Adenocarcinoma arising below an ileoanal anastomosis after restorative proctocolectomy for ulcerative colitis: report of a case.

We report a case of adenocarcinoma developing in remnant rectal mucosa below a hand-sewn ileal pouch-anal anastomosis (IPAA) after restorative proctocolectomy for ulcerative colitis (UC). To our knowledge, this is the first such case to be reported from Japan. A 60-year-old man with a 13-year history of UC underwent proctocolectomy with a hand-sewn IPAA and mucosectomy for anal stenosis and serious tenesmic symptoms.

[A case of femoral artery pseudoaneurysm occurring in the site of a reservoir port for hepatic arterial infusion].

A 73-year-old man underwent partial hepatic resection (55) for metachronous metastatic liver tumor from cecal cancer in November 2005. A reservoir port for hepatic arterial infusion (HAI) adjuvant chemotherapy was placed in the right femoral artery and the HAI chemotherapy was carried out. In January 2006, he had swellings of the right lower leg and inguinal region and was admitted to our hospital for a hematoma in the site of the reservoir port and deep venous thrombosis.

Constructing a local district telepathology network in Japan. Diagnosis of intraoperative frozen sections via telepathology over an integrated service digital network and the National Television Standard Committee System.

Objective: To construct a local telepathology network between the Department of Pathology, Tohoku University Hospital, and Koritu Kesennuma Hospital, about 150 km away.

Study Design: Tohoku University Hospital is connected with Koritu Kesennuma Hospital by an integrated service digital network for telepathology using the National Television Standard Committee system. The cases submitted for telepathology were limited to those in which a rapid intraoperative diagnosis was made on frozen sections.

The effects of vitamin K on the generation of des-gamma-carboxy prothrombin (PIVKA-II) in patients with hepatocellular carcinoma.

The clinical significance of des-gamma-carboxy prothrombin (PIVKA-II) in hepatocellular carcinoma (HCC) was investigated in 112 patients with and without vitamin K administration. The positivity rate of PIVKA-II was significantly decreased in patients receiving vitamin K (28.5%), compared with those without vitamin K administration (54.
