Routine elective gastrojejunostomy tube changes are associated with reduced tube complications and radiation exposure.

Gastrojejunostomy tubes (GJTs) can be a long-term solution for patients with intragastric feeding intolerance. Our retrospective study of 101 patients correlates the frequency of routine and urgent GJT changes, as well as complications, and radiation exposure. Over a 2.75 year median duration, 60, 33, and 28% of patients had ≥1 episodes of a tube dislodgement/malpositioning, blockage, or leakage respectively. Aspiration pneumonia hospital admission was required for 23% of patients. Patients with ≤1 routine tube change/year had more urgent changes/year (3.0) compared to patients with 1-2 (1.2) or >2 (0.8) routine yearly change. These patients required more frequent sedation for tube placement (21% vs 4.7% p=0.03) and experienced greater annual radiation exposure (9599 vs. 304.5 and 69.1 μGym2, p=0.01 and 0.008 respectively). Overall, aiming for a routine tube change at least every 6-12 months is associated with fewer urgent changes and complications as well as reduced radiation exposure and sedation requirements.
