Irritable Bowel Syndrome I: Introduction01:17

Irritable Bowel Syndrome I: Introduction

944
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Endoscopic Procedures III: Video Capsule Endoscopy

793
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,...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

762
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Characteristics of Practical Op Amps01:16

Characteristics of Practical Op Amps

839
A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

Theoretical Foundations of Nursing Practice

17.3K
Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

Inflammatory Bowel Disease II: Crohn's Disease

989
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Summary

Capsule endoscopy is the least invasive method for small bowel investigation, excelling in diagnosing bleeding and tumors. When positive, it guides device-assisted enteroscopy for targeted therapeutics and diagnostics.

Area of Science:

  • Gastroenterology
  • Minimally Invasive Procedures
  • Diagnostic Imaging

Background:

  • Capsule endoscopy (CE) is the least invasive diagnostic tool for small bowel investigation.
  • CE is the first-line test for suspected small bowel bleeding.
  • Meta-analyses indicate CE superiority over traditional imaging for small bowel tumors and equivalence to CT/MR enterography for Crohn's disease.

Purpose of the Study:

  • To review the indications and comparative efficacy of capsule endoscopy and device-assisted enteroscopy (DAE).
  • To compare current guidelines for small bowel investigation using these modalities.
  • To provide a concise overview of CE and DAE in clinical practice.

Main Methods:

  • Review of meta-analyses and clinical guidelines.
  • Comparative analysis of diagnostic yields and therapeutic applications.
  • Discussion of indications for CE and DAE.

Main Results:

  • Capsule endoscopy is highly effective for diagnosing small bowel bleeding and tumors.
  • Device-assisted enteroscopy offers higher diagnostic yield following positive CE and enables therapeutics.
  • DAE has largely replaced intraoperative enteroscopy for therapeutic interventions.

Conclusions:

  • Capsule endoscopy is a primary diagnostic tool for small bowel conditions.
  • Device-assisted enteroscopy is crucial for therapeutic interventions guided by CE findings.
  • Integrated use of CE and DAE optimizes patient management for small bowel diseases.
