Avances en tumores del estroma gastrointestinal: ¿hacia dónde vamos?

Gastrointestinal Stromal Sarcomas (GIST) are mesenchymal neoplasms whose incidence accounts for 1-2% of digestive tumors, being located in the stomach (55-60%) and small intestine (30%). The advances in its knowledge and management succeeded in the last years have being spectacular. This review aims to summarize the most important of them for surgeons.

Pyogenic granuloma of the large intestine: case report and review of reported cases in the adult.

Pyogenic granuloma (PG) is a polypoid lobular capillary hemangioma rarely described in the large bowel. We describe the case of a 72-year-old man with recent weight loss, anemia, and change in bowel habit. A 3cm×2cm polypoid lesion in the right flexure of the colon was observed and treated with extended right hemicolectomy.

Radiological and pathological assessment of hepatocellular carcinoma response to radiofrequency. A study on removed liver after transplantation.

Background: The real efficacy of radiofrequency ablation (RFA) in destroying hepatocellular carcinoma is not completely known, nor is the ability of computed tomography (CT) to precisely assess response. Our aims were to analyze pathological response, tumor size influence, and CT response evaluation.

Materials And Methods: This was a retrospective study of 30 hepatocellular carcinoma nodules treated by RFA before liver transplant (LT) in 28 patients.
