Prone position thoracoscopic management of neck chyle leak following major head and neck surgery. A case series.
Main Article Content
Abstract
Chyle leak is a major compication following head and neck surgery, with reported incidence of 0.5% up to 8.3% in published literature. Cervical chyle leak may be challenging to manage with significant morbidity, resulting from extensive fluid and nutritional losses.
This manuscript presents four cases of cervical chyle leak after head and neck surgery. Cervical thoracic duct injury had been identified intra-operatively. Conservative treatment failed to reduce chylous output post-operatively.
All patients were offered thoracocscopic thoracic duct ligation in prone position; thoracic duct was dissected above the right diaphragm and ligated. Immediate resolution of their symptoms followed, with no recurrence at the follow-up period.
Intra-operative repair of cervical thoracic duct remains controversial, while when identified early reduces the following comorbidities. Conservative management addresses reduction of chylous output, while amplifying hydration and alimentation. Thoracoscopic thoracic duct ligation offers a safe and feasible treatment for cervival chyle leak following head and neck surgery with all the advances of minimally-invasive surgery.
