Conventional open thyroidectomy is a safe procedure, but it has the disadvantage of leaving noticeable scars on the neck. Bilateral axillo-breast approach (BABA) robotic thyroidectomy was developed as an alternative technique to remove thyroid glands without making incisions in the neck. In traditional BABA robotic thyroidectomy, dividing the isthmus is a routine step to improve the efficiency of the dissection during thyroid surgery. However, there are safety concerns when performing this procedure on patients with thyroid cancer located in the isthmus. We report a case of BABA robotic total thyroidectomy carried out without dividing the isthmus in a patient with isthmic papillary thyroid carcinoma. Our experience suggests that BABA robotic surgery can be a feasible and safe option for selected patients with isthmic papillary thyroid carcinoma.
2.An institutional experience of intraoperative neurophysiological monitoring application in robotic thyroidectomy: a retrospective case-control study
Annals of Surgical Treatment and Research 2024;106(5):243-247
Purpose:
Intraoperative neurophysiological monitoring (IONM) has been introduced in thyroid surgery to prevent injury of the recurrent laryngeal nerve (RLN). However, its effectiveness remains controversial in robotic thyroidectomy (RT). This study aimed to compare the surgical outcome of RT in patients with and without the application of IONM.
Methods:
This retrospective case-control study included 100 patients who underwent total thyroidectomy via robotic bilateral axillo-breast approach in a tertiary center. A study group of 50 patients who had IONM during RT was compared to a control group of 50 patients who underwent RT with nerve visualization alone.
Results:
The sex ratio (4:45 vs. 7:43, P = 0.538), mean age (39.3 ± 7.1 years vs. 37.5 ± 10.4 years, P = 0.304), and body mass index (23.1 ± 2.6 kg/m2 vs. 22.2 ± 3.9 kg/m2 , P = 0.215) were comparable between the IONM and control groups. Pathologic features including tumor size (0.8 cm vs. 0.9 cm, P = 0.283), extrathyroidal extension (58.0% vs. 24.0%, P = 0.316), lymph node metastasis (30% vs. 34%, P = 0.668), and number of lymph nodes (5.3 vs. 5.3, P = 0.668) showed no differences. There was no permanent RLN palsy, postoperative bleeding, and wound complications. Transient hypoparathyroidism was observed in 12 (24.0%) and 14 (28.0%), permanent hypoparathyroidism in 0 (0%) and 1 (2.0%), and transient RLN palsy was observed in 3 (6.0%) and 3 (6.0%), respectively.
Conclusion
We did not demonstrate a clear advantage of IONM in RT. Controversies regarding the effectiveness of IONM is not closed.

PURPOSE: Anaplastic thyroid cancer (ATC) is rare and has a poor prognosis. The aim of this study was to analyze the clinicopathologic characteristics of patients diagnosed with ATC expected to undergo curative thyroidectomy, with the goal of finding differences between patients surviving > or =6 months and <6 months. METHODS: From 1981 to 2010, 24 patients underwent thyroidectomy due to ATC. Among those patients, 12 suspected of distant metastasis preoperatively were excluded. The remaining 12 patients were analyzed by retrospective review of electronic medical records. RESULTS: Median age was 55 years, and the male to female ratio was 1:5. All patients presented with neck mass at initial diagnosis. Five patients lived <6 months and seven patients lived > or =6 months after operation. In patients surviving > or =6 months, all lesions were <5 cm and all patients underwent total thyroidectomy. In patients surviving <6 months, two of the four lesions were >5 cm, and two of the five patients underwent less than total thyroidectomy (P = 0.287 and 0.152, respectively). All patients with lesion size <5 cm underwent total thyroidectomy and showed a shorter median operation time (P = 0.182 and 0.033, respectively). CONCLUSION: ATC showed female predominance. Patients initially presented with neck mass, and median age was 55 years. In patients with ATC who are expected to undergo curative thyroidectomy, surgery should actively be considered as primary therapy for patient survival when the size is <5 cm.

