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.

OBJECTIVES: Previous studies have suggested that information processing impairment is the main pathophysiology of post-traumatic stress disorder (PTSD). The P300 event-related potential (ERP) has been widely used, in diseases with cognitive dysfunction, such as schizophrenia and Alzheimer's disease, for detecting abnormality in information processing. This study examined P300 characteristics of PTSD patients. METHODS: We recruited 23 patients (mean age 44.35) who met DSM-IV criteria for PTSD and matched 24 normal control (NC) subjects by age and education level. The NC group had no personal history of psychiatric or neurological abnormality. We conducted the Korean version of the structured interview for PTSD (K-SIPS) and Davidson trauma scale (DTS) with the PTSD patients. Then we measured P300 amplitude and latency on 3 electrodes (Cz, CPz, Pz) in both PTSD patients and the NC group. RESULTS: Compared with the NC, the P300 amplitudes of PTSD patients were lower on Cz (PTSD: NC=5.51+/-2.82 uV : 11.80+/-5.18 uV, p<0.01), CPz (PTSD : NC=5.84+/-2.71 uV : 12.69+/-4.51 uV, p<0.01) and Pz (PTSD : NC=5.01+/-2.60 uV : 10.99+/-4.24 uV, p<0.01). We found increasing tendency toward P300 latency in PTSD group compared with NC. However, the BDI and DTS symptom severity scores were negatively correlated with the P300 amplitude of Pz. CONCLUSION: There was a significant reduction of P300 amplitudes in PTSD patients. Compared to NC group, PTSD patients showed a reduced P300 amplitude significantly correlated with symptom severity. The present findings suggest PTSD patients experience cognitive dysfunction and ERP P300 can be a useful surrogate marker of symptom severity in PTSD patients.

Bleeding from pancreatic pseudocyst is a rare complication. Furthermore, massive upper gastrointestinal (GI) bleeding from gastro-cystic fistula formation and intracystic bleeding are both extremely rare and are also potentially fatal. A 53-year-old male was referred to the emergency room with melena and hematemesis. An urgent endoscopy revealed a massive gastric hematoma but showed no specific bleeding focus. Gastrocystic fistula formation and intracystic bleeding leakage to the stomach were suspicious in the follow-up endoscopy. A contrast-enhanced computed tomography scan demonstrated splenic artery pseudoaneurysm and extravasation of contrast media into the cyst that was abutted to the greater curvature side of the stomach. A splenic artery embolization was performed and no further bleeding occurred after embolization. Upper GI bleeding from gastro-cystic fistula and intracystic bleeding are rare but possible. Therefore, this possibility should be considered in the unknown cause of an upper GI bleeding in a patient with pancreatic pseudocyst.

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: 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.

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.
