In a population-based analysis relying on 149 304 patients who underwent either a laparoscopic colorectal resection or an open colorectal resection, Buchberg et al1 showed that patients who underwent an open colorectal resection were nearly twice as likely to develop venous thromboembolism following surgery than patients who underwent a laparoscopic colorectal resection (odds ratio, 1.8 [95% CI, 1.4-2.2]). However, they failed to adjust for important patient, hospital, and clinical confounders.
