[A Case of Neuroendocrine Carcinoma Originating from the Papilla of Vater].

A woman in her late 70s with fatigue, nausea, and epigastric discomfort was found to have a tumor at the papilla of Vater through endoscopy. We performed subtotal stomach-preserving pancreaticoduodenectomy with regional lymph node dissection. The immunohistological analysis showed positive staining for chromogranin A, synaptophysin, and CD56.

[Successful Experience of Negative Pressure Wound Therapy with Instillation and Dwelling(NPW Ti-d)for Patient with Wound Dehiscence Developed by Infection after Right-Hemicolectomy for Ascending Colon Cancer].

We report a case of infected and incised wound cured by negative pressure wound therapy with instillation and dwelling (NPWTi-d)after right hemicolectomy for ascending colon cancer. The patient was a 72-year-old male. An ascending colon cancer with abdominal wall invasion and enterocutaneous fistula was found.

[A case of long survival after resection and treatment with imatinib mesylate against metachronous liver metastases and a lung metastasis of a small intestine gastrointestinal stromal tumor].

A 68-year-old man was admitted to our hospital because of an abdominal tumor. Computed tomography(CT)showed a 6 cm tumor in the abdominal cavity. Surgery was performed.

[A case of organized chronic subdural hematoma showing an early recurrence after craniotomy].

A 64-year-old man who had undergone single burr hole drainage twice prior to this admission was hospitalized with a recurrent right chronic subdural hematoma. A head CT showed a mixed density subdural hematoma on the right frontotemporoparietal region. Based on the intraoperative findings of the previous surgeries, the hematoma was known to be organized.

[An elderly case whose residual malignant lymphoma was completely remitted by oral etoposide treatment using unusual dosing schedule].

In a 72-year-old man with malignant lymphoma (Hodgkin's disease, nodular sclerosis type, Stage III S), complete remission was induced by intravenous drip of adriamycin and oral administration of etoposide. After that, a maintenance dose of etoposide (25 mg) was administered every 3 days without observable side effects. From these results, we considered that the dose level and interval of administration are both important for chemotherapy in elderly patients.

Persistent primitive hypoglossal artery aneurysms--report of two cases.

The authors present two patients with subarachnoid hemorrhage caused by ruptured intracranial saccular aneurysms of the persistent primitive hypoglossal artery. A standard unilateral suboccipital approach in one patient resulted in incomplete neck clipping since the operative field was restricted by a protruding jugular tubercle. Successful aneurysmal neck clipping was achieved in the second patient via a unilateral-transcondylar-suboccipital approach with resection of the jugular tubercle and rim of the foramen magnum.

Endarterectomy for persistent primitive hypoglossal artery--case report.

Persistent primitive hypoglossal artery, an anastomosis between the carotid artery and the vertebrobasilar system, is found in about 0.05% of cerebral angiograms. Though usually asymptomatic, it may occasionally cause ischemic disease.
