    目的:本研究旨在探讨超声造影(CEUS)能否用于揭示大鼠模型浅表皮瓣术后早期的血供状况。
    方法:在同一只大鼠的左右背部分别制备一个活瓣和一个缺血随机型皮瓣,数量为40。术后12h和7天内进行CEUS检查,并且两个皮瓣的基部和末端的微血管血容量(BV)的定量测量使用声学强度与健康皮肤的比率来表示。
    结果:术后12小时内,缺血末端的BV值小于缺血基础和存活末端的BV值(p<0.001),而缺血碱基和活基之间或活基和活端之间没有差异。手术后7天提供相同的结果。
    结论:可以通过CEUS定量评估该大鼠模型中诸如随机模式皮瓣的浅表组织的微循环。它能灵敏、准确地揭示术后早期组织灌注的客观状态。
    OBJECTIVE: This study aims to investigate whether contrast-enhanced ultrasound (CEUS) could be used to reveal the status of blood supply of the superficial flap of rat model in the early postoperative stage.
    METHODS: One viable and one ischemic random-pattern flap were prepared on the left and right back of the same rat respectively with a number of 40. CEUS examinations were applied within 12 h and 7 days postoperatively, and the quantitative measurements of microvascular blood volume (BV) of the base and the end of both flaps were expressed using acoustic intensity as a ratio to that of the healthy skin.
    RESULTS: Within 12 h post operation, there was a smaller BV value of the ischemic ends than that of both the ischemic bases and viable ends (p < 0.001), while no difference was indicated between ischemic bases and viable bases or between viable bases and viable ends. The same result was provided 7 days post operation.
    CONCLUSIONS: Microcirculation of superficial tissues such as random-pattern flaps in this rat model can be assessed quantitatively by CEUS. It could sensitively and accurately reveal the objective status of tissue perfusion in the early postoperative stage.

    机器人手术已广泛应用于胃癌的外科治疗,包括近端胃切除术.单端口机器人系统在机器人手术中越来越受欢迎,但尚无关于其在右侧重叠和单瓣瓣膜成形术(RPG-ROSF)的机器人近端胃切除术中应用的报道。这里,我们报道了一名51岁男性患者使用新型单端口机器人系统的RPG-ROSF,该患者患有胃镜检查发现的早期胃食管癌.机器人安装花了90分钟,解剖143分钟,消化道重建161min。手术期间和术后均无并发症。患者术后8天出院。腺癌的病理分期为pT1aN0M0。这项初步研究证明了新型单端口机器人在RPG-ROSF中的可行性和安全性。
    Robotic surgery has been widely used in surgical gastric cancer treatments, including proximal gastrectomy. Single-port robotic system is gaining more popularity in robotic surgery, but there has been no report on its application in robotic proximal gastrectomy with right-sided overlap and single-flap valvuloplasty (RPG-ROSF). Here, we report an RPG-ROSF using a novel single-port robotic system in a 51-year-old male patient with an early-stage gastroesophageal cancer detected by gastroscopy. It took 90 min for robotic setup, 143 min for dissection, and 161 min for digestive tract reconstruction. There was no complication during and after the surgery. The patient was discharged in 8 days postsurgery. The pathological staging of the adenocarcinoma was pT1aN0M0. This preliminary study demonstrated the feasibility and safety of a novel single-port robot in RPG-ROSF.

    纯血管化骨膜移植已被证明在具有生物复杂性骨不连的儿童中实现快速骨愈合方面非常有效。当需要大型骨膜瓣时,通常需要进行胫骨和腓骨骨膜移植。我们报告了使用血管化的股骨肌肉骨膜移植物(VFMPG)治疗一名6岁男孩先天性胫骨假关节的胫骨远端截骨术不愈合。移植物由一个9厘米的肌肉骨膜皮瓣(弹性回缩50%后)组成,该皮瓣结合了由旋股外侧血管的降支滋养的中间肌和骨干股骨膜。前胸被用作受体血管。术后10周愈合。患者在没有矫形器的情况下恢复步态和运动活动。术后17个月无供体或受体部位并发症发生。使用VFMPG可能是目前用于复杂儿科不愈合的其他游离或大型血管化骨膜瓣的替代方法。
    Pure vascularized periosteal transplants have been shown to be extremely effective at achieving rapid bone healing in children with biologically complex non-union. Free tibial and fibular periosteal transplants are generally indicated when large periosteal flaps are necessary. We report using a vascularized femoral myo-periosteal graft (VFMPG) to treat distal tibial osteotomy non-union in a six-year-old boy with congenital pseudarthrosis of the tibia. The graft consisted of a 9 cm myo-periosteal flap (after 50% of elastic retraction) that incorporated the vastus intermedius muscle and diaphyseal femoral periosteum nourished by the descending branch of the lateral circumflex femoral vessels. Plantaris medialis was used as a recipient vessel. Healing occurred 10 weeks after surgery. The patient resumed gait and sports activity without orthosis. No donor or recipient site complications occurred 17 months after surgery. Employing a VFMPG might be an alternative to other free or large vascularized periosteal flaps currently in use for complex pediatric non-unions.

