Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

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, unexplained...
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

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 I: Esophagogastroduodenoscopy

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 IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...
Urologic Endoscopic Procedure: Cystoscopic Examination01:28

Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

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:

Summary
This summary is machine-generated.

Endoscopic capsule delivery to the duodenum is rarely needed but can safely overcome swallowing difficulties or gastric retention. Techniques like retrieval nets and translucent caps ensure complete small bowel imaging when capsule endoscopy (CE) is challenging.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Medical Devices

Background:

  • Capsule endoscopy (CE) can be hindered by swallowing difficulties or gastric retention.
  • Endoscopic delivery of the capsule to the duodenum offers a solution in such cases.
  • This study details the indications and outcomes of endoscopic capsule placement.

Purpose of the Study:

  • To describe the indications for endoscopic capsule delivery to the duodenum.
  • To evaluate the outcomes and safety of various endoscopic techniques for capsule placement.
  • To identify optimal methods for overcoming CE limitations.

Main Methods:

  • Retrospective, descriptive case series of patients requiring endoscopic capsule placement.
  • Data collected included indications, endoscopic techniques used, complications, and imaging completeness.
  • Patients were categorized based on swallowing ability and capsule retention.

Main Results:

  • Endoscopic delivery was necessary in 13 patients (2.1% of CE cases).
  • Indications included inability to swallow (7), gastric retention (3), and abnormal anatomy (3).
  • Successful complete small bowel imaging was achieved in 77% of patients, with no major complications.

Conclusions:

  • Endoscopic duodenal capsule placement is infrequently required but safe and effective.
  • Techniques like retrieval nets with translucent caps or nets alone can overcome CE limitations.
  • This approach ensures diagnostic yield when standard capsule ingestion fails.
