Recently, some studies have suggested that sentinel node biopsy also can be applied to gastric cancer. The authors apply sentinel lymph node biopsy in laparoscopy assisted distal gastrectomy to perform it as safe limited surgery. Limited surgery is a procedure in which the extent of lesion resection and lymph node dissection is reduced. The authors(More)
In April 2006, a 70-year-old man who had undergone a subtotal gastrectomy with Billroth II reconstruction for a benign peptic ulcer in 1955 and cholecystectomy for gallstones in 2005 was admitted to our hospital complaining of abdominal pain, distention and vomiting. Physical examination showed a large cystic abdominal mass with tenderness in the(More)
In esophageal squamous cell carcinoma (ESCC), chemoradiotherapy (CRT) has a curative potential even in cases of locally advanced carcinoma. However, only about half of the patients benefit from CRT, and an accurate prediction of sensitivity to CRT is eagerly awaited. Using microarrays, we analyzed gene-expression patterns of pretreatment biopsy specimens(More)
BACKGROUND/AIMS The present study was conducted to investigate the relationship between bone metabolic disorder after gastrectomy for gastric cancer and vitamin D metabolites or the hormones involved in calcium metabolism. METHODOLOGY Twenty-one patients who had undergone gastrectomy for gastric cancer and had been followed for less than 10 years were(More)
We report the successful management of multiple small-bowel perforations caused by cytomegalovirus (CMV) infection in a 60-year-old man, 1 day after CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) therapy induction for malignant lymphoma. Emergency laparotomy was performed for perforative peritonitis, but we did not resect the lesions at this(More)
BACKGROUND Surgical samples have long been used as important subjects for cancer research. In accordance with an increase of neoadjuvant therapy, biopsy samples have recently become imperative for cancer transcriptome. On the other hand, both biopsy and surgical samples are available for expression profiling for predicting clinical outcome by adjuvant(More)
BACKGROUND/AIMS We investigated whether sentinel lymph node biopsy using dye technique alone is useful or not in decision-making for less invasive surgery in patients with gastric cancer. METHODOLOGY The subjects were 43 patients who had undergone laparotomy for gastric cancer and consented to undergo sentinel lymph node biopsy using patent blue dye. The(More)
nosed segment III infarction due to liver abscess, because CT scan showed the cluster sign characteristic of a liver abscess [1, 2] . We performed an operation for lavage and drainage ( fig. 2 ). Nine days later, CT examination revealed that the abscess cavity had become smaller and the infarction area had a transformed abscess ( fig. 1 b). Five months(More)
BACKGROUND/AIMS In this study, we performed 13C-urea breath test in patients who had undergone total gastrectomy and investigated the content of (13)CO2 in the CO2 gas expired after direct influx of 13C-urea into the small intestine. METHODOLOGY 13C-Urea breath test was performed in 31 patients who had undergone total gastrectomy at this department for(More)
OBJECTIVE We investigated change in platelet activation using flow cytometry in patients before and after splenectomy with total gastrectomy for gastric cancer. METHODS Six patients who underwent splenectomy for lymphadenectomy with total gastrectomy for gastric cancer were the subjects in this study. In the patients, platelet count and platelet(More)
