Estenosis duodenal por páncreas anular. Presentación de un caso esporádico. Duodenal stenosis for annular páncreas. A sporadic case presentation
Abstract
La obstrucción intestinal duodenal es frecuente en el recién nacido como causa de oclusión, puede ser completa (atresia duodenal) secundaria a un trastorno de revacuolización de la luz intestinal o por una rotación irregular del páncreas hacia la derecha del duodeno. Presentamos a un recién nacido con edad gestacional de 35.4 semanas, conteo de Apgar de 8-8 puntos, que nace con signos de shock hipovolémico secundario a una anemia aguda por desgarro del corión, con una Encefalopatía Hipóxica Isquémica(EHI). Desarrolló posteriormente una intolerancia digestiva con abundante residuo gástrico, valorándose una oclusión intestinal incompleta alta, posiblemente por una estenosis duodenal. Se le realizan radiografías de abdomen simple de pie apoyándose la sospecha clínica por la presencia de imagen típica "en doble burbuja", se realizó laparotomía exploradora encontrando en el acto quirúrgico una Estenosis Duodenal secundaria a un Páncreas Anular. Es egresado a los 45 días de vida con buen peso corporal y reflujo gastroesofágico grado III como complicación. Actualmente se encuentra bajo seguimiento ambulatorio multidisciplinario y en franca evolución satisfactoria.

ABSTRACT
Duodenal intestinal obstruction is frequent in newborn as a cause of occlusion, it can be complete (duodenal atresia), secondary to a disorder of revacuolization of the intestinal lumen, or due to an irregular rotation of pancreas towards theright of duodenum. A newborn with a gestational age of 35.4 weeks, apgar score of 8.8 who was born with signs of hypovolemic shock secondary to an acute anemia caused by chorion tear with an Ischemic Hypoxic Encephalopathy, who subsequently deveoped a digestive intolerance with abundant gastric residue. An incomplete intestinal occluson was assessed - possibly as a result of a duodenal stenosis - simple abdominal X - rays was performed, supporting clinical suspicion because of the presence of a typical image in "double bubble". An exploratory laparatomy was carried out, finding in surgery a Duodenal Stenosis secondary to an annular Pancreas. The patient was discharged from the hospital 45 days after being born with a good weight and as complication a gastroesophageal reflux of third degreee. Currently the patient undergoes ambulatory-multidisciplinary follow-up, and is making a satisfactory progress.
