Glycopyrrolate Premedication and Procedure-Related Events in Pediatric Upper Endoscopy.

Glycopyrrolate premedication is used for pediatric upper endoscopy procedures, with limited clinical evidence for efficacy. We investigated whether glycopyrrolate use is associated with lower incidence of procedure-related events and serious adverse events (SAEs) using the Pediatric Sedation Research Consortium registry. Pediatric upper endoscopy procedures performed between April 27, 2020 and February 3, 2022 were included (N = 1046). The primary outcome was the incidence of any procedure-related events during induction, maintenance, or recovery, and the secondary outcome was incidence of SAEs. The event rate was 15%, including 30 SAEs (3%). On multivariable analysis, glycopyrrolate was not associated with the overall event rate (odds ratio [OR]: 1.08; 95% confidence interval [CI]: 0.72, 1.61), but was associated with lower odds of SAEs (OR: 0.34; 95% CI: 0.13, 0.91). Although glycopyrrolate was associated with lower odds of SAEs after accounting for patient and procedure characteristics, validation through prospective trials is needed to support its routine use in clinical practice.

Recent trends in foreign body ingestion (FBI) epidemiology: A national cohort study

Background and AimsForeign body ingestion (FBI) in children is a critical health concern. This study aimed to describe the epidemiology of FBI in children in Italy. MethodsWe retrospectively enrolled children <18 years admitted for FBI from January 2015 to December 2020. Data were collected across 21 hospitals with dedicated pediatric endoscopy services and normalized by the population of the corresponding municipalities. ResultsA total of 5,771 FBI cases were analyzed. FBI incidents showed consistent time trends across age groups, with most events occurring at home and being witnessed (94.7 %). Children <6 years accounted for 74.3 % of cases. Comorbidities were present in 5.3 % of cases, primarily neurologic/psychiatric disorders in older children (6–17 years). Blunt objects accounted for 65.5 % of ingestions. Young males commonly ingested button batteries, while females showed higher rates of ingesting hair products and jewelry. Most children were discharged (60 %) or observed briefly (75 % of total admissions), with endoscopic removal performed in 24 % of cases. ConclusionsRates of FBI have remained stable over the years, including during the COVID-19 pandemic. FBI predominantly occurs in domestic settings among healthy young children, particularly those ≤5 years old. These findings emphasize the need for preventive measures to reduce the impact of FBI among children.

Recent progress and current status of pancreatobiliary interventional endoscopic ultrasound in children.

In recent years, the usefulness of endoscopic ultrasound (EUS) has been recognized in children. A dedicated pediatric EUS scope has not been developed; in our experience, however, an adult EUS scope can be used. The American Society for Gastrointestinal Endoscopy Technical Committee status assessment report on pediatric endoscopy equipment provides some guidance on the feasibility of EUS according to body size. Careful monitoring is required, keeping in mind potential adverse events such as cervical esophageal perforation and unstable breathing due to tracheal compression. Most devices designed for interventional pancreatobiliary endoscopy are also available for children. Sedation or intubated general anesthesia (GA) is mandatory when performing interventional EUS (I-EUS). I-EUS for children is generally performed using GA in the operating room, but sedation in the endoscopy room is also possible under appropriate monitoring by pediatricians. I-EUS in the operating room is sometimes difficult for endoscopists to perform because of the unsuitable fluoroscopic imaging and the lack of familiar equipment and staff. Compared to GA, sedation in the endoscopy room facilitates easier and quicker repetition of procedures when necessary. Adult pancreatobiliary endoscopists perform most I-EUS procedures in the pediatric population because most pediatric endoscopists have few opportunities to perform EUS-related procedures and thus have difficulty maintaining their skills. To popularize I-EUS techniques for children, it will be necessary to establish a training program for developing pediatric endoscopists.

Assessment of risk factors for adverse events in analgosedation for pediatric endoscopy: A 10-year retrospective analysis.

