Abstract Survival time of 73 patients with undiagnosed gallbladder carcinoma incidentally found after cholecystectomy treated between 1982 and 2000 was evaluated in relation to various variables, with special reference to the significance of the radical second resection. The most significant prognostic factor was the depth of tumor invasion as assessed by(More)
p < 0.05). It should be noted that a certain proportion of duct stones may be missed by selective ERC, necessitating laparotomy when sphincterotomy fails. The routine use of preoperative ERC may be justified at institutions where the expertise is available, at least until laparoscopic lithotomy becomes easy.
PURPOSE autoimmunity has been proposed as one of the pathogenesis of abdominal aortic aneurysm (AAA). There is also a likelihood that when aorto-iliac occlusive disease (AIOD) coexists with AAA, some other occlusive atherosclerotic diseases, such as ischemic heart disease and cerebrovascular disease, may develop, leading to a very poor long-term prognosis.(More)
BACKGROUND/AIMS Single-incision laparoscopic cholecystectomy (SILC) is a promising alternative to standard multi-incision laparoscopic cholecystectomy (LC). However, generalization of SILC is still hampered by technical difficulties mainly associated with the lack of trocars used for retraction of the gallbladder. We therefore developed a modified method of(More)
CASE A 75-year-old man was admitted for anemia, and a tar stool found by endoscopic examination revealed a type 3 advanced gastric cancer in the lower stomach. Multiple liver metastases 4 cm in diameter were shown on CT. Because we thought that the case was unresectable, S-1/CPT-11 chemotherapy was performed. S-1 (80mg/body/day) was orally administered for(More)
The name of gastritis was introduced by Broussais in 1808. He considered it as the seat of febrile diseases such as typhoid fever. However, what he had seen was soon proved to be a postmortem change and the name of gastritis was discarded for some time. Nevertheless the presence of inflammatory change of the gastric mucosa was gradually recognized with the(More)
Ten intact wrist joints were examined to evaluate the hamate hook visualisation by a hamate hook lateral radiographic view. Results of the study indicated that this 30 degrees -tilted lateral wrist radiographic projection with palmar abduction of the thumb clearly revealed the hamate hook from its base to the tip in the first web space away from the(More)
