Radio-guided occult lesion localization (ROLL) safely identified and removed a difficult-to-find recurrent ovarian cancer lesion in the mesorectum. This technique offers a precise method for excising challenging oncologic recurrences.
Area of Science:
- Oncology
- Surgical Innovation
- Medical Imaging
Background:
- Radio-guided occult lesion localization (ROLL) is established for breast surgery.
- ROLL is increasingly applied to various oncologic pathologies.
- Accurate localization is crucial for complete tumor excision.
Observation:
- A solitary 11-mm mesorectal recurrence of primary ovarian cancer was identified.
- Endoscopic ultrasound-guided radioisotope injection was performed.
- A gamma probe guided surgical incision and excision.
Findings:
- The ROLL technique successfully identified the mesorectal lesion.
- Complete macroscopic excision of the recurrent lesion was achieved.
- Post-excision radioactivity measurement confirmed tissue removal.
Implications:
- This case demonstrates the first use of ROLL for mesorectal lesion excision.
- ROLL offers a safe and effective method for difficult-to-identify recurrences.
- The technique has potential for broader application in oncologic surgery.
