Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

384
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 V: ERCP

1.2K
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

227
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

173
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

439
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 II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

259
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
  • Minimally Invasive Endoscopic Surgery
  • Oncology

Background:

  • Endoscopic submucosal dissection (ESD) is a standard therapy for early gastrointestinal tumors.
  • Existing electrosurgical knives present technical challenges and high complication rates (bleeding, perforation).
  • A need exists for a simpler, safer, and more effective device for ESD.

Purpose of the Study:

  • To evaluate the Clutch Cutter (CC), a novel forceps-type resection device, for endoscopic submucosal dissection (ESD).
  • To assess the safety, efficacy, and ease of use of ESD with the CC (ESD-CC).
  • To explore the utility of the CC in other endoscopic therapeutic applications.

Main Methods:

  • Review of clinical studies and reported data on the use of the Clutch Cutter (CC) for ESD.
  • Analysis of the CC's design, focusing on its grasping and electrosurgical capabilities.
  • Comparison of ESD-CC outcomes with conventional ESD techniques, including complication rates and resection success.

Main Results:

  • ESD-CC demonstrated favorable safety profiles with low perforation (0%-3.6%) and delayed bleeding (0%-4.2%) rates.
  • High en-bloc resection rates (88.9%-100%) were achieved, indicating technical efficiency.
  • The CC's simple grasp, pull, and coagulate/incise technique was easier to learn, with significantly higher self-completion rates by non-experts compared to conventional knives (61.7% vs. 24.5%).
  • The CC has shown promising results in other endoscopic therapies, including large polyp removal, Zenker's diverticulum treatment, and pancreatic necrosectomy.

Conclusions:

  • The Clutch Cutter (CC) is a safe, effective, and technically efficient single-device solution for ESD of early gastrointestinal tumors.
  • The CC simplifies the ESD procedure, making it easier to learn and perform, especially for non-experts.
  • The CC's versatility extends to various other complex endoscopic therapies, with initial reports indicating favorable outcomes.
