ABSTRACT
OBJECTIVES: Iatrogenic viscus perforation in pediatric gastrointestinal endoscopy (GIE) is a very rare, yet potentially life-threatening event. There are no evidence-based recommendations relating to immediate post-procedure follow-up to identify perforations and allow for timely management. This study aims to characterize the presentation of children with post-GIE perforation to better rationalize post-procedure recommendations. METHODS: Retrospective study based on unrestricted pooled data from centers throughout Europe, North America, and the Middle East affiliated with the Endoscopy Special Interest Groups of European Society for Paediatric Gastroenterology Hepatology and Nutrition and North American Society for Pediatric Gastroenterology Hepatology and Nutrition. Procedural and patient data relating to clinical presentation of the perforation were recorded on standardized REDCap case-report forms. RESULTS: Fifty-nine cases of viscus perforation were recorded [median age 6 years (interquartile range 3-13)]; 29 of 59 (49%) occurred following esophagogastroduodenoscopy, 26 of 59 (44%) following ileocolonoscopy, with 2 of 59 (3%) cases each following balloon enteroscopy and endoscopic retrograde cholangiopancreatography; 28 of 59 (48%) of perforations were identified during the procedure [26/28 (93%) endoscopically, 2/28 (7%) by fluoroscopy], and a further 5 of 59 (9%) identified within 4 hours. Overall 80% of perforations were identified within 12 hours. Among perforations identified subsequent to the procedure 19 of 31 (61%) presented with pain, 16 of 31 (52%) presented with fever, and 10 of 31 (32%) presented with abdominal rigidity or dyspnea; 30 of 59 (51%) were managed surgically, 17 of 59 (29%) managed conservatively, and 9 of 59 (15%) endoscopically; 4 of 59 (7%) patients died, all following esophageal perforation. CONCLUSIONS: Iatrogenic perforation was identified immediately in over half of cases and in 80% of cases within 12 hours. This novel data can be utilized to generate guiding principles of post-procedural follow-up and monitoring. PLAIN LANGUAGE SUMMARY: Bowel perforation following pediatric gastrointestinal endoscopy is very rare with no evidence to base post-procedure follow-up for high-risk procedures. We found that half were identified immediately with the large majority identified within 12 hours, mostly due to pain and fever.

OBJECTIVE/BACKGROUND: Endoscopic balloon dilatation (EBD) has been shown to be effective and safe in adults with stricturing Crohn disease (CD) yet pediatric data is sparse. We aimed to assess efficacy and safety of EBD in stricturing pediatric CD. METHODS: International collaboration included 11 centers from Europe, Canada, and Israel. Recorded data included patient demographics, stricture features, clinical outcomes, procedural adverse events, and need for surgery. Primary outcome was surgery-free over 12 months and secondary outcomes were clinical response and adverse events. RESULTS: Eighty-eight dilatations were performed over 64 dilatation series in 53 patients. Mean age at CD diagnosis was 11.1 (±4.0) years, stricture length 4 cm [interquartile range (IQR) 2.8-5], and bowel wall thickness 7 mm (IQR 5.3-8). Twelve of 64 (19%) patients underwent surgery in the year following the dilatation series, at a median of 89 days (IQR 24-120; range 0-264) following EBD. Seven of 64 (11%) had subsequent unplanned EBD over the year, of whom two eventually underwent surgical resection. Two of 88 (2%) perforations were recorded, 1 of whom was managed surgically, and 5 patients had minor adverse events managed conservatively. There was a significant improvement in all clinical measures following EBD with weighted pediatric CD activity index-defined remission increasing from 13% at baseline to 44%, 46%, and 61%, and absence of obstructive symptoms in 55%, 53%, and 64% of patients at week 2, 8, and 24 respectively. CONCLUSIONS: In this largest study of EBD in pediatric stricturing CD to date, we demonstrated that EBD is effective in relieving symptoms and avoiding surgery. Adverse events rates were low and consistent with adult data.

OBJECTIVES: Ileo-colonoscopy (IC) can be technically challenging because of unpredictable colonoscope loop formation. Aims of this study were to assess the risk of loop formation and to attempt to understand which factors were likely to predispose to which subtype of loop. METHODS: Prospective study conducted on children referred for an IC at Sheffield Children's Hospital. Presence and type of loop was objectively assessed using the magnetic endoscope imaging tool. RESULTS: Three hundred procedures were prospectively evaluated. Only 9% of paediatric ICs were loop-free. Alpha loops were the most common loop in children older than 5, whereas reverse alpha loops and a wider variety of complex and repetitive loops were observed in younger patients. Once a specific type of loop has formed, the risk of re-looping in a different way or in a different position of the colon is reduced. Left lateral starting position was found to increase the risk of reverse alpha loops and re-looping. Challenging loops, such as reverse alpha, were more frequent in males. Higher body mass index (BMI) was associated with an increased risk of alpha and deep transverse loops formation, while lower BMI with a higher incidence of reverse alpha and N loop. Loop formation did not prevent 100% ileal intubation. CONCLUSIONS: This study represents the first attempt to describe loop formation according to patient characteristics in a large paediatric series. Further studies are needed in order to establish if these findings could be helpful in simplifying the execution of IC procedures in children and facilitate the learning curve during endoscopy training programs.

