A prospective, randomized controlled study of the safety and efficacy of gasless bilateral axillo-breast approach (BABA) robotic thyroidectomy

Efficacy and Safety of Robotic Bilateral Axillo-Breast Approach Versus Robotic Gasless Axillary Approach for Thyroidectomy: A Systematic Review and Meta-Analysis

OBJECTIVES

To evaluate the comparative efficacy and safety of robotic thyroidectomy techniques, including the robotic bilateral axillo-breast approach (BABA) and the robotic gasless axillary approach (GAA).

DATA SOURCES

A comprehensive literature search was conducted across 5 major electronic databases (PubMed, Embase, Cochrane Library, Web of Science, and Scopus) to identify relevant studies published until May 2024.

REVIEW METHODS

Analysis was conducted using RevMan 5.4 software with pooled mean and rate ratios calculated with 95% CIs.

RESULTS

A total of 73 studies, comprising 70 eligible for meta-analysis, were included. Compared with robotic GAA, robotic BABA was associated with significantly longer operative time (pooled mean: 64.65 min, 95% CI: 51.77-77.53, P<0.00001), increased hospital stay (pooled mean: 1.24 d, 95% CI: 0.92-1.56, P<0.00001), and higher intraoperative bleeding (pooled mean: 44.90 mL, 95% CI: 26.99-62.81, P<0.00001). While no significant differences were observed in the rates of hypoparathyroidism, recurrent laryngeal nerve palsy, chyle leakage, seroma, hematoma, or infection, the incidence of Horner syndrome was significantly higher in the BABA group (pooled risk ratio: 0.01, 95% CI: 0.00-0.05, P=0.003).

CONCLUSIONS

Robotic BABA was associated with longer operative times, increased hospital stays, and higher intraoperative bleeding compared with Robotic GAA, although both techniques demonstrated comparable safety profiles for most outcomes. The higher incidence of Horner syndrome with BABA should be considered when selecting the optimal surgical approach for thyroidectomy.

Progress in gasless endoscopic thyroidectomy

Gasless endoscopic thyroidectomy obviates the necessity for carbon dioxide insufflation to establish a surgical workspace, thus mitigating the potential complications associated with this practice. This technique presents several benefits, such as the maintenance of neck functionality, minimal scarring, and enhanced visibility of the surgical field, which contribute to its extensive adoption in clinical settings. The objective of this study is to synthesize the current methodologies of gasless endoscopic thyroidectomy and to evaluate the advantages and disadvantages inherent to each technique. It aims to offer theoretical insights to assist surgeons in determining the most suitable approach for gasless endoscopic thyroidectomy in their clinical practice.

Robot-Assisted Latissimus Dorsi Flap Harvest for Partial Breast Reconstruction: Comparison With Endoscopic and Conventional Approaches

BACKGROUND

Latissimus dorsi muscle flaps are widely utilized in breast reconstruction. Several methods have been introduced.

OBJECTIVES

The aim was to compare the outcomes of robot-assisted breast reconstruction with a latissimus dorsi muscle flap following partial mastectomy with the outcomes of conventional and endoscopic-assisted techniques.

METHODS

In this prospective single-institution study, Korean females diagnosed with breast cancer who underwent partial mastectomy and breast reconstruction with a latissimus dorsi flap from March 2020 to December 2021 were included. The outcomes of surgery and patient satisfaction utilizing the conventional, endoscopic-assisted, and robot-assisted techniques were compared.

RESULTS

In total, 57 patients were included in this study, among whom 20 underwent conventional reconstruction, and 17 and 20 patients underwent endoscopic and robotic surgery, respectively. There was no statistically significant difference between the 3 methods in postoperative opioid analgesic dosage (P = .459), hospitalization period (P = .225), or the average total amount of donor site drainage during hospitalization (P = .175). With regard to patient satisfaction after surgery, especially regarding the donor site scar, the conventional method showed a significantly lower score than the other 2 techniques.

CONCLUSIONS

Robot-assisted breast reconstruction with a latissimus dorsi muscle flap after partial mastectomy showed higher patient satisfaction than that for the conventional open method. Because robotic surgery is more convenient than the endoscopic technique, it is potentially a good alternative to conventional open or endoscopic surgery.

