Survey of the use of thromboprophylaxis in laparoscopic surgery in Denmark

Background: The aim of this study was to determine the current use of thromboprophylaxis for laparoscopic surgery in Denmark. Methods: Postal questionnaires were sent to all Danish surgical departments that performed laparoscopic surgery according to the National Laparoscopic Cholecystectomy Database. Results: There was a written protocol for thromboprophylaxis in 93 per cent of the responding departments. In 37 per cent thromboprophylaxis was used for all patients undergoing laparoscopic surgery; only 7 per cent used thromboprophylaxis sporadically. All departments used low molecular weight heparin, 74 per cent in combination with graduated compression stockings. The criteria for using thromboprophylaxis varied greatly; in many departments conversion of the procedure to an open operation was not considered a criterion. Some 20 per cent of the departments reported previous thromboembolic complications following laparoscopic surgery. Conclusion: Despite the widespread use of thromboprophylaxis, symptomatic thromboembolic complications were reported from several departments. Further studies are needed to determine whether laparoscopic surgery should be considered a high‐risk procedure. © 2001 British Journal of Surgery Society Ltd
