[Renal tumors percutaneous ablation by microwave. Initial experience.].

Objective: To analyze retrospectively the safety and effectiveness of percutaneous microwave ablation of solid renal tumors, and also review different approach techniques.

Methods: It is a retrospective study approved by the ethics committee of both hospitals. 14 tumors with a mean size of 37 mm (12-50 mm) were treated in a single session, under general anesthesia and with CT guidance, in 14 patients (9 men) with a mean age of 66 years, using the ablation system AMICA by different approaches (trans pulmonary, trans peritoneal and retroperitoneal).

Arterial Calcium Stimulation with Hepatic Venous Sampling in the Localization Diagnosis of Endogenous Hyperinsulinism.

. The aim of this study was to assess the utility of arterial calcium stimulation with hepatic venous sampling (ASVS) in the localization diagnosis of endogenous hyperinsulinism. .

[Usefulness of arterial calcium stimulation with hepatic venous sampling in the localization diagnosis of endogenous hyperinsulinism].

Background And Objective: The aim of this study was to assess the utility of arterial calcium stimulation with hepatic venous sampling (ASVS) in the localization of tumors in patients with endogenous hyperinsulinism not detected with other methods.

Patients And Methods: We performed a retrospective study of 26 patients admitted to our hospital for hypoglycemia who underwent ASVS because the source of hyperinsulinism was not clearly identified by other imaging techniques. The histopathological result in patients who underwent a surgical procedure was considered the reference for statistical study of the accuracy of this technique.

Obstruction in patients with colorectal cancer increases morbidity and mortality in association with altered nutritional status.

Intestinal obstruction aggravates the prognosis of colorectal cancer (CRC) patients. The aim of this study was to carry out a comparative analysis of nutritional status and inflammatory response in CRC patients with or without intestinal obstruction. The study was carried out on 43 patients with CRC.
