| 1 | Pediatric gastrointestinal bleeding: Perspectives from the Italian Society of Pediatric Gastroenterology显示文摘There are many causes of gastrointestinal bleeding(GIB) in children, and this condition is not rare, having a reported incidence of 6.4%. Causes vary with age, but show considerable overlap; moreover, while many of the causes in the pediatric population are similar to those in adults, some lesions are unique to children. The diagnostic approach for pediatric GIB includes definition of the etiology, localization of the bleeding site and determination of the severity of bleeding; timely and accurate diagnosis is necessary to reduce morbidity and mortality. To assist medical care providers in the evaluation and management of children with GIB, the 'Gastro-Ped Bleed Team' of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition(SIGENP) carried out a systematic search on MEDLINE via Pub Med(http://gffzz16a62c593b5540ceh60wqfvkpn6f56c0o.ffgz.tsg.suse.edu.cn/pubmed/) to identify all articles published in English from January 1990 to 2016; the following key words were used to conduct the electronic search: 'upper GIB' and 'pediatric' [all fields]; 'lower GIB' and 'pediatric' [all fields]; 'obscure GIB' and 'pediatric' [all fields]; 'GIB' and 'endoscopy' [all fields]; 'GIB' and 'therapy' [all fields]. The identified publications included articles describing randomized controlled trials, reviews, case reports, cohort studies, casecontrol studies and observational studies. References from the pertinent articles were also reviewed. This paper expresses a position statement of SIGENP that can have an immediate impact on clinical practice and for which sufficient evidence is not available in literature. The experts participating in this effort were selected according to their expertise and professional qualifications. | Claudio Romano Salvatore Oliva Stefano Martellossi Erasmo Miele Serena Arrigo Maria Giovanna Graziani Sabrina Cardile Federica Gaiani Gian Luigi de'Angelis Filippo Torroni | 2017 | World Journal of Gastroenterology2017，23，8： | 12 |
