    Abstract:
    OBJECTIVE: To analyze the short- and long-term outcomes following surgical treatment for corrosive stricture of the esophagus. BACKGROUND: Surgery is a well-established treatment for corrosive strictures of the esophagus and involves either resection or bypass of the damaged esophagus and replacement by a conduit. The need for resection and the choice of the ideal conduit for esophageal replacement in these patients continues to be debated and there are only a few studies reporting on the long-term outcome following the surgical treatment. METHODS: This was a retrospective analysis of patients with corrosive stricture of the esophagus who were managed surgically between 1983 and 2009. The type of surgery performed (resection or bypass), the conduit used, the short- and long-term outcomes were assessed. RESULTS: One hundred seventy-six corrosive strictures of the esophagus were managed surgically (resection: 64, bypass: 112). A transhiatal resection could be accomplished in 59 of 62 patients in whom it was attempted. Stomach conduits were used in 107 patients and colonic conduits in 69. The mean operating time was 4.3 ± 1.5 hours and the mean estimated blood loss 592 ± 386 mL. Cervical anastomotic leak occurred in 22 patients (12.5%). Follow up of more than 10 years was available for 78 patients (44.3%) and more than 15 years for 54 patients (30.7%). Recurrent dysphagia developed in 33 patients (18.7%). There were no differences in the short- or long-term outcomes in patients who underwent resection or bypass. The mean duration of surgery, intraoperative blood loss, incidence of conduit necrosis, and in-hospital mortality was significantly lower in patients with stomach conduits as compared with colonic conduits. There was a higher incidence of recurrent laryngeal nerve palsy, recurrent dysphagia, and aspiration after surgery in patients with strictures involving the upper end of the esophagus at or near the hypopharynx. CONCLUSIONS: Satisfactory outcomes are achieved after surgery for corrosive strictures of the esophagus. Resection of scarred esophagus may be done without a substantial increase in the morbidity and mortality; however, the outcomes are not significantly different from bypass. Stomach is a good conduit and the colon should be reserved for cases where the stomach is not available. Long-term outcomes in patients with hypopharyngeal strictures, however, continue to be poor.
