Incidence and risk factors of venous thromboembolism in colorectal surgery: does laparoscopy impart an advantage?

Brian Buchberg et al. Arch Surg. 2011 Jun.

Abstract

Objectives: Laparoscopy is increasingly used in colon and rectal procedures. However, little is known regarding the incidence of venous thromboembolism (VTE) in laparoscopic colorectal (LC) compared with that in open colorectal (OC) procedures. We aimed to compare the incidences and to highlight the risk factors of developing VTE after LC and OC surgery.

Design: Analysis of the Nationwide Inpatient Sample data from 2002 through 2006.

Setting: National database.

Patients: Patients who underwent elective LC and OC surgery from 2002 through 2006.

Main outcomes measure: Incidence of VTE during initial hospitalization after LC and OC surgery; VTE classified by surgical site, pathology type, and at-risk patient population.

Results: Over a 60-month period, 149,304 patients underwent LC or OC resection. Overall, the incidence of VTE was significantly higher in OC cases (2036 of 141,456 [1.44%]) compared with the incidence in LC cases (65 of 7848 [0.83%]) (P < .001). When stratified according to pathologic condition and surgical site, the overall rate of VTE was highest in patients with inflammatory bowel disease and in those undergoing rectal resections. Patients who underwent OC surgery were almost twice as likely to develop VTE compared with patients who underwent LC surgery. We also identified malignancy, obesity, and congestive heart failure as statistically significant (P < .05) risk factors for VTE in OC and LC surgery.

Conclusions: On the basis of data from a large clinical data set, the incidence of perioperative VTE is lower after LC than after OC surgery. These findings may help colorectal surgeons use appropriate VTE prophylaxis for patients undergoing colorectal procedures.
