Clinical analysis of dilation therapy with Savary-Gilliard dilator under whole direct-viewing endoscope for anastomotic stricture due to post-operative carcinoma of the upper esophagus

Objective To explore the clinical value of dilation therapy with Savary-Gilliard dilator under whole direct-viewing endoscope for anastomotic stricture due to post-operative carcinoma of the upper esophagus. Methods Fifty patients with anastomotic stricture due to post-operative carcinoma of the upper esophagus were randomly divided into two groups: one group patients underwent esophageal dilatation under non-whole direct-viewing endoscope as control, another group patients underwent esophageal dilatation under whole direct-viewing endoscope as treatment group. The dilation success rate and increment value of intraesophageal diameter were compared and analyzed. Results Success rate of dilatation was 84.00% in control group, while 96.00% in treatment(P 0.05). The increment value of intraesophageal diameter was(4.1 ± 1.1)mm in control group, while(6.7 ± 1.3) mm in treatment group(P 0.05). Conclusion In the therapy with Savary-Gilliard dilator under whole direct-viewing endoscope for anastomotic stricture due to post- operative carcinoma of the upper esophagus, the dilatation site could be directly observed and operated. This method was better than traditional esophageal dilatation.
