论述说：肠痈是由于愤怒没有节制，忧虑思虑过度，导致肠胃虚弱，寒热失调，邪热相互交攻，致使营卫之气相互干扰，血液败坏浑浊，流渗入肠道，不能正常传导，积聚凝结成痈肿，津液腐败化生，变成脓汁。其症状表现为少腹部坚硬胀满，按压时内部疼痛，有时脓液从脐中流出，有时大便排出脓血，应当紧急治疗，否则邪毒内攻，腐蚀肠胃，就无法挽救了。诊察其脉象洪大数急的，说明脓已经形成；如果脉象迟而紧，虽然脓尚未成熟，但已有瘀血存在。

Commentary states: Changyong (Intestinal Abscess) arises from uncontrolled anger, excessive worry and overthinking, leading to weakness of the intestines and stomach, disharmony of cold and heat, and mutual attack of pathogenic heat. This causes interference between Ying (Nutritive Qi) and Wei (Defensive Qi), resulting in blood becoming turbid and degenerated. The fluid flows into the intestines, fails to conduct normally, accumulates, condenses, and forms an abscess. Body fluids rot and transform into pus. The manifestations include hardness and fullness in the lower abdomen, internal pain upon pressure, sometimes pus discharging from the umbilicus, or pus and blood passing in the stool. It is imperative to treat it urgently; otherwise, pathogenic toxins will attack internally, corroding the intestines and stomach, rendering it incurable. Palpation reveals a洪数 (Hong-Shu, surging and rapid) pulse indicates that pus has already formed. If the pulse is迟紧 (Chi-Jin, slow and tight), although pus has not yet matured, blood stasis is already present.
