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

Laparoscopic transhiatal en-mass thoracic duct ligation for persistent bilateral spontaneous Chylothorax: A case report

Chylothorax is a rare entity associated with morbidity. Surgical thoracic duct ligation (TDL) by thoracoscopic approach is the recommended choice for persistent chylothorax. However, thoracoscopy is not feasible in case of previous pleurodesis. We describe a successful laparoscopic transhiatal en-mass TDL in a 61-year-old lady for persistent spontaneous chylothorax after failed optimal conservative management and three sessions of pleurodesis. The study shows that laparoscopic transhiatal thoracic duct ligation is an effective alternative in a case where thoracoscopy is not feasible due to various reasons.

Intractable chylous leak after radical esophagectomy treated with radiotherapy

Postoperative chylous leak after esophagectomy is a rare but potentially life-threatening complication that results in hypovolemia, electrolyte imbalance, malnutrition, and immunologic deficiency. However, the management of postoperative chylous leak remains controversial. Following a diagnosis of esophageal cancer, a 64-year-old man was treated by video-assisted thoracoscopic esophagectomy, laparoscopic gastric tube formation, prophylactically thoracic duct ligation, and reconstruction with esophagogastrostomy at the neck level. Massive postoperative drainage from the thorax and abdomen did not initially meet the diagnostic criteria for chylothorax, which was ultimately diagnosed 3 weeks after the operation. Despite various treatments including total parenteral nutrition, octreotide and midodrine, reoperation (thoracic duct ligation and mechanical pleurodesis), and thoracic duct embolization, the chylous leak persisted. Finally, low-dose radiation therapy was administered with a daily dose of 2 Gy and completed at a total dose of 14 Gy. After this, the amount of pleural effusion gradually decreased over 2 weeks, and the last drainage tube was removed. The patient was alive and well at 60 months postoperatively. Herein, we describe a patient with intractable chylous leak after esophagectomy, which persisted despite conservative treatment, thoracic duct ligation, and embolization, but was finally successfully treated with radiotherapy.

"Mega" Cisterna Chyli: A Case Report and Review of the Literature

Enlarged cisterna chyli is an infrequently encountered entity and is most often an asymptomatic, incidental finding on imaging for other reasons. The pathogenesis of cisterna chyli enlargement is not well elucidated and includes infectious, inflammatory, and idiopathic causes. In this report, we present the rare case of an asymptomatic, markedly dilated "mega" cisterna chyli in a 60-year-old female.

Refractory chylous effusions in lymphangioleiomyomatosis patient post lung transplant

Lymphangioleiomyomatosis is a rare systemic disorder of unknown etiology that affects young women almost exclusively. Chylous effusions are known to be associated with lymphangioleiomyomatosis and may be difficult to treat. We present the case of a 37-year-old female who received bilateral lung transplantation for lymphangioleiomyomatosis complicated by refractory chylothorax and chylous ascites, ultimately controlled through repeated, open surgical procedures and percutaneous lymphatic embolization interventions. The combined surgical and interventional radiological approach, while not novel in their own right, suggests that a multi-modal interventional approach may be required in refractory cases.
