Salvage reconstruction of the oesophagus: a retrospective study of 15 cases

Summary Salvage reconstruction of the oesophagus is still considered a challenging procedure for all head and neck surgeons. The risk of postoperative infection and delayed wound healing is high because of thick scar formation and persistent inflammation. Furthermore, recipient vessels for free tissue transfer or vascular supercharge are not always available. Alimentary tract reconstruction with skin or musculocutaneous flap may be necessary, but this method is susceptible to fistula formation.[Nakatsuka T, Harii K, Asato H, et al. Comparative evaluation in pharyngo-oesophageal reconstruction: radial forearm flap compared with jejunal flap. A 10-year experience. Scand J Plast Reconstr Surg Hand Surg 1998; 32 : 307–10] In the past 10 years, we have experienced 15 cases of salvage reconstruction of the oesophagus after prior cancer treatment or aorto-oesophageal fistula; the cervical oesophagus was reconstructed in five cases and the cervico-thoracic oesophagus in 10. In four cases of cervical oesophagus and six of cervico-thoracic oesophagus we performed free jejunal transfer including two long segment transfers with double vascular pedicle. The cervico-thoracic oesophagus was also reconstructed with pedicled alimentary tract transfer (colon interposition or jejunal pull-up) with vascular supercharge in four cases. In one case, cervical oesophageal defect was reconstructed with a latissimus dorsi musculocutaneous flap. We also used a deltopectoral flap to cover the skin defect in three cases. In three cases, a second salvage operation was necessary because of flap necrosis that was caused by unreliable recipient vessels resulting from scar formation and persistent inflammation. Successful restoration of the oesophagus and oral alimentation was achieved in 11 cases. From this study, we concluded that free jejunal transfer is a useful procedure for salvage reconstruction of the oesophagus, particularly for cervical oesophagus or short oesophageal defects. Nonetheless, surgeons should know the indications and limitations of this procedure thoroughly and always be ready to choose other reconstructive options if necessary.
