ObjectiveTo discuss clinical significance of total endoscopic thyroidectomy (TET) via chest-breast approach. MethodsThe clinical data of 890 patients with thyroid diseases from September 2008 to September 2015 in this hospital were analyzed retrospectively. These patients were divided into TET group (received TET, n=420) and traditional group (received traditional thyroidectomy, n=470). The data of operation and postoperative recovery were compared between these two groups. ResultsThere was no significant difference between the TET group and the traditional group in the operation time [(73.571 4±28.533 9) min versus (70.212 8±27.199 8) min, t=1.80, P=0.072 7], bleeding volume [(30.714 3±14.225 1) mL versus (29.106 4±13.559 1) mL, t=1.73, P=0.084 8], postoperative drainage [(60.000 0±27.287 9) mL versus (56.595 7±27.803 5) mL, t=1.84, P=0.066 2], postoperative hospitalization time [(5.333 3±1.085 1) d versus (5.446 8± 1.089 0) d, t=1.55, P=0.120 4], postoperative 24 h pain score [(5.333 3±2.308 7) points versus (5.404 3±2.182 1) points, t=0.47, P=0.637 8] and postoperative injury rate of recurrent laryngeal nerve [0.714 2% (3/420) versus 0.851 1% (4/470), x2=0.053 2, P=0.817 6] and hypoparathyroidism rate [0.476 2% (2/420) versus 0.851 1% (4/470), x2=0.465 5, P=0.495 1]. The score of aesthetic effect of incision on day 7 after operation in the TET group was significantly higher than that in the traditional group [(7.809 5±1.296 9) points versus (3.361 7±1.391 8) points, t=49.14, P < 0.000 1]. ConclusionTET is safe and effective, and could improve cosmetic effect for patients with thyroid diseases.
ObjectiveTo summarize the advancement of transoral endoscopic thyroidectomy vestibular approach (TOETVA).MethodThe relevant literatures about comparative study btween TEOTVA and other thyroidectomy were retrospectively analyzed and summarized.ResultsCompared with the conventional open thyroidectomy or other endoscopic thyroidectomy, even though TOETVA requires a longer operative time, it provides similar surgical outcomes and no scar on the body.ConclusionTOETVA is a safe and effective procedure with excellent cosmetic results for patients with thyroid disease.
ObjectiveTo systematically evaluate the reliability and stability of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and conventional open thyroidectomy (COT) in the treatment of differentiated thyroid cancer.MethodsThe clinical studies of TOETVA and COT in the treatment of differentiated thyroid cancer were retrieved from major databases including PubMed, Embase, Cochrane Library, Wanfang, and CNKI by computer. The search date ended on March 1, 2020. Two investigators screened the literatures strictly and extracted the data following the pre-defined inclusion and exclusion criteria, and then used RevMan 5.3 software for meta-analysis.ResultsA total of 7 studies including 1 465 patients were included in this meta-analysis. The results showed: compared with the COT group, the operation time of the TOETVA group was longer [WMD=35.18, P=0.000 1], and the number of lymph node dissections in the central area was larger [WMD=1.42, P=0.000 5]. But the intraoperative blood loss [WMD=–5.32, P=0.39], the length of hospital stay after operation [WMD=0.05, P=0.94], the incidences of transient recurrent laryngeal nerve palsy [OR=0.81, P=0.43], transient hypocalcemia [OR=0.55, P=0.35], permanent hypocalcemia [OR=0.39, P=0.22], permanent recurrent laryngeal nerve palsy [OR=1.34, P=0.73], and hematoma [OR=1.29, P=0.69] were not statistically significant between the two groups.ConclusionsTOETVA has a higher stability. Although the COT has a shorter operation time, the former has a higher central lymph node dissection rate, and there is no scar on the neck after surgery and no significant difference in the incidence of postoperative complications.
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.
