まとめ
食道ステントは自発的な穿孔に対して高い成功率 (86. 1%) を示しています. エンドスコピーによる真空療法 (EVT) も有望である (89. 6%の感受性後の分析),しかしさらなる試験が必要である.
科学分野:
- 胃腸科と外科
- 最低侵襲的処置
- 食道疾患
背景:
- ボアハーブ症候群の自発的な食道穴は,著しい罹病率と死亡率のリスクを伴います.
- 食道ステントと内視真空療法 (EVT) などの最小侵襲的な治療法がますます利用されています.
- 食道欠陥の最適な管理戦略はまだ研究中です.
研究 の 目的:
- 食道ステントとEVTの有効性と安全性を体系的に検討し,メタ分析する.
- 密封率,失敗率,そしてこれらの介入に関連する死亡率を評価する.
- 食道障害の管理における食道ステントとEVTの結果を比較する.
主な方法:
- PubMed,Scopus,Cochrane Libraryで広範な文献検索が行われました
- 対象となった研究は観察的および症例シリーズで,食道ステントとEVTに焦点を当てました.
- 主なアウトカムには,ランダム効果モデルを使用して分析された,統合された封印率,失敗率,および死亡率が含まれています.
主要な成果:
- 食道ステント試験 (245人の患者) では,閉塞率は86. 1%,失敗率は14. 9%,ステント関連死亡率は7. 4%と報告されました.
- 初期EVT研究 (424人の患者) は,高異質性で54. 1%のシール化率を示した.
- 感受性分析後,EVTの密封率は89. 6%に増加した.
結論:
- 食道ステントとEVTの両方が食道欠陥の閉塞に有効であることが示されています.
- 食道ステントは確立された役割を持ち,EVTは初期異質性にもかかわらず潜在性を示しています.
- 食道穴の管理のための証拠に基づいたガイドラインを確立するために,さらなるランダム化制御試験が不可欠です.

Esophageal Perforation-II: Clinical Manifestations and Management
146
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

Esophageal Strictures-I: Introduction
264
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
