- 画像検出技術を用いた内視鏡仮想リール (EVR) の開発と検証.
- EVRは,内視鏡治療の前に病変の大きさの客観的な測定を提供することを目的としています.
- 内視鏡の病変評価の正確性と安全性を高めるために.
主な方法:
- EVRは,コンピュータ画像認識とレーザースポット画像の原理を使用して開発されました.
- EVRの正確性と安全性を検証するために,インビトロおよび臨床実験が行われました.
- EVRの測定は,実際の病変のサイズと,内視鏡医の視覚的な見積もりと比較した.
主要な成果:
- EVRは,最小の誤差 (0.08 ± 0.17cm) で,高精度 (92.80% ± 5.50%) をインビトロで実証しました.
- 臨床環境では,EVR (85.68% ± 15.25%) は視覚的な推定 (67.08% ± 22.59%) よりも有意に正確でした.
- EVRは,改善された有効性,一貫性,および誤った分類率の減少を示し,報告された副作用はありません.
結論:
- エンドスコピック・バーチャル・ライラー (EVR) は,病変の大きさを測定するための正確で安全で客観的なツールです.

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...

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:

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Procedures V: ERCP
3.8K
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.

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...
