“…CRS/HIPEC was popularized by Sugarbaker, initially for Pseudomyxoma Peritonei (PMP) but its use was translated to colorectal peritoneal metastases. The rationale for this strategy is based on the ‘redistribution phenomenon’, which was initially described in perforated mucinous tumours of the appendix (Moran & Cecil, ; Sugarbaker, ). Free‐floating intraperitoneal cells accumulate at predictable sites within the peritoneal cavity including sites of normal peritoneal fluid absorption such as the omentum (hence the omental ‘cake’) and the under‐surface of the diaphragm (particularly the right), the effects of gravity resulting in disease in the pelvis and paracolic gutters, with relative sparing of motile organs, particularly small bowel unless there are adhesions from extensive prior surgery.…”
