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...
Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
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...

Summary

Endoscopic third ventriculostomy (ETV) is a safe and effective treatment for obstructive hydrocephalus (OHC), offering high long-term shunt independence. This procedure provides a low-risk alternative to shunt placement, particularly beneficial in developing nations.

Area of Science:

  • Neurosurgery
  • Pediatric Neurosurgery
  • Neurology

Background:

  • Endoscopic third ventriculostomy (ETV) is a widely adopted first-line treatment for obstructive hydrocephalus (OHC).
  • Experience with ETV in managing OHC has been accumulating since 1998.
  • This report details the authors' experience with ETV for OHC management.

Purpose of the Study:

  • To evaluate the efficacy and safety of ETV in treating obstructive hydrocephalus.
  • To assess long-term outcomes, including shunt independence rates.
  • To identify potential predictors of ETV failure.

Main Methods:

  • A retrospective review of medical records for 46 patients who underwent 49 ETV procedures for OHC between 1998 and 2007.
  • Success was defined as achieving shunt-free survival.
  • Kaplan-Meier analysis was used to determine shunt-free survival rates.

Main Results:

  • The study included 46 patients (29 males, 17 females) with a mean age of 23 years.
  • Aqueductal stenosis and tectal tumors were the most frequent causes of OHC (63%).
  • Initial ETV failure occurred in 7 patients (15.6%). Among those with initial success, 76.3% achieved shunt independence after a mean follow-up of 37 months, with a 5-year shunt-free survival rate of 70%. No variables predicted ETV failure. Transient complications occurred in 13% of patients, with no ETV-related deaths or permanent morbidity.

Conclusions:

  • ETV is a safe and effective treatment for OHC, yielding a high rate of long-term shunt independence.
  • The procedure carries a low risk of complications.
  • ETV should be considered the preferred treatment for OHC, especially as a substitute for shunt placement in neurosurgically developing countries.
