UNASSIGNED: Chronic constipation is a common condition in pediatric patients worldwide and is associated with decreased quality of life. Inpatient management of constipation is required when outpatient therapy fails and a child becomes obstipated, and unable to pass stool or gas. There is a growing body of evidence regarding different management strategies for pediatric obstipation. This scoping review aims to map the existing literature regarding inpatient management of pediatric obstipation and identify gaps in knowledge.
UNASSIGNED: We will follow the methodology described by the Joanna Briggs Institute and outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. The search strategy will include Embase, PubMed, CINAHL, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, Scopus, and gray literature sources. Two independent reviewers will complete screening for eligible studies in two steps: a scan of the title and abstracts followed by a full-text review. Studies regarding inpatient management of pediatric obstipation, with experimental or cohort design, and with full text available in English will be included. Systematic reviews will also be included. Two independent reviewers will extract data using a standardized form. Extracted data will be presented in visual and narrative formats, including an evidence map to meet the objectives of this scoping review. This protocol is registered at Open Science Framework.
UNASSIGNED: In this scoping review, we will outline the current evidence available regarding the efficacy and safety of various hospital interventions for the treatment of pediatric obstipation.

OBJECTIVE: We conducted a comprehensive meta-analysis to compare the effectiveness and safety of fluoroscopy-guided air enema reduction (FGAR) and ultrasound-guided hydrostatic enema reduction (UGHR) for the treatment of intussusception in pediatric patients.
METHODS: A systematic review and meta-analysis were conducted on retrospective studies obtained from various databases, including PUBMED, MEDLINE, Cochrane, Google Scholar, China National Knowledge Infrastructure (CNKI), WanFang, and VIP Database. The search included publications from January 1, 2003, to March 31, 2023, with the last search done on Jan 15, 2023.
RESULTS: We included 49 randomized controlled studies and retrospective cohort studies involving a total of 9,391 patients, with 4,841 in the UGHR and 4,550 in the FGAR. Specifically, UGHR exhibited a significantly shorter time to reduction (WMD = -4.183, 95% CI = (-5.402, -2.964), P < 0.001), a higher rate of successful reduction (RR = 1.128, 95% CI = (1.099, 1.157), P < 0.001), and a reduced length of hospital stay (WMD = -1.215, 95% CI = (-1.58, -0.85), P < 0.001). Furthermore, UGHR repositioning was associated with a diminished overall complication rate (RR = 0.296, 95% CI = (0.225, 0.389), P < 0.001) and a lowered incidence of perforation (RR = 0.405, 95% CI = (0.244, 0.670), P < 0.001).
CONCLUSIONS: UGHR offers the benefits of being non-radioactive, achieving a shorter reduction time, demonstrating a higher success rate in repositioning in particular, resulting in a reduced length of postoperative hospital stay, and yielding a lower overall incidence of postoperative complications, including a reduced risk of associated perforations.

Intussusception (ISN) is a dangerous condition where a portion of the intestine slides into an adjacent area of the intestine. This telescoping motion frequently prevents liquids or food from flowing through. Developing management guidelines for ileocolic (IC) intussusception was the aim of this systematic study. Data sources were PubMed/Medical Literature Analysis and Retrieval System Online (MEDLINE), Scopus, and Embase databases. Our review investigated English-language articles (from 2010 to 2023) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Overall, there were 15 articles. Surveys and analyses of national databases were the most widely used methods (n=15). The search identified 561 studies; 15 were eligible for inclusion in the analysis. Further understanding of the management of intussusception may help improve evaluation and management in the future. The use of preventive antibiotics does not reduce problems following radiologic reduction. When clinically appropriate, repeated attempts at enema reduction may be made. After the enema reduction of ileocolic intussusception, patients can be safely watched in the emergency room (ER), thereby avoiding hospitalization. Success rates for laparoscopic reduction are high. When it comes to intussusception in children who are hemodynamically stable and do not have a serious illness, there is no need for pre-reduction antibiotics. Prioritizing nonoperative outpatient (OP) therapy is recommended as the primary approach, with the utilization of minimally invasive procedures to avoid the necessity for laparotomy. The management of colonic intussusception involves complete removal in one piece, while enteric intussusception can be addressed through reduction followed by resection. A targeted approach is recommended, recognizing the intermediate forms of intussusception that may exist between the colonic and enteric types. It is essential to note that the prevailing treatment for adult intussusception remains to be surgical intervention.

