Background:
Since the introduction of endoscopic techniques in thyroid surgery, several trials of endoscopic lateral neck dissection have been conducted with the aim of avoiding a long cervical scar, but these endoscopic procedures require more effort than open surgery, mainly because of the relatively nonsophisticated instruments used. However, the recent introduction of surgical robotic systems has simplified the operations and increased the precision of endoscopic techniques. We have described our initial experience with robot-assisted modified radical neck dissection (MRND) in thyroid cancer using the da Vinci S system.
Methods:
From October 2007 to October 2009, 33 patients with thyroid cancer with lateral neck lymph node (LN) metastases underwent robot-assisted thyroidectomy and additional robotic MRND using a gasless, transaxillary approach. Clinicopathologic data were analyzed retrospectively.
Results:
Mean patient age was 37 ± 9 years and the gender ratio (male to female) was 7:26. The mean operating time was 281 ± 41 minutes and mean postoperative hospital stay was 5.4 ± 1.6 days. The mean tumor size was 1.1 ± 0.5 cm and 20 cases (61%) had papillary thyroid microcarcinoma. The mean number of retrieved LNs was 6.1 ± 4.4 in the central neck compartment and 27.7 ± 11.0 in the lateral compartment. No serious postoperative complications, such as Horner's syndrome or major nerve injury, occurred.
Conclusion:
Robot-assisted MRND is technically feasible, safe, and produces excellent cosmetic results. Based on our initial experience, robot-assisted MRND should be viewed as an acceptable alternative method in patients with low-risk, well-differentiated thyroid cancer with lateral neck node metastasis.
