What is a thrombosed hemorrhoid?

Hemorrhoids are enlarged vascular tissue in your lower rectum and anus. That’s the opening at the end of your large intestine through which stool leaves your body. Everyone has痔疮. They don’t cause problems unless they swell up, however. Swollen hemorrhoids can cause itching and pain around your anus that can make bowel movements uncomfortable.

A thrombosed hernia is when a blood clot forms inside a hemorrhoid. This condition isn’t dangerous, but it can be painful.

There are two types of hemorrhoids:

  • 内部痔疮在您的直肠内部。
  • 外痔are around your anus.

血栓性痔疮可能非常痛苦。如果您有一个，走路，坐下或去洗手间可能会受伤。

Other hemorrhoid symptoms include:

  • itching around your anus
  • bleeding when you have a bowel movement
  • 肿胀或肛门周围的肿块

如果您发烧以及疼痛和肿胀，您可能会有一个称为脓肿的感染区域。

您可以从直肠中静脉的压力增加中获得痔疮。这种压力的原因包括：

  • straining while you have a bowel movement, especially if you’re constipated
  • 腹泻
  • irregular bowel movements
  • 怀孕，来自婴儿的力量，在您的静脉上按下或在分娩过程中推动
  • sitting for a long period of time, such as during a long car, train, or plane trip

Doctors don’t know why some people develop blood clots in their hemorrhoids.

Hemorrhoids are very common. About每四个人中有三个will get at least one in their lifetime.

You’re more likely to get a hemorrhoid if you:

  • are constipated because you don’t get enough fiber in your diet or due to a medical condition
  • are pregnant
  • often sit for long periods of times
  • 年龄较大，因为衰老会削弱固定痔疮的组织

See your doctor if you have pain or itching around your anus, or if you bleed when you have a bowel movement. It’s important to see your doctor, because bleeding can also be a sign of cancer in the gastrointestinal (GI) tract.

你的医生will ask about your symptoms and medical history. During the exam, they may insert a gloved, lubricated finger into your rectum to feel for any lumps or growths. This is called adigital rectal exam.

If you have signs or are at risk forcolon cancer, you may need one of these exams to look deeper inside your colon.

  • 乙状结肠镜检查: The doctor inserts a thin, flexible scope with a camera at one end to view the bottom part of your colon. The scope allows your doctor to look for precancerous growths called polyps, and other changes in your colon.
  • 结肠镜检查：医生使用范围来查看结肠的整个长度。

The main treatment for a thrombosed hemorrhoid is a procedure, called an external thrombectomy, that makes a small cut in the clot and drains it. You will get local anesthesia to prevent you from feeling pain.

如果您在内部有限的话，此过程最有效three daysafter the hemorrhoid appears. It works quickly, but the clots can come back. You might still have pain after surgery.

Surgery for hemorrhoids

Less than10 percent有痔疮的人需要手术。如果您的痔疮很大，或者如果您具有外部和内部痔疮，则可能需要手术。

种类surgery for hemorrhoidsinclude:

Rubber band ligation:The doctor places a small elastic band at the base of the hemorrhoid. In a few weeks, the hemorrhoid should shrink.

痔疮切除术：该过程与凝块和血管一起去除痔疮。您可能会得到一个脊柱块，使手术区域麻木，或者在此过程中您可能在全身麻醉下睡着了。该过程比外部血栓切除术更具侵入性，并且执行时间更长，但是痔疮不太可能回来。通常仅针对最严重的痔疮来完成，因为它会导致更多的疼痛。该手术的副作用包括疼痛，尿路感染以及空排空膀胱的麻烦。

钉舌的：当您在全身麻醉下入睡时，也可以完成此过程。外科医生使用钉钉仪器将痔疮放回原处，并将其固定在那里。

The pain of thrombosed hemorrhoids should improve within 7 to 10 days without surgery. Regular hemorrhoids should shrink within a week. It may take a couple of weeks for the lump to completely go down.

您应该能够立即恢复大多数活动。在康复时，请避免强烈的运动和其他剧烈的活动。

Hemorrhoids can come back. Having hemorrhoidectomy surgery reduces the likelihood that they’ll return.

血栓性痔疮通常不会引起并发症。他们可能会非常痛苦，但是可能会流血。

有时，您的身体会从血栓痔疮中吸收凝块，而痔疮会在一两个星期内自行改善。如果您在出现血栓性痔疮的三天内进行了手术，则可以缓解疼痛和其他症状。
