Background
The occurrence of venous thromboembolism (VTE), manifesting as deep vein thrombosis or pulmonary embolism, after gastric and colorectal cancer surgery remains poorly characterized. The purpose of this study was to investigate the incidence of VTE following laparoscopic surgery in Japanese patients with gastric and colorectal cancer and identify the associated risk factors.
Methods
We prospectively analyzed VTE events after laparoscopic surgery for gastric and colorectal cancer from April 2012 to March 2013 in our institute. Deep vein thrombosis was diagnosed with Doppler ultrasound sonography of the lower limb. Thromboprophylaxis, graduated compression stockings, and intermittent pneumatic compression were used in all patients. Fondaparinux sodium was used in several patients. We examined all patients’ plasma D-dimer levels throughout the perioperative period.
Results
In total, 101 patients were enrolled in this study; 71 who underwent laparoscopic surgery for gastrointestinal cancer were finally analyzed. Thirteen patients (18.3 %) developed asymptomatic VTE. There were no relationships between the development of VTE and perioperative factors such as cardiovascular disease, operation time, blood loss, postoperative complications, and fondaparinux administration. Neoadjuvant treatment (chemotherapy or chemoradiotherapy) was significantly associated with VTE (p < 0.05). Plasma D-dimer levels were higher 7 days after surgery in patients with than without VTE, although the levels remained high after surgery in all patients.
Conclusions
The incidence of VTE among Japanese patients who underwent laparoscopic surgery for gastrointestinal cancer was not low. In particular, clinicians should consider the higher risk of VTE in patients undergoing neoadjuvant therapy.
