However, robot\u2010assisted resection of synchronous colorectal cancer (sCRC) remains technically challenging and unstandardized due to its rarity. Herein, we propose an N\u2010shaped configuration of five\u2010trocar placement for the simultaneous right\u2010 and left\u2010sided colectomies with intracorporeal anastomosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Surgical Technique<\/jats:title>\n                    <jats:p>An 85\u2010year\u2010old woman with synchronous cecal (T1) and sigmoid colon (T3) cancers underwent simultaneous ileocecal resection and sigmoidectomy. A camera trocar at the umbilical incision and four additional trocars were arranged in an N\u2010shaped configuration. The patient cart was docked from the left caudal side. Right\u2010sided colectomy was performed first with intracorporeal anastomosis using robotic stapling. Following temporary undocking and a 180\u2010degree boom rotation, the robotic sigmoidectomy was completed with a standard double\u2010stapled anastomosis. Total operative time was 311\u2009min with minimal blood loss, and the postoperative course was uneventful.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This N\u2010shaped port configuration facilitated a seamless transition between right\u2010 and left\u2010sided colectomies, maximizing the advantages of robotic surgery. Importantly, all tasks can be completed with this port configuration by a single patient\u2010side surgeon. Although further studies are needed to evaluate the adaptability of this approach to other multiport robotic platforms, our experience suggests this technique is practical and effective for multiport robotic sCRC resections.<\/jats:p>\n
