Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: 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 Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
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:

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Surgical Oncology

Background:

  • The management of sinonasal and anterior skull base tumors has been revolutionized by endoscopic sinus surgery.
  • Endoscopic resection is increasingly recognized as the gold standard, even for extensive pathologies, offering an alternative to external approaches.

Purpose of the Study:

  • To describe the methodological differences enabling extended endoscopic surgery for sinonasal and anterior skull base tumors.
  • To highlight the unique skill set and considerations required for successful endoscopic tumor resection.

Main Methods:

  • Endoscopic tumor resection performed using an inside-out approach.
  • Specialized access techniques for challenging regions like the anterolateral maxilla and frontal sinus.
  • Structured vascular control and tailored cavity creation for sinonasal function preservation.

Main Results:

  • Endoscopic surgery provides equivalent or superior visualization compared to external operations.
  • This approach avoids significant morbidity associated with traditional open surgeries.
  • Successful resection requires specific surgical orientation and skills distinct from inflammatory disease surgery.

Conclusions:

  • Extended endoscopic surgery is a viable and effective approach for sinonasal and anterior skull base tumors.
  • Mastery of unique techniques, including vascular control and reconstruction, is crucial for optimal outcomes.
  • This method preserves sinonasal physiology and function, including the lacrimal apparatus, while minimizing patient morbidity.
