[Gammagraphy with HMPAO-99mTc leukocytes in intestinal inflammatory disease].

The value of 99mTc-hexamethylpropyleneamine oxime (HMPAO) leukocyte images has been confirmed in patients with Inflammatory Bowel Disease. We performed 121 scintigraphic examination. The results were evaluated by radiologic and/or endoscopic examinations.

[Hydrogen peroxide-induced lesions in the digestive tract. Apropos 4 cases].

Gastrointestinal injury caused by caustic products a are relatively infrequent, occurring mainly in the upper gastrointestinal tract. Accidental ingestion accounts for most of the cases, and the severity and extent of damage produced, depends on the composition and volume of the caustic agent ingested; endoscopy is a safe and effective diagnostic procedure. We report four unusual cases of caustic injury of the gastrointestinal tract due to hydrogen peroxide, two cases due to oral ingestion and another two due to the accidental administration of enemas, there was a good clinic and endoscopic recovery with conservative treatment.

[Chemoembolization and posterior liver transplantation as therapeutic strategy for hepatocarcinoma].

Orthotopic Liver Transplantation (OLT) is the only surgical approach to non-resectable hepatocellular carcinoma (HCC) but, so far its results has been poor. During 41 months 112 patients underwent 123 OLT, nine of them had HCC over cirrhosis with a mean age 60 years. The etiology of cirrhosis was: alcohol in 1 and viral hepatitis in 8.