Data regarding the occurrence of complications specifically during pediatric anesthesia for endoscopic procedures is limited. By evaluating such data, factors could be identified to assure proper staffing and preparation to minimize adverse events and improve patient safety during flexible endoscopy. This retrospective cohort study included children undergoing anesthesia for gastroscopy, colonoscopy, bronchoscopy, or combined endoscopic procedures over 10-year period. The primary study aim was to evaluate the incidence of complications and identify risk factors for adverse events. Overall, 2064 endoscopic procedures including 1356 gastroscopies (65.7%), 93 colonoscopies (4.5%), 235 bronchoscopies (11.4%), and 380 combined procedures (18.4%) were performed. Of the 1613 patients, 151 (7.3%) patients exhibited an adverse event, with respiratory complications being the most common (65 [3.1%]). Combination of gastrointestinal endoscopies did not lead to an increased adverse event rate (gastroscopy: 5.5%, colonoscopy: 3.2%). Diagnostic endoscopy as compared to interventional had a lower rate. If bronchoscopy was performed, the rate was similar to that of bronchoscopy alone (19.5% vs. 20.4%). Age < 5.8 years or body weight less than 20 kg, bronchoscopy, American Society of Anesthesiologists status ≥ 2 or pre-existing anesthesia-relevant diseases, and urgency of the procedure were independent risk factors for adverse events. For each risk factor, the risk for events increased 2.1-fold [1.8-2.4]. This study identifies multiple factors that increase the rate of adverse events associated anesthesia-based endoscopy. Combined gastrointestinal procedures did not increase the risk for adverse events while combination of bronchoscopy to gastrointestinal endoscopy showed a similar risk as bronchoscopy alone.

Pediatric advanced complex endoscopy team enhances endoscopy quality and provider satisfaction.

Therapeutic endoscopic procedures are increasingly necessary for children. Pediatric gastroenterologist training and experience with endoscopic hemostasis and other complex therapeutic endoscopy procedures are often limited. We evaluated the impact of the implementation of an advanced complex endoscopy (ACE) team, which provides 24/7 inpatient/outpatient back-up endoscopy support. We analyzed hemostasis quality outcomes in the 2 years before implementation of ACE (2018-2020) versus the year following the implementation of ACE (2020-2021). We analyzed pediatric gastroenterology provider satisfaction and perspectives with a survey that was distributed to faculty, fellows, and advanced practice providers 1 month before implementation of ACE and again 12 months following ACE implementation. Endoscopy volume and outcome metrics for hemostasis procedures, including latency to endoscopy, need for reintervention, and administration/diversity of hemostatic therapy, including multimodal therapy, improved in the year following implementation of the ACE (p < 0.05 for each). Survey results demonstrated a positive impact on provider endoscopy experience and high utilization of ACE. Twenty-two percent of providers reported activating ACE in the prior month and 66% in the prior year. Most providers who activated ACE were very satisfied (85%) or satisfied (7.7%). Eighty-three percent noted ACE had a positive impact on inpatients, and 50% noted a positive impact on outpatient endoscopy. Provider anxiety with endoscopy diminished post-ACE implementation (62% vs. 28%). Respondents unanimously found ACE beneficial to patient care (100%). ACE implementation was associated with improved provider perspectives surrounding endoscopy and significant improvement in hemostasis quality parameters, escalation of hemostasis procedure volume, and broadening the range of hemostasis interventions.

Diagnostic Yield of Same Setting Oesophago-Gastro-Duodenoscopy (OGD)and Colonoscopy for Pediatric Patients with Chronic Diarrhea

Abstract Background In patients with unexplained chronic diarrhea colonoscopy and upper GI endoscopy are helpful in the diagnosis. It is the routine practice in Ain Shams University pediatric endoscopy unit to perform both procedures at same setting for patients with unexplained chronic diarrhea. Aim of the Work To find out whether doing Oesophago-gastro-duodenoscopy (OGD) and colonoscopy in patients with chronic diarrhea in one setting is essential for the diagnosis of all cases. Patients and Methods Fifty patients presenting with chronic unexplained diarrhea (&amp;gt;4 weeks duration) in Paediatric Gastroenterology Unit, Children’s Hospital, Ain-Shams University were enrolled. After full history taking, physical examination, both endoscopies were performed biopsy taken and histopathological recording for each sample. Results Of 50 patients with chronic diarrhea included in our study; 23 (46%) had positive endoscopic findings in the OGD. Most common findings in esophagus and stomach were inflammation and erythema. while most common findings in duodenum were edema and flattened mucosa. Colonoscopy findings were positive in 50% of patients including inflammation, nodularity, and edema mostly in the ileum. 50% of endoscopied patients reached final diagnosis based on endoscopy and histopathology. Definitive diagnosis reached through EGD alone in (12%) of cases, through colonoscopy alone in (28%) and through both techniques in (60%). There was no statistical significant agreement between endoscopy findings and predominant gastrointestinal manifestations including different types of diarrhea, fecal calprotectin with p-value =0.150, and 0.833 respectively. There was no statistical significant agreement between final diagnosis and suspected GIT part involvement on initial clinical evaluation with p- value=0.805. Conclusion Endoscopy for upper gastrointestinal tract and colonoscopy at same day may be helpful in diagnosis of cases with chronic diarrhea as we can't decide which one to perform based on clinical presentation.

