Hepatocellular carcinoma with macrovascular invasion: multimodality imaging features for the diagnosis

2020

Hepatocellular carcinoma (HCC) is frequently associated with macrovascular invasion of the portal vein or hepatic veins in advanced stages. The accurate diagnosis of macrovascular invasion and the differentiation from bland non-tumoral thrombus has significant clinical and management implications, since it narrows the therapeutic options and it represents a mandatory con-traindication for liver resection or transplantation. The imaging diagnosis remains particularly challenging since the imaging features of HCC with macrovascular invasion may be subtle, espe-cially in lesions showing infiltrative appearance. However, each radiologic imaging modality may provide findings suggesting the prese…

Síndrome compartimental abdominal y síndrome de distrés intestinal agudo

2013

Seriously ill patients frequently present intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) as complications, and the associated mortality is very high. This review offers an update on the most controversial aspects of these entities: factors favoring their appearance, the most common causes, prognosis, and methods of measuring intra-abdominal pressure (IAP), physiopathological consequences in relation to the different organs and systems, and the currently accepted treatment measures (medical and/or surgical). Simultaneously to the strictly physical mechanisms of injury, such as direct compression of intra-abdominal organs and vessels, the transmission of IAP to ot…

31. Lokalisationsdiagnostik beim Hyperparathyreoidismus

1979

Im Hinblick auf die hohe chirurgische Erfolgsrate beim Auffinden pathologischer Epithelkorperchen ist eine invasive Lokalisationsdiagnostik mit Angiographie und selektiver Blutentnahme zur PTH-Bestimmung vor Erstoperationen nicht indiziert. Nichtinvasive Masnahmen wie Sonographie und Computertomographie lassen sich auch vor Erstoperationen einsetzen. Dabei eignet sich die Sonographie nur fur den Cervicalbereich, die Computertomographie im wesentlichen fur den vorderen Mediastinalbereich.

Caustic ingestion: CT findings of esophageal injuries and thoracic complications

2020

Ingestion of caustic substances, whether accidental or for the purpose of suicide, can cause severe lesions of the lips, oral cavity, pharynx, upper gastrointestinal system, and upper airways. In particular, caustic agents could be responsible for severe esophageal injuries resulting in short- and long-term complications. Because of these important clinical implications, timely diagnosis and appropriate management are crucial. In the evaluation of esophageal injuries, thoraco-abdominal computed tomography (CT) is preferable to endoscopy as it avoids the risk of esophageal perforation and allows the evaluation of esophageal injuries as well as of the surrounding tissue. In this review, we re…

Der Stellenwert der chirurgischen Behandlung des Neuroblastoms

1982

Results of surgical treatment of 29 neuroblastoma patients between 1968 and 1980 are presented. 13 of these children have remained free from relapses and complaints for more than 2 years. Despite the progress in (immuno)chemotherapy and (immuno)radiotherapy the prognosis depends on the kind of surgery performed, also and especially in stages III and IV (after Evans). Among the author's own patients it became evident that both the survival rate and the survival period were increased in the prognostically unfavourable cases by subtotal resection. No representative collective statistics are known and it will probably take quite some time before these can be compiled, since it is extremely diff…

Cholangitis prevention in endoscopic Klatskin tumor palliation: air cholangiography technique.

2009

INTRODUCTION: Endoscopic biliary drainage is the treatment of choice for inoperable hilar cholangiocarcinoma (so-called Klatskin tumor). Cholangitis is the main complication post-endoscopic retrograde cholangiopancreatography (ERCP) in Klatskin patients, specially when medium contrast is injected into biliary tree that could not be subsequently drained. Bacterial cholangitis is the principal cause of mortality in these patients. The aim of this study is to analyze cholangitis rate resulting from the use of air versus iodine contrast to obtain cholangiography during ERCP. METHODS: In 9 years, 188 inoperable Klatskin patients were recruited and divided into two groups: iodine (A) or air (B) c…
