Advanced Endoscopy procedures


What Are Advanced Endoscopy Procedures?


Advanced endoscopy” is a term used to describe therapeutic procedures in which endoscopy is a primary tool, including endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreatography (ERCP), stent placements, and endoscopic resections, among others.
“







How do advanced endoscopy procedures differ from traditional endoscopy techniques?


Scope technology: Advanced endoscopy procedures often utilize specialized endoscopes with additional features and capabilities compared to traditional endoscopes. These advanced endoscopes may have features such as high-definition imaging, narrow-band imaging, or built-in ultrasound probes.

Advanced imaging and guidance: Advanced endoscopy procedures often incorporate advanced imaging technologies such as narrow-band imaging, which enhances the visualization of subtle mucosal changes. Additionally, techniques like EUS combine endoscopy with ultrasound imaging to provide detailed images and guide interventions.

Expertise and training: Advanced endoscopy procedures require specialized training and expertise beyond standard endoscopy techniques. Gastroenterologists or interventional endoscopists undergo additional training to perform these procedures safely and effectively.

FOR DEATILED INFO -








Are there any risks or complications associated with advanced endoscopy procedures?




Bleeding: During certain advanced endoscopy procedures, there is a small risk of bleeding, particularly if tissue is manipulated, biopsies are taken, or polyps are removed. However, this risk is generally low and can often be managed during the procedure.


Perforation: There is a small risk of perforation or creating a hole in the gastrointestinal tract during advanced endoscopy procedures, especially those involving tissue resection or complex interventions. However, the incidence of perforation is relatively low and is typically managed promptly during the procedure.


Infection: While advanced endoscopy procedures are performed using sterile techniques to minimize the risk of infection, there is still a small chance of developing an infection. Infections can occur at the site of the procedure or within the gastrointestinal tract. However, the risk of infection is generally low.






What are the success rates of advanced endoscopy procedures in treating different conditions?


Endoscopic Retrograde Cholangiopancreatography (ERCP): ERCP has a high technical success rate, typically exceeding 90%. The clinical success rate varies depending on the specific indication. For example, in cases of gallstone removal or stent placement to relieve bile duct obstruction, success rates can range from 80% to 95%.


Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD): Success rates for EMR and ESD in the removal of precancerous or early-stage gastrointestinal lesions can be high, with complete removal achieved in 80% to 95% of cases. However, the success rates can vary depending on the size, location, and characteristics of the lesion.


Endoscopic Ultrasound (EUS) for staging cancers: EUS has proven to be highly accurate in staging gastrointestinal cancers, with reported accuracy rates of approximately 80% to 90%. This helps guide appropriate treatment decisions and interventions.

What is Gastric Polyps?

Image
Gastric Polyps  Gastric polyps are masses or a small aggregation of cells seen in the stomach. They represent areas of higher-than-normal proliferative growth and may potentially turn neoplastic.    They can be further sub-divided into  1) Gastric hyperplastic polyps  2) Fundic gastric polyp  3) Adenomatous polyp s Most polyps are diagnosed incidentally on upper GI endoscopy. Gastric hyperplastic polyps are associated with chronic H.pylori infection and atrophic gastritis.  Risks associated with gastric polyps    1. Age     2. Chronic H.pylori infection    3. Chronic gastritis due to any cause    4. Genetically inherited polyposis syndromes like Familial adenomatous polyposis (FAP) Clinical features  Majority of the polyps are asymptomatic and are incidentally found. However, a     fraction of cases may present with    1. Heartburn and chest discomfort    2. Indigestio...

Endoscopic submucosal dissection

Image
Endoscopic Submucosal Dissection  Endoscopic submucosal dissection (ESD) is a procedure to remove tumors from the gastrointestinal (GI) tract. It is done under general anesthesia and is done mostly on outpatient basis.  It is done using a high-definition upper GI endoscope either through the mouth or anus (depending on location of the tumor). An electrosurgical knife used to cut the tumor from the adjacent tissue with the use of high-frequency electrical current.  The knife also aids in cauterizing any bleed during the procedure. The tissue which is excised is then sent for histopathological examination. It is indicated in: -  1. Early-stage cancer of the GI tract (especially esophagus)  2. Polyps  3. Non-invasive tumors of the stomach or large intestine  4. Pre-malignant diseases like Barrett’s Special note: -  a) Because it is special minimally invasive procedure, the organ of involvement is preserved. This helps maintain quality of life fo...
