BACKGROUND Biliary cystadenomas and cystadenocarcinomas comprise 5% of cystic lesions in the liver. Cystadenomas are often incorrectly diagnosed as simple cysts, which results in inadequate therapy. Recurrence and possible malignant transformation are consequences of incomplete excision. Cystadenocarcinomas are very rare tumors that are felt to be(More)
The prevalence of angiographically proven coronary artery disease (CAD) in adults with end-stage liver disease who undergo evaluation for liver transplantation is unknown; also it is unclear if cholestatic liver disease represents an independent risk factor. Patients with end-stage liver disease over age 50 having liver transplantation were studied using(More)
Ischemic-type biliary stricture (ITBS) occurs in up to 50% after liver transplantation (LT) from donation after cardiac death (DCD) donors. Thrombus formation in the peribiliary microcirculation is a postulated mechanism. The aim was to describe our experience of tissue plasminogen activator (TPA) administration in DCD-LT. TPA was injected into the donor(More)
Although there are data in the literature about the safety and efficacy of laparoscopic liver resections, there are not many studies comparing laparoscopic versus open approaches in a case-matched design. The purpose of this study is to compare the perioperative outcome of laparoscopic versus open liver resections from a single institution. Thirty-one(More)
Data on 126 consecutive patients with periampullary tumors resected at the Cleveland Clinic between January 1950 and December 1984 were reviewed. One hundred five patients underwent pancreatoduodenal resection, 10 patients total pancreatectomy, and 11 patients local resection of the tumor. The site of tumor was ampulla of Vater (59), head of the pancreas(More)
This paper estimates the health costs at Superfund sites for conditions associated with volatile organic compounds (VOCs) in drinking water. Health conditions were identified from published literature and registry information as occurring at excess rates in VOC-exposed populations. These health conditions were: (1) some categories of birth defects, (2)(More)
Some chromosomal alterations can be associated with vascular abnormalities. For instance, Turner syndrome can be complicated by agenesis or hypoplasia of the portal venous system causing presinusoidal portal hypertension. Liver transplantation to treat this condition overcomes portal hypertension and reconstitutes the diminished hepatic function due to(More)
Thirty-three consecutive liver-transplant recipients were prospectively studied over a 37-mo period for evidence of cytomegalovirus infection. Sixteen (48%) episodes of cytomegalovirus infection were identified; 9 were primary infections and 7 were recurrent infections. Beginning with patient 8, gamma-globulin prophylaxis was routinely administered to most(More)
BACKGROUND The optimal treatment for incidental asymptomatic pancreatic cysts is not known. The purpose of this study was to determine whether nonmucinous cysts by cyst-aspiration analysis can be observed safely. METHODS A prospective protocol was initiated in September of 1999 for all suspected cystic neoplasms. Asymptomatic patients with negative cyst(More)
