INTRODUCTION: Chylous ascites is an uncommon but potentially life-threatening type of postoperative lymphatic leakage, especially following pancreaticoduodenectomy.
CASE PRESENTATION: A 59-year-old man underwent pancreaticoduodenectomy (PD) with extended lymphadenectomy and segmental Superior Mesenteric Vein (SMV) resection for SMV-involved pancreatic ductal adenocarcinoma (PDAC). After 20th postoperative day, patient had a drain output with a milky appearance, and with a triglyceride level was 1.6 mmol/L, and the daily output volume was up to 1500 mL per day. She has been performed Conventional Lymphangiography (CLAG) to identify the broken lymphatic vessels as well as close the leakage. Following two consecutive lymphangiography, the source of chylous leakage was identified from hilar lymphatic system, and injection of Aetoxisclerol 2% into lymphatic vessels to close the leakage was performed. Partial parenteral nutrition with limited fat components or medium-chain triglyceride (MCT) was administered, and the amount of ascites decreased particularly. The drain was removed in 20th day after the second CLAG. He had no symptoms of abdominal distention after drain removal and had been discharged after 37 postoperative days (PODs).
DISCUSSION: Chylous ascites is an uncommon but potentially life-threatening complication following pancreaticoduodenectomy. Portal lymphatic plexus, 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 transhepatic Conventional Lymphangiography (CLAG).
CONCLUSION: CLAG with percutaneous transhepatic access could be effective to identify and terminate the chylous fistula from portal lymphatic plexus after pancreaticoduodenectomy.
