    ABSTRACT: Determination of the functional hepatic reserve is still controversial. Many tests have been proposed, but the assay based on formation of the lidocaine metabolite, monoethylglycine xylidide, seems to offer a promising approach to this problem. In this study we evaluated the effectiveness of the monoethylglycine xylidide test in the clinical evaluation of 31 cirrhotic patients submitted to three different therapeutic options (sclerotherapy, transjugular intrahepatic protosystemic shunt and surgical procedures) and in 1 patient submitted to right hepatectomy for giant hepatic angioma. We found a statistically significant difference between Child A and C patients and between Child B and C patients. The test did not differentiate Child A from Child B patients. We found no correlation between the Child-Pugh score, serum bilirubin, albumin and prothrombin time. There were no differences among the three groups of patients that could be statistically related to their therapy. The monoethylglycine xylidide test seems to be an attractive alternative to previous methods for the evaluation of the functional hepatic reserve, but further studies are necessary to assess the prognostic value of the test in cirrhotics, to separate the independent contribution of portosystemic shunting and hepatocyte dysfunction to monoethylglycine xylidide formation, and to evaluate the test as a prognostic index in cirrhotic patients submitted to general surgery.

    ABSTRACT: Duodenal diverticulum is not a rare disease, with a frequency of 1-3% in radiologic review and of 2.8-20% in pathology review; The spontaneous perforation of a perivaterian duodenal diverticulum is a rare complication, with about 100 cases reported in the literature. The post-traumatic perforation of a perivaterian diverticulum is an exceptional event, reported in single cases of the oriental literature. The authors report their personal experience about two cases of diverticular duodenal perforation, one spontaneous, the other post-traumatic, discussing the surgical problems that this rare complication present.

    ABSTRACT: Castelman disease (CD) is a rare lymphadenopathy that usually presents as a solitary, slow growing mass; its etiology is still unknown. The authors described a case of CD localized in the retro-pancreatic space. A 33-year old patient, female, underwent abdominal ultrasonography because of upper right abdominal pain. The ultrasound showed gallbladder stones and a mass of 4 cm in diameter behind the pancreatic head, modifying the shape of the inferior vena cava. The patient underwent surgical excision and histological examination showed a hyaline type of CD. In the 70% of the cases, the disease is located in the mediastinum, only in 14% of the cases in the retroperitoneal space. The case we report is a hyaline type of CD that is the most frequent histological type, constitutes 90% of the cases, occurs usually in the young population and after surgical excision has a very good prognosis. Different is the clinical behaviour of the plasma cell type of CD that has an aggressive and often fatal clinical outcome. The patient we treated is still free of any symptoms one year after the operation.
