Kawasaki disease complicated by gallbladder hydrops mimicking acute abdomen: a report of three cases.

Three cases of gallbladder hydrops associated with Kawasaki disease are presented. The initial manifestations were high fever, jaundice and distended abdomen with guarding. The first two cases received laparotomy under the impression of suppurative cholecystitis with peritonitis. A markedly distended acalculous, nongangrenous gallbladder was noted. A cholecystostomy for drainage was performed. Diagnosis of Kawasaki disease was made only when the clinical manifestations became full-blown postoperatively. Both patients led an uneventful postoperative course. The third case had apparent features of Kawasaki disease at admission though the abdominal symptoms were rather prominent. With supportive care, the patient stabilized by the sixth hospital day without complication and did not require surgical intervention. We suggest that the preferred treatment of abdominal symptoms in Kawasaki disease is medical, and surgical intervention is deserved only for the complications of the hydrops. Simple cholecystostomy seems to be safe and sufficient for such occasion. Ultrasonography is helpful for the correct diagnosis of gallbladder hydrops and can exclude dilatation of the intrahepatic biliary trees and cholelithiasis. Show more
