[A Case of Jejunal Ectopic Pancreatic Cancer with Small Bowel Obstruction].

Were port a caseof an 82-year-old man who presented with vomiting. Computed tomography(CT)revealed a jejunum tumor and small bowel obstruction. Enteroscopy revealed a protruded lesion and biopsy indicated adenocarcinoma.

[A Case Report--A Synchronous Liver Metastasis from Gastric Cancer Treated with Chemotherapy, Surgical Resection of the Gastric Cancer, and RFA of the Liver Metastasis].

A 71-year-old man was admitted to our hospital because of abdominal pain. An upper gastrointestinal endoscopy revealed a type 3 tumor in the lesser curvature of the gastric body. A computed tomography (CT) scan showed synchronous liver metastasis in liver S6 and S8, and a large 8a lymph node that could be encased within the common hepatic artery.

[Effect of tolvaptan on ascites due to malignancy].

Ascites accompanying a malignancy is often refractory to conventional treatment with saline diuretics, making it difficult to control. We administered a new diuretic, Tolvaptan, to 10 individuals with malignancy and heart failure accompanied by ascites, which was refractory to saline diuretics, and assessed its efficacy and adverse events. We observed a significant reduction in abdominal distension following 2 weeks of Tolvaptan administration.

Protective effects of simultaneous splenectomy on small-for-size liver graft injury in rat liver transplantation.

Splenectomy is an effective technique in living donor liver transplantation (LDLT) with small-for-size (SFS) liver grafts for overcoming SFS liver graft injury. However, the protective mechanism of splenectomy is still unclear. The aim of this study was to investigate how splenectomy could attenuate SFS graft injury through the measurement of biochemical factors, particularly the expression of endothelin (ET)-1, which is a key molecule of microcirculatory disorders by mediating sinusoidal vasoconstriction.

Breast cancer with cartilaginous and/or osseous metaplasia.

We report a rare case of breast cancer with cartilaginous and/or osseous metaplasia. A 59-year-old woman had a large lump in her left breast, which had enlarged gradually over a period of 2 years. Mammography, ultrasonography and aspiration cytology suggested phyllodes tumor with carcinoma.
