We fabricated a stainless-steel over-tube for rapid and simple insertion of a T-tube following common bile duct exploration during laparoscopic surgery. With this over-tube, operating time is greatly shortened because minimal incision and only two sutures are needed to prevent bile leakage.
BACKGROUND Xanthogranulomatous lesion is a rare condition that can develop in the gall bladder, kidney, and retroperitoneal space. This lesion is an inflammatory disease. It is commonly accepted that Xanthogranulomatous lesion of the pancreas (XGP) is hardly distinguishable from pancreatic neoplasms. As a result of the similarity of pancreatic cancer in… (More)
BACKGROUND Tumor thrombus in the portal vein is a common complication of hepatocellular carcinoma, but an extremely rare complication of common bile duct cancer. CASE PRESENTATION A 78-year-old woman was referred to our department because of jaundice. Laboratory data showed severe liver dysfunction with high serum levels of total bilirubin and CA19-9.… (More)
A clear field of vision during laparoscopic cholecystectomy was attained by using a newly designed retractor which elevates the abdominal wall and does not require high-pressure CO2 infusion into the peritoneal cavity. As the abdominal cavity is continuously ventilated, smoke from the cauterization is suctioned off through openings in the middle part of the… (More)
Between April and August 1991, 83 Japanese patients with symptomatic gallstones underwent laparoscopic cholecystectomy in our clinics. A prospective randomized trial was carried out to examine the safety, efficacy, and complications of the two techniques, pneumoperitoneum vs an elevating method using a U-shaped retractor. Forty-two patients were randomly… (More)
Osteoporosis after gastrectomy is a common clinical disorder. In gastrectomized patients, decreased gastric acidity may be associated with impaired calcium absorption. This study was undertaken to determine whether patients with chronic use of H2-receptor antagonists (HRA) had demonstrable decreases in bone mineral density (BMD). Thirty-three patients… (More)
We developed a modified dissector capable of carrying out a one-hand operation involving three fundamental functions: grasping, sharp or blunt dissection, and dividing the tissues. With this single dissector, laparoscopic cholecystectomy can be rapidly and safely performed without changing the forceps or instruments through the trocar.
BACKGROUND/PURPOSE In living-donor liver transplantation (LDLT), hepatic arterial thrombosis and portal venous thrombosis are critical problems that can result in graft loss. Only intraoperative Doppler ultrasound (IDUS) is able to evaluate blood flow in the reconstructed vessels. The aim of this study was to evaluate the utility of a newly developed… (More)
BACKGROUND/AIMS The clinical usefulness of alpha-fetoprotein (AFP) in the management of hepatocellular carcinoma (HCC) remains controversial. This study aimed to assess the prognostic reliability of serum AFP levels per tumor volume (AFP/volume) after curative resection. METHODOLOGY A total of 196 patients with HCC were analyzed with reference to serum… (More)
UNLABELLED The response rate to sorafenib in hepatocellular carcinoma (HCC) is relatively low (0.7%-3%), however, rapid and drastic tumor regression is occasionally observed. The molecular backgrounds and clinico-pathological features of these responders remain largely unclear. We analyzed the clinical and molecular backgrounds of 13 responders to sorafenib… (More)
