The aim of this study was to analyze the reasons and risk factors for intraoperative conversion from laparoscopic cholecystectomy to open cholecystectomy. The study involved 407 patients in whom laparoscopic cholecystectomy was planned between January 1998 and July 2006. The patients were divided into two groups (the LC completed group and the conversion(More)
Although percutaneous endoscopic gastrostomy (PEG) has become popular for patients with swallowing disorders as a nutrition support or a decompressant of gastrointestine, perioperative complications associated with PEG have not decreased, especially peristomal infections. To reduce peristomal infections, we designed a new method of gastrostomy by(More)
A 41-year-old Chinese woman was admitted to our hospital with epigastric pain. Computed tomography detected a heterogeneous enhancement tumor fed by the left gastroepiploic artery in the left lower quadrant and cholelithiasis. Excision of the tumor in the greater omentum and cholecystectomy were performed laparoscopically. Histological findings confirmed a(More)
BACKGROUND Tetracyclines such as doxycycline are reported to possess cytotoxic activity against mammalian tumor cells, but the mechanism of their effects on cell proliferation remains unclear. MATERIALS AND METHODS The antitumor effect of doxycycline was investigated in human pancreatic cancer cell line, PANC-1. We also investigated the effect of(More)
BACKGROUND/PURPOSE We provide an initial report of the indications and procedure for three-port laparoscopic partial hepatectomy. METHODS Three-port laparoscopic partial hepatectomy was performed in nine patients (age, 49 to 73 years) at our department. Eight patients (seven men and one woman) had hepatocellular carcinoma (HCC); six of these patients had(More)
BACKGROUND Although adjuvant gemcitabine (GEM) chemotherapy for pancreatic cancer is standard, the quality of life (QOL) in those patients is still impaired by the standard regimen of GEM. Therefore, we studied whether mild dose-intensity adjuvant chemotherapy with bi-weekly GEM administration could provide a survival benefit with acceptable QOL to the(More)
BACKGROUND Chemotherapy-induced nuclear factor kappaB (NFκB) activation is thought to play a key role in acquisition of chemoresistance by cancer cells. We focused on blockade of this activation by using the observation so-called 'desensitization' of NFκB using known NFκB activator, doxycycline. MATERIALS AND METHODS The human pancreatic cancer cell line(More)
We report a rare case of a huge cavernous hemangioma arising in a male breast. A 60-year-old man first noticed 1 x 2 cm elastic hard nodule just below his right nipple ten years previously. It enlarged 5 x 5 cm over six years. When he came to our clinic, it was size of child head (510 mm in circumference),was an elastic hard with a rather smooth surface,(More)
In order to investigate mechanisms underlying the occurrence of bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC), we analyzed results for 34 patients (0.59%; 17 men, 17 women; average age, 57 years) with BDI out of 5750 LCs, based on questionnaire responses from surgical operators, records of direct interviews with these operators,(More)
