Incidencia de falla anastomótica en intestino delgado, colon y recto, Bogotá, Colombia

Abstract

ntroduction: Anastomotic leak is one of the main complications of patients submitted to gastrointestinal surgery. It occurs in approximately in 3.4% to 15% of cases. In Colombia the overall incidence of anastomotic leak is not known. Material and methods: A prospective cohort study that included patients undergoing anastamosis and who were followed up for up to 30 days. A descriptive analysis of the information was performed. The variables were analyzed with the chi-square test and the Kaplan-Meller graphs were used to determine the time to the event. Data analyses was performed on STATA 13. Results: 195 patients were admitted. 47.1% were male, and the median age of the study group was 60 years (ICR: 48-70). The incidence of anastomotic failure was 10.8% and the incidence rate was 10.2 per 1000 person-years; 29.7% of the patients presented postoperative complications and a mortality rate of 9.7%. The median hospital stay was 8 days (ICR: 5 - 16). Conclusion: The incidence of anastomotic leak observed appears in accordance with reports published in the world literature. The history of abdominal surgery as well as emergency surgery were the most frequent factors among the patients who developed anastomosis leak.
