Anastomotic ulceration is a known complication of short gut syndrome, which can be complicated by concurrent iron deficiency and chronic bleeding. Diagnosis is confirmed through endoscopy, typically performed for the investigation of severe anemia. Inflammatory colitis in short gut syndrome has been previously reported; therefore, it is important to treat both ulceration and inflammation. Currently, no effective therapies are available. Herein, we describe the case of a child with short gut syndrome who subsequently developed anastomotic ulcers with recurrent severe bleeding and was successfully treated with endoscopic argon plasma cauterization for circumferential ulcerations, followed by a prolonged course of oral enteric budesonide. This intervention could be a potential and beneficial nonsurgical treatment for anastomotic ulceration.
Objectives: This study aimed to evaluate the current clinical practice of Dutch pediatric gastroenterologists regarding the surveillance for colorectal dysplasia and cancer in pediatric ulcerative colitis (UC), including adherence to guidelines, the initiation and interval of surveillance and applied endoscopy techniques.
Methods: A clinical vignette-based survey was distributed among all 47 pediatric gastroenterologists who are registered and working in the Netherlands.
Results: Thirty-three pediatric gastroenterologists treating children with UC, completed the questionnaire (response rate 70%). Of these respondents, 23 (70%) do conduct endoscopic surveillance in their UC patients. Adherence to any of the available guidelines was reported by 82% of respondents. Twenty-four of 31 respondents (77%) indicated the need for development of a new guideline. Profound variation was witnessed concerning the initiation and interval of surveillance, and risk factors taken into consideration, such as disease extent and concomitant diagnosis of primary sclerosing cholangitis (PSC). The available national and European guidelines recommend the use of chromoendoscopy in the performance of surveillance. This technique was conducted by 8% of respondents, whereas 50% conducted conventional endoscopy with random biopsies.
Conclusions: The heterogeneity in surveillance practices underlines the need for consistency among the guidelines, explicitly stated by 77% of the respondents. For this, future research on surveillance in pediatric UC is warranted, focusing on the risk of UC-associated colorectal cancer related to risk factors and optimal endoscopy techniques.
Intussusception is a common cause of acute and subacute small bowel obstruction in children, young, and older patients; however, despite increasing awareness of the condition and the number of patients diagnosed with it across all ages, its clinical and diagnostic approach remains challenging. A 17-year-old girl attended our gastroenterology outpatient department complaining of a 6-month history of recurrent right iliac fossa pain associated with nausea and vomiting at times with no past medical history of note. Initial blood tests revealed a slightly raised CRP (9.1 mg/L) and a significantly elevated fecal calprotectin (>1000 µg/g). Computed axial tomography scan of the abdomen and pelvis revealed ileocecal intussusception with no evidence of small or large bowel obstruction. On subsequent colonoscopy a 5-cm mass protruding through the ileocecal valve was identified and multiple biopsies were taken for histological analysis, which confirmed a diagnosis of Burkitt's lymphoma. The lesion was surgically resected and plans for adjuvant chemotherapy were discussed. The learning lessons to take from this case are to widen the list of differential diagnoses of unexplained recurrent abdominal pain to include intussusception and to actively rule it out with an appropriate diagnostic approach that addresses its potential malignant etiology across all ages.
Objectives: Autoimmune hepatitis and primary sclerosing cholangitis (PSC) can both be present, resulting in autoimmune sclerosing cholangitis (ASC). PSC physiopathology could be based on the cross-talk between gut microbiota and bile acids (BAs); antibiotics are an innovative therapy. This pilot study assesses metronidazole (MTZ)'s effectiveness in ASC or PSC patients according to the stage of the disease, and its effects on biochemical parameters, BA profiles, and gut microbiota.
Methods: ASC or PSC patients from Cliniques universitaires Saint-Luc's pediatric hepato-gastroenterology division were enrolled retrospectively and prospectively; both datasets were merged. MTZ was administered over at least 14 days on top of standard treatment (ursodeoxycholic acid, azathioprine, and steroids). Fecal and blood samples were collected before (T0) and at MTZ day 14 (T14). Sustained biochemical remission was defined by the reduction of transaminases (AST and ALT), gamma-glutamyl transferase (GGT), and CRP until 12 months post-MTZ.
Results: A total of 18 patients (mean age, 13.2 ± 4.5 years) were enrolled (13 ASC and 5 PSC), and divided in remission or relapse patients. CRP, AST, ALT, and GGT levels decreased post-MTZ in both groups (excepting GGT in relapse patients), with decreases between T0 and T14 being significant for AST and ALT. Relapse patients were older (P = 0.0351) and in late-disease stage, with mainly large-duct PSC (P = 0.0466). In remission patients, the mean plasma relative abundance of hydrophilic BA increased by +6.3% (P = 0.0391) after MTZ. Neither at baseline nor T14, there were significant differences in gut microbiota recorded.
Conclusion: These data are likely indicative of long-term benefits following MTZ therapy at early-stage ASC or PSC, with increased hydrophilic BA abundance. Multicenter prospective studies are needed.
