PURPOSE: Endoscopic and robot-assisted thyroidectomy has shown rapid development worldwide. In addition, there is no treatment of choice for thyroidectomy as usual. We propose an endoscopic thyroidectomy using a cervico-transaxillary approach, comparing its results with those of robot-assisted thyroidectomy. We present this study in order to provide advantages and disadvantages. METHODS: Between January 2010 and March 2012, 132 patients were recruited with clinicopathological data for this study. We divided patients into two groups, the endoscopic and the robot groups, with respect to their clinical characteristics, surgical outcomes. The outcomes were evaluated in terms of operation time, estimated blood loss, hemovac amount, hospital stay, and number of lymph nodes harvested. RESULTS: A total of 132 patients (male 6 and female 126) were recruited with clinicopathological data for this study. Of these, 78 patients underwent endoscopic thyroidectomy (the endo group) and 54 underwent robot-assisted thyroidectomy (the robot group) using a cervico-transaxillary approach. The two groups did not differ significantly in terms of age, estimated blood loss, and complications. None of the patients experienced severe complications. CONCLUSION: Results of the preliminary comparison in this study show that both approaches are safe and feasible, with similar results. However, a smaller hemovac amount was observed with endoscopic thyroidectomy, compared to robot-assisted thyroidectomy. In order to cut costs, part of robot-assisted thyroidectomy could be replaced by endoscopic thyroidectomy.

PURPOSE: Adrenal schwannomas are very rare and are usually incidentally found on autopsy and imaging. The aim of this study was to describe our experience of adrenal schwannoma and review the literature regarding this rare tumor. METHODS: To identify patients with adrenal schwannoma, the MEDLINE database was searched via the major electronic database PubMed using the medical subject heading terms “adrenal” and “schwannoma”. Thirty-nine adrenal schwannoma cases, including two from our institution were included. RESULTS: The mean age at diagnosis was 47.95 years (range, 11~89 years). The female:male ratio was 21:17. Sixteen patients had tumors on the right side, 19 on the left, while one patient had bilateral tumors. The mean tumor size was 6.12 cm (range, 0.6~14.5 cm), and the mean tumor weight was 161.3 g (range, 31.5~600.0 g). Sixteen tumors were solid, four cystic, one solid and cystic, and 18 were not described. Histologically, 14 cases were Antoni A, two were Antoni B, and 12 had concomitant Antoni A and B. CONCLUSION: Adrenal schwannoma is usually an incidental finding, and the clinician must have a high index of suspicion to recognize it when imaging reveals suggestive features.

PURPOSE: Although minimally invasive follicular thyroid carcinoma (MIFTC) is considered a thyroid tumor with low malignant potential, some MIFTC can spread, metastasize, and eventually lead to death. This study investigates the risk factors for distant metastasis in MIFTC patients. METHODS: Between 1981 and 2014, the records of 365 consecutive patients who underwent thyroidectomy for MIFTC at Seoul National University Hospital were reviewed. Univariate and multivariate analyses were performed to identify risk factors associated with distant metastasis. RESULTS: Of 351 patients, 10 (2.9%) presented with distant metastasis. Of these, two (0.6%) were found at the time of thyroidectomy, while eight (2.3%) were detected at later exams, over a median of 7.3 years (range, 0.2~30.8). In univariate analysis, lymph node metastasis (P<0.001) was significantly associated with distant metastasis. In multivariate analysis, lymph node metastasis (P<0.001) and locoregional recurrence (P=0.008) were significantly associated with distant metastasis. CONCLUSION: Distant metastasis in MIFTC patients were associated with high-risk clinicopathologic features and more aggressive clinical courses. Further study will be needed to ascertain these results with long-term surveillance.

PURPOSE: Postoperative adhesion after thyroidectomy results in neck discomfort and swallowing difficulty. However, risk factors for adhesive symptom after thyroidectomy have not been well studied. This study evaluated symptoms related to postoperative adhesion after thyroidectomy. METHODS: The Glasgow-Edinburgh Throat Scale (GETS) questionnaire was used to evaluate postoperative adhesion. Patients who completed the GETS questionnaire either pre- or post-operatively were enrolled. Patient clinical and pathological details including age, gender, body weight, body mass index (BMI), tumor size, thyroid volume, extent of thyroidectomy, postoperative months, and neck thickness on ultrasonography and computed tomography (CT) were abstracted. RESULTS: Twenty-eight preoperative (22 females, six males) and 101 postoperative (83 females, 18 males) patients were enrolled. The mean age of the pre-operative enrollees was 52.1±11.7, and of post-operative enrollees 51.8±12.4 years. Patients who were within one month post-surgery had higher GETS scores than preoperative patients (27.4±20.1 vs. 6.5±11.1, P<0.001). Two months after surgery, GETS scores of postoperative patients did not differ significantly from the scores of the preoperative patients. There were no significant associations between clinical and pathologic features (age, tumor size, BMI, neck thickness on ultrasonography and CT) and GETS scores. CONCLUSION: Postoperative adhesive symptoms were most severe at one month after surgery, while questionnaire scores two months after surgery were comparable with preoperative patients. Further studies will be required for better understanding of the natural course of postoperative adhesion after thyroidectomy.
