Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

89
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

69
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:

Ultrasonography01:17

Ultrasonography

4.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Ultrasound I: Abdominal Ultrasonography

180
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Area of Science:

  • Gastroenterology and Oncology
  • Medical Imaging Techniques

Background:

  • Gastric cancer is a leading cause of cancer mortality globally.
  • Accurate diagnosis and staging are crucial for effective patient management.

Purpose of the Study:

  • To highlight the role of Endoscopic Ultrasound (EUS) in gastric cancer diagnosis and staging.
  • To demonstrate how EUS findings influence treatment decisions.

Main Methods:

  • Utilizing Endoscopic Ultrasound (EUS) for detailed gastric cancer assessment.
  • Evaluating EUS capabilities in determining tumor characteristics and spread.

Main Results:

  • EUS provides in-depth staging by assessing tumor size, invasion depth, and lymph node/liver metastasis.
  • EUS differentiates various subepithelial gastric masses, including neoplastic lesions.

Conclusions:

  • EUS is instrumental in the accurate staging of gastric cancer.
  • EUS findings directly inform decisions regarding endoscopic or surgical resection and overall patient management strategy.
