We measured the distance 112 patients walked in 6 min, as well as their peak oxygen consumption pedalling a bicycle, week before scheduled resection of benign or malignant colorectal disease. The distance walked correlated with peak oxygen consumption, the former 'accounting' for about half the variation in the latter, r² 0.52 (95% CI 0.38-0.64), p < 0.0001. In the first postoperative month, 42/112 patients experienced a complication. In multivariate analysis, complications were less likely with longer walking distances and increasing age: the odds ratio (95% CI) reduced to 0.995 (0.990-0.999) for each metre distance, and to 0.96 (0.93-0.99) with each year of age, p = 0.025 and p = 0.018, respectively. The distance walked in 6 min before surgery can provide prognostic information when cardiopulmonary exercise testing is unavailable.
