BackgroundPIPAC is a recent approach for intraperitoneal chemotherapy with promising results for patients with peritoneal carcinomatosis (PC). We aimed to evaluate the postoperative outcome of PIPAC in patients with non-resectable PC during our initial experience of the technique.MethodsAll patients who underwent PIPAC for non-resectable PC in three centers were analyzed regarding postoperative outcomes.ResultsSeventy-three patients underwent 164 PIPAC. PC was from colorectal, gastric, ovarian, malignant mesothelioma, pseudomyxoma peritonei or other origins in 20, 26, 13, 8, 1 and 5 patients respectively. Forty-five (62%), 31 (42%), 8 (11%), 6 (8%), 1 (1%) patients underwent a second, third, fourth, fifth, and sixth PIPAC respectively. At the time of the first PIPAC, the median PCI was 17 (1–39), 57 patients presented with symptomatic PC (pain: 33; ascites: 35; transit disorder like diarrhea and constipation: 11). PCI improved in 64.5% of patients, 63.5% of patients presented with complete disappearance of symptoms. Major complications occurred as the outcome of 16 PIPAC (9.7%) and 5 (6.8%) patients died within 30 days of the PIPAC procedure. Rate of mortality and major complications 40% and 62% respectively occurred in first 20 treated patients. For 64 (88%) patients, systemic chemotherapy was associated with PIPAC and could be administered after PIPAC with a median delay of 14 days (2–28).ConclusionsImplementing a PIPAC program in association with systemic chemotherapy is feasible and is associated with a risk of postoperative morbidity, even in teams highly experienced in PC management and requires a learning curve in patient selection.

Synopsis: PIPAC is a recent approach for intraperitoneal chemotherapy with promising results for patients with PC. Implementing a PIPAC program in association with systemic chemotherapy is associated with a risk of postoperative morbidity, even in teams highly experienced in PC management.
