Background: The management of patients with synchronous colorectal liver metastases (sCRLM) has evolved significantly (improved chemotherapy, hepatic surgery advancements, colonic stenting, consultation synergies). We sought to better understand surgeon viewpoints on optimal referral patterns and the delivery of simultaneous resections.
Methods: A 40 question on-line survey was offered to members of the Canadian surgical community. Statistical analysis was descriptive.
Results: A total of 52 surgeons responded. Most colorectal surgeons (CRS) had access to and a good working relationship with regional hepatobiliary (HPB) surgeons (86%) and medical oncologists (100%). The majority (92%) believed there was a role for simultaneous resection of sCRLM, with 69% having first hand experience. Many CRS (62%) discussed all cases of known hepatic metastases with HPB prior to any resection. When a lesion was asymptomatic/minimally symptomatic, most CRS (92%) discussed them with medical oncology/HPB prior to resection (8%). Bilobar metastases (58%), patient comorbidities (35%), portal lymphandenopathy (35%), and patient age (15%) restricted CRS from obtaining HPB consultations. Many CRS (46%) did not believe that resecting hepatic metastases prior to the primary lesion might be beneficial. Most CRS (60%) reported they could not accurately predict hepatic resectability, with only 27% familiarity with evidence-based guidelines. Despite working in smaller hospitals with less access to HPB and less experience with simultaneous resections, non-CR general surgeons more commonly supported a ‘liver-first’ approach.
Conclusions: There was general agreement between CRS and general surgeons on numerous topics, but additional education is required with regard to HPB surgical capabilities and to provide truly individualized patient-centered care.
