Objective:To compare the clinical effects of endoscopic thyroidectomy using the modified gasless transaxillary approach (TA group) and transsubclavian approach (TS group) in the treatment of cN0 papillary thyroid carcinoma (PTC) .Methods:A total of 190 PTC patients (mean age 39.88±9.35 years,38 males, 152 females), who underwent unilateral thyroidectomy in the Department of Thyroid Surgery, the First Hospital of Jilin University from Oct. 2020 to Oct. 2022 were retrospectively analyzed, including 65 cases in TA group, 43 cases in TS group and 82 cases through traditional neck approach (TN group). The endoscopic group (TA+TS) consists of the TA group and the TS group. Comparative analyses were performed on operation time, full exposure rate of central compartment, postoperative hospitalization time, postoperative drainage, hospitalization costs, the number of dissected lymph nodes and postoperative complications. The t-test or Wilcoxon rank sum test, the χ2 test or the exact probability method were used for statistical analysis. Results:All endoscopic operations were successfully completed without conversion to traditional neck approach. ① Compared with the TN group, the endoscopic group (TA+TS) had longer operation time[TN group =74.5 (65-87) min, (TA+TS) group =102 (89-121) min, P<0.001], lower full exposure rate of central compartment (TN group=100%, (TA+TS) group=89.8%, P=0.008), more postoperative drainage[TN group=60 (45-76) ml, (TA+TS) group =100 (80-130) ml, P<0.001], higher hospitalization costs[TN group=¥23638 (22158-25901), (TA+TS) group =¥26967 (25572-28284), P<0.001], and higher parathyroid autotransplantation rate (TN group=4.9%, (TA+TS) group =50.9%, P<0.001). There were no significant differences in the number of dissected lymph nodes, the number of metastatic lymph nodes, preoperative and postoperative parathyroid hormone (PTH) ( P>0.05). ② Compared with the TS group, the TA group had longer operation time[TA group=110 (97-127) min, TS group=89 (80-111) min, P<0.001], lower full exposure rate of central compartment (TA group=83.1%, TS group=100%, P=0.012), longer postoperative hospitalization time[TA group=3 (3-4) d, TS group=3 (3-3) d, P=0.002], more postoperative drainage[TA group=110 (82-140) ml,TS group=95 (65~120) ml, P=0.046] and higher hospitalization costs (TA group=¥27510±2578,TS group=¥26609±1878, P=0.038). There were no significant differences in the number of dissected lymph nodes, the number of metastatic lymph nodes, preoperative and postoperative PTH, and parathyroid autotransplantation between the two groups ( P>0.05) . Conclusions:Endoscopic thyroidectomy through axillary/subclavian approach is safe and feasible for the treatment of cN0 PTC. There was no significant difference in the number of dissected central lymph nodes compared with conventional surgery, and the incision was well concealed. In comparison, transsubclavian endoscopic surgery has better clinical application value, with shorter operation time, higher full exposure rate of central compartment and faster postoperative recovery.

According to the cause of hyperparathyriodism (HPT) , it can be divided into three types: primary hyperparathyroidism (PHPT) , secondary hyperparathyroidism (SHPT) and tertiary hyperparathyroidism (THPT) . THPT is a state of excessive autonomous excretion of parathyroid hormone (PTH) after longstanding SHPT. In the past, reports of THPT is relatively rare in domestic, which may be related to the understanding and experience of clinicians. With the increase of kidney transplant cases all over the word, the incidence rate has also gradually increased. Therefore, it is especially important to deepen the knowledge of THPT, standardize the medical treatment, and strictly control the indications for surgery.

Hyalinizing trabecular tumor (HTT) is a primary thyroid tumor discovered 20 years ago. This tumor is usually misdi-agnosed as papillary thyroid carcinoma because of their many similar nuclear features. Although controversy has focused on the malig-nant potential of HTT, results show that this tumor has a favorable clinical prognosis. Improving the preoperative diagnosis of HTT can reduce the scope of operation because misdiagnosis before or during surgery may lead to unnecessary total thyroidectomy. This study re-viewed the pathology, diagnosis, therapy, and prognosis of HTT.

Objective To improve the ultrasonic differential diagnosis of thyroid lump through analyzing pathological and ultrasonic features of papillary thyroid carcinoma. Methods Records of 173 cases papillary thyroid carcinoma were analyzed retrospectively in terms of preoperative ultrasonic manifestation, lesion size, echo,boundary, calcification, blood supply, lymph node metastasis and accompanying diseases etc. Results The avthe 173 papillary thyroid carcinoma cases, the number of cancer nodule was 203. There was no statistical difference between papillary thyroid carcinoma lesion and papillary thyroid microcarcinoma lesion in terms of low echo and ill-defined borders (P > 0. 05). The former is higher than the latter in blood flow speed, microcalcification rate, and preoperative ultrasonic diagnosis rate (P <0. 01, P <0. 05, P <0. 01 respectively). The mulifocality rate for the 173 cases with papillary thyroid carcinoma is 33.53% (58/173). There was no statistical difference between papillary thyroid carcinoma and papillary thyroid microcarcinoma in cancer lesion(P >0. 05), while the former has a higher rate of lymph node metastasis than the latter(P <0. 01). Preoperative diagnosis rate is higher in papillary thyroid microcarcinoma cases without other thyroid diseases than in cases with other thyroid diseases (P < 0. 05). No statistical difference of preoperative diagnosis rate was seen between papillary thyroid carcinoma patients with other thyroid diseases and those without other thyroid diseases (P > 0. 05). Conclusions The overall evaluation of thyroid nodule diameter, boundary, echo, small calcification, lymph node metastasis, blood supply, accompanying diseases and so on can improve diagnosis of primary papillary thyroid carcinoma.
