Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver cancer with a poor prognosis. Negative-margin resection is presently the only potentially curative treatment option. Emerging trends with direct applicability to surgical strategy include margin thickness, lymphadenectomy, optimization of future liver remnant (FLR), minimally invasive techniques, incorporation of systemic therapy, and reconsideration of liver transplantation. This review emphasizes areas of consensus and ongoing debate. Margins ≥5–10 mm are associated with improved results, but biology generally takes precedence over prognosis. Regional lymphadenectomy enhances staging accuracy, although its therapeutic benefit remains unsettled. PVE is standard for FLR enlargement, LVD provides faster hypertrophy, and ALPPS remains reserved for highly selective cases. Minimally invasive and robotic hepatectomy share oncologic results in skilled institutions. Systemic therapies, including immunotherapy and biomarker-directed targeted therapy, are increasingly being incorporated perioperatively. Liver transplant may be of potential value in early-stage disease or on strict indications after neoadjuvant treatment. The modern surgical management of iCCA encompasses a blend of oncologic considerations, FLR optimization, minimally invasive surgery, and systemic therapy according to tumor biology. Multidisciplinary planning and participation in clinical trials are necessary to align surgical innovation with advancements in molecular and systemic treatments, ultimately leading to improved long-term outcomes.
