Gastrointestinal endoscopy - gold standard for early diagnosis gastrointestinal cancer

Gastrointestinal endoscopy is a direct examination method that helps to accurately detect lesions in the digestive tract, while other methods can not, especially when a lesion is at early stage.

What is gastrointestinal endoscopy?

Gastrointestinal endoscopy is the common name for gastroscopy and colonoscopy. This is one of the most modern methods available help to diagnose accurately and easily many diseases related to the digestive tract.

The endoscope will be inserted from the nose or mouth to view the upper digestive tract including: esophagus, stomach, duodenum; or inserted from the anus to observe the lower digestive tract including: colon, rectum, anus.

For this procedure, the endoscope will be inserted through the nose or mouth (upper gastrointestinal endoscopy - gastroscopy) or through the anus (lower gastrointestinal endoscopy -colonoscopy). During the endoscopy, the patient is fully awake and may experience some symptoms such as pain, nausea, vomiting, discomfort, etc.

Anesthesia gastrointestinal endoscopy

The patient will be anesthetized prior to the procedure. The anesthetic process take a short time (about 15-20 minutes) so the patient can wake up immediately after finishing. With this method, the patient will feel light, comfortable and there was no pain during examination.

Magnifying endoscopy – detecting cancer in early stage

If in the past, endoscopy was performed using ordinary white light, many gastrointestinal lesions could be missed. Currently, with advanced endoscopy equipment such as laser endoscopes, magnifying endoscopes, virtual staining technique... will accurately detected even the smallest lesions in the gastrointestinal tract.

Endoscopy Center - Hoang Long Clinic is proud of being the units that have successfully applied 4.0 technology to endoscopic techniques, this help to diagnose and detect accurately gastrointestinal cancer in early stage.

  • Endoscope with magnification: The optical and digital magnification of approximately 300 times (equivalent to a microscope) helps to clearly observe the microvascular structure and surface of a lesion, thereby identifying whether it is benign or malignant
  • When a lesion is suspected as malignant, in addition to magnification, the doctor will use LCI (Linked Color Imaging) virtual staining to detect early stage cancer – even very early, when cancer cells only exist in the mucosal layer.

  • BLI, BLI-Bright technology (using narrowband light) highlights the lesion, combine with magnifying feature to help doctors distinguish various lesions and easily identify the lesion which is benign or potentially malignant.
  • Integrated software for early cancer detection and Fuji Intelligent Color Enhancement (FICE) function help identify the change of lesion surface with high-resolution. If a lesion is suspected as cancerous, this lesion will be redder than usual. As a result, it is possible to detect cancer at VERY EARLY stage with high accuracy when compared with biopsy results.

According to statistics, digestive tract cancer such as colon cancer, if detected at an early stage, the survival rate is up to 90%. Many people have been living healthy lives for more than 20 years after being diagnosed with this disease. Therefore, when noticing any abnormal signs, the patient should go to the doctor for timely screening and treatment in order to avoid the serious progression.
