Order of colon versus liver removal during simultaneous surgery for colorectal cancer with liver metastases

Official title: Comparison of the Resection Site Order in Simultaneous Approach of Colorectal Liver Metastasis. An International Multicentric Retrospective Trial.

Run by Azienda Ospedaliera SS. Antonio e Biagio e Cesare Arrigo di Alessandria · NCT07272928 · Data updated 2026-11-12

This project tries to see if doing the liver operation before the colon or the colon before the liver changes outcomes for adults having both surgeries at the same time for colorectal cancer that has spread to the liver.

Is this trial a fit for you?

Likely a good fit

Adults with colorectal cancer and synchronous liver metastases who underwent planned simultaneous colon and minor liver resections at the enrolling center and who are ASA class 3 or lower are the ideal candidates for inclusion.

Probably not a fit

Patients undergoing emergency surgery, those with extrahepatic metastatic disease, those at very high surgical risk (ASA > 3), or those needing major hepatectomy are unlikely to benefit from findings applicable to elective simultaneous resections of minor liver lesions.

What this trial studies

This is an observational analysis comparing outcomes by resection order in patients who underwent simultaneous colon and liver removal for colorectal cancer with synchronous liver metastases. Participating cases come from a single surgical center and include minimally invasive and open approaches, with exclusion of emergency resections, extrahepatic disease, and high surgical-risk patients (ASA > 3). Key outcomes include intraoperative blood loss, postoperative complications including anastomotic healing, length of stay, and time to chemotherapy, with at least six months of follow-up required. The study aims to clarify whether resection order affects perioperative results when minor hepatectomies are paired with standard colon resections.

Why it matters

Potential benefit: If a clear advantage to one resection order is found, surgeons could adopt that sequence to reduce blood loss, lower complication rates, shorten hospital stays, and allow earlier chemotherapy for eligible patients.

How similar studies have gone: Previous observational series and comparative reports suggest simultaneous resection with minor hepatectomy is safe and that minimally invasive approaches have similar morbidity and oncologic outcomes to open surgery, but data on the optimal resection order are limited and inconsistent.
