    (2005) Boza, C; Riquelme, A; Ibañez, L; Duarte, I; Norero, E; Viviani, P; Soza, A; Fernandez, JI; Raddatz, A; Guzman, S; Arrese, M
    Background: Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are conditions gaining increasing recognition in hepatology as a potential cause of cirrhosis and end-stage liver disease. Obesity is one of the main risk factors. The aims of this study were to determine the frequency of NAFLD in obese patients and to identify variables that predict NASH.

    Results of surgical treatment of gastric cancer
    (1999) Llanos, O; Guzman, S; Pimentel, F; Ibañez, L; Duarte, I
    Background/Aim: The extent of gastric resection and the role of lymphadenectomy in the treatment of gastric cancer are controversial. Methods: This study evaluates the results of radical gastric resection (D2 lymphadenectomy) in 375 patients with a gastric carcinoma operated according to a prospective protocol, Results: Total gastrectomy was performed in 196 and a subtotal gastrectomy in 179 patients, with an operative mortality of 3.5 and 2.8%. The presence of lymph node metastasis was related to the depth of the tumor in the gastric wall. The cumulative 5-year survival was dependent on the depth of tumoral invasion in the gastric wall and also on the presence of lymphatic metastasis. Curative resection had a significantly better 5-year survival (72%) than noncurative resection (26%). Conclusion: Although it is difficult to prove the benefits of extended lymphadenectomy in the surgical treatment of gastric carcinoma, the results of these series seem to support its usefulness.
