Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

48
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 Laproscopy

38
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...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

53
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 II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

41
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:

Esophageal Perforation-II: Clinical Manifestations and Management

31
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

66
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,...

Summary

Diagnosing Meckel's diverticulum (MD) remains challenging. A combination of imaging and endoscopic techniques, alongside a high index of suspicion, is often required for accurate diagnosis and management.

Area of Science:

  • Gastroenterology
  • Diagnostic Imaging
  • Surgical Management

Background:

  • Meckel's diverticulum (MD) is a common congenital anomaly of the ileum.
  • While often asymptomatic, MD can lead to complications like obstruction, diverticulitis, or bleeding.
  • Accurate diagnosis of MD continues to be a challenge in clinical practice.

Purpose of the Study:

  • To review the gastroenterologist's approach to diagnosing Meckel's diverticulum.
  • To outline current diagnostic strategies and management options for MD.
  • To highlight the diagnostic challenges associated with Meckel's diverticulum.

Main Methods:

  • Review of diagnostic modalities including Meckel's scan, small bowel capsule endoscopy (SBCE), and device-assisted enteroscopy (DAE).
  • Discussion of imaging techniques such as CT scans.
  • Analysis of treatment strategies for symptomatic and asymptomatic MD.

Main Results:

  • Meckel's scan sensitivity ranges from 80-92% in children and 62-88% in adults.
  • Small bowel capsule endoscopy (SBCE) has a diagnostic yield of up to 50%.
  • Device-assisted enteroscopy (DAE) shows high sensitivity (84-100%) but is invasive; surgical resection is definitive for symptomatic MD.

Conclusions:

  • Accurate diagnosis of Meckel's diverticulum often necessitates a multimodality approach combining imaging and endoscopy.
  • Surgical resection is the standard treatment for complicated MD.
  • The management of incidental Meckel's diverticulum is debated, but current evidence suggests favoring resection.
