Objective:To explore the feasibility and efficiency of intraoperative ultrasonography(IOUS)in the cool-tip ra- diofrequency ablation(RFA)of hepatic carcinoma.Methods:Thirty-one patients of hepatic carcinoma were enrolled in this study.In the process of open-surgical cool-tip radiofrequency ablations,IOUS was applied to assess the hepatic lesions, guide and monitor the process of RFA in real-time.Results:Under the guidance of intraoperative ultrasonography,the open surgical RFA in all patients proceed smoothly.Seven additional hepatic lesions were found that were not detected in preop- erative imaging.A false positive focal lesion reported by preoperative MRI was accurately ruled out by IOUS.Conclusion: Intraoperative ultrasonography is superior to ordinary imaging techniques in finding missed lesions,avoiding complications such as injuries of bile ducts and vessels.Monitoring the real-time RFA process thereby obviously optimizing the treatment of hepatic carcinoma.
Objective: To explore the feasibility and efficiency of intraoperative ultrasonography (IOUS) in the cool-tip ra-diofrequency ablation (RFA) of hepatic carcinoma. Methods: Thirty-one patients of hepatic carcinoma were enrolled in this study. The process of open -surgical cool-tip radiofrequency ablations, IOUS was applied to assess the hepatic lesions, guide and monitor the process of RFA in real-time. Results: Under the guidance of intraoperative ultrasonography, the open surgical RFA in all patients proceed smoothly. Seventh additional hepatic lesions were found that were not detected in preop- erative imaging. A false positive focal lesion reported by preoperative MRI was accurately ruled out by IOUS. Confound: Intraoperative ultrasonography is superior to ordinary imaging techniques in finding missed lesions, avoiding complications such as injuries of bile ducts and vessels. Monitoring the real-time RFA process thereby substantially optimizing the treatment of hepatic carcinoma.
