Purpose: Rural and regional hospitals often have limited immediate access to fringe surgical equipment. Contributing to this are financial and geographic constraints, as well as unestablished relations with boutique distributors. Borne out of a clinical challenge, the aim of this project was to develop a wide-bore dual-channel irrigation drain for the management of large complex intra-abdominal and retroperitoneal collections. Methodology: This bench-to-bedside project involved the creation of several prototype drains fashioned from common equipment found within the surgical stockroom. A final design was settled upon, along with a streamlined process of construction. This drain was then implemented successfully in the clinical setting. Results: The novel PAFONIC drain (PAediatric FOley iN Intercostal Cather) was created out of a paediatric foley catheter, an intercostal catheter, 4 mm punch biopsy, and cyanoacrylate glue. It allows for drainage of large loculated collections whilst delivering intermittent or continuous irrigation to the containing cavity. During its period of clinical use there were no episodes of leak, fracture, or dislodgement. The cost of production was favourable in comparison to existing market devices. Conclusions: The PAFONIC drain is a safe and easy to construct wide-bore drainage-irrigation catheter that can be made with commonplace surgical equipment.
