Esophageal Strictures-II: Clinical Features and Management01:26

Esophageal Strictures-II: Clinical Features and Management

283
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

843
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

421
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Esophageal Perforation-II: Clinical Manifestations and Management01:28

Esophageal Perforation-II: Clinical Manifestations and Management

282
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.

Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

281
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Achalasia is a neurodegenerative esophageal disorder causing swallowing difficulties and malnutrition.
  • Current treatments for achalasia present challenges, impacting patient quality of life.

Purpose of the Study:

  • To evaluate the long-term safety and efficacy of Peroral Endoscopic Myotomy (POEM) for achalasia treatment.

Main Methods:

  • POEM involves creating a submucosal tunnel to divide the esophageal muscular layer.
  • Analysis of ten-year outcomes for patients undergoing POEM for achalasia.

Main Results:

  • Ten-year data demonstrate POEM as a safe and effective treatment for achalasia.
  • Gastroesophageal reflux disease (GERD) is a notable consideration following POEM procedures.

Conclusions:

  • POEM provides a viable long-term therapeutic option for achalasia.
  • Managing postoperative GERD is crucial for optimizing patient outcomes after POEM.
