Spontaneous intercostal artery bleeding occurring simultaneously in numerous vessels during antithrombotic therapy with mechanical circulatory support: a case report.

Background: Intercostal artery bleeding often occurs in a single vessel; in rare cases, it can occur in numerous vessels, making it more difficult to manage.

Case Presentation: A 63-year-old Japanese man was admitted to the emergency department owing to sudden chest and back pain, dizziness, and nausea. Emergency coronary angiography revealed myocardial infarction secondary to right coronary artery occlusion.

Metastatic lung tumor from hepatocellular carcinoma with tumor thrombus invasion in the pulmonary vein: a case report.

Background: Metastatic lung tumor with a tumor thrombus in the peripheral pulmonary vein is very rare. We present a case of a metastatic lung tumor from hepatocellular carcinoma (HCC) with tumor thrombus invasion in the pulmonary vein that was diagnosed preoperatively and underwent complete resection by segmentectomy.

Case Presentation: A 77-year-old man underwent laparoscopic lateral segment hepatectomy for HCC eight years ago.

Hepatocellular carcinoma with regional lymphadenopathy caused by sarcoid-like reaction: a case report.

Background: Sarcoid-like reaction (SLR) is a histological pattern of granulomatous inflammation that is clinically differentiated from sarcoidosis. Since SLR is known to occur in several neoplasias and occasionally causes lymphadenopathy and mimics metastatic malignancy, it needs to be considered whether lymphadenopathy is due to metastasis or SLR for the choice of cancer treatment. Few cases of hepatocellular carcinoma (HCC) with SLR have been reported.

[Bronchial Stump Coverage Technique by da Vinci Xi].

da Vinci's greatest attractions are the fine images acquired with a high-resolution 3-dimensional( 3D) endoscope and the precise operation by forceps equipped with an articulated arm. We believed that complicated procedures can benefit from robot-assisted surgery. We have been actively performing collection and sewing of viable tissue using da Vinci Xi for the purpose of preventing bronchial stump fistulas.
