Simultaneous, single-docking robotic resection for right colon cancer with synchronous liver metastases.

BACKGROUND: How best to manage colorectal cancer patients presenting resectable synchronous liver metastasis is still a matter of debate. A number of different available therapeutic strategies exist, with significant differences in terms of optimal timing and/or sequence of resection of the primary tumor and liver disease [1]. Over the last years, simultaneous resections are increasingly adopted for properly selected patients [1-3]. However, the application of minimally invasive surgery to combined colorectal and liver surgery is still controversial, especially in the case of liver disease requiring technically demanding resections [2,3]. VIDEO: The presented video illustrates the details of a single-docking robotic right colectomy combined with ultrasound-guided, parenchymal-sparing resection of liver segments 6 and 7, as performed to treat a patient with locally advanced colorectal cancer and metastatic disease isolated to the right liver. Port placement strategy and main instrumentation employed are illustrated in Fig. 1, and Fig. 2, respectively. The total duration of surgery was 380 minutes. The hepatic hilum was encircled to allow extracorporeal Pringle maneuver during liver resection, though no clamping was eventually required. Right colectomy with central vascular ligation was thus carried out and an intracorporeal ileocolic anastomosis performed. The patient had an uneventful postoperative course. CONCLUSIONS: When feasible, minimally invasive simultaneous resection may offer distinct advantages over conventional surgery while respecting the tenets of appropriate oncological resection [2,3]. The well-known benefits of minimally invasive surgery, including shorter overall hospital length of stay, reduced morbidity, and lower blood loss, are combined with the need to recover from a single major surgery. Robotic resection may be particularly suited for technically challenging procedures, such as colectomy combined with liver metastasectomies with unfavorable anatomical accessibility [3,4].
