Summary
The computed tomography-guided harpoon technique effectively locates and resects difficult-to-find colorectal cancer recurrences. This method ensures complete tumor removal with no complications, improving patient outcomes.
Area of Science:
- Oncology
- Surgical Oncology
- Medical Imaging
Background:
- Intra-abdominal colorectal cancer recurrences pose localization and excision challenges due to poor visibility.
- Accurate identification of these lesions is critical for effective treatment and patient prognosis.
Purpose of the Study:
- To evaluate the efficacy and safety of the computed tomography-guided harpoon technique for localizing and resecting intra-abdominal colorectal cancer recurrences.
Main Methods:
- The study involved seven patients with intra-abdominal colorectal cancer recurrences.
- A computed tomography-guided harpoon technique was employed for lesion localization and resection.
Main Results:
- The computed tomography-guided harpoon technique was successfully implemented in all seven patients.
- Six of the resected nodules were confirmed as malignant.
- All excisions achieved tumor-free margins, indicating complete resection.
Conclusions:
- The harpoon placement technique is a feasible and valuable method for intra-abdominal colorectal cancer recurrence management.
- This technique facilitates direct localization and complete excision of elusive lesions.