    背景:包皮环切后坏死后阴茎的灾难性损失是一种罕见且毁灭性的并发症。治疗选择有限,这个过程非常具有挑战性。这项研究旨在报告我们的联合治疗方法在包皮环切术后1年因进行性坏死而出现阴茎完全丧失的6岁患者中的成功应用。
    结果:阴茎脱套后,进行了阴茎近端活动和分离以及体部重塑。阴茎轴用隧道状的复合腹股沟前外侧皮瓣覆盖。使用左颊粘膜移植物进行眼球成形术,随后是10次高压氧治疗。术后1.5个月,由于轻微的排尿困难,进行了一次尿道扩张。术后10个月,患者的排尿功能良好,没有其他投诉。患者对结果表示高度满意,仍在密切随访中。
    结论:严重并发症如坏死和阴茎全失的标准治疗方法尚未建立。虽然阴囊皮瓣是一种简单的技术,由于阴囊坏死后的纤维化和潜在的毛发生长风险,我们的病例并不优选.所开发的方法可能是其他技术的有效替代方法。
    BACKGROUND: Catastrophic loss of the penis following post-circumcision necrosis is a rare and devastating complication. Treatment options are limited, and the process is highly challenging. This study aims to report the successful application of our combined treatment approach for a 6-year-old patient who experienced total penile loss due to progressive necrosis 1 year after circumcision.
    RESULTS: Following penile degloving, proximal penile mobilisation and separation and reshaping of the corpora were performed. The penile shaft was covered with a tunnelled composite anterior-lateral inguinal skin flap. Glanuloplasty was performed using a left buccal mucosal graft, followed by 10 sessions of hyperbaric oxygen therapy. At 1.5 months postoperatively, urethral dilation was performed once because of minor voiding difficulties. At 10 months postoperatively, the patient had excellent voiding function and no additional complaints. The patient expressed high satisfaction with the outcome and is still under close follow up.
    CONCLUSIONS: A standard treatment for serious complications such as necrosis and total penile loss has not been established yet. Although scrotal skin flap is a straightforward technique, it was not preferred in our case because of fibrosis following scrotal necrosis and potential risk of hair growth. The developed approach could be an effective alternative to other techniques.

    背景:体重指数(BMI)升高是已知的围手术期并发症的危险因素,例如伤口愈合延迟和感染。然而,在了解BMI升高如何影响创伤后下肢(LE)微血管重建后的结局方面存在差距.
    方法:在2007年至2022年期间,在1级创伤中心对接受创伤后微血管LE重建的患者进行了回顾性回顾。人口统计,皮瓣/伤口细节,并发症,并记录结果。将患者分为BMI疾病控制中心类别。
    结果:共纳入398例患者,平均BMI为28.2±5.8。将近一半(45%)的LE缺损位于腿的远端三分之一,中间三分之一的27.5%,近三分之一为34.4%。大多数重建使用含肌肉的皮瓣(74.4%),而筋膜皮瓣(16.8%)。手术方法包括游离皮瓣(47.6%)和局部皮瓣(52.5%)。III类肥胖患者比非肥胖患者更有可能无法行走(OR:4.10,95%CI1.10-15.2,p=0.035)。在最后的后续行动中,30.1%的III类肥胖患者是卧床,需要轮椅(42.3%)或辅助装置(26.9%)。基于肥胖状态的并发症发生率无显著差异(0.704)。整个队列的平均随访时间为5.8年。
    结论:BMI对于LE重建中的患者护理和手术决策至关重要。需要进一步的研究来优化BMI较高患者的预后,从而有可能减少术后并发症的负担并提高患者的整体康复。
    BACKGROUND: Elevated body mass index (BMI) is a known perioperative risk factor for complications such as delayed wound healing and infection. However, there is a gap in understanding how elevated BMI impacts outcomes after posttraumatic lower extremity (LE) microvascular reconstruction.
    METHODS: A retrospective review was performed at a level 1 trauma center between 2007 and 2022 of patients who underwent posttraumatic microvascular LE reconstruction. Demographics, flap/wound details, complications, and outcomes were recorded. Patients were stratified into BMI Center for Disease Control categories.
    RESULTS: A total of 398 patients were included with an average BMI of 28.2 ± 5.8. Nearly half (45%) of LE defects were located in the distal third of the leg, 27.5% in the middle third, and 34.4% in the proximal third. Most reconstructions utilized muscle-containing flaps (74.4%) compared with fasciocutaneous flaps (16.8%). Surgical approaches included free flaps (47.6%) and local flaps (52.5%). Class III obese patients were significantly more likely to be nonambulatory than nonobese patients (OR: 4.10, 95% CI 1.10-15.2, p = 0.035). At final follow-up, 30.1% of patients with Class III obesity were ambulatory, requiring either wheelchairs (42.3%) or assistance devices (26.9%). There were no significant differences in complication rates based on obesity status (0.704). The average follow-up time for the entire cohort was 5.8 years.
    CONCLUSIONS: BMI is critical for patient care and surgical decision-making in LE reconstruction. Further research is warranted to optimize outcomes for higher BMI patients, thereby potentially reducing the burden of postoperative complications and enhancing overall patient recovery.

