该协议侧重于使用 mSLR 的 PD 重建阶段，并遵循德国鲁尔大学波鸿分校道德委员会的指导方针。
注：胰腺头、大肠状或严重难治性慢性钙化胰腺炎患者接受PD。如果肿瘤与围肠动脉的接触少于50%，且没有渗透门户静脉或优越的静脉。腺癌病例的远转移也是PD的禁忌症。PD 中的切除技术是标准化的，并在其他部分11、12中详细描述。它不...

迄今为止，POPF对PD1之后的术后发病率有显著贡献。
胆汁和胰腺汁的混合物可以导致两种分泌物的相互激活，增加对PJ或HJ9、13、14、15、16的不利影响。活性磷脂酶A2的细胞毒性活性，将胆汁卵磷脂转化为有害的利索西质，使胰腺麻醉风?...

胰腺切除术（PD）被认为是一个复杂的外科手术。虽然死亡率在过去几十年中有所下降，但发病率仍然很高。最频繁和害怕的并发症是术后胰腺瘘（POPF），它发生在超过20%的手术2，3，4，5。POPF可导致后续并发症，如产后造血、延迟胃排空、腹腔内脓肿和败血症。住院费用增加、住院时间过长、癌症患者化疗推迟，对2、3、4的社会经济影响巨大。
在过去的几十年中，人们采用了不同的手术方法来降低POPF的频率和严重程度。其中之一是双循环重建（DLR），与孤立的Roux-en-Y循环胆道和胰腺麻醉剂。胰腺汁从胆汁中分离出来被认为可以减少相互激活的分泌物对胰腺肌切除术（PJ）的有害影响。文学的结果一直鼓舞人心6，7，8。然而，使用DLR4，9，操作时间显著延长。
这里我们介绍了在PD期间修改的单循环重建（mSLR）技术，将胰腺分泌从胆汁中分离出来，而传统的单循环重建（SLR，图1）。在这种方法中，使用单个长的小肠环来构造肝热肌切除术（HJ）和PJ。HJ 的可致和可活动肢体之间的侧对侧麻醉有助于胆汁和胰腺分泌物的分离流动。2018年10月，我们小组报告了第一个有希望的结果，证实高危胰腺患者的死亡率和发病率有所下降。
与双循环重建相比，该方法通过分离胰腺液和胆汁来降低POPF的严重程度，同时不显著延长手术持续时间。

modified single-loop reconstruction for pancreaticoduodenectomy

胰腺切除术中修饰的单循环重建分离胰腺分泌从胆汁。它在高风险胰腺残留物的情况下进行，以减少术后胰腺瘘的严重程度，以及术后的整体发病率。这种重建技术的特点是为胰腺肌切除术和肝切除术的超长环。这些麻醉剂和另外一个济州-杰朱诺-杰尤诺索托法之间的长距离距离，使肝胆肌切除术分离液体，防止胆汁回流到胰腺肌切除术。因此，分泌物不能相互激活，并加剧现有的麻醉漏。与传统的单回路重建相比，经改造的单回路重建后，严重术后胰腺瘘的发生率降低。与传统的双循环重建相比，该技术易于执行、安全且耗时更少。

每个接受PD的患者都接受胰腺组织调查，以评估mSLR的指示。高风险胰腺残余物（即软胰腺组织和微小的主胰腺导管）尽可能使用经过修饰的单回路进行重建。
我们确定了50名高危胰腺组织和一个小主胰腺导管患者。他们都接受了mSLR。平均年龄为63~13岁。男女比例为17：33。手术适应症是33例患者恶性疾病（66%）和良性疾病在17个患者（34%）。平均操作时间是365~77分钟。该组与两?...

