Abstract
Although the Institut Mutualiste Montsouris (IMM) classification has been widely applied and validated for laparoscopic liver resections (LLRs), it has not been well-validated for robotic liver resections (RLR) in a large sample of patients. An international multicenter study to validate the IMM difficulty scoring system (DSS) across three complexity levels and 11 procedure types was conducted to address current limitations in studies validating the IMM DSS for RLR.
