Hepatic lymphorrhea following pancreaticoduodenectomy: Preliminary diagnosis and treatment experience from case series of four patients

Abstract

IntroductionHepatic lymphorrhea (HL) is an uncommon but potentially life-threatening type of postoperative lymphatic leakage, especially following pancreaticoduodenectomy. Case presentationWe herein report a case series of four patients with HL following pancreaticoduodenectomy that presented to the department with a severe clinical picture with the discovery in imaging and intraperitoneal fluid's tests. All our patients presented with a condition of Hepatic lymphorrhea secondary to pancreaticoduodenectomy, which were treated successfully with percutaneous hepatic lymphangiography (HLG). DiscussionHepatic lymphorrhea is an uncommon but potentially life-threatening complication following pancreaticoduodenectomy. Periportal lymphatic vessels, which was often isolated and dissected especially with extended lymphadenectomy, is potentially damaged and caused resistant chylous leakage. Newly techniques are updated and applied in diagnosis and treatment for this difficult-to-treat complication, one of them is percutaneous Hepatic Lymphangiography (HLG). ConclusionHLG with percutaneous access could be effective to identify and terminate the chylous fistula from periportal lymphatic vessels after pancreaticoduodenectomy.
