张小元基于“肠肛同调”思想运用“三期九法”治疗肛肠疾病经验

Zhang Xiaoyuan’s Experience in Treating Anorectal Diseases with the “Three Stages and Nine Methods” Based on the Thought of “Intestinal-Anorectal Co-Regulation”

摘要: 张小元教授认为肛肠疾病的核心病机可概括为“肠失枢转，肛络痹阻，本虚标实”，肠腑功能失调与肛周局部病变互为因果、交织为患，并据此提出“肠肛同调”诊疗思想。在此基础上，他将病程动态划分为急性期、迁延期、康复期三个阶段，创立“三期九法”分层干预体系：急性期标实突出，治以清、消、通三法祛邪为主；迁延期虚实夹杂，治以和、调、化三法燮理气血；康复期本虚为主，治以补、固、防三法培元防变。临证注重内外协同，外以枯蛇花熏洗方直达病所，内以乌梅四逆汤化裁调燮枢机，体现消补兼施、分期论治之特色。所附验案提示该体系对迁延期肛肠疾病具有较好的临床疗效，可为中医肛肠病的临床辨治提供参考。本文并溯其经典渊源与学术定位，比较当代诸家学术取向，并坦诚分析本研究之局限。

Abstract: Professor Zhang Xiaoyuan holds that the core pathogenesis of anorectal diseases can be summarized as “loss of pivot movement of the intestine, obstruction of the anorectal collaterals, and deficiency in the root with excess in the branch”, in which intestinal dysfunction and local perianal lesions act as both cause and effect and intertwine with each other. On this basis, he proposes the diagnostic and therapeutic thought of “intestinal-anorectal co-regulation” and divides the course of the disease dynamically into the acute, the protracted and the rehabilitation stage, thereby establishing a stratified intervention system known as the “Three Stages and Nine Methods”: in the acute stage, where branch excess predominates, the three methods of clearing, resolving and unblocking are used mainly to dispel pathogenic factors; in the protracted stage, where deficiency and excess are intermingled, the three methods of harmonizing, regulating and transforming are used to regulate qi and blood; and in the rehabilitation stage, where root deficiency predominates, the three methods of tonifying, securing and preventing are used to consolidate the primordial qi and prevent relapse. In clinical practice, emphasis is laid on the coordination of internal and external treatment: externally, Kushehua Fumigation-Washing Formula acts directly on the affected region, while internally, modified Wumei Sini Decoction regulates the pivot. This reflects the features of simultaneous dispersion and supplementation and of treatment according to the stage of disease. The case reported at the end suggests the favorable clinical efficacy of this system in protracted anorectal diseases, and may serve as a reference for the clinical differentiation and treatment of anorectal diseases in traditional Chinese medicine. The paper also traces its classical origins and academic position, compares the main contemporary academic approaches, and candidly discusses the limitations of the present study.
