The aim of this study was to assess tolerability, complications rate and clinical efficacy of peritoneal port-systems in patients with abdominal carcinomatosis. Material and methods: In our study 10 patients with abdominal carci- nomatosis were included. Ovarian cancer n=3, stomach cancer n=7. The main indication was ascites control deterioration. Mean age was 47 y.o. Implantation performed as follows: peritoneal punction under ultrasound(US) control and ascites evacuation (mean volume - 11 litres); by US naviga- tion the safe “window” on the abdominal wall was detected and marked; by surgical incision catheter was admitted into peritoneal cavity on the left paraumbilical area; port capsule was implanted on the left costal arch; to asses catheter tip localisation abdominal CTs or X-Ray examinations was performed. Every patient was included in observational program. Results: In all cases there weren’t technical difficulties during surgery. Mean time for ascites disappearance was 4 weeks and it was assessed as a good disease control. Mean time for disease progression was 3 months (2 - 5). In 1 case patient still alive more than 9 months (on the Feb 2019). In 2 cases at month 2nd after implantation local infection was revealed and devices were explanted. Conclusion: Peritoneal port-system is a useful device for supportive and palliative care in patients with abdominal carcinomatosis and ascites progression. based on our experience we suggest to active use presurgery CT (MRI) and intraoperatively ultrasound to identify safe incision acces. In most cases peritoneal port-a-cath provide patient with applicable quality of life and potentially may increase time to systemic disease progression
