Robotic and Laparoscopic Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy, Multicenter Study From Saudi Arabia

Abstract

BackgroundPeritoneal metastasis (PM) is a common evolution of abdominal tumors. Without aggressive multimodal treatment, it is associated with a poor prognosis. The aim of this study is to present a multicenter results from Saudi Arabia on minimally invasive CRS and HIIPEC.MethodsA retrospective analysis of a prospective maintained multicenter database was queried for all patients treated with laparoscopic or robotic CRS and HIPEC between 2019 and 2024 in Saudi Arabia. Surgical and oncological outcome was analyzed.ResultsEleven consecutive patients underwent minimally invasive CRS and HIPEC between 2019 and 2024. Eight patients (72.7%) were operated by laparoscopy, one of them by single port access and three patients (27.3%) were operated robotically. Six patients (54.5%) were female. Median age was 42 (29–64). Primary tumor was PMP from the appendix, colon, and MCM in 6 (54.5%), 4 (36.4%), and 1 (9.1%) respectively. The median duration to complete the surgical procedure for all patients was 330 (230–580) min and for robotic CRS the median docking time was 570 (330–580) min. Median PCI was 2 (1–7) and completeness Cytoreduction (CC score 0) was achieved in the all patients (100%). Median hospital stay was 8 days (3–20). Four patients had one night postoperative ICU stay. Major morbidity (CTCAE) 3 and 4 occurred in three patients (27.3%) (Port site hernia, bleeding, and wound infection). No readmission to the hospital and no 90 days mortalities.ConclusionThe minimally invasive approach by laparoscopy or robot is a feasible and promising option for CRS and HIPEC. It reduces the hospital stay, early return to intended oncological treatment (RIOT). Further prospective clinical studies are needed to evaluate this approach.
