OBJECTIVE: Egg binding is a common and potentially life-threatening disorder in avian species. The aim of this study was to analyze the success rate and associated complications of different treatment approaches for egg binding in parrots.
METHODS: All parrots treated in an avian-exclusive veterinary practice for egg binding during an 11-year period (2009 to 2020) were eligible for inclusion in this retrospective study. The primary outcome of the study was resolution of egg binding, defined as removal or laying of the egg and survival at 7 days from presentation.
RESULTS: Of the 150 events that had complete follow-up, 109 (72.7%) resulted in a successful outcome. A successful outcome was observed in 44 of 133 events (33.1%) that were initially managed medically without resorting to additional treatment strategies, in 31 events (86.1%) managed with mechanical assistance, in 20 events (60.6%) managed surgically, and in 12 events (85.7%) managed with ovocentesis. Time from presentation to resolution was a median of 36 hours (range, 1 to 240 hours; n = 119). Multivariable logistic regression demonstrated associations between higher body weight, administration of medical treatment and mechanical assistance, absence of administration of sedation or anesthesia, and absence of obtundation or stupor on presentation with a positive outcome.
CONCLUSIONS: Overall, egg binding has a favorable outcome if multiple treatment strategies in addition to medical management are considered.
CLINICAL RELEVANCE: We identified factors associated with resolution and outlined complications of egg binding in parrots, laying the foundation for additional prospective research on this complex condition.
