Endoscopic Procedures III: Video Capsule Endoscopy

784
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,...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

480
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

The Colonization of Land

37.4K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Immune Surveillance by NK Cells and Phagocytes

7.9K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

499
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules

312
Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...

Area of Science:

  • Gastroenterology
  • Medical Devices
  • Public Health

Background:

  • The National Health Service implemented colon capsule endoscopy (CCE) during the COVID-19 pandemic as an alternative to colonoscopy for patients needing 3-year post-polypectomy surveillance.
  • This aimed to address capacity issues and provide patient choice in colorectal cancer screening.

Purpose of the Study:

  • To evaluate the safety, diagnostic accuracy, and clinical utility of CCE in patients undergoing surveillance after polypectomy.
  • To determine the effectiveness of CCE in managing patient pathways and sparing colonoscopy capacity.

Main Methods:

  • A comparative study involving patients undergoing either CCE or colonoscopy for 3-year post-polypectomy surveillance.
  • Development of a risk-based guidance system for CCE patients to direct subsequent endoscopic intervention, deferral, or discharge.
  • Assessment of safety, diagnostic accuracy (sensitivity for polyp detection), and colonoscopy capacity utilization.

Main Results:

  • 99% of patients tolerated CCE safely. Higher detection rates for larger polyps (≥ 10 mm and 6-9 mm) were observed in the CCE cohort compared to the colonoscopy cohort.
  • Per-patient sensitivities for detecting ≥ 10 mm and 6-9 mm polyps were 92% and 90%, respectively.
  • Two-thirds of CCE patients followed a modified management pathway, with 25% discharged and 27% having procedures deferred; completion and preparation rates were 78% and 73%.

Conclusions:

  • Colon capsule endoscopy is a safe diagnostic method for identifying colorectal polyps in a surveillance setting.
  • CCE acts as a "filter function," augmenting existing colorectal diagnostic services by increasing capacity and providing patient choice.
