Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
Barrett Esophagus-I: Introduction01:21

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

Gastritis III: Clinical Manifestations and Management

The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

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:
Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...

Area of Science:

  • Oncology
  • Surgical Oncology
  • Gastroenterology

Background:

  • Global cancer therapy relies on established guidelines.
  • The Japan Gastric Cancer Association guideline recommends extensive surgery for advanced gastric cancer.
  • D2 dissection is a key component of standard surgical practice in Eastern countries.

Purpose of the Study:

  • To evaluate the efficacy of D2 dissection in gastric cancer treatment.
  • To assess the role of adjuvant chemotherapy in conjunction with D2 dissection.
  • To emphasize the importance of local control in improving gastric cancer cure rates.

Main Methods:

  • Review of surgical guidelines and clinical data.
  • Analysis of outcomes comparing D2 dissection with less extended surgery.
  • Evaluation of adjuvant chemotherapy's impact on survival post-D2 dissection.

Main Results:

  • D2 dissection yields superior results compared to less extensive surgery in the East.
  • Adjuvant chemotherapy significantly improves survival only when combined with D2 dissection.
  • Effective local control, including lymph node management, is crucial for high cure rates.

Conclusions:

  • D2 dissection is essential for effective gastric cancer treatment.
  • Adjuvant chemotherapy enhances survival outcomes when D2 dissection is performed.
  • Achieving good local control is paramount for improving gastric cancer cure rates.
