Cytology of upper gastrointestinal tract

  • How do you perform a cytology test?

    Some of the ways a provider can collect cytology test samples include:

    1. Brushing or scraping tissue from the surface of a part of your body
    2. Collecting fluid or discharge samples from your body, such as a pee sample
    3. Using fine-needle aspiration to draw a fluid sample from an area in your body

  • What does the upper gastrointestinal tract consist of?

    The upper digestive tract includes the esophagus (the tube that connects the mouth to the stomach), the stomach, and the duodenum (the first part of the small intestine)..

  • What is cytology of the gastrointestinal tract?

    Cytology of the GIT is performed to detect neoplastic and nonneoplastic lesions and often includes concurrent procurement of needle core biopsies.
    Sites amenable to cytological sampling include the esophagus, stomach, duodenum, pancreatobiliary, and liver from the upper GIT and the rectum and anus from the lower GIT..

  • What is included in the upper GI tract?

    The upper GI tract includes your food pipe (esophagus), stomach, and the first part of your small intestine (the duodenum)..

  • What is included in the upper GI?

    Your upper GI includes your esophagus, stomach and duodenum.
    Fluoroscopy produces moving-picture X-rays that show your organs in action.
    The test can help your doctor find functional and structural abnormalities..

  • What is the definition of the upper gastrointestinal tract?

    It's made up of a series of hollow organs that connect together to form a tube, beginning at your mouth and ending at your anus. “Upper GI” refers to your upper gastrointestinal tract.
    That means your esophagus (swallowing pipe), your stomach and the first part of your small intestine (duodenum)..

  • Abstract.
    The upper gastrointestinal (GI) tract is composed of the oral cavity and salivary glands, the esophagus, stomach, and small intestine (duodenum, jejunum, and ileum).
  • The upper digestive tract includes the esophagus (the tube that connects the mouth to the stomach), the stomach, and the duodenum (the first part of the small intestine).
  • The upper gastrointestinal (GI) tract is composed of the oral cavity and salivary glands, the esophagus, stomach, and small intestine (duodenum, jejunum, and ileum).
Exfoliative cytology can be performed easily along with mucosal biopsy during endoscopic examination of the GI tract. Cytologic smears may be made by the brush or touch technique and are graded by objective criteria. Endoscopic cytologic specimens have a high diagnostic accuracy compared with histologic specimens.
Cytology of gastro-intestinal (GI) tract lesions can be used successfully to diagnose neoplastic and non-neoplastic conditions, especially when combined with biopsies. Cytologic evaluation is widely accepted as a cost-effective method that allows rapid interpretation and triaging of material.
The selective use of brushing cytology should increase the probability of detecting malignancies and fungal infections without any increased risk or discomfort 

What is GI cytology?

The popularity of gastrointestinal (GI) cytology for the diagnosis of infection and malignancy has waxed and waned during the past few decades.

,

What organs make up the upper gastrointestinal tract?

Besides the esophagus, organs of the upper gastrointestinal (GI) tract include:

  1. the mouth
  2. pharynx
  3. stomach

These hollow organs are all connected to form a tube through which food passes during digestion.
The only role in digestion played by the pharynx and esophagus is to move food through the GI tract.
,

Where is the gastrointestinal tract located?

The gastrointestinal (GI), or digestive, tract extends from mouth to anus (see the image below).
The division of the GI tract into upper and lower is a matter of some confusion and debate.

,

Which GI tract should be divided based on embryologic grounds?

On embryologic grounds, the GI tract should be divided into upper (mouth to major papilla in the duodenum ), middle (duodenal papilla to mid-transverse colon), and lower (mid-transverse colon to anus), according to the derivation of these 3 areas from the foregut, midgut, and hindgut, respectively.
