Minimally invasive endoscopic thyroid surgery using a collar access: experience in 246 cases with the CEViTS technique.

ABSTRACT

BACKGROUND: The arguments for applying minimally invasive techniques are, besides cosmetic results, reduced access trauma and less postoperative pain. In thyroid surgery, cosmetic aspects are gaining importance. Whether minimally invasive endoscopic thyroid surgery is less painful has not been shown yet. METHOD: In this study, we analyse the outcome of 246 patients who underwent cervical endoscopic video-assisted thyroid surgery (CEViTS) regarding the surgery itself, their postoperative pain and satisfaction with the procedure. RESULTS: CEViTS is routinely performed in our hospital. In this study, no postoperative bleedings that would have made a reoperation necessary occurred. All lobectomies could be completed endoscopically. In two cases, conversions (enlargement of the 5-mm incision to 25 mm) were necessary. Transient nerve palsy was registered in three patients (1.22%). One patient (0.41%) had a permanent palsy of the recurrent laryngeal nerve. In comparison to open surgery (n = 173 patients), the 246 CEViTS patients had a significantly lower pain level (p = 0.047). CONCLUSIONS: Cervical endoscopic video-assisted thyroid surgery (CEViTS) can be considered a safe, less traumatizing and useful minimally invasive procedure in endoscopic thyroid surgery.