    背景:牙槽骨丢失经常发生在拔牙后的前六个月。各种研究已经提出了不同的方法来尽可能地减少拔牙后牙槽脊的萎缩。提取后用生物材料填充牙槽可以减少牙槽的吸收。我们比较了拔牙部位内侧和远端的牙槽突高度,并在应用HA/β-TCP或与血液混合的合成共聚物聚乙醇酸-聚乳酸PLGA后计算了吸收速率,以防止牙槽吸收立即和拔牙后。
    方法:本研究是对双侧下颌阻生第三磨牙的24个拔牙窝进行的,垂直,完全覆盖,薄薄的骨层。拔牙后立即将HA/β-TCP插入12个牙槽中,将合成聚合物PLGA插入12个牙槽中。所有插座都用全厚度信封盖完全覆盖。提取后随访一年,使用X光片和支架进行垂直牙槽脊测量。
    结果:HA/β-TCP和PLGA组的平均吸收率分别为±1.23mm和±0.1mm,分别。9个月后,观察到HA/β-TCP的牙槽骨高度降低,减少显示轻微减少到0.93毫米,而PLGA组9个月后该比率为0.04mm。此外,骨高度在三个月后得以维持,表明HA/β-TCP移植物在保留牙槽骨(1.04mm)方面具有良好的性能,而PLGA的此速率为(0.04mm)。
    结论:PLGA移植物在拔牙后保留牙槽方面表现出足够的安全性和有效性。然而,HA/β-TCP在增强位点比PLGA引起更大的再吸收,临床医生在制定治疗计划时应考虑的问题。
    BACKGROUND: Alveolar Bone loss occurs frequently during the first six months after tooth extraction. Various studies have proposed different methods to reduce as much as possible the atrophy of the alveolar ridge after tooth extraction. Filling the socket with biomaterials after extraction can reduce the resorption of the alveolar ridge. We compared the height of the alveolar process at the mesial and distal aspects of the extraction site and the resorption rate was calculated after the application of HA/β-TCP or synthetic co-polymer polyglycolic - polylactic acid PLGA mixed with blood to prevent socket resorption immediately and after tooth extraction.
    METHODS: The study was conducted on 24 extraction sockets of impacted mandibular third molars bilaterally, vertically, and completely covered, with a thin bony layer. HA/β-TCP was inserted into 12 of the dental sockets immediately after extraction, and the synthetic polymer PLGA was inserted into 12 of the dental sockets. All sockets were covered completely with a full-thickness envelope flap. Follow-up was performed for one year after extraction, using radiographs and stents for the vertical alveolar ridge measurements.
    RESULTS: The mean resorption rate in the HA/β-TCP and PLGA groups was ± 1.23 mm and ± 0.1 mm, respectively. A minimal alveolar bone height reduction of HA/β-TCP was observed after 9 months, the reduction showed a slight decrease to 0.93 mm, while this rate was 0.04 mm after 9 months in the PLGA group. Moreover, the bone height was maintained after three months, indicating a good HA/β-TCP graft performance in preserving alveolar bone (1.04 mm) while this rate was (0.04 mm) for PLGA.
    CONCLUSIONS: The PLGA graft demonstrated adequate safety and efficacy in dental socket preservation following tooth extraction. However, HA/β-TCP causes greater resorption at augmented sites than PLGA, which clinicians should consider during treatment planning.