PURPOSE: Routine supplementation of high-dose calcium significantly decreased the risk of postoperative symptomatic hypocalcemia after thyroidectomy. However, there is an ongoing debate about whether the same results can be achieved with low-dose calcium supplementation. METHODS: Patients (n = 138) who underwent total thyroidectomy for thyroid cancer were 1:1 randomly assigned to receive oral supplements of 1,500 mg/day elemental calcium and 1,000 IU/day cholecalciferol for 2 weeks or no supplementation. Primary objective was to compare the incidence of symptomatic hypocalcemia for 3 days after total thyroidectomy. Secondary objective was to find the predictors for postoperative hypocalcemia in patients with thyroid cancer. RESULTS: Sixty-five patients in the calcium group and 69 patients in the control group were finally analyzed. The incidence of symptomatic hypocalcemia showed no difference between the calcium and control group (32.3% vs. 21.7%, P = 0.168). The total dosage of intravenous calcium (593.4 ± 267.1 mg vs. 731.6 ± 622.7 mg, P = 0.430) administered to patients with symptomatic hypocalcemia was also comparable between groups. In a multivariate analysis, parathyroid hormone level of 13 pg/mL at postoperative day 1 was only predictive for symptomatic hypocalcemia, and its incidence was 20.9 times (95% confidence interval, 6.8–64.5) higher in patients with parathyroid hormone <13 pg/mL. Other factors did not predict the development of hypocalcemia, including clinicopathological features and routine supplementation of low-dose calcium. CONCLUSION: Routine low-dose calcium supplementation did not reduce the risk of postoperative hypocalcemia. Patients who may benefit from calcium supplementation should be carefully selected.

Active surveillance (AS) of papillary thyroid microcarcinoma was first suggested by Dr. Akira Miyauchi at Kuma Hospital in 1993. Based on several subsequent evidences, AS was approved by the American Thyroid Association in 2015. AS is no longer an experimental treatment but has become an acceptable standard of care for patients with low-risk thyroid cancers. No molecular markers, such as BRAF mutations, have been identified to predict the prognosis of papillary thyroid cancer. However, future molecular studies may reveal the relationship between genetic mutations and thyroid cancer prognosis. AS involves closely monitoring thyroid cancer over time, instead of immediately treating it with surgery. Patients and medical doctors should consider these two options: observation or surgery.

PURPOSE: Surgical excision is the definitive treatment for localized recurrence of papillary thyroid carcinoma. Reoperation for recurrence, however, is challenging and associated with increased operative times and complication rates. For safe and effective reoperation, ultrasound-guided charcoal tattooing localization can be used. The aim of this study was to investigate the feasibility and safety of the ultrasound-guided charcoal tattooing localization. METHODS: Between November 2012 and August 2013, ten patients underwent preoperative charcoal tattooing localization for twelve recurrent lesions. Patient demographics, pathologic features, and operation results were reviewed. RESULTS: The technical success rate of charcoal tattooing was 100%. Eight patients had one recurrent lesion, and two patients had double lesions. Among these 12 recurrent lesions, three (25%) were found in level II, four (33%) in level IV, four (33%) in level VI, and one (8%) was found in the thyroidectomy bed site. The mean size of lesions was 0.87 +/- 0.35 cm. Of these 10 patients, eight patients underwent selective lymph node dissection, one patient underwent modified radical neck dissection, and one patient underwent recurrent mass excision. Transient hypocalcemia developed in one patient, and no recurrent laryngeal nerve palsy occurred. There were no major complications related to the injection of the charcoal. The mean follow-up period after reoperation was 8.6 +/- 2.7 months; in the follow-up ultrasound, there were no remnant lesions in all patients. CONCLUSION: Preoperative ultrasound-guided charcoal tattooing localization for recurrent thyroid cancer appears to be a feasible and safe procedure for reoperation. Further evaluation is warranted in larger patients' cohorts.

