Efficacy of same venous route Hickman catheter replacement in patients with intestinal failure

Background/purpose: Periodical replacement of venous Hickman catheters is required for the nutritional care of patients with intestinal failure. The conventional de novo operation (DN-OP) involves inserting the catheter into a new venous tract in each replacement; however, this could result in fast consumption of functional central vessels in patients with intestinal failure. Recently, same-route operation (SR-OP) has been adopted as an alternative approach for retaining venous access. Methods: We conducted a retrospective study to compare the efficacy of Hickman catheters and the survival of venous vessels using two different operative strategies. Results: Overall, 181 catheters were inserted, 109 using DN-OP and 72 using SR-OP. The mean catheter duration was 11.9 ± 8.8 months in the DN-OP group and 10.5 ± 5.6 months in the SR-OP group; the infection rate was 0.74 in the DN-OP group and 0.44 in the SR-OP group. The vein accesses used in these insertions (n = 113) were classified: the DN-vein group for veins accessed only by DN-OP (n = 75) and the SR-vein group for veins accessed by an initial DN-OP and subsequent SR-OPs (n = 38). Mean working duration per vein access was 12.3 ± 10.1 months in the DN-vein group and 28.2 ± 14.8 months in the SR-vein group (p