    背景:由于血清肿形成是自体乳房重建后常见的供体部位并发症,我们通过引入渐进式张力缝线(PTS)调整了手术方案.本研究旨在评估自体乳房重建中供体部位PTS对血清肿形成的影响。此外,对患者满意度和美学结果进行了探索性分析.
    方法:这项回顾性队列研究分析了2018年至2022年接受自体乳房重建的400例患者的数据。其中,204名患者接受了传统的供体部位封闭,188例患者接受有或没有引流的PTS治疗。描述了血清肿的比例发生率,并使用多变量逻辑回归来评估血清肿形成的危险因素。在深腹壁下动脉穿支供区,通过给予BREAST-Q进一步探索患者满意度,并由3名盲组参与者对美学结局进行分级.
    结果:总体而言,对400例患者进行了514例乳房重建。与传统闭合组相比,PTS组的血清肿形成发生率较低。多变量分析表明,接受PTS的患者发生血清肿的可能性降低了40%。如果执行PTS,则客观和主观地认为美学结果更令人愉悦。关于患者满意度,两组的术后身体健康状况无差异.
    结论:在这个大型队列中,我们发现进行PTS时血清肿的发生率降低.PTS还与血清肿形成的几率降低有关,并被描述为在美学上更令人愉悦。在自体乳房重建中应考虑PTS。
    BACKGROUND: As seroma formation is a common donor site complication following autologous breast reconstruction, we adapted the surgical protocol by introducing progressive tension sutures (PTS). This study aimed to evaluate the influence of PTS at the donor site in autologous breast reconstruction on seroma formation. Additionally, an exploratory analysis on patient satisfaction and aesthetic outcome was performed.
    METHODS: This retrospective cohort study analyzed data of 400 patients who received autologous breast reconstruction between 2018 and 2022. Among them, 204 patients received traditional donor site closure, and 188 patients received PTS with or without drain placement. Proportional incidence of seroma was described and multivariable logistic regression was used to assess the risk factors for seroma formation. At the deep inferior epigastric artery perforator donor site, patient satisfaction was further explored by administering the BREAST-Q and the aesthetic outcome was graded by three blinded participants.
    RESULTS: Overall, 514 breast reconstructions were performed on 400 patients. The incidence of seroma formation was lower in the PTS group compared with that in the traditional closure group. Multivariable analysis showed that patients who received PTS were 40% less likely to develop seroma. Aesthetic outcome was considered more pleasing objectively and subjectively if PTS were performed. Regarding patient satisfaction, no difference was found in the post-operative physical well-being between the two groups.
    CONCLUSIONS: In this large cohort, we found reduced incidence of seroma when PTS were performed. PTS were also associated with reduced odds of seroma formation and were described to be aesthetically more pleasing. PTS should be considered in autologous breast reconstruction.

    背景:缺血再灌注损伤(IRI)是一种影响移植存活的现象。我们研究的目的是检查IRI在暴露于长时间热缺血的同基因和同种异体肌肉和皮肤移植模型中的作用。
    方法:使用48只Lewis大鼠和16只Brown-Norway大鼠创建四组:等基因腹股沟皮瓣移植(IST),等基因腓肠肌皮瓣移植(IMT),同种异体腹股沟皮瓣移植(AST),同种异体腓肠肌皮瓣移植(AMT)。在术后第1、7、21、35、63、100和120天测量所有组的丙二醛(MDA)和超氧化物歧化酶(SOD)水平。在术后第7、21、35、63、100和120天,在同种异体组中评估外周血中的供体特异性嵌合状态(DSC)。在术后第1、7和120天评估所有组的microRNA-21和microRNA-205水平。在研究结束时,进行了组织病理学检查.
    结果:在MDA和SOD水平方面,各组之间存在统计学上的显着差异。在AMT组中检测到DSC。观察到microRNA-205的显着增加,尤其是AMT组。肌肉移植组之间的功能肌肉单位数量没有显着差异。
    结论:在AMT组中存在DSC以及在IMT和AMT组中功能肌肉单位数量缺乏显著差异是值得注意的发现。
    BACKGROUND: Ischemia-reperfusion injury (IRI) is a phenomenon that affects transplant survival. The aim of our study was to examine the effects of IRI in isogenic and allogeneic muscle and skin transplantation models exposed to prolonged warm ischemia.
    METHODS: Forty-eight Lewis rats and 16 Brown-Norway rats were used to create four groups: Isogenic Inguinal Flap Transplantation (IST), Isogenic Gastrocnemius Muscle Flap Transplantation (IMT), Allogeneic Inguinal Flap Transplantation (AST), and Allogeneic Gastrocnemius Muscle Flap Transplantation (AMT). Malonyldialdehyde (MDA) and superoxide dismutase (SOD) levels were measured on postoperative days 1, 7, 21, 35, 63, 100, and 120 in all groups. Donor-specific chimerism (DSC) in peripheral blood was evaluated in the allogeneic groups on postoperative days 7, 21, 35, 63, 100, and 120. The microRNA-21 and microRNA-205 levels were evaluated on postoperative days 1, 7, and 120 in all groups. At the end of the study, a histopathological examination was performed.
    RESULTS: A statistically significant difference was found between the groups in terms of MDA and SOD levels. DSC was detected in the AMT group. A significant increase in microRNA-205 was observed, especially in the AMT group. There was no significant difference in the number of functional muscle units between the muscle transplantation groups.
    CONCLUSIONS: The presence of DSC in the AMT group and the lack of a significant difference in the number of functional muscle units in the IMT and AMT groups are noteworthy findings.