Is transoral endoscopic thyroidectomy safe for total thyroidectomy compared to open thyroidectomy? A propensity-score matched cohort study with papillary thyroid carcinoma

BACKGROUND

Transoral endoscopic thyroidectomy via vestibular approach (TOETVA) has become increasingly popular in the treatment of papillary thyroid cancer (PTC). This study aimed to describe the safety and feasibility of total thyroidectomy between the TOETVA and open thyroidectomy (OT) approaches for the treatment of patients with PTC.

METHODS

We retrospectively reviewed 780 consecutive patients suffering from PTC that had undergone total thyroidectomy using TOETVA (n = 107) and OT (n = 673) between April 2016 and December 2021 at our institute. Afterward, a total of 101 matched patients' surgical outcomes were compared using propensity score matching (PSM) analysis.

RESULTS

Before PSM, the patients in the TOETVA group were younger (p < 0.001), had a lower body mass index (p < 0.001) and a greater female population (p < 0.001). After PSM, the TOETVA group was associated with significantly longer operative time (p < 0.001), greater blood loss (p < 0.001), total drainage amount (p < 0.001), higher C-reaction protein level (p < 0.001), better cosmetic satisfaction (p < 0.001) and quality of life (p < 0.001) and lower scar self-consciousness (p < 0.001). There was no statistical difference between the groups in the rate of parathyroid autotransplantation and bilateral lymph node dissection, the positivity of lymph node metastasis, number of dissected lymph nodes and positive lymph nodes, multifocality, postoperative level of blood calcium and parathyroid hormone (PTH), rate of PTH < 15 ng/mL, visual analog scale score, duration of hospital stay, complications, mean thyroid stimulating hormone (TSH)-stimulated Tg level before radioactive iodine, mean Tg level without TSH stimulation, and the proportion of serum Tg level of <1.

CONCLUSION

TOETVA is a safe and feasible technique for better cosmetic effects and similar surgical outcomes compared to conventional open surgery for the studied patients that required total thyroidectomy.

Modern Surgical Techniques of Thyroidectomy and Advances in the Prevention and Treatment of Perioperative Complications

Thyroid cancer is the most common cancer of the endocrine system, and, in recent years, there has been a phenomenon of overdiagnosis followed by subsequent overtreatment. This results in an increasing number of thyroidectomy complications being faced in clinical practice. In this paper, we present the current state of knowledge and the latest findings in the fields of modern surgical techniques, thermal ablation, the identification and assessment of parathyroid function, recurrent laryngeal nerve monitoring and treatment and perioperative bleeding. We reviewed 485 papers, from which we selected 125 papers that are the most relevant. The main merit of this article is its comprehensive view of the subject under discussion-both general, concerning the selection of the appropriate method of surgery, and particular, concerning the selection of the appropriate method of prevention or treatment of selected perioperative complications.

Comparison of the Robotic Bilateral Axillo-Breast Approach and Conventional Open Thyroidectomy in Pediatric Patients: A Retrospective Cohort Study

Background: Operations for pediatric thyroid nodules are more complicated, and usually lead to longer scars, which may impair life quality in the long term. Bilateral axillo-breast approach robotic thyroidectomy (BABA RT) may provide a better alternative to conventional open thyroidectomy (COT) for pediatric thyroid nodules. Our study aimed at comparing the surgical and oncological outcomes of BABA RT and COT in pediatric patients. Methods: The data of 49 pediatric patients who consecutively underwent BABA RT or COT (20:29) between July 1998 and November 2021 in our center were retrospectively analyzed, including demographics, surgery extent, surgical outcomes, pathological characteristics, and oncological outcomes. Results: All BABA RT procedures were completed successfully without conversion to open operation. The BABA RT group consisted of 5 benign and 15 malignant cases, while the COT group consisted of 19 benign and 10 malignant cases. The operation time, drain removal time, and number of lymph nodes harvested by central lymph node dissection or lateral lymph node dissection were equivalent in the BABA RT and COT groups. Notably, the postoperative hospital stay of the BABA RT group was shorter than that of the COT group (8.5 [interquartile ranges (IQRs): 3] vs. 11 [IQR: 8] days, p = 0.008). The aesthetic score of the BABA RT group was much higher than that of the COT group (9 [IQR: 1] vs. 6 [IQR: 1], p < 0.001). There was no significant difference between the BABA RT and COT groups in hypoparathyroidism rate (transient, 5 vs. 4; permanent, 1 vs. 0). There was one case of chyle leakage in the COT group and no other complications in any group, such as recurrent laryngeal nerve injury. With a median follow-up of 101 (IQR: 189) months, one case of local relapse and one case of pulmonary metastasis in the COT group were documented. Conclusion: In the hands of experienced surgeons, robotic BABA thyroidectomy can be a safe and effective option for both benign and malignant thyroid nodules in children, including those with lymph node metastasis. Robotic BABA thyroidectomy can offer a better and faster postoperative course and a much better cosmetic result, which is crucial for pediatric thyroid patients.

