Clinical examination of the water-soluble vitamin levels in blood during peripheral parenteral nutrition.

The water-soluble vitamin (included vitamin B1, B6, B12 and C) preparations are not always replenished when peripheral parenteral nutrition (PPN) is used in Japan. We evaluated the need for administration of vitamins preparation during PPN, and involved analysis of the blood levels of water-soluble vitamins in patients receiving perioperative PPN before and after gastrectomy. Patients were examined as two set of groups as follows; 18 patients who did not receive water-soluble vitamin preparations during PPN, the Unsupplemented Group, and 22 patients who received such preparations during PPN, the Supplemented Group.

[A resected case of advanced gastric cancer after treatment with low-dosage TS-1].

We report a case of advanced gastric cancer that responded well to low-dosage TS-1. A 72-year-old woman was diagnosed as having unresectable advanced gastric cancer with ascites and hydronephrosis in the right kidney. She was treated with chemotherapy using a low-dosage of TS-1 (80 mg/body/day) administered perorally for 4 weeks followed by a drug-free 2 weeks, in six-week cycles.

Surgery and clinicopathological features of gastric adenocarcinoma involving the esophago-gastric junction.

To clarify the optimal operative procedure for gastric adenocarcinoma involving the esophago-gastric junction (EGJ), we investigated 49 cases with an upper gastric cancer invading the esophagus who underwent surgical treatment in our department during the period from 1991 to 2000. According to Siewert's classification, there were 21 cases with a type II tumor, and 28 cases with a type III tumor. Twenty-five cases underwent surgery through an abdominal approach only.

[Peritoneal dissemination of scirrhous type 4 gastric cancers].

We examined 198 cases of primary scirrhous type 4 gastric cancer at our department from 1984 to 2003. Of these, 139 cases underwent gastrectomy. The essential cause of inoperability was peritoneal dissemination with malignant abdominal abscises.

A patient with advanced gastric cancer, underwent curative gastrectomy and partial resection of metachronous hepatic metastases, is surviving for 13 years to date.

We have reported a successful case of curative partial liver resection of metachronous liver metastasis from advanced gastric cancer. The patient was 56 years old and has undergone total gastrectomy with D2 lymph node dissection (2 type, well-differentiated adenocarcinoma, H0P0n0se, Stage 2). At 18 months later, follow-up ultrasound detected liver metastasis in the right posterior segment.
