Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has been increasingly utilized for peritoneal surface malignancies. This has been commonly utilized for a variety of neoplasms, but, especially mucinous neoplasms of the appendix, ovarian cancer, gastric cancer, colorectal cancer and mesothelioma. Traditionally, CRS/HIPEC has been performed as an open, extensive operation associated with prolonged hospitalization. However, when the peritoneal carcinomatosis index (PCI) is small (<10), minimally invasive approaches can be considered. Such less invasive approaches may be associated with improved postoperative recovery, less complications while preserving oncologic outcomes. The robotic platform offers distinct advantages over laparoscopy with superior visualization and ergonomics which account for its increased utilization in oncologic surgery. Herein, we review available data on minimally invasive approaches to CRS/HIPEC procedures, focusing on patient selection and comparative studies to open CRS/HIPEC. We summarize the existing initial studies on robotically assisted CRS/HIPEC and provide technical insights about our approach to robotically assisted CRS/HIPEC. Current data suggests that treatment of peritoneal surface malignancies with minimally invasive CRS/HIPEC is feasible in selected cases and is associated with improved postoperative recovery. The robotically assisted platform for CRS/ HIPEC deserves further investigation and may improve outcomes after this procedure in the future for carefully selected patients with low PCI.