Modified Single-Loop Reconstruction for Pancreaticoduodenectomy

胰腺切除术后修饰的单循环重建技术将胰腺分泌从胆汁中分离出来，从而降低了POPF的严重程度，同时延长了手术时间。

胰腺切除术的改性单循环重建

胰腺分泌物与胆汁分离可减少相互激活分泌物对胰腺切除术的有害影响。这可降低术后胰腺管炎的严重程度，但不是发病率。单环重建是胰腺切除术中一种频繁进行的重建技术。双环重建于1976年首次引入。它实现了胰腺液和胆汁分离的理论。但是，与传统的单环重建相比，此过程要耗时得多。修改后的单环重建旨在将胰腺体液与胆汁分离，胆汁具有长的杰朱尔肢体，并在肝结切除术的异肢和发泡肢体之间增加一种杰朱纳尔肛门病。此图展示了经过修改的单环重建的胰腺切除术的完成重建阶段。绿色箭头演示胰腺结切除术、肝细胞切除术和杰朱诺耶肌切除术。在这张照片中可以清楚地看到超长的杰朱纳尔肢体。这项研究涉及人类手术的研究方案只得到了波鸿鲁尔大学伦理委员会的批准。所有患者都获得书面知情同意。这是准备的韧带补丁。它将被包裹在肝动脉后完成动脉的结膜病，以减少侵蚀出血的风险，在动脉瘤泄漏的情况下。开始重建阶段，固定一个长，移动的Jejunal循环。重新测量前 10 英寸的 jejunum， 以提供足够的长度的梅内蒂。在右上腹部象限中重新置置 jejunal 循环。进行双层地间导管到粘膜胰腺结膜切除术。对外层使用中断的聚二甲酮 5-0 缝合线，对内层使用中断的聚丙烯 5-0 缝合线。不需要支架或密封剂。此序列显示胰腺结膜内层的缝合与中断的聚丙烯 5-0 缝合。将缝合线彼此靠近，以避免动脉瘤功能不全。不要将缝合线放置得太近，以免缝合组织坏死。在这里，我们看到胰腺结膜切除术的外层与中断的多二酮5-0缝合的构造。缝合线按此顺序进行准备。再一次，不要把缝合线彼此太近。这是完成的双层到导管到粘膜胰腺结膜切除术。在构建肝结切除术之前，先建造杰诺耶诺切除术的外墙。这有利于肝切除术的建设。现在，我们可以清楚地看到长杰朱尔肢体将如何放置。肝切除术和胰腺切除术之间的杰朱纳尔循环测量25至35厘米，而不是10厘米。这创造了动脉瘤之间的距离，使分泌物的转移。它进一步促进在肝切除和肝切除的四肢之间再构建一个jejunojejun切除术。执行单层中断多二酮 5-0 缝合的肝素结膜切除术。用T管分离薄壁和微小的普通胆管。使用四个粘膜固定缝合线开始肝细胞切除术。两个聚丙烯 5-0 持有缝合线有利于肝细胞切除术的构建。使用中断的多二酮 5-0 缝合线开始构建肝素结膜切除术。准备手术结，但不要在开始时绑它们。准备好的手术结随后被绑上，使每个缝合线具有相等的张力。在这里，我们可以清楚地看到超长的Jejunal肢体修改的单环重建。在这里，我们看到肝切除术前墙的建造。jejenojejunostomy 是一种 1.5 厘米测量双层 jejunal 肛门病，用多二酮 5-0 缝合进行。在肝切除术和肝切除术的发性肢体之间的最低点构建动脉瘤。构建胰腺结切除术和肝细胞切除术的这种结石，因为它们是最复杂的。使用单极烧灼热打开jejunum，用于建造jejunojejunotomy。使用多二酮 5-0 缝合进行连续缝合，用于 jejunojejunostomy 后壁的内层。连续的苏特允许在动脉瘤上均匀分布张力。在这里，我们看到动脉瘤前壁内层的构造。这是前墙外层的构造。在这里，我们看到胰腺炎切除术，jejunojejun切除术，和肝细胞切除术的背景。在转位下肢后，缩小中异子龙的间隙，以避免内气喘。每个有软胰腺组织和小主胰管的患者都尽可能进行经过修改的单环重建。调动长杰朱尔肢体通常没有问题。在极少数情况下，由于极端的内脏肥胖或由于过去的手术史导致的严重粘附，动员受到限制。小病人在上腹部自然更小的空间，也妨碍了准备。在患者中，连续进行双层重建。术后无一功能不全。这种方法可减少所有高风险胰腺残留物患者严重术后胰腺管病的发生率。通过修改的单环重建，产后切除术出血和再手术的数量明显减少。与双环重建相比，此过程在技术上要求显著降低，耗时也更低。修改的单环重建是将胰腺分泌物与胆汁分离的简单技术，可降低术后发病率。与双环重建，它既安全又不耗时。
