Robot-assisted one-stage resection of rectal cancer with liver and lung metastases

Figure 1 Preoperative positron emission tomography showed rectal cancer with liver and lung metastases. A and B: Rectal cancer; C and D: Lung metastasis; E and F: Liver metastasis.

Figure 2 Robot-assisted wedge-shaped resection of the right lobe for lung metastasis. A: Arrow indicates tumor location; B: Arrows indicate the cut line of the Endo GIA stapling device.

Figure 3 Robot-assisted segmental hepatectomy for liver metastasis. A: Intraoperative ultrasound was used to mark tumor location; B: The tumor was resected.
