Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

377
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,...

Endoscopic Procedures I: Esophagogastroduodenoscopy

425
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

1.1K
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 Procedures IV: Sigmoidoscopy and Laproscopy

221
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...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies01:28

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

234
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

250
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:

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Robotics

Background:

  • Wireless capsule endoscopy (WCE) initially focused on small intestine visualization.
  • Stomach observation via WCE presents unique challenges due to anatomy and required motility.
  • Esophagogastroduodenoscopy is the traditional method, but WCE offers a less invasive alternative.

Purpose of the Study:

  • To review magnetic locomotion systems for stomach observation using WCE.
  • To highlight advancements in overcoming technical obstacles for gastric WCE.
  • To assess the safety and efficacy of magnetic WCE for the stomach.

Main Methods:

  • Review of magnetic manipulation techniques for capsule control within the stomach.
  • Discussion of hand-held paddles, robotic arms, and electromagnetic coil systems.
  • Analysis of studies involving healthy volunteers and patients with upper GI symptoms.

Main Results:

  • Magnetic manipulation is the sole clinically utilized system for gastric capsule control.
  • Studies demonstrate WCE with magnetic control is safe and effective for stomach examination.
  • Various magnetic locomotion systems have been developed and tested for gastric WCE.

Conclusions:

  • Magnetic locomotion systems represent a significant advancement in wireless capsule endoscopy for stomach visualization.
  • Controlled magnetic WCE is a viable and effective alternative to traditional upper gastrointestinal endoscopy.
  • Further development in magnetic locomotion promises enhanced diagnostic capabilities for gastric conditions.
