RESUMEN
BACKGROUND AND AIMS: Upper 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. METHODS: Conducted 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. RESULTS: A 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. CONCLUSIONS: Pediatric 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.
RESUMEN
Motorized spiral enteroscopy (MSE) is the latest advance in device-assisted enteroscopy. Adverse events related to MSE were discussed in a recent large systematic review and meta-analysis and were directly compared with those of balloon enteroscopy in a case-matched study and a randomized controlled trial. Following the real-life application of MSE, an unexpected safety issue emerged regarding esophageal injury and the technique has been withdrawn from the global market, despite encouraging results in terms of diagnostic and therapeutic yield. We conducted an Italian multicenter real-life prospective study, which was prematurely terminated after the withdrawal of MSE from the market. The primary goals were the evaluation of MSE performance (both diagnostic and therapeutic) and its safety in routine endoscopic practice, particularly in the early phase of introduction in the endoscopic unit. A subanalysis, which involved patients who underwent MSE after unsuccessful balloon enteroscopy, demonstrated, for the first time, the promising performance of MSE as a rescue procedure. Given its remarkable performance in clinical practice and its potential role as a backup technique following a previously failed enteroscopy, it may be more appropriate to refine and enhance MSE in the future rather than completely abandoning it.

BACKGROUND: Cyclic Vomiting Syndrome (CVS) is a rare functional gastrointestinal disorder, which has a considerable burden on quality of life of both children and their family. Aim of the study was to evaluate the diagnostic modalities and therapeutic approach to CVS among Italian tertiary care centers and the differences according to subspecialties, as well as to explore whether potential predictive factors associated with either a poor outcome or a response to a specific treatment. METHODS: Cross-sectional multicenter web-based survey involving members of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) and Italian Society of Pediatric Neurology (SINP). RESULTS: A total of 67 responses were received and analyzed. Most of the respondent units cared for less than 20 patients. More than half of the patients were referred after 3 to 5 episodes, and a quarter after 5 attacks. We report different diagnostic approaches among Italian clinicians, which was particularly evident when comparing gastroenterologists and neurologists. Moreover, our survey demonstrated a predilection of certain drugs during emetic phase according to specific clinic, which reflects the cultural background of physicians. CONCLUSION: In conclusion, our survey highlights poor consensus amongst clinicians in our country in the diagnosis and the management of children with CVS, raising the need for a national consensus guideline in order to standardize the practice.

Celiac disease (CD) is an immune-mediated disorder initiated by the ingestion of gluten in genetically predisposed individuals. Recent data shows that changes in the gut microbiome composition and function are linked with chronic inflammatory diseases; this might also be the case for CD. The main aim of this manuscript is to discuss our present knowledge of the relationships between gut microbiota alterations and CD and to understand if there is any role for probiotics in CD therapy. PubMed was used to search for all of the studies published from November 2009 to November 2019 using key words such as "Celiac Disease" and "Microbiota" (306 articles), "Celiac Disease" and "Gastrointestinal Microbiome" (139), and "Probiotics" and "Celiac Disease" (97 articles). The search was limited to articles published in English that provided evidence-based data. Literature analysis showed that the gut microbiota has a well-established role in gluten metabolism, in modulating the immune response and in regulating the permeability of the intestinal barrier. Promising studies suggest a possible role of probiotics in treating and/or preventing CD. Nevertheless, human trials on the subject are still scarce and lack homogeneity. A possible role was documented for probiotics in improving CD-related symptoms, modulating the peripheral immune response and altering the fecal microbiota, although the results were not consistent in all of the studies. No evidence was found that probiotic administration might prevent CD onset. Knowledge of the role of intestinal bacteria in the development of CD opens new possibilities for its treatment through probiotic administration, even though further studies are needed to better clarify whether probiotics can help treat or prevent the disease and to define which probiotics to use, at what dose and for how long.

