AbstractCommonly performed elective surgical procedures on the alimentary tract are carried out with low morbidity and low mortality in most hospitals in the United States. There are some procedures on the alimentary tract that are performed with a relatively low frequency and are associated with higher mortality. Volume is a surrogate marker associated with improved outcome, with relative differences being dependent on the complexity of the procedure and the frequency with which it is done. Both surgeon and institutional volume matters, but it seems that improved operative mortality can be reached with lower surgeon volume in high-volume institutions. It appears that volume can be substituted in part for by specialization and training, with improved outcomes based on specialist credentials and fellowship training.
