Effects of laparoscopic and traditional open surgery on the levels of IL-6, TNF-α, and Gal-3 in patients with thyroid cancer

A controlled study of the hygienic technical evaluation of the transaxillary approach for inflation-free single-port lumpectomy versus conventional transcervical anterior open surgery in radical thyroid cancer resection

OBJECTIVE

To evaluate sanitary techniques for radical thyroid cancer surgery via the transaxillary approach without inflation single-port endoscopic surgery (TAWISES) and the conventional open anterior cervical approach (COACAS) in a controlled manner.

METHODS

This work was a retrospective analysis of the clinical data of 60 patients admitted to our hospital for unilateral radical thyroid cancer surgery between 01/2021 and 12/2022. The control group underwent COACAS (30 patients), and the experimental group underwent TAWISES (30 patients). The patients' operative time, intraoperative bleeding volume, 24-h postoperative pain index, drainage tube carrying time, hospitalization duration and complication rate were compared and analyzed. The patients were followed up for 3, 6 and 12 months postoperatively and evaluated based on numbness, muscular tightness, pain and other discomfort in the neck, as well as satisfaction with social adaptation and cosmetic incisions. The recurrence status was assessed for 1 year in both groups of patients. A questionnaire survey was conducted to assess patient acceptance of the two surgical approaches. The economic characteristics (cost-effectiveness and cost-utility) of the different approaches in our region were evaluated comprehensively.

RESULTS

The length of the incision, drainage tube carrying time and hospitalization duration were greater in the experimental group than in the control group (P < 0.05). The differences in complication rate, intraoperative bleeding volume, 24-h postoperative pain index and recurrence rate were not statistically significant between the two groups (P > 0.05). Neck discomfort was greater in the control group, and the difference was statistically significant at the 3-month postoperative follow-up (P < 0.05). The differences at the 6- and 12-month postoperative follow-ups were not statistically significant (P > 0.05). However, mild discomfort was significantly more common in the experimental group (63.33% > 36.67%, 80% > 53.33%, P < 0.05). The experimental group had better social adaptability, greater total medical costs, and better overall patient medical satisfaction than did the control group (P < 0.05). The acceptance of TAWISL was greater than that of COACAS (P < 0.05).

CONCLUSION

Compared with COACLAS, TAWISES is safe and effective and better meets the cosmetic, psychological and social adaptation needs of patients. TAWISES is also more cost effective and can be better utilized for the population in our region, filling the gap in surgical modalities for thyroid cancer in in our region.

Biochemical implications of robotic surgery: a new frontier in the operating room

Robotic surgery represents a milestone in surgical procedures, offering advantages such as less invasive methods, elimination of tremors, scaled motion, and 3D visualization. This in-depth analysis explores the complex biochemical effects of robotic methods. The use of pneumoperitoneum and steep Trendelenburg positioning can decrease pulmonary compliance and splanchnic perfusion while increasing hypercarbia. However, robotic surgery reduces surgical stress and inflammation by minimizing tissue trauma. This contributes to faster recovery but may limit immune function. Robotic procedures also limit ischemia-reperfusion injury and oxidative damage compared to open surgery. They also help preserve native antioxidant defenses and coagulation. In a clinical setting, robotic procedures reduce blood loss, pain, complications, and length of stay compared to traditional procedures. However, risks remain, including device failure, the need for conversion to open surgery and increased costs. On the oncology side, there is still debate about margins, recurrence, and long-term survival. The advent of advanced technologies, such as intraoperative biosensors, localized drug delivery systems, and the incorporation of artificial intelligence, may further improve the efficiency of robotic surgery. However, ethical dilemmas regarding patient consent, privacy, access, and regulation of this disruptive innovation need to be addressed. Overall, this review sheds light on the complex biochemical implications of robotic surgery and highlights areas that require additional mechanistic investigation. It presents a comprehensive approach to responsibly maximize the potential of robotic surgery to improve patient outcomes, integrating technical skill with careful consideration of physiological and ethical issues.