RATIONALE: Triple-A syndrome, or Allgrove syndrome (AS), is a rare autosomal recessive disorder characterized by the alacrimia, achalasia, and adrenal insufficiency triad. Alacrimia usually starts at early infancy, while achalasia and adrenal insufficiency appear later during childhood or adulthood. Some patients may also present with the so-called Double-A syndrome (i.e., alacrimia and achalasia, or alacrimia and adrenal insufficiency); adrenal insufficiency usually represents a life-threatening event due to severe hypoglycemia. Many patients may also present other associated manifestations, such as neurological disorders. We describe, here, 2 sisters of non-consanguineous parents. PATIENT CONCERNS: An 8-year-old girl was admitted to the Pediatric Care Unit of Parma after an episode characterized by seizure with loss of consciousness and generalized hypertonia lasting a few minutes. Her sister, a 6-year-old girl, presented with recurrent episodes of vomiting and failure to thrive. DIAGNOSES: Both children were investigated by laboratory tests, esophagogastroduodenoscopy, and imaging. The first patient had the complete triad of AS (alacrimia, achalasia, adrenal insufficiency), while the second one presented only alacrimia and achalasia. Both resulted from a mutation in the achalasia, addisonianism, alacrimia syndrome gene. INTERVENTIONS: Both patients were treated with oral hydrocortisone for Addison disease, and with artificial tears in the first case. After many pneumatic endoscopic dilations and therapy with nifedipine, both patients underwent surgical Heller myotomy for achalasia. OUTCOMES: A rapid and favorable recovery to normal diet and with improvement of growth parameters was obtained. These cases are also compared with the literature data, reported in a brief review. LESSONS: AS is a rare multisystemic disorder. The longer diagnosis is delayed, the greater extent to which this syndrome may be life-threatening, mainly because of hypoglycemia due to adrenal insufficiency. In AS, the red-flag symptom of alacrimia should instigate investigation for achalasia, Addison disease, and achalasia, addisonianism, alacrimia syndrome gene mutation.

Celiac disease is a chronic immune-mediated enteropathy triggered by exposure to dietary gluten in genetically predisposed individuals. Many genes involved in the pathogenesis have been identified and a crucial role is known to be played by the Human Leukocyte Antigen (HLA) system. The main determinants for genetic susceptibility are HLA-DQA1 and HLA-DQB1 genes encoding for HLA-DQ2 and HLA-DQ8 molecules, carried by almost all patients affected. However, since HLA-DQ2 and HLA-DQ8 heterodimers explain almost 40% of the disease heritability, HLA typing should not be applied in diagnosis, but exclusively to clarify uncertain diagnoses, considering its negative predictive value.

Chronic autoimmune thyroid disease or Hashimoto thyroiditis (HT) and Graves-Basedow disease (GD) are the main autoimmune thyroid diseases in pediatric age. Both are characterized by the production of anti-thyroid antibodies, by an infiltration of autoreactive B and T lymphocytes into the thyroid parenchyma and by alterations in thyroid function (hyperthyroidism in GD, normal function or subclinical hypothyroidism in HT with possible evolution towards manifest hypothyroidism). Celiac disease (CD) is a systemic autoimmune disease caused by gluten ingestion in genetically predisposed subjects, its prevalence is around 1% in Western Countries. It presents with a pathognomonic enteropathy, a variety of clinical manifestations, positivity for specific antibodies, positivity for typical haplotypes HLA DQ2/DQ8. The clinical manifestations may vary among four types: typical, atypical, silent and latent. Diagnosis can be made in presence of specific histopathologic findings in duodenal biopsies and antibodies positivity. Celiac disease is associated to various endocrine autoimmunities such as thyropathies, diabetes mellitus type 1, Addison disease, multiendocrine syndromes. The most frequent associated thyropaties are HT and GD. The present review aims to explore the associations between thyropathies and celiac disease in pediatric age.

BACKGROUND: The small bowel has often been considered the mysterious "black hole" of the gastrointestinal tract. With regards to this, the development of the wireless capsule endoscopy (WCE) has represented a turning point. It is a non-invasive technique, enabling an excellent visualization of the small bowel (SB) mucosa without the use of radiation. The WCE was approved by the Food and Drug Administration (FDA) in 2001 for adults and in 2004 for children. The aim of the present review is to provide an update on indications, diagnostic yield, safety and limitations of WCE in children. Even though literature regarding the use of WCE in pediatric age is more limited than in adults, WCE is a useful and safe diagnostic tool for the exploration of the small bowel also in children. The indications for WCE are similar at any age, however the main indication in children is Crohn's disease (CD), while in the adults is the research of SB bleeding. The main limitation in pediatric age is the possibility for younger children to swallow the capsule. WCE in pediatric is a rapidly advancing technology and has the potential to further transform the evaluation and management of SB disease.

