A prospective analysis of factors influencing outcome after fundoplication☆

Abstract 

Fundoplication remains a common operation in the braindamaged pediatric patient, but recent reports suggest a poor outcome in these patients. The factors that might be associated with complications or recurrence after fundoplication have not been extensively examined. Fifty-six brain-damaged children, aged 6 months to 12 years, with documented gastroesophageal (GE) reflux underwent preoperative nutritional evaluations (percentage of ideal weight, albumin, nutrition risk index [NRI]) and documentation of medications (dexamethasone for bronchopulmonary dysplasia) before standard Nissen fundoplication. Hospital stay, intensive care unit (ICU) stay, and time on ventilator, as well as major postoperative complications (wound infection/dehiscence, pneumonia) were prospectively analyzed. Survival and recurrence rates 1 to 3 years postoperatively were also assessed. Eighty-two percent of patients were <90% ideal weight, and 50% had NRI < 90 (normal = 100) and 29% had albumin < 3.5 g/dL. Albumin < 3.5 was significantly (P < .01) associated with prolonged hospitaliaation (26.8 + 2.2 versus 15.1 + 1.1 days) and ICU stay (13.8 + 1.0 versus 4.4 + .5 days) and time on ventilator (8.0 + 1.0 versus 1.8 + .4 days). NRI < 90 showed similar significant differences (P < .01). Ideal body weight < 90% was not significant. Major complications developed in 54% of patients; only two or more preoperative nutritional deficiencies, or a nutritional deficiency plus dexamethasone were significantly associated (P < .01). Recurrence occurred in 21% of patients and was significantly and especially when dexamethasone plus a nutritional deficit were present (low albumin, P < .001; low NRI, P < .005). No factor correlated with survival. These data show that preoperative nutritional status greatly affects short- and long-term results after fundoplication, especially when steroids are also administrred, suggesting that preoperative nutritional support might benefit these patients.
