晚期脾曲肿瘤并不常见，且复发风险较高。为了确保切除范围包括整个淋巴引流区域并进行完整的结肠系膜切除（CME），需要进行左侧结肠扩大切除术。在腹膜癌病中，结肠西格玛和脾曲常常广泛受累。在许多情况下，即使可以保留大部分结肠，也会为这些患者选择全结肠切除术。讨论了脾曲结肠切除术后对生活质量的潜在影响，以及解剖知识和专业知识在执行此类手术中的重要性。总体而言，这项工作提出了一种改良技术，旨在改善脾曲结肠癌患者的预后和生活质量。在扩大左侧结直肠切除术后建立无张力吻合具有挑战性。回肠直肠吻合术会对生活质量产生负面影响。改良 Rosi-Cahill 或 Deloyers 技术后进行的结直肠吻合术可以减少小肠细菌过度生长，实现更好的水和钠吸收，并总体上改善粪便稠度。与 Deloyers 手术等其他流行选择相比，Rosi-Cahill 技术具有潜在优势，因为没有回结肠血管扭转，也没有肠系膜窗口。录制的视频显示了 Deloyers 技术中潜在的缺陷，导致肠系膜窗口的形成。还拍摄了改良罗西-卡希尔手术期间结肠的正确旋转。总体而言，这项工作提出了一种改良的左扩大结肠切除术后重建技术，旨在改善脾曲结肠癌患者的预后和生活质量。© 2024。作者。

Advanced splenic flexure tumors are uncommon and have a higher risk of relapse. To ensure that the resection includes the entire area of lymphatic drainage with a complete mesocolic excision (CME), a left extended colectomy is needed. In peritoneal carcinomatosis, there is often extensive involvement of the sigma and splenic flexure of the colon. In many instances, total colectomies are chosen for these patients, even when a significant portion of the colon could be preserved. The potential impact on quality of life after splenic flexure colon resection is discussed, as well as the importance of anatomical knowledge and expertise in performing this type of surgery. Overall, this work presents a modified technique that aims to improve the outcomes and quality of life for patients with splenic flexure colon cancer. Creating a tension-free anastomosis after extended left-sided colorectal resection is challenging. There is a negative impact on quality of life when an ileorectal anastomosis is created. The colorectal anastomosis performed after modified Rosi-Cahill or Deloyers' technique allows reduced small bowel bacterial overgrowth, achieves better water and sodium absorption, and altogether permits improved stool consistency. There are potential advantages of the Rosi-Cahill technique over other popular options such as Deloyers' procedure as there is no torsion of the ileocolic vessels and no mesenteric windows. A video was recorded showing a potential pitfall during Deloyers' technique resulting in the creation of a mesenteric window. The proper rotation of the colon during the modified Rosi-Cahill procedure was also filmed. Overall, this work presents a modified technique for reconstruction after left extended colectomy that aims to improve the outcomes and quality of life for patients with splenic flexure colon cancer.© 2024.