Fluorouracil-based preoperative chemoradiotherapy represents a standard option for the treatment of locally advanced rectal cancer. Randomized clinical trials have shown that fluorouracil concomitant to preoperative radiation enhances tumor shrinkage (with 10% to 15% of the patients showing a complete pathological tumor response) compared with preoperative radiation alone. A high response rate is of clinical importance in rectal cancer, since patients who achieve a complete pathological response may experience improved long-term survival. Adding oxaliplatin to fluorouracil-based preoperative chemoradiotherapy has no effect on response of the primary rectal tumor and single-agent fluoropyrimidine remains the standard chemotherapy in this setting. Despite novel biological insights and therapeutic advances, little is known about potential biological markers able to predict pathological tumor response before treatment and to subsequently impact patients' prognosis. This review focuses on the current available data on main molecular markers and molecular subtypes and the possible upcoming introduction of such analyses in the clinical setting.

Gastrointestinal bleeding (GIB) is a very common condition at all ages, with high rates of morbidity and mortality, especially in case of acute presentation. The optimal management of acute GIB requires a timely overview of vital signs and clinical presentation to stabilize the patient if necessary and set up the most adequate diagnostic and therapeutic approach, based on the suspected etiology. Endoscopy plays a major role both in diagnosis and treatment of acute GIB, as allows the application of several hemostasis techniques during the diagnostic session, which should preferably be performed within 24 hours from the acute event. The hemostasis technique should be chosen based on type, etiology of the bleeding and the operator preference and expertise. Nevertheless, several challenging cases need the cooperation of radiology especially in the diagnostic phase, and even in the therapeutic phase for those bleedings in which medical and endoscopic techniques have failed. Imaging diagnostic techniques include mainly CT angiography, scintigraphy with labeled erythrocytes and arteriography. This last technique plays also a therapeutic role in case arterial embolization is needed. Only those patients in which the previous techniques have failed, both in diagnosis and treatment, are candidates for emergency surgery.

BACKGROUND: Esophageal strictures in pediatric age are a quite common condition due to different etiologies. Esophageal strictures can be divided in congenital, acquired and functional. Clinical manifestations are similar and when symptoms arise, endoscopic dilation is the treatment of choice. Our aim was to consider the efficacy of this technique in pediatric population, through a wide review of the literature. METHOD: A search on PubMed/Medline was performed using "esophageal strictures", "endoscopic dilations" and "children" as key words. Medline, Scopus, PubMed publisher and Google Scholar were searched as well. As inclusion criteria, we selected clinical studies describing dilations applied to all type of esophageal strictures in children. Papers referred to single etiology strictures dilations or to adult population only were excluded, as well as literature-review articles. RESULTS: We found 17 studies from 1989 to 2018. Overall, 738 patients in pediatric age underwent dilation for esophageal strictures with fixed diameter push-type dilators (bougie dilators) and/or radial expanding balloon dilators. Severe complications were observed in 33/738 patients (4,5%) and perforation was the most frequent (29/33). Conversion to surgery occurred only in 16 patients (2,2%). CONCLUSIONS: Endoscopic dilation is the first-choice treatment of esophageal strictures, it can be considered a safe procedure in pediatric age. Both, fixed diameter push-type dilators and radial expanding balloon dilators, showed positive outcomes in term of clinical results and cases converted to surgery. However, it's essential to perform these procedure in specialized Centers by an experienced team, in order to reduce complications.

Usually, non-invasive tests are the first methods for diagnosing Helicobacter pylori (HP) infection. Among these, serological test, stool antigen research and urea breath test are the most used. Antibodies anti-HP are not recommended in low prevalence population, moreover they cannot reveal an ongoing infection, but they only prove a contact with the bacterium. Also, they can persist for a long time after the eradication of the infection, therefore, they should not be used to verify the success of eradication therapy. Stool antigen research and Urea Breath Test (UBT) are useful both in diagnosis and during follow-up after eradication treatment. The stool antigen test is cheaper than Urea breath test with similar sensitivity and specificity. Non-invasive tests are not able to diagnose the associated complications to HP infection.