BACKGROUND AND AIMS: Over-the-scope clips (OTSCs) are now becoming popular in endoscopy performed in adults for indications such as acute nonvariceal GI bleeding, anastomotic bleeding, and for closure of gastrocutaneous and postgastrostomy fistulae. Varied sizes of clip are available, but even the smallest, 8.5 to 9.8 mm in diameter with its loading device on the tip of the endoscope, increases device and endoscope intubation diameters up to 14.65 mm. This may present challenges in terms of the size of the patient in whom it might be used. OTSCs appear to be effective and safe in the hands of those who are trained appropriately in endoscopy on adult patients; however, the experience of OTSC application in children is not reported. Here we present results of a service evaluation of this technology at 2 regional/national referral pediatric endoscopy units in the United Kingdom and the United States. METHODS: Two tertiary centers' databases were searched to identify cases in which OTSCs were used. Demographics, presentation, anthropometry, comorbidities, efficacy, adverse events, and postprocedure follow-up were recorded, with identification of resolution or recurrence. RESULTS: OTSC procedures were performed on 24 occasions in 20 patients (11 girls) between February 2018 and February 2021. Patients had a mean age of 12 years (range, 5-17) and a mean weight of 44.42 kg (range, 18.2-70.3). Indications were nonhealing PEG site fistulae (n = 7), acute nonvariceal upper GI bleeding (ANUGIB) from gastric ulcers (5), ANUGIB from duodenal ulcers (3), nonhealing bleeding anastomotic ulcer (3), esophageal mucocutaneous fistula (1), and gastric perforation (1). Technical success was achieved in all but 1 case (95%), and clinical success was achieved in 18 cases (90%). CONCLUSIONS: The OTSC device appears to be effective in children (minimum age 5 years and minimum weight 18 kg) in a limited number of situations including anastomotic ulcer, closure of leaking PEG site, gastric perforation, and bleeding peptic ulcers. The operator should be an experienced endotherapeutic endoscopist with specific OTSC training, and the type and size of the OTSC device should be carefully considered, along with any comorbidities of the patient that may preclude success and/or lead to potential adverse events such as esophageal perforation.

PURPOSE: Congenital Partial Duodenal Obstruction (CPDO) caused by membranes/webs/diaphragms has traditionally been managed by open or laparoscopic duodenoduodenostomy or duodenojejunostomy. We report a two center case series where Natural Orifice Endoluminal technique (NOEL) was used to treat children with CPDO. METHODS: A retrospective case series was evaluated. Data collected included the duration of procedure, postoperative complications, length of stay, and need for further procedures. RESULTS: Fifteen patients were treated over a 10 year period by NOEL technique for late presenting CPDO. Four patients were managed at Sheffield Children's Hospital (Center A, UK), and 11 patients were managed in Bambino Gesù Hospital of Rome (Center B, Italy). 20% of the patients had more than one duodenal obstructing membrane. Both balloon dilatation and membrane incision techniques were used. Median follow up was 23â¯months (range 2-69) in Center A and 18â¯months (range 7-58) in Center B. 60% of patients were successfully treated with 1 NOEL procedure. 20% required 2 or 3 procedures to achieve long term luminal patency. 20% required surgery after NOEL failed to treat the partial obstruction definitively. One patient in Center A required radiological drainage of a retroperitoneal collection following perforation during NOEL. CONCLUSION: NOEL technique is feasible and effective in selected children with CPDO. Both balloon dilatation and incision techniques can be used. Care must be taken to rule out a second distal obstruction. We would recommend that all infants and children with CPDO owing to a fenestrated membrane should be considered for NOEL. TYPE OF STUDY: Case series. LEVEL OF EVIDENCE: Level IV.

INTRODUCTION: Endoscopy is integral to the diagnosis and management of many gastrointestinal problems in children. Recently the number of endoscopic procedures performed has increased considerably worldwide raising questions about their appropriateness and cost-efficacy. OBJECTIVES: The aim of the study was to determine the diagnostic yield (the likelihood that a procedure or test will provide information required to establish a diagnosis) of endoscopy in a paediatric population in a large tertiary referral centre and to determine the terminal ileum intubation (TII) rate of paediatric ileocolonosocopy (IC) in an active training environment and compare with previously calculated rates. METHODS: Random selection of cases from a theatre electronic database from a 30-month period covering April 2012 to October 2014. The data were collected for initial presenting symptoms; age at diagnosis; indications for endoscopy; endoscopic findings; histopathological findings; and any change in management postendoscopic procedure. The diagnostic yield of the endoscopies and the TII rate of IC were calculated. Change in and contribution to management was assessed. RESULTS: Median age 9.58 (0.5-16.5) years and M:F ratio 1:1.42. The positive diagnostic yield was 18.9% for oesophago-gastro-duodenoscopy alone, 32.6% for IC alone, and 39.2% when both occurred. In 45% management was actively changed due to endoscopy/histopathology findings and a significant management contribution occurred in all patients. TII was achieved in 98% of cases, which compares favourably to a TII rate of 89% at the same centre during the period 2009 to 2011. CONCLUSIONS: Diagnostic yield was 32.6% for IC and 39.2% when oesophago-gastro-duodenoscopy also occurred. A TII rate of 98% should be achievable in children. A change in management occurred in 45% and as a significant negative finding may be as important as a positive diagnosis for exclusion of suspected disorders, with consequent reassurance and change in management. Contribution to management was therefore identified in all cases.
