Conservative Management of Gallstone Disease in the Elderly Population: Outcomes and Recurrence.

Background & Aims: The prevalence of gallstone disease increases with age, being early cholecystectomy the most accepted treatment in the vast majority of patients in order to prevent complications and recurrence. The aim of this study is to determine the recurrence rate and its possible predictors after initial non-operative management.

Materials And Methods: We reviewed a consecutive series of patients, older than 65 years, admitted for a gallstone-related disease and treated with a non-operative management between January 2010 and December 2013.

Results of the Spanish national nosocomial infection surveillance network (VICONOS) for surgery patients from January 1997 through December 2003.

Background: In 1997, a national standardized surveillance system for nosocomial infections (NI) in surgery patients was established in Spain. This system, known as the VICONOS program, is based on the US National Nosocomial Infection Surveillance System (NNISS). Herein, we present a summary of the data collected from January 1997 to December 2003.

Standardized infection ratios for three general surgery procedures: a comparison between Spanish hospitals and U.S. centers participating in the National Nosocomial Infections Surveillance System.

Objectives: To compare Spanish surgical wound infection (SWI) rates for three procedures with those published by the U.S. NNIS System, and to analyze quarterly trends.

Nosocomial infection in surgery wards: a controlled study of increased duration of hospital stays and direct cost of hospitalization.

Excess length of hospital stays and associated costs were assessed in patients hospitalized in the department of general and digestive surgery who acquired nosocomial infections. A prospective study of matched infected-uninfected patients nested in a cohort was used to estimate the length of the hospital stay of infected patients. Matched controls were obtained with respect to patient exact primary diagnosis, operative procedure and classification, age and, if possible, underlying disease, elective or emergency procedure and invasive devices.
