Fluoroscopically guided balloon dilation for benign anastomotic stricture after Ivor-Lewis esophagectomy: experience...

To evaluate the safety and clinical effectiveness of fluoroscopically guided balloon dilation in 62 patients with benign anastomotic stricture after Ivor-Lewis esophagectomy.

Between January 1996 and June 2004, fluoroscopically guided balloon dilation was undertaken in 62 patients with benign anastomotic stricture after Ivor-Lewis esophagectomy. Radiologic images and medical records including complications were retrospectively reviewed. The maximum diameters of the balloon catheters used were 18-20 mm. Clinical success was defined by the absence of recurrent dysphagia after balloon dilation until the most recent follow-up. The Fisher exact test was used to assess the relationship of symptomatic recurrence and the balloon size, width of the stricture, and radiation therapy.

There were 115 sessions of balloon dilation in 62 patients (mean, 1.85 sessions per patient). Clinical success was achieved in 59 patients (95%) by means of a single dilation (n = 29) or by multiple dilations (n = 30). One patient with severe stenosis was successfully treated with temporary placement of a covered retrievable stent. Major complications such as esophageal perforation or massive bleeding did not occur. Four patients with mucosal tear (n = 3) or aspiration pneumonia (n = 1) were conservatively treated. Patients with severe stricture had more symptomatic recurrences than those with moderate stricture.

Fluoroscopically guided balloon dilation is a safe and successful treatment modality for benign anastomotic stricture after Ivor-Lewis esophagectomy.
