Single Balloon Enteroscopy Versus Push Enteroscopy for Small Bowel Bleeding Assessment: A Systematic Review and Meta-Analysis

Background: Until recently, the small bowel was considered to be inaccessible using conventional endoscopy techniques. In 2001, the balloon enteroscopy system to examine the small bowel was introduced. Single balloon enteroscopy versus push enteroscopy for small bowel diagnostics are 2 types of commonly used balloon-assisted enteroscopic techniques for "deep enteroscopy. Objective: To perform a systematic review and meta-analysis to assess the efficacy and safety of single balloon enteroscopy versus push enteroscopy for small bowel bleeding assessment.
Methods: A systematic search strategy was performed to determine the related literature. Initially, the objectives of review were identified: specifically, impact of single balloon enteroscopy vs push enteroscopy for small bowel diseases. These databases were searched for articles published in English in data bases [Pubmed – Google Scholar- Science direct] and Boolean operators (AND, OR, NOT) had been used such as [Impact AND Single Balloon AND Push AND Small Bowel OR GIT] and in peer-reviewed articles between 2000 and 2021.
Conclusion: Our meta-analysis indicated that both single balloon technique and push enteroscopy techniques are safe procedures with rare complications, with the single balloon technique having higher diagnostic and therapeutic yields compared with the push technique.
