Abstract
Bowel preparation is necessary for a successful colonoscopy, allowing for a smooth treatment procedure and an enhanced success rate. However, inadequate bowel preparation remains common in clinical practice, and no standardized approach exists in clinical practice. Therefore, this article reviews the primary methods available for bowel preparation and discusses their application status, efficiency, safety, and the associated patient experiences. This review aims to summarize and analyze the current status of various approaches, providing valuable reference to assist healthcare professionals in making informed decisions that lead to improved outcomes, patient comfort, and patient satisfaction.
Core Tip: Effective bowel preparation is essential for a successful colonoscopy and plays a crucial role in improving its clinical success rate. However, inadequate bowel preparation remains a common issue in clinical practice, and there is currently no standardized approach to ensure optimal outcomes. This article reviews various strategies for bowel preparation before colonoscopy—including pharmacological options, dietary adjustments, exercise-based interventions, and technological advancements—to provide a scientific reference for healthcare professionals. These insights aim to support the development of individualized treatment plans that enhance patient comfort, satisfaction, and procedural efficacy.
