Abstract

During the postoperative phase of lung transplantation, the surgical creation of a gastro-jejunostomy (GJ) may be deemed necessary for patients with severe oesophageal dysmotility, prolonged oral intake difficulties stemming from use of a ventilator or marked malnutrition. We explored the effects of postoperative GJ tube on survival and bronchiolitis obliterans syndrome in lung transplant recipients. We retrospectively reviewed all lung transplants performed at our institution between 2011 and 2022. Propensity score matching was performed to match patients who required a GJ tube with control patients on a 1:1 ratio. The preoperative, operative and postoperative outcomes of the patients were evaluated. After propensity score matching, 193 patients with GJ were compared to 193 patients without GJ. Patients with GJ had significantly higher rates of delayed chest closure (P = 0.007), and postoperative dialysis (P = 0.016), longer intensive care unit stays (P < 0.001), longer ventilator duration (P < 0.001), higher rates of pneumonia (P = 0.035) and higher rates of being treated for acute cellular rejection within 1 year of transplant (P = 0.008). Overall survival and freedom from bronchiolitis obliterans syndrome were not found to be significantly different between the matched groups (P = 0.09 and P = 0.3). GJ tube placement during the postoperative phase of lung transplantation did not compromise patient survival or freedom from bronchiolitis obliterans syndrome although the results reflect more difficult and complicated cases. This study indicates that the GJ tube may be a useful option for enteral feeding.
