The endoscope is a slender flexible tube with a micro camera on the top and a channel in the tube for various instruments, including snares and biopsy equipment. Endoscopy is a medical method used to help diagnose and treat various gastrointestinal and respiratory diseases. According to the symptoms, it is mainly used to examine the inner wall of the larynx, stomach and intestine, colon or respiratory tract (nose, larynx and lung). Samples from these areas can be collected and analyzed to determine the nature of the disease.
When routine blood test, urine test, X-ray and ultrasound can not determine the cause, endoscopy should be used. Examining the inner walls of the gastrointestinal tract and respiratory tract can help to find the root of the problem more smoothly. For thinner abnormal tissue, the sample can be cut off and taken out for biopsy analysis during endoscopy. In the case of foreign body obstruction, endoscopy is an alternative to "incision surgery".
Endoscopy is generally not recommended if a full-thickness biopsy is required. In addition, endoscopy cannot be used to detect intestinal foreign bodies or midgut diseases.
What can endoscopy be used to examine?
Endoscopy can show whether there are foreign bodies in the stomach. It can also be used to reveal whether there are suspicious or abnormal areas in the stomach, intestine, colon or respiratory tract. If necessary, endoscopy can also help veterinarians with biopsies.
如何對狗進行內窺鏡檢查？內窺鏡檢查在全身麻醉下進行。一旦受影響的狗失去知覺，獸醫就會準備好通氣管，然后可以開始進行內窺鏡檢查。內窺鏡的尖 端將涂有少量潤滑劑，以便更輕松地進入狗的身體。首先將內窺鏡的尖 端放在身體的孔口（例如嘴，結腸或氣管）。然后，操作員使用目鏡進一步將儀器安全地引導通過食道，結腸或呼吸道。在某些情況下，獸醫會將空氣傳遞到試管中以擴大胃腸道，以進行觀察。找到異物或異常區域后，特定的儀器可以通過管中的通道進入體內。通過使用目鏡并操作內窺鏡的尖 端，該儀器可用于檢測特定區域或進行活檢樣本。操作完成后，從腸道中抽出多余的空氣，然后取出內窺鏡。任何活檢樣本須提交給外部實驗室進行分析。
How to do endoscopy in dogs? Endoscopy was performed under general anesthesia. Once the affected dog loses consciousness, the veterinarian will have the ventilation tube ready and can then begin the endoscopy. The tip of the endoscope will be coated with a small amount of lubricant to allow easier access to the dog's body. First, place the tip of the endoscope at the orifice of the body (such as the mouth, colon or trachea). The operator then uses the eyepiece to further safely guide the instrument through the esophagus, colon or respiratory tract. In some cases, veterinarians pass air into test tubes to expand the gastrointestinal tract for observation. After finding the foreign body or abnormal area, the specific instrument can enter the body through the channel in the tube. By using an eyepiece and operating the tip of the endoscope, the instrument can be used to detect specific areas or perform biopsy samples. After the operation, the excess air was extracted from the intestine, and then the endoscope was removed. Any biopsy sample must be submitted to an external laboratory for analysis.
Is endoscopy painless?
Because the operation is performed under anesthesia, the dog does not feel pain. In addition, the test does not involve "incisions", so there is no pain after the operation. However, after the operation, it may cause discomfort due to the temporary placement of the respiratory tube, but the discomfort also varies from dog to dog.
Do endoscopic tests require sedation or anesthesia?
As mentioned above, endoscopic testing requires general anesthesia to keep the dog awake, pain free and muscle relaxed. Under normal circumstances, pets will be given sedatives to help them relax, and then they will be given a brief intravenous anesthesia so that the veterinarian can insert the breathing tube into their trachea, and then continuously inject anesthetic gas into the "unconscious" state during the operation.
