Laparoscopic ligation of cisterna chyli for refractory chylothorax: A case series and review of the literature.

Abstract

We describe an alternative surgical technique for the treatment of chylothorax in patients who have had failure of or are not candidates for transthoracic ligation or embolization by interventional radiology. We describe our experience with laparoscopic ligation of the cisterna chyli in 3 such patients and compare our results with published literature. We used a 5-port approach as for foregut surgery. We retracted the liver, transected the gastrohepatic ligament, and retracted the stomach to the left. We exposed the right lateral aspect of the aorta at the level of the celiac trunk and clipped fatty tissue between the aorta and the right crus. We skeletonized the right crus and dissected from the right crus to the inferior vena cava. We then retracted the inferior vena cava laterally, exposed all soft tissue posteriorly, and identified the cisterna chyli posteromedially to the inferior vena cava. Finally, we ligated and clipped all fatty tissue between the right crus and the inferior vena cava. Success rate was 67%; 1 patient with idiopathic chylothorax did not have resolution and eventually died of multisystem organ failure. There were no procedure-related complications. Laparoscopic ligation of cisterna chyli is an available therapeutic option for patients with chylothorax unresponsive to medical management, embolization, and transthoracic ligation of the thoracic duct. Our series is comparable with other reports of transabdominal approach to chylothorax.
