目的 依托四川大学华西医院的临床资源，建立了一个规范化、标准化的肿瘤组织标本库，对临床医学研究提供了珍贵的资源。 方法 于2009年6月创建四川大学华西医院肿瘤组织标本库、进行质量控制、规范化管理及总结实践经验。 结果 从创建肿瘤组织标本库至2012年2月，共收集各类肿瘤（胃、食管、肝、肺、肠、乳腺、胰腺、甲状腺、纵隔、肾脏、喉、脑）组织标本44 609例，包括肿瘤组织、肿瘤旁组织（距离肿瘤组织2 cm的组织）和切缘远端非肿瘤组织（距离肿瘤组织＞5 cm的组织）。对肿瘤组织标本进行有效和科学的管理，为科研提供了便利和高质量的资源。 结论 建立了一个国际标准化、规范化、信息完善的肿瘤组织标本库，可为肿瘤的发生、发展、转移及生物标志物的研究提供高质量的标本。
ObjectiveTo summarize the clinical experience of retropancreatic tunnel established by superior mesenteric vein-approach in a child with cavernous transformation of the portal vein (CTPV) during Rex bypass. MethodThe retropancreatic tunnel was created by the superior mesenteric vein-approach during Rex bypass in a child with CTPV who was admitted to our hospital in September, 2023. Clinical data were retrospectively analyzed. ResultsFor the 4-year-old male child who was diagnosed with CTPV, after the establishment of the retropancreatic tunnel by superior mesenteric vein-approach, the portal vein was quickly identified, thus simplifying the portal dissection. The operation time of Rex bypass was about 8 hours, and intraoperative blood loss was about 60 mL. After a 3-month follow-up, the child recovered well with patent bypass vessels. ConclusionThe surgical strategy proposed by our team can simplify the Rex bypass, resulting in more rapid and safe access to the vascular anastomosis site.
