Influence of surgical margin width on survival rate after resection of intrahepatic cholangiocarcinoma: a systematic review and meta-analysis.

Patients with ICC who underwent curative hepatectomy with a negative margin ≥10 mm may have a long-term survival advantage, but lymph node dissection also needs to be considered. In addition, tumour-related pathological features need to be explored to see if they affect the surgical outcome of R0 margins.
