[Giant primary retroperitoneal teratoma--case report and review of the literature].

Teratomas are germ cell tumors of a nonseminomatous type. Their incidence is characterized with a bimodal curve, but basically they are a pathology of the small age. Primary localization in the retroperitoneal space is seen in over 40% of cases with teratoma Preoperative differentiation from other bulky pathologic processes in this region presents a challenge to the surgeon.

[Clamping procedures in hepatic surgery].

The advance of liver surgery and transplantation offers a new procedures--vascular clamping. Results of hepatic resections depends essentially on proper control of intraoperative hemorrhage. We present here the different procedures for vascular clamping and discussing their indications.

[Prognostic factors for survival in primary liver cancer].

Background: The aim of this study was to identify the prognostic factors of survival after curative resection of primary liver cancer (PLC).

Study Design: Thirty four patients underwent resection PLC between January 1991 and December 2000. Univariate and multivariable analysis were used to retrospectively identify factors associated with overall survival when resection was curative for primary tumor.

[Large primary liver cancer (> 10 cm)- diagnosis and surgical treatment].

Background: Primary liver cancer (PLC) over 10 cm. in diameter at the time of diagnosis continues to account for a number of patients undergoing hepatic resection. This study evaluated the clinicopathological features and outcome following surgery for large PLC.
