Background <p>Chylous ascites is an uncommon complication seen in gynecological malignancies. The incidence of postoperative chylous ascites in gynecological malignancies is 0.17%. It is the extravasation of milky chyle into the peritoneal cavity due to lymphatic obstruction or injury diagnosed by detection of triglyceride levels greater than 200&#xa0;mg/dl in ascitic fluid. The site of leakage can be determined by lymphangiography or lymphoscintigraphy. Most of the cases of chylous ascites can be treated by conservative methods like a dietary modification to a low-fat high-protein diet, bowel rest, total parenteral nutrition, medications, large-volume paracentesis. If these measures fail, surgical modalities like laparotomy or peritoneovenous shunting are employed.</p> Case presentation and Conclusion <p>In our case, the patient was successfully managed on dietary modification alone. This case report emphasizes the importance of conservative management for chylous ascites following surgery and radiotherapy in endometrial carcinoma.</p>
