The most frequent peritoneal surface malignancies originate principally by gastric cancer, colorectal cancer and ovarian cancer. Apart from the origin, peritoneal carcinosis (PC) is considered a negative prognostic factor. The hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal malignancies is considered an attractive method to deliver chemotherapy with enhanced effect directly at the tumor site. The use of such loco-regional approach has proved to improve prognosis of peritoneal carcinomatosis from different origins. Recently, new devices are suitable for loco-regional intraperitoneal chemotherapy as Peritoneal Recirculation System (PRS-1.0 Combat) with CO(2) technology. This is a retrospective study with the aim to assess the perioperative outcomes using PRS. Seventeen patients were enrolled affected by colorectal or ovarian cancer. Complete cytoreduction (RTâ€‰=â€‰0) was achieved for all cases. Median operative time was 420Â min (range: 335-665) and median drugs dose used for HIPEC was 137Â mg/m2 (115-756). Median EBL was 200Â ml (range 50-1000). Median post-operative hospital stay was 9Â days (range: 4-24). Treatment-related early complications were recorded in 8 (47.0%) cases and were G1-G2 Major complications occurred in two (11.7%) cases. Considering our aim to test the PRS in different cases and in different pathologies, the results confirmed that the technique is feasible with good perioperative outcomes.
