Pure laparoscopic living donor liver transplantation: Dreams come true

Minimally invasive approaches are increasingly being applied in surgeries and have recently been used in living donor hepatectomy. We have developed a safe and reproducible method for minimally invasive living donor liver transplantation, which consists of pure laparoscopic explant hepatectomy and pure laparoscopic implantation of the graft, which was inserted through a suprapubic incision. Pure laparoscopic explant hepatectomy without liver fragmentation was performed in a 60-year-old man with alcoholic liver cirrhosis and hepatocellular carcinoma. The explanted liver was retrieved through a suprapubic incision. A modified right liver graft, procured from his 24-year-old son using the pure laparoscopic method, was inserted through a suprapubic incision, and implantation was performed intracorporeally throughout the procedure. The time required to remove the liver was 369 min, and the total operative time was 960 min. No complications occurred during or after the surgery. The patient recovered well, and his hospital stay was of 11 days. Pure laparoscopic living donor liver transplantation from explant hepatectomy to implantation was performed successfully. It is a feasible procedure when performed by a highly experienced surgeon and transplantation team. Further studies with larger sample sizes are needed to confirm its safety and feasibility.

     

Use of the Rocket Technique after Failure of the Direct Aspiration First-Pass Technique in Acute Stroke Thrombectomy

The technical feasibility of the rocket technique was evaluated for patients treated for stroke where the direct aspiration first-pass technique (ADAPT) failed to reach the occlusion site. This single-center retrospective study included data on consecutive patients with a large vessel occlusion of the anterior circulation who underwent mechanical thrombectomy. Of 138 patients, 100 met the inclusion criteria. In 84 patients, a large 0.072-inch inner lumen aspiration catheter was able to reach the occlusion site when deployed with a coaxial microcatheter. In 16 patients, this technique failed, and the microcatheter was replaced with a compliant balloon inflated at the extremity of the aspiration catheter (rocket technique). In 15 of these 16 patients, the rocket technique brought the catheter into contact with the thrombus. In conclusion, when deployment of the ADAPT with a coaxial microcatheter fails to reach the clot site, the rocket technique can safely advance the aspiration catheter to the clot.     

基于基因表达谱相似性的四物汤重定位及抗乳腺癌有效成分群辨识＊

目的 发现四物汤的新药理作用并辨识其有效成分群。方法 于GEO和Cmap数据库获取四物汤和1309个小分子药物的基因表达谱，计算差异表达基因及四物汤与1309个小分子药物的基因表达谱间的相似性，相似性较高的小分子药物的药理作用为四物汤的新药理作用。相似性较高的小分子药物的靶点作为四物汤发挥新药理作用的靶标，利用分子对接技术辨识四物汤的有效成分群。结果 四物汤具有抗乳腺癌的作用，其有效成分群为荭草苷、芍药苷和半乳糖醛酸等，并通过文献调研验证了辨识结果的可靠性。结论 本研究将为扩大四物汤的临床应用范围及质量控制奠定基础，为乳腺癌的治疗提供新方法。     

改良眶隔法和传统睑板法切开重睑术的术后重睑形态、瘢痕发生率、角膜暴露率比较研究

目的 比较改良眶隔法和传统睑板法切开重睑术中的应用效果及对术后重睑形态、瘢痕发生率、角膜暴露率的影响。方法 选取2020年3月-2021年3月首都医疗爱育华医院收治的80例单睑患者，采用随机数字表法将其分对照组和观察组，各40例。对照组接受传统睑板法切开重睑术，观察组接受改良眶隔法切开重睑术，比较两组术后重睑形态、瘢痕发生率、角膜暴露率、并发症发生率。结果 观察组总有效率高于对照组，差异有统计学意义（P＜0.05）；观察组GAIS评分高于对照组，VAS评分低于对照组，差异有统计学意义（P＜0.05）；观察组右侧角膜暴露率增加值、左侧角膜暴露率增加值高于对照组，差异有统计学意义（P＜0.05）；观察组并发症发生率为5.00%，低于对照组的22.50%，差异有统计学意义（P＜0.05）。结论 相比于传统睑板法切开重睑术，改良眶隔法切开重睑术不会过度增加术后角膜暴露率，术后瘢痕发生率更低，重睑形态更理想，患者接受度更高。     

输卵管疾病的生育力保护

输卵管因素不孕症占不孕人群的30%～35%。随着腹腔镜技术及微创手术原则的应用，生殖相关输卵管性疾病的微创手术治疗受到关注。手术治疗输卵管性不孕在评估输卵管功能，保留生育功能，改善患者自然妊娠或辅助生殖技术助孕的结局方面具有重要作用。文章主要对有生育要求的输卵管病变患者，腹腔镜手术保留及恢复生育功能的处理及临床结局进行阐述。
