"Textbook outcome(s)" in colorectal surgery: a systematic review and meta-analysis.

TO is achieved, on average in 55% of reported cases and it may predict short and long term post operative patient outcomes. This study did not detect a difference in rates between elective versus mixed case load TO proportions. There is no standardised definition in use of TO. Standardisation of the composite is likely required to enable meaning comparison using TO in the future and a Delphi consensus is warranted.
