Аннотация
INTRODUCTION: Anorectal disorders, such as chronic constipation and fecal incontinence, significantly impact patients' quality of life. Accurate diagnosis is essential for effective treatment, and the balloon expulsion test (BET) has emerged as a simple yet valuable tool in evaluating anorectal function. Despite its simplicity, variations in technique and interpretation have led to ongoing debates regarding its diagnostic precision. To support this review, a PubMed search was conducted using the terms balloon, expulsion, test, evacuation, and disorders, focusing on the most relevant articles published over the past 25 years.
AREAS COVERED: This review explores the evolution of the BET, highlighting its role in diagnosing defecatory disorders. It examines various methodologies, standardization efforts, and the test's sensitivity and specificity compared to other diagnostic modalities like anorectal manometry and defecography.
EXPERT OPINION: The balloon expulsion test remains a cornerstone in the functional assessment of anorectal disorders due to its simplicity, cost-effectiveness, and accessibility. However, standardized protocols are essential to improve diagnostic accuracy and reproducibility. Future research should focus on refining BET techniques and integrating them with advanced diagnostic tools to enhance patient outcomes and guide personalized treatment strategies.
