“…There was one case in which dilation was not attempted yet the echoendoscope could not traverse the tumor (staged T3 N1 by limited endosonography). When dilation was performed, the mean largest balloon size used was 15 mm (SD, 2; range, [12][13][14][15][16][17][18][19][20]. Table 2 demonstrates the frequency of maximum balloon diameter size used, the mean starting balloon size for each subsequent maximum balloon size used, and the rate of successful traversal of tumor for each maximum diameter attained.…”

Through-the-Scope Balloon Dilation for Endoscopic Ultrasound Staging of Stenosing Esophageal Cancer

et al. 2007

Dilation of malignant esophageal strictures often is required to complete staging by endoscopic ultrasound (EUS). This study was designed to determine the successful dilation rate (ability to complete staging) and complication rate of through-the-scope (TTS) balloon dilation for malignant esophageal strictures during EUS. We retrospectively reviewed EUS reports for all cases of primary esophageal cancer staged at five centers between January 2002 and October 2004. All dilations were performed with TTS balloons. Among 272 endoscopic ultrasounds, dilation was required in 77 (28%) and was successful in 73 cases (95%). There was one esophageal perforation after dilation (1.3%; 95% confidence interval (CI), 0.2-7) and one esophageal perforation after EUS without dilation (0.5%; 95% CI, 0.1-2.8; P = 0.48 by two-sided Fisher exact test). There were no other major complications. TTS balloon dilation is highly successful in permitting complete staging of obstructing tumors. The rate of complications after dilation with a TTS balloon dilator is low and similar to the baseline rate of EUS in this setting.

“…To determine the complication rate of esophageal cancer dilation, it is important to establish the baseline rate during EUS without dilation [4,17,18]. Siemsen and colleagues [4] reported EUS staging without any dilation among 104 patients.…”
