Insights

A swallowed patency capsule caused breathing difficulties in a patient. Flexible bronchoscopy successfully removed the capsule intact, preventing airway inflammation from its barium contents.

Area of Science:

  • Gastroenterology
  • Pulmonology
  • Medical Device Safety

Background:

  • A 77-year-old male patient presented with anemia, history of abdominal surgeries for colon and gastric cancer.
  • Investigating anemia via endoscopy, the patient swallowed a patency capsule.

Observation:

  • Post-swallowing, the patient experienced acute dyspnea.
  • Imaging (chest radiography and CT scan) confirmed patency capsule aspiration into the bronchus intermedius.

Findings:

  • Successful retrieval of the patency capsule was achieved using flexible bronchoscopy.
  • A specialized technique involving a balloon catheter prevented capsule deformation during removal.
  • This method ensured the capsule remained intact, preventing barium leakage into the airway.

Implications:

  • Highlights the risk of patency capsule aspiration into the tracheobronchial tree.
  • Demonstrates an effective endoscopic technique for safe, non-deformed capsule removal.
  • Emphasizes the importance of prompt intervention to prevent barium-induced airway inflammation.

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,...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

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...
