Removal of Benign Superficial Masses Using the TriVex System: Preliminary Clinical Results.
BACKGROUND AND OBJECTIVE
Transilluminated powered phlebectomy using the TriVex system is a new procedure for minimally invasive varicose vein surgery. We used the TriVex system for the removal of benign superficial subcutaneous soft tissue masses, and we also achieved satisfactory clinical effects. The objective of this study was to explore the feasibility, benefits, and technique-related complications of using the TriVex system for the removal of benign superficial masses as a novel and minimally invasive surgical technique.


METHOD
Between January 2010 and August 2016, 452 patients with benign superficial soft tissue masses underwent surgical removal of masses using the TriVex II system in our department. The surgical complications, postoperative cosmetic outcome, and personal satisfaction were reviewed at a mean follow-up of 24 months.


RESULTS
The TriVex procedure was successfully completed in all patients using only local tumescent anesthesia without any technical problem and serious complications. The mean operation duration was 8.5 minutes, and the average blood loss was 5 mL. Surgical complications were observed in 69 cases (15.3%) of subcutaneous ecchymosis, 34 cases (7.5%) of skin perforation, 14 cases (3.1%) of subcutaneous hematoma, 13 cases (2.9%) of wound infection, and 7 cases (1.5%) of induration of operation area. Eleven patients (2.4%) showed recurrence during the follow-up and were cured by reoperation by the TriVex system. Overall, the majority of patients (N = 436, 96.5%) were very satisfied or satisfied with the outcome.


CONCLUSION
The TriVex procedure for the removal of benign superficial masses is simple, safe, and effective with advantages of short operation time, small incisions, and good cosmetic outcome, which is predicted as a new minimally invasive surgery of superficial masses.
