Application prospect of minimally invasive surgical techniques in the treatment of biliary tract cancer

Due to the inherent disease characteristics and surgical difficulties, the develop-ment of minimally invasive surgery in biliary tract cancer has encountered more difficulties and controversies. As one of the representative fields of modern precise surgery and an important part of multidisciplinary therapy, the value and application of minimally invasive surgery in the treatment of biliary tract cancer need to be further elaborated and standardized. Minimally invasive surgical techniques should be explored and studied under reasonable norms and supervision. More higher level evidence‑based evidences should be obtained under the premise of ensuring the ethical prin-ciple of maximum benefit to patients, and ultimately promote the overall progress in the field.
