WELCOME! You have just entered the Changhai AL prediction website: a project originally endorsed by Colorectal Surgery of Changhai Hospital in order to give evidence to predict anastomotic leakage (AL) of patients with rectal cancer (RC) undergoing anterior resection (AR).
AL is one of the most common and serious complications after AR for rectal cancer. The incidence of AL varies from 3% to 21% according to previous reports. Patients with AL are likely to suffer from increased length of hospital stay and rates of re-operation, and even recurrence and mortality. Some of the patients may even require a de-functioning stoma that would significantly affect their quality of life. A temporary stoma is often recommended for patients with high risk of AL. Our random forest classifier is an innovative and practical model to effectively predict AL, and could provide rational advice on whether to perform a temporary stoma, which might reduce the rate of stoma and avoid the ensuing complications.
INSTRUCTIONSScrolling down on the website, the Calculator including 8 questions gives you a prediction of AL based on the pre-operative and intra-operative assessment. The “calculate” button will then generate result. The “YES” or “NO” result can help you decide whether to do a temporary stoma during the surgery. The prediction of AL can be saved in your electronic storage in order to be shared, viewed, and printed.
*Surgical approach includes open surgery, laparoscopic surgery (Lapa) and laparoscopic surgery by surgeons within first year of laparoscopic surgery (Lapa1stY).
#Surgeon volume is divided into high volume surgeon (amount of colorectal surgeries ＞100 during that year) and low volume surgeon (≤100 ).
