[Repeat liver resection in colorectal liver metastases]

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Colorectal Cancer Management

Context:

• Colorectal cancer frequently metastasizes to the liver, posing a significant challenge for long-term patient survival.
• Operative resection remains the only curative option for liver metastases, with repeated resections gaining attention due to limited alternatives.
• The study focuses on recurrent, operable liver metastases from colorectal cancer, evaluating the efficacy of repeat surgical interventions.

Purpose:

• To evaluate the outcomes of repeated liver resections in patients with recurrent colorectal cancer metastases.
• To assess the safety and efficacy of repeat hepatectomies in terms of complication rates and survival.
• To compare the survival benefit of operative resection versus non-operative management for liver metastases.

Summary:

• Twelve recurrent liver resections were performed on 8 patients with colorectal cancer metastases between 1986 and 1994.
• Procedures included anatomic hemihepatectomy, segmentectomy, or bisegmentectomy, with a mean interval of 14 months between resections.
• Postoperative complication rate was 16% with no in-hospital mortality; 5 patients are alive with a mean follow-up of 14 months, 3 of whom are tumor-free.

Impact:

• Repeated liver resections can achieve prolonged survival times for select patients with colorectal liver metastases.
• This approach offers a potential for long-term disease control and improved quality of life.
• The findings support considering operative risk and patient selection for repeat liver resections in managing metastatic colorectal cancer.
