    Abstract:
    AIM: The study investigated the rate of significant venous thromboembolism (VTE) following colorectal resection during the index admission and over 1 year following discharge. It identifies risk factors associated with VTE and considers the length of VTE prophylaxis required. METHOD: All adult patients who underwent colorectal resections in England between April 2007 and March 2008 were identified using Hospital Episode Statistics data. They were studied during the index admission and followed for a year to identify any patients who were readmitted as an emergency with a diagnosis of deep venous thrombosis or pulmonary embolism. RESULTS: In all, 35 997 patients underwent colorectal resection during the period of study. The VTE rate was 2.3%. Two hundred and one (0.56%) patients developed VTE during the index admission and 571 (1.72%) were readmitted with VTE. Following discharge from the index admission, the risk of VTE in patients with cancer remained elevated for 6 months compared with 2 months in patients with benign disease. Age, postoperative stay, cancer, emergency admission and emergency surgery for patients with inflammatory bowel disease (IBD) were all independent risk factors associated with an increased risk of VTE. Patients with ischaemic heart disease and those having elective minimal access surgery appear to have lower levels of VTE. CONCLUSION: This study adds to the benefits of minimal access surgery and demonstrates an additional risk to patients undergoing emergency surgery for IBD. The majority of VTE cases occur following discharge from the index admission. Therefore, surgery for cancer, emergency surgery for IBD and those with an extended hospital stay may benefit from extended VTE prophylaxis. This study demonstrates that a stratified approach may be required to reduce the incidence of VTE.
