Video S1 describes the technique in a stepbystep approach, using large overlay windows and eyecatching animations for an easier understanding of the surgical procedures (including parietal and pelvic totally laparoscopic peritonectomy).

After radical surgery, hyperthermic chemotherapy perfusion of peritoneum was performed using laparoscopic trocars for HIPEC inflow and outflow catheters. We present this video because it could be of interest to Colorectal Disease readers as this technique is quite new and not widely used.
