Imaging-Guided Preoperative Localization of Intra-Abdominal Local Recurrences of Colorectal Cancer Using the Harpoon Technique.

Background and Aims: Intra-abdominal local recurrences of colorectal cancer can be difficult to localize and excise because they are not easily visible or palpable. Materials and Methods: We report on our experience using the computed tomography-guided harpoon technique to locate and resect these nodules in seven patients. Results: No complications were recorded during the procedures. Six nodes were malignant and all margins were tumor free. Conclusions: Harpoon placement for intra-abdominal local recurrences of colorectal cancer is a feasible and useful technique that provides direct localization and complete excision of lesions.
