Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

1.1K
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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.1K
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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

609
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Endoscopic Procedures III: Video Capsule Endoscopy

1.2K
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: ERCP01:26

Endoscopic Procedures V: ERCP

5.9K
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.

Summary

Colorectal cancer screening faces low public acceptance, leading to late diagnoses. Robotic endoscopic techniques offer a promising advancement to improve patient comfort and colonoscopy acceptance.

Area of Science:

  • Gastroenterology
  • Medical Technology
  • Oncology

Background:

  • Colorectal cancer is a leading cause of cancer mortality in the U.S.
  • Low public acceptance of colonoscopies contributes to late-stage diagnoses in up to 75% of patients.
  • The conventional colonoscope has seen limited innovation, impacting patient experience.

Purpose of the Study:

  • To highlight the need for improved colonoscopy technology.
  • To introduce robotic endoscopic techniques as a promising advancement in colorectal cancer screening.

Main Methods:

  • Review of current colorectal cancer screening practices.
  • Discussion of emerging robotic endoscopic technologies.

Main Results:
