Background: Chylous ascites is a rare complication following abdominal radiation or para-aortic lymph node dissection in the management of gynecologic malignancies. Treatment options include dietary restriction with addition of medium-chain triglycerides, serial paracenteses, total parenteral nutrition, and somatostatin. Current opinion advocates that surgical exploration and peritoneo-venous shunts be reserved for refractory cases.
Cases: Two patients developed chylous ascites, one after completion of surgical staging and chemoradiation for stage IIB squamous carcinoma of the cervix and one following para-aortic lymph node dissection for recurrent malignant mixed mullerian tumor of the endometrium. In both cases resolution of the chylous ascites followed placement of a peritoneo-venous shunt.
Conclusions: Chylous ascites should be considered in the differential diagnosis of ascites in patients with gynecologic malignancy treated with radiation or para-aortic lymph node dissection.
