OVA-LEAK: Prognostic score for colo-rectal anastomotic leakage in patients undergoing ovarian cancer surgery
One of the more devastating consequences of surgery for ovarian cancer is post-operative leakage of bowel content from an anastomotic site. This complication has a mortality of about 3%.
A strategy for avoiding this complication of difficult surgery is to perform a bowel diversion in the form of an ileostomy as part of the initial surgery. It is however difficult to predict which patients will be liable to post-operative leak. An application; OVA-LEAK, accessible via the web has been developed to predict which patients should be managed in this way*.
This study looked at the value of the OVA-LEAK score with a comparison to the standard clinical assessment of those patients requiring bowel diversion during initial surgery. The OVA-LEAK score had a negative predictive value of 97% meaning it is likely that those women who score well will not have a leak. For those women who qualified for bowel diversion it was almost four times more likely to be beneficial than for those women who were chosen by clinical assessment only.
