盆底功能障碍背景下直肠内脱垂的分级标准及诊疗策略
Standardized Criteria and Management Strategies for Internal Rectal Prolapse in the Context of Pelvic Floor Dysfunction
摘要
Abstract
Pelvic floor dysfunction(PFD)is a clinical syndrome mainly characterized by urinary incontinence,defecation dysfunction,and pelvic organ prolapse,which significantly affects the quality of patients'life.Internal rectal prolapse(IRP),as an important component of PFD,is closely related to the integrity of the pelvic floor support structure in terms of its grading.Current evidence shows that the degeneration of the pelvic floor support structures and the dysfunction of the levator ani muscle caused by PFD are the key driving factors for the occurrence and development of IRP.The grading of IRP is significantly correlated with the degree of pelvic floor injury.High-grade IRP(Grades Ⅲ-Ⅳ)is often accompanied by severe pelvic floor anatomical and functional abnormalities.Dynamic magnetic resonance defecography(DMRD)and high-resolution anorectal manometry(HR-ARM)are the key tools for objective grading and functional evaluation.In terms of treatment,low-grade IRP responds well to pelvic floor muscle training(PFMT),while high-grade IRP often requires surgical intervention.Currently,there is still a lack of a unified grading standard and support from prospective cohort studies in this field.In the future,efforts should be made to construct a standardized grading system through multi-center collaboration,integrating radiomics and artificial intelligence technologies to promote precision diagnosis and treatment.关键词
