PURPOSE To assess with volumetric computed tomography (CT) the pattern and extent of hepatic regeneration induced with transarterial embolization of initially unresectable hilar cholangiocarcinoma (Klatskin tumor). MATERIALS AND METHODS In this prospective study, 13 patients (four men, nine women) with hilar cholangiocarcinoma, aged 43-74 years (mean +/-(More)
OBJECTIVE The authors evaluated the complication rate and outcome of side-to-side common bile duct anastomosis after human orthotopic liver transplantation. SUMMARY BACKGROUND DATA Early and late biliary tract complications after orthotopic liver transplantation remain a serious problem, leading to increased morbidity and mortality. Commonly performed(More)
PURPOSE To assess AMI-25- versus gadolinium-enhanced magnetic resonance (MR) imaging in the differential diagnosis of liver tumors. MATERIALS AND METHODS Twenty-nine patients with liver tumors underwent unenhanced, AMI-25-enhanced (15 micromol/kg), and gadolinium-enhanced(0.1 mmol/kg) imaging within 2 weeks. RESULTS A significant (P< .05) difference in(More)
The Budd-Chiari syndrome (BCS) with hepatic vein occlusion is a rare disorder that can effectively be treated with orthotopic liver transplantation. In this retrospective analysis we report on 7 patients who received 9 liver grafts for terminal BCS. One patient died after 4 months due to cytomegalovirus-pneumonia. The actuarial survival rate is 85.7%(More)
Caroli's disease is characterized by uni- or bilobar cystic enlargement of the intrahepatic biliary tract. Clinical symptoms include recurrent cholangitis, right upper quadrant abdominal pain and jaundice. The diagnosis is usually established preoperatively based on abdominal ultrasound, computertomography and ERCP. Eight patients suffering from unilobar(More)
The pancreaticojejunostomy after duodenopancreatectomy is the "Achilles' heel" of the procedure. Herein we describe a technique for percutaneous drainage of the efferent limb of the Roux-en-Y loop relieving tension from the anastomosis. Seventy-six Whipple procedures, using this technique, have been done. The operative mortality rate was 1.3 per cent and(More)
Mycophenolate mofetil (MMF) has been used successfully as an immunosuppressive agent after kidney and heart transplantation, but experience with MMF after liver transplantation is still limited. Between August 1995 and January 1996, we treated 20 patients with MMF after orthotopic liver transplantation in an open, prospective study. Five out of eight(More)
BACKGROUND Conventional peritoneal dialysis fluids (PDF) have been shown to compromise the function of both leukocytes and human peritoneal mesothelial cells (HPMC). Various in vitro studies have identified the low initial pH in combination with high lactate content, as well as the hyperosmolality and high glucose concentration present in currently used(More)
