    Abstract:
    OBJECTIVE: To evaluate the endoscopic dilatation of benign esophageal strictures and its outcome. METHODS: A prospective descriptive study was conducted at Surgical Unit 4 of Civil Hospital Karachi, over a period of 24 months, from August 2006 to July 2008. Twenty seven patients with benign esophageal strictures underwent esophageal dilatation under fluoroscopic guidance using Savary Gilliard Dilators and guide wire. Follow up was done weekly for 2 weeks and monthly for a minimum of 6 months. Treatment success was gauged according to improvement of dysphagia. RESULTS: A total of 27 patients were included in the study. There were 16 (59.3%) corrosive strictures, 10 (37%) were peptic strictures and one (3.7%) was due to extrinsic compression. Majority of the corrosive strictures, 11 (68.75%) were suicidal in intent p < 0.001. Mean dilatation frequency for strictures longer than 5cms was 7.10 +/- 5.322 vs. 3.47 +/- 3.281 for strictures < 6cms (p < 0.037). Corrosive strictures were seen more commonly in the upper esophagus as compared to peptic (Mean 22.44 +/- 5.240 cm vs. 30.20 +/- 4.780 cm), p < 0.001. Only 81.4% corrosive stricture could be adequately dilated at initial dilatation as compared to 100% in peptic strictures. Mean symptomatic recurrences per month were 0.6919 +/- 0.300 in corrosives and 0.365 +/- 0.293 in peptic strictures (p < 0.003). There were 4 procedure related perforations, all in patients with corrosive strictures. Overall mortality was 7.4%. CONCLUSION: Endoscopic dilatation is safe and effective in treating benign and corrosive esophageal strictures, which have a higher complication rate. Mean recurrence rate decreased over a period of time in both peptic and corrosive strictures.
