    Abstract:
    BACKGROUND: Chylous ascites (CA) following pancreatico-duodenectomy (PD) is a rare complication secondary to disruption of the lymphatics during extended retroperitoneal lymph node dissection. The majority of cases do not develop CA, possibly due to patency of the proximal thoracic duct and good collaterals. CA may be due to a consequence of occult obstruction of the proximal thoracic duct by malignant infiltration or tumor embolus. This study was to report the incidence of CA and its outcomes of management. METHODS: A retrospective search of our liver database was performed using the key words "pancreatico-duodenectomy", "chylous ascites" from January 2000 to December 2005. The medical records of CA patients and their management and outcome were reviewed. RESULTS: In 138 patients who had undergone PD in our centre for pancreatic malignancy, 3 were identified with CA and managed by abdominal paracentesis. CA resolved in 2 patients with low fat medium chain triglyceride diet alone and 1 patient had total parenteral nutrition (TPN) for persistent CA. Resolution of CA occurred in these 3 patients at a median follow-up of 4 weeks (range 4-12 weeks). Histologically, resected specimen confirmed pancreatic adenocarcinoma in all the patients. Two patients developed loco-regional recurrences at a median follow up of 8 months (range 6-10 months). And the other was currently disease free at a 10-month follow up. CONCLUSIONS: CA as an uncommon postoperative complication requires frequent paracentesis, prolonged hospital stay, and delayed adjuvant chemotherapy. CA is treated with low fat medium chain triglyceride diet or occasionally TPN is required.
