摘　　要：BACKGROUND Obscure gastrointestinal(GI)bleeding is defined as persistent bleeding despite negative evaluation with both esophagogastroduodenoscopy and colonoscopy and can be secondary to small intestinal pathology.Standard endoscopy as well as push endoscopy can be a challenge in those with altered anatomy given inaccessible areas as well as perforation risk.Single and double balloon enteroscopy can be warranted in this patient population in instances of obscure GI bleed.AIM To assess the safety and diagnostic efficacy of balloon enteroscopy for obscure GI bleeding in patients with surgically altered anatomy.METHODS A search was conducted through PubMed,MEDLINE,Google Scholar,Scopus,and Embase with the key words“enteroscopy,”“obscure bleeding,”and“altered anatomy,”to identify relevant articles in English with no restricted time frame.A search within the Reference Citation Analysis database was conducted to ensure inclusion of the latest high impact articles.Study types included in the review were prospective and retrospective reviews,case series,and case reports.The reference lists of these papers were also reviewed to find further papers that were applicable.The authors extracted the data from the studies that fit inclusion criteria.Data of interest included type of study,type of procedure,and type of altered anatomy,as well as the number of patients with any diagnostic or therapeutic intervention.Data was also recorded on procedure tolerance and complications.The data was analyzed with descriptive statistics.RESULTS Our literature search yielded 14 studies that were included.There were 68 procedures performed with 61 unique patients subjected to these procedures.Forty-four(65%)of the procedures were double balloon,21(31%)were single balloon,and 3(4%)were classified as through the scope balloon assisted.The most common altered anatomy types included Gastric Bypass Roux-en-Y,Pylorus Sparing Whipple,Orthotopic Liver Transplantation with Roux-en-Y,and Gastrojejunostomy Roux-en-Y.The procedures were succ
