Introduction

Colorectal section of Cleveland Clinic

Laparoscopic conversion rates are dependent on a multitude of factors which require appropriate adjustment for patient, intra-operative and surgeon-related factors.The Cleveland Clinic Colorectal Laparoscopic Conversion (CCF-CLC) model is a simple additive score that can be used in everyday practice to predict outcomes in patients undergoing laparoscopic colonic and rectal surgery. The work was presented at the SAGES Scientific meeting in Denver, Colorado, March 31st to April 3rd, 2004.

There is also a wealth of general information on risk prediction in surgery - this area of the site is constantly being updated and it is worth checking back on a regular basis. The service described above is provided free of charge with no liability attached (see disclaimer).

Calculate the Cleveland Clinic Colorectal Laparoscopic Conversion Score

Choose a value in each category that matches your patient from the drop down list. Default values (the lowest score) are shown for each category. Simply submitting the form as it is without changing the values still privides a risk for conversion to open surgery based on a patient undergoing small bowel resection without any risk factors or intra-operative adverse findings by a surgeon with an operative experience of less than 25 colorectal cases.

Study investigators: Dr Anthony Senagore, Dr Conor Delaney, Dr Victor Fazio, Dr Paris Tekkis
