Accurate patient selection is therefore essential for determining eligibility for this type of\u00a0surgery. The peritoneal carcinomatosis index (PCI) is a widely used tool for assessing the extent of carcinomatosis. This study aimed to evaluate the inter-observer reproducibility of PCI assessments via laparoscopy and identify factors influencing this reproducibility.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_pp-2024-0015_abs_002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Between November 2020 and November 2022, 25\u00a0laparoscopic PCI assessment videos were reviewed by\u00a0six surgeons from two centers.