Comparison of propofol-based sedation and midazolam sedation in pediatric bidirectional endoscopy conducted by pediatric gastroenterologists.

The effectiveness and safety of propofol-based sedation and midazolam sedation in pediatric bidirectional endoscopy were compared. We retrospectively analyzed the cases of pediatric patients (≤15 years old) who had undergone bidirectional endoscopy, esophagogastroduodenoscopy, and colonoscopy by pediatric gastroenterologists. Demographic data, indications, sedatives/dosages, clinical outcomes, endoscopic findings, adverse events, and total patient time requirements (total time in which patients stay in our hospital) were compared in the two sedation groups. Ninety-one children (51 boys, 40 girls, mean age 13 years, range 9-15) treated at our hospital were enrolled. Propofol alone or in combination with midazolam and/or pentazocine was administered to 51 patients (propofol-based sedation group). Midazolam alone or in combination with pentazocine was administered to the other 40 patients (midazolam sedation group). In the propofol group, the following mean doses were used: propofol, 96 mg (range 40-145 mg); midazolam, 4.9 mg (range 3-5 mg); and pentazocine, 7.5 mg. In the midazolam group, the mean doses of midazolam and pentazocine were 6.2 mg (range 4-10 mg) and 15 mg, respectively. All procedures were successfully completed by pediatric gastroenterologists. The total procedure times and endoscopic findings were similar in the two groups, but the median patient time requirement in the propofol group was significantly shorter versus the midazolam group (7.3 h vs. 8.4 h, p < 0.001). No adverse events occurred in either group. Propofol-based sedation in pediatric bidirectional endoscopy was safely and effectively performed by pediatric gastroenterologists, and its patient time requirement was shorter than that for midazolam sedation.

Semiautomated electronic medical record based system for monitoring delayed adverse events in pediatric endoscopy and sedation.

To develop a semiautomated electronic medical record (EMR) system to track pediatric endoscopic procedural adverse event (AE) at a tertiary referral children's hospital. We developed an automated EMR based query for postprocedure AEs. Main outcome measurements within 30 days of procedure: return to emergency department, return to surgery, unplanned admissions and admissions with longer than intended stays. Events were graded using a recently described classification system for postendoscopy events and tracked for a 36-month period, from January 2017 to December 2019. Development of a semi-automated system was successful in comprehensive identification of endoscopy and sedation related AE. A total of 193 AEs (2%) were identified in all three categories. Seventy cases (0.7%) were noted to be a direct result of an endoscopic procedure. Of these cases, 31 (44%) were noted to be Grade 3, 5 cases (7%) Grade 4, and no Grade 5 AE occured. Higher rates of AE were observed after therapeutic procedures versus diagnostic (2.6% vs. 0.3%, p = <0.00001). AEs related to sedation occurred in 0.5% of procedures with the majority (84%) reported in patients with American Society of Anesthesia classification of 3 or greater. Diagnostic endoscopy remains a safe procedure and risk of both endoscopy and sedation related AE are low. Therapeutic procedures carry a higher risk but are still overwhelmingly safe. Institutional investment in this EMR based system allowed for sustainability and comprehensive tracking of endoscopy related AE.

Surveillance Endoscopy in Pediatric Esophageal Atresia: Toward an Evidence-Based Algorithm.

