This video demonstrate Dr R K Mishra delivering lecture on Overview of Endoscopy at World Laparoscopy Hospital. Endoscopic surgery uses scopes going through small incisions or natural body openings in order to diagnose and treat disease. Another popular term is minimally invasive surgery (MIS), which emphasizes that diagnosis and treatments can be done with reduced body cavity invasion.
Endoscopy is a minimally invasive diagnostic and therapeutic procedure that involves using a flexible tube with a camera and a light on the end to visualize and access various organs and structures inside the body. Endoscopy is commonly used to evaluate the gastrointestinal (GI) tract, including the upper GI tract (esophagus, stomach, and duodenum) and the lower GI tract (colon and rectum).
Upper GI endoscopy, also known as esophagogastroduodenoscopy (EGD), is a procedure that allows visualization and assessment of the esophagus, stomach, and duodenum. The procedure is typically performed with the patient under conscious sedation. The steps to perform an upper GI endoscopy are as follows:
-
The patient is asked to lie on their left side with their head turned to the right.
-
A small, flexible tube with a camera and a light on the end, called an endoscope, is inserted through the mouth and into the esophagus.
-
The endoscope is guided through the esophagus, into the stomach, and then into the duodenum.
-
The endoscope allows the doctor to visualize the lining of the esophagus, stomach, and duodenum and look for any abnormalities such as inflammation, ulcers, or tumors.
-
If a suspicious area is identified, the doctor may take a biopsy (a small tissue sample) for further evaluation.
Lower GI endoscopy, also known as colonoscopy, is a procedure that allows visualization and assessment of the colon and rectum. The procedure is typically performed with the patient under conscious sedation. The steps to perform a lower GI endoscopy are as follows:
-
The patient is asked to lie on their left side with their knees bent.
-
A small, flexible tube with a camera and a light on the end, called a colonoscope, is inserted through the anus and into the rectum.
-
The colonoscope is guided through the rectum, into the colon, and then into the cecum (the beginning of the large intestine).
-
The colonoscope allows the doctor to visualize the lining of the colon and rectum and look for any abnormalities such as inflammation, ulcers, or tumors.
-
If a suspicious area is identified, the doctor may take a biopsy (a small tissue sample) for further evaluation.
Both upper and lower GI endoscopy are generally safe and well-tolerated. However, as with any medical procedure, there are risks involved, such as bleeding, infection, or perforation of the organ being evaluated. It is important for patients to discuss the risks and benefits of the procedure with their healthcare provider before undergoing endoscopy.
