Silymarin (SIL), a standardized plant extract containing about 60% polyphenole silibinin, is used as a hepatoprotective agent. Its antifibrotic potential in chronic liver diseases has not been explored. Therefore, we applied SIL to adult Wistar rats that were subjected to complete bile duct occlusion (BDO) by injection of sodium amidotrizoate (Ethibloc).(More)
INTRODUCTION Incidental detection of a carcinoid tumor of the appendix after appendectomy is often accompanied by uncertainty about the further procedure. The tumor frequency in our own patient population, the further course in these children and a practicable follow-up protocol have to be determined. PATIENTS AND METHODS All appendectomies performed(More)
Between 1978 and 1991 a total of 136 operations with the laparoscope have been performed. 79 additional laparoscopies were carried out for diagnostic purposes. The most frequent indications for operative laparoscopy were: adhesions, abdominal cysts, tumors, gonadectomy, appendectomy and cholecystectomy. Diagnostic laparoscopies were performed for the(More)
BACKGROUND AND OBJECTIVE Interstitial laser therapy (ILT) is a minimally invasive treatment method for congenital vascular malformations (CVM). This study was intended to show whether or not open magnetic resonance imaging (MRI) offers a means of on-line thermometry and procedure control. STUDY DESIGN/PATIENTS AND METHODS ILT using a bare fiber and an(More)
During the last few years the laser has become a very interesting instrument in pediatric surgery. This is the result of the wide variation in tissue interactions and the possibility of specific applications. The CO2 laser is a highly precise cutting instrument whereas the argon laser has its great advantage in the treatment of superficial vascular(More)
We report on 4 children where Meckel's diverticula (MD) were excised laparoscopically. In two of the children the finding of an MD was incidental and in two it was suspected preoperatively. In three of the patients the MD was ligated by means of an "endoloop" and could be removed in a similar manner to an appendix. In one patient the MD was resected by(More)
PURPOSE To investigate the use of magnetic resonance (MR) imaging to guide interstitial laser therapy of deep hemangiomas and vascular malformations in children. MATERIALS AND METHODS Sixteen children aged 3 months to 16 years with symptomatic vascular lesions underwent percutaneous laser treatment. MR imaging guidance of the laser applicator and online(More)
Duodenal gastrinomas in childhood are extremely rare and often missed at first medical consultation. We report on a 7-year-old child with sporadic gastrinoma of primary localisation in the distal duodenum. Small metastases in the liver and regional nodes were detected pre-operatively by somatostatin receptor scintigraphy (SRS) but not by other conventional(More)
BACKGROUND Classification systems for necrotizing enterocolitis (NEC) in preterm infants have been developed to define severity grades relevant for treatment and prognosis. Multisystem organ failure (MSOF) and capillary leak syndrome (CLS) also have prognostic value in these patients. The aim of this retrospective study was to investigate the incidence and(More)