Individuals with esophageal atresia (EA) have lifelong increased risk for mucosal and structural pathology of the esophagus. The use of surveillance endoscopy to detect clinically meaningful pathology has been underexplored in pediatric EA. We hypothesized that surveillance endoscopy in pediatric EA has high clinical yield, even in the absence of symptoms. The medical records of all patients with EA who underwent at least 1 surveillance endoscopy between March 2004 and March 2023 at an international EA referral center were retrospectively reviewed. The primary outcomes were endoscopic identification of pathology leading to an escalation in medical, endoscopic, or surgical management. Logistic regression analysis examined predictors of actionable findings. Nelson-Aalen analysis estimated optimal endoscopic surveillance intervals. Five hundred forty-six children with EA underwent 1,473 surveillance endoscopies spanning 3,687 person-years of follow-up time. A total of 770 endoscopies (52.2%) in 394 unique patients (72.2%) had actionable pathology. Esophagitis leading to escalation of therapy was the most frequently encountered finding (484 endoscopies, 32.9%), with most esophagitis attributed to acid reflux. Barrett's esophagus (intestinal metaplasia) was identified in 7 unique patients (1.3%) at a median age of 11.3 years. No dysplastic lesions were identified. Actionable findings leading to surgical intervention were found in 55 children (30 refractory reflux and 25 tracheoesophageal fistulas). Significant predictors of actionable pathology included increasing age, long gap atresia, and hiatal hernia. Symptoms were not predictive of actionable findings, except dysphagia, which was associated with stricture. Nelson-Aalen analysis predicted occurrence of an actionable finding every 5 years. Surveillance endoscopy uncovers high rates of actionable pathology even in asymptomatic children with EA. Based on the findings of the current study, a pediatric EA surveillance endoscopy algorithm is proposed.

Simulation-based training of endoscopic hemostasis for Japanese pediatric endoscopy learners: a pilot program

Background and AimsEndoscopic hemostasis training, often in emergencies, can be challenging for pediatric endoscopists. This study aimed to establish hands-on seminar sessions using the novel clip hemostasis simulator, and to explore the underlying concerns about endoscopic hemostasis among pediatric endoscopists and the potential of simulator-based training (SBT). MethodsA SBT course was incorporated into seminars by the Japanese Society for Pediatric Gastroenterology, Hepatology, and Nutrition. Surveys with Visual Analog Scale (VAS, 0-100) completed by consenting pediatricians during four seminars from October 2021 to March 2023, were compared with the responses of adult gastrointestinal (GI) residents and junior residents. ResultsFifty-two pediatric endoscopists (median age 31, PGY 7) were enrolled. A median VAS score of 47 (IQR 23.5-65) for understanding endoscopic hemostasis, significantly lower than adult GI residents (median 76, IQR 58-82, P<0.001) and comparable to junior residents (median 54, IQR 50-65). Pediatric endoscopists' confidence in independently performing hemostasis was low, with a median score of 0 (IQR 0-16.5), below adult GI residents (median 67, IQR 49-77, P<0.001) and junior residents (median 11.5, IQR 10-39, P=0.014). Regarding skill enhancement by SBT, a median score of 94.5 showed high and no significant difference from junior residents and adult GI residents. All pediatric endoscopists expressed interest in repeated SBT sessions. Discussion and Future ProspectsPediatric endoscopists were concerned about their competence in endoscopic hemostasis. The simplified SBT programs with the simulator, may potentially improve their skills and confidence.

Bispectral Index versus the University of Michigan Sedation Scale in assessing sedation depth during pediatric drug-induced sleep endoscopy.

Bispectral Index (BIS) and University of Michigan Sedation Scale (UMSS) were two commonly used methods of monitoring the sedation depth, but their correlation was not clear. The purpose of this study is to ascertain if BIS correlates with UMSS in determining the sedation level during pediatric drug-induced sleep endoscopy (DISE). One-hundred children, aged 36-143 months, with ASA I~II grade, were enrolled. They were subject to general anesthesia for an elective adenotonsillectomy. Two drug regimens were used. After UMSS ≥ 3, the sites of airway obstructions were located by checking the supraglottic airway structures with a fibrous laryngoscope. UMSS scores, BIS values, electromyography (EMG), and signal quality indices (SQIs) were recorded at the pre-medication and pre-DISE baseline (T0), 5 min subsequent to medication administration but prior to DISE initiation (T1), 1 min after DISE was initiated (T2), 1 min after DISE was completed (T3), 1 min subsequent to tracheal intubation (T4), 1 min following extubation (T5), and 30 min past extubation (T6). There were strong correlations between BIS monitor readings and UMSS scores for total and two regimens. Kappa values revealed moderate agreement between BIS and UMSS for total and two regimens. The agreement rates were 67.47% for the total, 61.43% for Regimen 1, and 73.42% for Regimen 2, respectively. BIS correlates with UMSS in determining the sedation level during pediatric DISE for two regimens. BIS might serve as an appropriate indicator of sedation intensity when UMSS could not be used.

