Colonic Interposition After Adult Oesophagectomy: Systematic Review and Meta-analysis of Conduit Choice and Outcome.

Background: Colonic interposition is a second-line option after oesophagectomy when a gastric neo-oesophagus is not viable. There is no consensus on the optimum anatomical colonic conduit (right or left), or route of placement (posterior mediastinal, retrosternal or subcutaneous). The aim of this review was to determine the optimum site and route of neo-oesophageal conduit after adult oesophagectomy.
