Endoscopic Procedures III: Video Capsule Endoscopy01:28

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

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: ERCP01:26

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.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Spinal Oncology

Background:

  • Minimally invasive surgery (MIS) is gaining traction for spinal intradural tumors.
  • Conventional microscopy/exoscopy can limit visualization of posterior root attachments for lobulated tumors.

Purpose of the Study:

  • To describe the utility of angled endoscopy in MIS for spinal intradural tumors.
  • To demonstrate improved visualization of tumor attachments using angled endoscopy.

Main Methods:

  • A minimally invasive right paraspinous approach was used.
  • Fenestration, lateral durotomy, and tumor delivery were performed.
  • Sharp dissection of radicular attachments under neuromonitoring and dural closure with oblique clips were utilized.

Main Results:

  • Gross-total extracapsular excision of a T10 nerve sheath tumor was achieved.
  • Angled endoscopy provided a panoramic view, facilitating visualization of tumor attachments.
  • The technique confirmed the totality of excision.

Conclusions:

  • Angled endoscopy is a valuable tool in MIS for spinal intradural tumors.
  • It improves visualization of tumor attachments, especially for large, multilobulated masses.
  • This enhances the ability to achieve complete tumor resection.
