BACKGROUND/AIMS We performed a randomized trial to evaluate whether fixation of the greater omentum to the peritoneum prevents delayed gastric emptying and other complications after left-sided hepatectomy. METHODOLOGY Patients undergoing left lateral segmentectomy or left hepatectomy were randomly assigned to a fixation group (n=24) and a non-fixation(More)
BACKGROUND/PURPOSE Delayed gastric emptying (DGE) sometimes occurs after left hepatectomy with lymphadenectomy. We performed fixation of the greater omentum to the peritoneum to prevent DGE and other complications in patients undergoing left hepatectomy with lymphadenectomy for cholangiocarcinoma. METHODS Patients undergoing left hepatectomy with(More)
This study assessed the safety and utility of preoperative splenic artery embolization before laparoscopic splenectomy in children. Five young girls with a mean age of 13.2 years underwent laparoscopic splenectomies at the authors’ institution from August 1998 to April 2003. Three of the patients had idiopathic thrombocytopenic purpura, and two had(More)
BACKGROUND The aim of the present study was to clarify the surgical outcome and long-term prognosis of laparoscopic liver resection (LLR) compared with conventional open liver resection (OLR) in patients with colorectal liver metastases (CRLM). METHODS A one-to-two propensity score matching (PSM) analysis was applied. Covariates (P < 0.2) used for PSM(More)
BACKGROUND Hepatocellular carcinoma (HCC) in persons with liver cirrhosis (LC) arises following hepatitis virus infection. Alcohol may accelerate the risk of development of LC and HCC. Cytochrome p450 2E1 (CYP2E1) oxidizes ethanol to form acetaldehyde and aldehyde dehydrogenase 2 (ALDH2) detoxifies acetaldehyde, which is carcinogenic in humans, and both(More)
The incidence of hepatocellular carcinoma (HCC) is rising worldwide. Spontaneous rupture of HCC occasionally occurs, and ruptured HCC with intraperitoneal hemorrhage is potentially life-threatening. The most common symptom of ruptured HCC is acute abdominal pain. The tumor size in ruptured HCC is significantly greater than that in non-ruptured HCC, and HCC(More)
We describe the spontaneous rupture of a simple hepatic cyst associated with a benign course. A 64-year-old woman was admitted for right upper quadrant pain. The patient denied a history of abdominal trauma. Abdominal computed tomography (CT) showed a huge solitary hepatic cyst (diameter, 10 cm) in the right lobe. Part of the cyst surface was irregular, and(More)
BACKGROUND/AIMS Partial splenic embolization was developed as a non-surgical treatment for hypersplenism, but recently splenic embolization has been reported to improve the hepatic function. We undertook long-term evaluation of partial splenic embolization in patients with hepatic cirrhosis in comparison with patients not undergoing embolization. (More)
OBJECTIVES To present long-term results of angiographic partial splenic artery embolization (PSE) as a supplemental treatment of portal-systemic encephalopathy. METHODS Twenty-five patients with portal-systemic encephalopathy were divided into two groups: 14 patients underwent transportal obliteration and/or balloon-occluded retrograde transvenous(More)
Partial splenic embolization (PSE) is a non-surgical procedure developed to treat hypersplenism as a result of hepatic disease and thus avoid the disadvantages of splenectomy. A femoral artery approach is used for selective catheterization of the splenic artery. Generally, the catheter tip is placed as distally as possible in an intrasplenic artery. After(More)
