Resection and anastomosis of the oesophagus and ingluvies are not recommended as the incidence of stricture is much greater. An oesophageal feeding tube may be placed in cases of extensive tissue loss to serve as a stent around which the oesophagus may heal. This will also allow the patient to receive alimentation during the healing period without stressing the repair.
