This paper introduces Professor Lu Jin’gen’s clinical experience in the treatment of outlet obstructive constipation exemplified by the constipation cases due to anismus, pelvic floor relaxation (PFR), puborectal muscle hypertrophy (PRMH) and rectocele. In the clinic, Professor Lu does not advocate the over-use of purgative medicinals such as Dahuang (Rhei Radix et Rhizoma), Luhui (Alo) and Fanxieye (Sennae Folium), etc. as he believes that this type of constipation should be diagnosed with the combination of disease differentiation and TCM pattern identification and he proposes that invigorating qi, relieving constipation and unblocking collaterals should be taken as the major method. A proved case is attached for the supportive illustration.