BACKGROUND: In children with ileocolic intussusception, sedatives such as midazolam, ketamine and propofol may facilitate radiologic enema reduction, but studies on their separate and joint effects remain controversial.
OBJECTIVE: We aimed to systematically analyze studies for the effects of sedatives on the radiologic reduction of ileocolic intussusception in children.
METHODS: We searched PubMed, EMBASE, CINAHL, Scopus and Web of Science from database inception through March 2023 for articles that enrolled children with ileocolic intussusception who underwent non-operative pneumatic or hydrostatic enema reduction under ultrasound or fluoroscopic guidance with or without the use of sedatives. The primary and secondary outcomes were success rate in radiologic reduction of ileocolic intussusception and risk of perforation, respectively. Effect estimates from the individual studies were extracted and combined using the Hartung-Knapp-Sidik-Jonkman log-odds random-effects model. Heterogeneity between studies was checked using Cochran\'s Q test and the I2 statistic.
RESULTS: A total of 17 studies with 2094 participants were included in the final review, of which 15 were included in the meta-analysis. Nine studies reported on the success rate of radiologic reduction performed under sedation in all participants, while six studies compared the success rate in two patient groups undergoing the procedure with or without sedation. The pooled success rate of non-operative reduction under sedation was 87 % (95 % CI: 80-95 %), P = 0.000 with considerable heterogeneity (I2 = 85 %). A higher success rate of 94 % (95 % CI: 88-99 %) and homogeneity (I2 = 12 %) were found in studies with pneumatic enema reduction. Among comparative studies, the odds of success of non-operative reduction were increased when the procedure was performed under sedation, with a pooled odds ratio of 2.41 (95 % CI: 1.27-4.57), P = 0.010 and moderate heterogeneity (I2 = 60 %). In a sensitivity analysis, homogeneity was found between analyzed studies when two outliers were excluded (I2 = 0.73 %). The risk of perforation was not significantly different (OR 1.52, 95 % CI: 0.09-23.34), P = 0.764 indicating small study effects. No publication, bias was detected on visual inspection of the funnel plots or the Begg\'s and Egger\'s bias tests. Most studies were categorized as having a low risk of bias using Joanna Briggs Institute checklists.
CONCLUSIONS: In selected patient groups, sedation can increase the success rate of radiologic enema reduction in children with ileocolic intussusception without evidence of increased risk of perforation. Systematic review protocol registration: PROSPERO CRD42023404887.

Chinese medicinal retention enemas have gradually attracted the attention of clinicians as an alternative approach for tubal obstructive infertility. The purpose of this study was to investigate the efficacy and safety of conventional surgery combined with traditional Chinese medicinal retention enemas for the treatment of tubal obstructive infertility.
Eight electronic databases were searched from their inception to November 30, 2022. To assess the efficacy and safety of different treatments, following outcomes were measured: clinical pregnancy rate, clinical total effective rate, incidence of ectopic pregnancy, the improvement of Traditional Chinese Medicinal (TCM) symptoms, the improvement of the signs of obstructive tubal infertility and side effects.
A total of 23 Randomized Controlled Trials (RCTs) with 1909 patients met the inclusion criteria. The pooled results showed a higher pregnancy rate in the experimental group than in the control group (RR 1.75, 95% CI [1.58, 1.94], Z = 10.55, P<0.00001). The clinical total effective rate in the experimental group was higher than that in the control group (RR 1.28, 95% CI [1.23, 1.34], Z = 11.07, P<0.00001). The incidence of ectopic pregnancy in the experimental group was lower than that in the control group (RR 0.40, 95% CI [0.20, 0.77], Z = -2.73, P = 0.01).
Based on current evidence, we concluded that conventional surgery combined with traditional Chinese medicinal retention enema for tubal obstructive infertility was superior to conventional surgery alone in improving the clinical pregnancy rate, improving clinical total effective rate, improving TCM symptoms, improving the signs of obstructive tubal infertility and lowering the incidence of ectopic pregnancy. However, further clinical trials with high-quality methodologies need to be conducted.

