A 13-year-old male with a history of chronic congenital megacolon presented
to the emergency department with a 1-day history of increasing abdominal p
ain, distension, and emesis. The patient was admitted for bowel disimpactio
n and irrigation. The patient rapidly developed an acute abdominal compartm
ent syndrome because of his massive colonic dilation. Surgical decompressio
n resulted in a reperfusion phenomenon and ultimately resulted in coagulopa
thy and patient demise. This case presents a unique cause of the abdominal
compartment syndrome and discusses the implications to the emergency physic
ian.
