Role of Device-Assisted Enteroscopy in Crohn's Disease

Crohn's Disease (CD) is a chronic inflammatory disorder of the gastrointestinal tract, posing diagnostic and management challenges due to its potential involvement of any segment from the mouth to the anus. Device-assisted enteroscopy (DAE) has emerged as a significant advancement in the management of CD, particularly for its ability to access the small intestine-a region difficult to evaluate with conventional endoscopic methods. This review discusses the pivotal role of DAE in the nuanced management of CD, emphasizing its enhanced diagnostic precision and therapeutic efficacy. DAE techniques, including double-balloon enteroscopy (DBE), single-balloon enteroscopy (SBE), and the now-withdrawn spiral enteroscopy, enable comprehensive mucosal assessment, targeted biopsies, and therapeutic interventions like stricture dilation, bleeding control, and foreign body removal. Despite its benefits, DAE carries risks such as perforation, bleeding, and pancreatitis, which require careful procedural planning and a skilled execution. The review highlights DAE's impact on reducing surgical interventions and improving patient outcomes through minimally invasive approaches, thereby enhancing the quality of life for patients with CD. Continuous improvement and research are essential in order to maximize DAE's utility and safety in clinical practice.
