoid volvulus can sometimes be seen in the same patient.
AIMS
To investigate the presence of Hirschsprung's disease in patients with sigmoid volvulus and to discuss the diagnosis and treatment methods.
STUDY DESIGN
Systematic review.
METHODS
This systematic review has been reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the methodological quality of systematic reviews guidelines. The PubMed and Scopus databases were scanned using the keywords "Hirschsprung* volvulus*" and "congenital aganglionic megacolon volvulus*". The reference list of the selected studies was reviewed for cross-checking. Two reviewers independently screened the available literature. Only the Hirschsprung's disease cases involving sigmoid volvulus were included, and cases of patients with volvulus in other sites was excluded. There was no restriction with respect to the publication language and type of writing. The primary outcome was morbidity and mortality.
RESULTS
A total of 31 cases were analyzed in 22 articles; 97% of the patients were under the age of 40, 90% were male. There was a statistically significant difference in the necessity for relaparotomy between patients who were scheduled for sigmoid volvulus therapy with the suspicion of Hirschsprung's disease and patients who were treated without suspicion of Hirschsprung's disease (0% vs 37.5%, p=0.02). While there was no postoperative death in cases with suspected Hirschsprung disease, this mortality rate was 25% in cases without suspicion (p = 0.08).
CONCLUSION
Hirschsprung's disease should be excluded with rectal biopsy if a patient with sigmoid volvulus is under 40 years of age and has complaints of constipation from childhood.

BACKGROUND
In patients with ulcerative colitis or familial adenomatous polyposis who develop neoplasia or fail medical therapy and require colectomy, restorative proctocolectomy with IPAA is often indicated. Although often well tolerated, IPAA can be complicated by cuffitis or inflammation of the remaining rectal cuff. Although much has been published on this subject, there is no clear and comprehensive synthesis of the literature regarding cuffitis.
METHODS
Our systematic literature review analyzes 34 articles to assess the frequency, cause, pathogenesis, diagnosis, classification, complications, and treatment of cuffitis.
RESULTS
Cuffitis occurs in an estimated 10.2% to 30.1% of pouch patients. Purported risk factors include rectal cuff length >2 cm, pouch-rectal anastomosis, stapled anastomosis, J-pouch configuration, 2- or 3-stage IPAA, preoperative Clostridium difficile infection, toxic megacolon, fulminant colitis, preoperative biologic use, medically refractory disease, immunomodulator/steroids use within 3 months of surgery, extraintestinal manifestations of IBD, and BMI <18.5 kg/m2 at the time of colectomy. Adverse consequences associated with cuffitis include decreased quality-of-life scores, increased risk for pouchitis, pouch failure, pouch excision, and pouch neoplasia.
CONCLUSIONS
Given the similarities between pouchitis and cuffitis, diagnosis and treatment of cuffitis should proceed according to the International Ileal Pouch Consortium guidelines. This review found that the majority of the current literature fails to distinguish between classic cuffitis (a form of reminant ulcerative proctitis) and nonclassic cuffitis (resulting from other causes). Further work is needed to distinguish the unique risk factors and endoscopic characteristics associated with each subtype, and further randomized clinical trials should be conducted to strengthen the evidence for treatment options.

PURPOSE
Hirschsprung's associated enterocolitis (HAEC) is a complication of Hirschsprung's Disease (HD) with considerable morbidity and mortality. The variability in presentation leads to a wide variety of the reported prevalence pre-and postoperatively. This systematic review aimed to clarify the prevalence of HAEC in short-(S-HD), long (L-HD), TCA and the type of operation used.
METHODS
A systematic literature-based search for relevant cohorts was performed using Pubmed/Medline, Cochrane Library from its inception to May 2021. Studies reporting on pre-and postoperative enterocolitis, segment length, and surgical procedure (Soave, Swenson, Duhamel) were included. Pooled prevalence and subgroup analysis have been calculated for pre-and postoperative HAEC.
RESULTS
4738 articles were identified from the literature search, among which 57 studies, including 9744 preoperative and 8568 postoperative patients, were included. The groups were sorted by length of the aganglionic segment for further analysis. The pooled prevalence for preoperative HAEC was 18.3% for all types, 15.2% for S-HD and 26.1% for TCA. The pooled prevalence for postoperative HAEC was in total 18.2% for all segment lengths and used techniques. Subgroup analysis showed no significant difference in the occurrence of postoperative enterocolitis between the three techniques.
CONCLUSION
The prevalence of preoperative HAEC increases with segment length. However, pooled data suggest that the postoperative risk for developing HAEC, independently of the employed method and segment length, is comparable to the preoperative risk.

Meta-Analysis
BACKGROUND
Patients with Hirschsprung disease (HD) are at risk of persistent constipation, fecal incontinence or recurrent enterocolitis after surgical treatment, which in turn may impact physical and psychosocial functioning. Generic health-related quality of life (HRQoL) and disease-specific health-related quality of life are relevant outcome measures to assess the impact of HD on the QoL of these patients.
AIM
To summarize all available evidence on HRQoL of patients with HD after surgery and the impact of possible moderating factors.
METHODS
Pubmed, Web of Sciences, PsycInfo and Embase were searched with search terms related to 'Hirschsprung disease', 'Pediatrics' and 'Quality of life'. Mean and standard deviation of generic HRQoL overall and domain scores were extracted from each study, as well as data describing potential factors associated with QoL. Random effect models were used for meta-analytic aggregation of generic HRQoL scores. Meta-regression was used to assess the relationship between patient and clinical characteristics and generic HRQoL. Disease-specific HRQoL outcomes of patients with HD were systematically reviewed.
RESULTS
Seventeen articles were included in the systematic review ( = 1137 patients) and 15 in the quantitative meta-analysis ( = 1024 patients). Four studies reported disease-specific HRQoL. Patient's age ranged between 0 and 21 years. Meta-analytic aggregation showed a non-significantly impaired generic HRQoL ( = -0.168 [95%CI: -0.481; 0.145], = 0.293, = 94.9) in patients with HD compared to healthy controls. Physical ( = -0.042 [95%CI: -0.419; 0.335], = 0.829, = 95.1), psychosocial ( = -0.159 [95%CI: -0.458; 0.141], = 0.299, = 93.6) and social HRQoL ( = -0.092 [95%CI: -0.642; 0.457], = 0.742, = 92.3) were also not significantly lower compared to healthy controls. There was no relation between health-related outcomes and the sex of the patients and whether generic HRQoL was measured by parental proxy or self-report. Disease-specific complaints of patients with HD impaired physical HRQoL, but not psychosocial and social HRQoL.
CONCLUSION
In this systematic review and meta-analysis, no evidence was found for impaired generic HRQoL in patients with HD compared to healthy controls, neither for moderating effects of sex, parental proxy or self-report.
