"A procedure used in medicine to look inside the body."
A detailed look at the various endoscopic procedures used in gastroenterology, including upper GI endoscopy, colonoscopy, and sigmoidoscopy, including preparation, techniques, and complications.
Anatomy of the Gastrointestinal Tract: Basic understanding of the structure and function of the gastrointestinal (GI) tract is essential to understand the indications and techniques of endoscopy.
Endoscopy Equipment and Accessories: Understanding the equipment used for endoscopy and its proper care and maintenance is critical for safe and effective procedures.
Patient Preparation and Sedation: Patient preparation and sedation are necessary for a successful endoscopic procedure, and these techniques should be tailored to the patient's age, physical status, and the procedure being performed.
Basic Endoscopic Techniques: The basic techniques involved in endoscopy include intubation, navigation, insufflation, suctioning, biopsy, and polypectomy.
Endoscopic Imaging: Endoscopic imaging techniques, including high-definition imaging, chromoendoscopy, and virtual chromoendoscopy, provide important information for diagnosis and treatment.
Endoscopic Ultrasonography: Endoscopic ultrasonography (EUS) is a powerful tool for the diagnosis and staging of GI diseases and is widely used in gastroenterology.
Endoscopic Retrograde Cholangiopancreatography: Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced endoscopic technique used for the diagnosis and treatment of biliary and pancreatic diseases.
Endoscopic Mucosal Resection: Endoscopic mucosal resection (EMR) is a minimally invasive technique used for the removal of superficial lesions, including polyps and early-stage cancers, from the GI tract.
Endoscopic Submucosal Dissection: Endoscopic submucosal dissection (ESD) is a more advanced technique used for the removal of larger or deeper lesions from the GI tract.
Therapeutic Endoscopy: Therapeutic endoscopy involves endoscopic techniques used for the treatment of GI disorders, including stent placement, stricture dilation, and ablation therapy.
Complications of Endoscopy: Complications of endoscopy include bleeding, perforation, and infection, and understanding these potential risks is essential for ensuring safe and effective procedures.
Quality Assurance in Endoscopy: Quality assurance involves evaluation of the quality of endoscopic procedures and the effectiveness of endoscopic techniques, equipment, and personnel.
Esophagoscopy: This procedure is used to examine the esophagus, the tube that carries food from your mouth to your stomach. It is usually done to identify the causes of swallowing problems, such as inflammation, ulcers, tumors, and other abnormalities.
Upper gastrointestinal endoscopy: This procedure is also known as an EGD (esophagogastroduodenoscopy). It is done to examine the upper digestive tract, which includes the esophagus, stomach, and duodenum. This procedure is often recommended to investigate the causes of abdominal pain, reflux, ulcers, and other gastrointestinal symptoms.
Colonoscopy: This procedure is done to examine the colon or large intestine. It is used to identify polyps, tumors, inflammation, and other abnormalities in the colon. Colonoscopy is often recommended to screen for colorectal cancer, especially in people over 50 years of age.
Sigmoidoscopy: This procedure is used to examine the sigmoid colon, the lower part of the large intestine that connects to the rectum. It is often recommended to investigate the causes of blood in the stool, pain, and other symptoms of the lower digestive tract.
Capsule endoscopy: This is a non-invasive procedure that uses a small capsule equipped with a camera to examine the small intestine. The capsule is swallowed and takes pictures as it passes through the digestive tract, which are transmitted to a recording device. This procedure is often recommended to investigate the causes of unexplained abdominal pain and bleeding.
Endoscopic ultrasound: This procedure combines endoscopy with ultrasound imaging to examine the digestive tract and surrounding organs, such as the liver, pancreas, and lymph nodes. It is often recommended to identify tumors, cysts, and other abnormalities in the digestive system.
Endoscopic retrograde cholangiopancreatography (ERCP): This procedure is used to examine the bile ducts and pancreatic ducts. It involves inserting an endoscope through the mouth and into the duodenum, and then injecting contrast dye to visualize the ducts on X-rays. ERCP is often recommended to investigate the causes of jaundice, pancreatitis, and other digestive disorders.
Enteroscopy: This procedure is used to examine the small intestine. It involves inserting an endoscope either through the mouth or through the anus and advancing it through the digestive system to the small intestine. Enteroscopy is often recommended to investigate the causes of malabsorption, unexplained pain, and bleeding in the small intestine.
Endoscopic mucosal resection (EMR): This procedure is used to remove abnormal tissues, such as polyps or tumors, from the digestive tract without needing surgery. It involves inserting an endoscope through the mouth or anus and removing the abnormal tissue using special tools.
Balloon-assisted endoscopy: This is a type of endoscopy that uses a balloon attached to the endoscope to help navigate through the digestive system. It is often recommended to investigate the causes of small intestinal bleeding and to obtain tissue samples for biopsy.
"The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body."
"Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ."
"There are many types of endoscopies."
"Depending on the site in the body and type of procedure, an endoscopy may be performed by either a doctor or a surgeon."
"A patient may be fully conscious or anaesthetized during the procedure."
"Most often, the term endoscopy is used to refer to an examination of the upper part of the gastrointestinal tract, known as an esophagogastroduodenoscopy."
"For nonmedical use, similar instruments are called borescopes."
