Take blood through the endoscope.
Removal of foreign body through endoscopy
Cut polyps through endoscopy.
Esophageal stricture: Esophageal esophagus esophagus, put esophageal stent.
Open the stomach through the skin through the endoscope.
K early stage.

2. Absolute contraindications:

The patient is very old and weak.
Mental patients are not coordinated.
Bleeding diarrhea in many duodenal arteries.
Within 10 days after ingestion.
The large Zenker bag can stray into excess bag causing puncturing.
Patient is pregnant.
Note: 1 patient may be contraindicated but one must consider several factors that can be determined for each situation (benefits received during the procedure, possibility of complications, progression if we do not see).

4. Prepare gastroscopy

Prepare the patient.

Have a thorough examination.
Endoscopic anesthesia examination must be performed
Must have written commitment of the patient or patient’s family before the examination. The most common gastroscopy is anesthesia.
Patients must be thoroughly explained about the benefits and complications of the procedure.

If the patient has a stenosis, wash the stomach before the procedure.
Change clothes for the patient.
Remove false teeth if available.
Explain the procedure to the patient
Preparing medicine.

Take simethicone before the procedure to avoid gastric lavage
Cause 2% xylocain throat or lidocaine 10%
Anti-shock drug adrenaline, intubation set, infusion of sodium chloride 0.9%.
Buscopan injection or seduxen may be given prior to screening.
10% formaldehyde fixed drugs.
HP test reagents (if applicable)
Oxygen system.
Prepare a scanner and an endoscope.

Checking the scanner: light, image, steam pump channel, biopsy channel, left, right, up and down controls.
Check for machine leaks,
Examination of instruments: biopsy pliers, hemostatic needles, strangers, vacuum.
Carry out the colonoscopy


Check to see if the patient is right.
Review medical records (if any).
Posture and patient preparation

To relieve the patient’s discomfort: enough airflow, suction when withdrawing, no longer unnecessary examination.

After washing the machine, disinfect the machine.

6. Complications during endoscopy

Gastric perforation:

50% occur in the pharynx, upper esophagus, sinus, favorable factors: noncooperative patients, esophageal dysfunction or blindness; Management, K esophagus, neck spine. Treatment usually requires surgery.
Two thirds of the esophagus: usually due to inflammatory esophagitis or K, cut K through endoscopy, the procedure for treatment of oesophageal esophagus.
Stomach stomach: usually a few centimeters from the heart. Treatment if puncture need only gastric aspiration and antibiotic therapy, surgery immediately if punctured by the scanner or forcep penetration.

Complications of Heart:

Most of the patients have mild transient feeling including types of arrhythmia: sinus rhythm, extra heart systole, atrial fibrillation. Some factors increase the possibility of arrhythmia: myocardial ischemia, chronic lung disease, older age.

Complications of lung:

Reduced blood oxygenation

Complications pneumonia often occurs when the stomach is more fluid, most food is sedated patients or in the coma.

Deficiency: No cases of progression to sepsis except for patients with reflex.

7. Observation during implementation.

While scans: spO2, pulse, blood pressure.
After the soi: general condition, neck pain, epigastric, pneumothorax.
