Impact of localized ascites after pediatric living donor liver transplantation: report of three cases.

Fluid collection is common after living donor liver transplantation (LDLT), and can include hematomas, bilomas, abscesses, and seromas. Although accumulated fluid rarely becomes infected and usually remains localized, localized ascites can sometimes be sufficiently extensive to induce vascular complications. This report presents three such cases in pediatric patients that underwent LDLT. A 33-month-old patient showed an increase in the volume of localized ascites around the hepatic vein anastomoses together with low hepatic vein flow on postoperative day (POD) 47. An 82-month-old patient showed an increase in the volume of localized ascites around the portal vein anastomoses together with low portal vein flow on POD 71. A 63-month-old patient showed an increase in the size of a localized abscess around the hepaticojejunostomy with dilatation of all of the intrahepatic bile ducts on POD 20. These cases illustrate the need for awareness of possible vascular or biliary complications due to compressive localized ascites after LDLT.
