BACKGROUND This study examined the feasibility of early laparoscopic cholecystectomy (ELC) for acute cholecystitis (AC) according to the Tokyo guidelines severity grade, and analyzed the changes in the therapeutic strategy for AC after the Tokyo guidelines were published. METHODS A total of 225 patients were enrolled in this study. The therapeutic period(More)
This report presents the case of a common hepatic artery (CHA) pseudoaneurysm secondary to postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD), which was successfully treated using a coronary covered stent. A 70-year-old female underwent subtotal stomach-preserving PD for middle cholangiocarcinoma. POPF was identified on postoperative(More)
Studies on human cell hybrids between a cervical carcinoma cell line, HeLa, and normal fibroblasts have indicated that their tumorigenicity is under the control of a putative tumor suppressor on chromosome 11. We have previously demonstrated that a tumorigenic cell hybrid CGL4 expresses a larger glucose transporter, GLUT1, due to altered glycosylation when(More)
BACKGROUND AND STUDY AIMS Palliative treatment for duodenal stenosis with an enteral stent is effective in enhancing the quality of life of patients with duodenal obstruction. There have been no thorough comparisons of duodenal stent placement with standard surgical gastrojejunostomy. The present study evaluated the outcome of duodenal stent placement and(More)
BACKGROUND The use of a self-expandable metallic stent (SEMS) has emerged as an alternative treatment option for malignant colorectal obstruction. Although the technical success rate of SEMS has been widely reported, outcome data are limited. METHODS This retrospective study evaluated the short- and long-term outcomes of colorectal SEMS for malignant and(More)
BACKGROUND In patients with gastric outlet obstruction (GOO), palliative enteral stenting is a less invasive procedure compared with gastroenterostomy. Most diseases analyzed in previous studies of such stenting were pancreaticobiliary malignancies. METHODS We reviewed the medical records of patients with GOO secondary to gastric cancer who were admitted(More)
PURPOSE Purpose of this study was to assess stent endoprosthesis for colorectal cancer (SECC) as an adjuvant to operative preparation in patients with obstructing colorectal cancers. METHODS A self-expanding stainless steel stent was inserted in 15 patients with obstructing colorectal cancers under colonoscopic observation and fluoroscopic control.(More)
PURPOSE Expandable metallic stent endoprosthesis for preoperative "bridge to surgery" treatment of obstructive colorectal cancer has been broadly, clinically used with good short-term results. Stent insertion for malignant tumor, however, is controversial because of the increased risk of metastasis, invasion, and advancement of the cancer. We, first in the(More)
PURPOSE The aim of this retrospective study was to identify the risk factors associated with the severity characteristics in the Tokyo guidelines for conversion to open surgery in patients with acute cholecystitis (AC) who underwent laparoscopic cholecystectomy. METHODS A total of 225 patients were enrolled in the study. The patients were classified into(More)
BACKGROUND We performed bacteriological analysis of bile in acute cholecystitis (AC) patients graded in severity according to the Tokyo guidelines. METHODS We enrolled 163 AC patients in whom bacteriological analysis of bile was performed. RESULTS Significant differences in age (60 vs. 67 years), body temperature (BT) (37.2 vs. 37.6°C), white blood cell(More)