Esophagitis can be attributed to several etiologies including gastroesophageal reflux disease, caustic ingestion, medication or pill induced, radiotherapy, infectious or eosinophilic disease. There are also new consumer items on the market which can cause harmful side effects, including erosive esophagitis. In this case, we present an otherwise healthy teenage male with a history of daily vape usage with a clinical presentation of odynophagia, who was subsequently diagnosed with vaping associated esophagitis. There is currently little to no data available on the occurrence of vaping-associated esophagitis, particularly in adolescents.
Introduction: Helicobacter pylori (HP) infection is associated with gastritis, peptic ulcer disease (PUD) in the stomach and duodenum, and an increased risk of gastric cancer. The risk of infection, secondary symptoms, and negative outcomes is known to be increased in low- and middle-income countries and vastly less substantial in the United States and Europe. Current North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition guidelines recommend endoscopic diagnosis and susceptibility-guided therapy, which is not reflected by current adult guidelines for therapy. In this study, we complete a single-center retrospective review of HP risk by nativity status, as well as the results of the use of standard empiric therapy in HP and PUD patients.
Methods: We retrospectively reviewed all endoscopies with patients aged 1-21 years with a known nativity status and identified all HP diagnoses. We also completed the classification of Kyoto scores and classified patients as gastritis versus PUD. Treatment records were obtained, as well as downstream documentation of the impact of empiric therapy. HP prevalence and severity were compared between non-native and native US populations.
Results: In total 332 patients were identified, with 59 HP diagnoses. However, 64 patients were immigrants, and 268 were US natives. Totally 39.1% of all immigrant patients had an endoscopically identified HP infection, compared to only 12.7% of US native patients (P < 0.01, relative risk 3.07). HP severity was worse in immigrant patients (Kyoto score 1.5 versus 0.89; P = 0.008). Empiric high-dose amoxicillin triple therapy was equally effective in reducing symptoms in gastritis versus PUD patients.
Conclusions: Immigrant patients have a substantially higher risk and severity of HP infection than US natives. Empiric therapy remains highly effective at relieving symptoms. These findings in aggregate suggest that North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition guidelines may not adequately serve non-native pediatric patients, with an additional prospective multicenter study needed to confirm. In addition, a prospective study of treatment based on stool antigen tests, as well as a larger prospective study of empiric therapy, may suggest alterations to our approach in line with recent changes to adult Gastroenterology practice.
Although the vast majority of recognized pediatric upper gastrointestinal bleeding (GIB) resolves spontaneously, gastrointestinal hemorrhage is the most common indication for urgent or emergent therapeutic endoscopy in pediatric practice. The application of hemostatic powders, including TC-325 (Hemospray, Cook Medical, Winston-Salem, NC, USA), has shown considerable impact on the control of acute bleeding, with the advantage of potentially covering an extensive area and requiring less technical expertise. We report a case of transient adherence of an esophagogastroduodenoscopy following Hemospray application in a 22-month-old with upper GIB. Our experience does not detract from the significant gains in the management of pediatric GIB from Hemospray; however, it does raise a cautionary note toward the application technique utilized.
We describe the survival of children with acute liver failure (ALF), chronic liver disease (CLD), or acute-on-chronic liver failure (ACLF) with poor access to liver transplantation (LT). A retrospective cohort study of 42 patients <18 years of age was conducted in the Hospital Civil de Guadalajara "Dr. Juan I. Menchaca". The median age was 76 months; 57.1% were female, 40.5% presented with ALF, 35.7% with CLD, and 23.8% with ACLF. Also, 38.1% (16/42) presented liver disease of unknown etiology. Death occurred in 45.2%; 14.3% were transferred to another hospital, and none received LT. Mortality in ALF, CLD, and ACLF was 76%, 0%, and 60%, respectively. In the survival analysis, within the first 20 months after diagnosis, the mortality rate was greater than 50% with ALF. The importance of having referral programs that perform liver transplantation is highlighted by the poor prognosis of the patients, despite conservative treatment.
Objectives: This study examines the prevalence of detectable gluten immunogenic peptides (GIPs) as a proxy for gluten exposure in children with celiac disease on a gluten-free diet in the United States, as estimated by gluten breakdown products excreted in urine and stool.
Methods: Urine and stool samples were collected in 3 settings (home, gastroenterology clinic, and endoscopy) for pediatric participants (ages 6-21 years old) across 2 medical centers. Commercial ELISA assays were used to quantify the GIPs in each sample.
Results: GIPs were detected in 4 out of 44 (9.1%) of stool samples and 6 out of 125 (4.8%) of urine samples provided by 84 children. These samples were collected across all settings, and most participants (70%) were asymptomatic at the time of sample collection. For the urine samples collected at the time of endoscopy, all subjects found to have persistent enteropathy had no detectable GIPs (0/12).
Discussion: GIPs provide an additional method for screening for gluten exposures in individuals with celiac disease on a gluten-free diet, and may be used across multiple settings. We found a low detection rate of GIPs in children. Our finding of undetectable GIPs in individuals with persistent enteropathy may be expected of a single determination under close observation or represent a lack of gluten exposure within the detection window. More research is needed to understand the dynamics of gluten absorption and excretion in the US pediatric population.
