High-Output Chylothorax: Novel Imaging Techniques Provide Specific Treatment.

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Medical Imaging

Background:

• Postesophagectomy chylothorax presents a significant therapeutic challenge.
• Accurate identification of thoracic duct anatomy and leakage sites is crucial for effective management.
• Current imaging techniques for thoracic lymphatics are often limited in availability and diagnostic capability.

Observation:

• A patient developed chylothorax following esophagectomy, with a confirmed left-sided thoracic duct.
• Intranodal Lipiodol lymphangiography and computed tomography lymphangiography were utilized for lymphatic visualization.
• Fluorescence-guided thoracic duct ligation was performed using robot-assisted thoracic surgery.

Findings:

• The described imaging modalities successfully identified the thoracic duct and leakage site.
• Robot-assisted thoracic surgery enabled precise and effective ligation of the affected thoracic duct.
• The combined approach facilitated successful management of postesophagectomy chylothorax.

Implications:

• These integrated diagnostic and therapeutic techniques offer a viable solution for postesophagectomy chylothorax.
• The described methods can be employed in the postoperative setting to manage chylous fistulas.
• Implementing these strategies may serve as a preventive measure, reducing morbidity and mortality associated with chylothorax after thoracic surgery.