Mobile health technology in pediatric EGD quality indicators assessment: results from a national program of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition

Background and aimsUpper endoscopy procedures (UEP, esophagogastroduodenoscopy [EGDS] and retrograde endoscopic retrograde cholangiography [ERCP]) are an established standard of care in pediatric gastroenterology. The Pediatric endoscopy quality improvement network (PEnQuIN) recently published its pediatric-specific endoscopy quality guidelines. This study, initiated by the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP), aims to evaluate the adherence of Italian Pediatric Endoscopy Centers to these established quality standards. MethodsConducted between April 2019 and March 2021, this nationwide study utilized a smartphone app-based approach. Data encompassing pediatric endoscopy facilities, patient profiles, endoscopy indications, 17 procedure-related PEnQuIN indicators, and a GHAA-9m patient satisfaction questionnaire were systematically collected. ResultsA comprehensive analysis of 3582 procedures from 24 PECs revealed that 2654 (76%) were UEP. The majority of centers (75%) involved more than one operator, with 9 PEC incorporating adult endoscopists, responsible for 5% of UEPs. Overall, adherence to quality standards was good; however, areas of improvement include sub-optimal reporting of sedation details, adherence to disease-specific guidelines, and patient satisfaction questionnaire completeness (56%). The complication rate aligned with literature standards (1%), and patient satisfaction was generally high. A noteworthy observation was a 30% decrease monthly reporting rate and a shift in disease-specific patterns following the COVID-19 outbreak. ConclusionsPediatric UEP practices in Italy adhere well to established quality standards. Emphasizing the adoption of disease-specific guidelines is crucial for optimizing resources, enhancing diagnostic accuracy, and minimizing unnecessary procedures. Prioritizing patient satisfaction is important for immediate enhancements in practice as well as for future research endeavors.

Comparison of remimazolam and propofol combined with low dose esketamine for pediatric same-day painless bidirectional endoscopy: a randomized, controlled clinical trial.

Background: Remimazolam has shown similar or even superior properties to propofol in procedural sedation in adults, but few studies have been conducted in pediatric populations. Thus, we aimed to compare the effect and safety of remimazolam and propofol combined with low dose esketamine for pediatric same-day bidirectional endoscopy (BDE). Methods: Pediatrics <18years scheduled for elective BDE under sedation were included and randomly assigned to remimazolam group (R group) or propofol group (P group). The primary outcome was the success rate of sedation. Secondary outcomes include sedation-related information and adverse events. Mean arterial pressure (MAP), heart rate (HR), and perfusion index (PI) were recorded during sedation. Results: A total of 106 patients were enrolled and analyzed. The success rate of sedation was 100% in both groups. Compared with the P group, the induction time of the R group was significantly prolonged (p < 0.001), and the incidence of injection pain, intraoperative respiratory depression, hypotension and bradycardia was significantly lower (p < 0.001). The changes in MAP, HR and PI were relatively stable in the R group compared with the P group. Additionally, awake time significantly decreased with age by approximately 1.12 index points for each increase in age in the P group (p = 0.002) but not in the R group (p > 0.05). Furthermore, the decline in PI and PI ratio during BDE was related to body movement in the P group. Conclusion: Remimazolam combined with low dose esketamine has a non-inferior sedative effect than propofol for pediatric BDE, with no injection pain, less respiratory depression, more stable hemodynamics. Moreover, early detection of the decline in PI may avoid harmful stimulation under light anesthesia.

