An upper GI endoscopy is the most exact test method to detect colon cancer in its early stages.
The endoscope is inserted through the mouth to observe the interior of the esophagus, stomach and the duodenum and if an abnormality is found, a blue pigment if sprayed for a more detailed observation, a biopsy is done to observe through a microscope, or an image of the interior is printed out for comparison. The endoscope can be used to remove any polyps and to stop bleeding according to the circumstances.
Although an upper GI series can also be performed, an endoscopy is more accurate, allows an immediate biopsy when necessary and can quickly perform an accurate test for the bacteria called Helicobacter pylori, which is known to be the cause of gastroduodenal ulcers.

A tranquilizer is injected to induce the patient into a light sleep before using the endoscope so the patient does not feel any pain and does not move, which allows thorough observation of the intestines or stomach. The test can be accurately performed in comfort since the patient has no recollection of any discomfort or pain involved in the procedure when the test is finished,
Apart from patients suffering from a chronic lung disease, in which case the tranquilizer can be harmful, anyone can receive the test and the patient should remain stable for 2 hours after the surgery and refrain from exercising.

Upper GI Endoscopy under Procedural Sedation
& Upper Abdominal Ultrasound

Conditions detectable through an upper gastrointestinal endoscopy
The upper GI endoscopy under procedural sedation is a comfortable and safe procedure due to the fact that the patient is sleeping during the whole process. It can be used to diagnose upper GI conditions including esophageal cancer, stomach cancer, gastric ulcers, and duodenal ulcers. Korea has many cases of stomach cancer and early stage stomach cancer can be cured 90~95% of the time through surgery if detected early using an endoscopy. A biopsy and a Helicobacter pylori test can also be performed during the endoscopy if necessary.

Conditions Detectable through an Upper Abdominal Ultrasound
An upper abdomen ultrasound is a simple method to diagnose liver cancer, pancreatic cancer and cholelithiasis, which are common in Korea. It is safe to also receive an ultrasound with the endoscopy since many gastrointestinal diseases show similar symptoms. In addition, receiving a tumor marker test (CA19-1) through a blood test as a supplementary examination can increase the chance of diagnosis for pancreatic cancer since it can be difficult to diagnose through an ultrasound or a CT scan.


If necessary, Zion Women셲 Hospital performs endoscopies, ultrasounds and tumor marker tests (blood tests) in a suitable combination in order to increase the diagnosis rate for gastrointestinal cancers.

A colonoscopy is a test to see the overall form of the colon using an endoscope in order to determine the state of the colon.

The procedure is essential to the diagnosis of colon and anal conditions since it can not only be used to diagnose but also treat cancer.
Since most cases of colon cancer develop from adenomas, the incidence rate for colon cancer can be drastically reduced by detecting and removing the adenomas before they develop into cancer.
Moreover, polyps and early stage colon cancer can be treated surgically through a colonoscopy or through endoscopic measures.

Colonoscopy under Procedural Sedation

01. Definition of a Colonoscopy
A colonoscopy is best performed by a gastroenterologist.
Receiving a colonoscopy under sedation will eliminate any discomfort and allow for a more comfortable test.

02. Colorectal Cancer & Colonic Polyps
Approximately 10% of cancer patients in Korea suffer from colon cancer and the number is increasing.
Colonic polyps are abnormal lesions on the colonic mucosa that are protruding and 54% of such polyps grow into colon cancer. Colonic polyps are the most significant cause of colon cancer. Approximately 20% of those over 40 have colonic polyps while up to 30~40% of those over 60 have them. The polyps must be removed through a colonoscopy and since they are mostly accompanied with no symptoms and are found by chance, those over 35 should receive a colonoscopy. (If there are symptoms, those in their 20~30s may also need to receive the procedure.)

03. Definition of a Colonic Polypectomy
A colonic polypectomy is the removal of colonic polyps using colonoscopy. Removing the colonic polyps prevents colon cancer.

04. Precautions for a Colonic Polypectomy
Patients who have had a pacemaker installed or who are taking Coumadin or aspirin have a higher risk in surgery due to the possibility of the pacemaker breaking and the higher chance of hemorrhaging.

05. Preparations for a Colonoscopy
Patients who have had a pacemaker installed or who are taking Coumadin or aspirin have a higher risk in surgery due to the possibility of the pacemaker breaking and the higher chance of hemorrhaging. Therefore consultations with the doctor regarding the issue are necessary.

01. A healthy person receive a bottle of colonic irrigation fluid (from the doctor) and have 쩍 of the bottle at 7pm and the remaining 쩍 at 10pm on the night before the test (dilute to about 1 cup). Elderly patients will receive a different type of irrigation fluid after consulting the doctor.
02. Take 2 pills on the morning of the day before the test.
03. Eat bread and milk for all three meals for the day before the test, have dinner before 5pm, and drink only water after that.
04. Drink a lot of water to prevent dehydration. Water must be drunken regularly before and on the day of the test.
05. Avoid fruit with seeds 2~3 days before the test.

Administration Method for the Colonic Irrigation Fluid
3 days before the test Food such as sea mustard, kelp, black rice, miscellaneous cereals, grape juice and fruit with seeds including oriental melons, watermelons, and grapes must be avoided.
The night before the test Eat thin rice gruel or rice porridge (salt O, soy sauce O, kimchi X, side dishes X)
5am on the
Day of the test
Hypertension medication O, diabetes medication X, aspirin prohibited from a week before
1. Administration of the first medicine on the night before the test
Mix medicine A and B in an empty water bottle, pour in 500ml of water, mix the water to melt the power and take 250ml every 15 minutes.
Take another round in the same way. Take a total of 1L in an hour and drink an additional 500ml of water.
2. Administration of the second medicine on the morning of the test
Mix medicine A and B in an empty water bottle, pour in 500ml of water, mix the water to melt the power and take 250ml every 15 minutes. Take another round in the same way. Take a total of 1L in an hour and drink an additional 500ml of water.
