关键区别 - 堆与瘘管
桩或内部痔疮是多种多样的hemorrhoidswhich can be defined as the varicosities of the tributaries of superior rectal vein covered by a mucous membrane. A fistula is a pathological track that is lined with granulation tissue orepitheliumthat connects two epithelial surfaces. In a morphological sense,可以将桩视为囊没有向外部开放的囊。但是瘘管在任一端都有两个空缺。这是这两个病理病变之间的关键区别。

什么是桩？
堆are varicosities of the tributaries of superior rectal vein covered by a mucous membrane; these are also known as internal hemorrhoids. The tributaries that lie in 3’, 7’ and 11’ positions when viewed in the lithotomy position are particularly vulnerable to get hemorrhoids. The superior rectal vein is valveless and cannot control the flow of blood through it. In addition, it is located in the most dependable area of thecapillarynetwork of the anal canal. These contributory factors further increase the vulnerability of this region to get hemorrhoids.
Figure 02: Piles
There are three stages of internal hemorrhoids.
- First degree – piles remain inside the anal canal.
- Second degree – piles extrude from the anal canal during the defecation but later return to their normal position.
- 三度 - 堆在肛管外面。
Internal hemorrhoids do not cause any pain because they are innervated by autonomic afferent nerves.
原因
- Family history of hemorrhoids
- 一个y disease that causes portal hypertension
- Chronic constipation
症状
- 堆are usually painless
- Per rectal bleeding
- pruritus
什么是瘘管？
瘘管是一条病理性轨道，衬有连接两个上皮表面的肉芽组织或上皮。一个anal fistula is a similar connection between thelumen肛管或直肠和毛皮皮。一个abscessthat develops in the inter-sphincteric space can burst in two directions if kept untreated, creating the characteristic track with two openings. These lesions do not heal spontaneously because, mucus is forced out through the tract during defecation, inhibiting any damage repairing mechanisms.

Associated Conditions
高级瘘管的发生极为罕见。这些高级瘘管从直肠到毛皮皮肤，位于厌食环上方。因此，粪便始终通过皮肤表面的开口污染衣服。但这不会发生在位于肛门直肠环下方的低级瘘管中。
Presentation
- 成年人比孩子更有可能获得瘘管
- 蠕虫脓肿的史
- Presence of a watery purulent discharge
- It is important to look for the symptoms of inflammatory bowel diseases
- Usually, the local lymph nodes are not enlarged
Sigmoidoscopy and proctoscopy can be used to exclude the possibility of Crohn’s disease or ulcerative colitis.

概括– Piles vs Fistula
瘘管是一条病理性轨道，衬有连接两个上皮表面的肉芽组织或上皮。The varicosities of the tributaries of superior rectal vein covered by a mucous membrane are known as internal hemorrhoids or piles. The absence of any openings to outside in the piles is the key difference between piles and fistula, which helps us to identify the two conditions separately.
