Sinonasal evaluation and treatment before liver transplantation: a retrospective review of 982 patients.

Abstract

Immunosuppression after liver transplantation (LT) increases complications from infection. The usefulness of sinonasal evaluation before LT has not been fully evaluated. The aim of this study was to determine the usefulness of routine sinonasal evaluation before LT and pre-transplant treatment of sinusitis. The clinical records of 982 adult patients (age ≥18years) who underwent LT between January 1997 and June 2011 were retrospectively reviewed and analyzed. A total of 920 patients (93.7%) underwent pre-LT sinonasal evaluation, including a sinonasal symptom questionnaire, nasal endoscopy and plain X-ray. Of these patients, 269 (29.2%) had abnormal findings and underwent paranasal CT scans. Based on CT, 102 patients, including 21 with fungal ball, were diagnosed with sinusitis and 62 (60.8%) underwent LT after medical or surgical treatment for sinusitis. Another 40 patients (33 with sinusitis and 7 with fungal ball) underwent LT without treatment for sinusitis. No difference in infectious complications was observed according to sinusitis treatment type. Among chronic rhinosinusitis patients, those who underwent LT (n=48) after adequate treatment had a lower mortality rate than those who did not receive treatment (n=33) (12.5 vs. 33.3%; p=0.024). Sinonasal evaluation preceding LT did not prevent infectious complications but untreated sinusitis might be correlated with increased mortality after LT. Routine pre-LT sinonasal evaluation would be considered for safer transplantation.
