Background: Rectal cancer patients with synchronous liver metastases (SLM) is common in clinical practice. However, the application of conventional natural orifice specimen extraction surgery (NOSES) and NOSES with specimen extraction via stoma/hepatectomy incision in the special population is rarely explored.
Case report: Six SLM rectal cancer patients were treated with simultaneous surgical resection and the specimens were extracted via anal/stoma/hepatectomy incision. Respectively, intraoperative and postoperative data, anal function 3 months after surgery and long-term prognosis were reviewed.
Results: Intraoperative and postoperative data and anal function were reliable for the six cases. Only one patient died of brain and bone metastases at 84 months after surgery and the other five patients were alive at their last follow-up.
Conclusions: Simultaneous surgical resection with the concept of conventional NOSES and NOSES with specimen extraction via stoma/hepatectomy incision is safety for SLM rectal patients.
