肠痈这种病，是由于寒温调节不当、喜怒情绪无常，导致邪气与营卫之气相互干扰并停留在肠道内。遇到热邪侵袭后，血气郁结积聚，形成肿块。其症状表现为小便频数且类似淋证，脉象迟而紧的，说明脓液尚未形成；病情严重的会出现腹部胀大，翻身转动时可听到水声，或者肚脐周围生疮，破溃后流出脓液，或者自行排出脓血。对此应当紧急治疗。又有说法称，大便排出脓血，类似于赤白痢疾的，就是肠痈。突然患上肠痈的人，治疗时往往有很多错误。如果寸口脉滑而数，滑脉主实证，数脉主热证；滑脉反映营气状况，数脉反映卫气状况。若热气上升，遇热则营卫相干，血液单独疲惫，出现小腹痞满，小便困难，出汗或再次恶寒，这是脓液已经形成的表现。假如脉象迟紧，则是瘀血凝聚，血液下行则病愈；脓液成熟则牵引出白色脓液。此外，凡见浮数脉，本应发热却反而感到阵阵恶寒，若有固定疼痛部位的，应当积有脓液。脉象滑涩相搏，是肠痈吐脓的表现。

Intestinal abscess (Chang Yong) arises from improper regulation of cold and warmth, and irregularity in joy and anger, causing pathogenic factors to interfere with Ying and Wei Qi (Defensive and Nutritive Qi) and remain within the intestines. Upon encountering heat, Qi and blood stagnate and accumulate, forming a mass. Symptoms include frequent urination resembling strangury (Lin syndrome). A slow and tight pulse indicates that pus has not yet formed; severe cases present with abdominal distension, audible fluid sounds when turning over, or sores around the umbilicus that rupture and discharge pus, or spontaneous passage of pus and blood. Urgent treatment is required. It is also stated that passing pus and blood in stool, resembling dysentery with red and white discharge, constitutes intestinal abscess. Patients suddenly afflicted with intestinal abscess are often treated incorrectly. If the Cun-kou pulse is slippery and rapid, slipperiness indicates excess, while rapidity indicates heat; slipperiness reflects the state of Ying Qi, and rapidity reflects the state of Wei Qi. If heat rises and interferes with Ying and Wei due to heat, blood becomes exhausted alone, presenting with fullness and stuffiness in the lower abdomen, difficulty in urination, sweating, or recurrent aversion to cold, indicating that pus has already formed. If the pulse is slow and tight, it signifies coagulation of stasis; if blood passes downward, the disease resolves; mature pus draws out white discharge. Furthermore, floating and rapid pulses typically accompany fever, but if there is instead a sensation of shivering aversion to cold and fixed pain, pus accumulation should be suspected. A pulse that is both slippery and choppy indicates intestinal abscess with expectoration of pus.
