Predictors of @entity86 after esophageal @entity5848 for superficial XXXX .

@entity1 @entity2735 @entity75 @entity1544 @entity5848 @entity86
BACKGROUND AND STUDY AIMS: Although @entity5848 ( @entity5848 ) is becoming accepted as an established treatment for superficial @entity1544 , the risks for developing @entity86 have not been elucidated. @entity1 AND METHODS: This was a retrospective study at a single institution. From January 2002 to October 2008, 65 @entity1 with high-grade @entity2735 treated by @entity5848 were enrolled. Predictors of @entity86 were investigated by comparing results from 11 @entity1 who developed strictures with those from 54 @entity1 who did not. RESULTS: Significant differences between the two groups were observed in longitudinal diameter (45.0 +/- 15.9 mm vs. 31.5 +/- 13.6 mm) and circumferential diameter (37.2 +/- 8.6 mm vs. 26.8 +/- 9.7 mm) of the resected specimens, and the proportion of extension to the whole circumference of the lumen (< 1 / 2/ > 1 / 2/ > 3 / 4 : 2 / 4 / 5 vs. 40 / 13 / 1), histologic depth (HGIN/m2 : 2 / 9 vs. 41 / 13), and procedure time (85.6 +/- 42.8 minutes vs. 53.3 +/- 30.1 minutes). Multivariate analysis revealed that circumferential extension of > 3 / 4 (odds ration [OR]: 44.2; 95 % confidence interval [CI]: 4.4 - 443.6) and histologic depth to m2 (OR: 14.2; 95 %CI: 2.7 - 74.2) are reliable risk factors. Subanalysis for each category by combinations of these risk factors revealed that @entity1 with lesions in > 3 / 4 of the circumferential area were associated with a high rate of @entity86 . By contrast, @entity1 with @entity75 in < 3 / 4 extension have no probability of postoperative strictures. Additionally, subanalysis of @entity1 with m2 lesions in < 3 / 4 circumferential extension revealed that circumferential diameter can be a reliable predictor for @entity86 . CONCLUSIONS: Circumferential extension and histologic depth are the reliable risk factors for postoperative strictures. In combination with circumferential diameter, we can perform effective and appropriate preventive balloon dilatations after esophageal @entity5848 .
