Side-to-side choledochoduodenostomy is a safe and effective surgical technique to improve biliary drainage in selected patients. The segment of common bile duct between the anastomosis and the ampulla of Vater may act as a stagnant reservoir or sump. When debris, stones, or infected bile accumulates in the sump, usually because of malfunction of the ampulla of Vater, recurrent abdominal pain or symptoms of cholangitis, pancreatitis, or biliary obstruction may develop. This uncommon (0.14-1.30%) complication is known as the sump syndrome. On imaging studies, diagnostic findings are debris or stone(s) in the common bile duct. Suggestive findings are dilated bile or pancreatic ducts, and changes due to pancreatitis, cholangitis, or liver abscess. Patients with this syndrome frequently have multiple imaging studies before the condition is recognized. The purpose of this essay is to illustrate the imaging findings of this syndrome.
左右肝管十二指肠吻合术是一种安全有效的外科技术，可改善特定患者的胆汁引流。吻合口与 Vater 壶腹之间的胆总管段可能会形成一个停滞的贮液池或积水潭。当碎片、结石或感染性胆汁积聚在积水潭中时，通常是由于 Vater 壶腹功能障碍，可能会出现反复腹痛或胆管炎、胰腺炎或胆道梗阻的症状。这种罕见的（0.14 - 1.30%）并发症被称为积水潭综合征。在影像学检查中，诊断结果是胆总管内有碎片或结石。提示性结果是胆管或胰管扩张，以及由胰腺炎、胆管炎或肝脓肿引起的改变。患有这种综合征的患者在病情被认识之前经常进行多次影像学检查。本文的目的是阐述这种综合征的影像学表现。
