Study
Aprotinin versus control
Lentschener 1999	In this trial, survival was reported for patients undergoing liver resection for colorectal liver metastases. The exact number of patients in each group was not stated and survival outcomes could not be included for meta‐analysis. The one‐year survival in patients with colorectal liver metastases was statistically greater in the aprotinin group than the control group. However, the survival advantage was lost at 28 months.