PURPOSE: Postoperative pain for robotic thyroid surgeries including bilateral axillo-breast approach (BABA) has not been well studied. In this study, we have developed a self-reporting application (SRA) for iPad and prospectively collected pain scores from open thyroidectomy (OT) and BABA robotic thyroidectomy (RT) patients. METHODS: Female patients who underwent total thyroidectomy for papillary thyroid carcinoma were included. Patients recorded pain scores for throat, anterior neck, posterior neck, chest, and back on postoperative days 1, 2, and 3. Once discharged, on postoperative day 14, a survey was also conducted on satisfaction of SRA and cosmesis. RESULTS: A total of 54 patients were enrolled (27 BABA RT and 27 OT). There were no significant differences between the 2 groups in clinicopathological characteristics and postoperative complication rates. Postoperative pain scores at days 1, 2, 3, and 14 were not significantly different between the groups for throat, anterior neck, posterior neck, or back. Postoperative analgesic requirements were similar between the 2 groups. Wound satisfaction scores were significantly higher in the BABA RT group (BABA RT 7.4 vs. OT 5.7; P = 0.016). Satisfaction scores for the usefulness of SRA were above 7.2 for all four questionnaire items on the 10-point scale. CONCLUSION: Postoperative pain for BABA RT is equivalent to OT but offers greater cosmetic satisfaction for patients. A mobile device application such as SRA may facilitate proper assessment and management of pain in postoperative patients.

PURPOSE: Primary thyroid lymphoma (PTL) is a rare disease and it has been investigated in a limited number of studies. The present multicenter study evaluated the clinical features and treatment outcomes of PTL. METHODS: The medical records of patients diagnosed with PTL between 2000 and 2013 in three centers were retrospectively reviewed. RESULTS: The study included 11 men and 27 women with a median age of 63.3 years (range, 42-83 years). The median follow-up was 56.0 months (range, 3-156 months). Of the 38 patients included, 16 had mucosa-associated lymphoid tissue (MALT) lymphoma, six had mixed MALT and diffuse large B-cell lymphoma (DLBCL), and 16 had DLBCL. Thirty-five patients (92.1%) had early stage (stage I/II) disease. Of the 16 MALT lymphoma patients, 14 were treated by surgery, and radiotherapy (RT) or chemotherapy was combined in five patients. Two patients received RT or chemotherapy alone. Of the six mixed MALT and DLBCL patients, three underwent surgery with chemotherapy and three underwent chemotherapy alone, RT alone, or surgery with RT. All of the 16 DLBCL patients received chemotherapy, and surgery and RT was combined in 4 and 1 patients, respectively. The 5-year survival was 100% for MALT lymphoma (7 of 7) and mixed MALT and DLBCL patients (5 of 5) and 87.5% for DLBCL patients (7 of 8). CONCLUSION: Early stage PTL has an excellent prognosis when managed by single or combined treatment modalities. Clinicians should consider PTL in patients with underlying Hashimoto's thyroiditis presenting with an enlarging thyroid mass.

PURPOSE: Endoscopic thyroidectomy using a cervico-axillary approach (CAA) provides optimal visualization with a smaller dissection plane. Despite the excellent cosmetic results and high patient satisfaction, the surgical and oncologic safety of CAA endoscopic surgery has not been fully established. The present study evaluated the feasibility, safety, and surgical outcomes of CAA endoscopic thyroidectomy. METHODS: From October 2009 to April 2012, 100 patients with papillary thyroid cancer underwent CAA endoscopic thyroidectomy. Patient demographics, pathologic features, and surgical outcomes including complications and recurrence were collected. RESULTS: CAA endoscopic thyroidectomy was successful in all patients, and none required conversion to open thyroidectomy. All patients underwent ipsilateral thyroid lobectomy with or without central compartment neck dissection. The mean tumor size was 1.0±0.6 cm (range, 0.5~1.6), and 35.0% of tumors showed extrathyroidal extension. The mean number of harvested lymph nodes was 4.1±4.4, and metastasis was found in 12.0% of patients. The mean surgical time was 175.2±50.4 min, mean intraoperative blood loss was 42.5±69.2 ml, and the mean hospital stay was 3.3±0.6 days. There were five cases of postoperative transient hypocalcemia and eight cases of vocal cord palsy. No permanent complication or postoperative bleeding was observed. Patients continued to be seen for a median period of 63.7 months, and no recurrence of thyroid cancer was seen. CONCLUSION: CAA endoscopic thyroidectomy is a feasible and safe procedure for low-risk thyroid cancer, with excellent cosmesis. It can be recommended as an alternative option for selected patients with low-risk thyroid cancer.
