BACKGROUND Although intrahepatic arterioportal fistula (APF) due to acquired or congenital causes are infrequent, they are listed among the causes of portal hypertension. PURPOSE The aim of this study was to present the results of intrahepatic APF treatment with embolotherapy in six cases. MATERIAL AND METHODS Transarterial detachable balloon and coil(More)
PURPOSE Lymphocele following kidney transplantation is a well-known complication. We present here the long-term results of percutaneous drainage and ethanol sclerosis in posttransplant lymphoceles. PATIENTS AND METHODS Between October 1988 and September 2003, 18 patients with symptomatic lymphoceles were treated with percutaneous transcatheter ethanol(More)
It has been demonstrated that hyperbaric oxygen (HBO) is useful as an adjunctive therapy for Crohn's disease. However, its effects on ulcerative colitis have not been investigated. In the present study, HBO was tested for acetic acid-induced colitis, and antioxidant systems were evaluated to clarify its possible mode of action. Thirty-six Sprague-Dawley(More)
Combined chemotherapy and radiation therapy is the standard treatment for epidermoid carcinoma of the anal canal. Failures are often not associated with distant recurrence and are therefore potentially amenable to salvage abdominoperineal resection. The aim of this study was to review our experience with abdominoperineal resection following failure of(More)
During ischemia-reperfusion, free oxygen radicals which directly affect renal cells may cause delayed graft function. We investigated whether there was a difference regarding antioxidant enzyme content between use of Ringer's lactate (RL) versus University of Wisconsin (UW) perfusion solutions in kidney transplantation. Ischemia was achieved by clamping the(More)
BACKGROUND Oxidative stress is one of the leading causes of cardiovascular morbidity and mortality in chronic kidney disease. Although it is clear that many metabolic abnormalities improve, the effects of kidney transplantation on oxidative state are obscure. METHODS Twenty-three kidney transplant patients were included in the study. Eleven patients (mean(More)
OBJECTIVE Pilonidal sinus (PS) is a chronic intermittent disease. There are numerous surgical treatment procedures that have been previously reported, yet none have been proved to be ideal. The main issues concerning the surgical treatment of PS are simplicity and cost-effectiveness. This study is designed to research the possibility of decreasing operation(More)
The effect of ischemia-reperfusion (I/R) injury within a transplanted kidney has not been reported on the liver as a remote organ. One hypothesis is that there is no difference between kidney perfusion solutions regarding antioxidants in liver after an I/R injury. We used four pigs with Ringer's lactate (RL); four with university of Wisconsin (UW); and two(More)
OBJECTIVE Colon cancer patients presented with obstruction were known to have worse postoperative morbidity and mortality rates, but conflicting data has been reported in recent years. We aimed to investigate postoperative complication rates, and short and long-term oncological outcomes in patients with colon cancer treated with either emergency surgery due(More)
Multiple endocrine neoplasia type 2B (MEN 2B) is a rare syndrome characterized by medullary thyroid carcinoma (MTC), pheochromocytoma and typical phenotypic features, such as marfanoid habitus, multiple mucosal ganglioneuromas and thickened corneal nerves. Individuals with MEN 2B may develop megacolon and pseudo-obstruction due to intestinal(More)
