Abstract:
Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) may be employed for procurement of a tissue diagnosis in a minimally invasive fashion. In many cases, EUS-FNA excludes the need for more invasive diagnostic procedures when a tissue diagnosis is required. In patients with esophageal neoplasms, EUS-FNA is a safe and accurate tool for the preoperative diagnosis of metastatic spread to the paraesophageal and celiac lymph nodes. EUS-FNA is also increasingly recognized as an accurate, cost-effective and safe means of evaluating and staging patients with lung cancer. EUS-FNA is useful in providing tissue confirmation of cancer in cases in which bronchoscopy or computed tomography-guided approaches has been non-diagnostic. EUS-guided therapies are paving the way for therapeutic/interventional EUS. The interventional endoscopist will now play a more central role in the diagnosis and treatment of various gastrointestinal malignancies by delivering antitumor agents.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
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.
