まとめ
肝細胞癌に対する選択的内放射線療法 (SIRT) は,肝臓手術後の胆漏れや呼吸器疾患のリスクを増加させる可能性があります. この研究は,肝切除手術前のSIRT後の潜在的な合併症を強調しています.
科学分野:
- 肝臓・胆管手術
- 介入放射線学
- 腫瘍学
背景:
- 選択的内部放射線療法 (SIRT) は,手術前の肝細胞癌 (HCC) のダウンステージ治療である.
- 肝切除手術後の合併症,特に胆道および呼吸器の問題に対するSIRTの影響については,さらなる調査が必要である.
- 一つの仮説は,SIRTは,特に腹膜に隣接する大きなHCC腫瘍の場合,胆道漏れおよび腹膜機能不全の発生率を高める可能性があるというものです.
研究 の 目的:
- HCC患者の右肝切除後のSIRTと術後の合併症の関連性を評価する.
- SIRT治療を受けた患者と,SIRT治療を受けていない患者との間で,胆道漏れおよび膜関連の合併症の発生率を比較する.
主な方法:
- 2015年1月から2022年12月までの間にSIRT後の右肝切除を受けたHCC患者で遡及研究が行われました.
- SIRTを投与された患者は,診断,手術,ASAスコア,CTPクラス,および腫瘍負荷に基づいて,SIRT以外の対照群と1対1に匹配された.
- 評価されたアウトカムには,リグレッションモデルを使用して分析された酸素依存症や膜関連合併症が含まれています.
主要な成果:
- SIRT群では,手術後の胆漏れ率が著しく高かった (40%対10%,OR=6,P<0. 05).
- SIRT群では,手術後の大きな膜出血が顕著に増加した (30%対0%,OR=10. 5,P<0. 05).
- 各グループには比較可能な20人の患者が含まれており,統計的に有意な相違が特定された.
結論:
- SIRTは,右肝切除術後の胆道漏出のリスク増加と関連している可能性があります.
- 肝臓手術後の呼吸道合併症の可能性も高まる可能性があることが示唆されています.

495
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...

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
