We report a rare case of Crohn disease accompanied by a small-bowel carcinoma that developed in a 54-year-old Japanese man. The ulcerating tumor, which histologically proved to be a poorly differentiated adenocarcinoma and dysplasia surrounding the carcinoma, was located in the diseased ileum. The Ki-67 immunoreactive epithelial cells were increased in(More)
BACKGROUND/AIMS The long-term outcome of laparoscopic resection (Lap-R) of rectal cancer is still unclear. The purpose of this study was to elucidate the validity of Lap-R by comparing the short-term and mid-term outcome of Lap-R performed in our hospital to treat T1 and T2 rectal cancer patients with that of patients with the same clinicopathological(More)
BACKGROUND/AIMS Although after laparoscopic surgery for colorectal cancer postoperative recovery is better than after open surgery, oncologic outcome after this minimally invasive technique remains unclear. In this study we tested the null hypothesis that there is no difference in the outcome of advanced colorectal cancer according to whether it is treated(More)
We report a 70-year-old male who had biloma as an early complication of hepatic artery infusion chemotherapy. The patient had a history of subtotal gastrectomy for a advanced gastric cancer. Two years after the primary operation on the stomach, a solitary metastatic liver tumor was indicated by follow-up abdominal CT, and a segmental hepatectomy was(More)
BACKGROUND/AIMS We present herein the three-dimensional reconstruction of colorectal tumors, with particular reference to growth pattern into each layer of the colorectal wall, and measurement of tumor volume and surface area. METHODOLOGY Conventional tissue section images of colorectal tumors were analyzed using a computer graphics analysis program. The(More)
Ion species ratio of high current positive hydrogen/deuterium ion beams extracted from an electron-cyclotron-resonance ion source for International Fusion Materials Irradiation Facility accelerator was measured by the Doppler shift Balmer-α line spectroscopy. The proton (H(+)) ratio at the middle of the low energy beam transport reached 80% at the hydrogen(More)
The objective of linear IFMIF prototype accelerator is to demonstrate 125 mA/CW deuterium ion beam acceleration up to 9 MeV. The injector has been developed in CEA Saclay and already demonstrated 140 mA/100 keV deuterium beam [R. Gobin et al., Rev. Sci. Instrum. 85, 02A918 (2014)]. The injector was disassembled and delivered to the International Fusion(More)
Prophylactic intra-arterial infusion of anticancer drug on post hepatic resection for hepatic metastasis of colorectal carcinoma were performed 8 cases. In our cases consisted of 8 patients of mean age of 54.3 years (male 3 cases and female 5 cases, synchronous metastasis 4 cases and metachronous 4 cases). All patients were received intra-arterial bolus(More)
