Methods The transection of the cervical muscles at sternal end and flip fixed in 53 cases was observation group， 44 cases of the neck white line incision thyroid surgery completed for the control group. The completion of the surgery by the same group of physicians. The operative time， operation field of exposing effect， amount of bleeding in operation， postoperative complications， and postoperative drainage volume were compared between two groups. Results There was no statistically differences of sex， age， disease composition， and tumor size between two groups （P＞0.05）. Operative time， amount of bleeding， and postoperative drainage volume in observation group were shorter （less） than that in control group （P＜0.01）. The postoperative complication rate in observation group was lower than that in control group（P=0.04）. Surgical field exposure in observation group was better than that in control group （P＜0.01）. Conclusions The huge bilateral thyroid surgery with the sternal end approach is feasible and simple. The operation field exposure is better than the white line neck incision， complications after operation is less. It is worthy of clinical application.
ObjectiveTo investigate the effect of surgery and influence of posttreatment with non-standardized and standardized operation by reviewing and analyzing the sporadic medullary thyroid carcinoma operation cases. MethodsThe clinical data of 26 patients with sporadic medullary thyroid carcinoma treated by surgery from January 2000 to March 2013 in this hospital were analyzed retrospectively.These patients were divided into non-standardized operation group and standardized operation group (total thyroidectomy with lymph node dissection) according to the operation models.The biochemical cure rate, the complication rates of recurrent laryngeal nerve injury and hypopara-thyroidism of these two groups were investigated and compared. ResultsThe 1-year biochemical cure rate had no statistical difference between the non-standardized operation group and standardized operation group (84.21% versus 100%, χ2=1.249 4, P > 0.05), the 1-year recurrence rate was 15.79% and 0, respectively.The 5-year biochemical cure rate of the standardized operation group was significantly higher than that of the non-standardized operation group (100% versus 16.67%, χ2=4.444 4, P < 0.05).The 5-year recurrence rate was 0 and 83.33%, respectively.However, there was no obvious difference between the two groups on the injury rate of recurrent laryngeal nerve (χ2=0.070 8, P > 0.05), as well as the rate of hypoparathyroidism (χ2=2.722 7, P > 0.05). ConclusionsCompared with the non-standardized model, the standardized operation model (total thyroidectomy with lymph node dissection) shows a higher cure rate and a lower recurrent rate, and it does not increase the complication rates of hypoparathyroidism and recurrent laryngeal nerve injury
Objective To analyze clinical features of reoperation patients with differentiated thyroid cancer, and to explore reason, surgical pattern and therapeutic effectiveness of reoperation. Method The clinical data of 80 patients with differentiated thyroid cancer underwent reoperation from January 2012 to June 2016 in Peking Union Medical College Hospital were analyzed retrospectively. Results ① Eighty (5.37%) patients with differentiated thyroid cancer underwent reoperation were identified from a total of 1 491 patients with thyroid cancer in our treatment team. Twenty-seven cases were males, 53 cases were females. The male to female ratio was 1∶1.96. The age was (44±13) years with a range from 14 to 66 years. The median time between reoperation and the first operation was 16.8 months with a range from 8 days to 17 years. ② Thirteen cases underwent reoperation because of uncertain frozen sections, and the reoperation style was residual lobectomy and selective lymph node dissection. Sixty-seven cases underwent reoperation because of local recurrence or metastasis, 15 of them accepted residual lobectomy and selective lymph node dissection while the other 52 accepted selective lymph node dissection. ③ The rate of residual in thyroid cancer confirmed by postoperative pathology was 18.8% (15/80). The rate of cervical lymph node metastasis was 63.8% (51/80). The temporary laryngeal recurrent nerve injury occured in 6 cases, the temporary hypocalcemia occured in 9 cases, and the lymphorrhagia occured in 2 cases. ④ The hospitalization time was (6.50±0.97) d with a range from 3 to10 d, the time of drainage tube remove was (2.41 ±0.95) d with a range from 2 to 7 d. Seventy-three cases were followed up from 3 to 58 months with (32±18) months, 4 of them underwent operation once again because of local recurrence, no distant metastasis or death happened. ⑤ The proportion of male patients in reoperation patients was significantly higher than that of the first operation patients (P<0.05). The proportion of patients aged <45 years, the average hospitalization time, the average time of drainage tube remove, and the postoperative complications rate had no significant differences between the patients with the first operation and the patients with reoperation (P>0.05). Conclusions For reoperation patients, proportion of male patients is higher. Reoperation is proper treatment for patients with residual lobe or local recurrence or metastasis for differentiated thyroid cancer. Serious complications could be avoided by suitable surgical pattern and careful dissection during operation. Residual lobectomy and selective lymph node dissection are suggested for reoperation.