INTRODUCTION: Intraoperative endoscopy is a procedure that supports open and laparoscopic surgery, helping the surgeon to identify the presence of endoluminal gastrointestinal lesions which need to be treated, with a correct diagnosis and an adequate therapy. MATERIAL AND METHODS: A search on PubMed was performed using "intraoperative esophagoscopy", "intraoperative duodenoscopy", and "intraoperative enteroscopy" as Mesh terms. The applied exclusion criteria were: papers written before 2000, not concerning pediatric or gastrointestinal pathology, literature-review articles, language different from English. RESULTS: Sixteen studies from 2000 to 2018 were included. Overall, 1210 patients were treated. Different pathologies were considered. Complications were observed in a range of 0.3-14%. The most frequent complications were perforation, bleeding and mucosal tear. Mortality ranged between 0.7% and 1,2%. CONCLUSION: Intraoperative endoscopy is an indispensable tool for gastrointestinal surgery. In the hands of experienced endoscopists, intraoperative endoscopy can be performed safely, in time-efficient manner, facilitating diagnosis and treatment.

Percutaneous endoscopic gastrostomy (PEG) has become a mainstay in providing enteral access for patients with obstructive head, neck and esophageal tumors. Tumor cell implantation is a rare complication in patients with aerodigestive cancers, who have undergone PEG tube placement. The objective of this review is to determine the incidence and contributing risk factors leading to the implantation of metastases into the abdominal wall following PEG placement. A comprehensive review of the literature in PUBMED (2008-2018) was performed. The literature search revealed reports of more than 50 cases of abdominal wall metastases after PEG placement. As most of these studies were case reports, the exact rate of metastasis remains unknown. Generally pharyngoesophageal location of primary cancer (100%), squamous cell histology (98%), poorly differentiated tumor cells (92%), advanced pathological stage (97%), and large primary cancer size were identified as strong risk factors for the development of stomal metastasis. Abdominal wall metastases following PEG placement are a rare but serious complication in patients with head and neck malignancy.

BACKGROUND: Non-invasive methods are advisable for the detection of Helicobacter pylori-related chronic gastritis in pediatric patients. Serum pepsinogens I and II (sPGII and sPGII), gastrin-17 (G-17) and anti-H. pylori antibodies (IgG-Hp) have been proposed as a 'serological gastric biopsy'. AIM: To assess H. pylori infection and to evaluate gastric mucosa status in a pediatric population by means of serological parameters such as sPGI, sPGII, G-17 and IgG-Hp. METHODS: 45 consecutively children evaluated for upper gastrointestinal symptoms were analyzed. All children were submitted to upper gastrointestinal endoscopy with biopsies. Serum samples were analyzed for IgG-Hp, sPGII, sPGI and G-17 (Biohit, Helsinki, Finland). RESULTS: 18 children had H. pylori-related mild or moderate non-atrophic chronic gastritis. They presented significantly higher mean levels of sPGII and of IgG-Hp than negative ones, either under or up to 10 years. sPGI showed significantly increased levels in H. pylori-positive patients only over 10 years. G-17 levels were not different between H. pylori-positive and -negative ones. The best cut-offs of IgG-Hp, sPGII and of product IgG-Hp x sPGII, to identify H. pylori infection, were 30 IU/l, 9 microg/l, and 241 IU/l x microg/l, respectively. The product IgG-Hp x sPGII identified H. pylori infection with a 100% sensitivity, 92% specificity, 90% positive predictive value and 100% negative predictive value. IgG-Hp and IgG-Hp showed a correlation (r = 0.94; p < 0.001). CONCLUSIONS: Combined analysis of sPGII and IgG-Hp antibody levels could be recommended as a non-invasive panel for the assessment of H. pylori-related histological alterations of gastric mucosa in childhood.