Tumor-associated macrophages as a potential therapeutic target in thyroid cancers

Macrophages are important precursor cell types of the innate immune system and bridge adaptive immune responses through the antigen presentation system. Meanwhile, macrophages constitute substantial portion of the stromal cells in the tumor microenvironment (TME) (referred to as tumor-associated macrophages, or TAMs) and exhibit conflicting roles in the development, invasion, and metastasis of thyroid cancer (TC). Moreover, TAMs play a crucial role to the behavior of TC due to their high degree of infiltration and prognostic relevance. Generally, TAMs can be divided into two subgroups; M1-like TAMs are capable of directly kill tumor cells, and recruiting and activating other immune cells in the early stages of cancer. However, due to changes in the TME, M2-like TAMs gradually increase and promote tumor progression. This review aims to discuss the impact of TAMs on TC, including their role in tumor promotion, gene mutation, and other factors related to the polarization of TAMs. Finally, we will explore the M2-like TAM-centered therapeutic strategies, including chemotherapy, clinical trials, and combinatorial immunotherapy.

Comparison of the Effects of Dexmedetomidine and Lidocaine on Stress Response and Postoperative Delirium of Older Patients Undergoing Thoracoscopic Surgery: A Randomized Controlled Trial

Purpose

We investigated the effects of intraoperative intravenous lidocaine or dexmedetomidine infusion on inflammatory factors and cognitive function in patients undergoing thoracoscopic surgery.

Patients and Methods

Patients aged >65 years undergoing elective thoracoscopic lobectomy or segmentectomy were randomly grouped as dexmedetomidine group (group D), lidocaine group (group L), and control group (group C). The plasma cortisol, interleukin-6, and tumor necrosis factor-α concentrations were measured before anesthesia (T0) and immediately (T1), 24 h (T2), and 48 h postoperatively (T3). Postoperative delirium (POD) was assessed by 3D-CAM on days 2 and 7.

Results

The cortisol concentrations decreased for all groups at T1 from T0 although they were significantly higher at T2. Group L had significantly lower interleukin-6 concentrations at T1 and T2 than the other groups (P<0.05). The interleukin-6 concentrations were significantly higher at T1, T2, and T3 than at T0 for all the groups, significantly lower for groups D and L than for group C at T1 and T2 (P<0.05), and significantly lower for group L than for group D at T2 (P<0.05). The tumor necrosis factor-α concentrations were significantly higher at T1, T2, and T3 than at T0 for all the groups and significantly lower for groups D and L than for group C at T1 and T2 (P<0.05), although they were not statistically significantly different for groups D and L. There were no statistically significant differences in the postoperative incidence of POD between the three groups on days 2 and day 7.

Conclusion

Intraoperative continuous intravenous lidocaine or dexmedetomidine infusion reduced surgical stress and inflammatory responses. The inhibitory effect of lidocaine on surgical stress remained significant for up to 24 h postoperatively without affecting patient awakening. However, the administration of either drug failed to prevent postoperative POD.

Advantages of Small Incision Surgery in Thyroid Tumors

Objective

Thyroid tumor is a common thyroid disease, and the incidence of complications after traditional thyroid surgery is high, which seriously affects the prognosis of patients. With the development of minimally invasive techniques, small incision surgery has a positive impact on changing the traditional thyroid surgery treatment. However, the gap between small incision surgery and traditional thyroid surgery is unclear, so this meta-analysis was used to evaluate its application value.

Methods

Searching English biomedical databases, including PubMed and Science Network and Chinese major biomedical databases, including CNKI, Wanfang, and Weipu. The keywords of the searched articles are as follows: small incision surgery, traditional thyroid surgery, thyroid tumor treatment, clinical efficacy of thyroid tumor, and surgical treatment, and these keywords are searched individually or in combination to track relevant systematic reviews and literature meta-analysis, and conduct other studies. The retrieval period is from the establishment of the database to January 2022. After extracting the article data, the patients were divided into small incision surgery group and traditional thyroid surgery group due to different intervention methods. The Cochrane risk of bias tool was used to assess the quality of the included literature, and RevMan 5.30 was used for meta-analysis.

Results

A total of 9 articles met the inclusion criteria. There were 369 patients with small incision surgery and 364 patients with traditional thyroid surgery. Compared with traditional thyroid surgery, patients treated with small incision surgery had significant short hospitalization time (MD −2.72, 95% CI (−3.32, −2.12)), less amount of bleeding (MD −15.52, 95% CI (−20.40, −10.65)), short incision length (MD −12.73, 95% CI (−16.29, −9.17)), lower VAS score (MD −2.58, 95% CI (−4.08, −1.08)), and less complications (RR 0.30, 95% CI (0.21, 0.44)).

Conclusion

Compared with traditional thyroid surgery, the results show that small incision surgery can shorten the hospital stay of patients with thyroid tumor, reduce the length of incision, reduce the amount of bleeding and the occurrence of complications, reduce postoperative pain, and have a positive effect on postoperative survival of patients.
