Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

504
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 IV: Sigmoidoscopy and Laproscopy

354
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 II: Colonoscopy

406
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
  • Surgical Robotics
  • Endoscopic Procedures

Background:

  • Endoscopic submucosal dissection (ESD) faces challenges with tissue retraction.
  • The EndoMaster EASE System utilizes robotic arms to improve ESD safety and efficacy.

Purpose of the Study:

  • To evaluate the performance of colorectal ESD using the latest EndoMaster EASE System in a preclinical animal model.

Main Methods:

  • The study involved 5 colorectal ESD procedures in a porcine model using the EndoMaster EASE System.
  • Outcome measures included operative time, resection completeness, adverse events, and arm manipulation limitations.

Main Results:

  • Mean operative time was 73.8 minutes for resecting specimens averaging 1340 mm².
  • No perforations occurred, but one procedure experienced significant bleeding.

Conclusions:

  • The latest EndoMaster EASE System demonstrated feasibility for colorectal ESD in preclinical settings.
  • The system showed potential for managing adverse events, providing valuable data for future clinical trials.
