Caloric intake capacity as measured by a standard nutrient drink test helps to predict weight loss after bariatric surgery.

Background: Instruments that enable to select individuals that will benefit most from bariatric surgery (BS) are necessary to increase its cost-efficiency. Our goal was to assess if intake capacity, measured with a standardized test, predicts response to BS.

Methods: Patients with criteria for BS were randomly allocated to laparoscopic gastric bypass (LRYGB) or sleeve gastrectomy (LSG).

Colorectal cancer survival: results from a hospital-based cancer registry.

Introduction: colorectal cancer is one of the most common malignancies in developed countries. Data on specific and 10-year survival are scarce. This study analyzes overall and disease-specific survival for patients with colorectal cancer and assesses the value of clinical factors on disease-specific survival.

[Esophageal adenoma-carcinoma and Barrett's esophagus. Gastric adenocarcinoma and Helicobacter pylori].

In the last two decades, the incidence of esophageal cancer has progressively increased, especially that of adenocarcinomas localized in the esophagogastric junction. The incidence of gastric cancer has decreased in the last few decades, although this decrease shows wide geographical variations. Thus, the prevalence of gastric cancer continues to be high in countries such as Chile, Colombia and Ireland and this disease remains the most frequent neoplasm in both sexes in China and Japan.