Objective To summarize research status of correlation of chronic lymphocytic thyroiditis (CLT) and papillary thyroid carcinoma (PTC), in order to provide a basis for early diagnosis, prognosis, and prevention of PTC. Method The literatures about the recent studies of the correlation of the CLT and PTC were reviewed according to the results searched from PubMed database, SpringerLink database, Web of Science database, Wanfang database, CNKI database, and VIP database. Results The most of patients with CLT combined with PTC are young women, the characteristics are multifocal and occult, the prognosis is good. Its genesis might be related to the ionizing radiation, iodine intake, endocrine disorders, immune disorders, molecular biology, and other factors. But there are still different controversies about its specific pathogenesis and surgical treatment. Conclusions CLT is closely related to PTC. However, relationship between CLT combined with PTC and changing regularity of molecular biology, pathogenesis, or prognosis needs further to be studied and followed-up for a longer-term.
Objective To analyze clinical and pathological features of patients with papillary thyroid carcinoma (PTC) with coexistent chronic lymphocytic thyroiditis (CLT). Methods The clinicopathologic data of 756 cases of PTC were collected from January 2014 to January 2017 in the First Affiliated Hospital, Xinjiang Medical University were collected. The patients were designed to observational group (PTC with coexistent CLT, n=194) and control group (simple PTC, n=562) according to whether CLT was diagnosed by pathology, then the clinical data, ultrasonic features, thyroid function, and pathological features in these two groups were compared. Results The proportion of the female patients, the proportions of theserum thyroid stimulating hormone and thyroid autoimmune antibodies (thyroglobulin antibody and thyroid peroxidase antibody), and the proportion of multifocal carcinoma in the observational group were significantly higher than those in the control group (P<0.05). There were no significant differences in the preoperative ultrasound, tumor diameter, thyroid capsule invasion, central lymph node metastasis, and TNM stage in these two groups (P>0.05). The results of the multivariate analysis showed that the female, serum thyroid autoimmune antibodies, and the multifocal carcinoma were the independent predictive factors of PTC with CLT (P<0.05). Conclusions There might be a certain correlation between PTC and CLT, PTC with coexistent CLT is more common in female patient and with multifocal carcinoma. With coexistent CLT does not increase invasion of PTC. This may be associated with limit of CLT to development of PTC nodules. It is speculated that CLT may be a protective factor of PTC.
Objective The aim of this study is to review the molecular landscape of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). Method The relevant literatures about molecular profiling of NIFTP were retrospectively analyzed and summarized. Results The most common mutation in NIFTP was rat sarcoma viral oncogene homolog (RAS) mutation. B-type RAF (BRAFK601E) mutation, PPARG fusion, and THADA fusion also could be seen. There was usually no BRAFV600E mutation. miRNAs also were found to be differentially expressed in NIFTP. Conclusion The molecular profiling of NIFTP may become a new molecular marker for the diagnosis of NIFTP.