Constipation is common in the pediatric population and in severe forms it can lead to debilitating fecal incontinence which has a significant impact on quality of life. Cecostomy tube insertion is a procedural option for cases refractory to medical management, however there is limited data investigating the long-term success and complication rate.
A retrospective review was performed evaluating patients at our centre undergoing cecostomy tube (CT) insertion between 2002 and 2018. The primary outcomes of the study were the rate of fecal continence at 1-year, and the incidence of unplanned exchanges prior to annual scheduled exchange. Secondary outcomes include the frequency of anaesthetic requirements and length of hospital stay. Descriptive statistics, t-test, and chi-square analysis was performed where appropriate using SPSS v25.
Of 41 patients, the average age at the time of initial insertion was 9.9 years with the average length of stay in hospital being 3.47 days. The most common etiology of bowel dysfunction was spina bifida, which was present in 48.8% (n = 20) of patients. Fecal continence was achieved in 90% (n = 37) of patients at 1 year and the average rate of cecostomy tube exchange was 1.3/year with an average of 3.6 general anaesthetics being required by patients and the average age of no longer requiring one being 14.9 years.
Analysis of patients undergoing cecostomy tube insertion at our centre has further supported the use of cecostomy tubes as a safe and effective option for management of fecal incontinence refractory to medical management. However, a number of limitations exist in this study including its retrospective design and failure to investigate changes in quality of life using validated questionnaires. Additionally, while our research provides greater insight to practitioners and patients what degree of care and types of complications or issues they may encounter with an indwelling tube over the long-term, our single-cohort design limits any conclusions that could be made regarding optimal management strategies for overflow fecal incontinence through direct comparison with other management strategies.
CT insertion is a safe and effective method for managing fecal incontinence due to constipation in the pediatric population, however, unplanned exchange of tube due to malfunction, mechanical breakage, or dislodgment occurs frequently and may impact quality of life and independence.

OBJECTIVE: To perform a scoping review of the literature evaluating patient preparation for prostate MRI.
METHODS: We conducted a search of English language literature, between 1989 and 2022 using MEDLINE and EMBASE for key terms: diet, enema, gel, catheter and anti-spasmodic agents linked to prostate MRI. Studies were reviewed for: level of evidence (LOE), study design and key results. Knowledge gaps were identified.
RESULTS: Three studies evaluated dietary modification in 655 patients. LOE was 3. All studies showed improved DWI and T2W image quality (IQ) and reduced DWI artifact. Nine studies evaluated enema use in 1551 patients. Mean LOE was 2.8 (range 2-3). Six studies reported IQ; DWI and T2W IQ were significantly improved with enema in 5/6 and 4/6 studies respectively. Only one study evaluated DWI/T2W lesion visibility which was improved with enema. One study evaluated impact of enema on eventual prostate cancer diagnosis, showing no benefit in false negative reduction. One study (LOE = 2, 150 patients) evaluated rectal gel; however, in combination with enema showing improved DWI and T2W IQ, lesion visibility and PI-QUAL compared to no preparation. Two studies evaluated use of rectal catheter in 396 patients. LOE was 3. One study showed improved DWI and T2W IQ and artifact compared to no preparation; however, the other showed inferior results comparing rectal catheter to enema. Six studies evaluated anti-spasmodic agent use in 888 patients. Mean LOE was 2.8 (range 2-3). Benefit of anti-spasmodic agent use on image quality and artifact on DWI and T2W are conflicting with no clear benefit.
CONCLUSIONS: Data evaluating patient preparation for prostate MRI is limited by level of evidence, study design and conflicting results. The majority of published studies do not evaluate impact of patient preparation on eventual prostate cancer diagnosis.

