Purpose Anastomotic leakage is associated with increased morbidity and mortality. However, there is no accurate tool to predict its occurrence. We evaluated the predictive value of visible light spectroscopy (VLS), a novel method to measure tissue oxygenation [saturated O 2 (StO 2 )], for anastomotic leakage of the colon and the rectum. Method Oxygen saturation in the bowel was measured in 77 colorectal resections. The anastomosis was between 2 and 30 cm (mean 13 cm) from the anal verge. The oxygen saturation was measured in the colon and rectum before and after anastomosis construction. This was compared with a reference measurement in the caecum. Data on postoperative complications were prospectively collected. Results Anastomotic leakage occurred in 14 (18%) patients. When compared with a leaking anastomosis, normal anastomoses showed rising O 2 values during the operation (mean StO 2 72.1 ± 9.0–76.7 ± 8.0 vs 73.9 ± 7.9–73.1 ± 7.4) ( P ≤ 0.05). There were also higher StO 2 values in the caecum compared with those which ultimately leaked (73.6 ± 5.7 normal anastomoses , 69.6 ± 5.6 anastomotic leaks) ( P ≤ 0.05). Both StO 2 values were predictive of anastomotic leakage. Conclusion Tissue oxygenation O 2 appears to be a potentially useful means of predicting anastomotic leakage after colorectal anastomosis.
