Growth changes after gluteen free diet in pediatric celiac patients: a literature-review.

BACKGROUND: Celiac disease is an auto-immune disorder characterized by clinical manifestations that appear in genetically predisposed subjects after gluten ingestion. In the last years, there has been a progressive change in clinical manifestations. Our aim was to evaluate the nutritional status of children with celiac disease at diagnosis and how the gluten-free diet (GFD) influences their growth. METHODS: A search on PubMed/Medline was performed using "celiac disease", "body mass index" and "children" as key words.  Medline, Scopus, PubMed publisher and Google Scholar were searched as well.  We selected clinical studies describing the nutritional status of patients before and after GFD using indicators like height, weight, BMI, skeletal age.  We excluded papers referred to adult population or in which other diseases were related to celiac disease. Also literature-reviews were excluded. RESULTS: From 1999 to 2018, 10 studies were found. Overall, 1383 patients in pediatric age were evaluated for their nutritional status at diagnosis of celiac disease and after a variable period from 1 to 17 years of GFD. Indicators considered were height, weight, BMI and skeletal age. CONCLUSIONS: the nutritional status of celiac patients at diagnosis is variable including an increasing number of overweight and obese. GFD has a beneficial impact on growth changes determining a correction of BMI distribution towards a Gaussian shape.

Endoscopic ultrasound in pediatric population: a comprehensive review of the literature.

BACKGROUND AND AIM: Endoscopic ultrasonography (EUS) with or without fine needle aspiration/biopsy (FNA/B) is a well-established diagnostic tool in adults for the evaluation and management of gastrointestinal (GI) tract disorders. Its use in children is still limited as well as literature in pediatric age is limited, although the application of EUS is now increasing. The present article aims to review the current literature about EUS indication, accuracy and safety in pediatric age. METHODS: Electronic literature searches were conducted using Pubmed, Medline, Embase, and the Cochrane Central Register of Controlled Trials using the word pediatric endoscopic ultrasound, pediatric pancreaticobiliary AND/OR EUS, pediatric EUS technique. Main patients and procedures characteristics were analyzed. The primary endpoint was the indication of EUS. Secondary endpoints were the accuracy of the technique and the incidence of complications. RESULTS: Data were extracted from 19 articles. A total of 571 patients were investigated, with a median age of 12,7 years. A total of 634 EUS procedures were performed. The majority of EUS procedures investigated the pancreaticobiliary tract (77,7%). Most studies showed a high positive impact on management with a median value of 81,7%. No major complications were reported. Five studies reported minor complications with a median value of 2%. CONCLUSIONS: EUS is safe and has a significant role in the diagnosis of pancreaticobiliary and GI diseases even in children, with a high therapeutic success. An increasing EUS utilization by pediatric gastroenterologists is expected and offering dedicated EUS training to some selected pediatric gastroenterologists might be indicated.

Applications of wireless capsule endoscopy in pediatric age: an update.

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.

Clinical approach to the patient with acute gastrointestinal bleeding.

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.

Endoscopic dilation in pediatric esophageal strictures: a literature review.

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.

Usefulness of intraoperative endoscopy in pediatric surgery: state of the art.

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.

The role of endoscopic ultrasound in children with Pancreatobiliary and gastrointestinal disorders: a single center series and review of the literature.

BACKGROUND: The role of endoscopic ultrasound (EUS) in the management of pancreatobiliary and digestive diseases is well established in adults, but it remains limited in children. The aim of this study was to evaluate the feasibility, safety, and clinical impact of EUS use in children. METHODS: This is a retrospective analysis of a prospectively acquired database of consecutive pediatric (< 18 years) patients presenting an indication for EUS for pancreatobiliary and gastrointestinal disorders. RESULTS: Between January 2010 and January 2016, 47 procedures were performed in 40 children (mean age of 15.1 ± 4.7 years; range 3-18). The majority of EUS (n = 32; 68.1%) were performed for pancreatobiliary and upper gastrointestinal pathologies, including suspected common bile duct stones (CBDs), acute biliary pancreatitis, recurrent/chronic pancreatitis, cystic pancreatic mass, recurrent hypoglycemia, duodenal polyp, gastric submucosal lesion, and perigastric abscess. In only 2 out of 18 children with suspected CBDs or acute biliary pancreatitis, EUS confirmed CBDs. EUS-guided fine needle aspiration was performed in 3 (6.4%) patients. Fifteen (31.9%) procedures were performed for lower gastrointestinal tract disorders, including suspected anal Crohn's disease, fecal incontinence, and encopresis. Overall, EUS had a significant impact on the subsequent clinical management in 87.2% of patients. CONCLUSION: The present findings were consistent with results observed in the current relevant literature and support EUS as a safe and feasible diagnostic and therapeutic tool, which yields a significant clinical impact in children with pancreatobiliary and gastrointestinal disorders.

Management of duodenal-jejunal polyps in children with peutz-jeghers syndrome with single-balloon enteroscopy.

OBJECTIVES: Children with Peutz-Jeghers syndrome (PJS) have increased risk of polyp-related complications and emergency laparotomies. The aim of the present study was to assess the efficacy and the safety of endoscopic therapy of small bowel polyps using single-balloon enteroscopy (SBE) in children affected by PJS. METHODS: Between January 2010 and December 2011, prospectively consecutive PJS children with polyps >15 mm or polyps actively bleeding previously identified using video capsule endoscopy and magnetic resonance imaging underwent therapeutic SBE. The main outcome measurements were the feasibility, the technical performance, and the safety. RESULTS: A total of 10 children (6 boys; median age 13.7 years, range 5.6-15.6) underwent 23 SBE procedures. Four patients had a history of abdominal surgery. A total of 53 polyps were removed, and 23 of them were >15 mm. The majority of polyps were found in jejunum (85%). The mean insertion depths for antegrade and retrograde approach were 200 ± 80 and 100 ± 50 cm beyond the ileal valve, respectively. The mean procedure time was 75 ± 25 minutes. Mild abdominal pain was reported after 3 procedures. In 1 patient a postpolypectomy perforation occurred. CONCLUSIONS: In conclusion, SBE is an effective endoscopic tool for treating small bowel polyps in children with PJS, and well-timed polypectomy may optimize patients' care, preventing polyp-related complications and emergency laparotomy. Further larger multicenter studies are warranted to accurately determine the safety of therapeutic SBE in children.

Cystic fibrosis and Crohn's disease: successful treatment and long term remission with infliximab.

The association of cystic fibrosis and Crohn's disease (CD) is well known, but to date, there are very few cases in the literature of patients suffering from mucoviscidosis who have required treatment with infliximab. We report the case of a 23-year-old patient suffering from cystic fibrosis and severe CD treated successfully with infliximab without any infective complications or worsening of the pulmonary disease and with a long term (2 years) complete remission.
