Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Summary

This summary is machine-generated.

Endoscopic orbital exenteration offers a minimally invasive alternative for treating orbital tumors and fungal infections. This technique preserves key orbital tissues, reducing recovery time and the need for grafts.

Area of Science:

Ophthalmology
Otorhinolaryngology
Surgical Oncology

Background:

Orbital exenteration is a surgical procedure to remove orbital contents.
Traditional methods include external eyelid-sparing or eyelid-sacrificing approaches.
An alternative endoscopic technique is presented to improve outcomes.

Purpose of the Study:

To describe an alternative endoscopic technique for orbital exenteration.
To highlight the specific advantages of this novel approach over traditional methods.

Main Methods:

Retrospective analysis of three patients at a tertiary care center.
Patients had sinonasal malignancy or invasive fungal sinusitis with intraconal involvement.
Advanced endoscopic techniques, image guidance, and soft-tissue shaver technology were employed.

Main Results:

Successful eyelid-sparing endoscopic orbital exenteration in all three patients.
Procedure completed within 30-45 minutes with minimal blood loss.
Preservation of superior and lateral orbital periosteum allowed for cavity mucosalization within 8 weeks.

Conclusions:

Endoscopic power-assisted orbital exenteration is an effective technique.
Key advantages include direct transnasal control of the ophthalmic artery and preservation of periorbita.
This approach facilitates mucosal coverage, minimizes blood loss and operative time, and may be crucial for managing orbital tumors and fungal sinusitis.