BACKGROUND: Celiac disease (CD) is an immune-mediated enteropathic condition triggered in genetically susceptible individuals by the ingestion of gluten. Although common in Europe, CD is thought to be rare in the United States, where there are no large epidemiologic studies of its prevalence. The aim of this study was to determine the prevalence of CD in at-risk and not-at-risk groups in the United States. METHODS: Serum antigliadin antibodies and anti-endomysial antibodies (EMA) were measured. In EMA-positive subjects, human tissue transglutaminase IgA antibodies and CD-associated human leukocyte antigen DQ2/DQ8 haplotypes were determined. Intestinal biopsy was recommended and performed whenever possible for all EMA-positive subjects. A total of 13 145 subjects were screened: 4508 first-degree and 1275 second-degree relatives of patients with biopsy-proven CD, 3236 symptomatic patients (with either gastrointestinal symptoms or a disorder associated with CD), and 4126 not-at-risk individuals. RESULTS: In at-risk groups, the prevalence of CD was 1:22 in first-degree relatives, 1:39 in second-degree relatives, and 1:56 in symptomatic patients. The overall prevalence of CD in not-at-risk groups was 1:133. All the EMA-positive subjects who underwent intestinal biopsy had lesions consistent with CD. CONCLUSIONS: Our results suggest that CD occurs frequently not only in patients with gastrointestinal symptoms, but also in first- and second-degree relatives and patients with numerous common disorders even in the absence of gastrointestinal symptoms. The prevalence of CD in symptomatic patients and not-at-risk subjects was similar to that reported in Europe. Celiac disease appears to be a more common but neglected disorder than has generally been recognized in the United States.

The eradication therapy of Helicobacter pylori (H. pylori) infection is still a challenge for gastroenterologists. One of the main causes of failure in H. pylori eradication is the antibiotic resistance mainly to clarithromycin. Culture from biopsies is maybe the most used method among the antimicrobial susceptibility techniques. In this study, we compared the antimicrobial susceptibility changes in children with H. pylori infection over 13 years and we confirmed that clarithromycin resistance has been increased (16% versus 26%) though with no statistically signficant value. Therefore, clarithromycin should not be used in empiric treatment of H. pylori eradication therapy in children, but its use should be limited only to children with known antimicrobial susceptibility. On the other hand, metronidazole resistance has decreased over this time period in statistically significant manner (56% versus 33%, p = 0.014). Furthermore, ampicillin resistance has been confirmed to be very rare (3% versus 0%) in children with H. pylori infection. In conclusion, in H. pylori infection, if we do not know the antibiotic susceptibility of patients, we should recommend an eradication therapy based on the local distribution of antibiotic resistance rates trying to limit the therapeutic failures.
RESUMEN
Wireless capsule endoscopy is a new diagnostic technique used especially for investigating the entire small bowel. Recent studies have demonstrated its superior ability to detect and evaluate small bowel lesions compared to other radiological examinations. Performing video capsule endoscopy is regarded as contraindicated when an intestinal occlusion is documented. We present a case of hidden intestinal bleeding which underwent wireless capsule endoscopy and was treated successfully despite documented ileal stenosis.

AIM: To evaluate short- and long-term efficacy of endoscopic balloon dilation in a cohort of consecutive patients with symptomatic Crohn's disease (CD)-related strictures. METHODS: Twenty-six CD patients (11 men; median age 36.8 year, range 11-65 years) with 27 symptomatic strictures underwent endoscopic balloon dilation (EBD). Both naive and post-operative strictures, of any length and diameter, with or without associated fistula were included. After a clinical and radiological assessment, EBD was performed with a Microvasive Rigiflex through the scope balloon system. The procedure was considered successful if no symptom reoccurred in the following 6 mo. The long-term clinical outcome was to avoid surgery. RESULTS: The mean follow-up time was 40.7 ± 5.7 mo (range 10-94 mo). In this period, forty-six EBD were performed with a technical success of 100%. No procedure-related complication was reported. Surgery was avoided in 92.6% of the patients during the entire follow-up. Two patients, both presenting ileocecal strictures associated with fistula, failed to respond to the treatment and underwent surgical strictures resection. Of the 24 patients who did not undergo surgery, 11 patients received 1 EBD, and 13 required further dilations over time for the treatment of relapsing strictures (7 patients underwent 2 dilations, 5 patients 3 dilations, and 1 patient 4 dilations). Overall, the EBD success rate after the first dilation was 81.5%. No difference was observed between the EBD success rate for naive (n = 12) and post-operative (n = 15) CD related strictures (P > 0.05). CONCLUSION: EBD appears to be a safe and effective procedure in the therapeutic management of CD-related strictures of any origin and dimension in order to prevent surgery.