Review on Advances in Pediatric Endoscopy in the Management of Inflammatory Bowel Disease

Over the past decades, an increased importance has been given to gastrointestinal (GI) endoscopy in the management of children with inflammatory bowel diseases (IBD), considering that mucosal healing has been recognized as the optimal endpoint in the treat-to-target paradigm. The recent advances in technology and anesthesia have facilitated the comprehensive evaluation of the GI tract. In this review, we will discuss the role of ileocolonoscopy, upper GI endoscopy, and device-assisted enteroscopy in the work-up and management of pediatric Crohn’s disease (CD) and ulcerative colitis, with particular attention on non-invasive endoscopic techniques, such as wireless capsule endoscopy. We will also analyze the most commonly used endoscopic scoring systems, including small bowel scoring systems and endoscopic recurrence grading of neo-terminal ileum CD. Moreover, we will focus on the endoscopic management of complications, such as strictures, that commonly require surgery. Lastly, we will discuss cancer surveillance in children with IBD, with particular consideration of the role of high-definition endoscopic equipment and chromoendoscopy in dysplasia detection rates.

A guide on transnasal endoscopy: setting up a pediatric unsedated endoscopy program.

Unsedated transnasal endoscopy is becoming an increasingly popular option for the evaluation of upper gastrointestinal tract disorders in adults and children worldwide. This innovative technology has transformative potential as it provides for a more efficient, safe, and cost-effective method for endoscopy and reduces the risks associated with anesthesia, which is particularly relevant in pediatrics as endoscopy is commonly done under general anesthesia or conscious sedation. The aim is to address knowledge gaps amongst pediatric gastroenterologists who may be considering the development of a TNE program, detailing how to implement sedation-free TNE into practice for pediatric patients and current and forthcoming technologies. We conducted a comprehensive review of current literature and collection of data from experts and clinicians in the field on how sedation-free programs were started and being conducted. We aimed to collate the data to provide a guide to address knowledge gaps with a focus on setting up and starting a sedation-free endoscopy program. Here in, we provide a detailed guide for implementing a sedation-free endoscopy program in pediatrics including design and layout of a TNE unit, special staffing needs, equipment, current and forthcoming technologies, financial considerations and training considerations. We highlight special considerations that are relevant in pediatrics incorporating distraction or dissociation techniques such as Virtual Reality Systems, developmentally appropriate preparation for children, and topical analgesia. Sedation-free endoscopy is a rapidly growing option for pediatric patients. Development of an unsedated pediatric endoscopy program will improve patient care, decrease the need for anesthesia, provide a lower cost and safe alternative to traditional sedated endoscopy, and is a viable component to a pediatric gastroenterology practice.

Clinical Application of Pediatric Sleep Endoscopy: An International Survey.

To investigate through an international survey the actual clinical application of drug-induced sleep endoscopy (DISE) in pediatric patients with obstructive sleep apnea (OSA) and to clarify the use, application, clinical indications, and protocol of pediatric DISE. A specific survey about pediatric DISE was initially developed by five international otolaryngologists with expertise in pediatric sleep apnea and drug-induced sleep endoscopy and was later spread to experts in the field of sleep apnea, members of different OSA-related associations. A total of 101 participants who answered all the survey questions were considered in the study. Sixty-four sleep apnea experts, equivalent to 63.4% of interviewed experts, declared they would perform DISE in pediatric OSA patients. A total of 81.9% of responders agreed to consider the DISE as the first diagnostic step in children with persistent OSA after adenotonsillectomy surgery, whereas 55.4% disagreed with performing DISE at the same time of scheduled adenotonsillectomy surgery to identify other possible sites of collapse. In the case of young patients with residual OSA and only pharyngeal collapse during DISE, 51.8% of experts agreed with performing a velopharyngeal surgery. In this case, 27.7% disagreed and 21.4% were neutral. Pediatric DISE is internationally considered to be a safe and effective procedure for identifying sites of obstruction and collapse after adenotonsillectomy in children with residual OSA. This is also useful in cases of patients with craniofacial malformations, small tonsils, laryngomalacia or Down syndrome to identify the actual site(s) of collapse. Despite this evidence, our survey highlighted that pediatric DISE is not used in different sleep centers.

