Identification of Iatrogenic Perforation in Pediatric Gastrointestinal Endoscopy.

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.

Endoscopic management of esophageal mucosal bridges in children with esophageal atresia.

BACKGROUND AND STUDY AIMS: Esophageal mucosal bridge (EMB) may be diagnosed at the anastomotic site in children operated on for esophageal atresia (EA) but so far only a few cases (n = 4) have been reported. This study aimed to characterize EMB in children with EA, risk factors, and treatment. PATIENTS AND METHODS: This retrospective multicenter study recorded patient's characteristics, EMB diagnosis circumstances, endoscopic management, follow-up, and EMB recurrence in children with EA aged less than 18 years, compared with paired EA patients without EMB. RESULTS: Thirty patients were included (60% male, 90% EA/tracheoesophageal fistula, 43% associated malformations). Compared to 44 paired controls, EMB was associated with a history of nasogastric tube feeding (31% vs. 9.1%, p = 0.02) and severe gastroesophageal reflux disease (history of fundoplication: 41.4% vs. 13.6%, p < 0.01). 77% had symptoms (food impaction and/or dysphagia). Endoscopic management was performed in 53% of patients (83% electrocoagulation) with no technical difficulties or complications. 80% of the symptomatic patients with EMB improved after endoscopic treatment, independently of anastomotic stricture dilatation or not. CONCLUSION: EMB endoscopic management by electrocoagulation is safe and often leads to symptom improvement.

Complications of one-step button percutaneous endoscopic gastrostomy in children.

To assess the complications of one-step button percutaneous endoscopic gastrostomy (B-PEG) and determine risk factors for developing stomal infections or gastropexy complications. A retrospective study of 679 children who underwent a B-PEG procedure in a single tertiary care center over a 10-year period to December 2020 was conducted. Patient characteristics, early complications (occurring ≤ 7 days after the procedure), late complications (> 7 days after the procedure), and outcomes were collected from medical records. A list of potential risk factors, including age at procedure, prematurity, underlying neurological disease, and undernutrition, was determined a priori. At least 1 year of follow-up was available for 513 patients. Median follow-up duration was 2.8 years (interquartile range 1.0-4.9 years). Major complications were rare (< 2%), and no death was related to B-PEG. Early complications affected 15.9% of the study population, and 78.0% of children presented late complications. Development of granulation tissue was the most common complication followed in frequency by tube dislodgment and T-fastener complications. Only 24 patients (3.5%) presented stomal infections. Young age at the time of PEG placement (odds ratio (OR) 2.34 [1.03-5.30], p = .042) was a risk factor for developing peristomal infection. T-fastener migration occurred in 17.3% of children, and we found underlying neurological disease was a protective factor (OR 0.59 [0.37-0.92], p = .019).  Conclusion: B-PEG is a safe method and associated with a low rate of local infection. However, T-fasteners are associated with significant morbidity and require particular attention in young and premature infants. What is Known: • Percutaneous endoscopic gastrostomy (PEG) is the preferred method to provide long-term enteral nutrition in children to prevent malnutrition. The Pull-PEG method is still the most commonly used with complications , such as stomal infection. Since its description, only a few studies have reported postoperative complications of one-step button PEG (B-PEG). What is New: • T-fastener complications were not rare, and underlying neurologic disease was a protective factor. A very low rate of stomal infection was described, and young age at the time of PEG placement was a risk factor. The B-PEG is a safe method with fewer major complications than P-PEG in children.

Endoscopic Gastrojejunostomy in Infants and Children.

OBJECTIVE: To evaluate the feasibility of endoscopic gastrojejunal tube (GJT) placement in infants and children. STUDY DESIGN: All children undergoing endoscopic GJT placement between January 2010 and December 2019 were included in this single-center retrospective study. Difficulties with and failure of GJT placement, complication rates, and device longevity, efficacy, and duration were assessed. RESULTS: A total of 107 children, median age 10 months (IQR, 5.0-23.0 months) and median weight 6.6 kg (IQR, 5.3-9.5 kg), underwent endoscopic GJT placement using the gastric stoma to introduce the endoscope (one step: n = 36 of 107; 33.6%). Endoscopic placement was successful in 99%. Eight periprocedure complications occurred, including 1 pneumoperitoneum requiring exsufflation, 2 acute pulmonary hypertension episodes leading to death in 1 case, and 5 episodes of bronchospasm. Minor complications were frequent and mostly mechanical (79%), whereas major complications were rare (5.6%): intussusception (n = 4), intestinal perforation (n = 1), and pneumoperitoneum (n = 1). Ten patients died. Of the 97 patients who lived, 85 (87%) were weaned from jejunal feeding at a median of 179 days (IQR, 69-295 days) after initiation. Among them, 30 (35.2%) required fundoplication. Weight for age z-score was significantly higher at weaning. CONCLUSIONS: GJT placement is feasible in children, even low-weight infants. Complications are frequent but are mostly minor.

Prebiotic Supplementation during Lactation Affects Microbial Colonization in Postnatal-Growth-Restricted Mice.

BACKGROUND: An inadequate perinatal nutritional environment can alter the maturation of the intestinal barrier and promote long-term pathologies such as metabolic syndrome or chronic intestinal diseases. The intestinal microbiota seems to play a determining role in the development of the intestinal barrier. In the present study, we investigated the impact of consuming an early postnatal prebiotic fiber (PF) on growth, intestinal morphology and the microbiota at weaning in postnatal-growth-restricted mice (PNGR). METHODS: Large litters (15 pups/mother) were generated from FVB/NRj mice to induce PNGR at postnatal day 4 (PN4) and compared to control litters (CTRL, 8 pups/mother). PF (a resistant dextrin) or water was orally administered once daily to the pups from PN8 to PN20 (3.5 g/kg/day). Intestinal morphology was evaluated at weaning (PN21) using the ileum and colon. Microbial colonization and short-chain fatty acid (SCFA) production were investigated using fecal and cecal contents. RESULTS: At weaning, the PNGR mice showed decreased body weight and ileal crypt depth compared to the CTRL. The PNGR microbiota was associated with decreased proportions of the Lachnospiraceae and Oscillospiraceae families and the presence of the Akkermansia family and Enterococcus genus compared to the CTRL pups. The propionate concentrations were also increased with PNGR. While PF supplementation did not impact intestinal morphology in the PNGR pups, the proportions of the Bacteroides and Parabacteroides genera were enriched, but the proportion of the Proteobacteria phylum was reduced. In the CTRL pups, the Akkermansia genus (Verrucomicrobiota phylum) was present in the PF-supplemented CTRL pups compared to the water-supplemented ones. CONCLUSIONS: PNGR alters intestinal crypt maturation in the ileum at weaning and gut microbiota colonization. Our data support the notion that PF supplementation might improve gut microbiota establishment during the early postnatal period.

Tube Feeding in Neurologically Disabled Children: Hot Topics and New Directions.

Tube feeding is a therapeutic intervention that is aimed at providing nutritional support and is important in the nutritional and gastrointestinal management of children with neurological disability (ND) worldwide. Since the publication of the first European Society of Gastroenterology, Hepatology, and Nutrition (ESPGHAN) consensus paper in 2017, some aspects of tube-feeding modalities have attracted the interest of the scientific community more than others, including the type of enteral formulas, enteral access, and the challenging practice of tube weaning. The purpose of this review was to report on the most recent hot topics and new directions in tube-feeding strategies for children with ND.
