title: Prolonged postprandial abdominal pain following Kawasaki syndrome with acute gallbladder hydrops: association with impaired gallbladder emptying.
abstract: Acute hydrops of the gallbladder is a well-recognized complication of Kawasaki syndrome. We report a case of a child with this syndrome whose gallbladder hydrops slowly resolved after intravenous gamma-globulin therapy. However, he continued to experience postprandial right upper quadrant abdominal pain. Hepatobiliary scintigraphy revealed normal filling of the gallbladder but marked impairment of meal-stimulated gallbladder emptying. Endoscopy with biopsy of the esophagus, stomach, and duodenum was normal, ruling out peptic complications of his aspirin therapy. This child's discomfort improved slowly over several months, finally ending approximately 6 months after the onset of his illness. A repeat gallbladder emptying study done ultrasonographically at that time revealed near-normal meal-stimulated gallbladder emptying. We conclude that poor emptying of the gallbladder may be associated with prolonged abdominal pain in Kawasaki syndrome. Meal-stimulated gallbladder emptying can be assessed by a simple ultrasonographic technique and should be considered in any patient with Kawasaki syndrome and abdominal pain.
