まとめ
中性粒子のリンパ球比 (NLR) は,急性胆炎 (AC) の合併症を予測することができます. 高値のNLRは,腹腔鏡による胆管切除術 (LC) の後の緊急入院,エンピエマ,長期滞在のリスクの増加と相関しています.
科学分野:
- 胃腸内科
- 手術腫瘍学
- 炎症マーカー
背景:
- 急性胆炎 (AC) は手術が必要で,標準的な治療法は腹腔鏡による胆切除術である.
- 中性粒子のリンパ球比 (NLR) は全身の炎症を定量化し,胃腸疾患の予後ツールです.
- NLRがACの重症性を診断し予測する際の 潜在的有用性は調査に値する.
研究 の 目的:
- 急性胆小板炎 (AC) を診断した患者の中性粒子のリンパ球比 (NLR) の予後的意義を評価する.
- NLRがACに関連した重症性と合併症を予測できるかどうかを判断する.
主な方法:
- 急性胆囊炎 (AC) に対して,腹腔鏡による胆囊切除 (LC) を受けた306人の患者の遡及分析.
- 術前検査 (白血球数,ビリルビン),入院タイプ (緊急/選択),手術中の合併症 (穿孔,エンピエマ),手術期間,入院.
- 中性粒子のリンパ球比 (NLR) と臨床結果の相関
主要な成果:
- ニュートロフィール対リンパ球比 (NLR) が5を超えると,緊急入院率が高かった.
- NLRの上昇は,エンピエマの危険性,ビリルビンの濃度の上昇,手術および入院期間の延長と相関していた.
- NLRと胆囊の穿孔,または患者の性別との間に有意な関連性は見つかりませんでした.
結論:
- ニュートロフィール対リンパ球比 (NLR) の値上昇は,急性胆炎 (AC) の合併症のリスクを高めることを示す.
- NLRは重度の胆炎を特定し,患者の管理に役立つ貴重な臨床予測因子です.

Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Appendicitis-II: Diagnostic Studies and Management
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
