Viabilidad y valor clínico de la sonda de imagen luminal funcional del píloro en un lactante

Pyloric dysfunction is becoming increasingly recognized as a cause of gastroparesis, but its diagnostic and therapeutic role in infants has not been well studied. Identification and treatment of pyloric dysfunction with functional luminal imaging probe (FLIP) technology or use of pyloric inhibition are not routinely used in infants due to lack of standardized parameters and safety concerns. We report the first known case of pyloric distensibility testing in an infant in which identification of low pyloric distensibility and subsequent therapeutic balloon dilatation and intrapyloric botulinum toxin injection resulted in marked and sustained improvement in gastric feeding tolerance. This case highlights the feasibility, safety, and clinical effectiveness of FLIP as a diagnostic and treatment tool in an infant with pyloric dysfunction. Better characterization of infant pyloric distensibility offers the possibility of evidence-based treatment strategies for feeding intolerance attributed to pyloric dysfunction.
