AIM Percutaneous radiofrequency ablation (P-RFA) therapy is a widely applied treatment for small hepatocellular carcinoma (HCC); however, local recurrence is a major issue of HCC located at the surface of the liver (surface HCC). The aim of this study was to compare the outcome of laparoscopic hepatic resection (LH) and P-RFA for surface HCC in case-control(More)
We evaluated the preoperative and postoperative characteristics and prognosis of super-elderly patients with hepatocellular carcinoma (HCC). Four hundred and thirty-one patients who underwent hepatic resection for HCC were classified into three groups according to their age at the time of surgery: super-elderly (≥80 years; n = 20), elderly (70–80 years; n =(More)
A case of spontaneous peripelvic extravasation associated with ureteral stenosis caused by retroperitoneal lymph node metastasis of the ascending colon cancer is reported. A 47-year-old woman complained of colic on right costa-vertebral angle. Excretory urograms showed right peripelvic extravasation and CT-scan showed urinoma formation around right kidney.(More)
AIM   Several investigators have shown that interferon (IFN) therapy can suppress the recurrence of hepatocellular carcinoma (HCC) after curative treatment. We investigated the effect of IFN therapy on the first and second HCC recurrence following hepatic resection of hepatitis C virus (HCV)-related HCC. METHODS   Subjects included 166 patients who had(More)
BACKGROUND An outbreak of cholangiocarcinoma occurred among workers in the offset color proof-printing department at a printing company in Japan. The aim of this study was to clarify the characteristics of the patients with cholangiocarcinoma. METHODS This was a retrospective study conducted in 13 Japanese hospitals between 1996 to 2013.

BACKGROUND Cholangiocarcinoma has been reported in workers exposed to chlorinated organic solvents and has consequently been classified as an occupational disease (occupational cholangiocarcinoma) by the Japanese Ministry of Health, Labour and Welfare. This study aimed to identify the characteristics of nine workers newly diagnosed with occupational(More)
OBJECTIVES A cholangiocarcinoma outbreak among workers of an offset color proof-printing department in a printing company was recently reported. It is important to understand the clinical course leading to occupational cholangiocarcinoma development for investigation of the carcinogenesis process and for surveillance and early detection. We evaluated the(More)
For safe and effective laparoscopic surgery it is important to maintain a favorable view of the operative field. However, the use of a conventional liver retractor needs an additional wound and carries a risk for liver injury during surgery. We developed a novel retraction technique for the lateral lobe of the liver using a silicone disk (Hakko Co. Ltd.)(More)
This study aimed to establish an efficient strategy for screening and surveillance for occupational cholangiocarcinoma. We evaluated the consecutive changes in laboratory findings during regular health examinations and in abdominal ultrasonography findings before the diagnosis of occupational cholangiocarcinoma in nine patients. The results of laboratory(More)
INTRODUCTION Gastrojejunocolic fistula is a rare condition after gastrojejunostomy. It was thought to be a late complication related to stomal ulcers as a result of inadequate gastrectomy or incomplete vagotomy. We report a case of gastrojejunocolic fistula after gastrojejunostomy for peptic ulcer treated with one-stage laparoscopic resection. CASE(More)
