Fig. 1From: Right hemicolectomy with D3 lymph node dissection for right-sided transverse colon cancer using the Senhance robotic system: a case reportPort placement of a right hemicolectomy using the Senhance robotic system. a Setting A. Lymphadenectomy and dissection of the ileocolic artery (ICA) and vein (ICV) with mobilization of the right colon and separation of the outer side of the ascending colon from the retroperitoneum was performed using this port placement. b Setting B. Lymphadenectomy and dissection of the middle colic artery (MCA) was performed using this formation. The port for the fourth arm was inserted to expand the transverse mesocolon. Changing the port placement made it easy for the surgeon to identify the MCA by viewing the transverse mesocolon from the frontBack to article page
