Background:

Resections for elderly colorectal cancer (CRC) are forecasted to grow, particularly in those beyond the age limit of screening (> 80 years). However, literature on operative outcomes after CRC procedures in the oldest old is focused primarily on operative mortality. We hypothesize that older age will additionally impact operative morbidity after CRC resections in a multihospital, risk-adjusted database.

Study Design:

We identified 19,375 patients> 40 years who underwent CRC procedures in the 2005 to 2008 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Pre-, intra-, and postoperative factors were compared by age groups. Multivariable techniques were used to assess the effects of older age on operative outcome measures, adjusting for covariates.

Results:

Over 20% of our cohort was older than 80 years. Of those, 17% developed major …
