Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Summary
This summary is machine-generated.

Gastrointestinal stromal tumors (GISTs), common mesenchymal tumors, are best diagnosed with endoscopic ultrasonography (EUS) and treated with surgery for localized cases. Endoscopic resection is not recommended for these GI tract tumors.

Area of Science:

  • Gastroenterology and Oncology
  • Gastrointestinal stromal tumors (GISTs) represent a significant area of research within gastrointestinal oncology.

Context:

  • Gastrointestinal stromal tumors (GISTs) are the most common intramural mesenchymal neoplasms of the GI tract, predominantly occurring in the stomach (65%).
  • Endoscopy serves as a primary diagnostic modality for GISTs up to 5cm in diameter.
  • Distinguishing GISTs from other submucosal tumors necessitates advanced imaging techniques.

Purpose:

  • To outline the diagnostic and therapeutic approaches for gastrointestinal stromal tumors (GISTs).
  • To highlight the role of endoscopic ultrasonography (EUS) in GIST diagnosis.
  • To establish the current standard of care for localized GISTs.

Summary:

  • Endoscopic ultrasonography (EUS) is the preferred method for differentiating GISTs from other submucosal tumors.
  • Fine-needle aspiration biopsies (FNABs) are utilized for histological confirmation when required.
  • Surgical intervention is the established gold standard for treating localized GISTs; endoscopic resection is generally not advised.

Impact:

  • This information aids clinicians in selecting appropriate diagnostic tools for suspected GISTs.
  • Clarifies the current treatment guidelines, emphasizing surgery for localized GISTs.
  • Contributes to improved patient management strategies for gastrointestinal stromal tumors.
