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.

Colonic varices treated with embolization after pancreatoduodenectomy with portal vein resection: a case report.

Background: Pancreatoduodenectomy with resection of the portal vein or superior mesenteric vein confluence has been safely performed in patients with pancreatic head cancer associated with infiltration of the portal vein or superior mesenteric vein. In recent years, left-sided portal hypertension, a late postoperative complication, has received focus owing to increased long-term survival with advances in chemotherapy. Left-sided hypertension may sometimes cause fatal gastrointestinal bleeding because of the rupture of gastrointestinal varices.

Minimally invasive surgery for esophageal cancer after esophageal perforation.

Both esophageal rupture and esophageal cancer are life-threatening diseases. We report a case of esophageal cancer that occurred after esophageal rupture was treated with thoracoscopic and laparoscopic surgery. A 76-year-old man presented with vomiting followed by epigastric pain and was diagnosed with spontaneous esophageal rupture.

Subcarinal node is the significant node that affects survival in resected small cell lung cancer.

Purpose: Our aim was to clarify the significance of surgery and the prognostic factors in patients with small cell lung cancer (SCLC).

Method: A retrospective review of 50 patients with limited SCLC who underwent a pulmonary resection and mediastinal nodal dissection during the 10-year period from 1988 to 1997 was undertaken. The TNM classification was applied to all cases of SCLC.

Successful resection of a recurrent mediastinal liposarcoma invading the pericardium: report of a case.

Primary liposarcoma of the mediastinum is rare, but cases of recurrence have been reported in the English literature. We successfully resected a recurrent pericardial liposarcoma, detected 5 years after the initial resection of a liposarcoma of the anterior mediastinum invading the pericardium. Routine follow-up computed tomography showed the recurrence and suggested invasion of the pericardial cavity, which was supported by the findings of transesophageal ultrasonography.

Wedge resection of the portal bifurcation concomitant with left hepatectomy plus biliary reconstruction for hepatobiliary cancer.

Background/purpose: We report our experience performing wedge resection of the portal bifurcation and transverse suture closure in patients undergoing left hepatectomy and caudate lobectomy plus biliary reconstruction for hepatobiliary cancer.

Methods: The procedure was performed in three patients with hilar or intrahepatic cholangiocarcinoma. After confirming that tumor invasion of the portal bifurcation was not circumferential, the portal trunk and the right posterior and right anterior portal branches were isolated and clamped.

Spontaneous pneumothorax secondary to radiographically occult lung metastasis from parapharyngeal synovial sarcoma: report of a case.

This report describes a case of secondary pneumothorax caused by a radiographically occult lung metastasis from parapharyngeal synovial sarcoma, a relatively rare tumor known to be highly metastatic to the lung. Although chest X-ray and thoracic computed tomography scan failed to detect the metastatic nodule in the right lung, the surgically resected specimen proved to be a 3-mm lung metastasis. To our knowledge, only eight cases of lung metastases from synovial sarcoma causing pneumothorax have ever been reported.
