Using intestinal segments during secondary salvage procedures after failed reconstructions of the cervical oesophagus

OBJECTIVES: The free anterolateral thigh (ALT) flap is commonly used for the reconstruction of the cervical oesophagus with satisfactory results. Its convenience and popularity make it a popular flap for reconstructive surgeons. The use of intestinal flaps, however, carries a higher level of technical difficulty and is normally performed as a primary reconstructive procedure. This report investigates the feasibility of intestinal flaps for the reconstruction of the cervical oesophagus and strategies to optimize its success when used as a secondary flap after primary ALT flap failure. METHODS: We retrospectively reviewed 22 patients (age 39-72 years) who were men, between April 2013 and January 2015, with intestinal segments (free and pedicled ileocolon, jejunal and colon flaps) that were used secondarily to salvage failed primary free ALT flap reconstructions after hypopharyngeal cancer resection. Ten patients presented with leakage and 2 with tracheo-oesophageal fistulae as complications from the primary flap failure. RESULTS: Oral intake commenced around 1-month postoperatively. One case of flap failure was observed. The majority had no major postoperative complications. Patients were followed up (6-27 months), and 21 cases of a secondary intestinal flap were successful with the restoration of oesophageal continuity and oral intake. CONCLUSIONS: Intestinal flaps, free or pedicled, can be used secondarily after failed ALT flap reconstructions with minimal complications or morbidity. Intestinal flaps successfully allow restoration of gastrointestinal continuity with early commencement of oral intake and swallowing function.
