內(nèi)窺鏡是一根細(xì)長(zhǎng)的撓性管，頂部帶有微型攝像頭，管中有一個(gè)通道，可讓各種儀器通過(guò)，包括圈套器和活檢設(shè)備。內(nèi)窺鏡是用于幫助診斷和各種胃腸道和呼吸系統(tǒng)疾病的醫(yī)學(xué)方法。根據(jù)癥狀，主要用于檢查喉，胃和腸的內(nèi)壁，結(jié)腸或呼吸道（鼻，喉和肺），可以收集這些區(qū)域的樣本，然后進(jìn)行分析以確定疾病的性質(zhì)。

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.

當(dāng)常規(guī)血液檢查，尿液檢查，x光和超聲檢查無(wú)法確定原因時(shí)，應(yīng)使用內(nèi)窺鏡檢查。檢查胃腸道和呼吸道的內(nèi)壁有助于更順利地找到問(wèn)題的根源。對(duì)于較薄的異常組織，可以在內(nèi)窺鏡檢查過(guò)程中將樣品切下并取出進(jìn)行活檢分析。在異物阻塞的情況下，內(nèi)窺鏡檢查是可以替代“切口手術(shù)”的方法。

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".

如果需要進(jìn)行全層活檢，通常不建議使用內(nèi)窺鏡。此外，內(nèi)窺鏡無(wú)法用于檢測(cè)腸道異物或中腸疾病。

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.

內(nèi)窺鏡可以用來(lái)檢查什么？

What can endoscopy be used to examine?

內(nèi)窺鏡檢查可以顯示胃中是否有異物。它也可用于揭示胃，腸，結(jié)腸或呼吸道中是否有可疑或異常區(qū)域。如有必要，內(nèi)窺鏡還可以幫助獸醫(yī)進(jìn)行活檢。

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(duì)進(jìn)行內(nèi)窺鏡檢查？?jī)?nèi)窺鏡檢查在全身麻醉下進(jìn)行。一旦受影響的失去知覺(jué)，獸醫(yī)就會(huì)準(zhǔn)備好通氣管，然后可以開(kāi)始進(jìn)行內(nèi)窺鏡檢查。內(nèi)窺鏡的尖 端將涂有少量潤(rùn)滑劑，以便更輕松地進(jìn)入的身體。將內(nèi)窺鏡的尖 端放在身體的孔口（例如嘴，結(jié)腸或氣管）。然后，操作員使用目鏡進(jìn)一步將儀器地引導(dǎo)通過(guò)食道，結(jié)腸或呼吸道。在某些情況下，獸醫(yī)會(huì)將空氣傳遞到試管中以擴(kuò)大胃腸道，以進(jìn)行觀察。找到異物或異常區(qū)域后，特定的儀器可以通過(guò)管中的通道進(jìn)入體內(nèi)。通過(guò)使用目鏡并操作內(nèi)窺鏡的尖 端，該儀器可用于檢測(cè)特定區(qū)域或進(jìn)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(nèi)窺鏡。任何活檢樣本須提交給外部實(shí)驗(yàn)室進(jìn)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.

內(nèi)窺鏡檢查無(wú)痛嗎？

Is endoscopy painless?

因?yàn)槭中g(shù)是在麻醉下進(jìn)行的，所以不會(huì)感到疼痛。另外，該測(cè)試不會(huì)涉及“切口”，因此手術(shù)后不會(huì)有疼痛感。但是，在手術(shù)后，可能由于呼吸管的臨時(shí)放置而引起不適，但是這種不適也因而異。

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.

內(nèi)窺鏡測(cè)試是否需要或麻醉？

Do endoscopic tests require sedation or anesthesia?

如上所述，內(nèi)窺鏡測(cè)試需要全身麻醉，以使保持神志清醒，無(wú)疼痛和肌肉松弛的狀態(tài)。在正常情況下，寵物將獲得藥以幫助其放松，然后對(duì)其進(jìn)行簡(jiǎn)短的靜脈麻醉，以使獸醫(yī)將呼吸管插入其氣管，然后在手術(shù)過(guò)程中連續(xù)注入麻醉氣體“無(wú)意識(shí)”狀態(tài)。

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.
