This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

The objective of this review is to compare colorectal resections with or without omentoplasty as intervention.

As primary outcome we will assess the rate of radiologically or clinically proven anastomotic leakages. (radiologically (contrast enema around day 10) or clinically proven (fecal drainage, clinical infection signs and contrast enema, re‐operation)).

Data on perioperative morbidity and mortality, especially omentoplasty‐related complications will be assessed as secondary outcomes.