Comparison of the Postoperative Outcomes of the Mini-Flap Bilateral Axillo-Breast Approach (BABA) and Conventional BABA Robot-Assisted Thyroidectomy

The bilateral axillo-breast approach (BABA) for robot-assisted thyroidectomy has some advantages over other minimally invasive thyroidectomies. However, some people do not consider this as a minimally invasive thyroidectomy because of the wider surgical skin flap. Thus, we devised mini-flap BABA robot-assisted thyroidectomy and analyzed the postoperative outcomes. The clinical records of 44 patients undergoing BABA robot-assisted thyroidectomy using a conventional flap or mini-flap were evaluated retrospectively. There were no significant group differences in clinicopathological characteristics. The operating and flap making times were shorter in the mini-flap group (206.18 ± 31.09 vs. 178.90 ± 34.43 min, p = 0.009; 38.85 ± 2.73 vs. 32.21 ± 8.62 min, p = 0.003, respectively). The total drainage amount was smaller in the mini-flap group (196.57 ± 81.40 vs. 150.74 ± 40.80 mL, p = 0.027). The numeric rating scale score and number of analgesics were lower at 2 h postoperatively in the mini-flap group (5.52 ± 0.87 vs. 4.57 ± 1.31, p = 0.006; 0.95 ± 0.22 vs. 0.65 ± 0.49, p = 0.012, respectively). There was no significant group difference in immediate oncological outcomes (p = 1.000). Mini-flap BABA robot-assisted thyroidectomy minimized the surgical flap and improved surgical outcomes. Therefore, it is a form of minimally invasive thyroidectomy. However, long-term follow-up of oncological outcomes is needed.

“Elastic Stretch Cavity Building” System in Endoscopic Thyroidectomy of Giant Thyroid Tumors

Objective

To analyze the clinical characteristics of patients with large thyroid tumors underwent endoscopic thyroidectomy using the “elastic stretch cavity builder” system.

Methods

This retrospective case series study included thyroid tumor patients admitted to the Ningbo Medical Center Li Hui li Hospital between September 2017 and November 2021. The self-developed “elastic stretch cavity builder” was used to elastically lift the anterior cervical flap, combined with low-pressure (3 mmHg) high-flow CO2 inflation, and create a working cavity for endoscopic thyroidectomy.

Results

This study included 13 patients for analysis. The endoscopic thyroidectomy duration was 92-170 min (mean, 123 ± 24min). The maximum transverse plane diameter of the glands was 5.0-6.2 cm (mean, 5.3 ± 0.3 cm). The maximum sagittal plane diameter was 6.8-10.0 cm (mean, 7.6 ± 0.9 cm). After the “elastic stretch cavity builder” lifted the cervical flap, the height of the subcutaneous region was increased by 1.3 ± 0.2cm without affecting cervical activity. There was no residual scar in the anterior cervical skin puncture hole. All patients were satisfied with the cosmetic with the cosmetic satisfaction score was 3.4 ± 0.5.

Conclusion

The novel mixed cavity building model established by the “elastic stretch cavity builder” might provide the surgeon with additional longitudinal cervical operating space while improving the stability of the space and saving human effort.

