科学分野:
- 胃腸内科 胃腸内科
- エンドスコピーは,内視鏡検査です.
- 腫瘍学 腫瘍学
背景:
- 食道腺がん (EAC) の発生率は上昇しており,バレット食道 (BE) が主要な前駆体となっている.
- 内視切除 (ER) は,BEの目に見える病変の標準であり,ステージと治療を提供しています.
- ERは,不形成症と初期段階のEACの管理に不可欠です.
研究 の 目的:
- BEの病変について,内視粘膜切除 (EMR) と内視粘膜下解剖 (ESD) を比較してください.
- 臨床実務における最適なERテクニックの選択を明確にします.
- 特定のシナリオにおける比較証拠の欠如に対処する.
主な方法:
- 現在のERテクニックのレビュー:EMRとESD.
- 病変の大きさ,形状,および治療決定における下粘膜の侵入の分析.
- ERアプローチに関するコンセンサスがない臨床シナリオの特定.
主要な成果:
- EMRは,より小さな,表面的な病変に安全で効果的ですが,より大きな病変では断片的な切除を必要とします.
- ESDは,サイズに関係なくエンブロック切除を可能にしますが,より長い処置期間で技術的に要求されています.
- 特定のケース (例えば,侵入の疑い,線維症) でESDについてコンセンサスが存在し,EMRは他のケースでは標準です.
結論:
- 特定のBE関連病変に対する最適なERテクニックに関して,重要な知識のギャップが存在します.
- 治療決定を導くためにさらなる比較研究が必要である.
- ERの徴候の明確化は,BE管理における患者のアウトカムを改善します.

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.

Barrett Esophagus-I: Introduction
976
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

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:
