What Is Enteroscopy?

肠镜检查是一种帮助您的医生在消化系统中发现和治疗问题的程序。在肠镜检查中，您的医生将带有附件的薄柔性管插入到您的身体中。这称为内窥镜。内窥镜通常有一个或两个气球。气球可以膨胀，以帮助您的医生接近食管，胃和小肠部分的仔细观察。您的医生可以在内窥镜上使用镊子或剪刀，以去除组织样品进行分析。

肠镜检查也称为：

  • double balloon enteroscopy
  • double bubble
  • 胶囊肠镜检查
  • 推动和拉动肠镜检查

两种类型的肠镜检查是上下和较低的。在上肠镜检查中，内窥镜插入口中。在较低的肠镜检查中，内窥镜插入直肠。所执行的肠镜检查类型取决于医生试图诊断的问题类型。您的医生会提前通知您需要的类型。

肠镜检查makes it possible to diagnose or evaluate diseases within the body without making an incision. It’s commonly used to detect problems in the small intestine or stomach. Your doctor may recommend enteroscopy if you have any of the following:

  • 高白细胞计数
  • 小肠中的肿瘤
  • 被封闭的肠道段落
  • 异常胃肠道出血
  • 辐射治疗肠道损伤
  • 无法解释的严重腹泻
  • unexplained malnutrition
  • 异常X射线结果

Your doctor will give you instructions on how to prepare for the procedure. Make sure to follow them carefully. You may need to:

  • stop taking aspirin or other blood-thinning medications
  • avoid solid foods and milk after 10 p.m. the night before the procedure
  • 只有饮料清除液体的过程
  • 在程序前至少四小时避免所有液体

一个小肠镜是一种门诊手术,means that you can go home the same day as the procedure. It usually takes between 45 minutes and two hours to complete.

根据所执行的类型肠镜检查，您的医生将完全稳定或给您药物以帮助您放松。这些药物将通过手臂中的静脉施用。

During the procedure, your doctor will record a video or take pictures. These can be reviewed in more detail after the procedure is done. Your doctor may also take tissue samples or remove existing tumors. The removal of any tissue or tumor won’t cause any pain.

Depending on the type of problem you’re having, your doctor will perform either an upper enteroscopy or a lower enteroscopy. An upper enteroscopy allows your doctor to view and treat the upper part of the digestive system. A lower enteroscopy allows your doctor to view and treat the lower part.

Upper Enteroscopy

在用喉咙麻木后，你的医生会把内窥镜插入口腔，逐渐通过食管逐渐缓解它，然后进入你的胃和上消化道。在这部分过程中，您可能会有压力或丰满的感觉。

Throughout your upper enteroscopy, you’ll have to remain alert. Your doctor may need you to swallow or move to help get the tube in place. If any growths or other abnormalities are found during enteroscopy, your doctor may remove a sample of tissue for further examination.

较低的肠镜检查

Once you’re sedated, your doctor will insert an endoscope with a balloon on the end into your rectum. Once the endoscope reaches the area that your doctor wants to see or treat, the balloon is inflated. This allows your doctor to get a better view. If any polyps or abnormal growths are found, your doctor may remove a tissue sample for analysis.

This procedure is also called acolonoscopy。

程序后，您可能会遇到一些轻度副作用。这些包括：

  • 喉咙痛
  • abdominal bloating
  • nausea
  • 轻微出血
  • mild cramping

In rare cases, people may have complications after an enteroscopy procedure. These include胰腺炎, internal bleeding, and tearing in the wall of the small intestine. Some people might also have an adverse reaction to the anesthesia. This is why enteroscopy usually isn’t recommended for pregnant women, overweight people, or people with heart or lung disease.

如果您经历过，请务必立即打电话给您的医生：

  • more than a few tablespoons of blood in your stool
  • severe stomach pain
  • 坚定，肚子肿
  • a fever
  • 呕吐

Abnormal results may indicate that the doctor discovered tumors, abnormal tissue, or bleeding in the small intestine. Other possible causes for an abnormal enteroscopy include:

  • 维生素B-12缺乏
  • 胃或肠道病毒
  • 克罗恩病, which is an inflammatory bowel disease
  • lymphoma，这是淋巴结的癌症
  • Whipple disease，这是一种阻止小肠免受吸收营养素的感染

您的医生将安排随访的预约，以解释结果的含义。
