Predicting the risk of colorectal anastomotic leak based on preoperative mapping of the blood supply of the bowel

ArXi:2606.02156v1 Announce Type: cross Anastomotic leak remains one of the most serious complications following colorectal cancer surgery, substantially affecting patient outcomes, recovery trajectories, and healthcare costs. Despite advances in imaging technology, current preoperative assessment relies only on clinical assessment, a process that is subjective, error-prone, and highly dependent on individual expertise. To date, no validated CT-based method exists to predict anastomotic leak risk prior to surgery.
