まとめ
肝臓内胆管がん (ICC) の早期再発は,手術後に一般的であり,生存率の低下に関連しています. 重要な予測因子には,腫瘍の大きさ,多発焦点,リンパ節の広がり,血管の侵入,高いCA 19-9レベル,不完全な限界が含まれます.
科学分野:
- 肝臓・胆管の手術は,肝臓・胆管の手術として行われる.
- 外科腫瘍学の外科腫瘍学
- 胃腸内科 胃腸内科
背景:
- 肝臓内コレランジオカルシノーマ (ICC) は,発症率が上昇している肝臓がんの一種です.
- 手術の進歩にもかかわらず,切除後の高い再発率は,悪い結果につながります.
- 早期再発 (1年以内に) は,攻撃的な病気とより悪い予後を意味します.
研究 の 目的:
- 治癒性ICC切除後の早期疾患再発の特徴と予測要因を特定する.
- 術後のモニタリングとICC患者の補助療法選択を改善する.
主な方法:

- 早期再発は,手術後の12ヶ月以内に再発すると定義されます.
- 予測指標を決定するために使用されるコックス回帰モデル.
主要な成果:
- 患者の61%以上が再発し,再発の75%が早期発症でした.

Kidney Transplant II: Surgical Procedure
Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