To map available scientific evidence about the pediatric population with spina bifida submitted to transanal irrigation to manage signs and symptoms of neurogenic bowel.
This research was developed according to recommendations from the Joanna Briggs Institute Reviewers\' Manual and the PRISMA Extension for Scoping Reviews. Searches were carried out in the databases: CINAHL, Medline/Pubmed, Scielo, Scopus, Web of Science, Embase, LILACS, Proquest, and the CAPES catalog of theses and dissertations. Quantitative and qualitative studies on the topic were included, as long as they dealt with this population. There was no predetermined time frame.
The authors found 1.020 studies, selected 130 for close reading, and included 23 in the review, all of which had been published from 1989 to 2021. The authors mapped the characteristics of the studies, including their definitions of concepts and use of scales, criteria for the indication of transanal irrigation, training to carry out the procedure, devices and solutions used, number and frequency of transanal irrigations, health care actions, time spent, associated complications, complementary exams, adherence rate, follow-up, and outcomes, focusing on the benefits for bowel management.
Despite the variability of evaluation parameters and term definitions, evidence suggests that transanal irrigation is a safe and effective method to manage fecal incontinence. Studies in the field are likely to grow, using standardized scales and longitudinal follow-ups. The authors suggest further research on transanal irrigation in the pediatric population with spina bifida in the Latin American context.

BACKGROUND: Anal sinusitis is an acute or chronic inflammation of the anal sinus, anal flap, and anal glands. There are many traditional Chinese medicine (TCM) therapies for anal sinusitis, and most of them can achieve satisfactory results. Retention enema is one effective treatment for anal sinusitis. Although a number of studies have shown the effectiveness of retention enema with TCM in treating anal sinusitis, the results are inconsistent. Therefore, a meta-analysis was carried out in this study to evaluate the efficacy and safety of retention enema with TCM in the treatment of anal sinusitis.
METHODS: Randomized controlled trials on TCM retention enema for treating anal sinusitis were retrieved from PubMed, EMBASE, The Cochrane Library, CNKI, WanFang databases and VIP databases. The search time limit was from the database establishment to November 15, 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Risk of bias was assessed using the Cochrane Risk of Bias Tool (RoB 2.0). The meta-analysis was conducted by RevMan 5.3.
RESULTS: The results of this study will be published in a peer-reviewed publication.
CONCLUSIONS: This systematic review and meta-analysis will provide evidence for the efficacy and safety of TCM retention enema in the treatment of anal sinusitis.

Although proctoclysis (enema) is a historically proven, safe and cost-effective rehydration method that needs little training for users and can effectively replace intravenous hydration in different care settings, it is an uncommon choice for hydration in children with fever and is often missing in official guidelines. To evaluate the usefulness of proctoclysis, this study provides a scoping review of the existing literature. The matched literature was labelled in 5 categories, identifying 6 indication fields that are emphasized in the literature on rectal rehydration. The analysis showed that proctoclysis is mostly used in the context of diagnostic procedures, constipation or in the treatment of a gastrointestinal disease. It is also described as a quick, safe and cost-effective intervention for fluid replacement in emergency, critical care or resource-scarce settings. There are also socio-cultural variations in its use Additionally, we performed a survey on attitudes and experience of medical doctors towards proctoclysis based on a semi-structured questionnaire. In the survey, we analysed the experience of 35 medical doctors from 8 countries. Although we found a general acceptance of enema as beneficial in both hospitalized patients and in home care, doctors expressed the need for more experience with enema and the need for more education materials in order to effectively perform the procedure. Based on our findings, we suggest that further research is necessary examining the attitude towards proctoclysis among parents, nurses and doctors. Enema can have a considerable clinical advantage during home care for gastroenteritis or other infectious diseases with fever to prevent insufficient oral fluid intake resulting in a negative fluid balance. Risks and safety issues are rare and should be considered. However, due to its low level of social acceptability in order to reduce refusal rate, more education is necessary for both medical providers and parents.
