Background Robotic-assisted techniques are a tremendous revolution in modern surgery, and the advantages and indications were well discussed in different specialties. However, the use of robotic technique in plastic and reconstructive surgery is still very limited, especially in the field of peripheral nerve reconstruction. This study aims to identify current clinical applications for peripheral nerve reconstruction, and to evaluate the advantages and disadvantages to establish potential uses in the future. Methods A review was conducted in the literatures from PubMed focusing on currently published robotic peripheral nerve intervention techniques. Eligible studies included related animal model, cadaveric and human studies. Reviews on robotic microsurgical technique unrelated to peripheral nerve intervention and non-English articles were excluded. The differences of wound assessment and nerve management between robotic-assisted and conventional approach were compared. Results Total 19 studies including preclinical experimental researches and clinical reports were listed and classified into brachial plexus reconstruction, peripheral nerve tumors management, peripheral nerve decompression or repair, peripheral nerve harvesting, and sympathetic trunk reconstruction. There were three animal studies, four cadaveric studies, eight clinical series, and four studies demonstrating clinical, animal, or cadaveric studies simultaneously. In total 53 clinical cases, only 20 (37.7%) cases were successfully approached with minimal invasive and intervened robotically; 17 (32.1%) cases underwent conventional approach and the nerves were intervened robotically; 12 (22.6%) cases converted to open approach but still intervened the nerve by robot; and 4 (7.5%) cases failed to approach robotically and converted to open surgery entirely. Conclusion Robotic-assisted surgery is still in the early stage in peripheral nerve surgery. We believe the use of the robotic system in this field will develop to become popular in the future, especially in the fields that need cooperation with other specialties to provide the solutions for challenging circumstances.
Thoracic sympathectomy to treat palmar hyperhidrosis (PH) has widely been performed.Many patients regret the surgery due to compensatory hyperhidrosis (CH), gustatory hyperhidrosis, arrhythmia, hypertension, gastrointestinal disturbances, and emotional distress. Robotic applications in microsurgery are very limited. We report the technique and long-term patient-reported outcomes of bilateral robot-assisted microsurgical sympathetic trunk reconstruction with a sural nerve graft in an interdisciplinary setting. A 59-year-old female suffered from severe adverse effects after endoscopic thoracic sympathectomy (ETS) for PH 25 years ago. She reported CH over the whole trunk, gustatory hyperhidrosis, excessive dry hands, and emotional distress. An interdisciplinary surgical team performed a bilateral sympathetic trunk reversal reconstruction with an interpositional sural nerve graft per side by a da Vinci ® Robot. The nerve graft was microsurgically coapted using 9-0 sutures end-to-end to the sympathetic trunk stumps and side-to-end to the intercostal nerves T2-T4. At 24, 33 and 42 months, palmar dryness and emotional distress were strongly reduced. A highly specialized interdisciplinary setting may provide a precise, safe, and efficient treatment for ETS sequelae. A clinical study is initiated to validate this new therapy.
Purpose The impact of the coronavirus disease 2019 (COVID-19) outbreak shut down most conferences. To minimalize the influence, virtual meetings sprang up subsequently. International Microsurgery Club (IMC), as one of the largest professionals-only online microsurgery education groups worldwide, began to host regular weekend webinars during the pandemic to fill the knowledge gap. This study aims to discuss how webinars have fundamentally changed the way knowledge is delivered and exchanged. Methods From February 29, 2020 to March 14, 2021, 103 IMC webinars were reviewed and analyzed in detail to determine the use, benefit, and effect. A comparison between webinars hosted by the different societies was made as well. A questionnaire survey focusing on attendees' behavior, attitude, and using habit about webinars was also made. Results As for the 103 IMC webinar events, the peak participants were 112.3 people in average. The members requesting to join IMC abruptly increased during the pandemic, and the group activity increased dramatically. From the questionnaire (n = 68), the satisfaction level was high (8.88 ± 1.18/10). The respondents were most satisfied with the good quality of the speakers (73.5%). Not only hosts our webinar series but IMC also serves as the platform that welcomes webinars from other societies to share their information. In September 2020, International Microsurgery Webinar League was established via the significant webinar hosts, with more than 300 recorded webinar talks connected successfully. Conclusion As the knowledge revolution driven by COVID-19 will continue, IMC will keep playing an essential role in exploring new and emerging opportunities to improve knowledge dissemination worldwide beyond the space-time boundary.
Background Loss of elbow flexion is a common sequela of acute brachial plexus injuries (BPIs). The Mackinnon/Oberlin-II double fascicular transfer (DFT) is a widely used method to restore this function in acute C5–6 or C5–7 injuries. This study attempted to evaluate if this technique can be applied reliably for cases involving C8 and/or T1 injuries. Methods Adult patients with acute BPIs who underwent the Mackinnon/Oberlin-II DFT in our center between 2008 and 2018 were retrospectively identified. Group I (n = 37) included patients with only C5–6 or C5–7 injury, while group II (n = 32) patients presented C5–8 ± T1 injuries. The demographic data, pre- and postoperative neurologic evaluations, electrodiagnostic studies, and grip strength assessment were collected. Results A total of 69 patients met the inclusion criteria. Preoperatively, the patients in group II presented poorer nerve conduction and electromyography in both the median and the ulnar nerves and the supply muscles. The percentage of M3 achievement in both groups was 91.9 versus 87.5% and M4 was 73.0 and 71.9%, respectively, which both were not statically significant but the achievement of group II was slower than the group I, 1 to 2 months slower, respectively. Both groups had 57.57 and 46.0% of the postoperative grip power compared with the healthy side, the result of shoulder abduction was not different (p = 0.480). Conclusion With careful preoperative evaluation, early intervention, appropriate intraoperative functional fascicle selection, and aggressive postoperative rehabilitation, indications for the Mackinnon/Oberlin-II DFT technique can safely include acute C5–8 injuries and even partial T1 acute BPIs.
Background One of the most challenging yet common areas in reconstructive surgery is the closure of defects in the lower leg. Surgeons have can choose from several reconstructive options options for the closure of soft tissue defects of the lower leg, including local and free flaps. The aim of this study was to understand the reconstructive strategy for lower leg defects of different microsurgeons around the world by harnessing the power of social media and online questionnaires. Methods A studied case of a patient with an exposed plate over distal tibial fracture was presented via an online questionnaire distributed on various social media platforms. 369 international microsurgeons replied with their preferred treatment choice. The data were analysed according to geographic area, microsurgical training, seniority, and subspecialty. Results Among all the respondents (n=369), 64% would have opted for a free flap reconstruction, while the remaining 36% would have opted for a local/pedicle flap. In the group that would have opted for a free flap, 63% would reconstruct the defect using a free fasciocutaneous flap, while the remaining 37% would have used a free muscle flap. In the local flap group, 60% would have used a local perforator while 30% would have chosen a conventional local flap. While North American and European microsurgeons had a clear preference towards free flaps, Asian, Middle Eastern, African and South American surgeons were evenly divided between local and free flaps. Conclusion In this study, we provide a current global overview of the reconstructive strategies for a lower limb with skin defect and bone or prosthesis exposure. We hope that this will be able to help global microsurgeons and patients worldwide.