Outcomes of simultaneous laparoscopic, hybrid, and open resection in colorectal cancer with synchronous liver metastases: a propensity score-matched study

We aimed to compare the short- and long-term outcomes of simultaneous laparoscopic, hybrid, and open resection for colorectal cancer and synchronous liver metastases. We retrospectively analyzed the data of 647 patients with simultaneous resection of colorectal cancer and liver metastases between January 2006 and December 2018 at three tertiary referral hospitals. Patient’s baseline characteristics, perioperative outcomes, pathological examination results, liver-specific recurrence rate and survivals were compared between the propensity score-matched groups. Forty-two and 81 patients were selected for the laparoscopic vs. hybrid groups, and 48 and 136 patients for laparoscopic vs. open groups, respectively. The laparoscopic group had fewer wound complications (2.1 vs. 13.2%; p = 0.028) than the open group, and a shorter postoperative hospital stay than the hybrid and open groups (8 vs. 11 days, p < 0.001 for both). The 5-year liver-specific recurrence rates were 38.7% and 46.0% in the laparoscopic and hybrid groups, respectively (p = 0.270), and 34.0% and 37.0% in the laparoscopic and open groups, respectively (p = 0.391). Simultaneous laparoscopic resection for colorectal cancer and liver metastases can be performed safely with significantly enhanced postoperative recovery and comparable long-term outcomes compared to hybrid and open resection.

Open versus laparoscopic liver resection of colorectal metastases: a meta-analysis of matched patient populations

In recent years, the management of colorectal liver metastases (CRLM) has evolved significantly. Laparoscopic liver resection is increasingly being performed, despite a lack of major randomized controlled trial evidence or widespread international consensus. The objective of this review was to compare the short- and long-term outcomes following open and laparoscopic CRLM resection. A systematic review of comparative matched population studies was performed. Evaluated endpoints included surgical outcomes and survival outcomes. Twelve studies were included in this review, reporting on 3095 patients. R0 (negative margins) rates were higher in the laparoscopic CRLM group (89.3% versus 86.9%). In addition, laparoscopic resection was associated with less blood loss (486 mls versus 648 mls, p ≤ 0.0001*) and reduced blood transfusion rates (6.7% vs. 12.2%, OR 2.13, 95% CI 1.08-4.19, p = 0.03*). Major complication rates were higher in the open CRLM group (12.5% vs. 8.1%, OR 1.74, 95% CI 1.30-2.33, p = 0.03*), as was overall hospital length of stay (median 7 versus 5.5 days, p = 0.001*). Perioperative mortality was similar between both groups, and there was no significance in 5-year overall survival for open or laparoscopic CRLM resection groups (58% and 61% respectively). Laparoscopic CRLM resection is associated with less blood loss, lower transfusion rates, major complications, and overall hospital length of stay with comparable oncological outcome.

Robot-assisted adrenalectomy: state of the art

Currently, laparoscopic adrenalectomy is worldwide considered the gold standard technique. Both transperitoneal and retroperitoneal approaches have proved their efficacy with excellent outcomes. Since the introduction of da Vinci System (Intuitive Surgical, Sunnyvale, CA), robotic surgery has made many steps forward gaining progressively more diffusion in the field of general and endocrine surgery. The robotic technique offers advantages to overcome some laparoscopic shortcomings (rigid instruments, loss of 3D vision, unstable camera). Indeed, the robotic system is provided of stereoscopic 3D-magnified vision, additional degree of freedom, tremor-filtering technology and a stable camera. Recently, several case series have demonstrated the feasibility and the safety of robot-assisted adrenalectomy in high-volume centers with outcomes comparable to laparoscopic adrenalectomy. Notwithstanding, the technical advantages of the robotic system have not yet demonstrated significant improvements in terms of outcomes to undermine laparoscopic adrenalectomy. Moreover, robotic adrenalectomy harbor inherits drawbacks, such as longer operative time and elevated costs, that limit its use. In particular, the high cost associated with the use of the robotic system is primarily related to the purchase and the maintenance of the unit, the high instruments cost and the longer operative time. Notably, these aspects make robotic adrenalectomy up to 2.3 times more costly than laparoscopic adrenalectomy. This literature review summarizes the current available studies and provides an overview about the robotic scenario including applicability, technical details and surgical outcomes.
