The aim of this review is to describe recent advances and topics in the surgical management of bile duct cancer. Radical resection with a microscopically negative margin (R0) is the only way to cure cholangiocarcinoma and is associated with marked survival advantages compared to margin-positive resections. Complete resection of the tumor is the surgeon's(More)
Diagnostic pneumoperitoneum, which has been considered the first step of any laparoscopic procedure, is no longer an absolute necessity. We devised an alternative to pneumoperitoneum or abdominal insufflation by upward and outward traction on the anterior abdominal wall with a “hanger lifting method” using subcutaneous wiring. Fairly good room was produced(More)
OBJECTIVE Postoperative pancreatic fistula (POPF) is a severe and frequent complication after pancreaticoduodenectomy (PD). The aim of this study was to identify an independent predictor of POPF and to assess the efficacy of preoperative multidetector row computed tomography (MDCT) images as an indicator for POPF. METHODS A total of 122 patients who(More)
BACKGROUND AND AIM The aim of this study was to investigate the diagnostic reliability of multidetector-row computed tomography (MDCT) for the evaluation of tumor spread in hilar cholangiocarcinoma. METHODS Images obtained from a 16-detector row scanner of 22 patients were interpreted. The diagnostic accuracy of longitudinal ductal spread, vertical(More)
Expression of tissue inhibitor of metalloproteinases (TIMP)-1 in colorectal cancer tissue is known to be related to disease progression; however, the clinical significance of measuring the blood level of TIMP-1, which we evaluate herein, has not yet been clarified. The serum level of TIMP-1 was measured by a one-step enzyme immunoassay in 123 patients who(More)
Abdominal wall lifting is a method to produce operative space between the anterior abdominal wall and the intra-abdominal organs during laparoscopic surgery. We devised a hanger lifting procedure for the anterior abdominal wall to avoid complications as well as reduce the costs related to the pneumoperitoneum. In our series, we performed 50 cases of(More)
Biliary reconstruction remains common in postoperative complications after liver transplantation. A systematic search was conducted on the PubMed database and 61 studies of retrospective or prospective institutional data were eligible for this review. The study comprised a total of 14,359 liver transplantations. The overall incidence of biliary stricture(More)
BACKGROUND Matrix metalloproteinase-9 (MMP-9) is one of the MMPs that play an important role in cancer invasion and metastasis. Increased levels of MMP-9 in tumor tissue have been found to correlate with advanced stages of colorectal cancer. However, the clinical significance of determining the levels of MMP-9 in blood samples from patients with colorectal(More)
Radical surgery for fulminant amoebic colitis leads to extremely high mortality; however, resective surgery is mandatory if a patient develops massive fecal peritonitis. We herein report an extremely rare case of fulminant amoebic colitis with multiple perforations, which was successfully treated by staged surgical procedures. A 48-year-old man who had been(More)
INTRODUCTION Liver hemangiomas are the most common benign liver tumors, usually small in size and requiring no treatment. Giant hemangiomas complicated with consumptive coagulopathy (Kasabach-Merritt syndrome) or causing severe incapacitating symptoms, however, are generally considered an absolute indication for surgical resection. Here, we present the case(More)