ObjectiveTo summarize the clinical manifestations, pathogenesis, diagnosis and treatment of multiple endocrine neoplasia type 1 (MEN-1) so as to improve the understanding of MEN-1.MethodThe clinical data of 1 case of MEN-1 with new mutated gene in the Yantai Yuhuangding Hospital of Medical College of Qingdao University (our hospital) were analyzed retrospectively.ResultsThe patient was a 73-year-old woman, who was admitted to our hospital because of “abdominal pain, diarrhea” for 4 d. After discussion by a multidisciplinary team, MRI of pancreatic, adrenal and pituitary, and endoscopy examinations were performed to further identify the cause of diarrhea. Meanwhile, MEN-1 gene was detected in the peripheral blood of the patient and her relatives, and the result showed that the proband and his daughter had a cytosine deletion at c.1401 in exon 10 of MEN-1 gene, which resulted in frame shift mutation of p.e468r fs, it was confirmed as MEN-1. After 5 d of conservative treatment of the disease, the patient’s family requested discharge and the patient died half a month after discharge.ConclusionsMEN-1 is a rare autosomal dominant inheritable disease, with diverse clinical manifestations and easy misdiagnosis. Therefore, it is necessary to be alert to abnormal indicators in the glands associated with MEN-1, so as to achieve early diagnosis and treatment.
Thyroid disease is more common in young women. Traditional surgical scars may affect the appearance of patients and cannot fully meet the cosmetic needs of patients. With the advancement of surgical techniques, endoscopic thyroid surgery has developed rapidly. Trans oral endoscopic thyroidectomy vestibular approach is feasible and safe to achieve no scar on the body surface, but there are some unavoidable limitations, such as postoperative numbness and discomfort in the center of the chin region. As a new approach to thyroid surgery, trans oral endoscopic thyroidectomy submental access has the same advantages as the trans oral vestibular approach from top to bottom, and can reliably and thoroughly dissect lymph nodes in the central area (especially area Ⅶ), allowing larger specimens to be taken out and expands the indications for surgery, minimizes flap detachment, and avoids jaw pain and numbness. Trans oral endoscopic thyroidectomy submental access is an innovation in the concept of thyroid surgery, which achieves minimally invasive and aesthetic results on the premise of ensuring the quality of the surgery and curing the disease. We reviewed the history, advantages and disadvantages of trans oral endoscopic thyroidectomy submental access.
ObjectiveTo compare the effect of robotic thyroidectomy and endoscopic thyroidectomy on the voice function. MethodsThe clinical data of 181 patients with differentiated thyroid cancer admitted to Panzhihua Central Hospital of Sichuan Province from March 2022 to June 2023 were analyzed retrospectively. According to the operative mode, this patients were divided into two groups: the endoscope group (n=91) and the robot group (n=90). The subjective and objective acoustic indicators were compared between the two groups at 1 day before operation and 1 week, 1 month and 3 months after operation. ResultsThere were no significant difference in voice handicap index (VHI)-10 scores between the two groups at different time points before and after operation (P>0.05). There were no significant difference of VHI-10 scores between preoperative and different postoperative phases in the robot group (P>0.05). The score of VHI-10 at different postoperative phases in the endoscopic group was higher than that at 1 d before operation (P<0.05). The incidence of voice dysfunction (VHI-10 score ≥8) was 1.1% (1/90), 1.1% (1/90) and 0.0% (0/90) in the robot group, 1.1% (1/91) , 2.2% (2/91) and 0.0% (0/91) in the endoscope group at 1 week, 1 month and 3 months after operation respectively, there were no significant difference between the two groups (P>0.05). The fundamental frequency of patients in the endoscopic group was lower than that at 1 d before operation (P<0.05), and there was no significant difference between each phase after operation and at 1 d before operation of fundamental frequency in the robot group (P>0.05). The fundamental frequency of patients in the endoscopic group was lower than that in the robot group at 1 week after operation (P<0.05). The maximum phonation time of each phase after operation in the robot group was not significantly different from that at 1 d before operation (P>0.05). The maximum phonation time of 1 week after operation in the endoscopic group was shorter than that at 1 d before operation (P<0.05) and also shorter than that in the robot group (P<0.05). There were no significant difference in fundamental frequency perturbation, amplitude perturbation, harmonic noise ratio and voice disorder severity index between the two groups at different phases before and after operation (P>0.05). ConclusionCompared with endoscopic thyroidectomy, the voice function of robotic thyroidectomy via bilateral axillary breast approach is better.
