A retrospective comparative study between robotic thyroidectomy through transoral vestibular approach and bilateral breast-axillary approach / 中华外科杂志

Objective: To compare the surgical outcome of robotic thyroidectomy through transoral approach and the bilateral breast-axillary approach. Methods: Retrospective analysis was made on the clinical data of patients who performed transoral robotic thyroidectomy (TORT group) or bilateral breast-axillary approach (BABA group) in the Department of Thyroid and Breast Surgery, the 960th Hospital of People's Liberation Army from July 2020 to May 2022. Both groups received lobectomy with lymph node dissection of the central region. A total of 100 cases were included in the study, including 48 cases in the TORT group and 52 cases in the BABA group. The propensity score matching method was used for 1∶1 matching of patients between the 2 groups, with a match tolerance of 0.03. There were 31 patients in each group successfully matched. In the TORT group, there were 5 males and 26 females, aged (33.2±7.9) years (range: 21 to 53 years). While there were 4 males and 27 females in the BABA group, aged (34.6±9.2) years (range: 19 to 58 years). The t test, Mann-Whitney U test, χ2 test or Fisher exact test were used to compare the clinical efficacy between the two groups. Results: All the patients successfully completed robotic thyroid surgery without conversion to open surgery. Compared with BABA group, the TORT group had longer operation time ((211.3±57.2) minutes vs. (126.2±37.8) minutes, t=6.915, P<0.01), shorter drainage tube retention time ((5.4±1.0) days vs. (6.4±1.2) days, t=-3.544, P=0.001), shorter total hospital stay ((6.6±1.2) days vs. (7.4±1.3) days, t=-2.353, P=0.022), and higher cosmetic score (9.46±0.25 vs. 9.27±0.26, t=2.925, P=0.005). There was no significant difference between the two groups in the number of lymph nodes dissection, metastasis in the central compartment, and the incidence of postoperative complications (all P>0.05). Conclusions: Compared with the bilateral breast-axillary approach, the transoral vestibular approach of robotic thyroidectomy is also safe and effective. It shows similar surgical results to the bilateral breast-axillary approach in strictly selected patients, but the postoperative recovery speed is much faster, and the hospital stay is shorter. Transoral robotic thyroidectomy is a more recommended surgical method for patients with high aesthetic demand.

Evidence mapping of clinical research on 28 Chinese patent medicines for tension-type headache / 中国中药杂志

In this study, the evidence mapping methodology was used to systematically retrieve and sort out the clinical research evidence of Chinese patent medicines in the treatment of tension-type headache(TTH), and to understand the distribution of evidence in this field and the basis and quality of evidence. Chinese and English articles on the 28 Chinese patent medicines for TTH, which were recorded in National Essential Medicines List(2018), Medicine Catalogue for National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance(2020), and Chinese Pharmacopoeia(2020), were retrieved from China National Knowledge Infrastructure(CNKI), Wanfang, VIP, China Biology Medicine disc(CBMdisc), PubMed, EMbase, and Cochrane Library from the establishment to June 2021, followed by descriptive analysis. Then, tables and bubble charts were plotted to analyze the distribution characteristics of evidence. A total of 129 eligible articles were yielded: 126 randomized/non-randomized controlled trials, and 3 systematic reviews. The functions, indications, and composition of the 28 medicines, as well as the proportion of related articles, publication trends, intervention measures, and outcome indicators were compared and analyzed. The results showed that the 28 Chinese patent medicines, composed of 128 Chinese medicinals, can be classified into six categories in terms of function: reinforcing healthy Qi, tranquilizing mind, dispelling stasis, regulating Qi, treating wind, and resuscitating. There are ongoing efforts to study the treatment of TTH with Chinese patent medicine in China, despite of little evidence. The clinical positioning of Chinese patent medicine for TTH is not clear, and clinical research fails to highlight the advantages of Chinese medicine. In addition, the outcome indicators have not been standardized and unified, and there is a lack of evidence on the long-term efficacy of Chinese patent medicine for TTH. This study is the first exploratory application of evidence maps to compare the characteristics and clinical research progress of 28 Chinese patent medicines for TTH, which can provide a reference for research on the optimization of Chinese medicine strategies for TTH.

Combined common femoral artery endarterectomy with superficial femoral artery stenting plus Shuxuening Injection infusion for chronic lower extremity ischemia: 3-year results / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the efficacy and safety of combined common femoral artery (CFA) endarterectomy with superficial femoral artery (SFA) stenting plus Shuxuening Injection infusion in patients with complex multifocal arterial steno-obstructive lesions of the lower extremities.</p><p><b>METHODS</b>From March 2006 to March 2011, 104 lower limbs in 96 patients with multilevel peripheral arterial steno-occlusive disease, involving SFA as well as CFA and deep femoral artery (DFA) orifice, were treated by combined surgical with endovascular therapy, such as SFA stenting as an adjunct to CFA endarterectomy and patch angioplasty with the great saphenous vein. Before the end of the operation, 20 mL of Shuxuening Injection was infused through the catheter located in the treated artery. Technical and hemodynamic success, as well as primary and primary-assisted patency, was determined according to the Society for Vascular Surgery Guidelines. During follow-up, clinical status assessment, ankle-brachial index (ABI) test, and duplex Doppler ultrasound were administered every 6 months, and computed tomography angiography or magnetic resonance angiography was performed at 12, 24, and 36 months after discharge.</p><p><b>RESULTS</b>All patients underwent successful combined CFA endarterectomy with SFA stenting treatment. The average ABI after the combination treatment increased from pretreatment of 0.32±0.21 to 0.82±0.24 (P<0.01). No perioperative death and major limb amputations occurred. The mean duration of follow-up for 104 limbs from 96 patients was 1,180 days (range, 196-2,064 days). During follow-up, 5 patients died due to myocardial infarction, cerebral infarction, or pneumonia, and 5 patients were lost to follow-up. There were 21 cases (21.4%) of restenosis, with 15 that occurred in-stent and 6 near the distal end of the stent. A total of 18 (18.3%) reinterventions were performed, including 6 balloon angioplasty, 8 restenting procedures, 2 bypass surgeries, and 2 major limb amputations. The primary patency rates were 92.2%, 76.8%, and 61.3% at 12, 24, and 36 months, respectively, while the primary-assisted patency rates were 94.4%, 83.2%, and 75.6% at 12, 24, and 36 months, respectively.</p><p><b>CONCLUSION</b>The combined CFA endarterectomy with SFA stenting plus Shuxuening Injection infusion appears to offer a safe, less invasive, and effective treatment option to patients with chronic lower extremity ischemia due to complex multifocal peripheral artery disease.</p>
