Development and Validation of a Mobile Application for Predicting the Risk of Anastomotic Leakage in Patients Operated for the Treatment of Colorectal Cancer

Background: The scientific literature presents some tools for predicting the risk of anastomotic leakage in patients operated on for the treatment of colorectal cancer. However, a mobile application for this purpose has not been built yet.

Aim: To build and validate a mobile application capable of predicting the risk of anastomotic leakage in patients operated for the treatment of colorectal cancer.

Methods: An application containing a prognostic index for urgent colectomy and an index for elective colectomy was built (Leak Index). This application was validated by judges in the area of ​​general surgery and coloproctology using the SUS table (Scale Usability System).

Results: Regarding the general evaluation, it is observed that the judges agree regarding the usability of the application, with a general S-CVI of 0.90 being registered, above the criterion of 0.80, which corresponds to 90.01% of general agreement of the evaluators. Raters mostly agree on ease of use (I-CVI = 0.95) and that people will quickly learn to use it (I-CVI = 0.955).

Conclusion: An application with excellent usability rates was built to predict the risk of anastomotic leakage in patients who underwent colectomy for the treatment of colorectal cancer.
