まとめ
ハイブリッド最小侵入性食道切除 (HMIE) は,開いた食道切除 (OE) に比べて,管内死,肺炎,神経麻痺の割合が低いことを示しています. OEはアナストモティックとチール漏れが少ないかもしれません. 患者のプロフィールは,手術方法の選択を導くべきです.
科学分野:
- 腫瘍学
- 外科 胃腸科
- 医療技術
背景:
- 食道癌の治療は主に外科的切除に依存し,オープン食道切除 (OE) とハイブリッド最小侵入性食道切除 (HMIE) が主なアプローチである.
- OEとHMIEの安全性と有効性の比較は,現在も議論と研究の対象となっている.
研究 の 目的:
- 食道がんの管理におけるOEとHMIEの間での手術前および手術後の合併症を体系的に検討し,比較する.
- 食道がんの治療における手術戦略の最適化のための証拠に基づいた洞察を提供すること.
主な方法:
- Web of Science,EMBASE,PubMed,Scopus,Cochrane Libraryを含む主要なデータベースで包括的な文献検索が行われました.
- 6, 053人の患者を対象とした8つの研究のメタ分析は,確率比率 (OR) とリスク比率 (RR) を用いて95%信頼区間 (CI) で実施された.
主要な成果:
- HMIEは,血管死滅 (RR=3. 54),手術後の肺炎 (RR=1.29) および再発性喉頭神経麻痺 (RR=2.51) を著しく減少させた.
- 重篤な合併症 (Clavien- DindoグレードIIIa- IVbおよびV),出血,死亡率,または入院/ICUの長さの有意な違いは認められなかった.
- 開いた食道切除は,統計的に有意ではないが,アナストモティックおよびチール漏出率の減少傾向を示した.
結論:
- HMIEは管内死,肺炎,神経麻痺などの特定の合併症を軽減する利点があります.
- OEは,アナストモティックおよびチール漏れの発生率が低い可能性があります.
- OEとHMIEの選択は,患者の特徴に基づいて個別化し,長期的な腫瘍学的結果に関するさらなる研究が必要である.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
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 to...

Esophageal Perforation-II: Clinical Manifestations and Management
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.
Clinical Manifestations:
Clinical Manifestations:
Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

Endoscopic Procedures I: Esophagogastroduodenoscopy
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:
During an EGD, the endoscope can be used to:
Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
