Objectives: To investigate the outcomes of 34 patients with intestinal failure secondary to advanced peritoneal malignancy on home parenteral nutrition (HPN).
Methods: A retrospective analysis of all known patients receiving HPN at any time between January 2012 and the 31st March 2020 registered in a high volume peritoneal malignancy surgical centre database.
Results: The median duration of HPN for all patients was 309.5 days (range 31-2198). Overall 11/34 went on to have multivisceral transplants. Of these 5/11 resumed normal oral intake off HPN, 3 died and 3 required ongoing HPN. Average time on HPN for patients with pseudomyxoma peritonei of appendix origin was 338 days (71-2198) compared with 90 days (31-260) in the group with more aggressive tumours.
Conclusions: HPN is feasible and effective in selected patients with pseudomyxoma peritonei as either a bridge to transplant or definitive treatment. As expected, patients with more aggressive tumours fare worse.