Pediatric endoscopy in times of pandemic: A nationwide retrospective analysis

BackgroundGastrointestinal endoscopy is a procedure that carries an increased risk of transmission of SARS-CoV-2 infection to medical staff. In patients, COVID-19 is a risk factor for adverse events of medical procedures. This study analyzed the real-life risk of, and factors contributing to, infection transmission to endoscopic personnel, and possible adverse events of the endoscopy procedure and anesthesia in children with COVID-19. MethodsNationwide retrospective analysis of medical records of children with confirmed SARS-CoV-2 infection who underwent gastrointestinal endoscopy in Poland between February 2020 and February 2022. ResultsFifty-eight patients were included in the analysis, 35% of whom had COVID-19 symptoms at the time of endoscopy. The dominant indications for endoscopy were foreign body or corrosive substance ingestion and gastrointestinal bleeding. Nine cases of virus transmission were registered among endoscopic personnel. In all of these cases, the endoscopy team was unaware of the patient's infection (p < 0.01), although symptoms were present in 78% of the children. Lack of use of personal protective equipment was the strongest predictor of SARS-CoV-2 transmission (p < 0.01). The risk of infection was not statistically significantly dependent on the method of anesthesia, intubation or the type of endoscopy. No statistically significant correlation was found between symptomatic infection and adverse events of endoscopy or anesthesia occurrence. There was one reported anesthesia-related adverse event involving extubation difficulties due to worsening respiratory infection symptoms. ConclusionsThe risk of transmitting SARS-CoV-2 to endoscopic personnel during procedures in children is low and depends on compliance with infection prevention and control measures. Performing gastrointestinal endoscopy in children with COVID-19 does not appear to be associated with an increased risk of adverse events.

Current Pediatric Endoscopy Training Situation in the Asia-Pacific Region: A Collaborative Survey by the Asian Pan-Pacific Society for Pediatric Gastroenterology, Hepatology and Nutrition Endoscopy Scientific Subcommittee.

To date, there is no region-specific guideline for pediatric endoscopy training. This study aimed to illustrate the current status of pediatric endoscopy training in Asia-Pacific region and identify opportunities for improvement. A cross-sectional survey, using a standardized electronic questionnaire, was conducted among medical schools in the Asia-Pacific region in January 2024. A total of 57 medical centers in 12 countries offering formal Pediatric Gastroenterology training programs participated in this regional survey. More than 75% of the centers had an average case load of <10 cases per week for both diagnostic and therapeutic endoscopies. Only 36% of the study programs employed competency-based outcomes for program development, whereas nearly half (48%) used volume-based curricula. Foreign body retrieval, polypectomy, percutaneous endoscopic gastrostomy, and esophageal variceal hemostasis, that is, sclerotherapy or band ligation (endoscopic variceal sclerotherapy and endoscopic variceal ligation), comprised the top four priorities that the trainees should acquire in the autonomous stage (unconscious) of competence. Regarding the learning environment, only 31.5% provided formal hands-on workshops/simulation training. The direct observation of procedural skills was the most commonly used assessment method. The application of a quality assurance (QA) system in both educational and patient care (Pediatric Endoscopy Quality Improvement Network) aspects was present in only 28% and 17% of the centers, respectively. Compared with Western academic societies, the limited availability of cases remains a major concern. To close this gap, simulation and adult endoscopy training are essential. The implementation of reliable and valid assessment tools and QA systems can lead to significant development in future programs.

Which Alarm Symptoms Are Associated With Abnormal Gastrointestinal Endoscopy Among Thai Children?

Alarm symptoms (red flag signs) are crucial indications for management decisions on pediatric gastrointestinal endoscopy. We aimed to identify items in the alarm symptoms and pre-endoscopic investigations that predict abnormal endoscopy results. A retrospective descriptive study was conducted among children aged under 18 years undergoing endoscopy. The patients were classified into normal and abnormal endoscopic groups. The incidence of alarm symptoms and pre-endoscopic investigations were compared between the groups. Univariate and multivariate logistic regression analyses were performed to determine independent risk factors for abnormal endoscopy. Of 148 participants, 66 were classified in the abnormal endoscopy group. Compared with the normal group, the abnormal group had a significantly higher prevalence of alarm symptoms. Moreover, hematemesis/hematochezia, anemia, low hemoglobin level, hypoalbuminemia, rising erythrocyte sedimentation rate, increased serum lipase, and blood urea nitrogen/creatinine ratio were significantly higher in the abnormal endoscopy group than in the normal group. Multivariate logistic regression analysis indicated that hematemesis/hematochezia and low hemoglobin level were independent risk factors for abnormal endoscopy. The alarm symptoms and pre-endoscopic investigations were evaluated using predictive factors for abnormal pediatric endoscopic findings. According to multivariate logistic regression analysis, hematemesis/hematochezia and low hemoglobin levels were independent risk factors for abnormal endoscopy.
