Barrett Esophagus-II: Clinical Manifestations and Management

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...

Esophageal Achalasia

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...

Esophageal Strictures-II: Clinical Features and Management

Esophageal Strictures-II: Clinical Features and Management

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...

Area of Science:

Otolaryngology
Head and Neck Surgery
Oncology

Background:

Parapharyngeal tumors represent a rare subset (0.5%) of head and neck neoplasms.
Their diagnosis is challenging due to subtle symptoms and surgical inaccessibility.

Purpose of the Study:

To review clinical data of patients with parapharyngeal space tumors.
To analyze symptoms, diagnostic methods, surgical treatments, and histopathological findings.

Main Methods:

Retrospective analysis of 61 patients treated over 20 years.
Data collected from medical records including symptoms, diagnostic imaging (CT, MRI, angiography), surgical approaches, and pathology.

Main Results:

Common symptoms included dysphagia, foreign body sensation, and pain; some patients were asymptomatic.
Computerized tomography, MRI, and contrast angiography were crucial for localization.
Transcervical approach was most common, followed by transoral and combined methods.
Salivary and neurogenic tumors were the most frequent histopathological findings.

Conclusions:

Parapharyngeal tumors require advanced imaging for diagnosis.
Surgical management is standard, with transcervical approaches being prevalent.
Understanding common origins aids in diagnosis and treatment planning.
