Why was this calculator made?
This calculator was designed to aid pre-operative patients counselling and surgeon decision making, with the aim of providing individualized patient care.
Who can this calculator be used for?
This calculator is applicable to adult patients with colon cancer (distal edge located at more than 15 cm from the anal verge, measured by rigid proctoscopy) treated with elective or emergent surgery, with local curative intention, in whom primary anastomosis with no protective stoma is performed.* We encourage validation of this calculator on your population (perhaps a historical cohort) prior to use.
How was this calculator made?
This calculator is based on the nomogram published by Frasson et al. based on data from a large Spanish cohort of patients.* The modified calculator was then prospectively validated and shown to be more predictive than the surgeon's estimate of leak risk.** It is currently undergoing further external validation on a larger retrospective data-set.
