Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

1.0K
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 II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

659
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

3.0K
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 IV: Sigmoidoscopy and Laproscopy

616
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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

87.0K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Urologic Endoscopic Procedure: Cystoscopic Examination

2.6K
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...

Area of Science:

  • Gastroenterology
  • Pediatric Research
  • Inflammatory Bowel Disease

Background:

  • Advancing inflammatory bowel disease (IBD) understanding necessitates human intestinal tissue for mechanistic studies.
  • Pediatric IBD research is vital for this underserved population.
  • Limited data exist on the safety of research biopsies in children.

Purpose of the Study:

  • To evaluate the safety of obtaining research biopsies in pediatric subjects.
  • To inform institutional review boards (IRBs) on risk-benefit analysis for pediatric IBD research.

Main Methods:

  • Review of existing literature on pediatric biopsy safety.
  • Analysis of institutional review board (IRB) considerations for pediatric research.

Main Results:

  • Clinical biopsies in children are generally considered safe.
  • Specific data on research biopsy safety in pediatric populations are scarce.
  • IRBs must carefully weigh research benefits against perceived risks for children.

Conclusions:

  • Further research is needed to establish clear safety guidelines for pediatric research biopsies in IBD studies.
  • Ensuring child safety is paramount while facilitating critical pediatric IBD research.
