Traumatic chylothorax most commonly occurs after thoracic surgeries with a few cases reported in patients after abdominal surgery. Effusions usually are caused by a pleural reaction during the postoperative period. However, this can also occur from disruption of the thoracic duct during the surgical procedure. The initial approach is conservative with supportive measures, including drainage by ultrasound-guided thoracentesis and diet modification, and surgery is rarely needed. Having a medical history preceding abdominal surgery is always important to consider the possibility of a pancreatic pleural fistula, which can be excluded by an abdominal computed tomography. Lymphangiography is considered the gold standard diagnostic tool, but its use is limited to cases unresponsive to conservative measures. In this patient, a lymphangiography or surgical intervention was not performed since the patient improved after initial management with no recurrent pleural effusion. A new pleural effusion after abdominal surgery must include chylothorax in the differential diagnosis.
