Análisis de los factores predictivos de conversión en cirugía laparoscópica colorrectal

Abstract

Analysis of predictive factors for conversion to open surgery in laparoscopic colorectal surgeryBackground: Conversion to open surgery of laparoscopic procedures is not in essence a complication, but invalidates the benefi ts of laparoscopy. Aim: To identify the predictive factors for conversion in laparoscopic colorectal surgery. Material and Methods: Revision of medical records of all patients with colorectal disease operated using a laparoscopic approach, from 1998 to 2010. Gender, age, American Society of Anesthesiologists (ASA) score, body mass index (BMI), previous abdominal surgery, elective/urgency procedure, benign/malignant disease, type of resection and surgeon experience were recorded. A logistic regression model was done to determine which variables were predictive for conversion to open surgery. Results: The medical records of 582 patients aged 57 ± 17 years (45% men) were analyzed. The rate of conversion to open surgery was 7.1%. The logistic regression model selected as predictors of conversion a BMI over 25 kg/m
