Management with Conservative Gastrointestinal Decompression and Intravenous Immunoglobulin Relieved Intestinal Obstruction in Kawasaki Disease: A Case Report

Background: Kawasaki disease (KD) is an acute febrile vasculitis that predominantly affects children under five years of age. Although gastrointestinal symptoms are common, severe complications, such as intestinal obstruction, are rare but clinically significant. Case Presentation: A 1-year and 7-month-old girl diagnosed with KD developed transient intestinal obstruction, presenting with bilious vomiting and hypochloremic alkalosis. Despite initial treatment with intravenous immunoglobulin (IVIG) and aspirin (ASA), her gastrointestinal symptoms worsened. Gastrointestinal imaging revealed an incomplete jejunal obstruction. Conservative management with intestinal decompression resolved the obstruction without surgical intervention, and the patient fully recovered without coronary complications. Conclusion: Intestinal obstruction in KD is rare but should be recognized, particularly in atypical presentations. Conservative approaches, including intestinal decompression combined with IVIG and aspirin administration, can be effective alternatives to surgical interventions.
