Strategy and technique for simultaneous resection of rectal cancer and liver metastasis

Abstract

Rectal cancer with simultaneous liver metastasis is very common clinically. R0 surgical resection both for the original and metastatic tumor can achieve much better long-term oncological results. The operation types include traditional open procedures for both rectal cancer and liver metastatic resection; combination of laparoscopic resection of the rectal cancer and open procedure resection of the liver metastatic lesion; traditional laparoscopic-assisted rectal and liver metastatic tumor resection with small abdominal incision and total laparoscopic natural orifice specimen extraction surgery(NOSES) without abdominal incision. Due to the complexity of rectal anatomy and treatment strategy, leading to the difference from colon cancer with liver metastasis, and due to the effect of laparoscopic treatment, especially the 3D laparoscopy, patient selection for simultaneous resection should be well planned and individualized by surgeons based on conditions of themselves and patients.
